The Copper Ace property is located on a west facing, gentle slope of Granite Mountain, about 2 kilometres northwest of the Gibraltar Mines mill (093B 012) and extends out into the broad northerly trending Cuisson Valley. Road access to the property from Williams Lake is excellent and is gained by driving 45 kilometres north on Highway 97 to McLeese Lake, then east on Beaver Creek road (Gibraltar Mine road) for 13.7 kilometres, then 5.7 kilometres east and north on forest access roads to the gridded area of the property. Numerous secondary roads and trails traverse the property making most areas of the property easily accessible.

Discovered in 1998 by United Gunn Resources, the Rick showing, on the Copper Ace South grid, is about 4 kilometres northwest of the Gibraltar mine. Disseminated and fracture controlled copper and sphalerite mineralization occur in altered mine phase quartz diorite (chlorite-sericite schist) of the Early Jurassic Granite Mountain pluton. Assay values up to 1.5 per cent copper and 1.1 per cent zinc are common throughout the area (Exploration in British Columbia 1998, page A10).

A 2006 drilling program consisting of 3 holes for a total of 801 metres was conducted on behalf of Copper Ridge Explorations Inc. All holes intersected “Mine Series” tonalite, the main hostrock for copper mineralization at the Gibraltar Mine (093B 012). Mineralization included disseminated pyrite, variable amounts of disseminated chalcopyrite, minor sphalerite and traces of molybdenite. The mineralization is hosted in sericite altered and sheared intrusive rocks with quartz veins and veinlets. Alteration around the mineralization consists of weak to moderate development of chlorite, epidote and carbonate in the host tonalite. The drilling yielded significant results which include 3.43 per cent copper and 0.425 gram per tonne gold over 1.6 metres within a 72.4 metres interval of 0.09 per cent copper in drillhole CA-06-02 (from 63.4 - 135.8 m), and 0.11 per cent copper over 15.4 metres at the bottom of drillhole CA-06-03 (from 281.0 - 296.4 m) (Assessment Report 29283).

In the southern area of the Copper Ace South property, which is located to the northwest of Gibraltar Mines, limited exploration work has been carried out intermittently since the 1960s. In 1968, Morocco Mines carried out an induced polarization (IP) survey just to the south of the Copper Ace property, on ground now owned by Gibraltar Mines. To the south and west of the Copper Ace property several different types of geophysical surveys have been carried out in the area of the Sawmill deposit. Most of the results have not been reported. In 1998, 32 kilometres of grid was established, 550 soil samples taken and 29.0 kilometres of ground magnetometer and VLF-EM surveys were completed on the south part of the Copper Ace. In addition, 14 kilometres of induced polarization survey was completed. This work was carried out by Crest Geological Consultants Ltd. on behalf of United Gunn Resources Ltd. This work identified several strong copper, zinc and weakly anomalous molybdenum soil anomalies. In 2005, Copper Ridge completed a program of locating and re-establishing a portion of the 1998 gridded area, mapping and prospecting, rock sampling and completion of 8.4 kilometres of induced polarization and magnetometer surveys on six grid lines. The IP survey successfully extended the chargeability anomalies identified by the 1998 survey, while the geological mapping program confirmed the presence of the “Mine Series” tonalite extending northwesterly through the Copper Ace South property.
