Vein hosted in Upper Triassic Stuhini Group mauve, plagioclase-rich volcanic wacke. Subrounded volcanic and rare limestone fragments supported in a volcanic matrix. The discontinuous quartz-carbonate vein is zero to twenty centimetres thick and contains chalcopyrite, galena, pyrite, and malachite.

The area was mapped in 1990 by the British Columbia Geological Survey and the Muffle was documented.

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. 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.
