Altura, which currently has 1.54 billion shares outstanding, will also issue the providers of the debt with 72.6 million shares.
Pilgangoora has previously been projected by Altura to generate earnings of A$1 billion (on an EBITDA basis), over a 13-year mine life.
Altura’s modelling used a spodumene concentrate price of US$539 per tonne, with prices earlier this year of $900/t being reported.
Pilgangoora’s cash costs have been estimated at A$316/t (FOB), with the project to produce about 220,000t of concentrate annually.
Earlier this month Altura signed a binding offtake for a minimum of 100,000tpa with its largest shareholder – Chinese battery manufacturer J&R Optimum Energy – while also being set to supply a similar amount of concentrate to “lithium product specialist group” Lionergy.
Altura joins Pilbara Minerals in securing finance, with the latter last month completing a bond issue for US$100 million for its own Pilgangoora project.
Shares in Altura were up 3% to A16c in early trade, capitalising the company at $246 million.
