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.

  1. I am very disappointed in this place. My son has been wanting to go here for quite some time and I haven’t had the mo ey to be able to take him. I finally got together enough money to make the trip and surprised him by asking him thrusaday night if he was ready to go. We finished loading up the car Friday morning and we were on our way Friday by noon. I knew it would be closed when we got there so we took ojr time driving the 200 some miles from salem. It was so late when. We got there we drove into mitchel and slept in the car by the highway. We woke up by 9 am Saturday morning. Stopped at the bridge creek Cafe for breakfast and then headed up the mountain towards lucky strike mine.

    We arrived at the mine by 11:30. Their hours were posted as 9-4 Friday to Sunday. But when we got to the gate it said Closed, but the gate was open so we ventured in, when we got to the building at the lucky strike mine we were told they were closed . No explanation. On why or when they would be open. The lady that was sitting there just shrugged her shoulders and waited for us to leave. We weren’t even allowed to get out of the car and look around or stretch our legs. We were all so disappointed with the whole situation that instead of finishing the rest the trip we had planned, we just drove back down the mountain and returned to Salem. We are now sitting back In salem instead of seeing everything else. It will take me another 5 years or more to be able to take my son on another trip like this. But I don’t think he would even go on another adventure. And he says he will never go back to the lucky strike mine. They ruined this memory for a of us.
