LO One good width of low-grade ore has been intersected in a diamond drill hole on Silver Creek. The cinnabar is in cherty limestone and carbonate-quartz-mariposite rock at the contact of limestone with al- tered serpentine. At the north end of the stripping along Silver Creek, a bed, 10 feet. thick, of rusty Tertiary gravel has been uncovered. This gravel rests on bedrock and.is overlain by boulder clay. Boulders of rich cin- nabar ore occur in the gravel. Some. of. these are as much as 2 feet in diameter. The source of this float is unknown, but if the Tertiary gravel represents an old channel of. Snell Creek the source is farther up this channel, Bron Group The Bron group lies between the west fork of Kwanika Creek and Bralorne Takla mine, and may be reached by trail from this mine. It is owned by Consolidated Mining and Smelting Company » Except: for one small sill of greenstone, the only bedrock ex- posed on the claims is Permian limestone. This is the normal grey variety containing numerous solution cavities up to 3 feet across and patches of coarsely crystalline calcite. In most places it has been brecciated along fault planes and partly altered to dolomite. Commonly the fragments of the breccia are grey limestone, and the cement is buff dolomite. On the west forkof tar Creek the breccia zone is 125 feet wide. The Pinchi fault zone traverses the group from north to south and includes all the exposed limestone. ‘The eastern border of: the lime- stone outcrops forms” @ scarp and Ise Ae Atay HONS ide eastern margin of the Pinchi fault zone. Cinnabar’ is exposed in a mineralized zone 10 feet wide on the west fork of Kwanika Creek. It occurs as minute crystals in brecciated limestone and as films on slip surfaces. Diamond drilling failed to re~ veal any cinnabar at depth. ' Lil Group The Lil group, owned by the Consolidated Mining and Smelting Company, joins Bralorne Takla holdings on the north and is crossed by the road to that property. The group consists of sixteen claims, but work has been confined to the "Til" No. 15, immediately north of the Bralorne property. The only rock outcropping on the group is Permian limestone, and at most places it is brecciated. The limestone lies in the Pinchi fault zone, which crosses the property from north to south. The eastern margin of the zone is drift covered and one drill hole penetr
