Gold price, page-6879

Hi all
Just doing some maths, advice to see if I'm on the right track. Bin might be able to help I think he runs spreadsheets

I'm using the company guild and the lower figure on 145k oz and the higher aisc of $815
145 x 815 = 118175
If we have done 56 k oz at $1055 that's 59080 then that leaves 89000 oz with 59095 (118175 - 59080)
Which would put the aisc for then remaining 89k oz to be $663 per oz for the second half to meet the guild on the lower end of oz and the high end of aisc. Does this make sense?

If this sound right even if we only do 45k oz in the sept quarter and I would say we averaged $1320 per oz that would be 1320 - 663 x 45 = $29 m profit

Are these figures reasonable?

Thanks
Mic
