The Sonya-Hectoria occurrence is located on the east side of the Stellako River, approximately 3 kilometres northeast of the river’s outlet from Francois Lake.

The area is underlain mainly by granodiorite of the Francois Lake Intrusive Suite and volcanic rocks that are probably correlative with the Cretaceous to Neogene Ootsa Lake Group.

Locally, several approximately parallel, narrow fractures (a few centimetres wide) occur entirely within the granodiorite or at the contact with volcanic rocks. Mineralization consisting of sphalerite, pyrite and a little chalcopyrite occurs in the fractures. Assays indicated only traces of gold and silver.
