OzAurum Resources Limited has advanced construction across its low-capex heap leach development pathway at the Mulgabbie North gold project in Western Australia, shifting from its initial January 2025 water abstraction licence application and February 2026 plant acquisition phases into active site preparation.

The company holds the Mulgabbie North Gold Project, backed by a Mineral Resource reported at 260,000 ounces of contained gold across a 4km mineralised trend. Construction of two production water bores is underway within the granted Mining Lease to support Stage 1 and provide flow testing for Stage 2 development. The new 120-metre-deep bore replaces an existing 66-metre bore. Securing water within the lease removes a key development risk compared to the initial application lodged in January 2025 prior to securing subsequent approvals for 450,000 kilolitres per year.

"A critical aspect of the heap leach operation is water supply, and I am confident that we will have sufficient water supply within our immediate Mining Lease that will significantly reduce the capex and opex aspects of the water supply for our proposed heap leach."

— Andrew Pumphrey, CEO and Managing Director

In parallel, the majority of the heap leach and agglomeration plant has been transported from Polaris Engineering Services in Henderson to a Kalgoorlie staging point. This follows the January 2026 plant acquisition and February 2026 appointment of Polaris Engineering Services to refurbish the equipment. Site foundations have cured sufficiently to receive the plant upon its arrival.

"Shifting the heap leach plant from Perth to Kalgoorlie and then to site results in a significant cost savings and makes the logistics a lot more manageable."

— Andrew Pumphrey, CEO and Managing Director

Site civil works are advancing under an owner-operator model using company-owned and dry-hired equipment. Topsoil stripping and site road upgrades are complete, while excavation of 13,000 bank cubic metres for the ponds is scheduled to begin shortly. Permitting is substantially complete following the receipt of major environmental and water approvals, leaving the dangerous goods permit under assessment with the Department of Mines, Petroleum and Exploration as the final requirement before health department poison permits can be lodged.

Plant installation is scheduled to commence as soon as the heap leach plant arrives on site, while upcoming flow testing will evaluate water flows for Stage 2.
