The Debbie 3 occurrence is underlain by porphyritic mafic volcanic rocks of the Devonian Nitinat and Duck Lake formations of the Sicker Group. These include massive and pillowed basalts and volcaniclastics. The volcanic sequence is crudely stratified, strikes north-northwest and dips moderately east and contains narrow to broad zones of schistosity conformable with stratification. Chlorite schist represents the metamorphosed and deformed mafic rock.

A north trending, 200 metre wide, pyritic sericite-chlorite- carbonate schist zone occurs in the area. A drill hole, cutting the alteration zone, assayed 2.06 per cent zinc, 0.32 per cent copper, 0.04 per cent lead and 5.8 grams per tonne silver over 0.6 metres (Assessment Report 15287). Mineralization intersected in the drill hole includes thin bands and disseminations of pyrite and minor gypsum, sphalerite and chalcopyrite. The drill hole also inter- sected a 1.3 metre width of disseminated and massive stibnite (9.40 per cent over 7 centimetres). This alteration zone appears coincident with a fault (Geological Survey of Canada Open File 1272).

Three hundred and fifty metres south of the drill hole and 350 metres east of the alteration zone is a surface showing of banded, fine-grained sphalerite with minor chalcopyrite and galena in four lenses, 4 to 20 centimetres thick, conformable within schistose porphyritic basalt clastics. Schistosity strikes 160 degrees and dips 49 degrees east, with lineation plunging 14 degrees south- southeast. A 20 centimetre sample assayed 14.1 per cent zinc, 0.87 per cent lead and 0.12 per cent copper (Assessment Report 13758).
