First Majestic Silver has completed approximately 89,000 m of a planned approximately 117,000 m 2026 drilling program at San Dimas, where high-grade silver and gold intercepts expanded exploration targets. The results matter because they support near-mine Mineral Resource conversion, future resource growth, follow-up drilling and a potential near-term Mining opportunity.

Key Highlights

  • The September 9, 2026 update covers drilling across the San Dimas district in Durango, Mexico.
  • Convención and El Cristo results expanded the exploration footprint and created targets for additional follow-up drilling.
  • Drilling in the Coronado and Carmen Escobosa vein system supports a two-vein mineralized system and potential Mineral Resource addition in the West Block.
  • Initial drilling at the Convención vein produced significant intercepts in five of seven holes, with the structure remaining open in multiple directions.

San Dimas Drilling Advances

Work at Convención and El Cristo has also expanded the exploration footprint. Results from the Sinaloa-Elia vein complex support the continuity and potential growth of the mineralized system. Drilling in the Coronado and Carmen Escobosa vein system has continued to support the interpretation of a two-vein mineralized system. The work is focused on potential Mineral Resource addition in the West Block.

New Targets Extend Footprint

At Convención, geological analysis around the Jessica vein identified a structure interpreted as the Convención vein. Initial drilling produced significant intercepts in five of seven holes, supporting the exploration hypothesis. The Convención structure remains open in multiple directions. Exploration has also expanded into the El Cristo mine area, including the Luz and Patricia veins.

Resource Growth Remains Focus

Results received to date support potential Mineral Resource growth within established vein systems. FIRST MAJESTIC SILVER CORP (NYSE: AG) said the new Convención and El Cristo opportunities will receive follow-up drilling. The exploration work is also intended to test new targets and identify additional growth opportunities throughout the district.
