Feb 06, 2018 (Therese Pettigrew) - Two nearly parallel composite veins near the middle of lot 19, concession IV, Paipoonge township, were located by Mr. Parsons who, it is reported, mined some few tons of ore averaging 1,000 ounces of silver a ton. The north vein has been exposed by cross trenches at intervals of 20 feet, for a distance of 120 feet. A shaft, 15 feet deep, has been sunk at the west end of the workings. On the south vein, 60 feet south from this shaft, there is a second shaft 50 feet deep. Stripping extends for distances of 40 feet along the south vein on either side of the shaft. The composite veins seal shatter zones in grey, flat-lying Animikie shale. The north vein strikes south 72 degrees east, dips vertically, and has a width of about 3 feet. The vein material constitutes about one-half of the volume of the cemented shatter zone and is almost entirely confined to two veins, each 8 inches to 10 inches wide, separated by 1.5 feet of shale which here and there is penetrated by ramifying quartz stringers. One of the 8 to 10-inch veins consists chiefly of coarsely crystalline calcite, whereas the other is almost entirely colourless and pale amethystine quartz. The south vein has an average width of 12 inches and contains little brecciated country rock. It trends south 63 degrees east and dips vertically. The vein material is predominately coarsely crystalline calcite. The gangue minerals that are common to both veins, in addition to those mentioned, are rose quartz and green fluorite. Metallic minerals make up between 2 and 3 per cent of the vein material. They include light-coloured and black sphalerite, galena, pyrite, marcasite, and leaf argentite (Tanton, 1931). In 1936, ore from the new shaft was shipped to the Temiskaming Testing Laboratories at Cobalt. A total of 5060 pounds of ore was shipped, yielding 2200 oz Ag (Sinclair et al., 1937).
