The Virginian - Season 4 Episode 4 The Claim

Trampas becomes discouraged with being a ranch hand and sets off with an old friend, Luke Milford (William Shatner), to Deadwood City in the Dakotas where gold strikes are reported. They learn that most of the gold is off limits in Sioux territory but they meet and help a man named Finley (Strother Martin) who claims to have a gold strike outside of Indian land and who agrees to cut them in if they will stake him for equipment. They do strike gold but it turns out it is on Indian land. Trampas runs into trouble not only with the Sioux but inevitably ends up in a showdown with Luke who has become fixated on finding and retaining the gold.
