A lead zinc occurrence. The occurrence consists of a system of mineralized calcite and quartz veins with the following dimensions: 0.5 to 4.0 feet wide, 930 feet long, 3 feet wide 200 feet long, and 330 feet long. Workings consist of 3 shallow trenches and at least 5 pits.

Geology:
mineralized veins occur near the boundary of thick, folded sequences of marbles and clastic siliceous metasedimentary rocks. These rock sequences are bounded to the north by the Tudor Gabbro and to the east by the Tudor volcanics and the Lingham Lake mafic intrusive complex. The resultant bedding features in the area are oriented north to northeast and are steeply dipping or vertical.
In places, particularly in the central parts, the calcite veins, which are drusy and contain angular inclusions of the country rocks, show carb structures with either a central cavity containing crystals of calcite,
quartz, barite and sulphide minerals, or a central zone of interlocking calcite crystals... In appropriate order of relative abundance, minerals present in the calcite veins are: calcite, barite, galena, quartz, pyrite, sphalerite, and rarely, pale green fluorite. Most of these minerals
are found as subhedral to euhedral, coarse-grained crystals and crystal aggregates, but some massive pockets of galena are present locally.

The occurrence is located in the southeast part of Tudor Township, approximately 1.0 kilometre southeast of Millbridge and 5.0 kilometres north of Bannockburn. It is accessible on foot a short distance west of Highway 62 at a point about 1.0 kilometre north of the junction with the south access road to Millbridge. The occurrence is indicated on ODM map 2168
(Lumbers 1969).
