Areas feature silicified breccia and quartz veining; assays pending. Expands 3.2km corridor; trenching and drilling to follow.

Sierra Madre Gold and Silver restarts exploration at East District of Guitarra project, Mexico, with US$3.5M budget for mapping, sampling, and 20-25k meter drilling to assess historic veins’ potential. Includes Mina de Agua resources. Marketing agreements signed; CFO Ken Scott appointed Corporate Secretary Nov 1.

DynaResource (OTCQX: DYNR) installs three Falcon gravity concentrators at San Jose de Gracia plant in Mexico, creating primary gravity gold circuit to boost recoveries from 75% to >80%. Units commissioned; ramp-up to design capacity by Oct end, with Sepro assistance for optimization.

Silver Storm Mining has commenced rehabilitation at its La Parrilla Silver Mine in Mexico. Dynamic Engineering is leading plant rehab, expanding the sulphide circuit 25% to 1,250 tpd (7-9 months). Long-lead items ordered; underground works (drift cleaning, ventilation) underway. SRK reviews restart plan, targeting potential Q2 2026 production.

Tocvan Ventures mobilized equipment to North and South Blocks of Gran Pilar Gold-Silver Project on Oct 20, 2025, advancing road access, site clearing, trenching, drilling (first rig to North Alteration Zone), and pilot mine preparation; targeting new zones with upcoming milestones including 2,000-8,000m drilling.

“Today’s results show that the La Colorada mine can continue to be a high-margin, low CAPEX operation with a 6.1-year mine life. This updated study is focused on the open pits at La Colorada, demonstrating positive economics at conservative gold prices and a compelling opportunity at current gold prices. The Company aims to continue to maximize cash generation from stockpiles in the near term and internally fund capital requirements for open-pit production planned in 2027.”
