Projects

The wholly owned Puebla de la Reina (PBR) property covers 8,924.24 hectares located in Extremadura, Spain.  The PBR property hosts two areas of mineralization 1) Las Poyatas in the west, and 2) Las Herrerias in the east.

The main focus historically, and that of Merida, has been the Las Herrerias Zn-Cu-Pb-Ag prospect.

The Puebla de la Reina asset is located in an established and stable mining jurisdiction:

  • 5 km from the nearest cities
  • 20 km from mining ministry office
  • 80 km from the nearest concentrator
  • 100 km from Seville

Infrastructure, such as road, power and water access built out.

 

Outukumpu (1999-2001)

Outukumpu indicated a provisional estimated resources at the Puebla la Reina deposit,

500,000t @ 1.6% Cu, 11% Zn, 1.2% Pb and 32 g/t Ag

At present the structure was only recognized on the northeastern area of PBR. Further works to consider the extension of exploration toward the west and southwest area of volcano-sedimentary formation

Geology and Mineralization

The PBR deposit represents a typical Cu-Zn-Pb volcanic- hosted massive sulphide orebody.  It was discovered by the IGME (the National Institute of Mining and Geology in Spain) in 1981 and consists of several stratiform lenses up to 9 m thick and 150 m long set in syn-Cadomian felsic volcaniclastic sandstones and massive dacites, with minor massive andesites, shales and limestones

The footwall and hanging wall of the deposit show a pervasive hydrothermal alteration which is strongly dependent on the type of protolith. Felsic volcanic rocks are chloritized and sericitized and strongly silicified adjacent to the orebody

Disseminated sulphides are common in the altered zones. The mineralization consists of pyrite, chalcopyrite, sphalerite and galena, with trace amounts of tetrahedrite and arsenopyrite, besides minor carbonates, quartz and illite

These deposits probably formed in an arc or back-arc setting and share many features with those of Kuroko-type, i.e., the bimodal-felsic type of deposits
