I have claims there at Blewett also, and have been filed over before! If they haven't worked it no problem... send them a letter "certified mail" and explain that you are the senior claimant and that they will be committing mineral trespass if they remove ANY minerals! Mineral trespass is a Class C Felony! Filing Placer over Lode and vice versa is a touchy subject and should only be done with mutual agreement. There haven't been too many new Location Notices filed recently in Chelan County... I wonder who it was??? Ron in WA
