California Time) E-Mail: charles@butlerlab.com Butler Labs Oxyacetylene Torch Assaying. The Torch Fire Assaying Information Page We, here at Butler Lab, have developed an assay procedure to be used as a supplement to furnace assaying of the noble metal ores. It is quick and inexpensive, with most assays requiring 15 to 20 minutes and costing something less than 50¢ each. Since these tests may be performed equally well at home, in the field or laboratory, this procedure becomes very useful to the novice and professional, alike. Most Clients learn the procedure within 10 to 12 hours. Hundreds of clients have learned to assay and leach their noble metal ores, through use of our step by step, instruction manuals, listing all required supplies and their source. Chemicals & supplies available - ask for brochures & price list.

We provide services from laboratory testing to full scale production. 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 ìAssaying Ores, Concentrates, and Bullionî (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: Branch of Publications Distribution Bureau of Mines 4800 Forbes Avenue Pittsburgh, Pennsylvania 15213 USA
