This project is located in northeastern Sonora State, Mexico; about 20 km east of the La Caridad open pit copper mine. Valenzuela (also referred to as "El Valle") is within in the western foothills portion of the Sierra Madre epithermal trend. About 40-50,000 tonnes of material have been underground mined from 2 epithermal quartz veins hosted in Cretaceous-Tertiary aged volcanic rocks at Valenzuela. Underground sampling of one vein has returned up to 1,500 g/t silver & 5 g/t gold, and limited sampling of leached vein material at surface elsewhere in the project has returned up to 600 g/t silver. More than 8 veins and limited stockwork can be traced across the ridge hosting the mineralized system.
Pediment's latest sample survey consisted of collecting 41 underground samples of vein material and altered wall rock and 153 surface rock chip samples of 1-2 meters length across weathered vein exposures. The survey also determined that northeasterly to easterly trending veins contain areas of significant or anomalous silver and/or gold, while one north trending vein contains low metal values.
Significant results include:
a. The San Patricio Vein, the most northerly of the exposed veins, returned an average 928 g/t silver and 1.6 g/t gold in four samples taken along 100 meters of strike, including a single sample that returned 2,890 g/t silver and 5.6 g/t gold. The northernmost San Patricio sample returned 406 ppm silver and 0.45 g/t gold.
b. The Amanda Vein averaged 347 g/t silver and 0.84 g/t from three samples taken along a 75 meter strike, plus anomalous gold (0.08 to 0.14 g/t) with up to 187 g/t silver from six other samples along a further 275 meters.
c. The Amelia Vein returned anomalous gold (0.1 to 0.31 g/t) results along 200 meters, and La Valenzuela Vein and splay veins that have most of the old workings returned similar results along about 400 meters of trend.
As a result of this work Pediment has purchased two internal claims from a third party, and now holds a contiguous block of 400 hectares containing La Valenzuela system with no underlying interests or royalties. Further detailed mapping plus grid based geochemical and geophysical surveys plus road building will complete drill targeting for high-grade material, as well as for bulk tonnage material if results warrant.
