Rox Takes Youanmi Water Works Underground

Why It Matters

The water removal reopens a former gold-producing area, allowing Rox to assess remaining reserves and extend its production footprint in a low‑cost jurisdiction. Successful dewatering also mitigates safety risks and demonstrates operational expertise in challenging groundwater conditions.

Key Takeaways

• Rox removed ~1.8M cubic metres of water from Youanmi pit
• Exposed historic decline and pit floor for resource assessment
• Dewatering enables future mining extensions at the historic site
• Improves safety and reduces groundwater pressure in the pit
• Strengthens Rox's position in Western Australia's gold sector

Pulse Analysis

The Youanmi gold mine, once a prolific producer in Western Australia’s Mid West, ceased operations in the early 1990s after its underground workings were flooded. In 2023, Rox Resources acquired the dormant asset with a strategy to unlock residual gold through modern techniques. Completing the dewatering of the Main pit marks the first major step in Rox’s revival plan, as the removal of roughly 1.8 million cubic metres of water has exposed the historic decline and pit floor that have remained inaccessible for decades.

Dewatering a pit of this scale presents engineering challenges, including managing groundwater inflow, ensuring slope stability, and preventing environmental contamination. Rox employed a combination of high‑capacity submersible pumps, temporary bulkheads, and real‑time monitoring to safely extract the water while maintaining compliance with Western Australian environmental regulations. The exposed rock faces now allow geologists to conduct detailed mapping, core drilling, and metallurgical testing, providing a clearer picture of remaining ore zones and informing the design of future underground development or open‑pit expansion.

For the broader mining sector, Rox’s success illustrates how legacy sites can be re‑energized with relatively modest capital outlays, offering a low‑risk pathway to augment production in a region already known for its stable regulatory framework and skilled workforce. The project also aligns with ESG trends by reducing water‑related hazards and improving site safety. As Rox moves toward resource definition and potential mine planning, investors will watch for updates on reserve estimates, which could boost the company’s valuation and reinforce Western Australia’s status as a gold powerhouse.
