Oooookay - let's see here. 

So.. Virginal Maiden type- plucky kind of innocent (or is that naive? This is noir) girl who desperately wants her father's murderer to be found. 
Mine owner baddie - money grubbing type with a desire to either make MORE money, take out cowboys who can't keep their nose out of someone else's business, wants a piece of virginal maiden, or some complex concoction of one, two, or all of the above. 

A town, regular old boom town, on the verge of really making it now that the railway is come, but with a dark hole up there on that mountain. Said about thet ol'  place how it was a sacred prayer spot to some injun tribe or some such. Ain't no good diggin' inta th' belly of thet thing, I'm tellin' ya. Some miners, they go in they say you kin hear wails and groans deep in th' earth. Mine owner, he sez how it's prolly jus' them beams creakin' under the weight, but it sure don't feel like thet when yer close to by. Sounds like someone's got it out for ya. 
Best you look fer gold in the stream or on one of th' other mountains. Don't get greedy an' go inta the Fellowship Mine.
