The Bureau of Mines investigated the resource potential of 201 mines and deposits in 28 market economy countries and 17 mines and deposits in the USSR and China. The 201 mines and deposits evaluated from market economy countries contain an estimated 34.2 billion metric tons of recoverable phosphate rock (at the demonstrated resource level), with Morocco and Western Sahara accounting for 61% (21 billion tons), followed by the unit with 19% (6.4 billion tons). The 17 mines and deposits evaluated in the USSR and China contain approximately 1.5 Billin tons of potentially recoverable phosphate rock. Potential annual capacity from low- cost, high-grade producing mines in the U.S. is estimated to decline significantly during the latter half of the next decade, and the U.S. Will have to develop new, higher cost, lower grade mines in order to satisfy demand into the next century. Of the world's new production capacity that could likely be developed over the next decade, slightly over one-third could be produced at an estimated 1981 cost of $40 per ton or less, and about two-thirds would cost in the $40 to $50 range (including a 15% rate of return). In comparison, most of the competing phosphate rock from producing mines in Morocco could be produced for under $40 per ton. The U.S. has sufficient demonstrated resources of phosphate rock (plus huge quantities at the identified and hypothetical resource levels) to satisfy domestic comsumption for many years to come, but its future ability to compete in the major export markets against low-cost competitors is much more uncertain.
