The operating expenses for last three quarters totaled 9mil AUD approx.

The quarterly for MUS is due very soon, im gonna say they spent a bit more this quarter due to the ramp up
Thats 4-5mil AUD?

In which case we are looking at about $13-$14mil (AUD) or (10mil USD) in operating costs to date.

Based on 400,000crts thats around $32.5-$35 AUD per crt ($25 USD) (thats rough calculations)

Its hard to distinguish how exporation and evaluation is broken down (from an accounting perspective) but for simplicity ive just used the entire amount of OPEX as a guide.
