The Canyon 24 area is underlain by volcanic rock of the Upper Triassic Stuhini Group which is intruded by a granodioritic stock of the Late Early Jurassic Cone Mountain Plutonic Suite.
Numerous quartz pyrite veinlets and stringers were noted along regional fracture planes within quartz diorite. The veinlets average three to five centimetres in width and trend 030 to 070 degrees. Veinlet density varies from 1 or 2 per metre up to 10 to 15 per metre. The zone of veinlets is approximately 200 meters wide and was traced up slope to the toe of the glacier. The veinlets are generally tight with little evidence of wallrock alteration.
One 10 centimetre wide vein was traced for a strike length of 100 meters before it was lost under talus. The vein contained 5 per cent galena, trace molybdenite and a trace tetrahedrite. A sample assayed 4.11 grams per tonne gold, 1896.36 grams per tonne silver, 0.11 per cent molybdenum and 3.09 per cent lead (Assessment Report 20150).
The Canyon 24 area occurs within the southeast corner of the BRC property of the 2000s.
Work History
In 1989, work on the Canyon 24 claim involved 1:10,000 scale mapping as well as the collection of 4 rock and 6 silt samples (Assessment Report 19062). In 1990, Homestake Mineral Development Company prospected the Canyon 24 claims which covered some of the Marg area worked previously by Teck (Assessment Report 20150). A total of 23 rock samples were collected from zones of alteration and mineralization. Several samples were taken in the Marg West (MINFILE 104G 058) and Marg East (MINFILE 104G 089) areas.
In the late 2000s, five main areas of interest within the BRC Property of Brades Resources Ltd covered a large area between Dokdaon Creek and Yeheniko Creek. These are referred to as the Dok 35 area, the Teck Area, the Yeti Area, the Strata Creek Area, and the Yehiniko East Area. BRC carried out a preliminary exploration program in the fall of 2007 consisting of airborne geophysical surveys and a limited program of verification sampling. Airborne surveys were carried out by Fugro Airborne Surveys primarily in the Strata Creek area and verification sampling was carried out in the southwestern part of the claim group in the area referred to as the Teck area that contains the Marg West (104G 058) and Marg East (MINFILE 104G 089) showings. In 2010, Brades Resources completed detailed digital topographic maps of the Teck and Yeti areas and compiled all historic rock, soil and stream sampling data for the entire BRC Property. Later in 2010, Brades conducted detailed topographic mapping to cover additional parts of the BRC property and several helicopter assisted site visits were completed to verify mineralization reported in the central part of the BRC property. A total of 24 rock samples were collected. In late 2010 to January 2011 a detailed structural analysis of the Teck area and the Yeti area was carried out using shaded hillside imagery technology.
