The Kali property is located at the Western end of the Eastmain Greenstone Belt. It consists in a magmatic porphyric/mantos (Cu, Au, Ag, Mo) mineralization, similar to these of Eau Claire (33B04) and Opinaca (33C01, 33C02 and 33C08). The Cu-Ag-Au mineralization of Lake Kali is hosted within crystal felsic tuf of Wabamisk formation near the SE edge of the Kali pluton. This intrusion is generally porphyric (blue quartz and plagioclase) and of similar age (2 701 Ma) with Wabamisk Formation (2 690 – 2 712 Ma: Moukhsil et al. 2001). Mineralization consists of decimetric to metric bodies and regular structures of pyrite-chalcopyrite-malachite disseminated within the altered (silicified and argillic) host lithologies. The mineralized structures are oriented ENE-WSW and WNW-ESE and are pre- to syn tectonic.

Line cutting and a MAG-TBF survey have been done on the Kali property in 1995 and 1996. Further to mapping and geochemistry work done in 1997, an important polymetallic deposit was discovered. Grab samples results gave : 35 000 ppm and 33 000 ppm in copper; 1 376 ppb and 684 ppb in gold; and, 41,4 ppm and 29,4 ppm in silver (A.Belkabir, Ph.D. 1998)

Sampling, soil geochemistry, geophysics have been made in July 2006. Numerous samples coming from pedogeochemical surveys and lithogeochemical surveys were assayed by ALS CHEMEX of Val d’Or (Quebec). Furthermore, in order to delineate new sulphide targets, a VTEM airborne geophysical survey totalizing 914 line kilometres was performed by Geotech Ltd of Aurora (Ontario), over the Kali property in November 2006. Reports and maps were produced in February 2007, and are under study. Diamond drilling will follow on priority targets.
