PART I

ITEM 2.PROPERTIES

We are amending and updating Item 2. Properties in this Amendment, to supersede and replace Item 2. Properties in its entirety from our Original Filing.

Our extraction and production operations are conducted entirely in the continental U.S. We produce potash from three solution mining facilities: our HB solution mine in Carlsbad, New Mexico, our solution mine in Moab, Utah and our brine recovery mine in Wendover, Utah. We also operate our North compaction facility in Carlsbad, New Mexico, which compacts and granulates product from the HB mine. We produce Trio® from our conventional underground East mine in Carlsbad, New Mexico. We also have the West facility, which is a conventional underground potash mine that is not in operation and is in care-and-maintenance mode.

We operate Intrepid South located in Lea County in southeastern New Mexico, which is comprised of 21,834 surface acres, 27,868 acres of BLM grazing leases and 10,405 acres of pending State of New Mexico grazing leases. In March 2020, we sold approximately 320 surface acres from our Intrepid South property, reducing our surface acre ownership from 22,154 acres acquired at the time of purchase, to the 21,834 acres we operate today.

We conduct most of our mining operations on properties that we lease from states or the federal government. These leases generally contain stipulations that require us to commence mining operations within a specified term and continue mining to retain the lease.

The stipulations on our leases are subject to periodic readjustment by the applicable state government and the federal government. The lease stipulations could change in the future, which could impact the economics of our operations. Our federal leases are for indefinite terms subject to readjustment of the lease stipulations, including the royalty payable to the federal government, every 20 years. Our leases with the State of New Mexico are issued for terms of 10 years and for as long thereafter as potash is produced in commercial quantities and are subject to readjustment of the lease stipulations, including the royalty payable to the state. Our leases with the State of Utah are for terms of 10 years subject to extension and possible readjustment of the lease by the State of Utah. Our leases for our Moab mine are operated as a unit under a unit agreement with the State of Utah, which extends the terms of all of the leases as long as operations are conducted on any portion of the leases. The term of the state leases for our Moab mine is currently extended until 2024 or so long as potash is being produced. As of December 31, 2022, approximately 14% of our state, federal, and private lease acres at our New Mexico facilities will be up for renewal within the next five years, and 43% of our state and federal lease acres at our Utah operations will be up for renewal within the next five years.

The following tables provide a summary of our mineral resources and reserves. Additional information is provided in the Individual Property Disclosures below.

As noted, we have relatively long-lived proven and probable reserves and consequently expect to conduct limited and focused additional exploration in the coming five years. We plan to drill core holes in areas near our Carlsbad, New Mexico, facility, in order to further define the ore body. Development of the underground mines is expected to be coincident with the continued advancement of ore zones. Development of the solution mine and brine evaporation operations is expected to be enhanced by the drilling of additional wells and flooding of new solution mine caverns. Although not in our current plans, we also have opportunities to rehabilitate the shafts at the currently idled North mine and additional surface infrastructure to accelerate mining of conventional reserves.

Our leased office space in Denver, Colorado, is approximately 26,000 square feet and has a term expiring on January 31, 2025. We lease approximately 1,400 square feet of office space in Albuquerque, New Mexico, which has a term expiring on May 31, 2027.

We believe that all of our present facilities are adequate for our current needs and that additional space is available for future expansion on acceptable terms.

Individual Property Disclosure - New Mexico

Overview

Our New Mexico operations ("IPNM") consists of our HB Solar Solution, East, West, and North Mines and are located in southeastern New Mexico in Eddy and Lea Counties in the Carlsbad Potash District ("CPD"). The location is further defined by the boundary of the Known Potash Leasing Area ("KPLA"). This BLM managed area consists of that part of the KPLA where the co-development guidelines for oil and gas and potash are in effect for federal lands under the 2012 Secretary's Order issued on December 4, 2021. The 2012 Secretary's Order revises and supersedes a previous Order issued in 1986 and corrected in 1987. The 2012 Secretary’s Order does not alter the boundaries of the area. The area also contains state lands that are managed by the State of New Mexico under the New Mexico Oil Conservation Division Order R‐111‐P ("R-111-P"). In general, the stated objective of the 2012 Secretary’s Order and R‐111‐P is to prevent waste of petroleum and mineral resources and maximize the economic recovery of oil, gas, and potash minerals in the area.

The geology of the potash‐bearing beds of the Carlsbad area is well documented. Overall, the potash‐bearing beds may be described as bedded sedimentary rocks, deposited across the Delaware Basin and Northwest Shelf backreef from the Capitan Reef. The Carlsbad area falls within the Delaware Basin, part of the Permian Basin. The Delaware Basin has a maximum width

Table of Contents

of approximately 100 miles and a length of approximately 150 miles, extending from north of Carlsbad, New Mexico, to Pecos County, Texas.

The Permian Age sequence comprises the Ochoan, Guadalupe, Leonard, and Wolfcamp series in order of increasing age. Laterally extensive, evaporite beds containing deposits of halite, sylvite, langbeinite, kainite, carnallite, and other evaporite minerals are found within the Ochoan Series, whose top ranges from a depth of 2,000 feet near the Texas State line to approximately 200 feet below surface north of Carlsbad. Mining occurs in the Salado Formation which contains 12 potash ore zones, of which six have been or are currently being mined.

Sylvinite is currently being mined using solution methods in the 1st and 3rd ore zone. Historically, sylvinite has been conventionally underground mined in the 1st, 3rd, 5th, 7th, and 10th ore zones. Mechanical mining of langbeinite is currently occurring in the 3rd and 5th ore zones at the East Mine. Langbeinite is prevalent in the 3rd and 4th ore zones in the southern part of the Delaware Basin, and occurs mixed with sylvite in the 5th ore zone.

The property includes two operating mines, the East Underground and HB Solution Mines, one idled mine, the West Mine and the North Mine which was shut down in the early 1980’s. The property is located in Eddy and Lea Counties, near Carlsbad, New Mexico.

The two mining methods currently in practice at IPNM are high‐extraction mechanical underground room‐and‐pillar mining and solution mining. Mechanical mining is well suited to bedded deposits. All potash production at IPNM comes from the HB Solar Solution Mine in the 1st and 3rd ore zones. Trio® production is from langbeinite mined using room‐and‐pillar mechanical mining methods at the East Mine in the 3rd, 4th, and 5th ore zones. Historically, potash was sourced from the West Mine 5th, 7th, and 10th ore zones. Approximately 300 people are employed at IPNM.

The IPNM properties are pledged as collateral for our revolving credit facility. As of December 31, 2022 the net book value of our IPNM material properties was $172.3 million. A reclamation bond is currently in place for approximately $4.4 million.

IPNM has all necessary operating permits and is in production, both underground and solution mining, and through permit reporting maintains environmental compliance. Environmental studies are conducted for major project expansions and modifications to any operations. The most recent Environmental Audit was completed in 2015 for the expansion of the HB In Situ Solution Mining project to include the solution mining of the abandoned Amax potash mine. The work referenced the initial Environment Impact Study ("EIS") for the HB In Situ Solar Solution Mining Project EIS.

East Mine and Plant

The East Mine is a high‐extraction, mechanical room‐and‐pillar mine. Potash was the primary product extracted from the mine until mining progressed to the mixed langbeinite and potash ore in the 5th ore zone. The mixed ore was processed into two products: potash sourced from the sylvinite portion of the mixed ore, and Trio® sourced from the langbeinite portion of the mixed ore. The East Mine plant was converted to a langbeinite‐only operation in April 2016 and potash is no longer produced from the East Mine. The maximum productive capacity of the plant is 400,000 tons of Trio® concentrate annually.

There are five active sections within the East Mine, the operations of which consist of a miner and a shuttle car loading onto a belt conveyor. Each mining section produces approximately 240,000 tons of run‐of‐mine ore each year. The long‐range production balanced with sales projections results in a long‐term annual production of 1.2 million tons of ore for 250,000 tons of Trio® annually.

During 2003 and 2004, we modified the East Plant to allow dual processing to recover the K2O value from both the sylvite and langbeinite fractions of the ore. Langbeinite, marketed as Trio®, is recovered using dense media separation and a fine langbeinite recovery circuit. Currently approximately one million tons per year of ore is processed at a rate of 300 tons per hour. The ore is crushed, screened, pulped, and rescreened. Coarse material is forwarded to the dense media separation ("DMS") circuit. The DMS concentrate is water leached, debrined, and dried. We separate the coarse product into the three Trio® products. We recover fine material from the screening process using gravity separation, leaching, debrining, and drying. We upgrade fine material to premium product using pelletization.

HB Mine and Plant

Historical room‐and-pillar mining operations at the HB complex recovered about 70% of the ore, leaving approximately 30% of the ore available for secondary recovery in pillars plus what can be recovered beyond the limits of the conventional mine works. Mining at the HB Solar Solution Mine recovers potash by injecting saturated saline NaCl brine into the old mine works to create underground leach lakes. Over time, the solution enriched with potash is pumped to the surface to solar evaporation ponds. Selective solar evaporation leaves behind a potash‐enriched salt that is collected using scrapers,

Table of Contents

pumped, and processed at the HB Plant. The solution mine comprises six injection wells, five extraction wells, and three monitoring wells.

In 2012, IPNM commenced filling the HB solar evaporation ponds. The extraction brine sourced from the mined‐out areas of the 1st ore zones of the former underground workings of portions of HB Eddy, HB South, HB North, and the HB Crescent, collectively referred to as the HB Mine, contains approximately 21.7% NaCl and 7.0% KCl. The brine is collected and crystallized in 18 solar evaporation ponds. The HB flotation mill processes the harvested potash and salts from the solar evaporation ponds. Following the separation of KCl, the HB Solar Solution Mine also recovers significant quantities of NaCl.

The North Plant provides classification, compaction, quality control, and load‐out services for production from the HB Solar Solution Mine. Belly dump trucks unload HB product into a dump pocket. We then send the material to surge bins. The product is screened, preheated, weighed, and sent to a compactor feed bin. Material is fed to the roll compactor, and resulting flakes are further reduced in size with the subsequent flake breaker and crusher. Product is then screened and sent to the curing dryer and screened once again before being sent to final product storage. The product is shipped to market in trucks or rail cars.

West Mine

The West Mine is a high‐extraction, mechanical room‐and‐pillar mine that was idled in July 2016 and placed in care‐and‐maintenance mode. The mine was last operated in the 5th, 7th, and 10th ore zones.

North Mine and Compaction Plant

The North Mine operated from 1957 to 1982 when it was idled, mainly due to low potash prices and a change in the mineralogy of the readily accessible remaining reserves which negatively impacted mineral processing. Although the mining and processing equipment has been removed, the mine shafts remain open. The compaction facility at the North Mine is where the HB potash product is granulated, stored, and shipped. The North Facility receives compactor feed from the HB Solar Solution Mine via truck and converts the compactor feed to finished granular‐sized product and standard‐sized product.

We anticipate the need to construct a new sylvite processing facility to handle the higher insoluble and higher carnallitic ores that are contained in the 8th and 10th ore zones. A new processing plant is expected to have a plant recovery of 75%, which is supported by the metallurgical test work done on the 10th ore zone ore by Tetra Tech in 2009 in support of Phase 1 of the North Mine Reopening Feasibility Study.

Leases and Permits

We control the right to mine approximately 143,000 acres in New Mexico. Of that acreage, we lease 32,000 acres from the State of New Mexico, 106,000 acres from the federal government through the Bureau of Land Management (“BLM”), and 300 acres from private owners. We own 4,700 surface acres near the mine site, adjacent to the federal and state mining leases. Most mining operations are on properties leased from the State of New Mexico or the federal government. These leases generally contain stipulations that require us to commence mining operations within a specified term and to continue mining to retain the lease. The stipulations on our leases are subject to periodic readjustment by the State of New Mexico and the federal government. Federal leases are for indefinite terms subject to readjustment of the lease stipulations, including the royalty payable to the federal government, every 20 years. Royalty payments equal a percentage of product sales less freight. Most of our leases with the federal government stipulate a five percent royalty rate. However, certain federal leases contain a sliding scale royalty rate of a minimum of two percent and up to a maximum of five percent based on the grade of ore extracted under the lease. In 2022, IPNM paid royalties of $7.2 million to the federal government.

Our leases with the State of New Mexico are issued for terms of 10 years and for as long thereafter as potash is produced in commercial quantities and are subject to readjustment of the lease stipulations, including the royalty payable to the state. Royalty payments equal a percentage of product sales less freight. Our leases with the State of New Mexico stipulate a five percent royalty rate. In 2022, IPNM paid royalties of $2.7 million to the State of New Mexico.

History of Operations

Potash was first discovered in southwest New Mexico in 1925 in Eddy County, New Mexico, in Snowden McSweeney Well No. I on a V. H. McNutt permit near the center of the portion of the KPLA. Commercial potash shipments began in 1931. The mines have had numerous owners beginning with the U.S. Potash Company’s ownership of the West Mine from 1929 to 1956. Intrepid Mining, the predecessor to Intrepid, acquired the mines, excluding the Amax Mine, from Mississippi Potash, Inc. in 2004. Intrepid acquired the lease to the Amax Mine in 2012. A full ownership history for each mine is included in Section 5 of the technical summary report in Exhibit 96.1 to this Annual Report.

Mineral Resource and Reserves Comparison to Prior Year

Table of Contents

We had no material changes in our mineral resource at the New Mexico Property at December 31, 2022, compared to December 31, 2021. Our New Mexico Property mineral reserve product tons at December 31, 2022, decreased from mineral reserve product tons at December 31, 2021, due to 2022 production.

Mineral Resource and Reserves

Overview

We continue ongoing exploration as a part of our operational long‐term planning. Exploration includes the drilling of core holes from the surface and underground, and the collection of channel samples, which are collected as mining advances. We provided Agapito Associates, Inc. ("Agapito") their dataset beginning in 2007. Since that time, we have added multiple data points by reassessing several drillholes. Our potash reserves are also identified from gamma ray geophysical logs in oil and gas wells. We estimate and quantify bed thickness and potash grade with input from 2,928 sample points. Extensive work was completed with geophysical tools in collaboration with the United States Geologic Survey ("USGS") to determine and verify potash grades from gamma logs. The dataset is from oil and gas wells, surface core holes, underground core holes, channel samples, shaft samples, and roof bolt holes. The key sample types include 7,209 drillholes and channel samples and are broken down by mining zone.

The characterization of the hydrogeology was completed for the HB In Situ Solution Mine by AECCOM in 2011 and is included as part of the publicly available EIS. The study confirmed the availability of water for the initial flooding of the solution mines at a pumping rate ranging from 177 to 1,440 gallons per minute.

Mineral Resource

The exploration drillhole and channel sample data were compiled to form the database, which serves as the basis for estimating the resources. As part of evaluating the mineral resource, we evaluated and reviewed the geologic setting and bed assignments. Of the data within the lease boundary, all data points contribute bed thickness, and several have assay information. The geology was modeled using Carlson Software (2020). A basic inverse distance squared algorithm was used with a search radius of ¾ mile to prepare the 100‐foot by 100‐foot grids for bed thickness and grade. The search radius was applied for Measured and Indicated Resources of ¼ mile and ¾ mile, respectively. Where data is dense, the nearest 25 data points were used to assign values for the grid block. The grids were multiplied by each other to compile a grade‐thickness ("GT") grid within the lease boundaries held by IPNM. The base grid was adjusted for each ore type cutoff. Key assumptions and parameters for resource estimation are listed in the tables below.

The classification of cutoff in terms of GT in units of feet-percent was defined in the Secretaries Order dated October 21, 1986 for mechanically mined potash deposits. The criteria are not dependent on thickness or grade, but on the product of the thickness and grade. To evaluate the viability of mining the IPNM mechanically mined resources, a break‐even cutoff GT was established. Inputs to the estimation of the break‐even cutoff analysis are cost of goods sold, product sale price, mill recovery, and nominal grade.

The cutoff for solution mining in flooded abandoned underground potash mines is a function of the grade of the brine being extracted which results in enough product tons to just cover the cost of production. The cutoff grade for resources of abandoned underground sylvinite is not a parameter for use in the estimation of solution mining resources but does establish an operational minimum limit for the brine grade reserves. The solution mining resources are the pillars remaining after mining and the fringe boundary of the mine. Resources could also be unmined ore left behind to provide geotechnical support. An operational limit of the flood elevation establishes the cutoff between resource and reserve for this deposit. When mining using solution methods in proximity to other mines, or other underground mines not within the control of IPNM, the critical factor in establishing a flood elevation is to keep adjoining properties dry or to protect structures such as shafts.

We did not have any material changes to our IPNM mineral resources during 2022. The material assumptions and criteria used for the IPNM mineral resource estimates are discussed in more detail in Section 11 of the Technical Report Summary in Exhibit 96.1 to this Annual Report.

Mineral Reserve

Mineral reserves that are to be mined using mechanical methods are estimated by the application of a detailed mine plan for the measured and indicated resources within the boundaries of the cutoff GT for reserves. The plan sets the basis for the estimation of annual production of product. The income from product sales and the operating and capital costs to mine the resource is fundamental to the cash flow used to establish economic viability.

Mineral reserves that are mined using solution mining methods are not subject to the traditional application of a cutoff grade, and instead operational limitations are considered. An operational limit of the flood elevation establishes the cutoff between resource and reserve for this deposit.

By definition, modifying factors are the factors applied to indicated and measured mineral resources and then evaluated in order to establish the economic viability of mineral reserves. These factors for IPNM include mechanical and solution mining parameters; mineral processing; oil and gas drill islands and well locations; economic cutoff GT; deleterious minerology; and lease boundaries.

Mechanically Mined Reserves

Table of Contents

Economic modeling indicates cutoff grades for reserves at the IPNM East Mine of 43 ft% K2O for langbeinite resource. Modeling also indicates a cutoff of 75 feet-percent K2O for the high‐insoluble sylvinite resources in the 8th and 10th ore zones, which requires the capital investment of a new plant and refurbishment of shafts. A cutoff of 57 feet-percent K2O is indicated for the West Mine sylvinite resources which requires the processing plant, mine equipment, and associated infrastructure to be rehabilitated.

Internal Controls

IPNM has an internal protocol that provides for well‐defined, safe practices. IPNM has standard operating procedures ("SOP's") in place for logging and sampling core from underground and surface core drilling. According to the SOP’s, the geologist uses gamma ray to initially select the sample interval prior to prepping the sample for analysis. The samples are assayed at the on‐site laboratory. The site laboratory has the capability to conduct X‐ray Diffraction ("XRD"), Total Organic Carbon, and flame photometry laboratory techniques. The mineral analysis for all core and channel samples is analyzed with the XRD. A sample of approximately 300–500 grams is collected. The sample is split down to around 100 g and run through a grinding mill to reduce the size down to approximately –100 mesh. A sample is weighed out to five grams and put into a micronizing mill that reduces the particle size to ~10 microns and pressed into a sample holder. The sample is inserted into the instrument and a diffraction pattern is retrieved. The diffraction pattern is then analyzed using the Rietveld refinement software, reporting weight percent of solid mineral in the sample. The sample preparation, security, and laboratory analytical procedures are conventional industry practice and are adequate for the reporting of resources and reserves.

Individual Property Disclosure - Moab

Overview

Table of Contents

The Moab property is in a unique high‐altitude desert landscape formed from the sandstone of ancient seafloors and sand dunes. Elevations range from 3,900 feet (ft) to 4,400 ft above mean sea level. The property is located approximately 20 miles west of Moab, Utah, which is 234 miles southeast of Salt Lake City, Utah. The Colorado River runs north–south along the eastern boundary of the property. The Moab property covers approximately 14,100 acres of land.

Moab’s potash leases include 10,100 acres from the State of Utah and approximately 200 acres from the U.S. through the BLM. Moab owns approximately 3,800 surface acres overlying and adjacent to portions of the mining leases with the State of Utah.

The depositional history of eastern Utah’s vast salt and potash resources begins during the regionally arid Pennsylvanian Period, 330–310 million years ago. An immense block of the Earth’s crust, in what is today western Colorado, was thrust upward to form the Uncompahgre Highlands and identified as the westernmost expression of the Ancestral Rocky Mountains. As is common throughout geologic history, dramatic uplift was coupled with subsidence in an adjoining area. The subsequent topographical basin was inundated by seawater as it subsided. Throughout the Pennsylvanian Period, sea levels rose and fell. With each retreat of the sea, the Paradox Basin, as it is called, became devoid of fresh sea water, allowing the process of evaporation to dominate which resulted in widespread precipitation of chloride minerals. This retreat/inflow cycle is known to have occurred a minimum of 29 times, with each marked by a specific and predictable sequence of sedimentary deposition. This series of depositional cycles is collectively known as the Paradox Formation. Potash is documented to exist in 17 of the 29 cycles, and it is from these formational cycles that commercial production of potash occurs. Of these 17, two are principally targeted by us for commercial potash production: Bed 5 and Bed 9.

Moab commercially produces potash from two zones, referred to as Bed 5 and Bed 9. These beds are part of a thick sequence of evaporite cycles predominantly composed of halite interspersed with sedimentary layers of black shale and anhydrite. Within Beds 5 and 9, the sylvinite is bounded above and below by occurrences of halite. Sylvite and halite are both water‐soluble by nature. By using water already saturated with sodium, it is possible to selectively dissolve a greater amount of the potassium chloride ore.

Table of Contents

Mining at the Moab property is by the solution mining technique referred to as “selective solution mining.” Selective solution mining dissolves only the KCl component of the sylvinite and leaves the sodium chloride component underground. KCl production is a function of brine grade and the well extraction rate and is limited by the solar ponds’ evaporation rate. Brine grade is a function of retention time within each bed.

Mining by solution methods ends with the delivery of the brine to the evaporation ponds. Mineral processing begins with pond sequencing to enhance crystallization of the potash. The crystals remaining in the ponds after solar evaporation are harvested and processed through the mill where the potash is separated from other salts, then concentrated by flotation. The concentrates are then dried, compacted, and screened into premium grades of white potash. We ship the product to market in trucks or rail cars. Both potash and salt products are processed at the plant facility at a rate of 400 to 1,200 tons per day. The Moab property exhibits the normal results of a surface salt-based operation and is in good working condition. A new compaction facility was installed in 2010.

Access to the property is predominantly via state highway 191 and state road 279, locally referred to as Potash Road. A Union Pacific/Denver and Rio Grande Western Railroad rail spur services the property. The nearest town to the Moab property is Moab, Utah (with an estimated population of about 5,250). Salt Lake City, Utah (population of 198,000) and Grand Junction, Colorado (population of 62,000), are located approximately 240 and 120 miles to the west and east, respectively, by road, and are the nearest major industrial and commercial airline terminals. Moab also has a commercial airline terminal with scheduled flights to Salt Lake City and other nearby cities depending on the season.

The nearby Colorado River provides the Moab mining operation with make‐up water under existing water rights with the State of Utah for a water supply of nine cubic feet per second. The Moab mine has been in operation as a solution mine since 1970 and, as a result, has the infrastructure and available personnel. The mining operation is accessible by a paved county road and accessible by rail. Electric power is fed from local utilities to a recently upgraded substation. The local area population is sufficient to support the Moab mine.

The Moab property is pledged as collateral for our revolving credit facility. We have a reclamation bond in place for approximately $5.6 million, which we expect to increase to approximately $7.5 million. There are no other significant encumbrances to the Moab property, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines. As of December 31, 2022, the net book value of our material Moab property was $62.6 million. There are no significant factors and risks that may affect access, title, or the right or ability to perform work on the Moab property. The Moab property holds numerous environmental and other permits and governmental approvals authorizing the operations at the facility.

Leases and Permits

At our Moab facility, we lease approximately 10,100 acres from the State of Utah and approximately 200 acres from the federal government through the BLM. We own approximately 3,800 surface acres overlying and adjacent to portions of acres leased from the State of Utah. These leases generally contain stipulations that require us to commence mining operations within a specified term and to continue mining to retain the leases.

Our lease with the federal government is for an indefinite term subject to readjustment of the lease stipulations, including the royalty payable to the federal government. Royalty payments equal a percentage of product sales less freight. The current royalty rate stipulated in the federal lease is five percent. In 2022, Moab made no royalty payments to the federal government.

Our Moab leases with the State of Utah are for terms of 10 years subject to extension and possible readjustment of the lease stipulations, including the royalty payable to the State of Utah. Our Moab leases with the State of Utah are operated as a unit under a unit agreement with the State of Utah, which extends the terms of all the Moab state leases as long as operations are conducted on any portion of these state leases. Our Moab leases with the State of Utah are currently extended until 2024 or so long as potash is being produced and stipulate royalty rates between 4.25% and 5.00%. In 2022, Moab paid $2.6 million of royalties to the State of Utah.

History of Operations

Texasgulf, Inc. began conventional underground mining began in 1964, but various mining problems caused management to convert to a system combining solution mining and solar evaporation in 1971. Prior to 1970, approximately 6.5 million tons of sylvinite ore was mined and from that, 1.7 million tons of potash produced. Mining was by continuous miners and made difficult by the irregular floor, gas, and high rock temperatures. The height mined was typically eight feet. The dip of the ore was such that maintaining the miners in the seam was difficult. The seam floor rolls and folds resulted in an irregular mine plan with many large areas left unmined as pillars. In some areas, secondary mining resulted in high extraction.

Table of Contents

We purchased the Moab Salt operation in 1999. In 2000, we drilled two new recovery wells to revitalize production from Bed 5. Production from Bed 5 had declined from near 100,000 tons in 1994 to 60,000 tons in 1999. After completion of the two new recovery wells, the brine concentration improved, and production increased to near 100,000 tons in 2001. Maintaining production at or near the target rate of 100,000 tons per year was difficult from Bed 5 because of declining product concentration. It was believed that solution mining over the prior 32 years had solution mined most of the remnant pillars in the old workings and that active solution mining was restricted to the updip faces of the mine ribs.

We evaluated methods to enhance the production rate and resulted in the decision to develop solution mining in Bed 9. Bed 9 is located 800 to 1,000 feet below Bed 5 and is of higher KCl content. Bed 9 had not been solution mined previously, although, some test mining was completed by the prior owners in the late‐1960s. A novel method of solution mining was adopted for recovery of potash from Bed 9. Moab Salt‐27 and Moab Salt‐28 were drilled “horizontally” in 2002 in Bed 9 to connect and provide pathways for the liquor injected in Moab Salt‐27 to contact the sylvinite and differentially dissolve the sylvite before being lifted from Moab Salt‐28. Currently, Moab Salt‐29 connects Moab Salt‐27 and ‐28 and serves as an alternative to Moab Salt‐27 for injection.

Mineral Resource and Reserves Comparison to Prior Year

We had no material changes in our mineral resource at the Moab Property at December 31, 2022, compared to December 31, 2021. Our Moab Property mineral reserve product tons at December 31, 2022 decreased from mineral reserve product tons reported at December 31, 2021, due to 2022 production.

Mineral Resource and Reserves

Overview

The ore resource model created from the exploration and sampling database in 2007 serves as the basis for this evaluation. Personal inspection of the properties has occurred over the years by Agapito personnel. The most recent inspection by Agapito took place on May 17, 2021. The inspection began with a tour of the tailings lake then the solar evaporating ponds. In addition, the injection and extraction wellfields, processing plant, product packaging and shipping areas were all inspected. During the site visit, harvesting was occurring, and the plant was operating. The plant is typically idle during the peak evaporation season from June 1 to September 1.

Mineral Resource

The property was evaluated using exploration drillhole and channel sample data to form the database that serves as the basis for estimating the resources. The geologic setting was evaluated, and zone assignments reviewed. All the core holes used in this resource estimation report both bed thickness and grade values that lie within the mine lease boundary. As an exception to this, the two potash exploration Wells 28 and IPI‐037, which report bed thicknesses with no assay data, are included in the resource estimate for thickness modeling.

The rationale for the measured, indicated, and Inferred limits is based on industry practice in the potash industry. Measured resources are within ¼ of a mile (1,320 feet) of a hole, conveying the highest level of confidence. In addition, the indicated resources are selected to be within ¾ of a mile (3,960 feet) of a hole and the inferred resources are selected to be within 1½ miles (7,920 feet) of a hole. Indicated tons exclude measured tons, inferred tons excludes the indicated and measured tons. This convention is considered reasonable for the geologic characteristics of the Cane Creek potash deposit.

The mineral resource for the Cane Creek Mine was estimated using Carlson Software 2020 ("Carlson 2020"), a commercially available geology and mine modeling software package. The resources within the property were segregated in the model into 100‐feet by 100‐feet blocks. The resource estimates included in this report are based on the 2018 modeling.

A deterministic estimate of the potash mineral resource was made using the inverse distance squared method. Invoking the theory that closer samples should be better predictors than those further away, the method assigns weights to samples inversely proportional to the separation distance between the estimation point and the sample point. The inverse distance squared method is useful for providing unbiased estimates of the overall resources.

The block grade and heights were generated within a 1.9‐mile search radius. The 1.9‐mile search radius was selected to capture more than one core hole in estimating block values in the areas of interest. The maximum number of drill holes for block estimation was limited to the 20 nearest drill holes. Inverse distance squared behaves as an exact interpolator. When calculating a block value, the weights assigned to the data points are fractions, and the sum of all the weights is equal to 1.0. An average unit density of 130 pounds per cubic foot was used to convert in‐place volume to tons. NaCl (salt) is not reported.

The proportion of the mineral deposit that is considered a resource depends on the following key factors: deposit thickness, deposit grade, and geologic factors. Areas where a bed thickness and potassium oxide (K2O) grade do not meet a 3‐foot and 18.95% K2O cutoff are excluded from the resource. The minimum thickness cutoff is used because sufficient recovery

in thin beds by selective solution mining has not been demonstrated and because of difficulties in locating/maintaining horizontal holes within the bed. The grade cutoff is used because of the difficulty in selective mining in beds with less than 30% KCl content (18.95% K2O).

The gross in‐place sylvinite tonnage for each resource block was calculated by multiplying the net area of the block by the thickness of the bed and the density. The Measured, Indicated, and Inferred Mineral Resource tonnages were estimated within the prescribed radius from the sampling location.

The mineral resources for Bed 5 have been estimated using the end of year 2018 geologic model. Measured, Indicated, and Inferred resources were estimated by sampling blocks within a 1,320‐feet, 3,960‐feet, and 7,920‐feet radius of influence, respectively, from a sample location (drill hole).

The resource estimate for Bed 9 is based on cored intervals and assay data from 21 holes (19 with grade and thickness). A similar methodology used for the Bed 5 resource estimation was used in the resource estimate for Bed 9.

Mineral Reserve

Mineral reserves that are mined using solution mining methods are not subject to the traditional application of a cutoff grade but instead of operational limitations. By definition, modifying factors are the factors applied to a mine plan for the indicated and measured mineral resources and then evaluated in order to establish the economic viability of mineral reserves. The factors for Moab are solution mining parameters, mineral processing, and lease boundaries are shown below.

The reserve estimate is based on a mine plan developed for the Cane Creek Mine. The estimate is based on the geologic model and assigned thicknesses and grades for the flooded old mine workings updip boundary (Bed 5) mapped to the decline curve and the individual caverns (Bed 9).

The mine plan for Bed 5 was determined using a study developed to estimate the area of reserves that have been depleted through solution mining inside and around the perimeter of the old mine workings, with the exception of a large pillar within the perimeter. As such, this perimeter area has been excluded from the reserve estimates for Bed 5. Reserves were estimated for updip and horizontal areas outside of the perimeter. The mineral reserves were estimated as the difference between the reserves from the resource area and the net KCl tons extracted since 2001.

Table of Contents

Although Bed 5 resources can be solution mined with additional horizontal caverns, the reserves estimate only focuses on the net reserves remaining in the old mine as the planned horizontal caverns in Bed 9 are more than enough to support the required mine life for this report.

The mine plan for Bed 9 includes the three existing operating caverns and three additional planned caverns. Estimate of the reserves within the current and future well system area use grade and thickness drillhole data and production to date. No estimate was made of the ore tons, average thickness, and average grade for the previously solution‐mined areas from Bed 9, only the equivalent tons of K2O and KCl were estimated. To date, about 830,000 tons of KCl have been mined from Bed 9. The modifying factors required to convert the in‐place tons into reserve tons are the same as those listed for Bed 5 with the exception of the dissolution factor. The Bed 9 dissolution factor was estimated using a concentration of 7.42% KCl by weight.

Individual Property Disclosure - Wendover

Overview

The Wendover operation is located near the Nevada-Utah border along the western edge of Utah’s Great Salt Lake Desert and is situated within the Bonneville Salt Flats ("BSF"). The BSF is an enclosed-subbasin that contains 150 square miles of salt crust. Because the basin is closed topographically and has no outlet, loss of water is ultimately through evaporation. The BSF was formed through the prolonged accumulation of evaporite minerals in conjunction with periodic lacustrine events. There are three aquifers known to exist beneath the BSF, in descending order, the shallow-brine aquifer, the alluvial-fan aquifer, and the deep-brine aquifer. We produce potash from the shallow-brine aquifer and the deep-brine aquifer. The climate in western Utah is arid with low precipitation and low relative humidity. Average rainfall is five inches and average evaporation is eighty inches.

We produce potash at the Wendover facility through solar evaporation of naturally occurring brines collected from the sedimentary basin adjacent to the processing facility via brine collection ditches and extraction wells. The potash content of the collected brine is concentrated by solar evaporation in a series of ponds to the point that solids are precipitated and can be collected. The precipitated solids are primarily sylvinite, a combination of NaCl and KCl. Harvested solid salts are hauled to the processing facility, where grinding and flotation processes are used to concentrate KCl. The concentrate is then leached with freshwater to remove most of the remaining NaCl. KCl is then dried, sized, and stored for shipment. Potash, NaCl, MgCL2, and metal recovery salt are shipped by truck and rail via Interstate 80 and the Union Pacific Railroad.

The Wendover potash operation is located in the westernmost part of Tooele County, Utah. The plant facilities and offices are located approximately three miles east of Wendover, Utah, on old US Highway 40. The site is approximately three miles east of the Nevada border and is primarily located south of Interstate 80, although portions of the site are located north of Interstate 80. The area of the Wendover mine operation is shown below. The facility, collection ditches, and evaporation systems cover approximately 90,300 acres (approximately 141 square miles). The majority of the ditch collection system is located to the south and east of the processing facilities.

Table of Contents

A robust set of infrastructure is in place for Wendover. Natural gas, electricity, and water have historically been readily available and are expected to continue into the future. Process materials are readily available in the greater Salt Lake Area. All infrastructure for the operation is located approximately three miles east of Wendover, Utah, on old US Highway 40. Interstate 80 bisects the property. The Union Pacific Railroad runs next to the operations. The majority of personnel live and work in Wendover, Utah or West Wendover, Nevada, approximately three to six miles from the operation. The Wendover Airport is located near the operations, although most commercial flights serve the Salt Lake City Airport, which is approximately 115 miles from the operation.

We have operated the property continuously since 2004. The property exhibits the normal results of a surface salt-based operation and is in good working condition. We installed a new compaction facility in 2010, and a new product warehouse in 2012. We use monitoring wells drilled in October 2005 to evaluate brine quality in the shallow-brine aquifer.

The Wendover property is pledged as collateral for our revolving credit facility. The only other significant encumbrance is a reclamation bond of $8.9 million to cover the cost of site reclamation. There are no other significant encumbrances to the property, including current and future permitting requirements and associated timelines, permit conditions, and violations and fines. As of December 31, 2022, the net book value of our material Wendover property was $41.0 million. There are no significant factors and risks that may affect access, title, or the right or ability to perform work on the property. Wendover holds numerous environmental and other permits and governmental approvals authorizing the operations at the facility.

Leases and Permits

We own approximately 57,500 acres of the Wendover site. The BLM and the State of Utah own approximately 32,800 acres of the Wendover site, which we lease (excluding lands used for highway and utility purposes).

We hold leases from the federal government that include 24,700 acres adjoining the Wendover property to the east. Our Wendover federal leases have an indefinite term subject to readjustment of the lease stipulations, including the royalty payable to the federal government.

stipulated in the federal leases is three percent. In 2022, Wendover made $0.3 million in royalty payments to the federal government.

The State of Utah owns several state land trust sections within the Wendover property site boundaries. We lease approximately 8,100 acres of property from the State of Utah under special use and mineral leases. The Wendover state leases are interspersed among our property and the Wendover federal leases. The Wendover state leases are for an indefinite term subject to readjustment of the lease stipulations, including the royalty payable to the State of Utah. Royalty payments equal a percentage of product sales less freight. The current royalty rate stipulated in our Wendover state leases is four percent. In 2022, we made $0.1 million in royalty payments to the State of Utah.

History of Operations

The Bonneville area was recognized in the early 1900s as a source for potash. The original operation was known as the Salduro Works, which operated until 1918 and then closed due to a decline in potash demand. The original Salduro Works was responsible for acquiring lands on which a system of collection ditches was constructed. In the mid‐1930s, Bonneville Limited acquired more land to the west of the original property and constructed primary harvest ponds and additional infrastructure to support the mining operations. Between 1961 and 1963, various potash leases were acquired from the federal and state governments. Kaiser Aluminum & Chemical Corporation acquired Bonneville Limited in 1963. The property, including the ponds, processing operation, and lease land, was acquired by Reilly Industries, Inc. from Kaiser Aluminum & Chemical Corporation in 1988. Intrepid acquired the property from Reilly Industries, Inc. in April 2004.

Mineral Resource and Reserves Comparison to Prior Year

We had no material changes in our mineral resource at the Wendover Property at December 31, 2022, compared to December 31, 2021. Our Wendover Property mineral reserve product tons at December 31, 2022 decreased from the mineral reserve product tons reported at December 31, 2021, due to 2022 production.

Mineral Resource and Reserves

Overview

The ore resource model used to determine resources and reserves was created from a database of brine sampling data in 2007 and include brine sample from the active mining horizon. Agapito has previous completed reserve estimation and analyses under SEC Guide 7, including personal inspection of the property. The most recent inspection was on May 19, 2021 and included the potash plant, evaporation ponds, wellheads, and ditches.

No traditional drilling exploration has taken place in Wendover. We monitor KCl grade from 27 wells that were drilled in October 2005. We sample these wells at least yearly to evaluate brine quality in the shallow-brine aquifer. Samples are evaluated at the on-site lab with full analysis capabilities, including X-ray fluorescence. Additional information on exploration can be found in Section 7 of the technical summary report in Exhibit 96.3 to this Annual Report.

Mineral Resource

Estimates for potash resources were based on KCl brine concentration, porosity, and aquifer thickness from historical reports and brine monitoring data. Cutoff grade assumptions are based on historic cost data sourced from operations. Product sales prices used in the cutoff grade analyses is based on historical sales and marketing results and forward-looking pricing provided by Intrepid marketing and compared to third party sources.

Resource estimates for shallow-brine aquifer were based on the difference between historic well data collected between 1965 and 1967 and current monitoring data with consideration of the cutoff grade. There has been no change in trend of KCl grade to the primary pond or in potash production with brine grade held steady at approximately 0.97% for 58 years without declining.

Resource estimates for the deep-brine aquifer were based on current deep-well draw-down, pumping rates, and historical brine concentration variations. This resource is classified as an indicated resource due to the hydrological uncertainty of the aquifer and is expected to support production for at least 25 years.

Additional information regarding the methodology and key assumptions used to calculate the Wendover mineral resource can be found in Section 11 of the technical report summary in Exhibit 96.3 to this Annual Report.

Mineral Reserve

Key assumptions for the mineral reserve estimates include KCl grade, thickness, geometry, and hydrogeological properties of the aquifer, presence of geologic anomalies that distort the aquifer, impurities that impact solubility or the surface concentration, separation, crystallization, or packaging process, and the cost of goods sold and estimated final price of the product. Due to its history of operations, infrastructure is mature and the processing and cost factors are well understood. Recovery estimates are based on past, current, and anticipated future performance and supported by laboratory or metallurgical testing of the plant feed.

Internal Controls

Our Wendover operations have internal quality assurance and quality control procedures for sample collection. Monitoring wells are sampled at least yearly to evaluate brine quality in the shallow-brine aquifer. During the evaporation season, we collect daily brine samples at brine advancement points. We sample brackish ponds and transfer pumps weekly. We evaluate samples at an on-site lab with full analysis capabilities, including X-ray fluorescence.

ITEM 9A.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures." Our disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. Our disclosure controls and procedures are also designed to ensure that this information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures as of December 31, 2022. The Company's management originally concluded that the Company's disclosure controls and procedures were effective as of December 31, 2022. Solely as a result of the changes made or omitted from the mining disclosures as described elsewhere in this Amendment, the Company's management, including our principal executive officer and principal financial officer, reconsidered their evaluation and concluded that the Company's disclosure controls and procedures were not effective as of December 31, 2022 regarding the mining property disclosures. Because the amended disclosures do not affect our financial statements there is no change to the conclusion of the effectiveness of our internal control over financial reporting as of December 31, 2022.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate "internal control over financial reporting." Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2022, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013.

Based on the results of our evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2022.

The effectiveness of our internal control over financial reporting as of December 31, 2022, has been audited by KPMG LLP, our independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended December 31, 2022, that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive officer and principal financial officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within Intrepid have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
