De Grey's core business is exploration for gold, silver, base metals and uranium.

Early exploration success saw the company discover and delineate the 220,000 ounce Wingina Well gold deposit at the Turner River Project, near Port Hedland in Western Australia's Pilbara region. Continuing exploration to add to that resource led to the discovery of a virgin VMS-style Zn-Pb-Ag-Au system nearby. De Grey has entered into farm-out and option agreements over the Turner River properties in order to secure exploration funding commitments of $3.5 million over three years.

The Company's Australian exploration interests also extend to the eastern Pilbara, with a 5,340 sq km ground position in the Paterson Province prospective for Kintyre-style uranium and Nifty-style copper mineralisation.

More recently, De Grey has secured exploration rights over 3,800 sq km in the Deseado Massif of Santa Cruz Province, Argentina. The Deseado has recently been recognised as one of the world's premier regions of low-sulphidation epithermal Au-Ag mineralisation. Mineral resources and reserves discovered since 1990 total about 11.5Moz Au and 245Moz Ag.

De Grey also owns significant iron assets.  The Company holds priority rights to the 378 sq km offshore Fortescue Island Project near Cape Preston in the Pilbara and 1% - 2% gross royalties on future iron ore production from certain tenements at Turner River.

De Grey also retains 20% interest in the Beyondie Iron JV where a resource of 561Mt @ 27.5% Fe has been defined and exploration indicates potential to more than double the resource.  De Grey's interest is free carried to decision to mine.

In addition to its established projects, the Company continually assesses new project opportunities for a variety of commodities in diverse locations.
