Ann: Corporate Presentation - July 2019, page-12

8 If you are really interested, take a listen to the earnings call. Yes the increased ore grade played a role in lowering costs of production but there were half a dozen other important factors as well. You are focusing on one element to extrapolate future costs while ignoring significant other factors in my opinion.
GXY expects costs of production to be maintained along with the SC6.0 grade output going forward due to continued improvements of those other factors. The results of the quarter are not a one off.
