"Capitalising on the almost daily stoking of the thematic that even the most bullish of the lithium-ion battery boom forecasts are on the light side of things, Altura has pulled in A$26 million from a placement of shares at 19c each to fast-track expansion studies at its yet-to-produce start-up project.
What starts out next year with a rated annual capacity of 220,000 tonnes of spodumene concentrate after the expenditure of $140 million is now being thought of as a 450,000tpa project, probably at an additional cost of around $100 million.
Altura was known to have been exploring its expansion options ahead of achieving first production from its start-up project which gets going in the June quarter of next year.
That it is has raised $26 million to “rapidly progress’’ the expansion study goes to the growing acceptance by investors that the new wave of WA hard-rock lithium producers – Altura, Pilbara Minerals from its adjacent Pilgangoora project, and the Kidman/SQM Earl Grey joint venture near Southern Cross – can comfortably place their product.
And what’s more, the demand curve is there to get serious about their projects being much bigger than originally thought. Apart from Altura’s planning to double capacity, Pilbara is working on a stage two expansion to 800,000tpa from its initial start-up rate next year of 314,000tpa, and Kidman/SQM’s latest scoping study update has settled on a start-up rate in the 2019 FY of 288,000tpa which is at the upper end of an earlier range estimate of 200,000-300,000tpa."
