The San Celso project contains five high grade veins within a low-sulphidation epithermal system. Grades of up to 395g/t Ag, 13,700ppm Pb, and 13,900ppm Zn have been assayed.
The two principal veins being the San Celso and Las Cristinitas veins, which have thicknesses ranging between 1 and 5 metres.
Project scale mapping and sampling has discovered several unexploited veins that returned grades in excess of 100g/t Ag with minor gold and base metal credits that suggest additional silver-bearing structures exist.
None of the veins appear to have been systematically drilled previously, to define a compliant resource.
Historic colonial-era mines extend to the depth of the water table, approximately 90-100 metres but the Company believes there to be considerable depth potential to both the San Celso and Las Cristinitas veins.
Each of the accessible mines has numerous stopes indicating the presence of high grade shoots within the San Celso and Las Cristinitas veins.
Alien Metals' initial observations of the vein systems indicate similarities to the Company’s previously owned and nearby San José mine, where historic mining exploited the San José vein down to approximately 300 metres and a NI-43-101 compliant mineral resource estimate of approximately 117 million ounces indicated/inferred contained silver*.
