Vancouver, British Columbia--(Newsfile Corp. - September 22, 2026) - Inomin Mines Inc. (TSXV: MINE) ("Inomin" or the "Company") has staked a new mineral claim, covering approximately 1,128-hectares, adjacent to the Beaver-Lynx polymetallic project. The claim covers most of a 5-kilometre-long magnetic feature identified by airborne magnetic surveying. As mineralization at Beaver-Lynx is typically associated with magnetite, this ground likely represents another large, high-priority target for nickel and other critical minerals.

Upon receipt of government approval, the mineral claim will become subject to the Earn-in and Joint Venture Agreement dated April 25, 2025 between Sumitomo Metal Mining Canada Ltd. ("Sumitomo") and the Company. The Beaver-Lynx Management Committee will determine whether to include it in the project. Should the claim not be included in the Beaver-Lynx project, Inomin will own the property exclusively.

Inomin has applied for a new mineral claim outlined in blue covering a substantial target.

John Gomez, President & CEO of Inomin, commented, "The new claim represents a highly efficient expansion of Beaver-Lynx. By staking this magnetic anomaly, we position Inomin to leverage the same geological hallmarks driving our exploration successes. Upon anticipated approval, this claim integrates into our earn-in structure with Sumitomo, or remains the sole ownership of Inomin, monetizing additional value for our shareholders."

About Beaver-Lynx

The 28,000-hectare Beaver-Lynx project is located approximately 50 kilometres north of Williams Lake and adjacent to Trekor Metals Ltd.'s Gibraltar mine, Canada's second largest open-pit copper operation. The project benefits from excellent infrastructure, including all-season road access, nearby hydroelectric power, and proximity to an active rail haulage line. Local communities provide comprehensive services and a skilled workforce.

Until 2026, exploration focused exclusively on the Beaver block, where drilling has outlined extensive nickel and magnesium mineralization, along with cobalt, chromium, platinum, and palladium. Drilling has also intersected copper, silver, and gold, underscoring the polymetallic nature of the system.

The Lynx block, located 10 kilometres south of Beaver, hosts multiple high priority magnetic and geochemical targets comparable in size - and in some cases larger - than those at Beaver. Together, Beaver and Lynx outline a significant district scale critical minerals opportunity.

The 2026 Beaver-Lynx exploration program is being undertaken in collaboration with Sumitomo that are funding the program; Inomin is the project operator. For further information, visit www.inominmines.com.
