The ROY showing is located north of Lambly Lake, approximately 15 kilometres north-northwest of Westbank.
The showing was explored for copper in 1970 by the Cariboo Gold Quartz Mining Company Limited. Work consisted of magnetometer and geochemical surveys, 90 metres of trenching and 1 diamond-drill hole. In 1973, linecutting and a ground magnetometer survey was carried out by Wharf Resources Ltd.
The showing is underlain by greenstone of the Devonian-Triassic Harper Ranch Group, which in turn, is overlain to the southeast by trachyte to trachyandesite flows, ash flow tuff and minor mudstone of the Eocene Kitley Lake Formation. An altered volcanic of intermediate composition and rich in titaniferous magnetite was intersected between 112 metres and 161 metres depth in the diamond-drill hole.
