Dec 07, 2005 (C Papertzian) - The property is underlain by late Precambrian calcareous sediments of the Grenville Structural Province. The deposit occurs in a quartz vein within the calcareous sediments and is related to a late precambiran felsic intrusive (the Deloro Stock) located to the east of the deposit. The vein is mineralized with arsenopyrite, pyrite and chalcopyrite.

Notes: The property was first visited on November 19, 1999. No outcrop was visible. The dump material, which was approximately 20 feet high, contained arsenopyrite, quartz, and calcareous metasediments. A grab sample was collected from the dump material and was sent to the OGS lab in Sudbury. It was analysed for both gold and silver. Gold assyed at 0.05 oz/ton, while silver was not detected. This site was to be rehabilitated in the winter of 2000. A second vist was made to the property on March 14, 2000 after the rehabilitation work was completed. Both shafts had been capped and are now marked by a vent pipe. The dump material was used to cover the shaft caps.
