A great tunnel enterprise for gintictintictiantic mining distrBY WILL C HIGGINS

A martin and associates of salt lakeare actively engaged at the presentin formulating and perfecting the deof an enterprise that is gigantic in

magnitude and which should add manyss to the life and productiveness of theses of tinticgintic district utah and at the

ee time provide means for economicalationation to say nothing of the added revss totb be derived from milling opera

electric power plants and irrigationositions

doubt could be made to produce many mil-lions were they susceptible of economic op-eration to depths of 1500 to feetas it has been demonstrated that their orezones extend below the water level withevery indication that they will maintaintheir size and value to great depths

for years it has been the dream of tintic mining operators to secure drainage fortheir holdings latat depth to say nothing oftransportation facilities that would obviateexpensive hoisting and an outlet for the

brict and this is especially true whermining in the district is concerned

the propositionwhen rounded into shape the ente

in question will be known as the tintigintinel company

this company according to prelimplans proposes to start taia large dratransportation tunnel near thothe hegoshen valley on the foot c
