The Gazoo (Central Stock) occurrence is located near the confluence of Iverson and Toozaza creeks in the Cassiar Mountains of northwestern British Columbia, about 133 kilometres north of the community of Dease Lake.

A 750-metre-long stock of biotite-muscovite quartz monzonite intrudes foliated biotite quartz monzonite of the Early Cretaceous Cassiar batholith and is locally cut by quartz veins. Four small plugs of porphyritic quartz monzonite intrude the stock. The contact between the foliated intrusion and the stock is faulted. One of the contact/faults trends northwest and contains fluorite, calcite, chalcedony and quartz-pyrite-sericite veins and breccia and gouge zones up to 15 metres wide. Molybdenite and chalcopyrite occur in quartz-pyrite veins, in fault breccia zones, and as disseminations in the host intrusions. A large northeast trending fault zone is the locus of intense argillic-sericitic alteration.

In 1978, Amax Potash Limited conducted geological mapping and collected a total of 406 soil, silt and rock chip samples from within the claims area. A 10 metre rock chip sample (BTM 868b) from the Ridge showing assayed 0.064 per cent MoS2 (Assessment Report 7148). The Ridge showing is located 370 metres southeast of the Central Stock showing.
