d Director of the Mint for 1881, p. 435, under Summit County, says: "On Eagle
River, at Red Cliff, the Belden Mining Company and the Battle Mountain smelter
have produced a large quantity of base bullion. . . . No ore is being snipped
except from the Belden Company's mine, and from this but four car-loads per
day. The ore, containing as it does a large percentage of lead, forms an excellent
flux for the dry ores and will aid materially in smelting. In Gold Park, near the
Mount of the Holy Cross, a considerable camp has been established, and a large
stamp-mill erected to crush the gold ores found there. The veins are quite strong,
the quartz at the surface to a depth of 12 under to 15 Summit feet, much County, decomposed, says, "At and Red
the
yield $10 to $25 per ton under stamps. Below the decomposition the ores are mainly
white iron pyrites. This section is scarcely more than a year old "
