The project has already been billed as one of the swiftest to production in the history of mine development in Australia

Primero are an industry leader in the assessment and development of hard rock lithium projects globally. With a deep understanding of lithium mineralogy and subsequent concentration techniques Primero were engaged by the Tawana and AMAL joint venture to complete the design, procurement, construction and operation of the DMS circuit at their Bald Hill Lithium and Tantalum mine in the Eastern Goldfield region of Western Australia.

Priorities for the JV were to gain first mover advantage over their peers and capitalize on heightened demand for spodumene concentrate by fast-tracking the project’s development. Primero were able to deliver on promise in meeting the challenging schedule, reaching practical completion and first concentrate production in March 2018.


Project Highlights 

  • Maiden lithium resource to concentrate production in 9 months, billed as one of the swiftest to production in the history of mine development in Australia.
  • Completed on time and to budget.
  • Incident free.


Two weeks after the production of first concentrate at Bald Hill, Primero’s Operation & Maintenance team exceeded the nameplate production capacity of the plant and are achieving an unprecedented 7% spodumene concentration. These initial results have been achieved with low grade commissioning ore. Bald Hill is the first Australian mine to commence spodumene production since 2016.


Ore commissioning through the newly constructed Dense Media Separation (DMS) circuit made significant progress in the first two weeks of operation. The circuit has performed to expectation with nameplate capacity of 162tph achieved within the first two weeks of commissioning. “Testament to what can be achieved with a great team and a motivated client” says Primero’s Executive Director of Development, Brett Grosvenor “Big thanks to the Bald Hill JV team for their support throughout the project”
