24 Strong silicification and deposition of some vein quartz Magnetite Pyrite Arsenopyrite Sphalerite Tetrahedrite Tennantite Unknown mineral resembling enargite Chalcopyrite Galena Chaleopyrite and arsenopyrite are the most abundant minerals, the others are present only in small amount. The shoots are small and are separated by barren material, but the veins are strong and there is no doubt that they contain considerable ore. GOLDEN WONDER PROPERTY. General Description. The Golden Wonder group is situated about 4,000 feet west of the Cap group and 1,200 feet lower; the elevation of the collar of the shaft is 1,290 feet. There are three veins on the property, the north, centre, and south veins; only the centre has been worked to any extent. The north vein is 12 to 15 inches wide and strikes north 85 degrees east (magnetic) with a dip of 75 degrees northwest. It follows the foot- wall of a 23-inch dyke of diorite porphyry which is also considerably mineralized with chalcopyrite, and has a 5-inch vein on the hanging-wall similar to the one on the foot-wall. The vein is filled with ground-up country rock together with quartz and tourmaline, containing pyrite, chalcopyrite, arsenopyrite, and a little pyrrhotite. The centre or main vein is 30 inches in width, strikes north 40 degrees east magnetic, and dips 80 degrees northwest. Besides stripping, a shaft is being sunk on the vein and was down 32 feet when examined. Near the top there was a considerable amount of chalcopyrite in a solid mass, but this passed into lower grade material much higher in arsenical iron carrying a little gold. Work is being continued to give the property a fair test. The southern vein is exposed near the road and parallels the centre vein at about 300 feet distance. A shaft sunk 25 feet shows approximately 2 feet of pyrrhotite with a small amount of chalcopyrite which carries a little gold; the shaft has been abandoned, but the showing warrants further investigation. Paragenesis. The tuffs here have been fissured and highly sericitized near the fissures. Silicification followed and quartz replaced nearly everything except the sericite. Tourmaline then replaced the quartz, so that both vein material and wall rock are high in tourmaline. Table of Paragenesis of the Ores from the Golden Wonder Property. Magnetite Arsenopyrite {Pyrrhotite Chalcopyrite Marcasite A later introduction of quartz was followed by the formation of Siderite Limonite The exact position of the marcasite in the paragenesis could not be determined with certainty. ona pee
