Don't forget, total recovery, (never 100%).
Purity, (never 100%)
Cost to produce each ounce, around 50%
of gold price, or higher.
They're not giving any projected g.p.t. to be processed,
therefore, can only (guess) at a few grams per tonne. (average).
NEVER gat 100% recovery, gold is only around 90% pure,
and production/labour costs would be around $1,000 per ounce.
85tpd x 7days =595 tonnes.
2gpt = 1,190 gms through put.
minus 10% not recovered = 1,071 gms.
1,071 / 31.1034 (gms per oz) = 34.43 ozs gold
Multiplied by approx. 90 % purity = 30.99 ozs
Profit after $1,000 of production costs, approx. $800 per oz.
$800 x 30.99 = $24,792.
That's all with 100% plant availability, (NO BREAKDOWNS) [not likely].
Plus downtime for regular maintenance ?????
If grades are better than 2 gpt av. will get better results
Vic. gold is often 95/96% pure, also better.
Production costs (MAY) be less than a $1,000 per oz.
This is all information that AUL is NOT being forth coming with.
Showing some HIGH GRADE hits, but over what TOTAL depth????
Following grades are across 15 metres, maybe 3 holes.
But how much dirt has to be processed to extract those grades?
They're NOT SAYING!!!!!
Nearly 10 metres @ 67gpt is excellent, but how much waste ore to get at it?
"• 1.10m @ 171.84 g/t Au. including:

• 0.78m @ 150.68g/t Au
Don't forget that these grades are over a an approx. 50 mm diameter core,
NOT over a square mtr area.
You can drill a hole, get a results of 100 gpt, but drill
all the rest of a square mtr patch, with the holes all next to each other,
and come up with ZERO gpt.
