Hi Stevelap
Without thinking too much some ideas which come to mind would be North to Alaska and the subject of claim jumpers.
Another one would be The Spoiler with Harry Carey and John Wayne opposed by Randolph Scott
One of the Monogram films with John Wayne and Gabby Hayes owing a gold mine
and a long shot War of the Wildcats about oil fields and Albert Dekker trying to do John Wayne and the Indians out of their oil fields.
Regards
Arthur
