As with the famed Nickel Belt around Sudbury, Ont. - the world's only other
known location in which nickel-rich rock is associated with a major
extraterrestrial impact - confirmation of the Greenland crater means the
valuable metal was likely melted, concentrated and forced to the surface by
the ancient meteorite strike, potentially forming huge and easy-to-extract
deposits.
The only other known location? How about Gallejaur in Sweden? Centrum
lies 30 km from the old nickel mine Lainejaur, mined in the 1940-1950.
It is currently under investigation for new nickel deposits by a new
company that have drilled in the area.

Possibly a 50-60 km crater diameter, placing Lainejaur right at the edge
of the crater.
