28 adit would have to be continued somewhat over 100 feet to intersect the downward continuation of the dyke. A grab sample of the silicified dyke rock carried neither gold nor silver. At elevation 2,280 feet, on a steep, rocky slope cleaned by annual snow slides, a large open-cut in andesite discloses numerous, small, inter- secting faults and joint planes. Chalcopyrite with pyrite and a little galena occurs in narrow seams along the faults and joints, and the bordering andesite is replaced by small veinlets of the sulphides. The ore zone 1s about 4 feet wide, but gives no promise of continuity along its strike as it passes gradually into almost barren andesite a short distance above and below the cut. A selected sample assayed: gold, a trace; silver, 0-84 ounce a ton; copper, 2-16 per cent. A very similar occurrence of chalco- pyrite and pyrite along fault slips and joint planes in the andesite is exposed in a second open-cut about 100 feet farther northeast along the mountain side. Again the ore zone has indefinite boundaries and lacks continuity. "The trail continues to an elevation of 3,000 feet where there is a dyke- like body of fine-grained, brownish purple albite andesite, which strikes east and dips 65 to 70 degrees north. The north contact of this dyke or flow has been stripped for about 60 feet and a trench 14 feet long blasted into it to expose six or seven parallel fractures, about 15 inches apart, which contain vein fillings of quartz, calcite, and bornite, with a little chalcocite. The bornite veins range from 1 to 8 inches in width with an average width of 4 inches, but they do not appear to continue along their strike for over 50 feet. ‘The mountain slope in the neighbourhood is mostly drift covered and unprospected. A typical sample collected from the ore dumps assayed: gold, a trace; silver, 9-64 ounces a ton; copper, 19-10 per cent. About 1,000 feet northeast along the mountain from the two cuts mentioned above an adit at elevation 2,300 feet, which is reached by a separate trail from the creek below, has been driven 270 feet in a south- east direction in andesitic lavas. Several intersecting and steeply dipping fault slips were drifted along and several inches of quartz calcite gangue occurs at intervals in the fault gouge, but no ore was found. The adit was driven with the intention of intersecting the downward continuation of a quartz-albite dyke that outcrops on the east side of a steep-walled ravine cut by a small mountain stream at elevation 2,700 feet. The dyke is 12 feet thick, strikes south 10 degrees east, and dips east at 45 degrees. The hanging-wall side of the dyke is bordered by a 14-inch quartz vein, containing about 2 per cent of chalcopyrite and bornite. At about 2,500 feet elevation the dyke crosses to the west side of the creek and pinches out. Where the dyke narrows before pinching it is altered and impregnated with a little chalcopyrite. A 14-inch channel sample across the vein assayed: gold, 0-02 ounce a ton; silver, 5-98 ounces a ton; copper, 1-16 per cent. Shenandoah Group (19) Beene Ann.
