'Mineral shortage in offing unless wastage is stopped' May 16, 1973 THE LITKBRIDCE HiRALD S3 By HAROLD M. SCHMECK Jr New York Times Service WASHINGTON-The United States faces severe minera shortages in the next few dec ades unless the nation stops wasting resources and begins to employ better ways of find ing and expoliting low-grad< ores, according to a report from the U.S. Geological Sur vey. The 722-page report, release; recently, is the first overal assessment of U.S. mineral use and resources in 21 years. The document covers everything from abrasives to zirconium including coal, oil, natura gas and industrial metals. Th< survey noted that all of civili zation, not only the U.S., relies on mineral resources. "The real extent of our de- pendence on mineral resources places in jeopardy not merely affluence, but world civiliza said the editors of the volume. In a foreword, Rogers C. B Morton, secretary of the inter ior, said the question of the magnitude of usable resources is of mounting concern. He noted that minerals and min eral fuels are "literally the cornerstones" of modern life A summary statement re- leased by the department with the report, said the nation's known deposits of mineral raw materials are seriously de- pleted and-that future supplies must come, in many cases from low-grade ores or from resources that are yet to be discovered. Perserverance finally paid off Women's lib finds Mrs. Muriel Wood, 55, doing 'business on the floor of the London Stock Exchange, the first of her sex in its more than 170-year his- tory.

Newsmen wanting a voice clip phone the service collect and three or four statements from ministers are fed over the line. The service will cost the gov- ernment about a month. Pays for comic book SACRAMENTO, Calif. (Reu- ter) Mitchell Mehdy, an 18- year-old high school student, said here he paid for one of nine existing copies of the comic book that introduced Superman" to the world in 1938. The Berkeley Oomic Art Shop said that the price is the high- est ever paid for a rare comic book. "For many minerals our fu- ture production will depend on the mining of huge volumes of low-grade ores with adverse environmental impact unless we exert great care in their extraction and said Dr. V. E. McKelvey, director of the U.S. Geological Survey. It is a unit of the department of interior. The report noted that in- creasing dependence on low- grade ores also means in- creasing cost in money and use of energy. "The reader should bear in the report said, "that as the mining industry turns to lower and lower grades of many ores, the cost and avail- ability cf the required energy are probably the single most important factors that will ul- timately determine whether or not a particular mineral depos- it can be worked economical- ly." The report said the U.S. now imports 29 per cent of its oil and gas requirements, about one-third of the iron ore and 87 per cent of the aluminum the nation uses annually. Imports account for only a small portion of the two mil- lion tons of copper used annu- ally in the U.S., but the re- port said our known resources would be used up in 45 years at current rates of consump- tion. Known world supplies should last about 50 years. Beyond that, the survey said, consumption, here and abroad must depend on discovery of new deposits and on deveolp- ment of new methods for ex- tracting very low grade ore. The United States produces about nine per cent of the world's zinc, but uses three times that much. The metal is relatively plentiful on earth, but the report estimates that between 1950 and 1970 the world used half of all the zinc ever produced up to that time. "The phenomenal increase in the production and consump- tion of zinc in the 20th cen- tyry cannot continue indefin- itely and eventually produc- tion must decline as primary resources approach exhaus- the report said. This downward trend is not expected for several decades, but the survey suggested that the industry should seek im- provements and innovations in its techniques to prolong its survival. In terms of quantities used, iron, aluminum, copper and rinc are, in that order, the meet important industrial mst- Without them, modern in- dustrial society would be hard- pressed to survive in its plea- sant state. The fifth most widely used mstal, manganese, the United States has no known reserves and little prospect of finding major deposits that could be used economically. The last manganese mine in the U.S. closed in 1970. Toe metal is in- dispsnsible to steel production. "The element is essential to the whole industrial capacity of the said the report. "When we can do without steel, we can do without mangan- The survey said world sup- plies are large in relation to consumption, but are irregu- larly distributed. In the case of this metal, as in several other minerals, the document said there is a need for more ex- ploitation of undersea resourc- es. Many other used in relatively snail quantities, are nevertheless essential to indus- trial civilization. In many of these too, the survey shows that the United States is using much more than it produces. In mercury, for example, do- mestic production is less then one-third of needs and the out- look for discovering rich ores was rated poor. The use of silver in the United States in photography alone amounts to more than total domestic production. The geological survey's docu- ment said that much valuable mineral raw material was be- ing wasted. It said billions of cubic feet of the industrially important gas helium are being wasted because it is not being removed from natural gas. "A major aspect of resourc- es that appears k many of these said the intro- duction to the is the extent to which many poten- tial by-products are being wast- ed lost forever because there is no apparent economic incentive for recovering them." The report disavowed both the prophets of doom who sea the end of civilization in sight and the optimists who believe greater need will continue to beget greater supplies forever. Much remains to be learned about the amounts of earth's mineral resources that can be made valuable for human use, the report said. Calcualtions from proven reserves are mis- leading, it said, because new discoveries are presumably still to be made. On the other hand, the document noted, "ele- ments are available in the earth's crust in very finite amounts." are something special in the special world of children.
