The Tooz occurrence is located near Toozaza Creek, about 35 kilometres northwest of the townsite of Cassiar.
The showing area is underlain by metasediments and carbonates aligned against the contact with granodiorite and biotite quartz monzonite of the Early Cretaceous Cassiar batholith. This contact trends northwest through the eastern portion of the claims. The sediments and carbonates are likely part of the Tournaisian (lower Early Mississippian)-Permian(?) Sylvester allochthon. Graphitic shale occurs in contact with the batholith. A series of northwest trending interbedded mudstone, limestone, argillite, greywacke and metawackes occur westward from the contact. Isolated interbeds of dolostone and fetid limestone, likely of the Middle-Upper Devonian McDame Group are also present. The beds range from 1 to over 5 metres in thickness.
Mineralization was found on a northwest-facing slope above Toozaza Creek and is hosted in a sequence of carbonate and metasedimentary interbeds. It occurs as massive galena and sphalerite conformable to bedding in near-vertical carbonate beds at contacts with the adjacent metawackes. The main exposure measures up to 20 centimetres in thickness, pinching and swelling over an exposed strike length of 6 metres, dipping steeply into the hill. The outcrop is buried under talus above and below. Other minor occurrences can be found along the hillside for approximately 50 metres. Contact between the mineralized carbonate with the metasediment is abrupt with no disseminated mineralization found in the adjacent wackes.
Lead and zinc results from rock sampling by Cominco in 1997 exceeded calibration of instrument for geochemical analysis and should be submitted for assay (Assessment Report 25342).
In 1996, the Tooz claims were staked to cover an anomalous zinc and lead drainage reported in a 1978 Geological Survey of Canada regional sediment sampling program. In 1997, Cominco Ltd. conducted prospecting and contour soil sampling.
