The deepest hole in the world, on the Kola Peninsula in Arctic Russia, is open for business. Addressing an international seminar on deep drilling in Murmansk last week, A. I. Krivtsov of the Soviet geology ministry suggested forming an international company to exploit the research potential of the hole. The borehole, begun in the 1970s, has now reached 12 261 metres.
