Gold price, page-13270

To me head grade will be the key. Beadell was guiding December quarter head grade of 2.2g/t. This was going to drive the ASIC down to ~US$700/oz.

From the annoucement 22nd Dec 2017:
"The shortfall is due to a short-term deferral of high grade ore of >2g/t gold from late December 2017 into early January 2018 due to minor operational factors."
This is a red flag. It's not just that the amount of ore mined will be lower due to some hard rock, the grade will be poorer than forecast as well. The word "deferral" means they intentionally decided not to mine the good stuff. Make up your own mind about that.
