A silly contention here. They can't work for 3 months due to rain but it is superior because it is mineable year round?
As long as a deposit is large enough and of high enough quality it can be mined anywhere. If it's good enough they will find a way to mine it wherever it is.
Any project that relies on marginal economics will just trade dollar for dollar until it fails. They all do.
Their flagship project is a dud and will go nowhere.
