Show A Prosperous Year in the Mines of the Rocky Mountains. Tho metnl mines of tho Ilocky Maintain Statpg havo had a year of activity in many respects never bo fo:c equaled. The preliminary h,n-tittles h,n-tittles of production reported from tho Denver nnd Salt Lake City cilices cilic-es of tho United States Geo oglcal Survey lndlcnto n marked Increaso In tho output of each State over tho production of 1911. While tho tonnage ton-nage of ore mined wns generally greater, tho largo increase In total nines was even juoro the rosult of higher prices for tho metals. This Increaso In valuo of output over the corresponding flgmos for 1014 leached leach-ed SI per cent for Montana and. CO per cent for Now Mexico. Tho total to-tal of theso notable lncrcnres tor the six states la estimated at more than $115,000,000. 1915 was Montana's best as measured meas-ured by total ' voluo of initio output of the metals. Thcro was an increase in-crease in tho mining of nil the met-nln, met-nln, but especially of lead and zinc. Even of sllcr tho output of about 1-1,500,000 ounces wns a record breaker, break-er, being duo not only to tho enlarged enlarg-ed output of copper ore which s-ip-t lied the greater part of tho silver, but tho great Impetus given to tho marketing of zinc ores. Tho mines output of gold was valued at nearly $5,000,000 an Increase of more than 20 per cent over 1914. Montana's grenteiit asset is copper, tho output of which Increased from 233,22'J,C10 pounds In 1914 to nearly 27f.,000,O00 rounds in 1915. Tho mine output of lend increased to over 11,000,000 pounds In 1913, an increaso of over 1." per cent, duo larg' to tho shipment ship-ment of load concentrates and of residues resulting from zinc molting. molt-ing. Zinc Increased from U1,'50,5I4 pounds figured as spelter) In 7914 to 184.0SC.O0O pounds In 1915. Tho total va'uo of tho flvo metals from Montana mines In 1915 was nc-nrly JS7.000.000. Utah Shows 10 Million Increase In I'toh tho mines output figures showed u vnluo of $35,000,000 representing repre-senting nn Increase over tho produc tlun in 1914 in nil the metals if nenr ly 50 per cent or JlS.000,000. About ciio fourth more oro wns mined, In-crcariug In-crcariug the total from S,o44,Oi4 tons In 1 It to 10.725,000 tons In 1915. T; r. iilru- input of gold Increased to $3,9t8,oiio or over 19 per cent. Copper Cop-per ores yielded the greater part of tho gold, but largo quantities nlso en mo from lead oro nnd siliceous cru Tho mine output of silver increased to 12, 724,000 ounces, an Incrruiio of 14 per petit In quantity nnd $109,000 In value. Tho copper output Increased Increas-ed from 152,031,002 pounds In 1SU to about 1S2.5S9.000 pounds In 1915 -20 per cent In qunntlty nnd $li,-450,000 $li,-450,000 in vauo. With tho advance In prices, zinc oro was ofTciod from many sources. The mlno production of zinc recnvorablo as spelter aggie gated 22,043,000 pounds, vahii-.l at J3-224,000. J3-224,000. Ovr 50 Per Cent Increase For Idaho The vnluo of tho increase In output of metals In Idaho was over 53 per cent, with n total production of 5.17,-TSO.tno. 5.17,-TSO.tno. The gold production vos nearly tho samo In 1914, silver Increased In-creased nbout 4 per cent In qnuntlO .rtliouuh It decreased In vnluo. C'r-per C'r-per Increased from . J4j 1ST I'ounds lu 1914 to 7,109,000 pounds In 1915 Tho great increase In the total value or Idaho's metal output, nmounMtig to moro than $13,000,000 was duo ory largely to tho Increased prlco of b-nd and -lnc. Tho production of lead vnf 'I77.0no.o00 pounds, nn increaso of 8 per cent nnd tho valno of the out put was nearly $1,000,000.
