Reports and analyses on elemental sulfur, fluorspar, magnesite, and aluminous chromite were reviewed for the purpose of identifying and categorizing the known deposits, and to indicate those which seem to merit further study on the basis of available information. General conclusions drawn from the study are: (1) Although aluminous chromite deposits exist, no minable deposits of refractory-grade material have been made found to date; (2) small but minable reserves
of elemental sulfur, fluorspar, and magnesite are available; (3) detailed mapping, prospecting, and sampling are required to fully assess the ore reserves in known deposits, and (4) field examination of some of the other deposits described herein may call for additional exploration which may eliminate them from further consideration as minable deposits. The sulfur deposits at Koh-i-Sultan volcano in the Chagai District of Quetta Division are the only assured source of elemental
sulfur in Pakistan. Indicated reserves are 85,000 tons of less than 50 percent sulfur ore of solfataric origin. The deposits are currently being mined.
