Plant Operating Near Susanville
April 20, 1941
Fifteen hard-rock miners are employed at the new $20,000 plant of the Diamond Mountain Mine and Milling Co., which started a little over a week ago for the season.
The mill is operating for the first time since construction, with A. G. Lantz, a San Jose contractor, and Ralph Fitzpatrick, Petaluma business man, the sole owners. R. S. Barthoff, formerly of Quincy, is the superintendent in charge.
The new plant includes a ball mill with flotation equipment for the recovery of gold lost in the first milling process.
Work is in the primary stage as samples are being taken every half hour from the new ore and tailing to determine the rate of the metal production per ton. Up to the present time the re has produced about $6 per ton, but it is expected that more can be saved as the process is changed to meet metallurgical requirements.
The plant, which is on the George N. McDow Jr. property six miles north of Susanville, is equipped with a modern assay plant. Power is furnished by the rural electrification administration.
