The YHW-1 showing is located between Ptarmigan Creek and the Fraser River, approximately 20 kilometres southeast of the community of Dome Creek.

The area is underlain by Cambro-Proterozoic clastic and carbonate Midas Formation rocks. These consist of grey phyllite with minor schist. The phyllite is crosscut by veinlets, blebs and wisps of quartz-calcite or ankerite ranging from a few millimetres to 3 centimetres in thickness and commonly paralleling the cleavage.

The Yanks Peak Formation overlies the Midas rocks to the west. The Yanks Peak rocks are comprised of sandstone, quartzite, and pebble conglomerate. They host disseminated pyrite and are crosscut by a series of quartz veins.

The claims were first staked in 1985 by Noranda Exploration Company. The following year a brief program of rocks, soil and silt sampling was completed. In 1987 and 1988, trenching surveys and a combined VLF-EM and magnetometer survey was completed.

In 1986, chip samples taken from the phyllite exposed along a rock cut assayed 1.8 grams per tonne gold. The phyllite hosts a predominant set of veinlets which crosscut the bedding at right angles. Detailed 1 metre chip samples assayed 0.28 and 0.23 gram per tonne gold (Assessment Report 15463).
