Executive Summary

First Majestic Silver Corp. announced significant drill intercepts from its 2024/2025 exploration program at the Los Gatos Silver Mine, highlighting high‑grade silver‑equivalent (AgEq) intervals across South‑East Deeps, Central Deeps and North‑West Deeps zones.
Several intercepts exceed 500 g/t AgEq (marked “Include”), with the highest reported grade of 1,080 g/t AgEq (GA‑SE‑DV‑612 Include 1).
The results support the company’s expectation of meaningful mineral resource growth at Los Gatos and indicate that the orebody remains open along strike to the northwest.
