65 Mammoth Claim (45) The Mammoth claim is on the divide between Toboggan Creek and Silver Lake, at an elevation of 5,000 feet. It is on the south side of the new trail to the Silver Creek group above Schufer’s camp. A vein has been traced in voleanic rocks for 300 feet by four open-cuts. The vein strikes west and dips steeply south. At the most easterly cut the vein averages a foot in width and consists of pyrrhotite, arsenopyrite, and sphalerite, with a little galena. In the more westerly cuts the vein narrows to 4 inches and consists largely of quartz with considerable pyrite and a little chalcopyrite. Silver Creek Group (46) References: Ann.

There are six claims in the group, Copper Queen, Iron Mask, Texado, Lily Fraction, Iron Vault, and Van Anda. The property is reached from Smithers by motor road and a 4-mile long tractor road that was improved during the 1938 season by the Department of Public Works. The tractor road extends from elevation 2,400 feet at Toboggan Creek to the mine workings at elevation 5,500 feet. The mine camp is at elevation 4,700 feet, at the head of Toboggan Creek. The property was staked in 1908 by P. Schufer and L. Woods, following the discovery of pyrrhotite-sphalerite ore. Hudson Bay Mining Company bonded the group in 1910 and carried on development work until 1914. In 1917 the owners shipped 9,205 pounds of ore from a newly discovered deposit to the Trail smelter, which assayed: gold, 0:26 ounce a ton; silver, 246-1 ounces a ton; lead, 41-8 per cent; zinc, 18:8 per cent. The following year, a 30-ton carload of similar ore shipped to the Silver Standard mill for concentration averaged $175 a ton gross in all values. British Canadian Silver Corporation, Limited, explored the silver-lead occurrence in 1926 with a 200-foot drift; W. R. Wilson and Sons carried out further work during 1935 and 1936. On the Iron Vault claim, dark green and purple andesites with some interbedded tuffs are separated from a series of greenish tuffs by a band of fossiliferous limestone. The green tuffs pass upwards to the south into a thick formation of purple tuffs. The tuffs are mostly fine grained and massive, but some beds are well laminated. These bedded rocks strike easterly and dip from vertical to 50 degrees north. The top of the series is believed to be to the south, so that where the dip is to the north or northeast the strata are overturned. These rocks are intruded by a stock of granodiorite outcropping at the south end of the Iron Mask claim and extending westerly across the Copper Queen and Lily Fraction claims. The stock ranges from 400 to 1,000 feet in width and approaches 3,000 feet in length. The granodiorite is cut by a lamprophyre dyke 30 feet wide and dipping at a low angle to the south.
