Rather than more drilling, Cashflow could be gained quickly by reworking Einsleigh.
Surely the Einsleigh deposit could be put in production quickly. .83Mt @ 3% copper at $9285 per tone $Aud with a convservative 70% recovery give a gross cashflow of $156 million. Conservatively it might cost $80 million to process this. Leaving a net cashflow $74million.

It is only back of the envelope calcs. Any comments welcome??
