The Aurifero gold project contains a swarm of gold- and silver-bearing epithermal veins within a NW/SE-trending zone measuring 3 km long and more than 400 m wide.
A NW-SE trend of structurally controlled ridges and valleys extending from northwest of Aurifero project to the east-southeast of the Piedras Verdes porphyry copper deposit. Gold mineralization in the Aurífero project area is associated with NW-SE fracture zones, veins, and rhyolite dikes, cutting intermediate to felsic tuffs. Quartz-eye rhyolite dikes and strong argillic alteration in a number of the shallow underground workings suggest that mining has been limited to the uppermost levels of a mineralized epithermal system. Aurifero mineralization appears to be spatially and temporally related to the emplacement of fine-grained felsic intrusions (dikes and small stocks), the nature and extent of which were not clearly identified in historical work.
The project has seen numerous campaigns of shallow reverse circulation and core drilling since the 1980s totaling over 8,000 metres. Holes were on average less than 100 m deep; the deepest reaching a vertical depth of 135 m from surface.
The project is 35 km northwest of the Alamos silver project, and 15 km northwest of Cobre Del Mayo's Piedras Verdes copper mine. The total size of the project is 1,229 hectares.
Project terms include completing cash payments of CDN $2,686,000 over 96 months.
The project has seen numerous campaigns of shallow reverse circulation and core drilling since the 1980s totaling over 8,000 metres. Holes were on average less than 100 m deep; the deepest reaching a vertical depth of 135 m from surface. Please see Minaurum news release dated January 29, 2020. Stephen R. Maynard, Vice President of Exploration of Minaurum and a Qualified Person as defined by National Instrument 43-101, acuracy of the historical drilling data reported has not been verified.
Drill program to test at depth targets has been designed and drill permits have been submitted. Work continues to consolidate the district.
Historical drilling highlights, Aurífero project. Minera Terrazas and Pershimco performed diamond (core) drilling; Peñoles used a reverse-circulation drill.
