Dec 07, 2005 (B Nelson) - Carter (1981c) reported that an assay of 0.02 oz/ton Au was obtained from a rusty shear zone, from a fault near Von Lake. The north-northeasterly trending fault separates fine-grained mafic metavolcanics on the west from fine-grained variolitic, intermediate metavolcanics on the east.

Dec 07, 2005 (B Nelson) - An assay of 0.02 oz/ton Au was obtained from a rusty shear zone (Carter, 1981c).
Jun 29, 2018 (Therese Pettigrew) - Fine-grained disseminated mineralization was observed in a rusty, limonitic shear zone 1.8 m wide and 18 m long, striking N 60 E. The shear zone is in a fault juxtaposing mafic and intermediate metavolcanic rocks in an area underlain predominantly by mafic metavolcanic rocks. A grab sample of the material collected during the 1981 survey and assayed by the Geoscience Laboratories, Ontario Geological Survey returned a value of 0.02 ounce gold per ton (Carter, 1988).
