RE: CU market overheated?
Short term there is a shortage of supply but the world has no shortage of copper in the ground.
In a number of years there will be plenty of supply coming on. The countries who have mineable deposits and get their mines developed now will be the real winners. 5? years from now when there is plenty of supply, mines that didn't get developed will not be developed due to lack of robust pricing.
If Mongolia refuses to offer incentives to get mines developed now it could well be 20 years before they get another opportunity to have their mineral resources fully developed.
Mines only get developed when their are compelling economics.
