Diamond drill results from the Erika gold prospect in southern Mexico indicate the upper levels of a preserved, low-sulphidation epithermal system.
Almaden Resources (AMH-V) recently drilled eight holes on the property, situated in Guerrero state, in a program aimed at testing several geological, geochemical and geophysical targets.
The deposit contains fragments of vein material, silicified sediments and volcanics, with late-stage silicification and pyrite in a clay-Altered matrix. Some fragments are partially replaced by pyrite.
Assays are pending, though Almaden reports that holes 4, 5 and 8 intersected broad zones of favorable alteration mineralogy.
Meanwhile, work is continuing at the company’s 40,000-Acre Caballo Blanco gold-silver-Copper property, 400 km east of Mexico City.
Geologic mapping is nearly complete for the south-Central portion, and final plots from a geochemical soil sampling program have been received.
Almaden has outlined several coincident gold-Copper anomalies associated with what appear to be two styles of mineralization within a large alteration zone.
In one area, two creeks contain float rock of porphyry-style quartz stockwork veining associated with copper-gold mineralization and K-silicate alteration.
A grab sample of float rock from that area assayed 1.68 grams per tonne, 24.6 grams silver and 13% copper.
