The Scotch occurrence area is underlain by a tightly folded and overturned? sequence of metavolcanic and metasedimentary rocks of the Devonian Skwaam Bay unit and Devonian and/or older? Woolford Creek unit, both of the Eagle Bay assemblage. The rocks exhibit a well developed foliation generally striking west and dipping between 25 and 30 degrees north.
Diamond drilling has intersected a stratigraphic sequence comprised of sericite chlorite phyllite, graphitic argillite, interbanded argillaceous marble and calcareous argillite, chlorite sericite schist, quartz sericite schist and calcareous argillaceous siltstone.
Stratabound and stratiform dispersed and massive sulphide mineralization has been discovered in several places on and near the property, as well as in drillholes. The predominant sulphide mineral is pyrrhotite, with lesser pyrite and variable amounts of sphalerite, galena and chalcopyrite.
A drillhole located 2000 metres west of the main mineralized area intersected minor interbands and stringers of pyrrhotite, pyrite, chalcopyrite, sphalerite and galena.
