Mining Claims in the USA
There are two main types of mining claims in the United States:

US Gold Detecting FAQs
Do I need a permit to metal detect for gold on BLM land?
Generally no for casual recreational prospecting with hand tools. However, motorized equipment or significant earth moving may require a Notice of Intent. Always check with the local BLM field office.
Can I metal detect in national parks?
NO. Metal detecting is strictly prohibited in all US National Parks. This includes historical parks and monuments. State parks vary by state - always check first.
What about ghost towns?
Many ghost towns are on federal land and detecting may be allowed. However, some are protected historical sites. Check with the managing agency (BLM, Forest Service) first.
