Recently, Mineral Resources (MinRes) held a groundbreaking ceremony for its Lamb Creek iron ore project in the Pilbara region of Western Australia, marking the official start of the project's construction phase.

MinRes stated that Lamb Creek is an open-pit iron ore project with a planned annual capacity of approximately 7.5 million mt and an expected mine life of about five years. The project will include the construction of crushing facilities and an approximately 16-kilometer ore haul road. Iron ore products are planned to be shipped through the Port of Hedland. The company expects the project to achieve its first iron ore shipment in Q4 of the 2026 fiscal year (April 1, 2026, to June 30, 2026).

Regarding the overall capacity arrangement, MinRes indicated that upon commissioning, the Lamb Creek project is expected to extend the current production cycle of the Pilbara Hub by more than five years and improve cost conditions. The current operating capacity of the Wonmunna iron ore mine is approximately 5 million mt per year. The company stated that as the Lamb Creek project progresses, mining operations at the Wonmunna iron ore mine will simultaneously enter the closure phase.

It is reported that MinRes released the latest Mineral Resources and Ore Reserves report for the Pilbara Hub in August this year. The report shows that the hub has iron ore Mineral Resources of 161 million mt with an average iron grade of 57.0%, and Ore Reserves of 51 million mt with an average iron grade of 57.5%.

Before the holiday, the black chain is unlikely to see a trend-driven market [SMM Steel Industry Chain Weekly Report].

This week, ferrous metals were in the doldrums, with coking coal and coke staging a mid-week rise. At the beginning of the week, financial markets experienced sharp fluctuations, dragging down sentiment in the ferrous chain and leading to a pullback in futures. Mid-week, Indonesia's cut to coke production quotas drove coking coal and coke futures to lead the gains, though the impact was more pronounced on thermal coal, while coking coal's rise was largely sentiment-driven and short-lived. In the latter part of the week, finished products continued their seasonal inventory buildup, and support from the raw material side weakened, causing the entire ferrous chain to pull back. In the spot market, with the Chinese New Year holiday approaching, purchasing activity slowed down further, with end-users only making limited, as-needed purchases at low prices.
