Austral Resources (ASX: AR1) has completed the acquisition of the Lady Loretta mining leases, associated exploration permits and site infrastructure from Glencore, finalising the last pillar of its North-West Queensland copper consolidation strategy.
The transaction leaves Austral debt-free with about $83 million in cash following settlement, repayment of the Rocklands facility, and cash backing of the estimated rehabilitation bond.
The March quarter also marked the successful completion of mining at Anthill, the first production blast at Flying Horse and the start of validation drilling at the Rocklands copper project.
Austral generated about $38.1m from copper cathode sales during the quarter, delivering positive EBITDA and a net operating cash inflow of $6.0m.
Lady Loretta Completes Consolidation Strategy
The Lady Loretta acquisition includes mining leases, associated exploration permits, site infrastructure, and a mining camp.
Under the transaction, Austral received US$40m from Glencore at completion, with about A$14.4m deducted to cash-back the estimated rehabilitation bond.
Austral will assume responsibility for progressive rehabilitation obligations at Lady Loretta and pay Glencore a 2.5% net smelter return royalty on copper oxides and copper sulphides produced from the tenements.
The acquisition strengthens Austral’s tenure position around Lady Annie and adds near-term ore potential through the Lady Annie pit wall cutback and longer-term exploration opportunity across underexplored copper ground.
Lady Annie Cutback Targets Near-Term Feed
Updated pit optimisation and scoping work at Lady Annie has identified additional mineralised material within and adjacent to the current pit footprint.
The work outlined an estimated 1.13 million tonnes to 1.19Mt at 0.51% copper of oxide material with potential suitability for heap leach processing.
It also identified an estimated 1.5Mt to 1.6Mt at 1.26% copper of sulphide material with potential suitability for flotation or toll treatment.
Mining at the Lady Annie cutback is scheduled to commence in the June quarter, providing additional near-term oxide ore feed to the Mt Kelly solvent extraction and electrowinning processing plant.
Anthill Mining Milestone Clears Next Phase
Mining at Anthill was completed during the quarter after final extraction at Anthill East Pit Stage 2.
The final quarter delivered 353,682 wet metric tonnes of ore at an average grade of 0.85% copper, despite a prolonged wet season and increasingly constrained final pit conditions.
Road train haulage from Anthill to the Mt Kelly run-of-mine pad totalled 434,806wmt at 0.75% copper.
With Anthill mining now complete, Austral’s remaining obligation under the Anthill project agreement is the processing of ore over the next 11 months.
Flying Horse Moves into Production
The first production blast at Flying Horse/Mount Clarke took place toward the end of the quarter, marking the start of mining at the brownfields deposit.
Flying Horse/Mount Clarke has a JORC mineral resource of about 16.8Mt at 0.73% copper, depleted to 31 December 2025 and reported above a 0.3% copper cut-off.
The pit moved from care and maintenance to active mining during the quarter, reflecting coordination across operations, technical services and support teams.
Austral expects production to increase materially as Flying Horse and the Lady Annie cutback begin contributing ore during the second half of 2026, although acid supply is expected to remain constrained through to June.
Processing Continues through Wet Season
Austral processed 295,740 dry metric tonnes of ore during the quarter, equivalent to 321,620wmt stacked.
Heap leach operations delivered 1,758t of copper leached, while the solvent extraction and electrowinning circuit stripped 1,990t of copper against quarterly guidance of 2,650t.
Copper cathode purity remained at 99.99% London Metal Exchange Grade A throughout the quarter.
Initial planning also started for the Hydro-Jex remine project, which is designed to access copper inventory in the lower section of the Mt Kelly heap leach pads that was previously inaccessible through mechanical remine extraction.
Rocklands Work Builds Restart Case
Austral commenced an 18-hole reverse circulation and diamond drilling program at Rocklands, targeting the Las Minerale and Double Oxide copper-gold lodes.
The program was initially outlined at about 2,567m and was designed to improve confidence in the existing mineral resource estimate, validate geological and mineralisation controls and define mineralogical characteristics relevant to processing performance.
The exploration team completed a 2,235m validation program almost half a month ahead of schedule and below budget, despite wet season drilling conditions.
Laboratory test work and assays are expected to progress during the next quarter and feed into a full economic reassessment of the Rocklands copper-gold deposit.
Rocklands Processing Options Broaden
Austral is advancing plant optimisation work at Rocklands focused on de-bottlenecking the crushing, milling and flotation circuit.
A key initiative is the planned integration of a semi-autogenous grinding mill, which has moved from high-level to detailed engineering advice and is expected to simplify the circuit while improving reliability and throughput.
The company also executed a non-binding, non-exclusive memorandum of understanding with Metal Bank to assess potential toll treatment of ore from the nearby Millennium project at the Rocklands facility.
The parties will assess metallurgical compatibility, haulage logistics, commercial tolling structures and development timeline alignment, with Millennium located within 20km of Rocklands.
Balance Sheet Supports Expansion
Austral ended the quarter with $60.18m in cash at bank and $52.4m in restricted cash for rehabilitation bonds.
The company raised $65m through a two-tranche placement at $0.09 per share, with the QIC Critical Minerals and Battery Technology Fund committing $15m as cornerstone investor.
A shareholder priority offer targeting up to $5m was also completed after opening on 26 February and closing on 23 March.
Chair David Newling said Austral had continued to execute its strategy through weather and logistical challenges.
“With some highly prospective exploration drilling results, it is an exciting time to be involved with the company,” he added.
