Book Description

Excerpt from Molybdenum Deposits of Colorado: With General Notes on the Molybdenum Industry Soon after it was declared that a state of war existed between the United States and Germany, the Colorado Geological Survey was asked to cooperate with Federal officials in determining the extent of the undeveloped molybdenum resources of Colorado. A notice was at once sent to all the papers of the state, in which information was asked for concerning molybdenite and other minerals which were then, or might later be, needed for war purposes. A questionnaire was mailed to prospectors, mine owners, assayers and others, who would be likely to know about the required minerals, and the writer spent approximately three months in the field during the summer and autumn of 1917 examining molybdenite properties that were reported to the Survey through various mediums of information. It seemed necessary to get certain data with as little delay as possible, and the examination of the various prospects was, therefore, brief and of a reconnaissance nature, but it was sufficient to show that Colorado has very large molybdenum resources, although all the ores arc low grade. Many reports of molybdenite prospects were received at the Survey office after the field work was finished in 1917, and those properties which seemed to be the most promising were examined during the summer of 1918. Purpose of the Report It is the purpose of this report to present a brief statement of the occurrence of molybdenum; to show the present condition of the molybdenum industry; to describe the molybdenite properties of Colorado so far as they are now known; and to indicate the areas in this state that should be prospected.
