The Overlander North occurrence is located at an elevation of approximately 1500 metres on an east trending ridge separating May and Skeff creeks.
The area is underlain by volcanics and metasediments of the Carboniferous to Permian Attwood Group, ultramafic rocks of the Carboniferous to Permian Mount Roberts Formation(?), greenstones of the Devonian to Permian Knob Hill Group and undivided sedimentary rocks of the Triassic Brooklyn Formation which have been intruded by dioritic rocks of the Middle Jurassic Providence Lake Complex, granodioritic rocks of the Cretaceous Anstey Pluton and syenitic to monzonitic rocks of the Eocene Coryell Plutonic Suite.
Locally, a historic trench exposes a silicified limestone hosting numerous epithermal quartz veins and rusty (oxidized) pods with no visible sulphides.
Another zone of mineralization, located approximately 300 metres to the north east, comprises a silica altered limestone hosting pyrite, chalcopyrite and malachite along calcite veins near an intrusive contact.
During 2008 through 2012, Grizzly Discoveries Inc. completed programs of soil, stream sediment and rock sampling, geological mapping, and ground geophysical surveys on the area as the Overlander area of the Greenwood property.
In 2011, a sample (11CGP020) from a historic trench assayed 37.90 grams per tonne gold and 1.7 grams per tonne silver, while three samples (11JPP021, 11RGP038 and 11RGP039) from the north east zone yielded values of up to 0.334 gram per tonne gold, 31.5 grams per tonne silver, 4.69 per cent copper and 0.319 per cent zinc (Dufresne, M.
