The YRD showing is location along the International boundary, 16 kilometres west of the Similkameen River and 6.75 kilometres southwest of Snowy Mountain (Minister of Mines Annual Report 1968, page 220).

The YRD and URP claims were staked and explored in 1968 by Phelps Dodge Corp. of Canada Ltd. No assessment work was filed providing information on their exploration program, consisting of geological mapping, and geochemical rock and soil sampling.

The showing is hosted by the Middle Jurassic Similkameen batholith. Molybdenite and minor chalcopyrite and pyrite are hosted in quartz veins and disseminated in fractured quartz monzonite (Minister of Mines Annual Report 1968, page 220).

Molybdenite is widespread elsewhere in the Similkameen batholith. Minor molybdenite, chalcopyrite and galena were found to the northeast near Snowy Mountain on the OK 1 to 14 claims by Cominco in 1980 and 1981 (Assessment Reports 7908, 8579).
