Since 2016, North Line Copper has managed full-scale site operations for Austral Resources, a prominent copper producer in Queensland's Gulf Country. Our team oversees the complete operation of the processing facility at the Lady Annie Mine, providing end-to-end copper recovery solutions. 

From crushing, agglomeration, and stacking to heap leaching of copper oxide and transitional ores, the site also employs advanced hydrometallurgical processes, including solvent extraction and electrowinning, to produce high-purity copper. In addition to processing, North Line Copper provides integrated site management, industry-certified training, HSEQ systems development, emergency response, and on-site industrial medical services — leading a comprehensive, full-scale process operation under one management team. 

Our operational experience across every stage of the mining and processing cycle informs our problem-solving approach today. Although metallurgical processes, including solvent extraction, follow established principles, optimal site performance demands managing the broader operational context—feed variability, reagent management, climatic impacts, and circuit stability. Understanding and proactively managing these variables allows North Line Copper to consistently deliver safe, efficient, and reliable operational outcomes at the Lady Annie facility, producing high-purity copper (99.99%).
