The Blackburn is located northwest of Kaslo Lake, in Kokanee Glacier Provincial Park.

A mineralized shear zone in coarse-grained Nelson granite. Vein quartz occurs in small irregular lenses and stringers carrying a sparse dissemination of sulphides. The lode strikes north 65 degrees west and dips steeply southwest. The hangingwall is partly defined by a narrow fine-grained basic dyke.

Two ore types: 1) sphalerite-rich with pyrite and quartz vein, 2) galena-rich carbonate vein with characteristic manganese oxide weathering.

The veins occur in fresh potassium feldspar porphyritic granite, sub-parallel to prominent northwest trending linears. A sample taken in 1987, assayed 510 grams per tonne silver, 0.155 grams per tonne gold, 0.067 per cent copper, 1.1 per cent lead and 12.1 per cent zinc (Open File 1988-11).
