Lucky Strike Mine

• A remote fee-digging Lucky Strike Mine is a popular site to collect stunning thundereggs
• Make sure you have the proper direction before you go



Lucky Strike Mine is a remote fee-digging area in the Ochoco Mountain, 26 miles west of Mitchell. This site was discovered and then claimed by a famous miner Leonard Kopinsky in the 1930s, and since remains popular among enthusiastic rockhounds.

The Lucky Strike mine provides a great opportunity to collect beautiful thunder eggs that are well-known for their various colors and styles. The internal cavities are composed of agate containing mosses, plumes, and banding. Some specimens might have hollows with multiple layers of agate including botryoidal agate or quartz crystal.

The digging hillside is located near the mine office and store. The pits are regularly scraped by a backhoe allowing visitors to find great specimens. Bring a rock hammer. If you do not have any tools, you might be able to rent them in the mine store.

Typically, the mine open from Memorial Day to the end of September, depending on weather conditions. You need to make a reservation if you plan to arrive Monday through Thursday.

Make sure you have the proper direction before you go. Do not rely on your smart phone or GPS navigator, it can show wrong routes. Forest roads to this remote part of the Ochoco National Forest are rough, narrow, and winding with sharp turns. So, a high-clearance 4WD vehicle is recommended. Trucks with long trailers should avoid these roads.
