The update to the estimate was based on an infill and resource expansion drill program conducted in 2024, the filing said.
The measured resources now stand at 367 million tonnes at 12% grade of titanium oxide and 4,100 ppm total rare earth oxides, while indicated resources came in at 1 billion tonnes at 12% grade of titanium oxide and 4,000 ppm total rare earth oxides.
The measured and indicated resource includes 165 million tonnes of contained titanium dioxide and 5.5 million tonnes of contained total rare earth oxides at a magnet rare earth oxides ratio of 27%, amounting to 1.5 million tonnes of contained magnet rare earth oxides.
The firm is set to report the outcomes of metallurgical test work and the beginning of a scoping study during the ongoing quarter.
