Metro Mining Faces Volume Risk From Channel and Workforce Issues

September Shipments Held Up Despite Operational Disruptions

Metro Mining Limited (ASX:MMI) shipped 659,000 wet metric tonnes of bauxite from its Bauxite Hills mine in September, taking year-to-date shipments to 4.013 million WMT. The figure keeps the operation moving, but the accompanying update is less comfortable: Metro has placed its calendar year volume guidance under review after disruptions to both barging capacity and mine-site labour.

The logistics problem emerged mid-month when a sand-bank collapse reduced the barging channel depth from 1.8 metres to 1.3 metres. That constrained barging capacity at the Cape York operation, where bauxite is moved offshore for loading onto larger vessels. Metro had already scheduled a channel maintenance bed-levelling campaign, which began in the first week of October and is expected to restore the channel to its normal approved depth within two weeks.

Workforce Shortages Limited Equipment Use During Ramp-Up

The channel issue was not the only drag on September performance. The mine plan required a ramp-up in stripped volumes, but increased absenteeism and staff turnover meant Metro could not fully utilise all available equipment. The company says measures have been implemented to address the issue, although the announcement does not specify how quickly utilisation is expected to recover.

That operational uncertainty arrives after a strong 2025, when Metro reported record 2025 shipments of 6.2 million WMT. The comparison is useful but not conclusive: the current update provides no revised 2026 target and does not quantify the volume lost to the channel restriction or workforce disruption.

Floating Terminal Performance Improves Recovery Options

There are signs of resilience in the transhipping system. Metro said its offshore floating terminal, Ikamba, is now achieving planned availability and loading at approximately 2,400 tonnes per hour, above target. The floating crane TSA Skardon has also returned after dry-dock maintenance, giving the company additional back-up transhipping capacity when required.

Metro is progressing feasibility studies for a dredging program with Ports North, the government-owned port manager. That work points to a potential longer-term response to channel constraints, but the company has not disclosed an approval timetable or confirmed that dredging will proceed. For now, the nearer-term test is whether bed levelling restores the channel and whether the workforce measures lift equipment utilisation enough to protect the remaining 2026 shipping schedule.
