La Española Property ClaimsThe La Española Property is a copper prospect and is centered on an abandoned copper mine named Rosa Maria. It is located in the Coayllo District, Cañete Province, Department of Lima, in the Republica del Perú, about one hundred (100) kilometers straight-line distance, southsoutheast of Lima, the capital city of Perú. An initial NI 43-101 compliant report has been completed and available on the Grenville Gold Corp. website at:

In the area of the Rosa Maria Mine the rocks are mostly intermediate in composition and members of the Coastal Batholith. These rocks are cross-cut by intermediate to mafic dykes and sills. Emplacement of these dykes is controlled by a fracture and fault system that trends northnorthwest, three hundred thirty (330) to three hundred forty (340) degrees, dips sub-vertically, and that is concordant with and host to the Rosa Maria vein. The Rosa Maria vein is a quartz vein with carbonates hosting chalcopyrite, bornite, sphalerite, and magnetite and secondary copper oxides including chrysocolla, malachite, cuprite, and tenorite. All previous work performed on the Property targeted this vein. The style and form of mineralization fits a copper +/- silver quartz vein style deposit of the intrusion-related subtype.
The Phase I Exploration program is currently underway. It consists of small-scale geological mapping near the Rosa Maria vein and large-scale property wide mapping and sampling in order to identify new anomalous areas. The surface exposure of the Rosa Maria vein is being systematically sampled and some channel sampling has been done in the Rosa Maria Mine.
The La Española Property is a property of “Merit” and warrants further exploration. A two phase Exploration Program is recommended. Phase I Exploration includes geological mapping and sampling of the Rosa Maria vein, and Property scale geological mapping and sampling. Phase II Exploration will test the down-dip continuity of the Rosa Maria vein, and investigate new anomalies identified in Phase I Exploration.
A total of 45 grab samples of rock were collected from various underground workings with assays ranging from 70 parts per million to 11.37 per cent copper and 0.007 to 0.794 grams of gold/tonne. Mineralization on surface is hosted by steeply dipping malachite-stained quartz veins averaging between 0.5 to 3 meters wide. In the underground workings sulphide mineralogy consists of bornite and chalcopyrite. Results are consistent with the former producing Raul/Condestable Mines, located 15 kilometers west of Espanola. These mines are reported to have produced have produced over 20 million tons of ore grading 1.5% copper and 0.5 grams of gold per tonne. The average of the samples was 0.19 ppm Gold and 2.51% Copper.
