Oct 23, 2019 (Sheree Hinz) - This property is located along the Montreal River Fault, which is part of a major fault set related to the development of the Lake Superior Basin and the Kapuskasing Structural Zone. Radioactive occurrences are known to be associated with this fracture system in the Montreal River Harbour area

Oct 23, 2019 (Sheree Hinz) - The radioactive zone appears to occur along a shear zone, that trends east and dips vertically. The shear zone is part of the Montreal River Fault. The fault zone is approximately 2000m in length along the north bank of the Montreal River and is approximately 25 m in width. The zone is composed of intensely brecciates, fractured, carbonatized, and silicified mafic to intermediate metavolcanics. The presence of the radioactive materials is probably due to the development of the fault.

Oct 23, 2019 (Sheree Hinz) - Two samples were submitted by Gimby for assay in 1952; one from a pegmatite which gave 0.063 percent U308 and one from a biotite gneiss which gave 0.081 percent U3O8. A grab sample was taken by E.C. Grunsky in 1981 from a biotite gneiss at the west end of the Montreal River Fault on the northern bank of the Montreal River, and was submitted for assay to the Geoscience Laboratories of the Ontario Geological Survey. A value of 0.026 percent U3O8 was reported for this sample.
