Gwalia mass extraction project, Australia
Name of the Project
Gwalia mass extraction (GMX) project.
Location
The project is located south of Leonora, in Western Australia.
Project Owner/s
St Barbara Limited.
Project Description
The Gwalia mine hosts 1.9-million ounces of gold in reserves at a grade of 7.5 g/t.
A February 2018 prefeasibility study proposed changes in mining and haulage methods to suit the Gwalia orebody as it deepens.
A feasibility study has now identified an optimised trucking case as the preferred option to haul ore from the mine, despite having evaluated other haulage methods, including hydraulic hoisting using displacement pumping and hydraulic hoisting using a three-chamber pipe feeder.
The life-of-mine for the preferred trucking option will extend the project life until 2031, at mining rates of up to 1.1-million tonnes a year down to 2 300 m below the surface using the existing Gwalia resources and reserves.
