The RB 15 showing occurs in a granodioritic pluton of the late Early Jurassic Cone Mountain Plutonic Suite. In 1990 rock samples taken of fractured granodiorite graded up to 1.08 per cent copper and 2.7 grams per tonne silver (sample Q52) and 0.65 per cent copper and 3.6 per cent silver from sample Q01, located about 300 metres northwest of Q52 (Assessment Report 21145).
Work History.
In 1970 Canadex Mining Corp. conducted soil sampling and geological mapping in the Dokdaon Creek area which resulted in the discovery of several quartz pyrite and quartz chalcopyrite veins associated with numerous northerly trending shear zones.
In 1971 the Swiss Aluminum Mining Co. optioned several claims immediately to the north of the Dokdaon property including the GU. They established cut grids and conducted soil sampling, a ground magnetics geophysical survey and hand trenched anomalous areas. They mapped the GU claims but did not discuss sampling.
Teck Corporation conducted a hand trenching and sampling program on the Dokdaon property in the area in 1981.
In 1989, the RB 15 and RB 17 claims were staked. During July of 1990, Razor 1 and Razor 2 were staked and the four claims were grouped under the name Dokdaon. In 1990 fieldwork was carried out on the Dokdaon property. A total of 49 rock, 24 soil and 8 silt samples were collected. The 1990 work by Schellex Gold Corp consisted of prospecting, surface sampling and geological mapping. Several rock samples assayed returned elevated values in copper, lead, zinc, gold and silver. A number of samples were taken just east of vicinity of the Gu North showing (104G 084) and some within a few hundred metres east of the Gu showing (104G 075) consisting of quartz-carbonate veinlets with sulphides gave significant assays (Figure 4, Assessment Report 21145).
Five main areas of interest within the BRC Property of Brades Resources Ltd covering a large area between Dokdaon Creek and Yeheniko Creek. For reference 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 (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.
