Geological consultant Jim Mungall, Ph.D, Associate Professor from the University of Toronto, visited the Double Eagle project in November. "The large amounts of sulfide and of ultramafic cumulate make it absolutely clear that the Eagle One deposit has formed in a magmatic conduit. No magma could have carried the observed amount of sulfide in solution; therefore the sulfides have been left behind by a through-going volume of magma much greater than what presently remains in the intrusion. If the intrusion is accepted to be a conduit then it must be continuous over considerable distances likely measurable in kilometers

The apparent thickness of chromitite layers at DE2 appear to add more credence to his estimate of the original size of the intrusion.
