Volcanic Gold Mines secures Guatemalan antimony mine right of refusal

August 24, 2026 – TheNewswire - Vancouver, British Columbia – Volcanic Gold Mines Inc. (TSXV: VG) (“ Volcanic ” or the “ Company ”) is pleased to announce it has secured a Right of First Offer and Right of First Refusal to acquire an interest in the fully permitted Los Angeles antimony mine in Palencia, Guatemala, from private operator, Compania Minerales de Guatemala, S.A. (“ MINEGUA ”).

Volcanic is providing geological and sampling support to MINEGUA for a 1,000 m exploratory drill program aimed at expanding the existing small-scale open-pit operation.

Strong, independently verified sampling results

Volcanic’s geologists carried out a systematic channel sampling program of the flat-lying to gently dipping antimony horizon exposed along the 200 m long open-pit face. Sixty-one saw-channel samples were collected from thirteen vertical channels at 10–15 metres spacing along the open pit face. Each channel ranged from 1.5 to 3 m in length, with individual samples cut at a consistent 0.5 m interval to ensure accuracy and representativeness.

The results confirm genuine, high-grade antimony mineralization:

Oxide zone (Planchon): 6 channels averaged 1.6 m at 6.1% Sb and 17.5 g/t Ag

Sulphide zone (Manzanal): 7 channels averaged 1.6 m at 4.1% Sb and 16.8 g/t Ag

Overall weighted average along entire 200 m face: 1.6 m at 5.0% Sb and 17.1 g/t Ag

Individual channels returned grades as high as 17.8% Sb with 68.7 g/t Ag and 10.8% Sb with 85.2 g/t Ag.

Drilling progress

Eleven diamond drill holes totalling 1,041 m have been completed. Five holes successfully intercepted antimony mineralization, including a new deeper zone extending 300 m along strike of the current pit that remains open in multiple directions. Assay results are pending.

The Property

The Los Angeles property covers a 12 km² exploitation licence (plus a pending 9.5 km² extension) located approximately 40 km east of Guatemala City. Current open-pit mining has reached its practical limit with existing equipment, creating a clear opportunity for expansion through additional investment in exploration, mining, and processing.

Volcanic looks forward to receiving the pending drill assay results and evaluating the potential to significantly grow this high-grade antimony project.
