Kalgoorlie secures major project status renewal

Ardea Resources says that its Kalgoorlie Nickel Project in Western Australia has secured a crucial renewal of its major project status from the federal government for another three years, underscoring the project’s strategic importance, granting it streamlined approvals and direct access to the country’s major project facilitation agency. Located 80 km from Kalgoorlie, the project hosts what Ardea says is the world’s largest undeveloped nickel-cobalt resource, containing 854 million tonnes averaging 0.71% (6.1 million tonnes) of nickel and 0.045% (386,000 tonnes) of cobalt.

The company is currently working towards publishing a definitive feasibility study on the project, which is fully funded by Ardea’s heavyweight Japanese partners Sumitomo Metal Mining and Mitsubishi Corporation. A 2023 pre-feasibility study envisages producing 30,000 t/a of nickel over a 40 year project lifespan, using high-pressure acid leach (HPAL) technology. Partnership deals are in place for 75% of the project offtake, for use in electric vehicle (EV) battery and stainless steel markets.

Managing Director and CEO Andrew Penkethman said: “On behalf of Ardea, I extend my sincere thanks to the Australian Federal Government and the Major Projects Facilitation Agency for renewing Major Project Status for the KNP. This renewal reaffirms the strategic and economic importance of the Kalgoorlie Nickel Project. It ensures continued support in streamlining regulatory pathways, enhancing approvals coordination, and maintaining access to project-enabling funding avenues.”

Coromandel starts trial operations at new acid plants

Coromandel International says that it has started trial production at its new sulphuric acid and phosphoric acid plants in Kakinada, Andhra Pradesh. The company says that this marks a crucial step towards transforming the unit into a fully integrated facility, significantly enhancing production capacity and diminishing reliance on imported raw materials for fertiliser manufacturing. The company is now focusing on a phased ramp-up. The new plants have of 2,000 t/d of sulphuric acid and 650 t/d of phosphoric acid, respectively. The integration of these acid plants is strategic, aligning with Coromandel's objective to strengthen backward integration in its fertiliser manufacturing value chain. By producing key intermediates in-house, the company aims to secure stable supplies, enhance cost efficiencies, and achieve greater self-sufficiency, thereby reducing dependence on imported raw materials. The project aims to replace over 50% of the Kakinada plant's imported acid requirements and mirror the integration levels seen at its Vizag and Ennore facilities.
