Anteros Metals Reports Drilling Update at Seagull Critical Minerals Project, Ontario

Anteros Metals Reports Drilling Update at Seagull Critical Minerals Project, Ontario

Anteros Metals Inc. (CSE: ANT) ("Anteros" or the "Company") provides the following update for the Seagull Critical Minerals Project (the "Project"), located approximately 80 kilometres northeast of Thunder Bay, Ontario. Drilling is being carried out by Rift Minerals Inc. ("Rift"), as operator, pursuant to the option agreement announced on October 9, 2025, under which Anteros may earn up to a 49% interest in the Project. The Project is being evaluated for platinum group elements, base metals, and naturally occurring gases, including hydrogen and helium.

Further to the Company's news release dated January 21, 2026, Anteros reports that during drilling at the Project, gas was encountered at a depth of approximately 877 metres in the early morning hours of January 23, 2026. Drilling has been temporarily suspended and the hole secured while the Company and the project operator evaluate downhole conditions and determine appropriate next steps for continued safe drilling and gas sampling.

The nature, composition, volume, and significance of the gas are currently unknown. Specialized sampling equipment has been mobilized to site to support further evaluation. The originally planned target depth of the drill hole is approximately 1,350 metres. The Company will provide further updates as information becomes available.

ABOUT THE SEAGULL PROJECT

The Project is located approximately 80 kilometres northeast of Thunder Bay, Ontario, and covers the interpreted mafic-ultramafic Seagull Intrusion within the Nipigon Basin. Historical exploration between 1998 and 2012 included airborne geophysical surveys and approximately 20,000 metres of diamond drilling, which reported disseminated to semi-massive sulphide mineralization containing nickel, copper, and platinum-group elements along parts of the intrusion's basal contact. These results are historical in nature and have not been independently verified by Anteros.

In 2024, Rift completed an Ambient Noise Tomography ("ANT") survey to refine the internal geometry of the Seagull Intrusion and to help define a deeper subsurface target. The survey outlined contrasting velocity domains interpreted to reflect lithological and alteration variations. These interpretations remain unverified by Anteros, and the ongoing Phase 1 drill program is intended to provide the first subsurface evaluation of the deeper ANT anomaly.
