Show MONTANA production IN 1912 the value of the mine production of gold silver copper lead and zinc by montana in 1912 according a cc to V C heikes of the unit ed states geological survey was against in 1911 an increase of due to the greater production and higher value of copper the value of the silver copper and lead combined was more than in 1911 while the value of the gold aud and zinc was less than in 1911 the value of the production of silver dow bow county which includes the butte district was over 93 per cent of the total value of the metals from montana in 1912 the increase in value in this county was so that the combined production of the other counties in montana was only greater in 1912 than in 1911 the production of gold in 1912 was valued at against in 1911 over 56 per cent of the gold or ounces was derived from sili siliceous clous ores 39 ounces or per cent from placers and ounces or per cent from copper ores the placer gold in 1912 amounted to of which was obtained by dredging tha gold won from pacers in 1912 was more than in 1911 and that taken from the lode mines was the gold recovered from ore treated at gold and silver mills amounted to that from concentrates amounted to and that from crude ores shipped to smelters shelters sm elters the production of silver in montana in 1912 was vas ounces valued at against ounces in 1911 nevada vill likely lead in silver output in 1912 followed by utah and then by montana of 1912 output of silver ounces or per cent came from copper ores and ounces or about 10 per cent from cious ous ores bullion recovered at gold and silver mills produced only ounces while concentrates produced cances and crude ore shipped to amel contained ounces silver bow county produced ounces or 89 per cent of the states production compared with an output of ounces in 1911 the production of copper in montana increased from pounds in 1911 to pounds valued at in 1912 a gain of pounds the summit valley or butte district contributed all but pounds of the total the production of lead in montana increased from pounds in 1911 to pounds valued at in 1912 neary nearly all the metal mining counties in montana made a small bied of lead but cascade jefferson lincoln and silver dow bow counties with a production of pounds in 1912 against 0 pounds in 1911 produced 84 per cent of the output for the state of montana in 1912 and 74 per cent of the output in 1911 zinc output in 1912 reported as spelter aggregated pounds valued at against pounds in 1911 the summit valley district in silver boy county yielded all the sulphide concentrates containing pounds of spelter and jefferson lincoln and fergus counties produced pounds the contents of sulphide and carbonate ore shipped direct to eastern reduction works the number of deep mines producing metals in montana in 1912 was against in 1911 and the number of producing placer mines was against the total quantity of ore sold or treated was tons and the total average recoverable value per ton toil of ore produced increased from in 1911 t o Q 1152 in 1912 0 |
