The Greywacke deposit (Greywacke North) is located approximately 90 km northeast of La Ronge, Saskatchewan within the Proterozoic McLean Lake Belt. This group of rocks includes arkoses of the McLennan Group, the McLean Lake quartzo-feldspathic gneisses, amphibolitic calc silicate units and locally pegmatitic granite.

The deposit and other related gold occurrences occur in a sillimanite bearing quartzo-feldspathic sedimentary package referred to as the Wacke trend/horizon. They were discovered by Cameco Corporation between 1987 and 1988, who were following up gold in lake sediment anomalies.

Previous Work

From 1989 to 1991, 36 diamond drill holes tested a 6 km strike length of the Wacke trend. Half of these targeted the Greywacke North zone, where a possible reserve of 328,000 tons @ 0.27 oz/ton Au has been outlined (Cameco-1991 winter report). This mineralization is still open along strike and down plunge. The deepest intercept was in hole #30 which returned 0.209 oz/ton Au/2.0 m at a vertical depth of 225 m; while the broadest\intercept was in hole #13 which returned 0.151 oz/ton Au/21.0 m at a vertical depth of 75 m. Encouraging results were also obtained from the Greywacke South Zone, with the best result being 0.155 oz/ ton Au/4.5 m from hole #7, which tested the zone at 50 m vertical.

In 1992 Cameco's exploration philosophy changed with more focus and funds being directed to the international scene, at the expense of the local scene. In 1994, four additional holes were drilled, three on Greywacke South and one on Greywacke North. All targeted the mineralized zones at approximately 200 m below the surface. Significant, albeit narrow intervals of gold mineralization were returned from broad sulphidic zones that were intersected in all four drill holes; clearly indicating that the mineralization is open at depth. No further exploration activities have been carried out since then.

The company Shane Resources acquired a 50% interest in this property in April of 2001, along with JNR Resources (50%). Subsequently, Masuparia Gold Corporation agreed to fund exploration on the property in order to earn up to a 70% interest by spending $2,850,000.

The objective on Greywacke is to prove up a mineable orebody containing at least 300,000 ounces of gold. Previous drilling outlined a rough calculation of about 100,000 ounces contained in 328,000 tons (0.27 ounces per ton). Masuparia has to date spent about $850,000, thus earning their first 50% of the property. In order to earn the next 20%, Masuparia must spend a further $2,000,000. Results from the three drill programs conducted to date by Masuparia outline the potential for a mineable deposit.
