David,
Buddy I am sorry but I cannot offer a lot of information for you on those claims. I have visited them once while I was in the area and did a little detecting while I was field testing a machine for review.
If you can reach out to the local GPAA Chapter in Redding
http://www.goldprospector...ome/ChapterId/REDDCA I am willing to bet you can get some first hand accounts from members that have prospected the claims.
I hope this helps. Let me know how you do.
Kevin
