Torian's Projects: Introduction
All of Torian’s Western Australian projects are located in the Eastern Goldfields Province of the Yilgarn Craton. Most of the rocks within the tenements are of Archaean age. Such ancient rocks host many of the earth’s major gold, nickel and base metal deposits and have been dated at between 2.5-3.0Ga years old. The famous gold mines at Kalgoorlie which have produced over 70 Moz Au and the huge nickel sulphide deposits at Kambalda and Mt Keith are hosted by rocks of similar ages and origins.
The Archaean rocks of the Yilgarn Craton are broadly subdivided into granites and greenstones. The granites form large, coalescing, ovoid shaped regions up to several hundreds of kilometres in length and width, generally separated by narrow elongate Greenstone Belts composed of ancient volcanic rocks and sediments that have subsequently been deformed and metamorphosed by complex tectonic and mineralising events. Such events are believed to have been responsible for the formation of major gold, nickel and base-metal deposits in a wide variety of rock-types.
