Crosby & Pirquitas NorteLocation:
The Crosby and Pirquitas Norte properties are located in the north-east of the Province of Jujuy within the Departments of Rinconada and Cochinoca. These two properties surround the restarted Pirquitas Ag-Sn-Zn mine property on 3 sides (W, N and E).
Target Type:
In the Crosby and Pirquitas properties the target mainly comprises extensions to the Ag-Sn-Zn system of Pirquitas Mine.
Geology:
Whilst no intrusive structures are seen at surface it is evident that the Ordovician sediments are domed upwards around the old mine with upper formations highly altered and argillized and deeper formations comprising more indurated and partly silicified rocks closer to the mineralized zone. These formations plunge at shallow angles to the east, west, north and south and below the Crosby & Pirquitas Norte properties and have to be considered highly prospective at depths greater than those already proved up within the Pirquitas Mine.
Mineralization:
These properties surround the Pirquitas Mine where a stockwork system carries Ag-Sn-Zn of economic tenor and has recently been redeveloped into a producing mine. This stockwork system is developed around an anticlinal form which plunges northward, westwards, southwards and eastwards beneath the Crosby & Pirquitas Norte properties. Evidence of potential mineralization is seen at surface in a halo of alteration surrounding the Pirquitas mine, some of which passes on to these properties. If a continuation of mineralization is to be found it is inferred from this anticlinal form that this will be found mainly in depth.
