Testing of 18 selected Cerro Grande core samples found mineralized skarn denser and more chargeable than the tested host rocks. Algo Grande plans a 1,296-station gravity survey at Adelita to refine exploration targets. Drill hole AG-CG-PH2-003 intersected skarn with visible copper sulfides; assays are pending.

Sonoro Gold reported results from 26 additional holes at Cerro Caliche, Sonora, expanding mineralization at Diana and outlining the La Colorada zone. Highlights include 28.95 metres grading 2.598 g/t gold and 47.24 metres at 1.552 g/t gold. The ongoing 50,000-metre campaign has completed 14,086 metres in 72 holes. True widths are estimated at 60–90% of drilled lengths. globenewswire.com

Masivo Silver’s first 2026 hole at Cerro Colorado, Sonora, intersected 32.5 metres grading 0.271% zinc, 7.0 g/t silver and 0.141% lead, plus copper and gold. Drilling stopped at 259.5 metres due to technical difficulties while still in mineralized rhyolitic porphyry. Grades strengthened near the bottom, supporting follow-up drilling. True widths remain unknown.

Centenario Gold has begun a maiden 1,500-metre drill program at Los Reyes, Chihuahua, comprising five to six holes, 200–500 metres deep. Drilling targets depth extensions of skarn mineralization beneath the historic Jibosa and Tueda workings. Previous underground sampling returned up to 27.9% copper at Jibosa and 2.1% molybdenum at Tueda.

Phase 1 modifications lifted Guitarra plant throughput to 720 tonnes per day, over 40% above its previous 500-tpd capacity. Sierra Madre reported the new ball mill installed and expected commissioning in November, supporting a Phase 2 target of 1,200–1,500 tpd. Mine development reached 2.6 km since June, and groundwork began for the tailings facility expansion.

Torex reported strong drilling across its Morelos property in Guerrero. Highlights include 31.2 m at 11.28 g/t gold equivalent in the emerging San Miguel corridor and 35.0 m at 14.32 g/t at ELG Underground. Torex added 13,400 m of Media Luna Cluster drilling, raising its 2026 Morelos exploration budget to US$51 million.

Torex reported high-grade results from 15-rig drilling across Morelos, including 11.28 g/t AuEq over 31.2 m along the emerging San Miguel corridor and 56.8 g/t AuEq over 6.4 m at ELG Underground. The company raised its 2026 exploration budget to US$51 million; a reserve and resource update is expected in March 2027.

Minaurum reported step-out results from its Alamos Silver Project in Sonora, including 3.40 m at 397 g/t silver equivalent at Europa Sur, 1.90 m at 323 g/t at Quintera, and 0.90 m at 1,469 g/t at San Jose. The results support its ongoing 50,000 m resource expansion program; Quintera and Europa Sur were excluded from the initial resource estimate.

Algo Grande’s hole AG-CG-PH2-002 at Adelita in Sonora intersected two separate copper-silver-gold skarn zones totaling 68.43 metres at an average 1.2% CuEq. The newly reported lower zone returned 38.20 metres at 1.0% CuEq, about 67 metres below the previously reported upper zone. Intervals are downhole lengths; true widths and metallurgical recoveries remain undetermined.

At its Gran Pilar project in Sonora, Tocvan drilled 106.8 m grading 0.50 g/t gold and 3.5 g/t silver within a broader 271.5 m interval. The hole extends El Mezquite mineralization 130 m north of the discovery hole. The trend is now traced for about 1.4 km and remains open.
