Bald Hill Mine

Alliance has 100% ownership of the Bald Hill Lithium and Tantalum Mine which is located 50km south east of Kambalda in the Eastern Goldfields region of Western Australia. It is located approximately 75km south east of the Mt Marion Lithium project and approximately 350km by road from the Port of Esperance.  The Project comprises mining tenure totalling 774km2.

The Bald Hill hard rock lithium operation  boasts a top quality +1mm spodumene concentrate (low mica, low iron) and a significant tantalum by-product production.

The project was commissioned in March 2018 with initial spodumene concentrate production capacity of 155ktpa and first lithium concentrate shipment was completed in early May 2018. Studies were recently completed for a low capex (A$10-12m) plant upgrade at Bald Hill.

Exploration activities have been limited in recent times as focus has been on mine development, but with operations now firmly underway, drilling activities are anticipated to ramp up in 2019.


The Bald Hill project was traditionally first explored and mined for tantalum. It was during mining, that pegmatite ore containing varying amounts of spodumene was discovered.

Bald Hill has total lithium resources of 26.5Mt at 1.0% Li2O (using 0.3% Li2O cut off) and 149ppm Ta2O5 and additional tantalum resources of 4.4Mt at 336ppm Ta2O5.

Bald Hill has a lithium ore reserve of 11.3Mt at 1.0% Li2O and 160 ppm Ta2O5 – representing an increase of 105% in contained lithium from the July 2017 reserve estimate.

Tantalum ore reserve of an additional 2.0Mt at 313ppm Ta2O5 – an increase of 43% from the July 2017 reserve estimate
