02/24/2020 (T Pettigrew) - The area is underlain by Sibley formation sediments, mostly dolomites and cherty dolomites. These sediments are flat lying or gently dipping, and covered by 1 to 5 feet of overburden. A flat-lying diabase sill borders the claim group to the south. A narrow dyke of fine-grained diabase was observed in the trenches on the showing No. 1. The dyke appears to strike 0.050 degrees and dip steeply (85 degrees) to the east. A zone of brecciation accompanied this dyke. Vertical veis of calcite, batite and sulphides, usually galena with some sphalerite and chalcopyrite cut the horizontal dolomites. Some of the veins are exposed in showings No. 1, 2, and 3, on claim TB 110416. The veins as exposed by trenching show variable widths from 0.1 to 3.0 feet. Strike of the mineralized veins varies from 025 to 060 degrees (Central & Eastern Canada Mines prospectus report in Thunder Bay assessment files).

02/24/2020 (T Pettigrew) - The mineralized veins appear to be associated with the diabase sill and appear to be controlled by fracturing or jointing in the dolomites. Vein widths vary from 0.1 to 3.0 feet. Massive galena in stringers and segregations occurs at random within the vein material. The chief gangue mineral is barite, with some minor quartz and calcite. The length of the veins has not been determined due to overburden and incomplete trenching, however showing No. 2 give a length of approximately 40 feet of exposed vein. Sampling of the vein in Showing No. 2 returned up to 10.15% Pb and 0.06 oz/t Ag over 2.2 feet. Drill sludge from Showing No. 1 returned 27.22% Pb, 1.51% Zn, and 0.08 oz/t Ag over 5 feet. Massive galena picked from showings 1 & 2 returned 82.90% Pb and 0.10 oz/t Ag (Central & Eastern Canada Mines prospectus report in Thunder Bay assessment files).
