Idaho Strategic announces results of 2023 trenching program at Lemhi Pass

Idaho Strategic Resources announces results of its 2023 trenching program at Lemhi Pass. A total of 1,070 linear feet was divided to construct eight trenches over three prospects. The three historical prospects known as In-Trust, Sparky, and Independence mark the first prospects out of IDR‘s expansive land position to be tested in the district. IDR maintains approximately 11,425 acres of unpatented claims and state lease land at Lemhi Pass. Two of the three In-Trust trenches encountered strong REE mineralization associated with faults. The 13 samples in the table below assay up to 3.28% total rare earths and average 1.5% TREE. Of note, are very strong enrichments of neodymium, praseodymium, samarium, and dysprosium. These elements are used in the manufacture of rare earth permanent magnets and are among the most valued of all the rare earth elements. In the listed assays, the distribution of rare earth elements is 58% Nd, 8% Pr, 8% Sm, and 2% Dy. Incredibly, these four components combined account for up to 76% of the total rare earth element percentage. At Sparky, four samples collected from material during trenching returned the highest published total rare earth elements assay in the Lemhi Pass district to date. These samples, although not in place, are considered representative of the mineralization source below. The trenching was unable to uncover structural features as the site had been historically excavated and reclaimed and the bedrock proved deeper than the excavator limits. The mineralized rock samples from Sparky show yellow-brown to red-brown frothy, boxwork textured rock, flooded with golden brown jasperoidal material. Similar to the results from the In-Trust trenches, the samples from the trench at the Sparky prospect show very strong enrichments of neodymium, praseodymium, samarium and dysprosium,
