Idaho Strategic Samples 23.5% Total Rare Earth Elements at its Mineral Hill Project

COEUR D'ALENE, ID / ACCESSWIRE / July 13, 2023 / Idaho Strategic Resources, Inc. (NYSE American:IDR) ("IDR" or the "Company") is pleased to announce the discovery of 23.5% total rare earth elements (TREE) in a sample taken from the Company's Mineral Hill Project in Lemhi County, Idaho.

The Mineral Hill rare earth elements (REE) project is comprised of approximately 2,000 acres situated in the northern portion of the Idaho REE-Th Belt. The project includes four distinct REE occurrences known as Lower Roberts, Upper Roberts, Lower Lee Buck, and the newly added Phyllis Gross claim group. The target of the Company's latest exploration program at Mineral Hill was to locate and sample a previously reported REE sample from 1954 which reported 21.5% TREEs. The sample was initially reported in a thesis by Fred Sturm (University of Idaho) and then again by Agatin Abbott (Idaho Bureau of Mines and Geology). Sturm's report describes the occurrence as "an individual mass of monazite greater than any other exposed through the region".

After reviewing the two historic reports, IDR geologists located and sampled Sturm and Abbott's monazite occurrence and assay results for sample 98241 showed 23.5% TREEs, confirming the accuracy of the historic work the Company is building upon while providing ample support for the original decision to focus on this area overall.

IDR geologists describe the monazite mass as a 10 centimeter (4-inch) thick, pale-yellow sandy seam enveloped by two distinct carbonatites (Photo 1). The total width of the carbonatites and seam is 0.85 meters (2.5 feet). The hanging wall carbonatite body is greenish colored with large crystals of ilmenite. The footwall side of the monazite seam is brightly colored, red-brown to orange-brown, crystalline carbonatite that assays 7.5% TREE.

Equally as impressive as the overall grade, is the favorable mix of REEs. As indicated in the table above, the more valuable rare earths used in magnet applications, such as neodymium (Nd) and praseodymium (Pr), compose approximately 16.23% of the total reported rare earth elements. Given the favorable mix of individual rare earth elements and the impressive overall TREE grade, IDR plans to send the sample out for additional metallurgical testing, including flotation, gravity, and magnetic separation techniques - and possibly other recovery and/or separation techniques being studied.

IDR's VP of Exploration, Rob Morgan commented, "We always knew this area of Idaho contained carbonatites with exceptional REE grades. The historic information was paramount in refining our regional focus and the decision to first establish these claims back in 2019. We look at the Mineral Hill Project as being ‘centered' on the high-grade REE mineralization of the district with Roberts, Lower Lee Buck and the Phyllis Gross occurrences defining the center of the bullseye. We feel that these are possibly the highest grades to come out of the region (Idaho and Montana), but also stack up quite favorably on a national basis as well."

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 elements 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 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 7,300 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.

In addition to gold and gold production, the Company maintains an important strategic presence in the U.S. Critical Minerals sector, specifically focused on the more "at-risk" Rare Earth Elements (REEs) with an overall land position of approximately 18,030 acres in Idaho's REE-Th Belt. The Company's Lemhi Pass, Diamond Creek, and Mineral Hill REE properties are included the U.S. national REE inventory as listed in USGS, IGS and DOE publications. IDR's Lemhi Pass REE-Thorium Project is also 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 participating in the USGS Earth MRI program.

With an impressive mix of experience and dedication, 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.
