Tuckabianna Project

 mine, gold mine

The Tuckabianna project is 100% wholly owned by Silver Lake Resources and is situated approximately 25 km east of Cue in the Murchison Province of the Archaean Yilgarn Block and this is the main portion of the tenement. The project consists of 15 granted tenements covering 238 km2. This project is part of Silver Lakes greater Murchison Goldfield focus area whhich is located between the multi-million ounce gold producing areas of Mount Magnet and Cue, 600 km northeast of Perth. Murchison assets consist of the Tuckabianna, Comet and Moyagee projects.

Between Measured/Indicated/Inferred Resources Total Resources for Murchison Goldfield include:

-18,370,000 tonnes Ore
-2.8 grams/tonne
-1,650,000 total Oz

Gold was discovered at Tuckabianna in 1915 with intermittent small scale production from rich mineralised pods within the hostbanded iron formation ("BIF"). During the period leading up to the commencement of modern open pit mining operations in 1988, total gold production was 53,000 oz at an average grade of 18 g/t Au.

Between 1988 and 1997, approximately six million tonnes of ore was treated from the Tuckabianna area for a total production exceeding 500,000 oz Au. Most of this production came from 17 different open pits located within Silver Lake’s project area.

Gold mineralisation at Tuckabianna is mostly developed within brittle zones associated with well laminated BIF units. Gold is also found along the margins of quartz-feldspar porphyry dykes and in narrow isolated rafts of BIF within the greenstone stratigraphy. These mineralised zones are interpreted as having resulted from faults which cut the stratigraphy at a low angle. Gold is generally associated with quartz-carbonate-pyrite-pyrrhotite stringers developed within these zones.

Silver Lake’s project area covers a significant strike extent of a regionally extensive shear zone, the north-northeast trending Moyagee Shear, which sub-parallels the Lena Shear to the east. In the eastern portion of the project area, gold mineralisation is spatially associated with the Tuckabianna Shear, which is regarded as a low angle splay off the Moyagee Shear.

Between Indicated and Inferred Resources Total Resources for Tuckabiana include:

Tuckabiana Open Pits:

-8,220,000 tonnes Ore
-2.2 grams/tonne
-570,000 total Oz

Tuckabiana Underground:

-2,430,000 tonnes Ore
-4.0 grams/tonne
-310,000 total Oz
