Inomin Drills Strongest Interval to Date at South Zone Significantly Expanding Critical Minerals Discovery

The December 4, 2025 news release provides the second batch of analytical results from the 2025 diamond drilling program at the Beaver-Lynx project's South Zone. The release highlights results from three holes: B25-04, B25-05, and B25-06. The key intercept reported is in hole B25-06, which returned 204 metres grading 0.20% nickel (Ni), 0.011% cobalt (Co), 0.35% chromium (Cr), and 23.83% magnesium (Mg). The company notes this is the strongest interval to date, significantly expanding the mineral footprint. President John Gomez states the results demonstrate the South Zone's potential for large, bulk-tonnage style mineralization. Results for the remaining seven holes of the 13-hole program are still pending. The exploration program is funded by earn-in partner Sumitomo Metal Mining Canada Ltd.

This news is materially positive as it builds upon and improves the initial results from the same drill program announced on November 26, 2025.

• Confirmation and Expansion: The grades are highly consistent with the first three holes (which averaged ~0.19% Ni), confirming the uniform nature of the mineralization. Crucially, hole B25-06, with a 204-metre interval, is the longest reported from the program so far, supporting the company's thesis of a large, bulk-tonnage system.
• Partner Validation: The program is fully funded by Sumitomo Metal Mining Canada, a major mining company. Positive, consistent results like these increase the likelihood that Sumitomo will continue to fund exploration and complete its earn-in, which is the single most important de-risking factor for Inomin.
• Progression: The company is systematically executing its exploration plan. They announced the program's start (Aug 27), completion (Nov 4), and are now delivering results in batches (Nov 26, Dec 4). This steady flow of positive news has been well-received by the market, as reflected in the stock's appreciation since August.

While positive, this is not a "Game Changer" yet. The nickel grades, while consistent, are modest and typical of large, disseminated ultramafic systems. The ultimate economic viability will depend critically on metallurgy—specifically, the ratio of easily recoverable sulphide nickel to more challenging silicate nickel—and the prices of all contained metals. However, for an early-stage exploration project, these results are excellent as they demonstrate size, scale, and consistency, which is exactly what a major partner like Sumitomo wants to see.

Inomin Mines Inc. is a junior exploration company focused on its flagship Beaver-Lynx critical minerals project in south-central British Columbia, Canada. The project covers over 28,000 hectares, is 100% owned by Inomin, and is royalty-free. It is located in an established mining district with excellent infrastructure, adjacent to Taseko's large Gibraltar copper mine. The exploration target is a large, bulk-tonnage deposit of nickel, cobalt, chromium, and magnesium. The company has also sold its non-core Mexican gold-silver assets (La Gitana and Pena Blanca) to focus on Beaver-Lynx.
