GOLD AND SILVER.
171
Ore treated, and value of gold, silver, copper, and lead recovered in 1904, by counties.
[Short tons.]
Average value per ton: Ore milled. $5.07; ore smelted, $16.88.
In the preceding table the averages of the smelting ores are also given. Inyo has both lead and silver to its credit. In all the other counties the copper ores are considered, and also the gold and silver derived from the smelting of these ores. The most extensive operations are shown to be in Shasta County. It has been found somewhat difficult to get at exact data concerning the lead ores, most of the ores shipped being small lots and from mines worked intermittently.
