Ann: Quarterly Activities/Appendix 5B Cash Flow Report, page-4

I didn't get 10-15%.
But alas, I am often wrong and please do correct me.
My figures are 9.1% on the assumption of again hitting their guidance midpoints - $1320/oz and 120,000oz
If the put option fees are hypothetically removed the increase is 7.38% YoY
I sleep easy knowing that 42.5% of our production for four quarters is guaranteed to sell for no less than $2810 oz

YoY guidance increase = $110 x 120,000 = $13.2m
51/120 = 42.5% weighting
$13.2 - $2.55 = $10.7m
$10.7m / 120,000 = $89.16
89.16 / 1208 = 7.38%
110 / 1208 = 9.1%
