The Greenbushes mine has been producing lithium from the Greenbushes Lithium Operations for over 25 years. It was established in 1983 and initially focussed on tantalum production but its primary product is lithium. The most recent public lithium resource for the mine was 119.4Mt @ 2.24% Li2O as at 30th September 2013.
The Greenbushes South project is considered prospective for lithium, tin and tantalum. It has similar mineralisation to what exists at the Greenbushes mine.
Most of the project is covered with laterite; which is known to mask pegmatites. However, field reconnaissance and mapping undertaken by Dempsey in and around the old historical tin mining areas has revealed remnant pegmatite characteristic within areas of outcropping lateritic duricrust. Exploration programmes are being planned and will commence upon grant of the tenement. The Company is seeking to expedite the grant.
