Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1911 edition. Excerpt: ...The gold output of the State increased only slightly, from 69,827.33 ounces in 1908 to 70,328.64 ounces in 1909. It was a good Tear in both placer and quartz operations, although gold production from Elacers decreased slightly. There were considerable increases in emhi, Elmore, Blame, Owyhee, Boise, and Shoshone counties, but a decrease of $190,678 in Custer County alone nearly offset the combined increases. This is accounted for by the unproductiveness of the Lost Packer mine and the reduced output of the Golden Sunbeam mine. Gold production from placers amounted to $281,727, or 19.38 per cent of the total output; and gold from siliceous ore increased to $1,08.8,052, or 74.84 per cent. The idleness of the Lost Packer smelter was also the reason for the gold production from copper ore decreasing to $24,398, or less than 2 per cent of the total. Lead ore furnished over 4 per cent, or $59,201. Next to the Silver City region, in Owyhee County, which produced nearly 30 per cent of the gold, Boise, Idaho, Elmore, Lemhi, Custer, and Shoshone counties came in order of importance. There were 189 placer properties producing, of which 178 were worked by the hydraulic or the sluicing method, producing $177,164; three by drift mining, producing $2,859; and eignt by dredges, producing $101,704. Dredging produced a considerable increase in 1909. Snake River, from nine counties through which it flows, yielded $8,690 in gold and 32 ounces of silver. Crude ore shipped supplied $50,404 of gold, or 35 cents per ton, and concentrates, $267,202, or $1.41 per ton. This amount is divided into $197,502 from concentrates from gold and silver mills and $69,700 from lead concentrates. The former averaged $93.64 per ton and the latter 37 cents per ton.
