First Majestic Silver Corp. has returned multiple high-grade silver and gold intercepts from its ongoing 2026 exploration program at the San Dimas underground mine in Durango, Mexico, highlighted by drill hole LUZ26X-02 intersecting 1.30 metres grading 2,625 grams per tonne silver and 58.25 grams per tonne gold, or 6,994 grams per tonne silver equivalent, at the Luz vein.

The ongoing 2026 campaign at San Dimas incorporates approximately 117,000 metres of planned drilling. First Majestic has completed approximately 89,000 metres year-to-date, with activities focused on resource-conversion and resource-addition drilling across the West Block, Central Block, and Graben block, alongside target testing in the East and Arana blocks.

Recent drilling within the El Cristo mine area also intersected high-grade mineralization at the Patricia vein, where drill hole LUZ26X-03 returned 1.69 metres grading 1,895 grams per tonne silver and 28.91 grams per tonne gold, representing 4,063 grams per tonne silver equivalent.

In addition to near-mine testing, exploration around the Jessica vein identified a hanging wall structure termed the Convención vein approximately 100 metres to the north. Initial drill testing returned five significant intercepts in seven holes, including an interval of 2.57 metres grading 251 grams per tonne silver and 2.56 grams per tonne gold in hole SJE26X-08.

“San Dimas continues to validate its position as one of our most prospective and enduring mining districts,” stated Keith Neumeyer, CEO of First Majestic. “The latest drill results have returned multiple high-grade silver and gold intercepts from both resource-conversion and resource-addition programs, reinforcing the near-mine growth potential of established vein systems while expanding the exploration footprint at Convención and El Cristo. With approximately 117,000 metres of drilling planned in 2026, we are advancing one of the Company's largest exploration programs, focused on Mineral Resource conversion, testing new targets and identifying additional growth opportunities throughout the San Dimas district.”

First Majestic expects to complete the remaining portion of the 117,000-metre drilling program over the remainder of the year to support continued Mineral Resource conversion and expansion across the district.
