From our Ore to Your Door - Episode 7 - Mining Operations
QMAG currently mines 4 million tonnes of ore per year, from six to eight different pits. We choose pits based on their magnesite content and contaminant concentrations. There are always at least two pits mined simultaneously to provide the Parkhurst plant with enough material at suitable quality to support our full suite of products.
When we come to the ore mining process itself, the mining is relatively straightforward. The first step is to dewater the ore body in preparation for mining. Next, a 120-tonne excavator and haul trucks relocate to the pit to mine the ore in a series of 2-3m deep benches. The top bench depths are chosen based on anticipated quality. The bottom bench is different. The excavator operators uses their keen vision and experience to follow the contact between the orebody and the underlaying sandstone, as it can change rapidly. Ore is loaded onto the haul trucks and transported out of the pit. At the KG1 mining area, ore is split between the processing plant and in-pit screen stockpiles. At all other mining areas, all ore is brought to the in-pit screens.

From our Ore to Your Door - Episode 6 - Mining Pit Development
With exploration, drilling and planning complete, it’s time to start mining. First, surveyors stake out the boundary of the area to be mined. A clearing permit verifies that the area to be mined is within the active lease, has
been cleared by the local Land Council, and has the correct government permit to be mined. Now the pit development can begin.
Visitors to Kunwarara
We were thrilled to welcome Matthew Canavan and Michelle Landry to our mine last week! It was an exciting opportunity to give them an in-depth look at our "Ore to Your Door" process and share the remarkable stories of the local businesses that enrich our community.
The falcons are back!
The final days of winter saw some wonderful news at QMAG’s Parkhurst facility in Rockhampton, Australia – the much loved (and respected) resident peregrine falcons are nesting!
