Castle Rock Resources is active in Chile through the acquisition of Andina Minerals Inc. in the fall of 2004. Their prime Mexican holding remains Quitovac that is currently being explored through a JV with Copper Ridge Explorations.

Quitovac, Sonora. The Quitovac Property is located approximately 45 kilometres south from the town of Sonoyta near the Arizona/Sonora boundary and consists of 13 contiguous land titles (both exploitation and exploration), covering 2,484 hectares. The principal period of exploration and mining activity at Quitovac occurred during the late 1800's to early 1900's. Both hard rock and dry placer operations were in operation during this period. Limited underground work is believed to have occurred again during the 1950's. Within the district, small-scale dry placer operations have continued intermittently to the present. The main exploration efforts at Quitovac (for which there is documentation) were in the 1980's, when Servicios Industriales Peñoles S.A. de C.V. ("Peñoles") conducted a reverse circulation-drilling program, which consisted of 63 holes for a total of 6,300 metres. Santa Cruz Gold obtained the ground in the mid-1990's and conducted a resource study based on the Peñoles data. They defined an "in-house" resource of 3.3 million tonnes at an average grade of 1.35 g Au/T for the immediate Quitovac area. Santa Cruz conducted a 20-hole reverse circulation drilling program within the immediate area and carried-out a resource study based on their drilling results. They defined a resource of 1.1 million tonnes at an average grade of 3.14 g Au/T. The property has essentially remained idle since that time. In the immediate area of the old workings, the strike direction of the main thrust is generally east-west and appears to continue this way to the west of the workings. East of the workings, the thrust appears to join up with a northerly-trending thrust and quickly changes attitude to north-south and continues in a southerly direction through most of the claims. The dip of the thrust remains at 40-60 degrees to the west for most of its length within the claims. The geological model is robust and adaptable as more is learned from future exploration. The current level of data and understanding and the methodology and assumptions employed for the resource estimation appear to be appropriate.
