Discover current, past, and potential mining activity around the globe on The Diggings—the largest free online resource for mining activity. We combine mining deposit data from Bureau of Land Management (BLM) claim listings to compare where known deposits of gold, silver, copper, and other mineable resources are located alongside where mining activity is (and is not) occurring. Keep up to date with what is happening nearby.
The Diggings™ is your definitive source for the status and ownership of gold, silver, and other mining claims.
The Diggings™ provides data on the locations and status of mining claims on public land. The Bureau of Land Management (BLM) grants individuals and companies mining rights on public land. The Diggings™ is a source to see where these mining claims are and have been.
There are federally administered lands in 19 states where you may locate a mining claim or site. These states are Alaska, Arizona, Arkansas, California, Colorado, Florida, Idaho, Louisiana, Mississippi, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington, and Wyoming. In these states, the BLM manages the surface of public lands and the Forest Service manages the surface of National Forest System lands. The BLM is responsible for the subsurface on both public lands and National Forest System lands.
You may prospect and locate claims and sites on lands open to mineral entry. Claims may not be staked in areas closed to mineral entry by a special act of Congress, regulation, or public land order. These areas are withdrawn from the operation of the mining laws.
The Diggings™ makes it easy to find and map millions of mining claims on BLM public land.
We have indexed an extensive collection of known mineral resources from around the world along with current or past operations occuring around them. Discover where gold and other commodities can be mined or see the extent to which mining activity has already occurred.
A Shifting Landscape
New mines are being filed, auctioned, or resold through private sales. While mines change hands, become active or closed, or have new actions filed, we are updating our records to make this information available to everyone. To be alerted whenever one of these updates is released, join our mailing list.
We are changing too. The Diggings™ is constantly updating and refining content to make it easier to access and add new, useful features for our users. Have an idea of what you would like to see or explore business opportunities? Contact us!

Understanding Claim Ownership
We receive lots of emails from people who find their name or a relative’s name on our site and want to know if this means they have some right to the land listed under that name.
Understanding BLM Administrative Areas
Wether it is filing a mine or researching one, the administering BLM office is going to be the definitive source.
Understanding Location Data
Mine handled by the Bureau of Land Management are not mapped by latitude and longitude, instead, these mines harken back to the Public Land Survey System.
A “township” can refer to two different things. Both are part of the PLSS measurement system but have different uses.
