Australian iron ore workers strike at Port Latta plant

Australian iron ore producer Grange Resources is facing industrial action at its 2.6mn t/yr Port Latta iron ore pellet and concentrate facility in Tasmania.

This comes after more than 200 unionised workers voted to go on strike.

Workers from the Australian workers union (AWU) and the communications electrical plumbing union (CEPU) voted in favour of work stoppages of up to two full shifts, with expectations of rolling stoppages across the north Tasmania site. The unions are demanding maintenance workers' pay increases to reflect the higher cost of living across Australia.

The firm undertook major maintenance work at its Port Latta concentrate and pelletising plant in January-March that cut production to 594,000t of concentrate from 668,000t in October-December 2022. The plant was first built in 1967 and requires regular maintenance, with an upgrade to its pellet furnace scheduled to be complete by 30 June.

Grange produced 2.52mn t of pellet in 2022, down from 2.6mn t in 2021, and had hoped to sustain production around 2.5mn-2.6mn t in 2023. It sold 2.43mn t of pellet in 2022, down from 2.51mn t in 2021.

Cash costs rose to A$141.75/t ($94.77/t) of concentrate in January-March from A$124.39/t in October-December 2022. The firm noted that energy costs have begun to ease into 2023, potentially offsetting the wider inflationary environment in the Australian mining sector.

Grange reported an average realised price of $227.93/t fob Port Latta in January-March, up from an average of $141.28/t through 2022. Argus last assessed the iron ore blast furnace pellet price for 63pc Fe and 3.5pc Al at $120.50/t cfr Qingdao on 20 June, down from $138/t on 21 February, but up from a low of $98.50/t on 1 November 2022.

The firm is reviewing its Southdown magnetite project, 90km northeast of Albany, based on expectations of firmer demand for high-grade iron ore over the medium-term and despite weaker prices and rising costs. It has agreed to acquire the 30pc of the project that is held by joint-venture partners Japan's Sojitz Resources and Kobe Steel, with the deal expected to be completed by end June. This will leave Grange, with the backing of its major shareholder Chinese steel producer Shagang, owning 100pc of the project. It has almost 400mn t of iron ore reserves and a Joint Ore Reserves Committee resource of around 1.2bn t.

Grange has scaled down its plans for Southdown to 5mn t/yr of high-grade magnetite from the 10mn t/yr project that was shelved in 2018, and before that in 2012.
