The Titrite showing is located east of the Illiance River, about 16.5 kilometres northeast of Alice Arm. Various showings in this area have been explored for gold, silver and copper since 1918.

The region is underlain by Lower Jurassic Hazelton Group volcanics and sediments situated on the east limb of the north-northwest trending Mount McGuire anticline. These rocks have been regionally metamorphosed to greenschist facies.

The showing comprises various occurrences hosted in interbedded calcareous tuff and breccia. The occurrences consist of quartz, quartz-calcite and barite veins varying from 0.20 to 1.8 metres wide. The veins contain variable amounts of sphalerite and galena with minor chalcopyrite, arsenopyrite and/or argentite. A 0.61 metre wide quartz vein strikes 168 degrees and dips 70 degrees northeast, and a 0.30 metre wide quartz-calcite vein strikes 098 degrees and dips 60 degrees south. A sample of a 0.20 metre wide quartz vein with chalcopyrite and trace argentite assayed trace gold, 206 grams per tonne silver and 0.6 per cent copper (Minister of Mines Annual Report 1918, page 73). A sample of a brecciated quartz vein with sparse pyrite and galena, assayed trace gold and 54.9 grams per tonne silver (Minister of Mines Annual Report 1931, page 39).

Several showings occur in a shear zone containing quartz and calcite stringers mineralized with pyrite and sphalerite. A 1.8 metre wide pyritized and silicified breccia zone containing minor chalcopyrite is reported to lie among the various vein showings.
