Its Detour Lake which has produced well over 5 million ounces since opened in 2013 and still has over 20 million ounces in its gold pantry and still counting.
There are substantial others in Canada too....
Perhaps you might inform the Detour Group that your analyses of the current 20 million ounce Resource that their masterclass open pit mine contains, indicates that those 20 million ounces cannot be economically mined.
Copy their reply on this BOD but leave out all curse words..
