pay dirt

As the night was chilly I had brought along an old grey blanket, similar in colour to the mound of the pay-dirt.

Here we have numerous large streams coming down through the mining districts, very large bodies of pay-dirt, and a mild climate.

I heard of one priesk (claim) where the pay-dirt commenced sixty-five feet from the surface.

They were down some forty feet and were drifting in, wheeling the pay-dirt down a series of planks placed on trestles to the dump.
