The All The Marbles 1 occurrence is located on a ridge separating Lens and Harris creeks, approximately 2 kilometres north east of Lizard Lake.

The area is underlain by diorite and quartz diorite of the Paleozoic to Jurassic Westcoast Crystalline Complex . Seams, 2 to 5 metres wide, of dark green to black serpentinite cut the diorites.

Locally, quartz veins in diorites and serpenitinite host chalcopyrite and pyrite mineralization.

In 2005 through 2010, Le Baron Prospecting completed programs of geochemical sampling and prospecting on the area as the All The Marbles 1-2 claims. In 2008, two samples (H031238 and H031243) of pyritic sulphides assayed 24.3 and 45.5 grams per tonne silver, respectively, greater than 1 per cent copper and greater than 1 per cent zinc. A sample (H031240) of serpentinite, from the same area as the sulphide samples, assayed greater than 100 grams per tonne silver and greater than 1 per cent copper, zinc and lead (Assessment Report 30512).
