The Solly North occurrence is located from approximately 720 to 820 metres elevation on a southwest-facing slope, northeast of Solly Creek and approximately 3.9 kilometres south-southwest of Mount Hall. The Lara (MINFILE 092B 192) developed prosect is located approximately 700 metres to the southwest.

Regionally, the area is underlain by chert, siliceous argillite and siliciclastic rocks of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group) and volcanic rocks of the Middel to Upper Devonian McLaughlin Ridge Formation (Sicker Group), which have been intruded by gabbroic bodies (called the Mount Hall Gabbro) that are coeval with the Upper Triassic Karmutsen Formation (Vancouver Group). See the Lara (MINFILE 092B 129) occurrence for a larger discussion of the regional geology.

Locally, a moderately spaced grouping of drillholes has identified weak to moderate polymetallic mineralization similar to that of the nearby Randy North (MINFILE 092B 128) and Lara (MINFILE 092B 129) occurrences.

In 1987, diamond drilling yielded intercepts including 0.240 per cent copper, 0.100 per cent lead and 0.525 per cent zinc over 1.54 metres (67.44 to 68.98 metres down hole) from a quartz eye tuff and cherty tuff hosting quartz veins and veinlets with sphalerite and chalcopyrite in hole 87-177; 0.400 per cent copper over 0.32 and 1.57 metres, each, (542.88 to 543.40 and 577.52 to 579.08 metres down hole, respectively) from a volcaniclastic sequence with crystal lithic tuff hosting disseminations and stringers of chalcopyrite, pyrite and pyrrhotite in hole 87-210; 0.076 per cent copper, 0.240 per cent lead, 0.480 per cent zinc, 3.0 grams per tonne silver and 0.380 gram per tonne gold over 0.31 metre (60.96 to 61.27 metres down hole) from a quartz eye crystal tuff hosting quartz veins with pyrite, sphalerite and chalcopyrite in hole 87-211; 0.550 per cent copper over 1.22 metres (104.87 to 106.09 metres down hole) from an andesite lapilli tuff hosting veinlets and blebs of pyrite and chalcopyrite in hole 87-213; 1.066 per cent zinc over 1.55 metres (21.81 to 23.36 metres down hole) from a lithic tuff hosting sphalerite in hole 87-214; 0.131 per cent copper, 0.257 per cent lead, 0.674 per cent zinc, 3.7 grams per tonne silver and 0.222 gram per tonne gold over 0.70 metre (217.86 to 218.56 metres down hole) from a rhyolite quartz eye tuff hosting pyrite with minor chalcopyrite, sphalerite and trace galena and tetrahedrite and 0.640 gram per tonne gold over the following 1.60 metres (218.56 to 220.16 metres down hole) from a rhyolite dust tuff hosting pyrite blebs with trace chalcopyrite in hole 87-216 (Assessment Report 17857).
