Name of the Project
Tampia gold project.

Location
The project is located in the wheatbelt of Western Australia, about 250 km east of Perth, near the township of Narembeen.

Client
Explaurum.

Project Description
A scoping study on the project has shown robust financial metrics over an initial six-year mine life, with low capital and operating costs providing early project payback. The scoping study envisages a single-pit mining operation with a standalone processing plant designed to treat 1.5-million tonnes a year.

The proposed process design is a sequential gravity, flotation and carbon-in-pulp plant that can treat weathered (oxide) ore and fresh (sulphide) ore. A high-intensity cyanide reactor will further treat the gravity concentrate, and ultrafine grinding and intensive leaching will be applied to the flotation concentrate. The combined gravity and flotation concentrates (mass pull) are not expected to exceed 10% of the initial ore feed tonnage.

The tailings storage facility (TSF) is proposed to be located east of the pit and based on the integrated waste landform concept being a clay-lined valley-style TSF located upstream of the eastern waste rock dump.

A preliminary TSF design has been prepared using an embankment ranging from 13 m to 21 m high to progressively provide four-million to 15-million tonnes of storage capacity, with a footprint area ranging from about 50 ha to 150 ha. 

Further storage capacity is possible using additional lifts, with wasterock centreline, or tailings upstream raising methods, so the proposed TSF provides low-cost long-life tailings storage for the Tampia ore and any future satellite resources.
