29 An adit has been driven westward toward the open-cuts from the Barkerville road a few hundred feet north of Barkerville. The adit is 2,000 feet long and penetrates through the lower part of the Barkerville formation into the Baker member of the gold belt. Quartz veins are rare in the adit but some occur and one 1,000 feet from the portal contains pyrite and near the vein limestone has been replaced by pyrite and black sphalerite. Several strong fractures cross the adit 500 feet from the portal. They strike northeast and are branches of a northeasterly striking fault. SIRIUS CLAIM The Sirius claim is on the eastern slope of Barkerville mountain a short distance northwest of Barkerville. The claim is underlain by fissile grey quartzite of the Baker member intruded by two or more sill-like bodies of quartz porphyry. An open-cut at the B.C. ditch, about 50 feet south of the southern boundary of the Progress No. 8 claim, exposes a body of quartz porphyry holding a quartz vein 1 to 5 feet wide and many irregular quartz veinlets. About 200 feet east are two other open- cuts, both in quartz porphyry holding much quartz in irregular veins. WESTPORT, BLACK JACK, DILLER, AND BLACK JACK EXTENSION CLAIMS The claims listed above extend from Barkerville to the south and cover the junction of Williams creek and Stouts gulch. The Diller claim is underlain mainly by grey calcareous quartzites of the Baker member. The Westport claim is underlain mainly by quartzites of the Lowhee mem- ber, and the other two by argillites and quartzites of the Rainbow mem- ber. A number of quartz veins are exposed on Williams creek on the Westport claim and in 1933 the Britannia Mining and Smelting Com- pany drove three short adits on this claim, northwestward from Williams creek. Two of the adits are only 10 to 20 feet long. One crosscuts a 2-foot quartz-pyrite vein striking north 70 degrees east and both expose several quartz-pyrite veinlets striking north 70 degrees east. The third adit is 250 feet long and crosses several parallel quartz stringers striking north 25 degrees east and five quartz-pyrite veins each from a few inches to 24 feet wide, striking north 15 to 35 degrees east. An open-cut in the southwest corner of the Black Jack claim exposes three veins striking north 60 degrees east, south 80 degrees east, and south 30 degrees east. The north 60 degrees east striking vein is 2 feet wide. A short adit nearby cuts many quartz veins from 1 inch to 2 feet wide very well mineralized with pyrite. Near the northeast corner of the claim another adit driven by the Britannia Mining and Smelting Company in 1933 is 160 feet long. A large shallow pit at the portal of the adit exposes many parallel quartz-pyrite veins a few inches to 1 foot wide striking north 60 degrees east and making a vein zone 50 feet wide. Early reports state that 200 tons were mined from this pit and a shaft. The adit crosscuts another group of parallel veins striking north 50 degrees east and extending across a width of 25 feet. There are also several narrow bed veins at this place. In the northern corner of the Black Jack Extension claim and on the southern part of the adjoining Diller claim are a great many quartz veinlets 97192—3
