The two companies, which are planning to merge in December, already have an offtake agreement with Hong Kong-based Burwill Commodity but are seeking additional partners as they consider increasing plant throughput to 300 t/h from around 200 t/h.
Tawana said during a presentation delivered at the Technology and Low Emissions Conference in Perth that it has completed a fines optimisation study and is now adding a third dense media separation circuit to increase plant flexibility and treat material ranging in size from 0.5mm-18mm.
An increase in plant throughput to 300 t/h is also aimed at increasing recoveries to 72-80pc. This is expected to increase production capacity by 110pc when compared to Bald Hill's pre-feasibility base case of 161 t/h and recovery levels of 65pc. The expansion is expected to bring significant benefits to operating costs.
Bald Hill produced 28,419t of lithium concentrate in the July-September quarter and is expected to export 55,000-60,000t to its offtake partner during July-December. It produced 36,000 lbs of tantalite in July-September and completed its first tantalite sale in October.
