Historic Mines & Mining Companies: Get Started

What You Can Expect

Of the thousands of mines, mining companies and processing operations in the US, most are abandoned and left few records. It can take a bit of detective work to find the Information that's still out there.

Relatively easy finds:  Information about "famous" mines; property and claim records; regional production data and geology; mining districts; existence of a company and stock values

Difficult to find:  Production figures, assay records for a specific mine; lists of employees; information about the equipment and surface operations; maps of underground workings.
