Point Location Description: Shaft just south of property symbol 2 west of Highway 62 and northeast of Bannockburn
Location Method: Conversion from MDI
Access Description: Drive to the hamlet of Bannockburn and turn west onto a bush road leading into the old Bannockburn gold mine. The site is approximately 1/4 mile west of the town of Bannockburn on the west side of the Moira River. Bannockburn is 16 km north of the town of Madoc.
1894-1898: Bannockburn gold mine in operation. 1905: The mine closed after being farmed out to an American on a royalty basis. 1894: four shafts were reported to have been sunk on the Property- they were 26, 30, 30, and 45 feet deep respectively. One of the shafts had 17 feet of drifting off of it. A ten stamp Mill was also reported to have been in operation at this time. 1897: The Bannockburn gold mining company deepened the shaft on which the drifting had been started, to 75 feet and new shaft was sunk to 35 feet. 1965: R. Belanger Carried out trenching, 12 diamond drill holes totaling 5,100 ft and sampling on and around lot 28, con. 5. 6 x-ray holes, all 140 to 150 feet in depth were drilled along the ore zone. Highest assays were around 3 oz/au per Ton. The shaft was pumped out and sampled at this time and values of 0.7 oz/au per ton were obtained. 1981-1987: Mono Gold Mines Inc. carried out exploration work including geophysical surveys and diamond drilling in the old bannockburn gold mine area. 1997-1998: Madoc Mining formed a new company, Adobe Ventures Limited, to exclusively develop the Bannockburn gold prospect. Adobe Ventures reported that testing of a 1,800 ton bulk sample trucked to the St. Andrews Goldfields mill in Timmins was not completed. The property was placed on temporary suspension and is currently inactive. (OFR 5992, p5). 2015: Crown William Mining Corp. commissioned stripping, trenching, channel sampling and georeferencing of historic diamond drill collars. This work identified 4 suites of quartz veins 2 of which are gold-bearing; significance of proximity to the volcanic-sedimentary contact; discovery of untested quartz veins. 2016: initiated a relogging and sampling of historic drill core from the Resident Geologist Program Tweed Drill Core Library (OFR6319, p.18).

Jan 30, 2020 (Sheree Hinz) - The prospect is on the boundary of the east extension of a syenite intrusion in the north part of Madoc townships. The intrusion, known as the Gawley Creek Syenite is composed of a coarse-grained pink biotite-hornblende syenite. It straddles the north part of the Marmora-Madoc township. The east side of the syenite is bounded by clastic metasedimentary rock. In a N-S trending shear zone, the syenite has become a biotite carbonate-K-feldspar schist containing lenses and veinlets of quartz and carbonate and disseminated pyrite mineralization. The shear zone is up to 2 m wide and usually contains a series of parallel veins which range in width from 3 to 10cm. The contact between felsic intrusives and schistose metasediments is cut by a vein, strike N78E, dip almost vertical, up to 3 feet wide, which has been stripped for a continuous length of 700 feet.

Jan 30, 2020 (Sheree Hinz) - The sheared syenite contains pyrite in disseminated subhedral to euhedral grains and massive lenses 1-2 cm wide; in localities near veins, the sulphide content is as high as 30%. Mineralized veins are composed of white, massive, medium-to coarse-grained quartz and locally ankerite with up to 10% disseminated pyrite, minor chalcopyrite, and gold. A grab sample of the vein material assayed at 0.17 oz/ton Au. House (1984) reports assays of 0.069 and 0.114 oz Au/ton from surface samples of quartz veins within the main zone.
