Dec 07, 2005 (B Schnieders) - The occurrence is located on the NE extension of the Dorion Mine Fault Zone. On surface the mineralized zone has been traced for 405 feet over widths ranging from 3 to 30 feet. The vein consists of quartz, calcite and barite irregularily mineralized with galena, sphalerite and rare chalcopyrite (Shlaanka, 1969 MRC #12). Biotote granite lies 50 feet northwest of the shaft, and in the sediments on the south are two bands of breccia which show minor displacements in the sediments themselves, grey cherty dolomite being downfaulted against brown sandstone (ODM, Vol 38, Part 6, 1929).
