The Sognidoro showing is located approximately 27 kilometres northwest of Chemainus, south of Rheinhart Lake. A 100 metre adit occurs on the nearby Trek claims possibly from as early as 1918.

The area is underlain by metasedimentary rocks of the Mississippian to Pennsylvannian 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.

Mineralization comprises pyrite, chalcopyrite, galena, bornite, molybdenite, azurite, malachite and chalcanthite hosted within quartz veins. Pyrite, chalcopyrite, hematite and magnetite also occur within jasper horizons. Galena was observed in a quartz vein cutting a diabasic outcrop within the southerly flowing creek on the western side of the claim. Base and precious metal values are locally associated with this mineralization.

The main vein is the McDougall vein, striking 320 degrees and dipping 70 degrees east, which has been traced for 265 metres. Mineralization apparently increases in quantity toward the northern end of the vein. The vein is hosted in, and conformable with, chloritic schists. The McDougall vein may be truncated by faults at both ends with a suggested right-lateral displacement of 200 metres at the northern extent. A sample, from a pit on the vein, containing iron oxides, malachite, chalcanthite and up to 2 per cent chalcopyrite, assayed 0.58 gram per tonne gold, 3.7 grams per tonne silver, and 0.28 per cent copper (Assessment Report 16802).

Two jasper showings are located approximately 300 metres north of the McDougall vein. These are also hosted in and conformable with the chloritic schists. The horizons are exposed over 30 and 25 metre widths and along strike for 200 metres and 50 metres respectively. The jasper appears to occur in lenses but it could be part of a continuous horizon displaced by right-lateral faulting. The jasper, brick to scarlet red with metallic grey patches, is cut by numerous quartz veinlets (up to 0.5 centimetre). Iron oxides and malachite staining occurs locally. Pyrite and chalcopyrite occur primarily in the veinlets. Finely disseminated and massive magnetite occurs within the jasper "lenses". A sample of jasper cut by quartz veinlets containing pyrite and magnetite assayed 0.72 gram per tonne gold, 0.5 gram per tonne silver, 0.0418 per cent copper and 41.69 per cent magnetite (Assessment Report 16802). In 2011, selected grab samples of hosting chalcopyrite and bornite from the quart-jasper-sulphide showings assayed up to 9.35 per cent copper and 28.9 grams per tonne silver (Assessment Report 32850).

In 1988, Trek Resources Ltd. completed a twenty four hole percussion drilling program, totalling 388.0 metres. During 2009 through 2011, Rock-Con Exploration completed programs of spectral analysis, prospecting and rock and soil sampling on the Sognidoro property.

Geochemical and geophysical surveys have been done on the nearby Imp and Imperial claims. The results of these programs were discouraging and no mineralization was found.
