Orestone Mining has announced that it is advancing the ongoing development at the Captain porphyry project, which contains gold and copper. This project is situated 43 km towards the north of Fort St. James in British Columbia and around 30 km towards the southern part of the Mt. Milligan deposit.
The company has chosen representative core samples from the drilling program, completed recently, and sent for microscopic petrographic test. These samples from hole C12-01 have been subjected to the petrographic analysis and the results have been obtained. These samples have demonstrated a pervasive alteration assemblage of carbonate-pyrite-sericite-quartz over around 250 m down hole. This has shown that the drill hole cut the pyritic halo in the outer part of phyllic shell located around a porphyry system’s border. Testing of samples from the hole C11-01 is pending. Carbonate-potassic-sericite altered volcanics were identified in the hole C11-01 grading 0.025% copper and 0.230 g/t gold over 85 m. The occurrence of mineralized gold and copper-gold together with the hole’s increased potassic alteration is analyzed to show better potential towards the east.
Strongly altered and dispersed sulphide zones related with the altered monzonite intrusive is tested to enclose an area of 7,000 x 7,000 m, based on the completed drilling and geophysics program, and has shown a huge porphyry system. The company’s primary 1,150 m of drilling, totaling four holes, examined only a small segment of a huge IP anomaly target.
