State of Oregon Department of Geology and Mineral Industries 1069 State Office Bldg. Portland Oregon 97201 The ORE BIN Volume 38, No.1 January 1976 OREGON'S MINERAL AND METALLURGICAL INDUSTRY IN 1975 Ralph S. Mason, Deputy State Geologist Oregon Department of Geology and Mineral Industries Oregon's mineral industry declined 15 percent from 1974, reflecting the overall condition of the economy. Sand and gravel and stone, accounti ng for 62 percent of th e tota I, were down 27 percent. Offsetting these losses were increases in clay, pumice, and items that could not be disclosed in the U. S. Bureau of Mines canvass. Despite current high values for gold and silver ,neither commodity was separately identified this year. A table summarizing the State's production for 1974 and 1975 is shown on page 2. Recreational interest in placer gold and semi-precious gemstones continued at a high level as vacationers turned to low-cost outings in the hi lis instead of distant travel. No new major mining operations were announced during the year although several large companies fielded exploration teams for uranium, copper, molybdenum, and gold. Industrial Minerals Although fossil fuels continued to occupy center stage, there was a steadi Iy growing alarm within Oregon over supplies of aggregate. Once regarded as plentiful if not inexhaustible, sand and gravel reserves are now belatedly recognized as finite. In some areas this vital resource will be largely depleted within the next 25 years. Two southern Oregon counties, Jackson and Josephine, have inventoried some of their aggregate supplies under a cooperative arrangement with the Department. Several other counti es are planni ng simi lar studi es to be conducted by Department personnel. In the greater Portland area, competition for land has caused recurrent problems as encroaching urbanization and increased demand for aggregate form two diametrically opposed factions striving t'o use the same land. Both the developer and the aggregate suppli er are necessary for community economic health and growth, but detai led information on the
