Mexico - Laguna

All of Minco's Mexican interests are held indirectly through its investment (26%) in Xtierra Inc., a company whose shares are listed on the TSX Venture Exchange.

Including the Bilbao project, Xtierra holds a total of approximately 12,000 hectares of mining licences in the Panfilo Natera district of Zacatecas state, including a gold project at El Dorado in the historic Pinos gold-silver district.   The area, which forms part of the 500 kilometre long north west trending “Faja de Plata” or Silver Belt, has a prolific mining history dating from before the Spanish colonial period to the present day.

Priority targets include the San Francisco silver-gold epithermal vein systems and potential VMS massive sulphide targets, the Piero y Gia silver lead zinc vein system, the Margarita Dos precious metal vein and the Rancho Nueva silver copper vein.

Orca Minerals’ exploration methodology includes geological mapping, geochemical and geophysical prospecting with reconnaissance drilling of the most promising targets.

The Mexican Silver Belt hosts the majority of the major producing silver mines of the world’s second largest silver producer.  As well as the geologically favourable setting, Minco’s, licences host a number of known small mineral occurrences and nearby there are several discoveries by other explorers.

Xtierra's exploration in Mexico is directed at three main types of deposits:

  1. Silver/Zinc/Lead skarns
  2. Silver/Gold veins with associated base metals
  3. Zinc/Copper/Gold volcanogenic massive sulphides
