@Theinvestmentjourney, my interpretation of your graph is different.
Basically, I think the legend on this graph works like reading some text: From left to right and top to bottom.
Each row is a more “expensive” production cost (higher AISC). So start on the first row and move towards the right, once you finish with a row go onto the next row starting from the left again.
That would men that Petropavlosk is where the big red arrow is, which means its AISC is over 1000 USD pero ounze, which significantly larger than the average:
Therefore I would say that they are on the wrong end of the cost curve. Either way, with rising gold prices (if it continues to rise) it should not be a problem.
P.S. If I happen to have mis-interpreted the graph then please let me know .
