Main Ridge Project, Jamaica
The Main Ridge Project (MRP) consists of a wholly-owned Special Exclusive Prospecting License (SEPL) covering 30 sq. km. MRP is located within the west-central part of the highly tectonized altered and mineralized Cretaceous Central Inlier (Map 1). The Spaniards mined placer gold in the 16th Century within the Central Inlier. Limited exploration has been completed to date at the MRP.
The geologic history of subduction, crustal thickening and tectonism has produced extensive mineralization within areas of Cretaceous rock throughout the Caribbean (Map 2), such as at the Pueblo Viejo deposit, which contains more than 36 million ounces of gold and 930 million pounds of copper.
Exploration and prospecting, namely soil sampling and limited prospecting by BHP and others, during the 1990s demonstrate the excellent potential at MRP for economically-viable epithermal gold and gold-copper porphyry and oxides deposits. A Canadian International Development Agency (CIDA) stream sediment sampling program indicates the presence of gold and copper in the Main Ridge area. (Gold Map 3a and Copper Map 3b).
BHP discovered a 6 km structurally-controlled gold in soil anomaly which crosses the MRP (Map 4). This anomaly also crosses the Pennants gold mine, a high grade (Jorc Resource 94,400t @ 13.9g Au/t) small mining operation. The deposit at Pennants is open at depth and along strike.
A broad copper in soil anomaly is located over the crest of Main Ridge suggesting that it is underlain by a significant sized copper porphyry. High copper soil values and rock samples (0.84% Cu over 1 m) in the volcanic agglomerates flanking Main Ridge (Map 5) indicate the potential for a large oxide deposit.
Carube plans to concentrate on (1) determining the extent of the epithermal gold mineralization and (2) the extent and grade of the copper porphyry and oxide mineralization.
