23 it is confined to the arsenic minerals. Associated with the gold in grains similar in size and shape to the gold grains, occurs another mineral varying from yellowish cream to creamy white in colour, which is thought to be electrum, but as yet is not definitely identified. The gold in arsenopyrite and safflorite is shown in Plate VIIB. Some gold was found occupying minute veins in the arsenopyrite and was, therefore, deposited some time after the arsenopyrite.

Faulting, with throw of 11 feet Sericitization and development of abundant actinolite Silicification and replacement of other minerals by quartz Magnetite Pyrite Arsenopyrite, safflorite, léllingite Gold Molybdenite Calcite _ The gold may have been contemporaneous with the arsenopyrite since it is always embedded in that mixture; the molybdenite comes later than the arsenopyrite mixture. The actinolite in several sections appears to be later than the molybdenite; itis probable that the development was in two stages or was continuous during the first mineralization. There appears to have been some fissuring, with a deposition of silica at some time between the deposition of arsenopyrite and the deposition of molybdenite; this is well shown in Plate VIIIA. PRESTON PROPERTY. (General Statement. Going west from the Hazel- ton View workings, down the mountain, at elevation 2,850 feet, is the Huckleberry claim which contains a fissure 34 to 4 feet wide striking north 80 degrees west (magnetic) and dipping 69 degrees to the southwest. A stripping exposes this vein for 150 feet through coarse tuffs. The filling is mostly crushed country rock with some pyrite and arsenopyrite, carrying a little silver and gold. CAP PROPERTY. General Description. The Cap group is situated at 2,200 feet elevation, practically on the strike of the Hazelton View veins, distant 9,000 feet horizontally and 3,000 feet vertically. It has been opened up by strippings, by a 60-foot shaft, and by two short crosscut and drift tunnels. The vein is 18 inches to 5 feet in width and cuts crystal tuffs which have been mistaken for granodiorite. The gangue is mostly of crushed and altered wall rock with some quartz. The ore is valuable for its silver and copper, and carries a little gold. _ At 20 feet down the shaft a sample across 2 feet of the vein gave: gold, 40 cents; silver, 9-8 ounces; copper, 1 per cent.! At 10 feet in the shaft a sample across 2 feet of ore gave: gold, 0-04 ounce; silver, 21-4 ounces; copper, 7-5 per cent.! A sample of 5 or 6 tons of the best ore from the upper 20 feet of the shaft gave: gold, $1.20; silver, 25-2 ounces; copper, 9-7 per cent.! The first tunnel came in 40 feet below the collar of the shaft, and passed through a small shoot which is seen on the surface and in the shaft; a sample of 20 tons of the best ore from this shoot, taken from the tunnel, gave: gold, 0-03 ounces; silver, 10 ounces; copper, 8 per cent. Solid arsenical iron assayed: gold, 0-14 ounce; silver, 10-5 ounces.! Table of Paragenesis of the Ores from the Cap Group.
