Mineral Property Files
The Idaho Geological Survey maintains files on several thousand mining properties in the state. These files include the reports made by companies to the State Mine Inspector from 1899-1962, as well as donated material from the mining industry and private parties. Some files contain consulting reports and mine maps. Most are unique documents, and many are in fragile condition. Available files are organized by 1-degree x 2-degree quadrangle and property number, and can be found by searching our Mines and Prospects Database.
We are in the process of scanning our collection of Mineral Property Files, and many documents are not yet available electronically. The Survey provides digitally scanned copies of records in its Mineral Property Files in the form of downloadable Adobe PDF documents. Each order is assessed an initial processing charge of $10.00, plus $0.50 for each letter size and legal size sheet in the file (pricing subject to change based on effort required). We no longer offer photocopy services, nor scan individual sections of the whole property file. An estimate of the expected delivery time is given at the time of the order.
