Point Location Description: Diamond drill holes
Location Method: Conversion from MDI
Access Description: The Esker Zone is located about 61 km west-southwest of Pickle Lake and about 4.75 km east-southeast of the Golden Patricia mine. The center of the zone is about 550 m northeast of the northeast shore of Muskegsagagen Lake. Access to this occurrence is best gained through the Golden Patricia mine which is serviced by an all-weather airstrip and a winter road from Pickle Lake. Appropriately equipped aircraft may land on Muskegsagagen Lake to the southwest of the occurrence.
1984: St. Joe Canada Inc. commissioned an airborne magnetometer survey over an area including the occurrence. This was followed up with a ground mag survey over an area including the occurrence. 1985: St. Joe Canada Inc. did ground mag, EM and IP surveys and diamond-drilling around the occurrence. 1986: St. Joe Canada Inc. and Geocanex Ltd. did separate airborne mag and EM surveys over areas including the occurrence. 1986: St. Joe Canada Inc. continued diamond-drilling around the occurrence. 1988: St. Joe Canada Inc. / Bond Gold Canada Inc. did additional geophysical surveys around the occurrence and did the diamond-drilling which located and defined the Esker Zone. 1989 and 1990: Bond Gold Canada Inc. did additional diamond-drilling on and around the Esker Zone.

Dec 07, 2005 (B Nelson) - The Esker Zone is two zones of gold mineralization in close proximity to each other. The first zone of gold mineralization is contained within a silicified and sulphidized portion of an iron formation horizon. The iron formation occurs in a succession of mafic metavolcanic flows. The Esker Zone occurs in a thicker portion of the iron formation and has a strike length of 60 m. A fold closure may have caused the thickening of the iron formation. Quartz-feldspar porphyry intrusives cut the mafic metavolcanic flows. The gold-bearing portion of the iron formation is typically strongly deformed. Often it is cut by blue-grey quartz veins and stringers. The principle sulphide in the zone is pyrrhotite, with pyrite, arsenopyrite and chalcopyrite as accessory sulphides. The second zone of gold mineralization is contained in a zone of biotite-carbonate alteration within the mafic metavolcanics. Locally, the zone contains a blue-grey quartz vein and / or pyrrhotite, but neither are necessary for gold to be present. It is not certain if this second zone is one entity or several erratic occurrences of gold.
