Idaho Strategic Reports Record First Quarter 2026 Operating and Financial Performance

Highlighted by a 98.97% Increase in Revenue to $14,482,286 and Record Quarterly Net Income of $6,387,992

Idaho Strategic Resources, Inc. (NYSE:IDR) ("IDR", "Idaho Strategic" or the "Company") today announced its consolidated operating and financial results for the first quarter ending March 31, 2026. Consistent with the Company's business plan, IDR maintained its profitability while growing its gold production and reinvesting in near-mine exploration opportunities and capital projects on-site. During the quarter, the Company's geology team finalized its plans for broader exploration work in the 2026 field season focused on both the Murray Gold Belt District and the Idaho Rare Earth Elements-Thorium Belt. Additionally, work continued on the construction of the Company's new Murray Mill, with the completion of the paste backfill circuit and the start of foundation work for installation of the new ball mill. Operating and financial results for the first quarter include:

During the quarter, Idaho Strategic capitalized approximately $960,713 of core drilling at the Golden Chest that informed mine planning and resource confidence largely related to the continued exploration of the Paymaster area; compared to $0 in the comparable period in 2025. Moving forward, it is anticipated that IDR will capitalize a portion of exploration expenses quarterly rather than annually. Management believes this procedural accounting change provides investors with a clearer picture of the Company's financial performance throughout the year.

Idaho Strategic's President and CEO, John Swallow stated, "Our goal for the year was to build on a strong 2025 – and as evidenced in our record first quarter results, the team has met these expectations. From increased production to expanded exploration and drilling programs, our business plan is working as designed. In addition to the two drills dedicated to resource conversion and exploration drilling at the Golden Chest, permitting is in place for drill programs this year at two projects in the Murray Gold Belt (Little Baldy and Niagara) and at two of our REE prospects (Lucky Horseshoe at Lemhi Pass and Cardinal at Mineral Hill) near Salmon.

"We are one of the few junior mining companies that put a mine into production when our industry was out of favor so that we could take advantage of opportunities when the tailwinds arrived. To that end, we followed up our acquisition of Hecla's Toboggan landholdings in Q3 2025 with the execution of a long-term lease agreement on the nearby Niagara project during Q1 2026, adding potentially significant copper-silver exposure to the Company. Both of these additions were essential to consolidating the Murray Gold Belt District and provide the Company with high-quality exploration targets that will last many years into the future."

Golden Chest Highlights for Q1 2026 Include:

• Mined approximately 11,290 tonnes of ore from underground stopes on the H-Vein.
• Completed a total of 193 meters of development in the main access ramp (MAR) and associated workings including an escapeway/ventilation raise. A record total of 4,008 cubic meters of CRF backfill was placed during the quarter.
• Processed a total of 11,290 dry metric tonnes ("dmt") at the Company's New Jersey Mill with a flotation feed head grade of 9.68 gpt gold and gold recovery of 92.1%.
• Some long lead items for the Murray Mill were delivered such as a jaw crusher and a cone crusher, and additional underground mining equipment including two 4-yard LHDs were delivered to the mine during the first quarter.
• An exploration program consisting of surface and underground core drilling was continued during the first quarter at the Golden Chest. A total of 8,700 meters of drilling was completed at the Golden Chest targeting the Paymaster, Red Star, Katie-Dora, and the H-Vein.

Rare Earth Highlights for Q1 2026 Include:

• Finalized exploration plans for the upcoming 2026 field season. The bulk of the Company's REE exploration efforts are planned for high-grade prospects at both its Mineral Hill and Lemhi Pass projects. To support these programs, IDR has retained the support of seasoned REE exploration geologists familiar with the Company and its REE projects.

Corporate Highlights for Q1 2026 Include:

• Executed a long-term lease on the Niagara copper-silver project located in the Murray Gold Belt District. The project hosts a historic inferred resource estimated to contain approximately 150 million pounds of copper and 8.8 million ounces of silver.
