Exploration History

Circa 1930s: The immediate area was explored for gold leading to the development of the nearby Johnston-McKenna-McCann prospects. 1981: Showing discovered by M.W. Carter while he was doing mapping for the OGS. 1983: Claim TB 699002 was staked by G.H. Coyne. All interest was transferred to Lobo Exploration Co. Ltd. as part of a larger claim group. 1984: A combined airborne geophysical (EM, VLF-EM, magnetometer) survey was conducted by Aerodat Ltd. 1985: Lobo Exploration Co. Ltd. changed its name to Camber Exploration Co. 1986: Camber Exploration conducted a geochemical soil survey. 1995: Phantom Exploration Services Ltd. was contracted by J. Ferguson to carry out magnetic and VLF-EM surveys.

Geology Comments

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.

Mineralization Comments

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).
