Oregon historical mining information available online 

Historical mine and commodities records, formerly available to the public at DOGAMI Portland and Grants Pass office reference libraries, are now available as PDF files in the Oregon Historical Mining Information (OHMI) archive. The first part of this ongoing project includes small-dimension maps, letters, news clippings, photographs, and reports. The agency plans to combine OHMI records with the GIS-based Mineral Information Layer for Oregon (MILO).
