Underground mining is expensive and riskyI am GPY holder here. Please note, your AZG underground mine is expensive to operate, risky and everyday is exposed to risk of collapse and rockfall. Your miners need to be paid more, expensive equipment and extra spending on structures needed to reinforce mine shafts, and energy to ventilate the mines continuously, including all the monitoring. Don't tell me you want to work there!
To support costly underground mines, the gold grades need to be stupidly high... like what is it now. Don't think your high grades are worth much, if it cost even more to get them!
Majority of open pit, heap leach projects are sub 1g/ton gold but way way way cheaper than underground mines, and much more profitable!
