The Florentia occurrence is located on the east fork of the Robertson River, approximately 10 kilometres south-southwest of the community of Cowichan Lake.

The area is underlain by Lower Jurassic Bonanza Group volcanics consisting of lava, tuff and breccia of mainly basaltic to rhyolitic composition. It contains occasional interbeds and sequences of marine argillite and greywacke. A stock of the Early to Middle Jurassic Island Plutonic Suite (formerly called the Island Intrusions) lies to the southwest of the showings. The volcanics have been intruded by dykes and irregularly shaped bodies of granodiorite, granite porphyry and diorite porphyry. Limestone, reported to occur as lenses and roof pendants in both the volcanics and the intrusive, is probably related to the Quatsino Formation, (Vancouver Group).

Locally, sulphide mineralization of pyrite and possible sphalerite occurs near the contact of limestone and basalts. In 2006, a sample of mineralized material assayed greater than 1.0 per cent zinc (Assessment Report 34256).

The area has been historically explored in conjunction with the nearby ALPHA-BETA (MINFILE 092C 039) occurrence. In 2013, the area was prospected as the Florentia claim.
