In Greenland min ing is now being planned on a large scale, under conditions comparable to those of the Antarctic. No economically exploitable deposits of minerals have been found in Antarctica, but there is no doubt that large deposits exist. Whether the progress of technology will enable such deposits to be located and economically mined is not clear. Experts confidently state that at present this is not feasible.
