Aquincuari
Ten mines and prospects within a 2 × 2.5 km camp, all fault-controlled within large silicified envelopes. Its two principal mines reportedly graded 6.8 and 16.0 g/t Au over 1.4–2.0 m widths, worked to depths beyond 100 m.

The San Blas Mining District: epithermal gold in Mexico’s Sierra Madre

- San Blas Mining District
One of the world’s great precious-metal belts
The Sierra Madre Occidental is a 200–300 km wide Tertiary volcanic province running 1,300 km southeast from the U.S. border — among the largest epithermal precious-metal provinces on Earth and host to most of Mexico’s gold and silver deposits. Its low-sulphidation systems include some of the deposit class’s global benchmarks; within the province, the San Dimas camp alone has reported production and resources on the order of 9 million ounces of gold and hundreds of millions of ounces of silver. Mining here dates to the Spanish colonial era, and Sinaloa’s districts — San Blas among them, active since at least the 1880s — carry that lineage.
District architecture
Calderas and NE-trending structures
The San Blas district, in Sinaloa’s far north near El Fuerte, is characterized by volcanic-hosted, hot-spring-type, low-sulphidation epithermal Au–Ag deposits — veins, breccias and occasional replacements, much of it bonanza-style, with quartz–sericite–carbonate–chlorite alteration. Regional mapping outlines a crudely circular, ~12-km ring of andesite-porphyry intrusive centers — a postulated caldera — cut by a swarm of NE-trending dilatant normal faults. Every significant deposit and silicified zone mapped in the area sits on one of those NE structures.
Jecacahui
A 1-km NNE-trending fault system with three prospects including a past producer, in quartz veins carrying gold, silver and copper.
Under-explored, by modern standards
Neither camp has seen modern systematic exploration — true of much of the district, which is precisely what makes it interesting. Sinaloa has drawn renewed institutional exploration investment over the past decade as the industry re-rates Mexico’s epithermal belts.
Where Charay sits
The center of the system
The Charay Project (Mina El Padre) occupies the center of the postulated caldera, on a NE-trending structure of its own — the El Padre vein — with the geology, textures and metal zonation of the district’s deposit class fully expressed: colloform banded chalcedonic quartz, a silica cap, oxide-to-sulphide transition near 50 m, and grades that strengthen downward. Nineteen core holes averaged 20.3 g/t Au and 123.7 g/t Ag over 1.29 m true width in the top 50 m, with the system open in every direction and an adjacent 500 × 200 m silicified breccia untested at depth.
