The Tat group of claims are located east of Tatin Lake, 6.5 kilometers north of the community of Endako.
Locally, rocks of the Simon Bay diorite complex are overlain by Tertiary Endako Group lavas. Casey quartz monzonite, a phase of the Topley batholith, is exposed in the extreme western portion of the claims, near Tatin Lake.
A large induced polarization anomaly, 3000 by 450 metres, was identified on the property and is likely related to pyrite +/- molybdenite mineralization at depth.
