ITEM 2. DESCRIPTION OF PROPERTIES
Note on New SEC Mining Disclosure Rules
Information concerning our mining properties in this Annual Report on Form 10-K has been prepared in accordance with the requirements of subpart 1300 of Regulation S-K, which first became applicable to us for the fiscal year ended December 31, 2021. These requirements differ significantly from the previously applicable disclosure requirements of SEC Industry Guide 7. Among other differences, subpart 1300 of Regulation S-K requires us to disclose our mineral resources, in addition to our mineral reserves, as of the end of our most recently completed fiscal year both in the aggregate and for each of our individually material mining properties. Readers are cautioned that mineral resources do not have demonstrated economic value. Mineral resources are subject to further exploration and development, are subject to additional risks, and no assurance can be given that they will eventually convert to mineral reserves. Inferred resources have more uncertainty than Measured or Indicated as the estimation parameters assume mineralized continuity over greater distances which may not accurately reflect the actual mineralization.
Summary
The map below shows the locations of our operations and our exploration properties.

GOLDEN CHEST MINE
Figure 2 – Aerial Photo of Golden Chest Mine in February 2020
The Golden Chest Mine (“Golden Chest”) is the Company’s only Production Stage mine and is comprised of an underground mine, an open pit mine, and an exploration property located about 1.5 miles east of Murray, Idaho. The Golden Chest includes 86 patented mining claims (1,322 acres) and 217 unpatented claims (4,300 acres). The open pit mine is permitted with IDL and the Company has posted a reclamation bond for an approved reclamation plan. IDR is the operator and owns 100% of Golden Chest, LLC (owner of the Golden Chest). Production from the Golden Chest and an adjacent Area of Interest is subject a 2% NSR payable to Calibre Mining Corporation (“Calibre” formerly Marathon Gold Corporation). The mineralization occurs as gold-quartz veins associated with an orogenic deposit type. Ore from the Golden Chest is processed off-site at the New Jersey Mill in Kellogg, Idaho. For more information concerning the Golden Chest, please refer to the information set forth under the caption “Individual Properties-MATERIAL OPERATING PROPERTIES” and under the caption “Golden Chest Mine” in this Item 2.
NEW JERSEY MILL
Property Location
The New Jersey Mill is a fully permitted, 360-tonne per day, flotation mill and concentrate leach plant (“CLP”) located two miles east of Kellogg, Idaho, in the Coeur d’Alene Mining District. The CLP is permitted with IDEQ. The mill is located on the same property as the New Jersey Mine, adjacent to U.S. Interstate Highway 90 and easily accessed year-round by local roads. Three-phase electrical power is supplied to the New Jersey Mill by Avista Utilities.
Property Ownership and Operation
The New Jersey Mill is operated by IDR. In 2011, IDR signed a joint venture (“JV”) agreement with Crescent Silver, LLC (“Crescent”) to increase the capacity of the New Jersey Mill. Crescent funded the expansion in return for a 35% interest in JV assets plus the right to process 7,000 tonnes of its ore per month. IDR is the JV manager and retains a 65% interest in JV assets as well as the right to process its own ore at the rate of 3,000 tonnes per month and to allocate unused and excess capacity in its role as manager. The property covered by the JV agreement includes the crushing circuit, grinding circuit, gravity circuit, flotation circuit, CLP, buildings, and surface rights over the patented mill site claim. Unpatented mill site claims are also part of the JV.
Present Condition of Plant & Equipment
Mill Expansion and Crescent Ore Processing
The expansion of the New Jersey Mill was completed in 2012, rendering it capable of processing 360 tonnes of sulfide ore per day to produce a single flotation concentrate. The expansion cost approximately $3.2 million, all of which was funded by Crescent under terms of the JV (Ex. 10.1). The expansion project included the installation of a new cone crusher, a new fine ore bin, new conveyors, a new 2.4-meter by 4.0-meter ball mill, additional flotation cells, a new paste thickener, associated pumps, and a new building.
Current Ore Processing Operations
In October 2016, the Company resumed operations at the New Jersey Mill, processing ore extracted from open pit and underground at the Golden Chest. In 2023, the New Jersey Mill processed 40,128 tonnes at an average head grade of 6.71 gpt gold with 92% gold recovery. Since restarting operations at the Golden Chest in October 2016, the Company has milled a total of 289,368 tonnes at the New Jersey Mill.
The New Jersey Mill recycles process water and utilizes a paste tailings disposal process patented by IDR founder Fred Brackebusch to minimize impacts to the environment. By implementing paste tailings processing methods, IDR can recycle process water and prevent the discharge of process water to surface waters. At full capacity, this method saves more than 50 million gallons of water per year. IDR was recognized as a “Pollution Prevention Champion” by IDEQ in 2014 for its efforts to reduce pollution at the New Jersey Mill. The Company submitted a permit for an expansion of its existing tailings storage facility (“TSF”) which was approved. The expansion has enough tailings storage capacity for at least two years. The Company has begun ordering long lead time items for a tailings filtration circuit at the mill as part of a paste backfill plant at the Golden Chest which would slightly extend the life of the TSF. The Company has also submitted a Closure Plan for its cyanide leach circuit which is under review by IDEQ.
As of December 31, 2023, the Company had a net capital cost of $3,524,099 associated with the New Jersey Mill.
Permit Requirements
The New Jersey Mill has all the required environmental permits to operate currently and into the foreseeable. Some permits may require modification if operating conditions change, but typically these changes can be completed without impeding the milling operation. A summary of the permits held by the Company are found in following table:

RARE EARTH OVERVIEW
Idaho Strategic controls and operates three REE properties known as Diamond Creek, Mineral Hill (formerly Roberts), and Lemhi Pass. The three properties together make up approximately 19,090 acres of unpatented lode mining claims, and one State of Idaho mineral lease, within Idaho’s 70-mile long REE-Th Belt. All three of Idaho Strategic’s properties have seen substantive historic exploration conducted by the USGS in the 1950s, and more recently by the IGS. IDR has completed numerous geologic mapping programs, surface sampling programs, and has completed one drill program and one trenching program to date on its REE land holdings. While each of the three properties IDR controls are early-stage, the Company considers the properties material to its business due to qualitative factors such as the potential for the company’s properties to be advanced toward future production on an unknown timeline, and the potential importance of REE’s in low-carbon technology and national defense technologies, which could see increased demand in the future. To date, Idaho Strategic has not established any known resources or reserves on its REE properties and plans to continue to advance the projects as funding and permitting allows. For more information concerning the Diamond Creek, Mineral Hill, and Lemhi Pass REE properties, please refer to the information set forth under the caption “Individual Properties-MATERIAL EXPLORATION PROPERTIES” and under their respective caption in this Item 2.
Individual Properties – MATERIAL OPERATING PROPERTIES
GOLDEN CHEST MINE
Figure 3 - Golden Chest Mine Location Map
Property and Location
The Golden Chest is a gold Production Stage property comprised of an underground mine, an open pit mine, and an exploration property located about 1.5 miles east of Murray, Idaho, and 115 km east of the city of Coeur d’Alene, Idaho at Latitude 47 o 37’14” North and Longitude 115 o 49’43” West. The Golden Chest includes 86 patented mining claims (1,322 acres) and 217 unpatented claims (4,300 acres). The surface mine is permitted with the Idaho Department of Lands and has posted a reclamation bond for an approved reclamation plan. Surface water monitoring is completed as a condition of the permit. The mine is along Forest Highway 9 and is accessible by several improved dirt roads from the paved highway. A three-phase power line was installed at the property in 2014 with power supplied by Avista Utilities.
Property Ownership
The core of the Golden Chest is a contiguous group of 26 patented claims where all modern mining has taken place to date. The Company owns the rights to both the surface and subsurface minerals on all patented claims at the Golden Chest directly and through its 100% held subsidiary Golden Chest, LLC (“GCLLC”), excluding the Joe Dandy Claim where IDR owns only the subsurface mineral rights. The total patented claim position covers 1,322 acres. As these patented claims are considered private lots, legal access is allowed. Property taxes on patented claims are assessed by Shoshone County each year and IDR has paid the taxes in full.
IDR currently maintains 217 unpatented mining claims covering 4,300 acres. The claims have been filed with the BLM agency and at the Shoshone County Courthouse. Annual maintenance fees are paid to the BLM by September 1, and the Golden Chest unpatented claim fees have been paid and are in good standing.
Production from the Golden Chest and an adjacent Area of Interest is subject a 2% NSR payable to Calibre.
Property History
The Golden Chest was developed in the late 1800’s through the early 1900’s as part of the first gold production from the Coeur d’Alene Mining District. Historical accounts vary, but the district is believed to have produced approximately 300,000 ounces of gold from placer sources. It is estimated that the historic hard rock mining at the Golden Chest (prior to IDR’s ownership) produced approximately 65,000 ounces of gold, primarily from shallow, underground, high-grade veins. The Golden Chest Mine is considered to be the largest historic lode producer of gold in northern Idaho.
Modern exploration of the Golden Chest area began in the late 1970’s with several companies, including Cominco-American and Golden Chest Inc. (“GCI”), targeting gold and massive sulfides. Drill tests by GCI included a 200-foot hole from surface that intersected a 60-foot zone containing multiple low-grade gold-bearing quartz veins.
Newmont Exploration Ltd. (“Newmont”) followed GCI’s discovery by evaluating the veins for bulk mineable potential in the late-1980’s. Newmont drilled 35 shallow reverse-circulation and five core holes. In 2010 and 2011, a JV between IDR and Calibre drilled 18,300 meters of core and published a resource report in accordance with Canadian National Instrument 43-101Standards of Disclosure for Mineral Projects(NI 43-101).
In September 2013, the Skookum Shoot portion of the Golden Chest property was leased to Juniper Mining Company (“Juniper”). Juniper began construction in Q3 2014, spending an estimated $7 to $9 million on mine development and infrastructure, building a modern gold mine that reached production in May 2015. Mining activities continued until September 2015 when Juniper ceased operations and terminated its lease, forfeiting the mine and infrastructure back to GCLLC.
Present Condition, Work Completed, and Exploration Plans
Current Underground Operations
The Golden Chest underground mine is accessed by a primary decline or main access ramp (“MAR”) with a complimentary escape-way incline ramp, and a series of ventilation raises. The primary mining method is underhand drift-and-fill utilizing cemented rock-fill (“CRF”). During 2023, IDR mined a total of 37,780 tonnes of ore at an average grade of 6.36 gpt gold. The ore came from stopes on the H-Vein and Idaho Vein in the Skookum Shoot. The MAR was extended at depth during 2023 to the 778 sublevel which required about 135 meters of ramp development and 100 meters of associated sumps, muck-bays, and raises. Additionally, 435 meters of stope access ramps were completed during the year.
Current Open-Pit Operations
In 2023, IDR finished its open pit mining operation at the Golden Chest which commenced in August of 2016. The Jumbo Pit, which was the last of three pits and was started in 2022, was completed in March 2023. A total of 4,000 tonnes of ore were mined from this pit with 2,350 tonnes mined this year. Since the Jumbo Pit was completed, the Company has focused on mining underground as its only source of ore.
Exploration Plans and Results
Modern exploration, including over 30,000 meters of drilling, reveals six NW-trending ore shoots at Golden Chest that demonstrate strong periodicity, consistent width and spacing, along the Idaho Fault. Most historic production came from the northernmost of these shoots, the Katie-Dora and the Klondike. Current underground mining occurs within the Skookum Shoot and the H-Vein. Excellent exploration potential remains in unmined portions of the northern shoots as well as in the unmined Paymaster and Joe Dandy shoots to the south. During 2022, a total of 6,353 meters of core drilling was completed with drilling at the Klondike, Paymaster, Skookum, Argus, Evans, Ida, and Badger areas. Highlights of the 2022 drilling included drillhole GC 22-212 which intersected 8.77 gpt gold over 9.2 meters in the Klondike area, and GC 22-223 which intersected 16.6 gpt gold over 1.23 meters in the Paymaster area. A majority of the drilling was intended to upgrade and further define mineral resources, however some grassroots exploration drilling also took place in the western portion of the property. A highlight of the grassroots exploration was the discovery of a shallow, broad, low-grade zone at the Argus prospect where AG 22-2 assayed 0.56 gpt gold over 24 meters. The Argus is located about 2.8 kilometers northwest of the active mining area at Golden Chest. During the summer of 2023, an exploration drift 89 meters in length was completed on the southern Jumbo Vein. No high-grade material was encountered, but long-hole drilling is planned to fully explore this area. In the fourth quarter of 2023, a total of 3,740 meters of core drilling (16 holes) were completed at the Golden Chest on the H-Vein and the primary focus was to increase drillhole density enough to upgrade the H-Vein from Mineral Resources to Mineral Reserves which was successful. A highlight of the H-Vein drilling was an intercept in hole GC-23-233 which assayed 18.7 gpt gold over 2.24 meters.
Present Condition of Plant & Equipment
The Golden Chest underground main access ramp was originally developed in 2013 at nominal 4-meter by 4.5-meter cross-section. Additional development by IDR in the MAR has been completed recently. There are several metal buildings on the mine surface constructed from 2012 through 2021 including a core shed with offices, a mine shop, and associated mine dry and warehouse. The mine electrical service is a three-phase, 500 kilo-volt-ampere installation supplied by Avista Utilities.
As of December 31, 2023, the Company had a capitalized development and investment cost of $7,005,353 associated with the Golden Chest.
Geology & Mineralization
Gold mineralization occurs in veins associated with multiple faulting and folding events in the Coeur d’Alene Mining District. The mineralization occurs as gold- quartz veins associated with an orogenic deposit type. The orogenic system at the Golden Chest appears to have an association with igneous rock activity. Hence, the vein deposits may be described as intrusion-related orogenic gold. The principal vein exploited at the Golden Chest in the recent past has been the Skookum Shoot. It is associated with the Idaho Fault and juxtaposes the quartzites of the upper Prichard Formation against finer-grained argillites which is also of the upper Prichard Formation. In mid-2023 after successful drifting on the H-Vein which is approximately 60 meters west of and in the hangingwall of the Idaho Fault, mining was shifted to this vein. The H-Vein occupies the same type of lithologic contrast as the Idaho Vein and is also associated with a fault, the Timberking Fault. The H-Vein has demonstrated significantly higher gold grades than the Skookum Shoot.
Veins occur adjacent to the Idaho Fault both in its footwall, and in its hangingwall where the H-Vein is found. The mineralization occurs in two types of quartz veins, banded and massive. These veins are generally conformable to bedding in the Proterozoic age Prichard Formation. The banded veins, which occur primarily in argillite, contain, pyrite, arsenopyrite, galena, sphalerite, and visible gold. Thicker, massive veins occur in quartzite and contain pyrite, galena, chalcopyrite, sphalerite, scheelite and visible gold.
The table below summarizes the Company’s Mineral Reserves for the past three years. Note that proven and probable reserves were not reported separately for 2021.

| Total Proven and Probable Reserves | 2023 | 127,477 | 6.74 | 3.2 | 93% |
Notes:
| 1. | Classification of Mineral Reserves is in accordance with S-K 1300 classification system. |
| 2. | Mineral Reserves were estimated by Idaho Strategic Resources and reviewed and accepted by the QP’s. |
| 3. | Mineral Reserves are 100% attributable to Idaho Strategic Resources |
| 4. | Mineral Reserves are estimated at a cutoff of 3.2 Au PPM (grams/tonne) |
| 5. | Mineral Reserves are estimated using a 3-year trailing average gold price of $1850/troy ounce. |
| 6. | Mineral Reserves are contained within the H-Vein and Idaho Vein domains which are both located in the Skookum area. A majority of the Reserve is located in the H-Vein. |
| 7. | An average mining width of 3 m was used for the Reserves reporting for the Idaho Vein. |
| 8. | An average mining width of 2.4 m was used for the Reserves reporting for the H-Vein. |
| 9. | Minimum mining width dilution is accounted for in the estimate. |
| 10. | Numbers may not add due to rounding. |
The 2023 Mineral Reserve increased over the previous year because more drill holes were completed through the higher-grade H-Vein which resulted in the conversion from Mineral Resources to Mineral Reserves.
Two cut-off grades are used for stope planning, the go/no-go cut-off and the in-stope cut-off. The go/no-go cut-off represents any material that has the potential to be mined but does not have to be mined as part of the operational plan. The go/no-go cut-off is used for initial stope planning as any given stope or sublevel does not have to be mined and should only be mined if it is economic. The go/no-go cut-off is equation is presented in Equation 1.
Equation 1 go/no-go cut-off
The in-stope cut-off is used when material in a defined stope must be mined to reach higher grades. In this scenario the mining cost is considered sunk and is omitted from Equation 1 as the cost was incurred regardless of the ore/waste determination at the face. Evaluating equation 1 omitting mining cost yields a value of 3.24 gpt which was rounded to 3.2 gpt for the Mineral Reserves.
The table below summarizes the Company’s mineral resources for the year ending December 31, 2023. Resources were calculated by the Company starting on December 31, 2022. An historic resource report was completed by a third party in 2012, but it was not an SK-1300 compliant resource.

The Diamond Creek Project is a REE Exploration Stage property located approximately 13 kilometers (8 miles) north-northwest of the town of Salmon, Idaho. Diamond Creek is operated by IDR and consists of 244 unpatented lode mining claims situated in the Eureka Mining District Lemhi County, Idaho in Township 23N, Range 21E, Sections 2, 3, 10, 11, 14, 15, 23,25, 26, 27,34,35; Township 22N, Range 21E, Sections 1 and 2 (Boise Meridian) and makes up approximately 4,900 acres.
The Diamond Creek Project is located in the central portion of the Idaho REE-Th Belt. The Diamond Creek mineral claims are located on public lands managed by the USFS. The claims require an annual maintenance fee of $165 per claim per year which must be paid to the BLM by September 1 of each year. The claims fees necessary to obtain and hold the mineral rights at Diamond Creek as well as the investments to explore the project are expensed each year that they are paid. Therefore, Diamond Creek does not show on the Company’s books and does not qualify as a Material Property for financial purposes, rather the Company considers Diamond Creek material to its business due to qualitative factors such as the potential for the company’s projects to be advanced toward future production on an unknown timeline, and the potential importance of rare earth elements in low-carbon technology and national defense technology, which could see increased demand in the future. To date, Idaho Strategic has not established any known mineral reserves or resources on the Diamond Creek property.
Idaho Strategic initially staked the mining claims comprising the Diamond Creek Project in April 2020 and added claims to the group in January 2023. The unpatented lode claims are wholly owned by IDR and there are no underlying royalties on the unpatented lode claims.
The Diamond Creek Project was historically prospected for gold, until the 1950’s when U.S. government sponsored country-wide exploration for raw materials related to nuclear power resulted in the discovery of unique thorium and REE mineralization at Diamond Creek by the USGS and the IGS. Several other companies have undertaken minor rare earths exploration programs on the property including one stage of limited core drilling with some notable REE mineralization encountered. Diamond Creek is mentioned in numerous reports including a USGS report written in 1979 by M.H. Staatz.
The REE mineralization at Diamond Creek is found in two types: fracture filling and replacement veins/bodies. The replacement bodies are composed of bright and varied oxides. There are at least eight known veins, and they range in width from 0.15 m to 7.6 m in thickness. Vein widths appear best developed in the metasediments and can be traced on the surface for distances ranging from 33.5 m to 780 m. The known rare earth elements mineralization occurs along a 2-mile stretch of the Diamond Creek Fault. The Project consists of four distinct areas identified from north to south as: Contact, Lucky Gem, Simer, and Frank Burch.
Samples taken by the USGS show total REE oxide contents ranging from 0.59% to 5.5%. Work by the USGS in 1979 reported that three samples cut across one of the larger veins were assayed for gold and contained 0.5, 2.4 and 11.9 grams per tonne Au. Down-dip extensions of these mineralized veins have never been sufficiently tested.
The Diamond Creek Project currently does not contain any facilities on-site. The Project is easily accessible by road for approximately 8 months out of the year by nearly any vehicle and is accessible year-round by properly equipped vehicles. There are numerous well maintained forest service roads which provide access to all four distinct areas of the Project. There is power nearby to the Project including a powerline which runs along U.S. Highway 93 approximately 3 miles from Diamond Creek. Idaho Strategic utilizes a combined shop and office building located in the town of Salmon, Idaho to stage equipment, log and process drill core, house company employees, and conduct all other rare earth exploration activities relating to Diamond Creek.
To date, Idaho Strategic has conducted surface sampling programs and geologic mapping throughout its ownership of the mineral claims from 2020 to present. On November 3, 2022, IDR completed its inaugural 12-hole Diamond Creek drill program which targeted REE mineralization on the northern portion of the Project known as the Contact and Lucky Gem areas. The positive results of the drill program were reported, and highlights from hole DC 22-8 drilled from the Lucky Gem area in the north-central portion of the Project, were reported to include 11.3 meters (m) of 1.3% total rare earth oxide (“TREO”) from 2.9 m to 14.2 m. The drill results included intervals of 1.1 m from 13.1 m to 14.2 m which returned grades of 2.2% TREO. Also discovered in hole DC 22-8 were significant concentrations of niobium. The Company reported 0.7% niobium over 10.1 m from 2.9 m to 13.0 m including the following higher-grade interval of 1.0% niobium over 0.5 m from 9.6 m to 10.1 m. Hole DC 22-8 drilled down dip through the shallow dipping replacement body where mineralization continued for 50.3 meters before the hole was lost.
In addition to the Company’s drill program, Idaho Strategic conducted surface sampling along a 32-meter trench that exposed REE mineralization at the surface during drill pad reclamation at the Lucky Gem drill pad located in the north-central portion of the Project. Vertical channel samples were taken every 1 meter for the first 20 meters of exposure, then every 2 meters for the last 12 meters. The exposed geology displayed evidence of dynamic fluid movement along shears and fracture zones forming both replacement and fracture-filling type deposits.
The results include 32 continuous meters averaging 1.28% TREO, including high values of 2.0% TREO at 8 m and 12 m. In addition to REEs, 12 m niobium mineralization that assayed greater than 0.5% Nb was located between 5 and 16 m.
As part of the Company’s ongoing participation in the Idaho Department of Commerce’s IGEM Program, Idaho Strategic was able to provide approximately sixty 5-gallon buckets of surface material from its Diamond Creek drill pad reclamation efforts to the University of Idaho for their continued studies regarding alternative, environmentally friendly REE extraction and separation methods.
The Company previously obtained all necessary permits to drill the Diamond Creek Project in 2022. After drilling, all reclamation was completed and approved by the USFS. An additional drilling POO has been submitted to the USFS for the 2023-2024 field year. The new POO will expand on the 2022 results at Lucky Gem and Contact areas as well as additional drilling targeting REE mineralization on the southern end of the Diamond Creek Project in the area known as Simer. There is no timeline for drill permit approval or projected timing of work. To date, there has not been a technical report, feasibility study, or resource estimate conducted by Idaho Strategic. The Company has provided a summary of exploration activities in order to provide an overview of Diamond Creek and why the Company views this project favorably. Idaho Strategic has excluded exploration results from this report which either did not return the targeted mineralization, did not aid in providing a brief overview of the Project, or for which the Company has not received the results back from lab testing.
Representative surface outcrop samples collected over time, in the normal course of business and reported by the company, come from geologic outcrops identified during surface reconnaissance and are mapped/recorded by on-site professional geologist. The samples are identified by a “one-of-a-kind” label and bagged for secure “chain-of-command” transport to a certified assay laboratory. Idaho Strategic geologists use the assay results to interpret geologic mapping, geophysics and geochemistry in order to make an informed decision for targeting purposes. The samples that Company geologists determined warranted further analysis were sent for assay to ALS Minerals. ALS Minerals utilized Ore Grade REE analysis (ME-MS81h).
Drill core samples at Diamond Creek were taken from the drill rig to a secure, Company-owned facility prior to logging by Company geologists. The core is then logged and samples for assay are obtained by sawing the core in half longitudinally while trying to ensure a representative sample is submitted to the laboratory for analysis. All the samples that have been publicly released were analyzed by ALS Minerals using Ore Grade REE analysis (ME-MS81h) and reported niobium results were analyzed using Fusion XRF- NB Ore Grade (Nb-XRF10).
MINERAL HILL
The Mineral Hill Project (formerly Roberts) is a REE Exploration Stage property located approximately 48 kilometers (30 miles) northwest of the town of Salmon, Idaho. Mineral Hill is operated by IDR and consists of 109 unpatented lode mining claims situated in the greater Mineral Hill district in Sections 3,4,9,10,11,13,14,15,16,22,23,24, Township 24 North, Range 19 East and makes up approximately 2,200 acres. The Project is located in the northern portion of the Idaho REE-Th Belt. The Mineral Hill mineral claims are located on USPD land, which is managed by the USFS. The claims require an annual maintenance fee of $165 per claim per year which must be paid to the BLM by September 1 of each year. The claims fees necessary to obtain and hold the mineral rights at Mineral Hill as well as the investments to explore the project are expensed each year that they are paid. Therefore, Mineral Hill does not show on the Company’s books and does not qualify as a material Property for financial purposes, rather the Company considers Mineral Hill material to its business due to qualitative factors such as the potential for the company’s projects to be advanced toward future production on an unknown timeline, and the potential importance of rare earth elements in low-carbon technology and national defense technology, which could see increased demand in the future. To date, Idaho Strategic has not established any known reserves on the Mineral Hill property.
Idaho Strategic initially staked the mining claims comprising the Mineral Hill Project in early 2020. Throughout Idaho Strategic’s ownership of the Project, the Company has staked additional claims at its discretion based upon exploration conducted to date. The unpatented lode claims are wholly owned by IDR and there are no underlying royalties.
The Mineral Hill Project and the greater Mineral Hill district was historically prospected for gold and copper in the early 1900’s. In the early 1950’s rare earth mineralization was discovered and documented by Abbott (1954) and Anderson (1958) from the Idaho Geological Survey and Kaiser (1956) with the USGS. Abbott (1954) reported cutting a 2.5-foot sample across the lode at the Robert Lode which returned 21.5% combined rare earth oxides and thoria.
The REE mineralization at the Mineral Hill property is associated with a unique group of igneous rocks known as carbonatites. Carbonatites are carbonate rocks sourced from magmatic origins, with primary carbonate compositions exceeding 50%. The Mineral Hill property contains two of the eight known carbonatite occurrences within the Mineral Hill District. The first carbonatite can be found in a northwest-trending seam which measures approximately 400 meters (1,300 feet) long and 90 meters (300 feet) wide; the second occurrence appears to be a smaller carbonatite plug, measuring about 200 meters in diameter.
The Mineral Hill Project currently does not contain any facilities on-site. The Project is accessible by road for approximately 8 months out of the year via National Forest Road 036 (Indian Creek Road). Idaho Strategic utilizes a combined shop and office building located in the town of Salmon, Idaho, to stage equipment, log and process samples, house company employees, and conduct all other rare earth exploration activities relating to Mineral Hill.
From 2020 to present, Idaho Strategic has conducted surface sampling, geophysical surveys and geologic mapping is select areas of its mineral claims. The Mineral Hill Project has two carbonatite prospects with REE mineralization, the “Upper Roberts” and the “Lower Roberts”, which are located about 500 meters apart. The Upper Roberts occurrence outcrops along a northwest strike for greater than 400 meters and demonstrates high-grade REE mineralization in a number of surface samples. One sample taken by Company geologists returned assays of combined rare earth elements oxide in excess of 34%, including 3% neodymium. The company’s samples show critical REEs like neodymium, praseodymium, and samarium in abundance. Similarly, as with IDR’s Diamond Creek property, REE’s are not the only valuable commodities. Gold and niobium may also be in profitable concentration as by-products. Recent samples collected from the Mineral Hill property, show assays with gold values up to 8.8 grams per ton and niobium as high as 0.50%. Exploration plans include further geologic mapping, sampling, and geophysical surveys in order to prepare the project for its inaugural drill program. The permitting process for a drill program at Mineral Hill is underway and any future drilling activities will be subject to permit approval and funding.
Moving forward, Idaho Strategic plans to advance the Mineral Hill Project by developing drill targets aimed at verifying the extent and grade of the two carbonatites that the Company’s geologists have identified and mapped from the surface. There is no timeline for drill permit approval or projected timing of work. To date, there has not been a technical report, feasibility study, or resource estimate conducted by Idaho Strategic. The Company has provided a summary of exploration activities in order to provide an overview of Mineral Hill and why the Company views this project favorably. Idaho Strategic has excluded exploration results from this report which either did not return the targeted mineralization, did not aid in providing a brief overview of the Project, or for which the Company has not received the results back from lab testing.

LEMHI PASS
The Lemhi Pass Project is a REE and thorium Exploration Stage property located approximately 41 kilometers (25 miles) southeast of the town of Salmon, Idaho and stretches into Montana. Lemhi Pass is operated by IDR and consists of 568 total unpatented lode mining claims situated in the McDevitt Mining District, Lemhi County, Idaho in Township 19N, Range 24E, Sections 1, 2, 11, 12, 13, 14, 24; Township 19N, Range 25E, Sections 4, 5, 6, 7, 8, 9, 10, 15, 21, 22 (Boise Meridian) and in the Bloody Dick Mining District, Beaverhead County, Montana in Township 10S, Range 15W, Sections 20, 21, 22, 27, 28, 29, 34, 35 and Township 11S, Range 15W, Sections 10, 11, 14, 15, PB 38. Additionally, IDR has a mineral lease on 565 acres with the State of Idaho for T19N, Range 25E, Section 16. The Project is located in the southern portion of the Idaho REE-Th Belt and straddles the ID-MT border. The property package is mainly contiguous and makes up approximately 11,990 acres. Approximately 407 unpatented lode claims are situated in Idaho, while the remaining 161 unpatented lode claims are situated in Montana.
The claims fees and lease fees necessary to obtain and hold the mineral rights at Lemhi Pass as well as the investments to explore the project are expensed each year that they are paid. Therefore, Lemhi Pass does not show on the Company’s books and does not qualify as a material Property for financial purposes, rather the Company considers Lemhi Pass material to its business due to qualitative factors such as the potential for the company’s projects to be advanced toward future production on an unknown timeline, and the potential importance of rare earth elements and thorium in low-carbon technology and national defense technology, which could see increased demand in the future. To date, Idaho Strategic has not established any known reserves on the Lemhi Pass Project.
Idaho Strategic initially staked the mining claims comprising the Lemhi Pass Project in October 2021 and have added claims, based upon exploration, to the group in February 2022 and again in January 2023. The unpatented lode claims are wholly owned by IDR and there are no underlying royalties on the unpatented lode claims. The Lemhi Pass mineral claims are located on BLM land and require an annual maintenance fee of $165 per claim per year which must be paid to the BLM by September 1 of each year. The State of Idaho mineral lease has a term of 20 years with an annual rent of $1,695, increased annually by 3%. The State of Idaho mineral lease has a minimum annual royalty of $1,000 years 1 through 5; $2,500 years 6 through 20.
The Lemhi Pass Project was historically prospected for gold and copper until 1949 when its unique geologic setting was recognized by the USGS and the IGS during the U.S. government sponsored country-wide exploration for raw materials related to nuclear power. These campaigns resulted in the discovery of thorium in several areas of Lemhi County, including the REE occurrences in the Lemhi Pass area. Several other companies have undertaken minor thorium-related exploration programs on the property, including historic reports of past thorium production. Lemhi Pass is mentioned in numerous reports including the 2009 USGS Circular 1336 titled “Thorium Deposits of the United States – Energy Resources for the Future?” which features parts of the Company’s Lemhi Pass Project on its cover page.
The Company initially staked the Lemhi Pass Project to target an area with the greatest concentration of known veins where the Lemhi Pass, Dan Patch, and Bull Moose faults intersect or approach one another. REE and thorium mineralization at Lemhi Pass is found primarily in the REE mineral monazite. Monazite is a phosphate mineral and most of the Company’s strongest REE values are associated with phosphorus. The monazite at Lemhi Pass occurs as opaque, subhedral, yellow-green to reddish-brown crystals which are mostly microscopic in size, making it hard to detect with the naked eye. Samples taken by the USGS of 31 vein samples, showed TREO contents ranging from 0.073% to 2.20% Staatz (1972a). IDR sampling in 2023 showed total rare earths assays up to 5% validating Company belief that the Lemhi Pass District is largely underexplored for REE’s; since their discovery in the district was ancillary, to the government’s search for nuclear related fuels in the 1950’s.
The Lemhi Pass Project currently does not contain any facilities on-site. Portions of the Lemhi Pass Project are accessible year-round by properly equipped vehicles. There are numerous well maintained forest service roads which provide further access to the Project; however, those roads are not well maintained during the winter months. There is power nearby to the Project including a regional powerline which runs across the Project. Idaho Strategic utilizes a combined shop and office building located in the town of Salmon, Idaho to stage equipment, log and process samples, house company employees, and conduct all other rare earth and thorium exploration activities relating to Lemhi Pass.
To date, Idaho Strategic has conducted surface sampling, geologic mapping, and trenching programs throughout its ownership of the mineral claims from 2021 to present. Select Idaho Strategic sample and trench results have revealed rare earth grades ranging from 0.67% TREO to 5% TREO from areas of the project that had not been well tested for REE’s in the past.
Moving forward, Idaho Strategic will continue its surface exploration efforts in order to gather enough information to warrant a drill program. The land stewardship in the Lemhi Pass District has areas under both BLM, USFS and State jurisdiction. To date, there has not been a technical report, feasibility study, or resource estimate conducted by Idaho Strategic. The Company has provided a summary of exploration activities in order to provide an overview of Lemhi Pass and why the Company views this project favorably. Idaho Strategic has excluded exploration results from this report which either did not return the targeted mineralization, did not aid in providing a brief overview of the Project, or for which the Company has not received the results back from lab testing.
Representative surface outcrop samples collected over time, in the normal course of business and reported by the company, come from geologic outcrops identified during surface reconnaissance and are mapped/recorded by on-site professional geologist.

The samples that Company geologists determined warranted further analysis were sent for assay to ALS Minerals. ALS Minerals utilized Ore Grade REE analysis (ME-MS81h).
Internal Controls on Exploration and Development Drilling Programs
Exploration and development drilling programs are performed using industry standard quality control methods for drilling, logging, sampling, and analytical procedures. The laboratory used by IDR for sample preparation and analyses is: American Analytical Services, Inc. (“AAS”), located at 59148 Silver Valley Rd, Osburn, ID 83849. AAS is ISO 17025 Certified for Mineral and Ore Chemical Testing. Fire assaying is the only method used to quantify gold in core samples and muck samples. Occasionally Atomic Absorption is use for multi-element analysis.
IDR’s Quality Assurance/Quality Control (“QA/QC”) program has been in place since the GCLLC JV in 2011. The QA/QC program consists of inserting blanks and commercially certified standards into the sample stream. A blank or a standard is inserted into the sample sequence at least every 10 samples. All standards are commercially certified and have been prepared in advance by accredited labs. The QP’s reviewed the results of blank assay and only 2 of 327 samples returned an assay greater than the detection limit for fire assay, 0.060 gpt gold.
For all the samples processed by AAS on behalf of GCLLC/IDR, the following methods were used to obtain a fire assay for gold. Samples received at AAS are sorted and coded. They are then placed in the sample drying room and dried at 60°C. All drill samples are collected from the rig daily by mine staff and transported to the locked and secure mine office/core shed building. Sample security has relied upon the fact that the samples were always attended or locked in appropriate sample storage areas. Samples remain within the custody of staff up to the moment the samples are delivered to the laboratory at which time AAS assumes custody. Chain of custody procedures include filling out sample submittal forms that are sent to the laboratory with sample shipments to make certain that all samples are received by the laboratory.
The sampling methods meet industry standard practices and are adequate for mineral resource and mineral reserve estimation and mine planning purposes. Sampling was conducted by appropriately qualified personnel under direct supervision of appropriately qualified geologists.Sample collection procedures used meet industry best practices. Sample preparation procedures meet industry best practices. QA/QC results produce acceptable results. Security procedures are consistent with industry standards. The databases are managed in a secure area using modern, commonly used software by trained staff. The staff are experienced in the nuances of narrow vein mining and treat the model with their experience in mind.
Drillhole logs are completed using Microsoft Excel and are only accessible by mine technical staff and timestamped at the last time of change. Geologic interpretation and solid modeling are accomplished using Leapfrog. Survey volumes, block modeling, and estimation of Mineral Reserves is accomplished using Maptek’s Vulcan. Data is stored at the mine site and backed up to a separate server stored at the corporate office quarterly.
