The Numa claims are located on a ridge seperating the Conuma and Tlupana rivers, south of Conuma Peak and approximately 6 kilometres north east of Nesook Bay.

The area is underlain by diorite and granite of the Jurassic Island Plutonic Suite. These plutonic rocks intrude volcanics and sediments of the Upper Triassic Vancouver Group, Karmutsen Formation and the Pennsylvanian to Permian Sicker Group (Geological Survey of Canada Map 1537A).

Molybdenite is found over an area of 1000 by 700 metres in tight joints and fractures and along k-feldspar altered quartz-vein margins in intrusive rocks. Some chlorite and epidote alteration is present in fractures.

The area of mineralization is slightly pyrite enriched.

From 1980 to 1981, the four Numa claims were staked by Umex to cover an area of anomalous concentrations of molybdenum in stream sediments. From 1981 to 1985, Umex completed various exploration programs of geological mapping, goechemical surveys and an induced polarization survey.
