The Dickson occurrence is located on western side of the Little Nitinat River, approximately 3.7 kilometres south east of Francis Lake.
The area is underlain by granodioritic intrusive rocks of the Early to Middle Jurassic Island Plutonic Suite.
Locally, several small mineralized quartz veinlets are hosted in granodiorite. A short crosscut adit (8.5 metres) had been driven to intersect two veins mineralized with pyrite and minor galena. The veins range up to 15 centimetres in width. A grab sample from one vein assayed 47.99 grams per tonne silver (Minister of Mines Annual Report 1916, page K313).
Two more parallel quartz veinlets occur 122 metres north of the adit in the bed of the Little Nitinat River.
