Global Tactical Metals Corp. Reports Overlimit Results in Second Round of Sampling at Green Mine, Nevada

Toronto, Ontario--(Newsfile Corp. - May 6, 2025) - Global Tactical Metals Corp. (CSE: MONI) (FSE: A7F) ("Global Tactical Metals" or the "Company") is pleased to announce encouraging results from its second round of sampling at the past-producing Green Mine in Nevada. Of the 10 samples collected, 7 returned over-limit values for antimony (Sb), reaffirming the high-grade nature of this critical mineral occurrence. Select samples also returned over-limit values for silver (Ag) and lead (Pb). At the Green Mine, mineralized veins host jamesonite (Pb₄FeSb₆S₁₄), secondary bindheimite (Pb₂Sb₂O₆(O,OH), pyrite, arsenopyrite, and possibly boulangerite (Pb₅Sb₄S₁₁).

This second round of sampling confirms the presence of polymetallic mineralization both at surface and within historic underground workings, supporting the Company's view that Green Mine holds strong potential for further development.

Sampling

Samples were collected from surface dumps adjacent to historic mine workings, exposed outcrops, and within the underground adits. Notably, 70% of the samples exceeded the upper detection limit of 10,000 ppm for antimony. Additional elevated results were recorded for silver and lead.
