W. deWeese, Portland, Chairman William E. Miller, Bend Donald G. McGregor, Grants Pass STATE GEOLOGIST R. E. Corcoran FOREWORD Douglas County has a history of mining operations extending back for more than 100 years. During this long time interval there is recorded produc tion of gold, silver, copper, lead, zinc, mercury, and nickel, plus lesser amounts of other metalliferous ores. The only nickel mine in the United States, owned by The Hanna Mining Co., is located on Nickel Mountain, approxi mately 20 miles south of Roseburg. The mine and smelter have operated con tinuously since 1954 and provide year-round employment for more than 500 people. Sand and gravel production keeps pace with the local construction needs. It is estimated that the total value of all raw minerals produced in Douglas County during 1972 will exceed $10, 000, 000 . This bulletin is the first in a series of reports to be published by the Department that will describe the general geology of each county in the State and provide basic information on mineral resources. It is particularly fitting that the first of the series should be Douglas County since it is one of the min eral leaders in the state and appears to have considerable potential for new discoveries during the coming years.
