Point Location Description: PROPERTY (OCCURRENCE)
Location Method: Conversion from MDI
Access Description: The property is located approximately 50 km east of Dryden and 19 km south of Borup's Corners. The property is accessed by: taking Highway 603 south from Highway 17 at Borup's Corners, for 14 km; then south-east along an old Canadian Pacific Forest Products hauling road for 5 km. The various showings are accessed by means of recently constructed bulldozer trails which traverse eastward from this latter road.
The area has been extensively explored for gold in the past. There are numerous gold occurrences, prospects and past producers located nearby. No previous exploration has evaluated the industrial mineral potential of the area: 1991 to 1994. The occurrence was discovered by A. Glatz and A. Kozowy. A total of 136 claim units covering 8 miles of strike-length were staked. Prospecting, stripping and sampling was conducted on the property. 1994 A. Glatz and A. Kozowy still hold the property.

Dec 07, 2005 (R Degagne) - The occurrence lies within a contact zone between the Revell Batholith and the Stormy Lake greenstone belt. The zone roughly parallels the contact with the batholith and contains a mixture of granitic and intensely altered volcanic material. Large amounts of quartz, fluorite and sericite are present at numerous locations on the property.

Dec 07, 2005 (R Degagne) - The occurrence has been exposed through backhoe stripping but it wasn't possible to get a true width of the mineralization. The fluorite mineralization is said to extend over 4 km. Five showings have been excavated over the 4 km strike length. Showing No. 5: A 46 m x 20 m area has been exposed. Two rock types occur, a massive quartz-rich granitic looking rock and a fine-grained sericite-muscovite-fluorite +/- pyrite schist. The schistose rock presumably is the remnants of the host volcanic rocks which have been intensely altered. Showing No. 4: This showing is a small outcrop of granite with sericite on the side of a ridge. Fluorite is seen along with trace pyrite. Apparently A. Glatz obtained 0.15% W from assays. A bull white, barren, 3 m+ quartz vein is located south of the showing. Showing No. 3: The showing consists of a large stripped outcrop. Fluorite is seen throughout the outcrop up to 1-2% with localised variations. The fluorite occurs primarily within the sheared sericitic schist. To the south is a large mass (25 m diameter) of apparently barren quartz. Showing No. 2: This is the highest grade showing and is seen as a 1.5 m wide zone of fluorite-sericite schist in contact with a 1 m wide quartz vein. Up to 40% fluorite is seen in the zone over a strike length of 25 m. A quartz vein is exposed over 10.7 m in the trench and contains chloritic xenoliths. The xenoliths represent fragments of the host metavolcanic rocks. Showing No. 1: This showing is exposed on a cut base-line, it is the site where fluorite was first discovered by the property owners. A quartz-sericite-chlorite-fluorite schist is in contact with a 2-3 m wide quartz vein which strikes 310 degrees. Generally, fluorite comprises up to 5% of the rock, however, higher-grade sections are seen. A. Glatz reported molybdenite and fuchsite at this site (which were observed) and corundum ( not seen). Fine-grained pyrite (trace) was also seen.
