Ann: Firefinch Celebrates First Gold Pour, page-62

Sorry, just like my 72 gold bars, those figures just aren't right.

The 4000-4100oz is for the month of November, not the last 2 weeks.
In Sept they announced Barrick produced in excess of 3000oz.
4,000oz is about 10% above the guidance they gave in the Tailings asx announcement they refer to.

Based on 4000oz a month @ $USD1800oz, AISC $1050, I'd say their after tax profit is:
750 x 4000 x 80% /.73 = A$3.2m
the AISC includes tax - we have credits

Not sure what will happen to the AISC when the satellite ore is blended.
The crushers, ball mill, mining and transport will cost more, offset by the higher grades & higher recovery rate
