Show big increase in utah metal output mines in utah produced gold silver copper lead and zino zinc in 1915 amounting in value to as estimated by V 0 C heikes of the th united states geological survey this represents an increase over the prod product act on in 1914 1014 of nearly 60 50 per cent or thero was a considerable increase in all the metals about one fourth more ore was rained mined increasing tho the total fro from in tons in 1914 to about 10 tons in 1915 1015 about tons were produced at bingham au an increase from tons in 1914 the bulk of this ore wag was mined at the utah and ohio copper properties propel ties wh ch yielded about OF tons of low grade ore in 1915 other mines that contributed large quantities of ore were the utah consolidated utah alej united states bingham bingham new haven and utah metal mines mines the district produced about tons against tons in 1914 the main ore producers were the chief consolidated iron blossom centennial eureka eagle and blue bell mammoth gemini grand central aral and may day mines the ton concentration mill rail built primarily to treat chief consolidated ores did considerable custom work in tho the park city region about tons of crude ore and concentrates were shipped against tons in 1914 improvements in concentration cent ration methods resulted in large shipments of lead aud zino zinc concen from tho the daly judge daly west and silver king coalition mills two large concentration mills were built for treating tailings on tho the flat below park city flotation was adopted at several mills in the legion and the prospect is that all the mills will be similarly equipped in 1916 in beaver county the ore shipments including a considerable quantity of old slag amounted to tons against shipments of tons in 1914 principally from the horn silver and majestic mines in tooele thoele county the ore production principally from stockton and ophir increased from tons to tons in 1915 there were 26 tons hauled from the cotten wood districts to the smelters in 1915 the largest producer wis the cardiff mine which yields rich lead silver ora Import important aut shipments of silver ore were made from the south becia and the michigan utah properties zino ore was shipped from the carbonate mine the mine output of gold increased over 19 per cent from in 1914 to in 1015 1915 copper ores yielded the larger part of the tho gold but large quantities also came from lead ore and siliceous ore A comparatively small quantity of copper ore was produced in gold and silver mills high grade gold ore was mined in the bull valley districts of washington county during part of the year and in the half of the year new developments in the fortana district of beaver county counti attracted attention and wide veins of low grade ore are said to be systematically exploited at the same time small high grade veins of gold ore are ure being mined and milled by lessees the mine production product lon of silver increased from ounces in 1914 to approximately ounces in 1915 the increase ic crease amounting to 14 per cent in quantity and about in value much of the silver is derived from lead ore and smaller quantities from the copper and sili siliceous ceotis ores early in the tho year the knight christensen cn izing casting wasting and leaching mill was destroyed by fire and during the summer was being reconstructed at silver city by the cintia milling co which dismantled a similar plant at park city that was recently used to trait troit ontario ores the new mew plant will probably be in operation birly in 1916 the coppa output from utah mines increased from pounds in 1914 to about pounds in 1915 the increase amounting to more than 20 per cent in quantity and about in value the gain was made mos mostly aly by the utah copper mine at bing ding h im m which is credited with an in crease of pounds over the output of 1914 low grade porphyry ore was produced from the utah copper property and a smaller quantity from the ohio copper mine mine the cactus mine in southern utah was not operated but preparations were being made by a leasing company using tho the flotation process to retreat re treat the cactus tailings which are reported to carry 14 pound pounds of copper per ton the ohio copper mine and mill after going into the hands of a receiver were for a long time idle hub but during the last half of the year were being operated by I loees eisses the mine production of lead in creased from pounds in 1914 to pounds in 1916 or about 28 per cent mostly from f the bingham di district brict where the utah apex utah consolidated unit ed states and bingham new haven were the largest producers in park city the silver kin king coalition daly west daly judge ala au silver king consolidated added to the total out put in the cottonwoods the mines produced over pounds of lead a large part of it coming from the cardiff property with the advance in prices zinc ore was offered from many sources the mine production of zinc recover able as spelter aggregated pounds valued at about this is an increase of about 41 per cent in quantity over the out put of 1914 1014 amounting to pounds the largest shipments of zino zinc concentrates were made from the midvale mill of the united states mining comp company iny which treated some custom ore besides that hauled from its own property at bingham the daly judge mine at park city was the next largest producer of concentrates concentrate 3 followed by the daly west and the mills recovering zino zina from the old tailings lodged on the fiats below park city promontory d district in box elder county became prominent in zinc production from the lake view mine which is credited with pounds of zinc figured as recover recoverable uble spelter new zinc deposits were also opened near hyrum in cache county and woodside in emery county each djs dis brict producing several cars of crude zno ore altogether there were 36 producers of zino zinc ore in utah in 1915 all tho the smelting estable establishments I 1 were operating at full capacity soon after the first of the year these j were the murray midvale international and garfield Garfi Gari old lold plant plants dividends amounting to about were distributed by utah mining companies in 1915 as against in 1014 1914 |
