"AISC was $797 across 39,607 = $31,566,799 in costs
We sold 39,607 ounces at $1,315 = $52,083,205 in revenue

That gives us profits of $20.52m USD, convert this to AUD and we have 26.99m AUD (at an fx of 76c)

We also have 7,248 ounces of unsold gold valued at $1,316 and an fx of 0.76 = 12,717,824

So total of this is roughly 39.70m AUD."

Good to see people questioning all figures from companies.

I really think you need to take into account the whole production figure as stated in the Q.
48,000 or close to it was produced not 39600 and that unsold gold will be sold on top of further production.
Really you need to spread any cost over the whole production figure when talking costs and profit.
That extra profit may not be realised just yet but the cost of it has and you should be using that when talking costs and profit.
