| Show I Oe W Work I e Ore IRe Reems e I The Tho developments e of tho last year car in the tits Silver King Consolidated 1 mine at nt Park City should be bo comforting to persons who are alarmed alarm ell whenever whenever when when- I ever a well-known well mine hits the back trail lest its like shall never ne be seen n again nin When a n. new ore body equal in size and wealth to anything previously I discovered can bo be found after the conn country tn around has been prospected and mined for fort forty years rears cars there is no r reason ason to doubt that Utah will continue continuo to furnish new bonanzas as long as there is anyone anone here to look took for them Xo Now that tho tiro Silver Kin King Consolidated I has made goo good th tho e geological theory which ed to its development seems so simple that one is is puzzled to account for tho the long dela delay in exploring the tho ground and still more astonished that it remained for S Solon lon Spiro a newcomer in the mining field to put the theory to the test There Is as 35 tI the e work at tho the King Consolidated Silver Sil Kin King Coalition and other Park City mine mines has demonstrated a no stratum of limestone reposing between the shale and the Ontario quartzite which is particularly arly friendly to the solutions in which the metals were carried from rom the deep This limo lime has hns tho the faculty of absorbing the tho metallic particles par par- tides and thereby transmuting itself into ore The Tho existence of the lime stratum was well ell known Imo before the Silver I King Consolidated was org org-an organized but it does docs not seem to have ha occurred I Ito to the tho mining eX experts at that time timo that tho lime be bed extended beyond the tho confines of the tho territory then producing pro oro or that the s system or offis offis- r suns sun's by which the tho ore bearing solutions had hacI gained access to th the more extensive e than it then appeared Spiro had ad no trouble in ascertaining that tho the pitch of the lime bed would take tako it beyond the territory ten in in which it was known known and and although the tIle surface afforded no evidence e of fissuring he he satisfied him himself lf that the vein cin system in the neighborhood was too pronounced to en end abruptly within n tho the limits then assigned to it Tho The absence of surface indications was afterward explained by the discovery that the Ule shale being heing elastic clastic was not fractured b by the forces rh which ch tho the quartzite and lime and tho the fissures therefore were concealed by the o crl overlying ing g shale formation blind formation blind fissures as the miners iners call them Confirmation of Spiros Spiro's theory was ww of great importance to Park Cit City be because it not only the opening o of one of or tho largest t shipping mines of the tho district but pointed the tIle way to other mineral deposits where little prospecting had been heen done but where the soluble lime the mineralizing ng- ng fissures were included include in the geological formation Viewed in this light the tho Silver King Consolidated mine is only tho the first of a series series of ore oro bodies e extending north and west of the old camp of Park Cit City t Visible Ore Supply Trebled i The twelve months mouths since August 1914 1014 are aro in many respects the most important p period rid in the history of the tho King Icing Consolidated The visible ore supply in the tho D mine nc has hns been doubled trebled the surface improve

from fromI t I the he shaft and feet north in in tho bedding None Kone of its dimensions was fully understood The work dono done subsequently ue ly gave o the ore shoot a n. total length of about 1000 feet and the beddings hedding a ran range e of or to 4 O feet A prism of ore oro fully feet long with a 3 width of 40 feet and a a. height of at least 34 feet was demonstrated a n. new oro ore chamber was encountered north Borth of the fissure and evidence e of a n. new ne ore bedding found far to the tho north of the main mam ore channel In the same time the plant has been equipped with a large motor driven compressor a spacious bunk hunk house honse has been erected a gravity water supply obtained and various minor minor improvements carried out Except when storms made hauling impossible ore has been shipped regularly from the nine mine mino to tho the smelter at Murray r the average a. production since sinco January being a about out 1000 tons a month Considerable drifting drifting- has hasen been en dono done on tho the 1800 level and small quantities of ore found in the fissure at that depth g giving ging ing promise of important ore occurrences later on this ancl lower levels I 1 Evidence of tho the Silver Sil King Kinf Consolidated te or ore body was discovers discovered t will ill be remembered in sinking the shaft At a no point 1430 1450 feet from the surface alternate bands of ore and gangue wore were penetrated d for a 11 distance of about 30 fee feet No attempt was made to examine the ore at that time as all haste hasto was being made to complete completo the sinking of the shaft to tho the depth of oC 1800 feet within the time specified by contract As Ls soon as tho the required depth had been n attained work was started on the ore east from the he shaft When a small quantity was taken out the values mines disappeared are Then hen a a. drift was started west from the shaft on the 1500 level 10 Commercial Commer- Commer cial lal ore oro was WM
