Point Location Description: Diamond drill holes
Location Method: Conversion from MDI
Access Description: This occurrence is located about 63 km south-southwest of Pickle Lake and about 3.7 km southeast of the Golden Patricia mine. The occurrence is in a group of intersections from diamond-drill holes spotted in the mouth of a small bay at the northeast end of Muskegsagagen Lake. Access to this occurrence is by appropriately equipped aircraft to Muskegsagagen lake. The Golden Patricia mine to the northwest has an all-weather air strip and is serviced by a winter road which passes northeast of Muskegsagagen Lake.
1984: St. Joe Canada Inc. commissioned an airborne mag survey over the occurrence area. 1986: St. Joe Canada Inc. and Geocanex Ltd. commissioned separate airborne mag and EM surveys over the occurrence area. 1986: Joint ventures funded by Power Explorations Inc., Moss Resources Ltd., 669977 Ontario Ltd. and Oracle Resources Ltd. did ground mag and EM surveys, geological mapping, rock and soil geochemistry surveys on a claim group covering the occurrence. 1986 and 1987: Power Explorations Inc. did 36 diamond-drill holes, totalling 3448.8 m, on a claim group covering the occurrence. A fence of 5 diamond-drill holes tested the occurrence.

Dec 07, 2005 (B Nelson) - Three of the 5 diamond-drill holes that tested this occurrence intersected narrow gold-bearing zones at the contacts between mafic metavolcanic flows and quartz-feldspar porphyry intrusions. The gold-bearing contacts between the 2 rock types are silicified and sericitized and, in the case of the richest intersection, sheared. The gold-bearing zones typically contain 2%-5% pyrite, but the highest grade assay was reported from a zone containing an estimated 20% pyrite. In all intersections the quartz-feldspar porphyry intrusions contain disseminated pyrite mineralization and return anomalous gold values when assayed.
