From The Tertiary Channels of Sierra Nevada, California By Charles Lindgren, 1911:

The Ruby Gravel mine, in Sierra County, in which the channel was from 50 to 300 feet in width, was worked for a distance of 3,850 feet and yielded at th~ rate of $465 a linear foot. The cost is stated to ,have averaged $240 a foot.

For comparison it may be mentioned that according to A. H. Brooks the average value of the principal creeks at Nome, Alaska, is approximately $100 a foot. The White channel in the Klondike yielded $380 a foot. In the Berry drift mines in Victoria, Australia, the yield per foot ranged from $440 to $1,293, the width of gravel mined being from 330 to 1,000 feet.
