"operating costs may rise depending on where they are mining "
A very good point, which is often overlooked. Those with a keen eye will note that variations in Qtrly production costs are indeed influenced by the economics associated with several factors, including: Total material mined Total ore mined Ore processed
When we se a "drop" of say 17% (or a rise of 17% for that matter), it does not automatically mean that is due to variations in efficiency of processing, or some other "improvement" (or inefficiency) that the company has recently achieved / realised. A significant part of the cost variation, in my view based on the various factors noted above, is essentially as you mentioned Mr Winkle - "where they are mining".
Just imo a very relevant and important consideration to remember when we receive new figures on costs etc.
