The RD occurrence is located approximately 8.5 kilometres south-southeast of the village of Iskut and 2.0 kilometres east of Eddontenajon Lake. The property lies in a broad valley within the strongly dissected terrain of the Tanzilla Plateau.

The RD property is extensively covered by surficial deposits. The area is mapped as Lower Jurassic Hazelton Group consisting, in this area, of mainly andesitic volcanic breccias and conglomerates (Open File 1997-3). Near the showing, a fine-grained diorite of unknown age intrudes the volcanics. Potassium-feldspar and epidote enriched veining is common. Mineralization comprises chalcocite and malachite found along fractures.

The region was first explored in 1929 when copper mineralization was discovered on the nearby Hi property (104H 014) located 7.5 kilometres east-northeast. The RD property was briefly explored in 1977 by geological, geochemical, and geophysical means (Exploration in British Columbia 1977, page 228).

In 2005, a helicopter-borne geophysical survey was carried out on behalf of Firesteel Resources Inc. on the Rok property (104H 035) located 5.8 kilometres north. The survey comprised a new tri-directional magnetic gradiometer system, and a gamma ray spectrometer system. The airborne survey was flown at 200 metre line spacings with a total survey coverage of 611.4 line-kilometres.
