Death Valley Days

The Bandits of Panamint (1x15)

:

While fleeing a posse in Death Valley, two outlaws discover a rich vein of silver. Since they're too well known to file a claim, one of the bandits convinces his girlfriend, Gwen, to file for them. Gwen goes a step farther and arranges for a U.S. Senator to arrange for immunity for the two bandits in exchange for the claim and cash. When Wells Fargo claims the money for past hold-ups, the crooks decide to go back into the robbery business, but the senator and their girlfriends have other ideas.
