Exploration History
The Mosher Lake Property covers the Gold Island Showing where gold mineralization is hosted by sheared Precambrian meta-sedimentary rocks of the Yellowknife Supergroup. The showing was discovered and trenched in 1938. Huhill Yellowknife Mines completed 40 small diameter holes (total: 4,274m) in 1946-47. Twenty-seven holes intersected the mineralization shear zone and visible gold was observed in 14 of the holes. Numerous multi-ounce gold assays were returned, but the analytical data were compromised by incomplete sampling, small samples and a strong nugget effect. Many samples with visible gold did not report high assay values. At that time, "professional sampIing" dictated that the visible gold was to be removed from the sample prior to assaying. Generally only the quartz veins were sampled and many thick sulfide - rich stockwork zones were not sampled.

Three larger diameter holes were drilled in 1974 by Seaforth Mines. These holes revealed the potential for significant mineralization within a 35 to 40 metre thick zone grading more than 2.5 g/t gold. Higher grade sections of up to 6.4 g/t gold over 10 meters occur within the broad mineralized zone. Sampling was again incomplete and a strong nugget effect was still evident. As an example, Seaforth's drill hole 74-2 encountered 5 occurrences of visible gold but no high grade assay results were obtained. This program showed, however, that the gold was not restricted to the quartz veins but was distributed throughout the mineralized shear zone.

In 1990, metallurgical tests of previously trenched material indicated the head assays from bulk leach analyses were 20% higher that the fire assayed feed samples. In 1990, an airborne EM and magnetic survey outlined 5 significant EM anomalies, some with coincident magnetic signatures; but no follow-up work was done. One very large magnetic anomaly was delineated over the Gold Island Showing and extends 500 meters to the south.

In 1996 an extensive program of ground geophysics (EM VLF, magnetics and IP) was done by Firesteel over the northern part of the property. Anomalies were defined over Gold Island and drill targets were identified. Another cluster of very strong anomalies was defined to the northwest. These are likely related to the faulted extension of the belt. The targets here are related to volcanic rocks and there is no record of previous work in the area.

The known mineralization at Gold Island occurs within sheared, altered and mineralized meta-sediments in a geological setting similar to the prolific, high grade Discovery Mine. Previous attempts at exploration and gold grade estimation have been plagued by inadequate sampling and uncertain assay results - partly due to the nugget effect of coarse gold. The prior drilling tested the zone over a strike length of 240 meters and to a depth of 125 meters. The zone is open along strike and can be traced by geophysics for at least 500 meters further to the south.
