The Tas South occurrences are located in the south western head waters of Wolfe Creek, at an elevation of approximately 1400 metres.

The area is underlain by the eastern facies of the Upper Triassic Nicola Group consisting of mafic augite and hornblende porphyritic pyroclastics and flows. These have been intruded by dioritic rocks of the Late Triassic to Early Jurassic Copper Mountain Stock.

Locally, two occurrences, the Cliff and Road, have been identified and consist of zones of propylitic, potassic and epidote altered monzonite of the Copper Mountain intrusions hosting varying concentrations of chalcopyrite as disseminations and along fractures or veinlets.

In 2009, chip sampling yielded an average of 0.324 per cent copper over 10 metres from north to south and 0.203 per cent copper over 7 metres from east to west. Select grab samples yielded up to 1.28 per cent copper and 7.6 grams per tonne silver (Assessment Report 31363).

In 2010, chip sampling on the Cliff occurrence yielded values of 0.25 per cent copper and 2.2 grams per tonne silver over 8.5 metres from trench T-9 cut-2, while trench T-9 cut-4 yielded an average of 0.28 per cent copper and 3.9 grams per tonne silver over 8.3 metres. The same year, a diamond drill hole (21004) intercepted 19 metres averaging 0.20 per cent copper and 2.7 grams per tonne silver (Assessment Report 33062).

In 2010, a diamond drill hole (21007) on the Road occurrence yielded an average of 0.19 per cent copper and 1.5 grams per tonne silver over 17 metres. Another drill hole (21112) yielded an average of 0.16 per cent copper over 15.3 metres, including 3.1 metres averaging 0.45 per cent copper (Assessment Report 33062).

In 1972, Phelps Dodge completed a program of geological mapping, soil sampling and ground magnetometer and induced polarization surveys on the area as the Tas and Tat claims. During 1991 through 1994, G.F. Crooker completed programs of silt sampling, geological mapping and ground geophysical surveys on the area as the Tas 1-2 claims. In 1996, Moreleigh Minerals completed a program of geological mapping, soil and rock sampling and ground electromagnetic and magnetic surveys. In 2009 through 2011, Supreme Resources completed programs of geochemical sampling, a 19.5 kilometre induced polarization survey and five diamond drill holes, totalling 1485.5 metres, on the area.
