Newton Resources hit as rockfall permanently halts operations at key supplier

Newton Resources Ltd announced a significant rockfall incident on October 16, 2025, at the Koolan Operation, a hematite mine owned by its major supplier, Koolan Iron Ore Pty Limited. This incident has led to the permanent cessation of mining operations at the site. Koolan is Newton Resources' long-term supplier, contracted to provide 80% of its total available production annually.

Mount Gibson Iron Limited (MGI) determined that remediation and resumption of mining are not viable due to safety risks, investment requirements, and the Koolan Operation's limited remaining mine life, originally scheduled to conclude around September 2026. Mining activities are suspended, though processing of available ore stockpiles will continue for near-term shipments and potential additional sales from lower-grade stocks.

Koolan has informed Newton Resources of the need to defer several scheduled shipments initially planned for the last quarter of 2025. Newton Resources is currently negotiating with Koolan regarding iron ore supplies and assessing the overall impact, while advising shareholders and potential investors to exercise caution.
