The Tonga property has significant potential for hosting silver, gold and zinc mineralization and other portions are also molybdenum anomalous. Previous soil, silt and talus fine geochem sampling in the center of the property indicated highly anomalous levels in all of these elements. Drilling in 2006, targeting coincident geochemical and geophysical airborne anomalies, intersected low-grade zinc-silver mineralization but did not explain the molybdenum geochemistry. It is now believed that the geochemical anomaly may be transported, suggesting that the source lies south at higher elevations.
The Tonga property is located 32 kilometres southeast of Stewart, British Columbia, at the headwaters of the O’Neill River and adjoining the Fiji property to the south. Silver Grail Resources Ltd. and Teuton Resources Corp. own the property jointly (50-50).
