Frac Sand Reserve:A Frac Sand Reserve is an estimate of tonnage and grade or quality of Frac Sand Resource that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a Frac Sand Resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.
   
Hi-Crush:Hi-Crush Operating, LLC (f/k/a Hi-Crush Inc.) and affiliated companies.
   
Indicated Frac Sand Resource:An Indicated Frac Sand Resource is that part of a Frac Sand Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing, and is sufficient to assume geological and grade or quality continuity between points of observation. An Indicated Frac Sand Resource has a lower level of confidence than that applying to a Measured Frac Sand Resource and may only be converted to a Probable Frac Sand Reserve.
   
Inferred Frac Sand Resource:That part of a Frac Sand Resource for which quantity and quality are estimated based on limited geological evidence and sampling. The level of geological uncertainty associated with an Inferred Frac Sand Resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an Inferred Frac Sand Resource has the lowest level of geological confidence of all Frac Sand Resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an Inferred Frac Sand Resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a Frac Sand Reserve.

Geological evidence is derived from detailed and reliable exploration, sampling, and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A Measured Frac Sand Resource has a higher level of confidence than that applying to either an Indicated Frac Sand Resource or an Inferred Frac Sand Resource. It may be converted to a Proven Frac Sand Reserve or to a Probable Frac Sand Reserve.

Mesh:A measurement of particle size often used in determining the size distribution of granular material. In the US, standard mesh (or sieve) size is defined as the number of openings in one square inch of a screen. For example, a 36-mesh screen will have 36 openings while a 150-mesh screen will have 150 openings. Since the size of the screen (one square inch) is constant, the higher the mesh number the smaller the screen opening and the smaller the particle that will pass through. The following table provides mesh dimensions which are commonly referenced in frac sand specifications:

1.0    EXECUTIVE SUMMARY

 

1.1    Introduction

 

Hi-Crush’s OnCore Plants comprise seven small, built-for-purpose mobile processing plants and one larger modular processing plant (currently under construction) which produce wet (i.e., undried or damp) “100 mesh” frac sand—generally in the 40/140 to 40/200 mesh range—from leased or customer-owned properties. At each OnCore site, Hi-Crush is responsible for mining and processing the raw sand, selling the finished frac sand products, and reclaiming the disturbed land. The mobility of the OnCore Plants provides a great deal of flexibility not afforded to large-scale fixed-plant mining operations.

 

 Hi-Crush retained BOYD to independently prepare estimates of frac sand resources and frac sand reserves for the OnCore Plants. The purpose of this TRS is threefold: (1) to summarize technical and scientific information for the subject mining properties, (2) to provide the conclusions of our review of the information for the properties, and (3) to provide statements of frac sand resources and frac sand reserves for the OnCore Plants in accordance with the disclosure requirements set forth in S-K 1300. 

 

Information used in our assessment was obtained from: (1) data, reports, and other information provided by Hi-Crush, (2) discussions with Hi-Crush personnel, (3) records on file with regulatory agencies, (4) data, reports, and other information from public sources, and (5) nonconfidential information in BOYD’s possession.

 

Unless otherwise noted, the effective date of the information provided herein, including estimates of frac sand resources and frac sand reserves, is December 31, 2023.

 

1.2    Property Description and Location

 

The OnCore Plants are located in West Texas. Most are clustered around the City of Big Spring, Texas, about forty miles east of the Midland-Odessa metropolitan area. The OnCore 7 site is located in the opposite direction, approximately 90 miles west of Midland-Odessa. The general locations of the OnCore Plants are provided in Figure 1.1, following this page.

The OnCore sites comprise approximately 6,480 acres for which surface and sand mining rights are conveyed to Hi-Crush via contractual (“work order”) agreements with the customer-landowner or leases with third parties. These agreements provide Hi-Crush the right to mine, process, and dispose (i.e., sell) of frac sand from the properties.

OnCore 7  Leased   297.0 
OnCore 8  Leased   552.8 
       6,480.0 

 

1.3    Geology

 

The OnCore Plants are all located within an active sand dune belt, in an area of West Texas where the High Plains and Trans-Pecos desert regions converge. The region’s surface is characterized by windblown Quaternary-aged sand formations, including sand dunes, undivided sand and silt deposits, and sheet sand deposits.

 

Most of the OnCore sites are covered by Quaternary sheet and dune sands generally consisting of fine- to medium-grained quartz sand grains mixed with varying degrees of silts, calcareous sands, and caliche nodules. Surficial sand deposition in the study areas may range in thickness from less than 5 ft to over 40 ft. Overburden (i.e., overlying waste) material is generally minimal and easily removed during mining and processing operations. Interbedded alluvial deposits consisting of pebble- to cobble-sized limestone and chert nodules, or caliche are not uncommon, but are easily segregated during mining.

The sand mined at each of the OnCore operations is processed on-site to produce frac sand. Frac sand is a naturally occurring, high silica content quartz sand with grains that are generally well-rounded. The main difference between frac sand and other sands is that frac sand grains are relatively pure in composition, consisting almost entirely of quartz; other sands have numerous impurities that may be cemented to the quartz grains. The pure quartz composition of frac sand grains, along with their homogenous size and well-rounded and spherical shape, gives these sands the characteristics (e.g., crush strength, low acid solubility, low turbidity) that are needed by oil and gas producers for use in developing wells.

 

1.4    Exploration

 

In developing the OnCore sites, Hi-Crush has completed numerous geologic exploration campaigns. A total of 227 drill holes have been completed across the subject OnCore sites. The results of these exploration programs comprise geologic logs and subsurface sand samples, grain size analyses of the samples, and proppant sand testing of composited samples. Exploration summaries were provided to BOYD for our review, along with the collected and analyzed exploration data, which together comprise the primary geologic data used in the evaluation of the frac sand resources and frac sand reserves reported herein.

 

BOYD’s review indicates that the exploration data: (1) were carefully and professionally collected, prepared, and documented, (2) conform with general industry standards, and (3) are appropriate for use in evaluating and estimating frac sand resources and reserves.

 

1.5    Frac Sand Reserves

 

This report provides estimates of frac sand reserves for Hi-Crush’s OnCore Plants in accordance with the requirements set forth in S-K 1300. These estimates were independently prepared by BOYD for the purpose of this report. The reserve estimates are the result of a thorough geologic investigation of the properties, appropriate modeling of the deposits, development of life-of-mine (LOM) plans, and consideration of the relevant processing, economic, marketing, legal, environmental, socio-economic, and regulatory factors.

 

It is BOYD’s independent opinion that the estimated frac sand reserves for the OnCore Plants as of December 31, 2023, total approximately 47.2 million saleable product (i.e., 40/140 to 40/200 mesh frac sand) tons, which are presently controlled by Hi-Crush.

Hi-Crush has a well-established history of mining, processing, and selling frac sand products from their regional operations. BOYD has concluded that sufficient studies have been undertaken to enable the frac sand resources to be converted to frac sand reserves based on established operating methods and forecasted costs and revenues. The forecasted sales prices used in the estimation of frac sand reserves for the OnCore Plants is $23.33 per ton of finished frac sand over the expected life of the reserves (refer to Section 10.5 and Table 12.1 for further details).

 

There are no reportable additional frac sand resources, excluding those converted to reserves, for the OnCore Plants. Quantities of frac sand controlled by Hi-Crush within the defined boundaries of the OnCore properties, which are not reported as frac sand reserves, are not considered to be technically, economically, and/or legally extractable at the time of determination; as such, they are not reportable as frac sand resources in addition to reserves.

1.6Operations

 

1.6.1Mining

 

Contractors are employed to excavate sand and overburden (i.e., overlying waste material) at each of the OnCore Plants. The target sand deposits are excavated using conventional truck and excavator surface mining techniques. Generally, the negligibly thin layer of overburden is mined with the underlying sand. The sand is unconsolidated and does not require drilling or blasting. Excavators and/or front-end loaders are used to load the excavated sand into articulated haul trucks. The haul trucks deliver raw sand material to run-of-mine (ROM) stockpiles located near the processing facilities.

 

1.6.2Processing

 

The OnCore Plants comprise seven smaller mobile wet processing plants and one larger modular wet processing plant (currently under construction). The OnCore operations predominantly produce wet “100 mesh” (i.e., 40/140 to 40/200 mesh) frac sand—that is, the sand is not dried and particles larger than 40 mesh and smaller than 140-to-200 mesh are not considered finished product and are discarded as waste.

 

The small, built-for-purpose mobile OnCore Plants allow Hi-Crush to move sand mining and processing operations from site to site as deposits are depleted. Indeed, Hi-Crush plans to move two plants in 2024—one from the soon-to-be exhausted OnCore 2 site to the unmined OnCore 2B site, and one from the recently exhausted OnCore 3 site to the unmined OnCore 3B site.

 

The seven mobile plants were constructed by Superior Industries, Inc. (Superior). While the plants share nearly identical designs, the latter plants incorporate changes made to the early models to improve production. Each of the mobile processing plants has a nominal (or “nameplate”) capacity of 130 feed tons per hour (tph), which equates to approximately 700,000 to 900,000 tons of finished frac sand per year, depending on the expected processing yields of the sand deposits.

 

Hi-Crush’s modular OnCore 8 processing plant is currently under construction with a planned commissioning in June 2024. Designed by Superior, the OnCore 8 modular processing plant’s design consists of two 250-tph circuits providing a nameplate capacity of 500 tph of feed sand or approximately 3 million tons of finished frac sand per year. The parallel circuit arrangement offers a degree of flexibility as one plant circuit can be idled for maintenance, while the other is operating.

 

JOHN T. BOYD COMPANY

 

 

1-7

 

Each of the OnCore Plants’ processing operations comprise two major components which are typical in the production of wet frac sand. These components include:

 

·Wet Plant – ROM material from the pit is delivered to the wet plant where the coarse material (e.g., gravel) and fine material (e.g., fine sand and silt) is removed from the sand.

 

·Storage and Loadout – Finished damp sand products are stored in stockpiles resting on a water decant system, where the sand is allowed to dry somewhat. The frac sand is then loaded into feed hoppers, conveyed to a discharge hopper, and loaded into trucks resting on weighing scales.

 

1.6.3Other Infrastructure

 

All of the basic infrastructure required for the ongoing operations is in place or under construction at each of the OnCore Plants. The mining and processing operations are supported by the various utilities and transportation networks needed to allow the production and transportation of finished frac sands.

 

BOYD is unaware of any reported interruptions, outages, shortages, or failures related to infrastructure requirements which have materially affected operations at any of the OnCore sites. Given the operation is well-established, we opine that there is low risk of such events materially affecting the estimates of frac sand reserves presented herein is low.

1.7    Financial Analysis

 

1.7.1 Market Analysis

 

Permit submissions for horizontal oil and gas wells in the Permian Basin indicate a continuation of strong drilling ahead. Utilizing data from Baker Hughes and the Railroad Commission of Texas (RRC), the total number of permits filed ranges between 1,000 and 1,600 per quarter in 2023, a strong rebound from the pandemic lows of 2020, as shown in Figure 1.2, below.

 

 

Figure 1.2: Permian Basin HZ Permit Submissions

 

Domestic oil production continues to increase with the Permian leading the way at almost 6 million barrels per day by late 2023, as shown below in Figure 1.3.

1-9

 

Current frac sand production in the Permian Basin is estimated at 60 million to 65 million tons per year with fairly balanced demand and stable pricing. BOYD anticipates stable frac sand pricing substantially above those used to estimate frac sand reserves for the OnCore Plants. Additionally, we anticipate continued upward sand consumption in the basin due to economic and geopolitical influences on energy demand.

 

1.7.2    Capital and Operating Cost Estimates

 

The OnCore Plants’ recent financial performance is summarized as follows:

 

·The OnCore Plants sold approximately 4.7 million tons of finished frac sand in 2023—more than doubling the previous year’s sales. This was primarily due to the commissioning of three additional mobile plants.

 

·Hi-Crush’s average selling price (ASP) for frac sand sold from the OnCore Plants was $21.04 per ton in 2023, increasing 24% from 2022. The four-year historical ASP was $17.62 per ton.

 

·Average cost of goods sold (ACS) was $10.10 per ton sold in 2023, decreasing 20% year-over-year.

 

·EBITDA margin (i.e., EBITDA as a percentage of gross revenue) has remained positive over the past three years and was 48% in 2023.

 

·Capital expenditures totaled approximately $71.4 million (or $8.91 per ton sold) over the last four years.

 

Forward-looking production and unit cost estimates are based on actual past performance and are subject to Hi-Crush’s customary internal budget review and approvals process. In BOYD’s opinion, operating volumes are well-defined and understood, as are mining and processing productivities.

 

The OnCore Plants and related facilities are fully developed or nearly constructed and should not require any near-term major capital investment beyond 2024’s budgeted $44.8 million to maintain full commercial production. Historically, the timing and amount of capital expenditures have been largely discretionary and within Hi-Crush’s control. BOYD projected sustaining capital expenditures is estimated to average $1.20 per ton sold, which includes maintenance of production equipment as well as other items needed for the ongoing operation. This unit cost is based on our judgment and experience with similar operations.

 

Operating cost estimates were developed based on recent actual costs and considering site specific operational activity levels and cost drivers. OnCore’s operating costs are expected to remain relatively consistent (on an uninflated basis) with 2023 results. As such, the projected total cash cost of goods sold over the life of the mine averages $11.57 per ton sold over the life of the mine. BOYD considers the future operating cost estimates to be reasonable and appropriate.

1.7.3    Economic Analysis

 

A consolidated economic analysis of the OnCore Plants was prepared by BOYD for the purpose of confirming the commercial viability of the reported frac sand reserves. Our financial model forecasts future free cash flow from frac sand production and sales over the life cycle of the operation using annual forecasts of production, sales revenues, and operating and capital costs.

 

Table 1.3, below, provides a summary of the estimated financial results (on an aggregate basis) for the remaining life of the OnCore Plants.

Table 1.4 summarizes the results of the pre-tax and after-tax discounted cash flows (DCF) and net present value (NPV) analyses for the OnCore Plants.

 

Table 1.4: DCF-NPV Analysis 
   NPV ($ millions) 
   8%   10%   12% 
Pre-Tax   332.9    309.6    289.0 
After-Tax   265.2    245.8    228.8 

 

The NPV estimate was made for the purpose of confirming the economic viability of the reported proppant sand reserves and not for purposes of valuing Hi-Crush, any of the OnCore operations, or their assets. Internal rate-of-return (IRR) and project payback were not calculated, as there was no initial investment considered in the financial analysis presented herein.

 

It is BOYD’s opinion that the financial model provides a reasonable and accurate reflection of the OnCore Plants’ expected economic performance based on the assumptions and information available at the time of our review.

 

1.8        Permitting and Compliance

 

Several permits are required by federal and state law for mining, processing, and related activities at each of the OnCore operations. BOYD reviewed the permits necessary to support continued operations at each of the OnCore sites. Such required permits appear to be valid and in good standing. The approved permits and certifications are adequate for the continued operation of the mine and processing facilities. New permits, permit revisions, and/or renewals may be necessary from time to time to facilitate future operations. Given sufficient time and planning, Hi-Crush should be able to secure new permits, as required, to maintain its planned operations within the context of current regulations.

 

Mine safety is regulated by the U.S. Department of Labor’s Mine Safety and Health Administration (MSHA). MSHA inspects the facilities a minimum of twice yearly. Hi-Crush’s safety record compares favorably with its regional peers.

 

BOYD is not aware of any regulatory violation or compliance issue which would materially impact the reported frac sand reserves.

1.9       Conclusions

 

It is BOYD’s overall conclusion that the estimates of frac sand reserves, as reported herein: (1) are reasonably supported by sufficient and reliable exploration data, and (2) are reasonably and appropriately supported by technical evaluations, which consider all relevant modifying factors. We are not aware of any other relevant data or information material to the OnCore Plants that would render this report misleading. Our conclusions represent only informed professional judgment.

 

Given the operating history and status of evolution, residual uncertainty (future risk) for this operation is considered minor under the current and foreseeable operating environment. It is BOYD’s opinion that extraction of the frac sand reserves reported herein is technically, legally, and economically achievable after the consideration of potentially material modifying factors. The ability of Hi-Crush, or any mine operator, to recover all the reported frac sand reserves is dependent on numerous factors that are beyond the control of, and cannot be anticipated by, BOYD. These factors include mining and geologic conditions, the capabilities of management and employees, the securing of required approvals and permits in a timely manner, future frac sand prices, etc. Unforeseen changes in regulations could also impact performance. None of the opinions presented herein are intended to represent that BOYD intends or is qualified to render opinions that are legal or accounting in nature.

3.0    PROPERTY OVERVIEW

 

3.1        Description and Location

 

Hi-Crush’s OnCore operations are associated with ten locations spread across five counties—Glasscock, Howard, Loving, Martin, and Midland—in western Texas. Six of the seven mobile OnCore Plants—OnCore 1, 2, 4, 5, 6, and 7—are currently operating. The OnCore 3 site was idled in late-2023 and the mobile plant is moving to the OnCore 3B site in mid-2024. The OnCore 2 site will be decommissioned in mid-2024 and the mobile plant moved to the OnCore 2B site. A larger modular processing plant is currently being constructed on the OnCore 8 site and will be commissioned in mid-2024.

 

Each OnCore plant is located within the Permian Basin and operates in a relatively similar manner, mining and processing local sands to produce a damp “100 mesh” frac sand product, which is used in the hydraulic fracturing process (known as “fracking”) to produce petroleum fluids, such as oil, natural gas, and natural gas liquids.

 

The Midland-Odessa metropolitan area is somewhat central to all of the OnCore Plants. The western-most site—OnCore 7—is located approximately 95 miles west of Midland International Air & Space Port. The northern-most site—OnCore 2B—is located approximately 40 miles to the north-northeast; and the remaining sites located approximately 25 to 55 miles to the northeast of Midland International Air & Space Port.

 

The locations of operating and planned OnCore plants are shown in Table 3.1, below.

3.2        History

 

Extensive surface mining of frac sand has been conducted in the West Texas region since the first “in-basin” frac sand mine—Hi-Crush’s Kermit Mine—commenced production in August 2017, and began supplying locally sourced frac sand into the Permian Basin oil and gas industry. Since then, numerous in-basin frac sand mines have been opened across the region.

 

Hi-Crush developed the OnCore mobile mining and processing concept after completing a series of regional geologic exploration efforts across areas located outside of the historic Permian Basin frac sand mining activity centers. The first OnCore site (OnCore 1) opened in late-2020, and after seeing continued demand for locally sourced damp frac sand, Hi-Crush has now operated a total of seven different OnCore sites since commencing production at OnCore 1. OnCore 3 was recently idled. OnCore 2 is scheduled to be idled in mid-2024. Three new sites—OnCore 2B, 3B, and 8—are scheduled to be online mid-2024. The status of each site is provided in Table 3.2, below.

3.3        Property Control

 

The OnCore sites are primarily operated under lease agreements held between Hi-Crush and various private landowners. However, some OnCore sites are also located on land that is controlled by various Hi-Crush customers. These customers have agreed to allow Hi-Crush to mine sand from their properties under contracts, or “work orders”, that require Hi-Crush to supply minimum quantities of finished frac sand to the landowner at agreed upon prices paid to Hi-Crush.

 

Data provided to BOYD for the OnCore properties included mapping and lease agreements or work orders for each property, which have been accepted as being true and accurate for the purpose of this report.

 

Table 3.3, below, provides a brief overview of the property control status of each OnCore site.

All third-party sales of frac sand produced from the OnCore properties is subject to a royalty payable to the landowners. The blended royalty for the frac sand reserves reported herein is $1.22 per ton sold.

 

3.4        Adjacent Properties

 

Several existing frac sand mining operations are located throughout the West Texas region, however much of the current frac sand mining activity is located near Kermit, Texas. Hi-Crush’s OnCore sites have been located away from the current frac sand mining activity center in an attempt to gain an advantage of shorter haul distances to their end use customers. The closest competitor operations to OnCore’s Delaware Basin sites are Independence Texas, LLC. Tree Dog and Z&T Ranch mines in Loving County, near the idled OnCore 3 site and the OnCore 7 site. OnCore’s Midland Basin operations are more widely distributed, and at present OnCore 2B, 3B, 4, 5, 6, and 8 have no nearby competitors. OnCore 1 and 2 have three nearby competitors: Nomad Proppant Services, LLC, and West Point Silica, LLC both operate on properties adjacent to OnCore 1 to the east and south, respectively. Big Spring Sands, LLC operates a mine 1.5 miles southwest of the OnCore 2 site.

 

There is no information used in this report that has been sourced from adjacent properties.

 

3.5        Regulation and Liabilities

 

The OnCore sites operate under several permits and must comply with other federal, state, and municipal law regulations that do not require a specific permit. Hi-Crush reports that necessary permits are in place or applied for to support immediate operations. New permits or permit revisions may be necessary from time to time to facilitate future operations. Given sufficient time and planning, Hi-Crush should be able to secure new permits, as required, to maintain its planned operations within the context of the current regulations.

 

To the extent known to BOYD, there are no current violations, fines, liens, or other significant factors and risks that may affect access, title, or the right or ability to perform work on the OnCore properties.

3.6        Accessibility, Local Resources, and Infrastructure

 

The OnCore sites all lie within rural regions of western Texas. The surrounding region has a well-established history of heavy oil and gas industry and agricultural development. The nearby Midland-Odessa metropolitan area has a population of 340,391 according to the 2020 U.S. Census. The surrounding counties have a combined population of over 200,000 people, according to 2020 population estimates by the U.S. Census.

 

Finished frac sand products from the OnCore Plants are sold at each site’s mine gate, where finished product is weighed and loaded into bulk trucks. General access to each site is via a well-developed network of primary and secondary roads serviced by local municipality, county, and state governments. These roads offer direct access to each site, and processing facilities and are generally open year-round. Primary vehicular access to the western sites is via Texas state highway TX-302 or U.S. Route 285; while primary access to the eastern sites is via Interstate 20, state highways TX-137, TX-176, TX-137, or TX-349. Each of these roadways provides primary access to various portions of the region’s oil and gas fields.

 

Several regional airports are located throughout the area, and the Midland International Airport is just over two-hours drive from the farthest OnCore location by road.

 

Reliable sources of electrical power, water, supplies, and materials are readily available. Electrical power is provided to the operation by regional utility companies. Water is supplied by the public water system, surface impoundments, and water wells. Additionally, each of the OnCore sites retain recycled processing water as much as possible.

 

3.7        Physiography

 

The western OnCore sites are located within Chihuahuan Basins ecoregion, while the eastern OnCore sites are located within the Arid Llano Estacado ecoregion. In general, the OnCore sites are located in an area of Texas where the southern High Plains and Trans-Pecos regions converge. The area is relatively flat lying with windblown sand hills and dunes in various locations. The surrounding areas generally consist of desert valleys covered with windblown sheet and dune sands, high plains covered with thick alluvium (the Llano Estacado or Staked Plains), or plateaus consisting of thin carbonate-based soils (the Caprock Escarpment). The plateau areas, typically covered by a weathering-resistant caliche (a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt), may abruptly stand up to 1,000 ft above the plains.

 

JOHN T. BOYD COMPANY

 

3-12

 

Each of the OnCore sites themselves are relatively flat, with little topographic relief other than the peaks and troughs of sand dunes. Surface elevations between the OnCore sites range from approximately 2,500 ft above mean sea-level (AMSL) on the eastern sites, to approximately 3,100 ft AMSL on the western sites, however the Caprock Escarpment abruptly rises to an elevation of approximately 3,400 ft AMSL between the eastern and western OnCore site locations.

 

There are not any natural surface waters present on any of the properties.

 

Land cover in the immediate area consists predominantly of mixed shrubbery, grasses, and other various scrub vegetation.

 

3.8            Climate

 

In and around the OnCore sites, summers are long, humid, and hot; the winters are short, cold, and dry; and the skies are mostly clear year-round. Over the course of the year, the temperature typically varies from 32°F to 97°F and is rarely below 22°F or above 105°F.

 

The hot season lasts from mid-May to mid-September, with an average daily high temperature above 89°F. The hottest month of the year is July, with an average high of 97°F and low of 72°F. The cool season lasts from late-November to mid-February, with an average daily high temperature below 67°F. The coldest month of the year is January, with an average low of 33°F and a high of 61°F.

 

Annual precipitation in the area varies widely from year to year, but generally totals 5 to 12 inches of rain with little-to-no snow.

 

In general, the operating season for the OnCore mines is year-round. Adverse weather conditions seldom restrict or interfere with the mining, processing, and loading operations; however, extreme weather conditions may temporarily impact operations. Periodic flooding is possible during heavy rainfall.

4.0            GEOLOGY

 

4.1            Regional Geology

 

Hi-Crush’s eight operating OnCore Plants are located across five counties in West Texas, covering an area that spans approximately 140 miles between the western-most and eastern-most plant sites. The OnCore Plants are all located in relatively similar geologic settings where the High Plains and Trans-Pecos desert regions converge. Surficial geologic units are characterized by windblown Quaternary-aged sand formations, which include varying amounts of sand dunes, undivided sand and silt deposits, and sheet sand deposits. The region is bordered by the Caprock Escarpment of the Llano Estacado to the east and the basins and playas of the Chihuahuan Desert to the west and south.

 

The frac sand resources and frac sand reserves for each of the OnCore sites are hosted in the surficial sand deposits found across the region. The origins of these deposits are believed to be a combination of eroded bedrock material from the southern Rocky Mountains, and locally eroded sandstones. As portions of the southern Rockies were eroded via weathering, particles were carried to the Pecos River. Ancient flooding events of the Pecos River resulted in the suspended particles being deposited into flood plains. Once flood waters receded, winds took over, drying and further transporting these particles over the western Texas region.

 

The Caprock Escarpment of the Llano Estacado marks the eastern-most extent of the surficial sand deposits. Winds transporting particles into the area are thought to have collided with the escarpment, slowing and dropping particles out to where they have accumulated over time. Winnowing processes caused some degree of particle sorting throughout the region to occur. Due to the mechanisms and long distances of particle transport, sand grains were abraded and rounded as they reached their current locations.

 

4.2            Property Geology

 

4.2.1        General Stratigraphy

 

The surficial geologic units at each of the OnCore sites are comprised of undifferentiated Quaternary Age unconsolidated deposits that range in composition from aeolian (windblown) sheet sands and dunes to alluvial sands with silts, clays, and caliche to varying degrees. Geologic mapping in and around the subject properties indicates slight variations in surface geology; however, each OnCore site is in an area where Quaternary-age surficial sand deposits have accumulated. Table 4.1, below, shows the surficial geologic units found on each OnCore property.

As shown, stratigraphic units across the OnCore sites range from generally undifferentiated, windblown sheet sands in the western sites, to Blackwater Draw Formation sand deposits in the eastern sites. A generalized stratigraphic chart of the geologic units found at the OnCore sites is presented in Figure 4.1.

4-3

 

The following text discusses the strata encountered throughout the areas of the current OnCore sites, in depositional order:

 

Ogallala Formation

 

The Ogallala Formation is predominantly comprised of weakly cemented to unconsolidated fine- to medium-grained sands, which may be silty and calcareous in places. A caliche caprock is frequently exhibited, which resists weathering and forms ledges. The thickness of this formation has been recorded up to 550 ft. The Ogallala Formation is rarely encountered at any of the OnCore sites.

 

Blackwater Draw Formation

 

The Blackwater Draw Formation is a predominantly fine to medium-grained quartz sand containing silt, caliche, and calcareous nodules. Thickness is typically 25 ft or less and tends to feather out locally.

 

Quaternary Sheet and Dune Sands

 

Most of the OnCore sites are covered by Quaternary sheet and dune sands generally consisting of fine- to medium-grained quartz sand grains mixed with varying degrees of silts, calcareous sands, and caliche nodules. Surficial sand deposition in the study areas may range in thickness from less than 5 ft to over 40 ft. Overburden (i.e., overlying waste) material is generally minimal and easily removed during mining and processing operations. Interbedded alluvial deposits consisting of pebble- to cobble-sized limestone and chert nodules, or caliche are not uncommon, but are easily segregated during mining.

 

Figures 4.2 through 4.7 (pages 4-6 to 4-11) provide maps of the mineable sand thickness at each of the OnCore sites. Cross-sections through the subject sand deposits are provided in Figures 4.8 through 4.13 (pages 4-12 to 4-17).

 

4.2.2        Structural Geology

 

The structural features of the Quaternary sands in and around the OnCore properties are relatively non-descript. While the subject sand deposits exhibit variable thickness and extents, they are generally unaffected by folding or faulting. Due to the lack of structural features encountered, there are no known geological features that are believed to materially affect frac sand mining operations on the properties; as such, the deposits are considered to be of low geologic complexity.

 

JOHN T. BOYD COMPANY

4.2.3         Frac Sand Geology

 

The sand mined at the OnCore sites is processed into frac sand products. Frac sand is a naturally occurring silica sand—also known as quartz sand or white sand—which generally exhibit the following characteristics required by oil and gas producers for use in developing wells:

 

·High-purity – frac sand grains are relatively pure (typically, >95% silicon dioxide) in composition and almost entirely free from contaminants. Typical sand deposits have numerous impurities fused to the silica grains, such as iron, carbonate, potassium, and other trace elements/minerals, which can make them more susceptible to mechanical and chemical alteration. Mineralogical purity of silica content is a characteristic of mature sand, which has been highly reworked and well sorted, so that the mechanically and chemically less-resistant minerals and fine particles have been dissolved or winnowed away.

 

·Homogeneous grain size – hydraulic fracturing procedures require sand in a relatively narrow range of grain sizes which are dependent on the specific geological conditions of the well and the fracking procedures used. Larger sand grains generally provide better permeability, but smaller sand grains are typically stronger. When describing frac sand, the product is frequently referred to as simply the sieve cut, e.g., 20/40 mesh sand—meaning that 90 percent of the sand is fine enough to pass through a 20-mesh sieve and is coarse enough to be retained on a 40-mesh sieve. Common frac sand sizes include 20/40 mesh, 30/50 mesh, 40/70 mesh, “100 mesh”, “200 mesh”, and finer. The size ranges for “100 mesh” and “200 mesh” vary significantly between manufacturers. As of the date of this report, finer sands such as 40/70 mesh and “100 mesh” have become more widely utilized in shale gas well fracturing.

 

·High sphericity and roundness – Sphericity and roundness describe the overall shape of the sand grains. Sphericity measures how close the grains approach the shape of a sphere while roundness measures the relative sharpness of corners and curvatures of the grains. Greater sphericity and roundness provide better grain strength and porosity/permeability between grains, allowing better flow of oil and gas from the fractures to the wellhead. A more spherical shape also enables the grains to be carried in the fracking fluid with minimal turbulence.

 

·High crush resistance – Crush resistance of frac sand is dependent upon the hardness and shape of the sand grain. Generally, a high percentage of silica in the sand increases its crush resistance. Additionally, monocrystalline grains are stronger than composite grains. Crush resistance is expressed as a K-value that indicates the highest pressure (rounded to the nearest 1,000 psi) that generates less than 10 weight percent fines (i.e., crushed sand grains). For example, a K-value of 7 means that, at 7,000 psi pressure, no more than 10 weight percent fines were generated, but more than 10 weight percent fines were generated at the next highest pressure. The higher the K-value, the more crush-resistant the sand is.

 

·Low acid solubility – Acid solubility is an indication of the amount of soluble cement or soluble mineral grains (i.e., non-silica contaminants) in the frac sand; low solubility requires a high silica content, as pure quartz tends to be insoluble under normal conditions.

 

·Low turbidity – Turbidity is a measure of the clay, silt, or other fine grains and impurities in the sand. Low turbidity is a result of mineralogical maturity and grain-size sorting in the natural depositional environment. Generally, fine suspended matter in the mined sand is washed out during processing, so this property can be somewhat controlled for the final product.

 

Aeolian sand deposits, such as those found on the OnCore sites, which are predominantly comprised of silica sand grains meeting the abovementioned characteristics are well-suited to the commercial production frac sands.

5.0            EXPLORATION DATA

 

5.1            Background

 

In developing the OnCore sites, Hi-Crush has completed numerous geologic exploration campaigns. A total of 227 drill holes have been completed across the subject OnCore sites. The results of these exploration programs comprise geologic logs and subsurface sand samples, grain size analyses of the samples, and proppant sand testing of composited samples. Exploration summaries were provided to BOYD for our review, along with the collected and analyzed exploration data, which together comprise the primary geologic data used in the evaluation of the frac sand resources and frac sand reserves reported herein.

 

Maps illustrating the extents of the sand deposits, along with electronic copies of drilling and sampling logs, as well as sampling procedures and laboratory testing summaries were provided for our review. The equipment utilized, and the sampling, logging, and field work performed, are noted as being appropriate for delineating the frac sand deposits. BOYD opines that the work done by Hi-Crush is thorough and complete for the purposes of evaluating and estimating frac sand resources and reserves on the subject sites.

 

Hi-Crush notes that the OnCore sites have been developed and operated by OnCore personnel from initial greenfield prospecting stages, through current operational status. Generally, each OnCore site has the subject of at least two separate exploration campaigns—the exception being new OnCore sites located adjacent to an operating OnCore site—including a widely-spaced “reconnaissance” exploration campaign to gauge the deposits potential followed by a infill exploration campaign if the initial campaign results are favorable.

5.2Exploration Procedures

 

5.2.1Drilling and Sampling Methodologies

 

Hi-Crush has completed substantial exploration drilling and sampling work across the various OnCore sites. In total, 227 drill holes were completed using the drilling methods specified in Table 5.1. Additional discussion of each drilling method, as well as provided sampling procedures, are presented below:

 

·Direct Push Coring: A skidsteer-mounted AMS Scientific 9520-SK drilling attachment was utilized to advance a 3-in diameter core barrel containing a 1¼ -in diameter, 4-ft long plastic core sleeve into the ground using a hydraulic hammer. Once the core barrel is fully advanced into the ground, the inner core sleeve is removed while the core barrel remains in-place. The sample sleeve is capped on both ends, labeled with drill hole name and interval depths, and the top and bottom of the obtained sample are marked on the core sleeve. A new length of plastic core sleeve is inserted, followed by adding an additional length of core barrel to the top of the drill string, and the hydraulic hammer drives the additional core barrel length into the ground. These procedures are repeated until either meeting refusal (the point at which the hammer cannot advance the drill core any deeper), or to a total depth of approximately 32 ft is reached.

 

Direct push coring is Hi-Crush’s preferred method of exploration, as it provides an intact sample without compromising sample integrity as the drill hole sidewall cannot contaminate samples obtained at increasing depth. Labeled sample sleeves were taken to a secure storage facility, and later cut open for sample description and geologic logging.

 

·Auger Drilling: The AMS 9520-SK attachment is able to switch to utilizing an auger drill to advance through harder materials when required. This method consists of utilizing a 4-in diameter wide and 5-ft long auger flight. As depth increases, drill cuttings are lifted to the ground surface via rotation of the auger. After advancing a complete 5-ft auger length, cuttings from each run were cleaned away from the drill hole collar, quartered, and then sampled before adding another 5-ft length of auger and advancing the hole. Labeled sample sleeves were taken to a secure storage facility, and later cut open for sample description and geologic logging.

 

Auger drilling was only utilized when direct push methods were unable to advance through harder intervals.

·Manual Probe: A JMC PN150 manual subsoil probe advanced a steel core barrel containing a 0.8-in diameter, 3-ft long core sleeve by manually lifting and dropping a slide-hammer mounted on a vertical rod. Once the core barrel is advanced into the ground, the core sleeve is retrieved using a manual step-jack, while the core barrel remains in the ground. The sample sleeve is capped on both ends, labeled with drill hole name and interval depths, and the top and bottom of the obtained sample are marked on the core sleeve before a new sleeve is inserted into the core barrel, and an additional length of core barrel is placed on top of the drill string. These procedures are repeated until either meeting refusal, or a total depth of approximately 15-ft is reached. Labeled sample sleeves were taken to a secure storage facility, and later cut open for sample description and geologic logging.

 

·Rotosonic Drilling: A drilling contractor operates a track-mounted rotosonic drilling rig, which utilizes a combination of rotary core drilling and a vibratory drilling head to advance core barrels through poorly consolidated lithologies. Rotosonic drilling provides relatively undisturbed drilling cores with typically very high recoveries. After advancing 10-ft of drilling core into the ground, a 4-in diameter core is retrieved and extruded into plastic sleeves, which are labeled with the bottom depth of each drilling run. These sample bags were logged and sampled on-site, with sampling consisting of taking approximately one-quarter of the entire length of the drilled core in order to obtain a composited representative sample of the drilled interval. Obtained sample material is placed into heavy-mil sample bags, which are then labeled with drill hole name and sample top and bottom depths, and then taken to a secure storage facility.

 

Please refer to Figures 4.2 through 4.7 (pages 4-6 to 4-11) for the locations of rotosonic drill holes completed by Hi-Crush on the various OnCore sites.

 

5.2.2Proppant Sand Testing

 

Samples obtained throughout Hi-Crush’s OnCore exploration campaigns were transported by Hi-Crush personnel to secure storage facilities after completion of each drilling campaign. These facilities, owned by Hi-Crush, are located in either Dallas or Houston, Texas. Once samples arrived and were catalogued, any samples still in capped sample sleeves were cut open to be geologically logged at the storage facilities. Once all samples were geologically logged, mineable intervals were determined by a Hi-Crush geologist, and composite samples of the mineable sand intervals were created to be analyzed for particle size distributions. The composite samples were then transported by Hi-Crush, to either PropTester Inc’s. (PropTester) laboratory in Cypress, Texas, or Hi-Crush’s in-house sample trailer located at their Kermit Mine.

The general procedure for particle size distribution analyses was as follows:

 

1.The sample was dried to remove moisture.

 

2.A 600- to 1,200-gram subsample was collected and weighed.

 

3.The subsample was placed in a blender for three minutes to break up the material as much as possible.

 

4.The blended subsample was then placed on a 200-mesh wash screen, and thoroughly washed to remove any fine materials (e.g., clays and silts).

 

5.The remaining larger than 200 mesh (+200 mesh) material is then dried and weighed to determine the mass of fines that were washed out (i.e., wash loss).

 

6.The cleaned subsample was then either placed into a sieve stack of different mesh sizes and agitated for a period of 20 minutes, or run through a high-speed photographic particle size analyzer (i.e., CAMSIZER) to determine the particle size distribution of the subsample.

 

Hi-Crush also obtained various finished product and composite drill hole samples, which were delivered to PropTester for standard frac sand characteristic testing according to API RP 19C/ISO 13503-2, Measurement of Properties of Proppants Used in Hydraulic Fracturing and Gravel-packing Operations (API/ISO). Results on API/ISO testing are presented in Section 5.3.2.

 

5.2.3Other Exploration Methods

 

To our knowledge, no other methods of exploration (such as airborne or ground geophysical surveys) were completed on the OnCore sites.

 

5.3Laboratory Testing Results

 

The relatively uniform nature of the mineable portion of the sand deposits found on the various Hi-Crush OnCore sites, combined with the results of laboratory testing, indicate the subject properties can produce a combination of finished “100 mesh” frac sand products—typically in the 40/140 to 40/200 mesh size range—that meet various local Permian Basin customer specifications.

5.3.1Grain Size Distribution

 

Grain size distribution was analyzed according to API/ISO, Section 6. A table of the weighted average particle size distribution of the in-situ sand deposit, as derived from laboratory testing results, is shown in Table 5.2 below.

The preceding table highlights the relative fineness of the sand found within the subject OnCore sites, indicating most of the sand particles are concentrated between the “passing 40 mesh” and “retained by 140 mesh” size fraction. Accordingly, the OnCore sites produce a principal marketable “100 mesh” product.

 

5.3.2Quality Summary

 

As general customer specifications tend to adapt to the local sand characteristics, API/ISO testing for locally sourced frac sands has become less relevant over the past several years. However, it is still of value to be able to demonstrate that the frac sand produced at a mine meets specifications for certain well applications.

Hi-Crush obtained various finished product loadout samples of finished product and composite drill hole samples from each OnCore site. These samples were delivered to PropTester for API/ISO frac sand analysis of frac sand characteristics. Additional turbidity testing is conducted in-house by Hi-Cruch as part of their quality control measures. The resulting proppant performance test results for each OnCore site are summarized in Table 5.3, below.

*100 mesh proppant sand material does not have an API/ISO specification.

 

While 100 mesh frac sands do not have API/ISO specifications, sample testing results, and Hi-Crush’s demonstrated commercial success producing and selling frac sands from their various OnCore sites to local Permian Basin oil and gas producers suggest the sand has been shown to meet customer specifications.

 

5.4Data Verification

 

For purposes of this report, BOYD did not verify historic drill hole data by conducting independent drilling in areas already explored. It is customary in preparing frac sand resource and reserve estimates to accept basic drilling and quality testing data as provided by the client, subject to the reported results being judged representative and reasonable.

 

BOYD’s efforts to judge the appropriateness and reasonability of the source exploration data included reviewing provided drilling logs, sampling procedures, sand quality testing results, and discussing related aspects of the OnCore deposits and processing operations with Hi-Crush personnel.

5.5Adequacy of Exploration and Sampling Data

 

BOYD’s review of the reported procedures indicate the exploration and sampling data obtained for the OnCore sites were: (1) carefully and professionally collected, prepared, and documented in conformance with general industry standards, and (2) are appropriate for use of evaluating and estimating frac sand resources and frac sand reserves. Similarly, BOYD’s review of testing data provided by Hi-Crush suggests that the analyses completed are generally appropriate to determine frac sand characteristics and determine the subsequent quality of finished frac sand products. As such, it is BOYD’s opinion that the sampling data are also suitable for use in the estimation of frac sand resources and frac sand reserves on the various OnCore sites.

6.0          FRAC SAND RESOURCES AND RESERVES

 

6.1Applicable Standards and Definitions

 

Unless otherwise stated, frac sand resource and frac sand reserve estimates disclosed herein are completed in accordance with the standards and definitions provided by S-K 1300. It should be noted that BOYD considers the terms “mineral” and “frac sand” to be generally interchangeable within the relevant sections of S-K 1300.

 

Estimates of any mineral resources and reserves are always subject to a degree of uncertainty. The level of confidence that can be applied to a particular estimate is a function of, among other things: the amount, quality, and completeness of exploration data; the geological complexity of the deposit; and economic, legal, social, and environmental factors associated with mining the resource/reserve. By assignment, BOYD used the definitions provided in S-K 1300 to describe the degree of uncertainty associated with the estimates reported herein.

 

The definition of mineral (frac sand) resource provided by S-K 1300 is:

 

Mineral resource is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

 

Estimates of frac sand resources are subdivided to reflect different levels of geological confidence into measured (highest geologic assurance), indicated, and inferred (lowest geologic assurance). Please refer to the Glossary of Abbreviations and Definitions for the meanings ascribed to these terms.

 

The definition of mineral (frac sand) reserve provided by S-K 1300 is:

 

Mineral reserve is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.

 

JOHN T. BOYD COMPANY

 

 

6-2

 

Estimates of frac sand reserves are subdivided to reflect geologic confidence, and potential uncertainties in the modifying factors, into proven (highest assurance) and probable. Please refer to the Glossary of Abbreviations and Definitions for the meanings ascribed to these terms.

 

Figure 6.1 shows the relationship between frac sand resources and frac sand reserves.

 

 

Figure 6.1: Relationship Between Frac Sand Resources and Frac Sand Reserves

 

In this report, the term “frac sand reserves” represent the tonnage of frac sand products that meet customer specifications and will be available for sale after processing of the ROM sand.

 

6.2Frac Sand Resources

 

6.2.1Methodology

 

BOYD independently prepared estimates of in-place frac sand for each of Hi-Crush’s OnCore sites by performing the following tasks:

 

1.The top and bottom elevations of the mineable sand interval of each site was interpreted from drill hole records and sand particle size analyses. The sands mined at the various OnCore sites are generally present at the surface. As there is little-to-no overburden, the top of the mineable sand unit is considered to be the current ground surface or directly beneath a thin soil interval noted in drilling logs. The bottom of the mineable sand unit is delineated by the depth at which drilling was terminated, or an underlying caliche interval was encountered.

 

JOHN T. BOYD COMPANY

 

 

6-3

 

2.Interpreted drill hole records were compiled and validated. Strata thicknesses were aggregated, and sand particle size analyses of the sand unit were composited for each data point. The compiled drill hole data were then imported into either Carlson Software or Vulcan geologic modeling and mine planning software, both of which are geologic modeling and mine planning software suites that are widely used and accepted by the mining industry.

 

3.A geologic model of each site’s deposit was created using industry-standard grid modeling methods well-suited for simple stratigraphic deposits. The geologic models delineate the top and bottom of the mineable sand horizon and the distribution of the product size fractions across each of the OnCore site deposits.

 

4.After reviewing the continuity and variability of each deposit, suitable resource classification criteria were developed and applied as per the discussion in Section 6.2.2.

 

5.Contiguous areas of remaining mineable sand within the various OnCore sites were delineated using the criteria described in Section 6.2.3, in addition to utilizing mapping of remaining mineable areas as provided by Hi-Crush, as well as considering the following assumptions for each OnCore site:

 

a.Pit wall slopes of 3:1 (approximately 19 degrees).

 

b.Areas mined prior to December 31, 2023, were delineated from surveyed topography and/or aerial imagery and excluded from the estimates of frac sand resources.

 

6.In-place volumes for each of the remaining mining areas were calculated from the geologic model within the modeling software. A dry, in-place, bulk density of 100 pounds per cubic foot was used to calculate the in-place tonnage of frac sand.

 

7.Where warranted, adjustments are made to the estimates using production records to reconcile differences between the date of the ground survey/aerial imagery and the effective date of the estimates.

 

JOHN T. BOYD COMPANY

6.2.2Classification

 

Geologic assuredness is established by the availability of both structural (thickness and elevation) and quality (size fraction) information for the deposit. Resource classification is generally based on the concentration or spacing of exploration data which can be used to demonstrate the geologic continuity of the deposit. When material variations in thickness, depth, and/or sand quality occur between drill holes, the allowable spacing distance between drill holes is reduced. The drill hole spacing criteria established by BOYD after a review of the available exploration data and geologic models and used to classify the frac sand resources of each OnCore site are provided in Table 6.1, below.

 

Table 6.1: Frac Sand Resource
Classification Criteria
 
   Nominal Maximum 
Classification  Spacing Requirment (ft) 
Measured   1,500 
Indicated   2,500 
Inferred   5,000 

 

Extrapolation or projection of resources in any category beyond any data point does not exceed half the point spacing distance.

 

The surficial sand deposits located on the OnCore sites are considered to be of low geologic complexity. We believe these criteria appropriately reflect their implied levels of geologic assurance with respect to the estimation of frac sand resources. Since sufficient drilling and sampling has been performed within the remaining mineable portions of each site, BOYD is of the opinion that there is a low degree of uncertainty associated with the estimates of frac sand resources provided herein.

 

6.2.3Estimation Criteria

 

Development of the frac sand resource estimates for each OnCore site assume mining and processing methods and equipment that have been utilized by Hi-Crush successfully at these types of operations for several years.

 

The target mining horizon at each of the OnCore sites generally manifests as a continuous, low rolling sand unit with relatively consistent depth, thickness, and quality on each site. There is little-to-no overburden, and the high-quality sand is easily distinguished from any waste units; as such, interpretation of the mineable horizon is relatively easy. The mined sand is processed to remove intervals of caliche and any out-sized material (i.e., sand which is either too coarse or silts/clays which are too fine to be sold) and produce saleable finished products. The amount of finished sand produced as a percentage of the raw sand mined is referred to as the processing yield (or plant yield), which is analogous to the “cut-off grade” of other mining operations. If the expected processing yield of the sand is too low, the costs of production will outweigh sales revenues and the deposit cannot be economically mined. The minimum economic processing yields range from approximately 30–40% based on Hi-Crush’s historical and forecasted economics (refer to Chapters 10 through 12); however, this is well below the expected processing yields of each of the OnCore sand deposits. Other limiting criteria, such as minimum mining thicknesses or maximum stripping ratios (the ratio of waste to sand excavated) are generally not considered in the estimation of frac sand resources for the OnCore sites.

 

JOHN T. BOYD COMPANY

 

 

6-5

 

The limits of the frac sand resources are constrained to those portions of the interpreted sand deposit that:

 

·Are reasonably defined by available drilling and sampling data.

 

·Contain products that meet generally accepted specifications and can be sold at a profit (i.e., be economic).

 

·Honor any legal mining constraints (e.g., property boundaries, environmental setbacks, utility and infrastructure setbacks, etc.).

 

·Adhere to physical mining limitations.

 

Frac sand resources for the OnCore sites are assessed for reasonable prospects for eventual economic extraction by reporting: (1) those resources which have been subsequently converted to proppant sand reserves after the application of all material modifying factors, and/or (2) those resources which have similar characteristics (i.e., mining conditions, and expected processing yields and qualities) to those converted to frac sand reserves.

 

The criteria employed in developing the estimates of frac sand resources for each OnCore site are supported by historical results and align with those employed at similar operations. As such, it is BOYD’s opinion that the stated criteria are reasonable and appropriate for the estimation of frac sand resources at the OnCore sites.

 

6.2.4Frac Sand Resource Estimate

 

There are no reportable frac sand resources excluding those converted to frac sand reserves for all of the OnCore sites. Quantities of frac sand controlled by Hi-Crush within the defined boundaries of each OnCore site which are not reported as frac sand reserves, are not considered to have potential economic viability; as such, they are not reportable as frac sand resources.

 

6.2.5Validation

 

BOYD independently estimated in-place frac sand resources for each OnCore site from the drilling, sampling, and testing data provided by Hi-Crush. We have reviewed this information, on a representative basis, by confirming the accuracy of geologic model inputs by comparison with drilling logs and laboratory reports. We have developed stratigraphic grid models of the subject sand deposits and compared these with the provided exploration data. It is BOYD’s opinion that the geologic models are representative of the informing data and that the data are of sufficient quality to support the frac sand resources estimate provided herein. Furthermore, it is our opinion that the resource estimation methods and criteria employed are both appropriate and reasonable for these deposit types and proposed extraction methods.

6.3Frac Sand Reserves

 

6.3.1Methodology

 

Estimates of frac sand reserves for the OnCore sites were derived contemporaneously with estimates of frac sand resources. To derive an estimate of saleable product tons (frac sand reserves), a mining recovery and a processing recovery were applied to the in-place resource estimate. The mining recovery factor will determine the ROM sand tonnage that will be delivered to the processing facilities, while the processing yield accounts for the removal of out-sized (i.e., larger than 40 mesh and smaller than 140 mesh) material and losses during processing due to minor inefficiencies. Recoveries for each OnCore site were derived from sample sizing data, expected operating performance, and historical operating results, and are shown in Table 6.2 below:

 

Table 6.2: Mining and Processing Recoveries
 
   Recovery (%) 
Site  Mining   Processing   Overall 
OnCore 1   90    80    72 
OnCore 2   90    81    73 
OnCore 2B   90    73    66 
OnCore 3B   90    67    60 
OnCore 4   90    65    59 
OnCore 5   90    69    62 
OnCore 6   90    66    59 
OnCore 7   90    64    58 
OnCore 8   90    76    68 
Average - All OnCore Plants   90    69    62 

 

6.3.2Classification

 

All of the estimated frac sand reserves are derived from either Measured frac sand resources or Indicated frac sand resources, in accordance with S-K 1300, and are therefore classified as either Proven or Probable frac sand reserves accordingly, after BOYD was satisfied that the frac sand reserve classification reflects the outcome of technical and economic studies. Figures 6.2 through 6.7, following this text, illustrate the reserve classifications of each OnCore site’s frac sand deposit.

6.3.3Frac Sand Reserve Estimate

 

BOYD’s estimate of surface mineable frac sand reserves for the OnCore Plants totals nearly 47.2 million saleable product tons, as of December 31, 2023. The frac sand reserves reported in Table 6.2, below, are based on individual LOM plans which, in BOYD’s opinion, are technically achievable and economically viable after the consideration of all material modifying factors.

 

Table 6.3: Frac Sand Reserves (as of December 31, 2023)
 
   Mesh     Product Tons (000) by Classification 
Plant  Size  Control  Proven   Probable   Total 
OnCore 1  40/140  Leased   3,360    -    3,360 
      Work Order   -    1,149    1,149 
      Subtotal   3,360    1,149    4,509 
OnCore 2  40/140  Leased   375    -    375 
OnCore 2B  40/140  Leased   -    5,130    5,130 
OnCore 3B  40/140  Work Order   -    3,418    3,418 
OnCore 4  40/140  Leased   2,232    668    2,900 
Oncore 5  40/140  Leased   4,297    7,282    11,579 
OnCore 6  40/140  Leased   5,146    -    5,146 
OnCore 7  40/140  Leased   3,810    4,692    8,502 
OnCore 8  40/140  Leased   5,613    -    5,613 
Total - All OnCore Plants      24,833    22,339    47,172 

 

The frac sand reserves of the OnCore Plants are well-explored and defined. It is our conclusion that nearly 53% of the stated reserves can be classified in the Proven reliability category (the highest level of assurance) with the remainder classified as Probable.

 

Hi-Crush’s OnCore Plants, and other frac sand mining operations in the area, have a well-established history of mining and selling frac sand products into the local Permian Basin energy fields. BOYD has assessed that sufficient studies have been undertaken to enable the frac sand resources to be converted to frac sand reserves based on current and proposed operating methods and practices. Changes in the factors and assumptions employed in these studies may materially affect the frac sand reserve estimate.

 

JOHN T. BOYD COMPANY

 

 

6-8

 

The economic viability of the stated frac sand reserves is demonstrated by the production and financial projections and marketing information presented in Chapters 10 through 12 of this report. The forecasted sales prices used in the estimation of frac sand reserves for the OnCore Plants is $23.33 per ton of finished frac sand (refer to Section 10.5 and Table 12.1 for further details).

 

6.3.4Significant Risks and Uncertainties

 

The extent to which the frac sand reserves may be affected by any known geological, operational, environmental, permitting, legal, title, variation, socio-economic, marketing, political, or other relevant issues has been reviewed. If and as warranted. It is the opinion of BOYD that Hi-Crush has appropriately mitigated, or has the operational acumen to mitigate, the risks associated with these factors. BOYD is not aware of any additional risks that could materially affect the development of the frac sand reserves.

 

Given the data available at the time this report was prepared, the estimates presented herein are considered reasonable. However, they should be accepted with the understanding that additional data and analysis available after the date of the estimate may result in a change to the current estimate. These revisions may be material.

 

Based on our independent estimate and operations review, we have a high degree of confidence that the estimates shown in this report accurately represent the available frac sand reserves controlled by Hi-Crush at the OnCore Plants, as of December 31, 2023.

7.0            MINING OPERATIONS

 

7.1            Mining Method

 

The windblown sheet sands and sand dunes in and around the OnCore properties are loosely consolidated and generally overlain by very little overburden; characteristics which are amenable to the use of conventional surface mining techniques. Since most of the target sand formations are very shallow and do not extend below the water table, each is ‘dry-mined’ using medium-sized earthmoving equipment (i.e., haul trucks and excavators). Where the thickness of the sand deposits are greater than the digging depth of the excavating equipment, mining occurs in a series of benches arranged in a stair-like fashion to recover sand from the top of the formation (in elevation) down to the lowest practical elevation.

 

Most of the mineable areas have minimal overburden and vegetation; as such, sand excavation normally begins at the surface. Where present, overburden is stripped from the surface of the sand deposit utilizing bulldozers, loaders, excavators, and haul trucks. The overburden is placed away from the sand dunes in berms or stockpiles which will be planted (i.e., vegetated) to minimize erosion of the material after completion. Where present, interbedded waste material (e.g., caliche) is separably removed and stored elsewhere on the property or used in the construction of berms.

 

Drilling and blasting are not required for the loosely consolidated sand and waste material. Excavators and front-end loaders are used to load the mined or ROM sand material into articulated haul trucks, which transport the sand to a ROM stockpile near the processing plants.

 

Once the mineable interval of sand is excavated, some of the mined-out pits will be used to store reject material from the processing operations.

 

JOHN T. BOYD COMPANY

 

 

7-2

 

7.2            Mine Schedule, Equipment, and Staffing

 

Sand excavation at each of the OnCore operations is performed by outside earthmoving contractors. Each of the mining contractors is contractually obligated to supply their respective OnCore sand processing facilities with sufficient feed material to ensure continuous operations. Mining operations are conducted as required year-round but are generally restricted to 12 hours per day.

 

The primary mobile equipment involved in sand excavation, stockpiling, and hopper feeding includes:

 

·Excavators,

 

·Articulated haul trucks,

 

·Front end loaders,

 

·Dozers,

 

·Water truck, motor grader, and other ancillary equipment.

 

Most of the mobile equipment fleets are owned and operated by the mining contractors. Regular and major repair maintenance of the fleets is also the contractors’ responsibility. If maintained in good condition, the mobile equipment fleets should be capable of achieving the production levels required by the LOM plans.

 

Staffing requirements for the mining operations are the responsibility of the earthmover contractors.

 

7.3            Engineering and Planning

 

The primary mine planning consideration for each operation is the safe, economical, and regular supply of raw high-quality sand feed to the processing plants. In commercial mining terms, the quantities of overburden removed, and sand mined each year at each of the OnCore Plants are considered modest. Each of the sand deposits affords easy access because of their shallow depth and large areal extent. As such, mining plans for the OnCore operations are relatively simple and very flexible; able to be modified based on demand in a relatively short time frame.

 

Geotechnically, the sand deposits are relatively competent, and the mining depths are so shallow that slumping, or collapsing, has not been and is not expected to be a detriment to the mining process. The pit design parameters utilized at each of the operations have been used with success at similar sand mining operations for many years.

 

JOHN T. BOYD COMPANY

 

 

7-3

 

Excessive inflow of groundwater into the mining pits is not expected. As such, dewatering before or during mining activities should be manageable with drainage ditches and sumps. Flood waters from localized flash floods are a manageable risk. Onsite water ponds can be used to hold any excessive ground or storm water.

 

7.4            Mining Sequence and Production

 

The areal extents of the remaining mining areas (as shown in Figures 6.2 to 6.7, on pages 6-9 to 6-14) and the geologic characteristics of the sand deposits afford the OnCore operations some degree of operational and planning flexibility. Generally, mining operations are expected to advance in blocks outwards from their respective processing plants to reduce haul distances and expand waste storage capacity.

 

As previously mentioned, the key driver of the mining operations is the adequate supply of feed material to the OnCore processing plants. Mine production requirements and expected mine life for each of the OnCore sites is shown in Table 7.1. below.

 

Table 7.1: Annual Production Requirements and
Expected Mine Life

In 2023, almost 5.7 million tons of raw sand were excavated at the seven active OnCore operations. This was up 87% (or 2.6 million tons) from the previous year when only four OnCore sites were active. With the planned mid-year commissioning of OnCore 8, Hi-Crush plans to mine approximately 8 million tons of raw sand in 2024, as shown in Figure 7.1, below.

 

 

 

Figure 7.1: LOM Forecasted Mining Production

 

Future mine production, and hence the longevity of the mines, is directly related to the energy market demand for proppant sand. Actual yearly production volumes may, and are likely to, fluctuate significantly based on this demand. The presented LOM plans are based on Hi-Crush’s controlled (via lease or service agreement) frac sand reserves. Hi-Crush actively investigates additional sand deposits to utilize their OnCore fleet of mobile processing plants; however, there is no guarantee that additional frac resources or reserves will be available for Hi-Crush to acquire.

 

It is BOYD’s opinion that the forecasted production levels for the OnCore Plants—both individually and collectively—are reasonable, logical, and consistent with typical surface sand mining practices in the region.

 

JOHN T. BOYD COMPANY

7.5            Mining Risks

 

Surface mines face two primary types of operational risks. The first category of risk includes those daily variations in physical mining conditions, mechanical failures, and operational activities that can temporarily disrupt production activities. These conditions/circumstances can adversely affect production on any given day but are not regarded as “risk issues” relative to the long-term operation of the mine. Instead, these are considered “nuisances” that, while undesirable, are encountered on a periodic basis at many mining operations. BOYD does not regard these issues as being material to the OnCore Plants’ operations or otherwise compromising its forecasted performance.

 

The second type of risk is categorized as “event risk”. Items in this category are rare, but significant, occurrences that ultimately have a pronounced impact on production activities and corresponding financial outcomes. Examples of event risks are major fires or explosions, floods, or unforeseen geological anomalies that disrupt extensive areas of proposed or operating mine workings and require alterations of mining plans. Such an event can result in the cessation of production activities for an undefined but extended period (measured in months, and perhaps years) and/or result in the sterilization of frac sand reserves. This type of risk is minimal in a relatively simple surface frac sand mining operations such as those of the OnCore Plants.

8.0            PROCESSING OPERATIONS

 

8.1            Overview

 

The OnCore Plants comprise seven smaller mobile wet processing plants and one larger modular wet processing plant (currently under construction). The OnCore operations predominantly produce wet “100 mesh” (i.e., 40/140 to 40/200 mesh) frac sand—that is, the sand is not dried and particles larger than 40 mesh and smaller than 140-to-200 mesh are not considered finished product and are discarded as waste.

 

The small, built-for-purpose mobile OnCore Plants allow Hi-Crush to move sand mining and processing operations from site to site as deposits are depleted. Indeed, Hi-Crush plans to move two plants in 2024—one from the soon-to-be exhausted OnCore 2 site to the unmined OnCore 2B site, and one from the recently exhausted OnCore 3 site to the unmined OnCore 3B site. Table 7.1., below, provides the start-up (or commissioning) date for each of the mobile OnCore Plants.

 

Table 8.1: Mobile OnCore Plant
Commisioning Dates
Plant    Commisioned
OnCore 1    September 2020
OnCore 2    April 2020
OnCore 3    February 2022
OnCore 4    July 2022
OnCore 5    October 2022
OnCore 6    May 2023
OnCore 7    July 2023

 

The seven mobile plants were constructed by Superior Industries, Inc. (Superior). While the plants share nearly identical designs, the latter plants incorporate changes made to the early models to improve production. Each of the mobile processing plants has a nominal (or “nameplate”) capacity of 130 feed tons per hour (tph), which equates to approximately 700,000 to 900,000 tons of finished frac sand per year, depending on the expected processing yields of the sand deposits.

 

Hi-Crush’s modular OnCore 8 processing plant is currently under construction with a planned commissioning in June 2024. Designed by Superior, the OnCore 8 modular processing plant’s design consists of two 250-tph circuits providing a nameplate capacity of 500 tph of feed sand or approximately 3 million tons of finished frac sand per year.

The parallel circuit arrangement offers a degree of flexibility as one plant circuit can be idled for maintenance, while the other is operating.

 

8.2            Processing Method

 

Each of the OnCore Plants’ processing operations comprise two major components which are typical in the production of wet frac sand. These components include:

 

·Wet Plant – ROM material from the pit is delivered to the wet plant where the coarse material (e.g., gravel) and fine material (e.g., fine sand and silt) is removed from the sand.

 

·Storage and Loadout – Finished damp sand products are stored in stockpiles resting on a water decant system, where the sand is allowed to dry somewhat. The frac sand is then loaded into feed hoppers, conveyed to a discharge hopper, and loaded into trucks resting on weighing scales.

 

8.2.1Wet Plant

 

Each wet plant receives its raw sand feed from a ROM stockpile which is supplied by the mine. A front-end loader loads the ROM sand into a grizzly or scalping screen feed hopper. The oversized material is screened out and the remaining sand is mixed with water to be pumped to and processed through the wet plant.

 

The wet plants do not crush the material, but instead scrub (i.e., wash) and classify (i.e., size) the raw sand. During this process, a screen removes the plus 25 mesh top size or oversize material, and cyclones deslime and remove the minus 200 mesh material.

 

Dewatering screens are used to remove excess moisture. The resultant minus 200 mesh material is stockpiled on a water decant system which reduces the sand’s moisture content prior to shipping to the customer.

 

The waste wash/process water is directed to a thickener and then to one or more settling ponds. Chemical flocculant is added as the water is discharged into the retention ponds to aid with particle settling. Water used for the wet plant processing is recycled as it is sourced from a lined retention pond. The closed-loop process water circuit provides for efficient use of water as the majority is collected and recycled in the process. Water conservation is a high priority at the operation. The wet plants typically operate 24 hours per day, 7 days per week.

8.3            Production

 

Combined, the OnCore Plants have a nameplate capacity of over 7 million tons of wet 100 mesh frac sand per year based on operating 24 hours a day and nearly 365 days per year. Forecasted production over the expected life of the operations is provided in Figure 8.1, below.

 

 

 

Figure 8.1: LOM Forecasted Processing Plant Production

 

As shown, the OnCore Plants plan to produce just under 7 million tons wet frac sand when all eight plants are active. However, annual finished product volumes will depend on market demand and may fluctuate substantially. The presented LOM production plans are based on Hi-Crush’s controlled (via lease or service agreement) frac sand reserves. Hi-Crush actively investigates additional sand deposits to exploit with their OnCore fleet of mobile processing plants; however, there is no guarantee that additional frac resources or reserves will be available for Hi-Crush to acquire.

8.4            Processing Risks

 

BOYD is unaware of any reported interruptions, outages, shortages, or failures related to processing operations that have materially affected the OnCore Plants. Given the operation is well-established, we believe the risk of such events materially affecting the estimates of frac sand reserves presented herein is low.

 

Based on our review, it is BOYD’s opinion that the processing methods and existing equipment at the plant are sufficient for the forecasted production of finished frac sand products.

9.0            MINE INFRASTRUCTURE

 

9.1            Overview

 

All of the basic infrastructure required for the ongoing operations at the active OnCore sites is in place. Construction or installation of infrastructure at OnCore 2B, OnCore 3B, and OnCore 8 is underway and is planned to be completed before operations commence. Figures 3.1 through 3.6 (pages 3-3 to 3-8) illustrate the general layout of the infrastructure at each of the OnCore operations.

 

Given the size and simplicity of the mining and processing operations at each of the OnCore sites, infrastructure requirements are relatively simple. Each site appears to have the necessary capacity/capabilities to support their respective near-term operating plans. Operational preference may lead to the upgrading of some existing facilities if warranted.

 

BOYD is unaware of any reported interruptions, outages, shortages, or failures related to infrastructure requirements that have materially affected the OnCore operations. Given Hi-Crush’s operational experience and that most of the operations are well-established, we believe the risk of such events materially affecting the estimates of frac sand reserves presented herein is low.

 

9.2            Transportation

 

Each of the OnCore sites is serviced by several roads maintained by the local municipality, county, and state governments. These roads are either paved or well-maintained graded roadways. Road access is available year-round.

 

There is not any rail infrastructure available at any of the OnCore sites. All products are shipped via bulk trucks. Transloading would be required to use existing rail networks. Hi-Crush plans to continue to transport their products from the OnCore Plants via road.

 

9.3            Utilities

 

The OnCore facilities are serviced by three-phase electric power. Substations access 138 kV lines and step voltage down to 12.5 kV lines which deliver power to each the processing plants.

 

JOHN T. BOYD COMPANY

 

9-2

 

The wash process water is recycled after fines are removed via settling with a flocculent in a series of constructed ponds. As the mine progresses, silt ponds are constructed in mined-out areas. Additional makeup water is obtained from wellfields near the plants or purchased from water suppliers.

 

Wastewater from offices and other buildings is collected via holding tanks and disposed of on a regular basis. Potable water is provided by the public water system.

 

9.4             Tailings Disposal

 

The mining and processing of frac sand at each of the OnCore operations creates a substantial volume of tailings (i.e., waste material). These tailings are typically a mixture of clay, very fine sand, and other non-silica minerals. Tailings are typically disposed of in ponds (i.e., former mining pits) where the solid materials settle to the bottom and water is recovered for reuse. As mining progresses, depleted pits will become new tailings disposal sites. Freshwater ponds are maintained on the property so water can be stored after processing through the tailings ponds.

10.0             MARKET ANALYSIS

 

10.1Market Overview and Outlook

 

The Permian Basin’s (Permian) frac sand market is driven by unconventional horizontal drilling in the oil and gas industry. In the late 1990s, rapid advances in horizontal drilling and hydraulic fracturing (fracking) in North America ushered in large-scale commercial oil and gas production. This fracking technique has been increasingly successful and modified over time to extract oil and gas held in dense layers of shale rocks, whose low permeability had previously prevented the flow of hydrocarbons.

 

Hydraulic fracturing uses a mixture of water, chemicals, and proppant (natural sand or man-made sand-like substances) to fracture shale rock and release hydrocarbons such as oil, natural gas, and natural gas liquids. The proppant acts to keep the fractures open (prop) while the pressurized fluids flow back up the well piping. Wells have become more productive with the addition of horizontal drilling capabilities, longer lateral lengths, and multi-stage fracks.

 

North America’s shale oil industry’s growing competitiveness gained through continuous technology improvement and falling production costs have had major implications on the global energy market. Oilfield service companies, including frac sand producers, made significant efficiency gains in 2020 to survive lower commodity prices because of the COVID-19 pandemic. These gains have followed through to the present day.

Figure 10.1, on the following page, illustrates the CME Group’s West Texas Intermediate (WTI) Crude Oil Annual Average Futures Price. We estimate breakeven pricing for unconventional oil wells in the Permian to be in the $30 to $40 per barrel range. 2023 WTI futures estimate pricing to generally be in the $64 to $75 range through 2032. This cost and pricing combination supports positive wellfield economics and thus frac sand consumption.

Figure 10.2, on the following page, is compiled from downloaded and processed publicly available data from the Railroad Commission of Texas (RCC) for horizontal oil and gas permits in the U.S. This data shows a steady increment from the post-pandemic all-time low of 716 permits recorded in the 2nd quarter of 2020, to almost 2,000 permits in the 3rd quarter of 2022. From this period until the 4th quarter of 2023, a slow decreasing trend is shown with an average of 1,600 permits by quarter. It is important to note in this figure that most of the permits are based in the Permian region (with an average of 70% of all permits) followed next by permits in the Eagle Ford region (with an average of 21% of all permits) over the last 4 years.

From the 1st quarter of 2021 to the 4th quarter of 2023, the global distribution by permit type is 76% oil and 24% gas. Permit submissions for horizontal oil and gas wells in the Permian follow the same trend of the U.S. Global Permits which suggests a continuation of strong drilling ahead.

Figure 10.4 was prepared combining data available for the current working rigs by region and the horizontal drilling permits. From September 2020 there is a noticeable and constant increase in the rig counts, reaching an all-time high number of permits since the COVID-19 pandemic in January 2023.

During the previous 52 weeks, rig counts were down approximately 13%. However, the continuous growth through the last three years has led to increased production for both crude oil and natural gas. For the same period, crude oil (barrels per day) and natural gas production (thousand cubic feet per day) in the Permian are up 30% and 24%, respectively.

 

JOHN T. BOYD COMPANY

As figures 10.5 and 10.6 illustrate, Permian daily crude oil production is reaching multi-year highs, while daily natural gas production in the Permian continues to make new records, now standing at 24.1 million cubic feet per day.

The EIA’s Drilling Productivity Report reports that the inventory of drilled but uncompleted wells (DUCs) in all regions have declined 49% since peaking in July 2020 (refer to Figure 10.7 for all U.S. regions, and Figure 10.8 for the Permian). This data dovetails with increased crude oil and natural gas production.

Consequently, with increases in production and well completions, activity at frac sand mines has correspondingly increased throughout the U.S. According to MSHA, operating hours from 1st quarter of 2021 through 3rd quarter of 2023 were up 60% for Permian Basin frac sand mines. This data is presented in figures 10.9 (U.S.) and 10.10 (Permian).

Industry research speculates that total in-basin mine hours, as of 2nd quarter 2023, are at the same level as the 2019 peak. Mine hours serve as a directional indicator that dovetails with previous crude oil and natural gas production and DUC data. Current frac sand production in the Permian is estimated to be in the 60 million to 65 million tons per year range, with fairly well-balanced demand and stable pricing. BOYD anticipates frac sand pricing stabilizing substantially above the pricing used in this report. Additionally, we anticipate continued upward sand consumption in the Permian due to economic and geopolitical influences on energy demand.

 

10.2Historical Sales

 

Primarily, Hi-Crush supplies a range of frac sand products to major oilfield services companies and E&P companies operating in the Permian Basin. In addition to their flagship Kermit Mine, Hi-Crush operates seven smaller, built-for-purpose mobile processing plants and one modular processing facility, collectively referred to as the OnCore Plants. The OnCore Plants exclusively produce wet “100 mesh” frac sand—a damp (i.e., undried) frac sand in the 40/140 to 40/200 mesh range.

 

Recent historical sales data provided by Hi-Crush for the OnCore Plants are summarized in Table 10.1, below.

 

Table 10.1: Historical Sales Data
   Units  2020   2021   2022   2023 
Operating OnCore Plants      1    2    4    7 
Product Sales  000 tons   137    1,004    2,209    4,664 
Average Selling Price  $/ton sold   11.50    12.86    17.00    21.04 

 

Frac sand demand dropped in 2020, as compared to 2019, due to the COVID-19 pandemic. However, recovery began in the fourth quarter of 2020 and continued through 2023. Sales volumes and selling prices for the OnCore Plants’ frac sand have increased year-over-year for the last four years.

 

Hi-Crush has structured long-term contracts with most of its customers outlining volume commitments and, in some cases, fixed pricing. Hi-Crush also services customers on a spot basis where volume thresholds are not set, and orders are serviced on an as-available basis at prevailing market prices. The majority of tons sold from the individual OnCore Plants are delivered to one customer only—especially, when the mobile plant operates on the customer’s land. Historically, the top-five customers by sales revenue account for approximately 93% to 100% of total sales from the OnCore Plants annually.

10.3Market Entry Strategies

 

As an existing producer with a lengthy commercial history and established customer base, it is BOYD’s opinion that market entry strategies are not required for continued sale of the OnCore Plants’ frac sand products.

 

10.4Future Sales

 

BOYD’s projections of sales volumes and frac sand prices for the OnCore Plants are informed by Hi-Crush’s historical operating results, their short-term budget forecasts, and our knowledge of frac sand markets. Forecasted prices are based on sales of 100 mesh finished frac sand products. Our frac sand sales forecast for the OnCore Plants is provided in Table 10.2, below.

 

Table 10.2: Frac Sand Sales Forecast
    Sales   ASP 
Year(s)   (000 tons)   ($/ton) 
 2024    5,625    23.33 
 2025    6,750    23.33 
 2026    6,750    23.33

 Total    47,172      
 Minimum         23.33 
 Maximum         23.33 
 Average         23.33 

 

As previously mentioned, some of the OnCore Plants operate under service agreements to mine, process, and deliver finished frac sand to the landowner—an E&P company. These service agreements are structured long-term contracts outlining volume commitments and, in some cases, fixed pricing. Generally, the service agreements do not preclude the sale of finished frac sand to third parties, as long as contracted volume commitments are satisfied.

11.0             CAPITAL AND OPERATING COSTS

 

11.1Historical Financial Performance

 

All the OnCore Plants operate in a common regional market and are in the same business division within Hi-Crush. Hi-Crush generally accounts for the historical and projected financial performance of the OnCore Plants on a consolidated basis; however, detailed financial records are maintained for each operation.

 

Table 11.1 summarizes the past four years of financial data for the OnCore Plants on a consolidated basis. It should be recognized that: (1) the first OnCore plant (OnCore 1) began operation in 2020, and (2) the COVID-19 pandemic caused severe economic, market, and other disruptions which affected frac sand sales during 2020 and 2021.

 

Table 11.1: Historical Financials
   Units  2020   2021   2022   2023
Frac Sand Sales   000 tons     137    1,004    2,209   4,664
Gross Revenues  $ 000     1,259    12,992    36,368   90,627
Average Selling Price  $/ton sold     11.50    12.86    17.00   21.04
Cost of Goods Sold  $ 000     1,536    11,340    27,947   47,104
Average Cost of Goods Sold  $/ton sold     11.21    11.29    12.65   10.10
Capital Expenditures  $ 000     2,417    4,926    31,573   32,482

 

The total cash cost of goods sold includes operating costs (i.e., mining, ongoing reclamation, processing, product loadout, and other related costs), in addition to selling, general, and administrative expenses.

 

Based on the financial data presented above:

 

·ASP increased marginally from $11.50 per ton sold in 2020 to $21.04 per ton in 2023, averaging $17.62 per ton over the last four years.

 

·ACS has remained relatively consistent, ranging from $10.10 to $12.65 per ton sold and averaging $10.97 per ton sold, over the last four years.

 

·EBITDA margin was positive every year but 2020 (the first year if production) and was 48% in 2023.

11.2Estimated Costs

 

The production and unit cost estimates for the OnCore Plants are informed by Hi-Crush’s historical performance and internal budget forecasts, in combination with BOYD’s familiarity with mining costs at similar operations. Operating volumes are well-defined and understood, as are mining and processing productivities at the OnCore operations. As such, it is BOYD’s opinion that the production and financial projections are reasonable and are likely to be within ±20% accuracy level.

 

This section contains forward-looking information related to capital and operating cost estimates for the OnCore Plants. There are inherent known and unknown risks and uncertainties associated with all mining operations. These risks, uncertainties, and other factors are not quantifiable, but include, but are not limited to, adverse general economic conditions, operating hazards, inherent uncertainties in interpreting engineering and geologic data, fluctuations in commodity prices and prices for operational services, government regulation and political risks, as well as other risks commonly associated with the mining industry.

 

11.2.1Projected Capital Expenditures

 

Projected capital expenditures for the OnCore Plants fall into two general categories:

 

(1) growth or expansion outlays to increase production, and (2) sustaining or maintenance expenses to replace or repair assets to ensure continued production. The timing and amount of these capital expenditures are expected to be largely discretionary and within Hi-Crush’s control.

 

Growth/expansion capital expenditures include allocations for: (1) completion of OnCore 8’s modular processing plant, and (2) sitework to prepare the OnCore 2B, 3B, and 8 sites for operations, and (3) demolition and reclamation of the OnCore 2 and 3 sites. Hi-Crush’s growth/expansion capital expenditure budget for 2024 is provided in Table 11.2, below.

 

JOHN T. BOYD COMPANY

 

 

11-3

 

Table 11.2: Growth Capital
Expenditures Budget for 2024
   Budget 
Project/Site  ($ 000)
Construction/Sitework:     
Oncore 8   20,248 
Oncore 2B   3,385 
Oncore 3B   3,385 
      
Reclamation:     
Oncore 2   829 
Oncore 3   1,781 
Total   29,628 

 

OnCore’s seven mobile processing plants are already in-service and should not require any near-term major capital investment to maintain full commercial production. BOYD projected sustaining capital expenditures at a unit cost of $1.20 per ton sold, this includes maintenance of production equipment, as well as other items, for the operations. This factor is based on our professional judgment and experience with similar operations and reflects the expected life span of the OnCore mobile processing plants and related infrastructure.

 

11.2.2Projected Operating Costs

 

Operating cost estimates were developed based on recent actual costs and considering specific operational activity levels and cost drivers. The estimates consider current and expected labor headcount and salaries, major consumables and unit prices, power costs, and equipment and maintenance costs. The total operating cost estimate includes all site costs related to mining, processing, loading, and general and administrative expenses (including non-income taxes, fees, and royalties).

 

Operating costs for the OnCore operations are expected to remain relatively consistent (on an uninflated basis) with 2023 results. As such, the projected total cash cost of goods sold over the life of the mine averages $11.57 per ton sold over the life of the mine. As the operation is in a steady state, BOYD considers the future operating cost estimates to be reasonable and appropriate.

12.0          ECONOMIC ANALYSIS

 

12.1            Approach

 

The economic analysis presented in this chapter was prepared by BOYD for the purpose of confirming the commercial viability of the OnCore Plants’ reported frac sand reserves and not for the purpose of valuing any of the OnCore operations, or their assets. The economic analysis contains forward-looking information related to the projected operating and financial performance of the OnCore Plants. This projection involves inherent known and unknown risks and uncertainties, some of which may be outside of Hi-Crush’s control. Hi-Crush, as with all mining companies, actively evaluates, changes, and modifies business and operating plans in response to various factors that may affect operational and/or financial results. Actual results, production levels, operating expenses, sales realizations, and all other modifying factors could vary significantly from the assumptions and estimates provided in this analysis. Risk is subjective, as such, BOYD recommends that each reader should evaluate the project based on their own investment criteria.

 

The financial model used for the purposes of the economic analysis forecasts future free cash flow from frac sand production and sales over the life cycle of the OnCore operations using the annual forecasts of production, sales revenues, and operating and capital costs discussed earlier in this report. A DCF analysis, in which future free cash flows are discounted to present value, is used to derive an NPV for the frac sand reserves. The use of DCF-NPV analysis is a standard method within the mining industry to assess the economic value of a project after allowing for the cost of capital invested.

 

The financial evaluation of the OnCore Plants has been undertaken on a simplified after-tax basis and does not reflect Hi-Crush’s corporate tax structure. NPV is calculated using an after-tax discount rate of 10% (NPV10). Cash flows were assumed to occur in the middle of each year and are discounted to January 1, 2024. Cost estimates and other inputs to the cash flow model for the project have been prepared using constant 2023 money terms, i.e., without provision for inflation. The internal rate of return and project payback were not calculated, as there was no initial investment (sunk costs) considered in the financial model provided herein.

 

A suite of sensitivities was calculated to evaluate the effect of the main drivers of economic performance (including variations in sales prices, operating costs, and capital costs).

 

JOHN T. BOYD COMPANY

 

 

12-2

 

It is BOYD’s opinion that the financial model provides a reasonable and accurate reflection of the OnCore Plants’ expected economic performance based on the assumptions and information available at the time of our review.

 

12.2            Assumptions and Limitations

 

Cash flow projections for the OnCore Plants have been generated from the annual forecasts of production, sales revenues, and operating and capital costs discussed earlier in this report. A summary of the key assumptions and limitations is provided below:

 

·Sales volumes of finished frac sand in 2024 are based on Hi-Crush’s budget projections and are expected to remain constant thereafter. Forecasted sales volumes are at or below the capacity of the OnCore processing facilities, both individually and in aggregate.

 

·ROM production requirements are based on an expected processing yields at each property and will remain in line with expected sales volumes. Forecasted ROM production is at or below the capacity of the existing mining equipment and related infrastructure.

 

·Forecasted revenues are based on sales of 100 mesh finished frac sand with a weighted average sales price of $23.33 per ton in 2024 and continuing for the expected life of the reserves (through 2039).

 

·Projected operating costs are discussed in Chapter 11 and include all site costs related to mining, processing, loading, and general and administrative expenses (including non-income taxes, fees, and royalties). Unit operating costs are expected to remain relatively constant over the life of the operation.

 

·Projected capital expenditures are discussed in Chapter 11 and costs for expansion/growth and sustaining/maintenance of operations. Unit sustaining capital expenditures are expected to remain relatively constant over the life of the operation.

 

·Net working capital is not included in the valuation since the OnCore business unit is a going concern.

 

·Current fixed assets are depreciated over remaining life of the operations using their carrying value as of December 31, 2023, and the straight-line method.

 

·Depreciation expenses for new fixed assets are based on a straight-line depreciation calculation using an 8-year (sustaining/maintenance) or 10-year (expansion/growth) asset life.

 

·Income taxes are based on a Federal Corporate Tax Rate of 21%.

 

·Asset recovery/salvage values were not included in the valuation.

 

·Post-mining cost of reclamation is not included in the valuation.

DCF-NPV on a pre-tax and after-tax basis, using discount rates of 8%, 10% (the base case), and 12%, were calculated utilizing the projected cash flows. Table 12.3 summarizes the results of the pre-tax and after-tax DCF-NPV analyses:

 

Table 12.3: DCF-NPV Analysis
   NPV ($ millions) 
   8%  10%  12%
Pre-Tax   332.9    309.6    289.0 
After-Tax   265.2    245.8    228.8 

 

As shown, the pre-tax DCF-NPV ranges from approximately $289 million to $323.9 million. The after-tax DCF-NPV ranges from approximately $228.8 million to $265.2 million.

 

The economic analysis confirms that the OnCore Plants generate positive pre- and after-tax financial results and a real NPV10 of $245.8 million. As such, it is BOYD’s opinion that the OnCore frac sand reserves have demonstrated economic viability.

 

12.4            Sensitivity Analysis

 

Table 12.4, below, shows the sensitivity of the project after-tax for a cash flow discounted at 10% (NPV10) to a variation over a range of 20% above and below the base case in:

 

(1) average selling prices and (2) operating costs.

13.0   PERMITTING AND COMPLIANCE

 

13.1Permitting Requirements and Status

 

Several permits and compliance with federal, state, and municipal regulations are required for mining, processing, and related activities at each of the OnCore Plants. These activities are principally regulated by the Texas Commission on Environmental Quality (TCEQ). The predominant registration requirement is with the TCEQ’s Air New Source Review program for air pollution control. Under this program, each OnCore Plant is issued a permanent “Permit by Rule” registration for operation of the registered wet plant. A summary of the permits and registrations for the OnCore operations is provided in Table 13.1, below.

JOHN T. BOYD COMPANY

 

 

13-2

 

BOYD reviewed the permits and registrations necessary to support continued operations at each of the OnCore Plants. Such required permits appear to be valid and in good standing. The approved permits, registrations, and certifications are adequate for the continued operation of the mining and processing facilities. New permits/registrations, revisions, and/or renewals may be necessary from time to time to facilitate future operations. Given sufficient time and planning, Hi-Crush should be able to secure new permits/registrations, as required, to maintain its planned operations within the context of current regulations.

 

13.2Environmental Studies

 

It is BOYD’s understanding that no standalone environmental studies have been conducted for any of the OnCore sites. As part of the state and federal permitting process, various environmental assessments have been conducted and reviewed by the relevant local, state, and federal agencies. As the necessary permits for mining and processing operations have been issued, it is BOYD’s understanding that all environmental assessments have been accepted by the relevant regulatory bodies and no material issues were found.

 

13.3Waste Disposal and Water Management

 

The coarse refuse generated from the sand processing operations is stockpiled and used in the construction of impoundment or backfilled into previously mined pits. The fine refuse generated from the sand processing operations is disposed of by pumping it into impoundment ponds. Waste disposal facilities are in place for current mining operations, with plans to expand the disposal facilities to meet life of reserve storage requirements.

 

Water control structures are in place and function as required by regulatory agencies.

 

13.4Compliance

 

The OnCore operations are regulated by TCEQ on matters involving air and water pollution and inspected periodically by the state if issues arise.

 

Mine safety is regulated by MSHA. They inspect the facilities a minimum of twice a year. Hi-Crush’s safety record compares favorably with its regional peers.

 

JOHN T. BOYD COMPANY

 

 

13-3

 

Based on our review of information provided by Hi-Crush and available public information, it is BOYD’s opinion that the OnCore Plants’ record of compliance with applicable mining, water quality, and environmental regulations is generally typical for that of the industry. BOYD is not aware of any regulatory violation or compliance issue that would materially impact the estimated frac sand reserves.

 

13.5Plans, Negotiations, or Agreements

 

New permits and certain permit amendments/revisions require public notification. The public is made aware of pending permits by advertisement in local newspapers. Additionally, a copy of the application is retained at the local county’s public library for review. A comment period follows the last advertisement date to allow the public to submit comments to the regulatory authority.

 

BOYD is not aware of any other community or stakeholder concerns, impacts, negotiations, or agreements that would materially impact the frac sand reserve estimate.

 

13.6Post-Mining Land Use and Reclamation

 

Under current regulations, the State of Texas does not require reclamation or remediation of surface mined lands by aggregate (including frac sand) operations. However, OnCore Plants’ lease and work order agreements generally require the following reclamation requirements:

 

·Removal of all structures and equipment.

 

·Refilling or grading of all mining pits to a flat bottom and sides sloped such that livestock or vehicles could easily traverse the property.

 

·Stabilization and landscaping (including reseeding and revegetating) of disturbed areas to prevent water and wind erosion or the discharge of exposed materials off-site.

 

·Disposal of hazardous wastes.

 

As a matter of good mining practice, Hi-Crush seeks to conduct progressive reclamation (per the above requirements) throughout each operation’s mining life to minimize risk and costs at closure.

13.7Local Procurement and Hiring

 

BOYD is not aware of any commitments for local procurement or hiring. Hi-Crush reports making efforts to source supplies and materials from regional vendors. The workforce is likewise located in the regional area.

 

Hi-Crush’s stated core values include making positive impacts in the communities in which it operates. In addition to the payment of income taxes and other local community taxes such as property taxes and royalties, Hi-Crush supports, financially and otherwise, local community endeavors.

14.0    INTERPRETATION AND CONCLUSIONS

 

14.1Findings

 

BOYD’s independent technical assessment was conducted in accordance with S-K 1300 and concludes:

 

·Sufficient data have been obtained through site exploration and sampling programs and mining operations to support the geological interpretations of deposit thickness, grain size distribution, and frac sand quality for the portions of the sand underlying the controlled properties of the OnCore Plants. The data are of sufficient quantity and reliability to reasonably support the frac sand resource and frac sand reserve estimates presented in this report.

 

·BOYD is of the opinion that our data validation efforts: (1) adequately confirm the reasonableness of the geologic interpretations, resource estimation criteria, and economic assumptions; and (2) support the use of the data in frac sand resource/reserve estimation.

 

·The 47.2 million saleable product tons of frac sand reserves (as of December 31, 2023) identified on the property are reasonably and appropriately supported by technical studies, which consider expected geologic conditions, planned mining and processing operations, forecasted product revenues, and operating and capital cost estimates. As such, BOYD is of the opinion that there are reasonable expectations that the stated frac sand reserves for the OnCore Plants are technically, economically, and legally extractable as of December 31, 2023.

 

·To our knowledge, there are no other relevant data or information material to the OnCore Plants that would materially impact or change this technical report summary.

 

14.2Significant Risks and Uncertainties

 

The ability of Hi-Crush, or any mining company, to achieve production and financial projections is dependent on numerous factors. These factors primarily include site-specific geological conditions, the capabilities of management and operational personnel, product sales prices and market conditions, environmental issues, securing permit renewals and bonds, and developing and operating mines in a safe and efficient manner. Unforeseen changes in legislation and new industry developments could substantially alter the performance of any mining company. It is our understanding that Hi-Crush continuously assesses these factors and adjusts operating plans as a matter of course.

 

JOHN T. BOYD COMPANY

 

 

14-2

 

As frac sand producing operations with an established history of commercial success, there is a high degree of certainty for the OnCore Plants under the current and foreseeable operating environment. However, it should be noted that frac sand is generally marketed exclusively to the energy sector which has historically faced more volatility than many other industries.

 

Subject specific assessments of risk are presented in the relevant sections of this report.

 

14.3Recommendations

 

Based on the status of the OnCore Plants, BOYD has no recommendations for additional work relevant to the subject frac sand reserves at this time.
