Anything of that size, cost and depth will be risky especially to a small fish like KZL. we are talking twice the KZL market cap just get it online.
Anyone who is involved with mining will tell you how risky these things are, that's why there is always such a reward if they get it going.
Remember, if there were little risks involved KZL would already be $5 as it would be almost a done deal.
The shaft alone is going to cost $150m they will need underground workshops to re assemble the mining fleet etc once it is underground, the ore will be hauled to the surface and the mining equipment will stay underground, this thing is no small operation and does still have it's technical challenges, anyone who says it doesn't is kidding themselves
