Point Location Description: Diamond drill holes
Location Method: Conversion from MDI
Access Description: The B-Zone is located about 64 km west-southwest of Pickle Lake on the Golden Patricia mine site. The B-Zone is located about 100 m south of the Golden Patricia vein. The Golden Patricia mine is serviced by an all-weather airstrip and a winter road from Pickle Lake.
The B-Zone is believed to have been discovered in 1985 by St. Joe Canada Inc. 1961: New Jersey Zinc Exploration Company (Canada) Ltd. dug several trenches north of the B-Zone. 1963: New Jersey Zinc Exploration Company (Canada) Ltd. drilled 6 diamond-drill holes, totalling 212.78 m, on mineral occurrences north and south of the B-Zone. 1984: St. Joe Exploration Canada Inc. started an exploration program on claims covering the B-Zone occurrence. The work included airborne and ground geophysical surveys, geological mapping, soil geochemistry, trenching and diamond-drilling. 1986: St. Joe Exploration Canada Inc. completed an underground exploration program on the Golden Patricia vein with the driving of 2 declines and the extraction of a bulk sample. A large amount of diamond-drilling was completed on the B-Zone in the same year. 1988: Bond Gold Canada Inc. opened the Golden Patricia Mine.

Dec 07, 2005 (B Nelson) - The B-Zone is a gold-bearing, narrow, partially sulphidized iron formation horizon which trends northwest, sub-parallel to the Golden Patricia vein. It is located about 100 m south of the vein near to the mine workings, but it is further separated from the vein to the southeast. The B-Zone has a strike length of about 1.2 km, but is not consistently mineralized. (Written communication, J. Ackert, mine geologist, Lac Minerals Ltd., 1993). The iron formation is hosted by a succession of mafic metavolcanic flows. The succession is cut by feldspar porphyry dykes. The iron formation is impure with a significant mafic tuff component. Locally, it is intensely folded and strongly fractured with sulphides occupying small fissures parallel to the banding of the iron formation. The sulphides noted in the B-Zone are pyrrhotite, pyrite and chalcopyrite. Overall sulphide content is reported at 2%.
