Idaho Strategic Resources announced 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 company's 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 dominant REE mineral is monazite. Monazite is a phosphate mineral and most of company's 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. 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.
