Villa Union

Villa Union Summary

The Villa Union project comprises 5600 Ha of mining concessions and is located 12km north of the Rosario mine, Minera Penoles S.A de CV is a major Mexican mining company in a significant historical mining district. Villa Union’s attractive location covering 5km of the western edge of the Panuco Graben, and 7km of the western edge of the Rosario Graben, host to the Rosario mine, provides an immediate target for precious metals exploration.


Regional geology

The Villa Union project hosts predominantly hydrothermally altered (prophylitc-argilic) olygocene porphyritic andesites. On the NE boundaries of the Villa Union concessions, near the edge of the Panuco graben, prevalent Tertiary volcanic structure occurrences, commonly andesites, which correlate to the upper volcanic sequence.  These structures typically host gold and silver mineralization in the Sierra Madre Occidental. There are major tectonic structures in the center of the Villa Union concessions, offering further evidence of potential hydrothermal fluid conduits and potential sites for exploration.


Exploration status

GR Silver Mining has recently completed regional reinterpretation studies of data published by the SGM (Geological Survey of Mexico).  Data sets covered by the Company’s reinterpretation study program include aeromagnetic data (complete) and geological maps at a 1:50,000 scale (still underway). Follow up targets have been generated by combining the aforementioned studies with detailed analyses of stream sediment and surface sampling programs completed by previous companies.
