Mining News: 6.75 oz/t gold sample at Herbert
Grande Portage Resources Ltd. Sep. 6 announced that sampling of a newly exposed outcrop at its Herbert Gold project about 15 miles (25 kilometers) north of Juneau, Alaska , returned 6.75 ounces per metric ton gold. This outcrop of the Goat vein was exposed by the rapid erosion of loose boulders and gravel. The vein here consists of approximately 4 feet of quartz with disseminated arsenopyrite, pyrite, galena and sphalerite and visible gold. Hanging wall alteration of the quartz diorite host rock reaches width of at least six feet and the footwall contact zone is covered in the creek bed. A Grande Portage geologist hammered numerous representative grab samples over a four-foot width of the exposed Goat vein. The assay results from this sampling returned 231 grams per metric ton (6.75 oz/t) gold and 49.8 g/t silver. The company has completed roughly 75 percent of 3,700-meter summer drill program designed to extend three separate major veins and their satellite structures at Herbert Gold. Ten holes have now been completed from three drill pad locations. The majority of these holes were designed to expand the strike length of Goat, the northernmost drilled vein, and to also intercept the Main vein. Grande Portage said all holes have good visual indicators, including quartz with disseminated arsenopyrite, pyrite, galena and sphalerite and visible gold. Assays are pending. "We are extremely pleased to have defined a substantial increase in the mineralized strike length located in the eastern test areas, and to confirm the mineralization at depths beneath previous drilling,” said Grande Portage CEO Ian Klassen.
