Pilgangoora output could increase to 5Mt/y

Lithium developer Pilbara Minerals was considering increasing the output at its Pilgangoora lithium-tantalum project, in Western Australia, after a 15% increase in the total proved and probable ore reserve. The ore reserve was now estimated at 80.3-million tonnes, grading 1.27% lithium oxide, 123 parts per million tantalum pentoxide, and 10.8% iron oxide.
