Recent Study Indicates Favorable Rare Earth Elements Mix at Lemhi Pass - Abundant Concentrations of Magnet and Heavy REEs Relative to Many Current and Proposed REE Mines Globally

COEUR D'ALENE, ID / ACCESSWIRE / November 13, 2024 / Idaho Strategic Resources, Inc. (NYSE American:IDR) ("IDR" or the "Company") is pleased to provide an update on its extensive Idaho-based rare earth elements (REE) landholdings, including its plans for the 2025 REE exploration field season focusing on the Company's Lemhi Pass project.

To recap, on November 15th, 2023 IDR announced impressive results from analysis of sampling at two prospects within its Lemhi Pass project (Idaho Strategic's Lemhi Trenching Returns Up to 5% Total Rare Earths - Including Magnet REE Concentrations in Excess of 70%). And as previously stated, the distribution of rare earth elements analyzed was 58% Nd, 8% Pr, 8% Sm, and 2% Dy, with these four elements combined to account for up to 76% of the total rare earth elements percentage.

Idaho Strategic's geologists, among others, speculate the favorable mix of REEs may be due to the substitution of lanthanum (a common lower value REE) for a greater concentration of neodymium as illustrated in many Lemhi Pass samples analyzed to date. While much more work is required (and planned) the Company's initial findings support the potential for favorable project economics moving forward. As part of its ongoing analysis, and ahead of the 2025 work season, the company contracted Alpha Geologic for further study of samples from its Mineral Hill, Diamond Creek and Lemhi Pass projects.

The two charts below depict the percentages of valuable rare earth oxides in samples obtained from the Company's Sparky and In-Trust (IT) prospects at Lemhi Pass. Along with additional samples obtained from Diamond Creek (DC) and Mineral Hill (MH) in order to provide early-stage comparisons to the reported percentage of valuable rare earth elements in other globally significant projects; including the producing Mountain Pass (California), Mt. Weld (Australia), and Bayan Obo (China) REE mines.

Chart #1 measures the ratio of neodymium ("Nd"), praseodymium ("Pr"), dysprosium ("Dy"), terbium ("Tb"), and Yttrium ("Y") compared to the total rare earth oxides for each respective project

Chart #2 measures the ratio of samarium ("Sm"), Europium ("Eu"), and Gadolinium ("Gd") compared to the total rare earth oxides for each respective project
