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.

Kingsmen Resources reported 218 g/t silver equivalent over 6.45 metres at its Las Coloradas project in Chihuahua, including 338 g/t over 1.95 metres. The hole intersected the newly identified #8 structure, 150 metres west of an earlier high-grade drill hole, adding evidence of mineralization across multiple structures.

Minaurum has rehabilitated more than 600 metres of the historic Promontorio mine’s main haulage level and gained access to its 55-metre-deep Balvanera shaft at the Alamos project in Sonora. Preliminary underground channel samples include 0.30 metres grading 4,142 g/t silver equivalent. The access enables further mapping and sampling of the vein system.

Kootenay Silver reports new Lupe Vein intercepts at its Columba project in Chihuahua, including 94 g/t silver over 84.45 metres and 209 g/t over 8.3 metres. Lupe has been traced for roughly 520 metres along strike and 450 metres vertically and remains open. More than 30,000 metres of the planned 60,000-metre program are complete.

Chesapeake Gold reports that tests of its heap oxidation process at Metates, Durango, achieved 70% gold and 61% silver recovery from the main intrusive domain in 90 days, versus 240 days in earlier testing. It is evaluating further improvements for a planned prefeasibility study and testing the process on six third-party projects.

Mammoth Resources has collected a 200 kg metallurgical sample from the Carneritos area of its Tenoriba gold-silver project in Chihuahua. The sample will undergo vat and column leach testing at the Universidad de Sonora to assess recovery options for potential small-scale production. The company also reviewed drill core, site access and plans to renew surface access agreements.

GoGold reports that construction at Los Ricos South in Jalisco remains on schedule for first silver production in the second quarter of 2028. More than 150 contractors are on site, plant design is 90% complete, and all long lead equipment has been ordered. The company says the project is fully funded.

Advance Metals reports further silver and base metal mineralization at its Gavilanes project in Durango. Hole GV-26-008 returned 4.6 metres grading 945 g/t silver, including 1 metre at 4,120 g/t silver. A deeper interval yielded 12 metres grading 3.8% zinc and 3.7% lead, extending the mineralized system below earlier drilling.

Antimony Resources commenced ASX trading under ticker ANT following its name change from EV Resources. At the Tecomatlán antimony processing plant in Mexico, crushing for the proof-of-concept campaign is underway, with material being stockpiled ahead of grinding and flotation as the company advances toward full commissioning.
