Mount Angelo Porphyry Copper Prospect
The Mt Angelo Porphyry Copper Prospect (80% 3D Resources) represents a large low grade porphyry copper deposit based on drilling carried out by Pickands Mather and Murchison Central Mines in the late 1960s and early 70s. The mineralisation occurs as stringers and veinlets of chalcopyrite and various secondary copper minerals within a granophyric microgranite host straddling the Olympio Formation – Koongie Park Formation contact.
The gold, silver and molybdenum potential of the porphyry was not fully investigated by the previous explorers. Diamond drilling in the late 1960s produced significant intercepts up to 152 m grading 0.54% Cu and strongly anomalous Mo values (up to 2000 ppm). Grab sampling of later shallow percussions drill holes over the same mineralised zone has returned encouraging values of 1.3% Cu associated with weakly anomalous Au (13.4 ppb Au).
The mineralised zone occurs within an extensive 1000 m long by 300 m wide soil geochemical anomaly that has not been tested by modern deep drilling RC techniques. The Company has located mineralised quartz veins and breccia samples within the anomalous geochemical zone containing values up to 3.2% Cu, 5.5 g/t Ag and 68 ppm Mo.
