De Grey Mining Limited is an Australia-based gold explorer and project development company. The Company’s activities are focused on the 100% owned Hemi Gold Project in the Pilbara region of Western Australia. Hemi is positioned in the central region of the Company’s 1,500 square kilometers (km2) Hemi Gold Project and is located within 10 kilometers (kms) of two sealed highways, approximately 5 km from a gas pipeline and less than 30 km from an electricity transmission line. The tenement package is highly prospective for gold, other precious metals and also comprises significant base metals resources (Zn-Ag-Pb) as well as lithium prospects. Gold mineralization at Hemi is hosted in a series of intrusions associated with stringer and disseminated sulfide rich zones. Hemi comprises six main zones: Aquila, Brolga, Crow, Diucon, Eagle and Falcon. The Greater Hemi region, located within a 15 km radius of Hemi, includes four intrusion targets: Shaggy, Scooby, Antwerp and Alectroenas.
