History

Exploration in the area dates back to the 1940's. In 1947, gold was discovered in four zones that extend over 400 m along a west-northwest striking shear zone. The discovery generated a wave of exploration work that included stripping, trenching, and diamond drilling of 449 m (1473 feet) in 22 holes to test the No. 1 Zone. The zone was tested to 30 m (100 feet) vertical depth with intercepts up to 35.3 g/t gold across 3.2 m (1.03 oz/ton across 10.7 feet).

In 1953 Greenoaks Mines Ltd completed electrical resistivity, ground magnetometer, and geological surveys and drilled 509m (1670 feet) in three holes to test newly located geophysical anomalies separate from the gold zones. This drilling did not intersect significant veining or gold mineralization.

Five holes totaling 302 m (991 feet) were drilled on the No 1 Zone in 1960. These holes confirmed the presence of veining and gold mineralization to 30 m vertical depth and included intercepts carrying up to 13.0 g/t gold across 1.06 m (0.38 oz/ton across 3.5 feet).

In 1982, 1,224 tons of ore was mined and of this, 1,171 tons were milled at the Pan-Empire Mill in Beardmore returning an average grade of 0.18 oz/ton (6.1 g/t) gold. Northern Concentrators milled the remaining 53 tons in Thunder Bay and returned an average grade of 0.50 oz/ton (17.1 g/t) gold.

In 1983, Turner Energy Resources Ltd reported results in a press release from six holes, 315 m (1033 feet) completed on the No 1 Zone. The drill intersections range from 2.7 g/t across 0.42 m (0.08 oz/ton across 1.4 feet) to 74.7 g/t across 0.76 m (2.18 oz/ton across 2.5 feet). The exact locations and details of these holes have not been found.

Alto Ventures acquired the property in 2004 and completed 5 diamond drill holes totaling 331 m in 2007. Two of the holes intersected visible gold with assays including 12.5 g/t gold across 0.4 m and 7.08 g/t gold across 0.8 m. Hole GRN07-05 is the deepest test of Zone 1, intersecting the zone at 50 m vertical depth. This hole cut 1.2 m of solid quartz vein containing 5% sulphides including pyrrhotite and chalcopyrite. The gold assays only 0.11 g/t but the intersection is very encouraging as it indicates that the vein system continues to depth. Additional drilling is required to further evaluate this property.

2008 Exploration Programs

Planned work for the 2008 summer includes prospecting, mechanical trenching and sampling. This will be followed by diamond drilling.
