Gold recovery. Because the gold in the California gravel beds was so richly concentrated, the early forty-niners simply panned for gold in California's rivers and streams, a form of placer mining. However, panning cannot take place on a large scale, and industrious miners and groups of miners graduated to placer mining "cradles" and "rockers" or "long-toms" to process larger volumes of gravel.

Economic Geology Vol. 64,pp. Geology and Geochemistry of the Cortez Gold Deposit, Nevada John D. WmJ.s, L•.•. STO•SER, ^ND J^M•.s E. E•J.•oTx Abstract Gold has been discovered recently at Cortez, Nevada, about 45 miles southwest of Carlin in carbonate rocks in a window of the Roberts Mountains thrust.

The deposits were geochemically similar to other sediment-hosted gold deposits in the Great Basin (e.g., Carlin), but they were uncomplicated by extraneous geologic features such as Paleozoic thrusts or premineralization intrusions.

Thus, the Vantage deposits may be more easily understood examples of this class of ore deposits.
