The mine is located east of Cullinan with a 7 million tonne weathered granite sand resource in situ. AST is currently developing the resource to supply washed sand of - 8mm + 75µ from site with less than 3% sub 75µ material (clay).

Typical feed grading from the resource is assumed to be 100% passing 1.18mm and 13% passing 75µ. AST uses CDE hydro-cyclone technology and delivers high quality washed sand of all sizes above 75µ.
