The Sognidora Gossan occurrence is located east of Rheinhart Creek, approximately 400 metres south of Rheinhart Lake. The showing has been explored in conjunction with the Sognidoro (MINFILE 092C 144) occurrence since its discovery in 1987 by Canamin Resources.

The area is underlain by metasedimentary rocks of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Group) and volcanic rocks of the Upper Devonian McLaughlin Ridge Formation (Sicker Group). These two formations were historically referred to as the Myra Formation and contained the ‘Sediment-Sill unit’ of the Sicker Group. The Sediment-Sill unit has been tentatively correlated with the Fourth Lake Formation and the ‘sills’ have been mapped separately. The sills are believed to be coeval with the Karmutsen Formation basalts and are informally named Mount Hall gabbro. These rocks have been intruded by granitic rocks of the Early to Middle Jurassic Island Plutonic Suite.

Locally, a gossanous, altered felsic intrusive with hematite, disseminated pyrite and iron oxide staining hosts copper mineralization. In 1987, a sample (17839) returned 538 parts per million copper (Assessment Report 16802).

From 2009 through 2011, Rock-Con Exploration completed programs of spectral analysis, prospecting and rock and soil sampling on the Sognidoro property.
