144 Ruby Silver Mines, Limited (Locality 32) References: Annual Report of the Minister of Mines, British Columbia, 1920, 1924 and 1925; Geol. Surv., Canada, Memoir 150. The property of the Ruby Silver Mines, Limited, is located on LeSueur (or Mosquito) creek which flows into Bear river just above the mouth of American creek. The country rock consists of black argillite with grey bands of quartz- ite, and is intruded by a dyke that follows the bedding. The rocks strike north-northwest and dip steeply northeastward. The mineral deposit is a quartz-sulphide vein in contact with the dyke. An adit at an elevation of 1,250 feet has been driven for a distance of 190 feet southeastward along the vein. The vein is 3 feet wide near the portal, but narrows and pinches out near the face. The mineralization is pyrite, galena, and sphalerite in a gangue of quartz and calcite. Rufus Argenta Mines, Limited (Locality 22) References: Annual Report of the Minister of Mines, British Columbia, 1916, 1920, 1922, 1924, 1925, 1928, and 1929. The holdings of the Rufus Argenta Mines, Limited, consist of the Rufus, Vetron, and Comet groups of claims which are north of Upper Bear river and west of the Red Top group. On the Vetron group, at an elevation of 3,000 feet, a 2-foot quartz vein is mineralized with pyrite, chalcopyrite, magnetite, and specularite. On the Comet group, at an ele- vation of 4,600 feet, a quartz-calcite vein up to 40 feet wide has been traced for several hundred feet. The vein contains galena and arsenopy- rite and picked assays have given 1-6 ounces of gold a ton. Another vein known as the “ Blue vein” is up to 18 inches wide and specimens from it assay up to 100 ounces in silver. On the Rufus group several large, rusty outcrops of rock are mineralized with pyrite and chalcopyrite. Two or more quartz veins up to 4 feet wide contain chalcopyrite, pyrite, and galena and a 2-foot vein containing tetrahedrite that carries good values in silver. An 800-foot adit has been driven, but no deposit of any importance was discovered. Rush-Portland Mining Company, Limiied (Locality 86) References: Annual Report of the Minister of Mines, British Columbia, 1910 and 1913; Geol. Surv., Canada, Memoir 32. The holdings of Rush-Portland Mining Company, Limited, are at the head of the north fork of Glacier creek. On the Katherine claim a quartz vein up to 5 feet wide contains galena, tetrahedrite, sphalerite, and arsenopyrite. The vein has been followed by an adit 110 feet long. In 1913 a shipment of twenty sacks of ore yielded $169 a ton, principally silver and lead.
