I agree that we can soon expect to receive a quarterly update on the production at Murchison.

From the 3rd Dec update:
Outlook - Production in October was lower than plan however output improved during November as the effect of the aforementioned initiatives took effect. It is expected that production will continue to improve and meet plan in December.

The Quarterly Activities and Cashflow Report issued on 31st Jan contained this:
Murchison Gold Mine, WA – gold production increased
- Ramping up production
- Production accelerated in January as operational
improvements take effect
- High grade ore source from NOA 2 brought on line

Overall my assumption would be that production and costs are by now close to reaching the target figures that were previously announced. Were the most recent predictions here in the 31st Oct Quarterly Activities and Cashflow Report?:

If that assumption is correct what would be a reasonable valuation of the company?
