Just North and a lil East of Weippe are two GPAA claims. The Chomco Revised-EFG (cl114) and the Nahkohe Morning Star (cl115). I did a drive-by last fall just to see if I could locate them. I did. This spring I will set up my 2.5" Keene highbanker/dredge and see what's in there.
Also, if you are familiar with LR2000, you can find several placers just East of Weippe on Lolo Creek and area.
