Bemax Resources Ltd operates the Ginkgo mineral sands mine located 35 km west of Pooncarie in far western New South Wales. Large 'start-up' overburden stockpiles are present at the mine site and will remain after closure. The first overburden stockpile to be constructed and revegetated is overburden stockpile OB3, which covers an area of 34 ha. Material characterisation studies by Landloch Pty Ltd provided detailed information on runoff and erosion potential of the outer batter slopes, underpinning recommendations with respect to batter profiles, heights, and gradients, and surface treatments such as placement of tree debris to control wind and water erosion. Associated trials have shown the value of tree debris in reducing impacts of sand movement on emerging seedlings. Perimeter and cross bunding to manage runoff from the top of the landform were also recommended.
