DEVELOPING THE CROOK CREEK
 GROUP or MINES.
(From Wcunesday's Daily.)

'''' Nt' r''N''r "N''' power, large air compressor, 5000 feet of pipe line, and cquipping his camp for large operations, in ffty.onc days, c. D. F.. Mortimer, general manager of thc Nassau Mining company. operating the Crook group of mines. is pushing development work on that well known and valuable property with an energy unsurpassed in tho history of mining operations in this section.
 On July II he ordered his machinery from the factory in Denver, and despite thc many disappontmcnts due to its Transportation from the railroad term. mus Co the camp over a rugged noun lsin road, with some cf the heaviest grades in the west, hc had it installed and running by steam on August 2s, and operating four power drills in the face of two of his tunnels. on September ., each and every part running in first class shape.
 The Crook group of mines consists of eight patented claims, covering three parallel lodges. known respective groom. Three of the locations follow the Crook vein, which hss record of production of over s250.000. dating back as far as 1875, when the wonder. ful richness of its gold bearing ores at tractcd hundreds of prospcctors to the district from all over the west.
 This mine is opened by cross GU; tunnel. 900 feet in length. which con sccts with n drift following the vein which is closely identif. | with a gran itc and porphyry contact. which can Do traced for great distance across the mountains; this drift is l,056 feet h legnth and taps the vein at one end at depth of 256 feet from its apex. Another cross cut tunnel is now being run to tap this drift at its upper end. when a station will bc cut as soon as the vein is reached, hoisting plant in. N depth. Last month this opening was pushed into the mountain a distance of ll2 feet, and the management ex. poets to encounter the vein l3l feet ahead.
 Tho south shoot of this mine is 360 feet in length. with m average width of about IS inches, some of which has been stopped but large amount of which is still in the mine and ready to be stopped.
 Work is also being pushed in q cross cut tunnel with two power drills. to tap the Premium vein, which is asso. eiated with n granite and schist con. tact, and from surface indications the arrangement expects to encounter the ore body between 500 and 600 feet farther ahead. This vein is opened by one double compartment shaft, sunk to depth of 5d feet, in which tho ore body shows tho entirc width of the shaft, and by another shaft which fol. lows the vein to depth of 60 feet, in which the orc body exposed shows an average thickness of three feet. Tho cross cut tunnel now being run will tap this vein at a depth of 430 fcct from it's apex, inc dip of the vein being in common with the Crook, about 72 degrees to the west, the lodges run. ming north and south.
 Later, operations will be comme need on the Evergreen, which lies in n sim flnr formation to the Crook. and which is equally as promising.
 The location covers water right with a nevcr failing supply of water, sufficient for all demands that mny be u'nde on t for camp or reduction pur. poses, and the mountains in the i'm mediate vicinity arc covered with hcavy growth of pine. from which min. ing timbenr can he had nt n nominal expense.
 The camp is situated in Crook Can. yon. about one-half mile south of the Mount Union Consolidated Mining com. psny's propcrties, and about one mile south of the storm Cloud and Senator mines. all "' which have proven prop. srties of merit. " The preliminary survey for . narrow gauge railroad, tributary and connect. Sng with the Poland branch of tho | Bradshaw Mountain railroad, has al. | ready been made, and it Is believed that tho construction of the line will hc commenced at an carly date.
