The D showing occurs south of Chuchi Lake near its western end. This area is underlain by the southeastern end of the Late Triassic to Early Cretaceous Hogem Intrusive Complex, here consisting of an Early Jurassic monzonite phase. The monzonite is in contact with volcanic and sedimentary rocks of the Upper Triassic Inzana Lake Formation, Takla Group (Open File 1992-4).

Andesite-basalt plus coarser gabbro-pyroxenite comprise the rocks immediately south of the west-trending intrusive contact. No mineralization was observed in the monzonite but the rocks south of the contact are pyritic and contain traces of chalcopyrite (Assessment Report 3851, page 6).

An iron showing occurs about 2 kilometres to the east-northeast of these copper showings, just southwest of the mouth of Jean Marie Creek in Chuchi Lake (Geological Survey of Canada Preliminary Map 45-9, Paper 45-9). No other information is available on this iron showing.

Work History

The Tan group was staked in 1966, 2 kilometres to the southeast of the D showing and centred on Jean Marie Creek.

In 1967, geophysical and geochemical surveys indicated at least two anomalous areas on the property; one of these coinciding with several high soil samples of up to 450 parts per million copper. Soil samples taken on the property ran as high as 720 parts per million copper and the one silt sample taken returned 190 parts per million copper (Property File Cyprus Anvil H. Veerman, 1967). Pyrite, chalcopyrite and bornite were found in two outcrops on the Tan claims. West of the claims, magnetite as a basic constituent and in veinlets or masses was also found.

In 1971, Boronda Exploration Corporation Limited completed a geophysical and geochemical program on the property containing the occurrence. The geophysical survey found two anomalous zones.

From 1990 to 1992, Westmin Resources Limited completed an exploration program on the area of the occurrence including various geochemical and geophysical surveys. Anomalous zones of copper and gold were identified.

In 2005, Serengeti Resources Inc. conducted geochemical and geophysical surveys on the property containing the occurrence. The results showed a copper soil anomaly and an induced polarization anomaly surrounding the occurrence.

In 2006, Serengeti Resources Inc. conducted an exploration program on the property containing the occurrence. No quantitative results were mentioned at the occurrence.

In 2011, Serengeti Resources Inc. conducted an exploration program including line cutting, induced polarization surveying and Ah soil sampling. An aeromagnetic high anomaly, induced polarization chargeability anomaly and copper-in-soil anomaly was observed in the area surrounding the occurrence.
