Diamonds North Resources acquired 100% interest in the Esker gold property in Nunavut. The Esker claim covers several kilometres of gold bearing stratigraphy. Drill intercepts of gold mineralization are as high as 8.2 g/T gold over 13 metres, including 17.7 g/T gold over 5.7 metres; and, 2.4 g/T gold over 71 metres which includes several high grade zones (see table below). For a video presentation on this project visit our website www.diamondsnorth.com. "This low cost staking puts us into a project with wide zones of high grade gold mineralization and significant tonnage potential. As only a small portion of the zone has been tested, our objective is to drill along strike of the known mineralization along the host gabbro units to expand the gold-bearing mineralized zone," says Mark Kolebaba President and CEO of Diamonds North.
