Name of the Project
Garden Well South (GWS) underground gold project.

Location
Duketon Greenstone Belt, in Western Australia.

Project Owner/s
Regis Resources.

Project Description
The Garden Well mine is an operational openpit gold mine, which started production in March 2013, and has standalone crushing, grinding, carbon-in-leach (CIL) processing and tailings storage facilities.

Regis has approved the development of a new underground mine under the current Garden Well openpit, based on a recently completed positive feasibility study on the GWS underground gold project.

The project has total proven and probable reserves of 900 000 t grading 3.4 g/t gold. Measured, indicated and inferred resources are estimated at 2.4-million tonnes grading 3.6 g/t gold.

The GWS underground project will establish a portal and decline off the western wall of the Garden Well openpit, about 130 m below surface. This is located about midway between the natural surface and the final planned depth of the Garden Well openpit of about 265 m below surface. A return air way and escape way will be established by mining vertical raises from the base of the local portal area and then extending laterally with the decline to depth.

Mine development will be undertaken using conventional twin boom jumbos to mine about 11.5 km of waste and ore development over the underground mine’s four-year life.

The existing Garden Well processing plant will be used to treat the material mined from the underground operation using conventional crush/grind/CIL processing.
