RCT Case Study: Mandalay Resources - Costerfield Operation, Victoria

This was originally published by RCT.

Overview

Canadian mining company Mandalay Resources owns and operates the Costerfield gold antimony project southeast of Bendigo in regional Victoria, Australia.

Costerfield produces ore via a single portal underground mine with site personnel using a narrow vein method to extract vertical veins of ore.

The mine produces up to 80,000 equivalent ounces per annum in gold and antimony in gravity gold and a concentrate compromising approximately 54 per cent antimony and 60g/t gold.

The nature of narrow vein mining dictates that ore drives are quite thin to reduce the amount of waste material that is captured.

Costerfield’s drilling and blasting program was designed to maximise ore recovery by throwing the ore towards the draw point, however, historically the site could only recover 75 per cent of the ore.

This was due to the remaining ore sitting in the stope void out of reach of the underground loader as manually operated loaders could not exceed the stope brow.

Mandalay then investigated implementing a loader that could be managed remotely to extract additional ore and to safeguard equipment operators from hazardous situations at the mine face.

“Relocating operators from the cab of our loaders to safer environments on the mine’s surface is essential, and being able to continue bogging during firing as well as significantly reducing shift changeover time is critical to improving site productivity. Plant automation is definitely the way of the future in the mining industry and RCT are the leaders in that area, which is why they are our preferred supplier with this equipment,” - Jayson Guzzo, Major Projects and Innovation Manager – Costerfield, Mandalay Resources
