westward through the breadth of the 30-foot long artificial rock face. Near the tunnel a small amount of pyrite is visible. At the tunnel entrance, the mineralized zone in the quartzites is formed of small, angular frag- ments of country rock lying in a matrix of hematite and quartz. In places the matrix preponderates, in other places the rock fragments are in excess. The individual fragments are usually traversed by veinlets of hematite and quartz and in some cases the veinlets are so numerous that the rock fragments appear as an aggregate of grains separated from one another by films of hematite and quartz. A hand specimen will exhibit all gradations from solid, angular rock fragments an inch or so in diameter and separated from one another by narrow seams of hematite, to other fragments now resolved into minute pieces, and, finally, to areas of hematite several inches in diameter but carrying innumerable minute grains which seemingly represent remnants of a once solid and comparatively large rock fragment. Towards the west, the breccia-like appearance gradually dies away and at the west edge of the rock face the quartzite is compact and only sparingly traversed by minute, approximately vertical seams of hematite and of hematite and quartz. Nowhere in the rock face does the hematite constitute an ore-body and, judging from the materials on the dump, no body of ore was penetrated by the tunnel. The mineral-bearing zone appears to be nearly vertical and its strike is south-southwest judging by the occurrence of a small outcrop of similarly altered and impregnated rock visible 60 yards farther south and 80 feet higher up the slope.

On the Union Jack claim, on the east slope of the ridge, 300 yards east of the above-described exposure, are outcrops of another zone of igneous and sedimentary rocks seamed and impregnated with quartz and hematite. In this instance the zone is continously exposed over a length of 300 feet and at intervals for 300 feet farther. The strike is a little west of south and the dip appears to be at very high angles to the west. The exposures occur along the edge of a drift-covered area stretching sxastward down the hill-side and both to the north and south, the outcrops disappear under soil. The width of the exposures varies and much of the outcrop consists essentially of silicified country rock traversed by quartz veins and seams of hematite. The greatest exposed width is 55 feet and at this point, commencing at the eastern drift boundary, the zone for a breadth of 10 fect consists of a dark igneous rock veined with quartz and hematite. For spaces of a foot or so, the igneous rock is fairly free from quartz or hematite, and alternating spaces are largely of vein quartz, or of hematite, or of a mixture of the two minerals. In the next 10 feet to the west, the igneous rock gives place to altered quartzite with several zones, 1 to 2 feet broad, largely of hematite veined with white quartz. The next 15 feet is of altered quartzite with zones heavily impregnated with hematite through which quartz occurs both in irregular veins and in disseminated grains. The remaining 20 feet along the west side of the exposure and presumably close to the west boundary of the zone is of altered quartzite cut by many quartz veins and with, here and there, thin seams of hematite. In general the amount of hematite decreases from east to west and nowhere is a body of hematite ore of any size exposed.

About midway between the outcrops on the Union Jack and Golden Cap claims several shallow trenches on the Jolly Boy claim reveal miner- alized strata such as oceur on the Union Jack location, but poorer in hematite contents.
