Idaho Strategic Locates Greater than 4% TREO's - Including Over 2.5% Neodymium - From Exploration at Lemhi Pass

Rhea-AI Summary

Idaho Strategic Resources (IDR) has reported significant findings from its 2022 exploration program at the Lemhi Pass District, where surface outcrops exceeding 4% Total Rare Earth Oxides (TREOs) were located. This discovery effectively doubles previous maximum assay values of 2% recorded by state and federal agencies. Notably, neodymium constituted a substantial component of the TREO values, with samples showing 4.26% TREO at Prospect #2 and 2.35% at Prospect #3. The company has also expanded its land holdings to approximately 7,600 acres. Industry experts believe this area holds substantial untapped potential for rare earth elements (REEs).

Positive

• Discovery of surface outcrops with TREO exceeding 4%, doubling previous assay values.
• Expansion of land holdings from 4,400 acres to approximately 7,600 acres.
• Significant neodymium content in samples, with one sample showing 2.5% neodymium contribution.

Negative

• None.

COEUR D'ALENE, ID / ACCESSWIRE / January 18, 2023 / Idaho Strategic Resources (NYSE American:IDR) ("IDR" or the "Company") is pleased to announce the locating of surface outcrops with greater than 4% Total Rare Earth Oxides (TREO's) during its 2022 exploration program at Lemhi Pass.

In the well-studied Lemhi Pass District, previous state and federal agency work have shown maximum REE assay values as high as 2%. These new IDR sample results are significant because they essentially double the previously known upper end of assay values as published in the USGS, IGS and other references. These latest assays lend validation to our 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.

IDR's Vice President of Exploration, Rob Morgan commented, "Lemhi Pass continues to impress us. It is very encouraging to see samples having half of their total rare earth element content coming from neodymium; located in similar geological settings and covering 1.5 miles in length. Many of our prospects in the area lie on or near the Lemhi Pass Fault, which suggests the district may have some REE mineral zonation associated with this regionally significant fault."

The listed samples were gathered from four different prospects within IDR land holdings; and are from the northern part of the Lemhi Pass District. One sample from Prospect #2 assayed 4.26% TREO; with 2.5% of that value contributed from neodymium alone. Likewise, another sample (Prospect #3) contained 2.35% REE; with 1.21% coming from neodymium.

In Table 1 below, individual amounts of the REE elements are shown. Note the strong neodymium, praseodymiumand samarium.

Table 1: Lemhi Pass samples showing rare earth elements plus yttrium and scandium for TREO.

The dominant REE mineral is monazite. Monazite is a phosphate mineral and most of our strongest REE values are associated with phosphorus. This mineral 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. Gangue minerals associated with REE mineralization include quartz, pink microcline, and iron oxides; such as specularite and limonite.

Lemhi Pass is at the southern end of the 70-mile REE-Th Belt, a northwest trending zone that possesses most of the REE lode occurrences in Idaho (Figure 1). The company has claimed a large number of the known REE occurrences at Lemhi Pass, which may prove to be one of the most prospective REE areas in the US. In 2022, IDR increased its land position from around 4,400 acres of unpatented claims to approximately 7,600 acres of unpatented claims; and an additional 600+ acres of leased state land.

Idaho Strategic's President and CEO John Swallow concludes, "It has been awesome to watch Rob and Becky break down the area from general to specific, with an eye toward exploration that only comes from the specialized experience gained from actual mineral production. We are fortunate to have the perfect mix of generational knowledge, academia, and economics within this project. And while it is still early, in my opinion this has the earmarks to be a standard of the REE industry not only for the Salmon region, but for the state of Idaho as well.

The topography of the Lemhi Pass area makes it a favorable region for mineral extraction; with numerous prospects potentially feeding a conceptual centralized processing plant. In-situ mining methods, where earth moving and surface disturbance are minimalized, are being discussed for both Diamond Creek and Lemhi Pass. Bioleaching, using organic bacteria as an alternative processing technique, is being tested on mineralized material from Diamond Creek as part of the IGEM project."

About Idaho Strategic Resources, Inc.
Domiciled in Idaho and headquartered in the Panhandle of northern Idaho, Idaho Strategic Resources (IDR) is one of the few resource-based companies (public or private) possessing the combination of officially recognized U.S. domestic rare earth element properties (in Idaho), the largest known concentration of thorium resources in the U.S., and Idaho-based gold production located in an established mining community.

Idaho Strategic Resources maintains an important strategic presence in the U.S. Critical Minerals sector, specifically focused on the more "at-risk" Rare Earth Elements (REE's) and Thorium. With over 11,000 acres of Rare Earth Element landholdings, the Company is the second largest REE landholder in the U.S. The Company's Diamond Creek and Roberts REE properties are included the U.S. national REE inventory as listed in USGS, IGS and DOE publications. IDR's Lemhi Pass Thorium-REE Project is recognized by the USGS and IGS as containing the largest concentration of thorium resources in the country. All three projects are located in central Idaho and are participating in the IGEM Program and the USGS Earth MRI program.

The Company produces gold at the Golden Chest Mine located in the Murray Gold Belt (MGB) area of the world-class Coeur d'Alene Mining District, north of the prolific Silver Valley. With over 7,000 acres of patented and unpatented land, the Company has the largest private land position in the area following its consolidation of the Murray Gold Belt for the first time in over 100-years.

With an impressive mix of mining and business experience, the folks at IDR maintain a long-standing "We Live Here" approach to corporate culture, land management, and historic preservation. Furthermore, it is our belief that successful operations begin with the heightened responsibility that only local oversight and a community mindset can provide. Its "everyone goes home at night" policy would not be possible without the multi-generational base of local exploration, drilling, mining, milling, and business professionals that reside in and near the communities of the Silver Valley and North Idaho.
