There's a far simpler explanation as to why they haven't disclosed their cost per ounce...they don't know yet!
Give them a break - end of quarter was yesterday. As they state in the announcement they are still going through end of quarter processes.
Final invoices, adjustments, etc won't be completed until later in the month. Wait till the quarterly comes out and we will find out then what costs are.
This is when they normally disclose quarterly costs and just because the share price has fallen they aren't just going to take a guess at it one day after end of quarter.
