Hi Dawn, I received and replied to your email but will provide a summary of the response here. If anyone wants more information feel free to email at coldwaterprosepecting@gmail.com
During my search for my own claim met many people and organizations. Ultimately found my claim listed in the ICMJ Prospecting and Mining classifieds. https://www.icmj.com/ Suggest subscribing if you don't already.
Rick Solinski at Western Mining Alliance will help you locate and file a claim. They also sell claims. Finding your own claim is much cheaper than buying but takes time. https://theminingalliance.com/index.php
Brodec Location Services has many claims for sale. They are located in Nevada County and many of their listings are in this area which is closer for me. I sampled three of their claims but did not buy one (yet). https://brodec.biz/
Advanced Geologic is a good organization too. Charlie helped me with a reclamation bond and have nothing but good things to say. Reviewing their listings and miles to drive they were all a bit too far for a day trip and prices tended to be north of my budget.

Of course sample, sample and sample. Don't be afraid to walk away.

If you are still reading this post congrats as most people don't read till the end. Feel free to email me if you have any questions.

Happy Prospecting.
