Sixteen quarries in 1978 and 12 in 1979 had production of less than 100,000 tons per year. Output from quarries in this category was just over 12% of the State's total output in 1978 and almost 8% in 1979. By contrast, the four largest producing quarries supplied more than 68% of the State's total production in both years. Only limestone was quarried. It was marketed as crushed stone. During the biennium, almost two-thirds of the crushed stone was used as aggregates, including those to be used with concrete and bituminous materials for surface treatment of roads and other unspecified activities. 0th- er uses—agricultural stone, riprap and jetty stone, and mineral foods—required from 1% to 5% of total output. Quantities of crushed stone sold for flux, dense roadbase, railroad ballast, asphalt filler, and filter stone were each generally less than 1%. As a commodity of relatively low value, stone tends to be produced as close to the market as possible. Thus, about 84% of all the stone transported in the State was shipped by truck. Railroads handled almost 14% of the stone. About 2% of the stone was carried by waterway, principally, on the Missouri River. Less than 0.5% of the stone was carried by other means.

' Includes stone used in bituminous aggregate, railroad ballast, filter stone (1977-78), cement manufacture, and data indicated by symbol W. 2Data may not add to totals shown because of independent rounding. Talc.—Cyprus Industrial Minerals Co. ground talc from southwestern Montana at its Grand Island mill. The ground talc was sold for use in manufacturing a wide range of personal, ceramic, plastic, and other products. Vermiculite.—W. R. Grace & Co., Construction Products Division, exfoliated vermiculite from Libby, Mont., in its plant near Omaha. Exfoliated vermiculite was used as concrete and plaster aggregate, loose fill and block insulation, for horticulture and soil conditioning, and in fireproofing. METALS at the Omaha refinery of ASARCO Inc., to produce refined and antimonial lead and refined bismuth. The refinery also recovered antimony, antimony oxide, dore containing silver and gold, copper, and zinc. Late in 1978, the firm completed construction and put onstream an automated, enclosed, and environmentally clean plant designed to produce 2,700 tons of antimony oxide per year. Total rated annual capacity of the refinery is 180,000 tons of metal. ' State mineral specialist, Bureau of Mines, Denver, Cob. 2Research geologist, Nebraska Geological Survey, Lincoln, Nebr.
