SEAGULL PROJECT EXPLORATION

Anteros is in the process of vesting a 20% Phase 1 interest in the Seagull Project (the "Project"), which is currently being explored for hydrogen and helium, as well as platinum, palladium, copper and nickel potential. The Company recently reported base metal and platinum group element assay results from drill hole RM26-01 at the Project, located approximately 80 km northeast of Thunder Bay, Ontario. The Project is operated by Rift Minerals Inc. under the option and joint venture agreement announced October 9, 2025, pursuant to which Anteros may earn up to a 49% interest.

Preparations are underway to resume drilling by late April to early May 2026, subject to field conditions. This next phase will leverage historical drill holes to further evaluate hydrogen and helium potential of gas-bearing structures as reported previously.

STATEMENTS FROM THE BOARD

"We welcome Mr. Drost as Executive Chairman of Anteros," said Bill Kennedy, Director and Founder. "Abraham is a seasoned explorationist who has overseen multiple merger-driven liquidity events. His experience and financial network will be a strong asset to shareholders. The observation of gas indications in three holes, including historical sustained flow in WM01-08, provides compelling evidence of an active gas system on the Project. Combined with our upcoming drill program, we believe we are entering a highly active phase of exploration with the potential to unlock significant value across both the gas and PGE targets."

Incoming Executive Chairman Abraham Drost stated: "In addition to Seagull, the Havens Steady and Strickland Projects in Newfoundland are compelling exploration opportunities."

In addition, the Company announces that Emily Halle will step down from her role as Director and transition into a Strategic Advisor position, where she will continue to support Anteros with her geological expertise and ongoing contributions to the Company's exploration strategy. Anteros thanks Ms. Halle for her service as Director and welcomes her continued involvement as Strategic Advisor.
