    Maps showing old mines in CA?

    I'm currently purchasing a property and there's a large pit in the back 40. I had thought it might be an old mine but wasn't to sure and only got to see it for a few minutes when we were looking at the house. In the disclosures it says the house is a 1/4 mile away from sites identified by the U.S. Geologic Survey as a gold placer mine. I'm just trying to see if I can find any info on it or where its at or if that's even an old mine at all. I used to have a bookmark to a site that had an interactive map you could see where old mines were located and a small bit of info on them. I don't have the link anymore and can't seem to find it anywhere. Any help would be much appreciated.

    It might show the old mines on the topo -- then you can change it to google earth view (mouse over box top right side then drop down one box
    and click what you want.)
    Land matters has the info Land Matters California Mining Claims
    Great site with a boat load of info.
    Stay thirsty my friends

    Thanks! I ended up finding it, the marker for the mine is on another property but I think the pit I saw that will be on my property is part of the mine. Looking forward to exploring it in a month

    Is the old mine on BLM land or private? What county? Reason I am asking is I have done a bunch of historical research (thousands of hours at the recorders office and plotting info) and have mapped the original footprint of just about all the mining claims on BLM land dating back to pre-1900's in Nevada, Sierra, and Plumas Counties in CA. If it is in any of those counties, I may be able to help you by referring to my map data.

    It's on private land in butte county. The mine itself is on the neighbors property, or at least the coordinates show it being on their property. It was an open pit mine though and the pit extends a couple hundred feet into my property. We get the keys this week so if I got time between moving I'm gonna go check it out a bit. I only got to see it once when we walked the property and haven't gotten down there since.

    Well been here for 3 months but between moving and dealing with the camp fire I havent had much time to get out and prospect. But I finally managed to get out with my brother in law yesterday for an hour between cooking and panned a spot on the property. All the rain filled the pit up pretty good and theres a seasonal stream that was running enough to pan in. Click image for larger version.

    Nice looking pan, how much material did you do for that amount?

    I'd say it was about 15 pans between the 2 of us. Where I was digging I was getting a lot of small stuff and a few bigger flakes and my bother in law was digging a few feet further down from me and kept getting pans with 3-5 of those larger flakes and tons of black sand. I went down there the other day with my boys and explored the pit a bit, that chunk next to my foot was hard as a rock. Once the rain came though it softened up and was pretty easy to dig into.

    Time to break out one of those bazookas if the creek flow is sufficient.

    Good luck

    If it can't be grown, it must be mined!

    1st thing you need to do is see if the mineral rights are part of your property deed, if not find out how to file for them quick.

    A placer in my literal backyard would mean I need a small wash plant and a good used backhoe and water, even if I had to have a well drilled to fill a pond....I'm so jealous

    Haha that's exactly what I was thinking. I was also thinking a dredge might be usable here, its not in a waterway so I'm guessing it's legal, they have a setup like that down at roaring camp.

    I didn't know that was possible, what's the process to obtain that?
