Future of Gold Mining As
 Seen By Experus

I lower but other metals have taken
 their place.
 The ores of the Rocky mountains
 steadily increase in the percentage
 of zinc as depth is obtained. In the
 mines of Utah and Colorado almost
 incalculable tonnages of ore can be
 produced containing about 20 per
 cent zinc, per cent lead, per
 cent copper and s4 or s5 a ton in | gold and silver. This ore is in 1 tTinsically worth $40 ton, yet under
 present conditions the miner win be fortunate if he realizes from s to
 ss after giving the ore a treatment by concentration. The concentra- ton losses on this ore is exceed ingly heavy, and it is questionable if any of the new processes of con
 centration can be satisfactorily ap-
 piled. In a few camps, under favor able conditions, this ore can be handled to a certain extent and some of it is being mined at a great sac rifce. However, in by far the great CT number of camps such ore can not be touched. and this forms one of the great potential reserves of the future. When this problem is solved, then the ore, no longer re fractory. will yield enormous quan- titles of gold and silver
 The older mining districts are steadily yielding large outputs of precious metals. It can by no means be said that the surface workings of the great older mining camps have yet been exhausted and as witness es to this there may be recalled the recent discoveries in Leadville and Cripple Creek Great discoveries may be looked for even in the older
 mining districts at comparatively shallow depths, and we may there fore confidently rely on the old CT mining districts to maintain their precious-metal production for years to come.
 In relation to the discovery of new gold and silver districts, it is certain that the next few years will
 witness great discoveries in the west. Idaho, Montana and Oregon have tremendous reserves of gold and silver ores simply awaiting cap itaI and metallurgical skill How ever. there are certain regions which owing to the activity of the pros pector, bid fair to open up new and possibly bonanza districts at an early date. Psrticuar reference is made to eastern Nevada along the state line separating it from Utah; eastern and western banks of the Colorado river, and lastly the really wonderful discoveries made in the La Plato district in south western Colorado.
 So, instead of the outlook for the production of precious metals being discouraging. there is TO period with in the Last 10 years when 1t was more encouraging than at this time If the same energy were displayed in the opening up of gold and silver ores which is displayed in the min ing of copper the gold production of this country would be nearly doubled. and an output of at least $50 DOG. 900 per annum could be maintained for many years to come. In order that these possibilities can be realized, however, there can De no question but that the business methods Of gold mining companies must be entirely reorganized. The lack of confidence on the part or the investor in gold and silver min ing must be replaced by an assur- ance uhat he is at least going to have a run for his money.
 The Mining World is of the opin- ion that there need be no alarm over the prospective production of gold and silver for the next few generations at least.
