US Government



Bureau of Mines / US Department of the Interior

The Federal Bureau of Mines, although it attempts to avoid duplication of the services rendered by state agencies, is authorized to give advice regarding prospective markets. It does not compete with private assayers and chemists, but it will accept samples sent to its field laboratories and identify them by visual or microscopic inspection. This examination is usually sufficient to indicate whether or not the material has commercial value, or at least, if the expense of an assay would be warranted. Except in connection with its own technical investigations, no assays or other special tests are made by the Bureau of Mines.

A free booklet called "Assaying Ores, Concentrates, and Bullion" (Information Circular 8714r/Bureau of Mines) is available, which provides basic information about various testing techniques available to the public at commercial laboratories; chemical analysis, optical emission spectrographic analysis, fire assay analysis, x-ray analysis, atomic absorption analysis, and neutron activation analysis.

This information booklet also provides some information on the procedures for obtaining ore samples, prices for assaying, and a partial list of commercial assay laboratories. A general statement of policy regarding the Bureau's mineralogical services that are available to the public is included in the Federal Register.

This government office can help greatly and provide information concerning subjects such as prospective markets and assaying. To receive the above information booklet (IC 8714r) contact your local office or write:
