Show oregon metal production products on in in 1 1916 9 16 preliminary estimates of the production of metals from oregon mines in 1916 by the united states geological survey department of the interior show increases over 1915 for gold silver and copper and a decrease for lead the output of gold in 1915 was and the estimated output for 1916 is an increase of the output of silver in 1915 was ounces and the estimated output in 1916 is ounces or ounces more the output of copper in 1915 was pounds and the estimated output in 1916 6 is pounds an increase for 1916 of pounds and the output of lead in 1915 was pounds as compared with pounds in 1916 or pounds less these preliminary figures are compiled by charles G yale of the san francisco office of the geological survey the increase in gold is merely nominal but that of silver has about doubled the most notable increase is in the quantity of copper an increase caused by the incentive offered by high prices output comes from deep mines there are less than a hundred productive metal mines in oregon and the number ot of placers is about double that of the deep mines however two thirds of the gold output and virtually all that of the other metals is derived from deep mines no very productive now new properties have been opened during the year the entire output of the deep mines is derived from less than tons of ore having an average value of about 9 a ton baker is still the most productive county in the state yielding annually nearly 90 per cent of all the gold the cornucopia and the baker mines in the cornucopia district baker county are the most productive deep mines minea in oregon other large deep mines in baker county are those of the commercial mining company rainbow mine at rye valley in the mormon basin district or the columbia gold mines company at sumpter cracker creek district and of the homestead iron dyke property at copperfield iron dyke district dredges operating the powder river dredge company operating two dredges near sumpter cracker creek district is the most productive placer mining enterprise in ill the state in 1916 a new dredge was under 0 construction O st in the john day valley grant county the most productive hydraulic mine in oregon is that on the property of the columbia mines company in placer district josephine county other notably productive hydraulic mines are the martin daniels galice district josephine county and the sterling in forest creek district jackson county the gold won by dredging aar exceeds that obtained by all other forms of placer mining combined bombin ed |
