Show MINING IN MONTANA IN 1919 the value of the gold silver copper lead and zinc mined in montana in 1919 according to the estimate of C N gerry of the united states geological survey department of the interior was more than a decrease of about as compared with the value for 1918 all the metals but lead showed a decided decrease on account of the low prices for copper lead and zinc the mines of butte soon after the first of the year reduced their output to about 60 per cent of the normal production from the mines was not seriously affected by strikes though there was some labor trouble in february value of gold output the value of the gold output fell from in 1918 to about in 1919 a decrease of nearly 27 per cent the main decrease was the output of gold derived from copper ores there were slight decreases of gold derived from iron ore siliceous ore and from dredging the barnes king mining company operating in fergus and lewis and dark clark counties produced the most gold from siliceous ores the southern cross mine in deer lodge county produced much less gold mine output of silver the mine output of silver decreased from ounces in 1918 to about ounces in 1919 and the value of the output decreased from to about in 1918 and 1919 montana was the leading silver producer of the united states in 1919 as in past years most of this silver came from copper ores but a large part of the increase consisted of residues from zinc ores both those smelted smelter in the east and those treated in the electrolytic tro plant at great falls mont the principal producers of silver were the anaconda copper mining company butte superior elm orlu north butte east butte davis daly butte reduction works tailing dump and the gran granite I 1 te bimetallic 1 c mine at philipsburg copper output decreased the output of copper decreased from pounds in 1918 to about pounds in 1919 this represents a decrease of pounds in quantity and in value the average monthly production of the smelting smelling sm elting plants in the anaconda copper company at great falls and anaconda according to published statements was nearly pounds of copper as against pounds in 1918 the Pitts mont plant of the east butte company produced more than pounds a month instead of 2000 pounds as in 1918 in addition to the mines of the anaconda and east butte companies the north butte davis daly butte reduction works dump butte rams dall elm orlu butte duluth butte superior tuolumne and produced considerable copper decrease in lead the mine production of lead increased from pounds in 1918 to about pounds in 1919 but the value of the output decreased from to about A large part of the lead was obtained from the lead z zinc inc ores of the butte district the snow storm mine giue at troy lincoln county and the angelica mine in jefferson county were also notable contributors products byproducts by from the electrolytic zinc plant at great falls have added greatly to the totals of both silver and lead the lead smelter of the american smelting smelling Sm elting refining company at east helena was active on ores and concentrates most of them shipped from idaho and montana recoverable zinc the output of recoverable zinc in montana decreased from pounds in 1918 to about pounds in 1919 the value of the output decreased from to about the principal zinc producers of montana were the butte superior anaconda elm orlu and butte copper zinc mines smaller producers were the snow storm mine in lincoln county the davis daly at butte and the montana consolidated in jefferson county most of the zinc concentrate was smelted smelter in the east but zinc ore from the mines of the anaconda copper mining company was concentrated at anaconda and the concentrates were leached beached at great falls the electrolytic plant was active during 1919 but the output was less than that of 1918 when much custom m material a was treated the dividends paid by montana companies for the first eleven months of 1919 amounted to about the principal dividend payers were the anaconda copper mining company and the barnes king mining company |
