Exploration History

The original Bannockburn Gold Mine operated prior to 1894 and from 1894 to 1898. This mine was farmed out to an American on a royalty basis, and lasted until around 1905. In 1965, Mr. R. Belanger carried out trenching, diamond drilling and sampling on and around lot 28, con 5. 12 dd holes, representing 5,100 ft. were drilled. 6 x-ray holes, all 140 to 150 ft 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. From 1981 to 1987 Mono Gold Mines Inc. carried out exploration work - geophysical surveys and diamond drilling in the old Bannockburn Gold Mine area in 1981. In 1983 adjoining claims were acquired. In 1984 a new geophysical survey and geological mapping were carried out over all of the claims. This resulted in the discovery of a gold-bearing quartz vein system to the N.E. In 1985 a dd program started. 7 dd programs continued to early 1987 outlining a 1500 ft. long quartz vein system. 41,000 ft of dd completed to March 1987. In 1987 stripping and a bulk sample taken on the main vein. In 1988 an underground exploration program was started with Micham Explorations Ltd. Ramp sunk to the 75 ft level - 5,700 ft of dd. in 35 holes completed from 3 underground bays. In 1988 dd was completed to test the down dip extensions of the vein. In 1993 Canadian Mono Gold Mines attempted to extract a 10,000 ton bulk sample but were unsuccessful. Madoc Mining Co. drills in 1996 and 1997- 17 additional dd holes. In 1997 Canadian Mine Force in conjunction with Madoc Mining began underground work to acquire a 2,000 ton bulk sample from the main vein. Mined material was shipped to the Horne Smelter in Noranda, Quebec.

Geology Comments

Dec 07, 2005 (C Papertzian) - In the N.E., the discovery zone is underlain by mafic to intermediate metavolcanic rocks, semi-pelitic metasediments with sulphide-bearing semi-pelitic metasedimentary phases, and minor intrusive rocks. Most of the N.E. area is underlain by banded, fine to medium grained sericitic and silicieous semi-pelitic metasediments that are strongly deformed and isoclinally folded about the nose and axis of the S.W. plunging antiformal structure that dominates this area. The metavolcanics of the Tudor Formation are generally mafic to intermediate, massive greenstones. They are moderately folded, chloritic and exhibit several alteration types. The felsite zones represent zones of metasomatic alteration, or migmatization, and may be related to granitic or syenitic intrusives at depth. ( G. House, 1989) The original Bannockburn Au Mine lies within a northerly trending, vertically dipping shear zone at the contact between the Gawley Creek syenite stock and siliceous metasedimentary rocks to the east (Hewitt 1968). Within the 6 ft wide shear zone, the syenite is altered to biotite-carbonate-potassium feldspar schist containing veinlets of quartz and ankerite and dissminated pyrite mineralization. The veins are 3 to 10 cm. wide, and contain up to 10% pyrite with minor chalcopyrite and gold. The mineralized zone has been exposed in trenches and four shafts over a strike length of 700 feet and intersected in diamond drill holes for an additional 300 feet along strike. The main shaft is 75 feet deep with a 10 to 20 foot drift on the 32 foot level (Malczak et al 1985).

Site Visit Information

Date: Nov 27, 2000

Geologist: C Papertzian

Notes: This deposit was visited on June 6 and 8, 2000, as well as on October 3rd, 2000. The main portal was accessible along with the raise. All visits were in relation to the safety aspect of the mine site. To date the problems have not been mitigated.

Date: Aug 29, 2002

Geologist: C Papertzian

Notes: This deposit was visited on July 15th, 2002. The main portal was not accessible but the fence enclosing the raise had been breached. All of the coverings over the raise, fencing, sand and boards were in place. The visit here, was in relation to the safety aspect of the mine site.
