The company, incorporated in 2004 and listed on the ASX in December 2004, maintains its headquarters at 169 Blues Point Road, McMahons Point, NSW 2060, Australia, and targets self-funding through production ramp-up to 500 metric tonnes per month of copper sulphate pentahydrate alongside ongoing exploration and metallurgical work. Recent developments include the largest-ever shipment of copper sulphate to a major Northern Territory mining operation in 2024 with production enhancements yielding improved product quality and free-flowing crystals low in impurities; a new joint venture announced in November 2025 to explore and develop Queensland Strategic Metals projects; a binding heads of agreement with MT Garnet Mineral Finance for a joint venture mining copper ore from the Tartana open pit for processing at the Mungana plant targeting initial 5,000 tonne production; strategic letters of intent signed for royalty and streaming investments; a proposed acquisition of Queensland Strategic Metals Pty Ltd; and prior rights issues raising up to $1.5 million in 2024 alongside a reverse merger acquisition of Tartana Resources Limited in 2021 that established its core copper focus.
