The Lefty showing area is underlain andesite and lesser rhyolite of the Lower Jurassic Telkwa Formation, Hazelton Group.

The Lefty showing is a 3 by 0.6 kilometre epithermal system outlined with values up to 4.1 grams per tonne gold across 0.6 metre. Mineralization occurs as 020 to 060 degree trending quartz veins, stockwork and breccia zones with minor pyrite, chalcopyrite and sphalerite, locally with more massive pyrite and chalcopyrite zones (Assessment Report 20741).

In 2008, more significant results were obtained from the Lefty, 1.5 kilometres to the west, which is located to the east of the property and primarily within Burnie-Shea Park. Quartz veins, stockwork and breccia zones with minor pyrite, chalcopyrite and sphalerite, locally with more massive pyrite and chalcopyrite zones, are exposed over a 3 by 0.6 kilometre area. Maximum values obtained were 0.69 per cent copper, 4.96 grams per tonne gold across 1.5 metres from the hanging wall of a quartz stockwork breccia zone which returned 0.21 per cent copper, 2.09 grams per tonne gold with 0.15 per cent zinc across 1.5 metres (Assessment Report 31515).
