Dec 07, 2005 (K R Kettles) - Much of the Redaurum property is underlain by mafic metavolcanic flows and a few mafic to ultramafic sills and/or dikes. Rock units generally strike east-west and dip steeply to the south. Adjacent to the strong NE striking lineament extending from Paulore Lake along Dam Creek, the mafic flows have been almost completely altered to massive carbonate. A thin band (150 m) of felsic volcanics outcrops in the north-central part of the property. Intercalated with both the felsic and mafic volcanics are several relatively narrow and apparently discontinuous bands of iron formation.

Dec 07, 2005 (K R Kettles) - Adjacent to the NE striking lineament the mafic flows have been almost completely altered to massive carbonate. Country metavolcanics are also silicified next to the deposit. A few mafic to ultramafic sills cut the mafic volcanics. A thin band of felsic metavolcanics occurs to the north. Minor bands of iron formation are intercalated with both the felsic and mafic metavolcanics.

Dec 07, 2005 (K R Kettles) - Gold with minor arsenopyrite and chalcopyrite occurs in quartz stringers and silicified mafic metavolcanics. The altered mafic flows are adjacent to a strong NE striking lineament extending from Paulore Lake along Dam Creek. Assays as high as 0.14 oz/ton Au were reutrned from the zone, but values were generally lower.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanics which host the stringers of quartz, carbonate and gold are almost completely altered to massive carbonate, and have been silicified as well.
