Rox Resources reported on 7 September 2026 that construction and underground mining at the Youanmi Gold Mine in Western Australia remain on schedule, with first gold targeted around the middle of 2027.
Plant construction advances
Bulk earthworks have been completed across the processing plant area for the planned 1.0 million tonne-a-year facility. Rox said the screen plant concrete works and crusher foundation are complete, while the primary crusher walls are under construction.
Foundations for the ball mill and ISAMill have been poured, the fine-ore-bin tunnel pour is complete and work on the Albion Process tank ring beams is starting. The carbon-in-leach pad has also been completed, with tank erection continuing.
Several long-lead items are moving towards site. Albion tanks left their fabrication location in late August and are due in Perth in late September, while primary, secondary and tertiary crushers are in transit. The limestone ball mill and rock breaker are already in Perth.
Underground development builds
Mining contractor Barminco completed 577 metres of development in August, comprising 431 metres of advance across three mining areas and 146 metres of stripping in the historic Youanmi decline. Development has started towards the first production levels at Youanmi Main.
At United North, the escapeway network has been raise-bored to the 2325-metre level, with ladderway installation planned during September. Rox expects production stoping to begin in October, subject to final assays and updates to the grade-control model.
Site services and next steps
The camp expansion is complete, providing 351 rooms, and the wastewater treatment plant and dry mess have been commissioned. Work is also progressing on mine dewatering, the tailings storage facility, workshops, services and conveyor footings.
The company said its near-term priorities include continuing underground development and stockpiling, finalising the oxygen supply contract and satisfying the remaining conditions for drawdown under its project debt facilities. Youanmi has a global mineral resource estimate of 12.1 million tonnes at 5.6 grams per tonne gold for 2.2 million ounces.
