Drummond Crossing is located 20km north of Eneabba. It is a dunal style HMS deposit occurring at surface. The deposit is 4km long and up to 2.3km wide. Mineralisation extends from surface to depths of up to 30m, with an average thickness of 8m.
On 30 October 2013, Sheffield announced a maiden Mineral Resource for Drummond Crossing of 52.2 million tonnes @ 2.1% HM, containing 1.07 million tonnes HM (Indicated and Inferred).
Drummond Crossing has an excellent mineral assemblage dominated by zircon (14%) and chloride ilmenite (53%), with a significant component of rutile (10%). Visual inspection of the heavy mineral concentrates show a majority of clean grains expected to respond well to conventional mineral processing techniques.
