- Yeah, it's mighty rich. It'll pay good.
- How good?
- Oh, about 20 ounce to the ton.
- That's some $20 an ounce.

Quote context

[...]

- Yeah, don't expect to find nuggets of molten gold. It's rich, but not that rich. And here ain't the place to dig. It comes from someplace further up.

- Up there. Up there's where we got to go. Up there!

- Is that it?

- That's it, all right.

- The gold, I mean.

- It sure don't look like I thought it would.

- It's not much different than sand.

- Yeah, it's just like plain sand.

- It don't glitter. I thought it would glitter.

- Oh, it'll glitter when it's refined. That's some other guy's job. All we got to do is mine it and get it back there.

- You know, gold ain't like stones in a river bed. It don't cry out to be picked up. You got to know how to recognize it. And finding it ain't all... not by a long shot. You got to know how to tickle it so she'll come out laughing.

- Yeah, it's mighty rich. It'll pay good.

- How good?

- Oh, about 20 ounce to the ton.

- That's some $20 an ounce.

- How many tons can we handle a week? Depends on how hard we work.

- We'd better pitch our camp down the mountainside a bit.

- Why do that when the digging's up here?

- In case anybody happens by, we can tell them we're hunters and get away with it, maybe.

- Wouldn't it be easier to file a claim?

- Easier maybe, but not so profitable.

- Wouldn't be no time till a man from one of those big mining companies would be up here with a paper in his hand showing we had no right to be here.
