Mining activities commenced in 2001 and the mine's production came to an end in 2013. At Hillendale, dunes with a high fines content were mined to recover the valuable minerals of ilmenite Zircon and rutile. The fine fraction consisting mainly of fine clay minerals was managed by storage in a residue storage facility (RSF).
