Outstanding Apollo Silver Warrants Expire in July 2026

Apollo Silver Corp. (TSX-V:APGO) (OTCQB:APGOF) (Frankfurt:6ZF) is pleased to announce that, through its wholly owned subsidiary, Stronghold Silver USA Corp., the Company has completed all payments required under the Option to Purchase Agreement dated December 21, 2020, as amended January 21, 2023, with Athena Minerals Inc. As a result, the Company now owns 100% interest in thirty-six unpatented lode mining claims comprising part of the Langtry Property, which forms part of the Calico Silver Project, in San Bernardino County, California.

Under the terms of the Athena Agreement, the Company had the right to acquire the Athena Claims for an aggregate purchase price of US$1,000,000, payable on or before December 21, 2025. An initial payment of US$15,000 was paid upon execution of the Athena Agreement in December 2020, followed by annual payments of US$25,000 on each anniversary date. Between 2021 and 2024, the Company made the required annual payments. In accordance with the Athena Agreement, payments made within the twenty-four months preceding option exercise were credited against the purchase price, resulting in a final cash payment of US$950,000 to vest 100% ownership of the Athena Claims.

Pursuant to the Athena Agreement, the Company has granted Athena a 1% net smelter return royalty on future mineral production from the Athena Claims. The NSR applies only to those claims that do not already carry an existing royalty of 1% or greater, and in all cases the total royalty burden on any claim will not exceed 2%. The acquisition of the Athena Claims consolidates Apollo Silver’s land position at the Calico Silver Project and represents a significant milestone in advancing the Company’s silver and critical minerals strategy in the region (see Figure 1).
