| Show A sati satisfactory 0 increase in i 0 n utah M metal etal output mines in utah produced gold silver copper lead and zinc in 1915 amounting in value to as estimated by V C heikes of the united states geological survey this represents an increase over the production in 1914 of n nearly early 50 per cent or there was a consid considerable drable increase in all the metals about one fourth more ore was mined increasing the total from tons in 1914 to about tons in 1915 about tons were produced at bingham an increase from 7 tons in 1914 the bulk of this ore was mined at the utah and ohio copper properties which yielded about tons ton of low grade ore in 1915 other mines that contributed large quantities of ore were the utah consolidated utah apex united states bingham bingham new haven and utah metal mines the tintic gintic district pro deuced about tons against tons in 1914 the main ore producers were the chief consolidated iron blossom cen tennial eureka eagle and blue bell mammoth gemini grand central and may day mines the ton concentration mill built primarily to treat chief consolidated ores did considerable custom work production of other districts in the park city region about tons of crude ore and concentrates were shipped against tons in 1914 improvements in ill concentration methods resulted in large shipments of lead and zinc concentrate from the daly judge daly west and silver king coalition mills two large concentration mills were built for treating tailings on the flats below park city flotation was adopted at several mills in the region 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 about tons against ship ments 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 tons of ore hauled from the cottonwood Cotton wod districts to the smelt ers in 1915 the largest producer was the cardiff mine which yields rich lead silver ore important shipments of silver ore were made from the south hecla and the michigan utah properties zinc ore was shipped from the carbonate mine increase in gold output the mine output of gold increased over 19 per cent from in 1914 to 31 3 in 1915 copper ores yielded til the e larger part of the 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 district of washington county during part of the year and in the last half of the year new developments in the fortuna district of beaver county attracted attention and wide veins of low grade gold ore are said to be systematically exploited at the same time small high grade veins of gold ore are being mined and milled by lessees lessels les sees silver shows increase the mine production of silver increased from ounces in 1914 to approximately ounces in 1915 the increase 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 aid siliceous 0 ores res early in the year the night knight K christ ensen roasting and leaching mill was destroyed desi royed by fire and during the summer was being reconstructed at silver GO city by the tintic gintic milling company which dismantled a similar plant at park city that was recently used to treat ontario ores the new plant will probably be in operation early in 1916 copper production heavy the copper 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 mostly by the utah copper mine at bingham which is credited with an increase of pounds over the output of 1914 low grade ore was produced from the utah copper property and a smaller quantity from the ohio copper mine the cactus mine in southern utah was not operated but preparations were being made by a leasing company using the flotation process to retreat re treat the cactus tailings which are reported to carry fourteen 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 but during the last las half of the year were being operated by lessees lessels les sees an increase in lead the mine production of lead increased from 1 pounds in 1914 to pounds in 1915 or about 28 per cent mostly from the bingham district where the utah apex utah consolidated united states and bingham new haven were the ahe largest producers in park city the silver king coalition daly west daly judge and silver king consolidated added to the total output in the cottonwoods Cotton woods the mines produced over pounds of lead a large part of it coming from the cardiff property f increase in zinc production ji wj with t the he advance in prices zinc ore was offered from many sources the mine production of zinc recoverable as spelter aggregated gre gated pounds valued at about this is an all increase of about 41 per cent in quantity over the output of 1914 amounting to pounds the largest shipments of zinc concentrates were made from the midvale mill of the united states mining company which treated some custom ore besides that handled from its own property at bingham the daly judge mine at park city was the next largest producer of concentrates followed by the daly west and the mills recovering zinc from the old tailings lodged on the flats fiats below park city promontory district in box elder county prominent in ill zill zinc production from became

establishments were operating at full capacity soon after the first the murray midvale these were of the year international and garfield plants dividends amounting to about were distributed by utah
