Exploration History

1936-38: Paulore Gold Mines trenched for 198.25 m, drilled 24 holes totalling 1711.66 m, started a vertical shaft to 100.65 m with levels at 13.73m, 45.75 m, and 91.5 m, lateral development of 297.38 m, and 22 underground drill holes totalling 821.98 m. 1937: Rajah Red Lake Gold Mines drilled seven surface holes totalling approximately 1200 m. 1939: Howey Gold Mines Ltd. drilled two holes totalling 289.32 m. 1944-1946: Redaurum Red Lake Gold Mines incorporated; completed 4575 m of drilling. 1977: Company name changed to Orelock Explorations Ltd. 1978: performed geophysical surveys (magnetometer and VLF-EM) and 2 drill holes totalling 185.14 m. 1979: Completed 6 drill holes totalling 570.1 m. 1985: Redaurum Red Lake Mines Ltd. conducted stripping, a soil geochemical survey, and drilled 15 DDH totalling 5891.4 ft (4 DDH totalling 2121.8 ft on the 14A Zone). 1985: Sabina Resources acquired the property. 1986: Redaurum conducted geological mapping and sampling. 2003: Placer Dome optioned the property from Sabina 2003-06: Placer Dome conducted geological mapping, trenching, soil geochemical sampling, and diamond drilling. 2007: Placer Dome drilled 16 DDH totalling 6213.5 m (2 DDH totalling 921 m on the 14A Zone).

Geology Comments

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 relativeluy narrow and apparently discontinuous bands of iron formation. The Redaurum Zone 14A contains gold in discontinuous carbonate veins in altered mafic volcanics.

Lithology

Lithology Comments

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. The mineral zone consists of strongly carbonatized fault bounded blocks of mafic volcanic rocks. 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.

Mineralization

Mineralization Comments

Dec 07, 2005 (K R Kettles) - The Redaurum Zone 14A consists of strongly carbonatized fault bounded blocks of mafic volcanic rocks. Gold occurs in narrow discontinuous carbonate veins. Pyrite, chalcopyrite, pyrrhotite, arsenopyrite and smaller amounts of bornite, sphalerite and galena are present in the veins. Three trenches, along a strike length of approximately 150 m, returned low gold values. A grab sample of oxidized material from surface assayed 5.4 oz/ton Au, and a channel sample assayed 1.124 oz/ton Au over 1.5 m. However, 10 other channel samples gave low values over 73.2 m. Hole No. 4, drilled by Rajah Red Lake Mines returned one assay of 1.2 oz/ton Au over 1.5 m.

Alteration Comments

Dec 07, 2005 (K R Kettles) - The gold occurs in narrow discontinuous carbonate veins within strongly carbonatized fault bounded blocks of mafic volcanic rocks.
