La Luz Silver Project
Overlooking Real de Catorce
The La Luz Silver Project is located in the northern portion of San Luís Potosí State, Mexico. The property is approximately 25 km west of the town of Matehuala and 170 km due north of the city of San Luís Potosí, the state capital.
The ore deposits in the district are epithermal veins system-low sulfidation type which are hosted in sedimentary rocks ranging in ages from Paleozoic (metamorphosed sediments), Triassic (Huizachal Formation), Jurassic (Zuloaga and La Caja limestones) to mid-Tertiary (Quartz-monzonite dikes and Basalts). The main veins are: San Agustin (N50°W, 2,300 metres long, 2 to 10 metres wide), Veta Madre (N62°W, 2,500 metres long, 1 to 10 metres wide), Ave Maria (N70°E, 550 metres long, 0.5 to 6 metres wide) Villanos-San Ramón (N40°W, 1,200 metres long, 0.1 to 5 metres wide) and San Agustín system (N48°W, 2,200 metres long, 0.2 to 10 metres wide). There are also several blind (not outcropping) veins that were intersected by drill holes. Economic mineralization is in almost vertical ore-shoots with vertical extensions of 200 to 400 metres. The presence of the most important ore shoots are related with favorable rocks like La Caja and Zuloaga limestones and in the inflections and intersection of structures.
