YUCCA TUNGSTEN
 ONE OF GREATEST
 PRODUCERS INu,S.
There Are Few If Any Mines Producing More Tungsten In the U. S. a Carload Con- centrates Running $40,0OO Shipped Every 35 Days

One of the greatest tungsten mines
 in the world is located in Mohave
 county. Would you believe it? It
 is the property of the Yucca Tung-
 sten company and has been operated
 quietly the past three years, at first
 in a small way, but now with a force
 of from 40 to 50 men. It started out
 with the opening of the mines by
 short tunnel that reached into the
 vein and then along the vein several
 hundred feet. As soon as the ore
 was opened sufficiently td know that
 sufficient ore was in sight to main-
 tain small mill, crushing plant
 and several hand jigs were installed.
 The management was placed in the
 hands of Harvey Klotsch, who is still
 at the head of the company's affairs.
 Within the year, after the installa-
 tion of the little mill, more than $100,- 900 worth of tungsten was shipped to the buyers and another tunnel run into the vein at lower level. Dur
 ing the year estimates were made and | a new mill designed. This mill, with | an auxiliary power plant has been
 built and is in commission. It has a
 capacity of 60 tons of ore daily and is
 being run to full capacity. It is turn
 ing out carload of tungsten concen-
 trates monthly ranging from 65 to
 Fl per cent tungstic acid and valued
 at better than $4O,00O per car. A res
 idue is being piled up that carries values of about per cent tungsten
 and to 8 per cent copper that will later be treated by oil Notation, the copper being extracted and the tung-
 sten later being saved on slime table. In this way the saving of tungsten will be increased many tons monthly and carload of copper concentrates also being obtained. The copper will pay the greater part of the cost of operating the mine and mill.
 The Yucca Tungsten property is $ situated about 16 miles easterly from Yucca, Tn what is known as the Cop , per World country. Its holdings em- brace large acreage of mineralized f ground, although only a small part { of its land has been actively developed. Three tunnels have been run into the { main vein, which is opened to a depth i of several hundred feet. The lower , tunnel is ip 500 feet on the vein and $ from the level a shaft has been sunk 100 feet in the ore. Levels have been carried off from the bottom of the shaft in splendid ore. The opening of the ore body at this level estab- lished its permanency and richness. The vein has good width and can be depended upon td furnish ore enough for the larger milling plant that is |, being designed. K
 Tests are now being carried on for u he purpose of installing an oil flo- T ,ation plant to handle the tails from ri he jigs and tables, and if successful st he new plant will soon be in commits bt ion. al
 All shipments of concentrates are th lnder government license, the gov le rhment taking over the entire pro- uee ef the mine. These shipments in re made to the York Metal and AL ce oy comr airy, of York, Pa., which is bu aid to be one of the largest users of te lngsten in the world. The company dc , also large shareholder in the Yuc- m a Tungsten and have needs of great a r production, which would indicate lie nat a bigger mill and more miners du ill necessarily follow the demand. mi The Yucca Tungsten is producing mi ne of the most important metals nat our work demands and nothing M nould stand in the way of aiding the MI 'mpary in maintaining its production. , is right now under the orders of ,e government and every pound of
 etal it produces goes into the hands the firms manufacturing govern
 ent supplies. lnt I'll lllIl Tnn nTlllN nm ret
