The area, according to Muller, is underlain by a Metagreywacke- Schist Unit and an Argillite-Metagreywacke Unit, both of the Jurassic to Cretaceous Leech River Complex (Geological Survey of Canada Open File 821). The former unit consists of metagreywacke, meta-arkose and quartz-feldspar biotite schist; the latter consists of thinly bedded greywacke and argillite, slate, phyllite and quartz-biotite schist

A gold nugget was reported to have been found, in 1893, in a small stream flowing into Providence Cove. Further prospecting led to the discovery of several quartz veins, all carrying small quantities of gold on the surface outcrops (Minister of Mines Annual Report 1893, page 1079). A sketch map, accompanying the Annual Report, shows the location of two claim groups which apparently cover the showings. One of the veins strikes 060 and dips 45 degrees to the north and occurs in "micaceous slates and granites".
