RE:RE:RE:RE:Resources Required for a Surface Only Mine - Thoughts? Yes it could be a decent deposit, especially if the deep stuff is there. But it's in the arctic circle. Sandfire can mine year round at it's locations so lower grades can be economical. A copper mine on the tundra that only operates 1/3 of the time is a different prospect altogether so the deposit frankly has to be not just good but great. Again, JMO, YMMV, etc.
