At this link is my EduMine course on Mine Closure: The Basics of Success. One issue I do not address in the course is a looming tendency, namely should we tax existing mines to pay for closure of old mines?
This evening in a Vancouver pub, I drank the evening away with friends of forty and more years vintage. We have all been involved in mining for that many years and have seen our share of closed mines and mines that will never be closed. We drifted inexorably to the Giant Mine in Yellowknife, Northwest Territories, Canada.
Here is what I read today about the closure of that mine:
“A northern review board has given its conditional stamp of approval to a federal cleanup plan for an abandoned gold mine near Yellowknife.
The main environmental hazard at Giant Mine is the 237,000 tonnes of highly toxic arsenic trioxide dust stored in 15 underground chambers — there’s enough to kill every person in the world. The arsenic trioxide is a byproduct from decades of gold mining.
