Leached Outcrops of Northern Manitoba
THE study of leached outcrops as an aid in determining the character of mineralization beneath the surface is in its infancy. Practically all the work on this subject up to the present has been applied to the 'porphyry' copper deposits of the southwestern United States. Some work has been done also on the zinc-lead solid sulphide deposits of the western United States.
