The Mine with the Iron Door is a 1924 American silent Western film directed by Sam Wood and produced by Sol Lesser.
As described in a review in a film magazine,[2] Bob Hill (Murray) and Thad Grave (Woodruff), two aged prospectors, find a little girl in the hut of bandit Sonora Jack (Lewis) and take her away, but are unable to locate her parents.
When Marta (Mackaill) grows to womanhood, Hugh Edwards (O'Malley) appears on the scene, and they fall in love.
Edwards saves his life and in return Natachee shows him the location of the lost mine with the iron door, formerly worked by the Dominican priests and filled with gold.
[4] In 2010 the French copy of the film was tracked down by historian Demion Clinco and shown by the Tucson Historic Preservation Foundation at the Rialto Theater.
