From our Ore to Your Door - Episode 1 - Exploration and Geology
Our Kunwarara – Yaamba deposit extends for around 30km, as one of the world’s largest deposits of cryptocrystalline magnesite.
The Kunwarara mine produces around 3 million tonnes of ore annually.
We screen and wash the ore on site, then send more than 400,000 tonnes of higher quality ore to the Parkhurst plant to be processed into quality magnesite products.
We mine selectively across the site to achieve the perfect blends.

The Kunwarara magnesite deposit was discovered in 1986. Over several years, our geologists skillfully mapped out the broad location of the ‘Mag Seam’: the magnesite-containing layer beneath the surface, using broad-spaced drilling.
Once the Mineral Development License was obtained, substantial infill drilling began. This was to ‘fill in the blanks’ of the broad-spaced drilling, to assess what was truly below the surface. This process still happens today as we continue infill drilling for detailed mapping of all ore.
Today, our geologists work with management to assess the reserves and find newer areas to mine, to meet our mining schedule. Geologists also research what ore types will be needed in the future and explore both inside existing Mining Leases and in new areas.

Safety is not a component of our business, rather safety is an outcome of business.
From our Ore to Your Door - Episode 8 - In Pit Screening
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.
