The region of the occurrence is underlain by Early Jurassic granodiorite of the Cone Mountain Plutonic Suite which has intruded Upper Triassic volcanics and sediments of the Stuhini Group. A roof pendant of volcanic breccia about 600 metres long and 300 metres wide extends northeast from Dokdaon Creek.

The Creek Showing is a 0.3 to 1.5 metre wide quartz-carbonate breccia/shear vein in granodiorite. Parallel to the vein a mafic dike and a tan rhyolite dike have intruded and healed the shear. It is situated at the 950 metre level on the east bank of Dokdaon Creek. It appears that recent meandering and subsequent relocation of the creek bed has removed the covering overburden and partially exposed the showing. Although still relatively poorly exposed, it can be traced intermittently for an estimated distance of over 200 metres where it is lost at both ends under overburden.

Locally, the total sulphide content of the vein is estimated to be approximately 3 per cent and consists of disseminated pyrite and sphalerite (+/- galena). A pod of massive sphalerite and galena measuring 0.3 by 0.5 metre was noted. The total width of the mineralized zone is nowhere fully exposed; however, although the zone is lenticular, the maximum width is estimated to be at least three metres. The average width is estimated to be less than 1.0 metre.

In 1990, several trenches were cut across this structure. Several chip samples taken across the vein yielded very low gold values (to a maximum 100 parts per billion). Along local shearing parallel to the main breccia vein, actinolite-magnetite-pyrite mineralization has formed. Generally the width of these structures is less than 1 centimetre on the walls of the shear; however, locally they swell to over 15 to 20 centimetres where chalcopyrite and malachite mineralization is present. Samples from this shear zone (103262, 102912) yielded up to 2.16 (Assessment Report 20713).

Work History

The Marg East (104G 089) showing was originally located by prospectors working for Silver Standard Mines in 1957. Teck Corporation restaked, sampled and mapped the showing in 1980-81. At this time sampling and mapping of the adjacent Marg West (104G 089) showing was also undertaken. The Marg West showing is on the adjacent property (Canyon 24 claim) held by Homestake Mineral Development Company. This property was examined briefly in 1989. There is no record of any other work having been done in the immediate vicinity of the Ambition I and II claims in 1990.

In 1990, the owner of the Ambition claims was Goldbelt Mines and the operator was West Sea Development Corp. West Sea collected a total of 90 rock and 7 silt samples. They examined the Marg East claims and found the Creek and Morraine showings

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 (104G 089) showings (Assessment Report 30029). 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.
