Austral Resources Australia Ltd (AR1) reported a transition in its operational focus at the Mt Isa Operations in Queensland during the June 2026 quarter. The company reached a significant milestone by completing the haulage of ore from the Anthill mine to its Mt Kelly processing facility. Mining activities have now successfully shifted to the Lady Annie lease, marking a deliberate move toward the next phase of the company's production schedule.

Production data for the quarter reflected this operational rotation. Austral reported copper cathode output of 1,796 tonnes, generating approximately $31.0 million in sales revenue. Despite this income, the company recorded a net operating cash outflow of $6.8 million, influenced by increased mining costs associated with establishing these new mining fronts. Following the end of the quarter, the company terminated the Anthill Project Agreement, a structural change intended to simplify its operating model and secure full control over its own copper production going forward. Consequently, the company plans to restate its 2026 calendar year operating performance metrics in the upcoming September quarterly report to provide a consistent baseline for shareholders.

In parallel with mining activities, the company is pushing forward with the restart program at its Rocklands facility. A key component of this effort is the acquisition of an unused 4.75MW SAG mill, which was secured to facilitate a crushing and grinding circuit upgrade. Delivery of this equipment to the site was scheduled for late July 2026. This upgrade, managed through a front-end engineering design study with GR Engineering Services, is a cornerstone of the company’s plans to expand its processing capacity.

Exploration efforts also yielded results during the quarter, highlighted by a high-grade copper-gold discovery at the Snow Queen prospect. Drillhole 26SQRC001 intercepted 10m at 7.52% copper, 9.28g/t silver, and 0.25g/t gold from a depth of 35 meters. This discovery has prompted an expanded follow-up drilling program to further evaluate the mineral system. Additionally, the company identified a copper oxide system at the Canyon prospect, located approximately 4km from the Mt Kelly processing plant.

Looking ahead, the company is balancing these growth and restart initiatives with near-term production targets. While sulphuric acid supply constraints slightly impacted heap leach performance in the June period, management expects production rates to reach targeted levels by mid-November 2026 as supply chain discussions progress. The company ended the quarter in a stable position with $71.6 million in cash at bank, providing the necessary liquidity to continue these development activities across its Queensland tenements. The combination of transitioning mining fronts and planned infrastructure upgrades at Rocklands remains the central focus for the company as it moves into the second half of the year.
