Australian spodumene developer Altura Mining (AJM-ASX) announced that it was in discussions to be possibly taken over by its major Chinese shareholder. Assuming £1=AS1.75, the current 44 Australian cent Altura Mining share price implies a Mina do Barroso valuation of £67.5m, nearly 25% higher than our previous Altura Mining read through. Altura is a little further advanced than Savannah, with its Pilgangoora spodumene mine in Western Australia just coming on stream.
