Drilling highlighted by drill hole GC 25-336W which intercepted 15.53 grams per tonne (gpt) gold over 4.3 meters (m), reported in drilled thickness

Idaho Strategic Resources (NYSE American: IDR) (“IDR” or the “Company”) is pleased to announce high-grade drill results from its 2025 summer drill program designed to expand on known resources within the Paymaster shoot at the Company’s Golden Chest Mine.

The reported Paymaster drilling is expected to contribute to an increase in IDR’s mineral resources at the Golden Chest Mine. The Paymaster remains open down-dip and along strike following this summer’s drilling program and will continue to be the target of additional infill and resource expansion drilling throughout the winter. The current resource outlined in the Paymaster is located approximately 168 meters south of the Company’s existing underground development, placing the Paymaster near the top of the list as the next area for mine development and eventual production. The drill highlights released in the table below are the result of 3,821 meters of drilling from a single surface drill pad. The drill intercepts are reported in drilled thickness and in grams of gold per tonne:

Both the reported drill results, along with ongoing updates to the Company’s internal Golden Chest geologic model, have significantly increased the Company’s understanding of the Paymaster. Mineralization consists primarily of sulfide-bearing quartz veins (pyrite ± galena, sphalerite, chalcopyrite, arsenopyrite) with free gold sometimes visible in core. To date, the Company has outlined mineral resources in the Paymaster confined within two subparallel veins hosted in the Upper Prichard Formation and spatially associated with a monzonite sill. The veins have a general north-northeast strike and moderate dip to the west. The two Paymaster veins are referred to as the Paymaster Hangingwall Vein and the Paymaster Footwall Vein respectively, in relation to their positioning on either side of the monzonite sill. The Paymaster veins are interpreted to be part of the property-scale Idaho Fault system, similar in style and orientation to the Idaho vein. Drilling during the summer confirmed continuity of mineralization down-dip and better defined the structural corridor hosting the mineralization - the southern boundary of which appears to be controlled by a substantial thickening of the monzonite sill, with higher grade gold mineralization typically encountered to the north, where the monzonite sill is thinner.

Idaho Strategic’s President and CEO, John Swallow commented, “These latest Paymaster drill results underscore the potential of the Golden Chest Mine and our team’s ability to continue to identify and delineate high-grade narrow vein resources near our existing underground workings. Our production-backed exploration business model is functioning as designed and it is always rewarding to see the increased investment in exploration lead to the discovery and delineation of additional mineable ounces. We will continue to take advantage of higher gold prices to reinvest in both our operations and our exploration, setting the stage for continued growth at the Golden Chest Mine and in the broader Murray Gold Belt.”

Idaho Strategic expects to provide its updated resource calculations in the first quarter of 2026 as a part of the updated Technical Report for the Golden Chest Mine filed as an exhibit to the Company’s 2025 Annual Report.

Forward-looking information includes the potential for the reported drill highlights to aid in increasing the Golden Chest’s mineral resources net of depletion in 2025, the potential for the Paymaster shoot to be mined by Idaho Strategic in the future, the potential for the Paymaster shoot to be an economic source of ore, the potential for IDR to continue to drill the Paymaster shoot over the winter, the potential for future drilling to result in additional discoveries, the potential for the geologic model and interpretation of the Paymaster shoot to change, and the potential for additional discovery and delineation of high-grade narrow vein resources near existing underground workings at the Golden Chest. Investors should note that IDR’s claim as the largest rare earth elements landholder in the U.S. is based on the Company’s internal review of publicly available information regarding the rare earth landholdings of select companies within the U.S., which IDR is aware of. Investors are encouraged not to rely on IDR’s claim as the largest rare earth elements landholder in the U.S. while making investment decisions.
