Feb 24, 2020 (Therese Pettigrew) - The main lithology is red Sibley mudstones and sandstones. Several small diabase dykes parallel a major fault or shear structure that strikes N80E (Thunder Bay Mineral Deposit files).

Feb 24, 2020 (Therese Pettigrew) - The mineralization appears to relate to the contact between the sandstones and diabase and parallels the fault on the south side. The major zone comprises a calcite-barite vein carrying copper and lead mineralization over widths from 2 inches to 4 feet and a surface length of about 100 feet. This strikes N80E and appears to dip vertically. The mineralization is in the form of galena cubes and crystals, usually massive, in a calcite and barite gangue. The copper mineralization is in the form of chalcopyrite, with a little malachite, occurring with quartz in fissures alongside or between the barite and calcite. These veins cut the Sibley mudstones conformably with the faulting system, and diabase dyklets with which they are associated, at a steep dip and strike roughly N80E. Samples returned 4.62% Pb, 15.30% Pb, 20.49% Pb, and 57.21% Pb, as well as 0.42 oz/t Ag, 2.05% Cu, and 2.58% Zn (report in Thunder Bay Mineral Deposit files).
