This Arizona Department of Mineral Resources publication describes fluorspar deposits in Arizona, history and production, types of deposits, grade specifications and marketing conditions. Total production of Arizona fluorspar from 1902-70 is estimated at 33,900 tons valued at $ 980,000. This report is possible through the efforts of Mr. E. A. Elevatorski. The wording, geology, interpretation and analyses are his. Described herein are 96 fluorspar mines, prospects, and occurrences. During the period, 1966 thru 1970, E. A. Elevatorski visited and examined 56 of the properties. Where possible, all properties are located on maps, according to section, township and range. Considerable effort was made to describe routes of access to each property so that they can be visited with a minimum of effort.
