Vancouver, British Columbia--(Newsfile Corp. - May 12, 2026) - Inomin Mines Inc. (TSXV: MINE) ("Inomin" or the "Company") and Sumitomo Metal Mining Canada Ltd. ("Sumitomo") have commenced the 2026 exploration program at the 28,000-hectare Beaver-Lynx polymetallic project in south-central British Columbia. The approximately $2.3 million program represents the largest single exploration investment at Beaver-Lynx to date and includes first-ever drilling at the Lynx block.

The program will focus on approximately 4,100 metres of drilling at the Onuki zone, a 6 km² target within the Lynx area. Previous outcrop sampling at Onuki returned values up to 2,640 ppm nickel. Onuki is one of several 3-6 km² magnetic targets identified through airborne surveys and surface rock sampling at Lynx. Mineralization at Lynx exhibits characteristics similar to the Beaver block to the north, where Inomin has delineated multiple zones of near-surface nickel-magnesium-cobalt mineralization and, more recently, platinum and palladium at the Beaver South zone.

John Gomez, President of Inomin, comments, "Initiating the first drilling at Lynx is an important milestone. The targets at Lynx are generally larger and more numerous than those we have tested at Beaver. Success at Onuki would support the presence of a district-scale mineral system across Beaver-Lynx."

A detailed ground magnetic survey is currently underway at Onuki to refine drill targeting. Subject to permitting process of the Beaver block, some drillholes at Onuki zone will be reallocated to the Beaver South zone to continue expanding the mineralized footprint and advance the project.

About Beaver-Lynx

The 28,000-hectare Beaver-Lynx project is located in south-central British Columbia, approximately 50 kilometres north of Williams Lake and adjacent to the Gibraltar mine, Canada's second-largest open-pit copper operation. The project benefits from exceptional infrastructure, including all-season road access, nearby hydro-electric power, and proximity to active rail lines. The surrounding resource communities provide comprehensive services and a skilled workforce.

Exploration to date has focused exclusively on the Beaver block – including multiple drilling campaigns – indicating the property may host large volumes of nickel and magnesium, along with cobalt, platinum, and palladium. Drilling has also intersected chromium, copper, silver, and gold, underscoring the polymetallic nature of the system.

The adjoining Lynx block, located 10 kilometres south of Beaver, hosts multiple high-priority magnetic and geochemical targets comparable in size – and in some cases potentially larger – than those at Beaver. Together, the two blocks outline a significant district-scale critical minerals opportunity. For further information, please visit www.inominmines.com.

Airborne Magnetics and Rock Sampling at Lynx Block

An airborne magnetics survey completed over Lynx delineated 8-kilometre-wide ring-like magnetic anomaly and several strong magnetic anomalies – all greater than 2 kilometres in length – denoted as the Bear, Skulow, and Onuki areas. These three areas were the focus of prospecting; of the 17 rock samples chipped from outcroppings, 9 contained greater than 0.1% nickel with the highest grading sample containing 0.27% nickel.
