Anteros Metals Commences Drilling at Seagull Critical Minerals Project, Ontario

Executive Summary

• Anteros Metals Inc. announced that drilling has begun on the Seagull Critical Minerals Project in Ontario, targeting a deep, previously untested anomaly identified by Rift Minerals’ Ambient Noise Tomography survey.
• The Phase 1 program consists of an approximately 1,350‑metre diamond drillhole designed to evaluate potential PGE, nickel, copper, hydrogen and helium mineralization; the program is fully funded and permitted.
• Anteros will provide further updates as drilling progresses and results become available.

Key Details

• Drill crews mobilized to site; casing has been cemented and drilling is underway.
• Project location: ~80 km NE of Thunder Bay, Ontario, within the mafic‑ultramafic Seagull Intrusion (Nipigon Basin).
• Phase 1 drill program: ~1,350 m deep diamond drillhole testing a low‑velocity anomaly identified by Rift’s Ambient Noise Tomography (“ANT”) survey.
• Target commodities: platinum‑group elements (PGEs), nickel, copper, and associated naturally occurring gases (hydrogen, helium).
• Gas sampling will be conducted by a specialized team later in the month; sampling is investigatory and does not imply commercial gas resources.
• The drill program is fully funded and fully permitted.
• Historical context: 1998‑2012 exploration included ~20,000 m of diamond drilling with reported disseminated to semi‑massive sulphide mineralization (Ni, Cu, PGEs) – results unverified by Anteros.
• 2024 Rift ANT survey refined internal geometry of the intrusion and identified a deeper subsurface target now being tested.
• Qualified Person: Dr. Geoff Heggie, P.Geo. (Ontario), reviewed and approved technical information under NI 43‑101.
