MAS Files (Mineral Availability System/Mineral Assessment Studies)
The Minerals Availability System (MAS) was a US Bureau of Mines program begun in the early 1960’s to measure and classify identified mineral resources according to their extraction technologies, economics and commercial availability. The files contain information on occurrences, deposits, mines and processing facilities. When the US Bureau of Mines was closed in 1996, the US Bureau of Land Management (BLM) was given responsibility for the Alaska MAS files located in Juneau and Anchorage. Those files in BLM are known as AMIS, Alaska Minerals Information System. The MAS files are arranged numerically by quadrangle number and indexed by quadrangle and property.
