Show deschi description ati on of gintic tintic ti antl c standard mine mi e ne BY GEORGE H RYAN in december 1869 the first mining claim in the tintic gintic district the sunbeam was located about two miles east of silver city news of the strike spread rapidly and the nearby hills were soon the scene of active prospecting resulting in the discovery of such surface bonanzas as the mammoth and eureka hill lying in the sedimentary locks forming the high hills to the north locations multiplied rapidly shafts were sunk on smaller and less promising surface showings which sometimes led to ore bodies as great or greater than those found at the surface such as the swansea beck gemini and blue bell the few cabins clustered around or near a mine soon began to have ve the semblance of towns and the district took on the appearance of permanency through the untiring efforts of the pioneers who first prospected the district there grew a permanent camp which has been en a steady producer and which has mining engineer salt lake city added millions to the imperishable wealth of the country after the first excitement died down and a few of the prospects had been developed into shipping mines and

the various mines who had faith in the possibilities of the outlying territory it is to this latter class of pioneers to whom we owe as much if not more for the development of the mining industry the prospector who makes the first find has to face and overcome the hardships nature places in his path to guard against a too easy acquisition of the secrets of her treasury but to the man who overcomes these obstacles in addition to those imposed by man such as unbelief disloyalty refusal to meet obligations and malicious interference or misrepresentation belongs the big credit mark for his perser verance but the best and most appreciated reward in this field of pioneering is the development of a producing mine pioneering of this character has leen been responsible for extending the boundaries of 0 not only tintic gintic but also of nearly every camp in existence not many years ago if one referred to certain prospects me then outlying sections of 0 tintic gintic district a disparaging reply would be given and ridicule directed at the owners especially from members of the old school who were content to rest on the record of past achievement and who do not apply themselves to the solution of the problems presented by the development of the district at the time of the first discoveries in tintic gintic prospectors were giving most of their attention to the igneous rocks hunting for a second comstock and the deposits in the lime stones were not very clearly understood after years of development in the limestone area those who kept their eyes open saw that certain strata were very productive while no amount of work produced any tangible results from the great majority of the strata the ore in these favorable lime beds was found along fissures within or crossing the beds but on oil following these breaks beyond the extremities of the beds the ore soon disappeared even in the ore bearing beds the ore does not make wherever the fissures occur but follows an irregular course doubtless determined by some physical property of the lime not discernible nible to the eye certain characteristics of the soluble lime strata are however apparent to ordinary observation and it is these peculiarities which the observant ones look for when trying to extend the mineralized area some men locate ground without any regard to these fundamental points and then try to swing the known veins to suit their own convenience but to the men who locate ground and develop it guided by disclosures in existing mines and the intelligent study of existing geological data belongs the credit for really constructive and original work impressed with east tintic gintic about ten years ago mr ag R J 0 went into tintic gintic district and after looking over the camp and studying its geology came to the conclusion that the country east from godiva mountain contained potent possibilities some prospecting had been done in that section on small surface showings in the limp lim but a great deal of the country was covered by an extensive flow of rhyolite containing no evidence of and obscuring the greater part of the underlying sediment aries nevertheless from the scant evidence available mr decided that certain ore bearing lime strata should extend out under this east tintic gintic country due to the synclinal structure of the sedimentary rocks composing the main portion of the district formed the tintic gintic standard proceeding on these premises mr secured the nucleolus nu cleous of the pr present besent tintic gintic standard group and during the panic of 1917 interested enough capital to get the enterprise started in addition to beginning operations at a time when the purse strings of investors were pulled tight he has kept going in the face of obstacles which only he knows the magnitude of and how they were surmounted quite recently the word was passed around that the standard had struck it and when the magnitude of the strike became known and the conditions and form of fully demonstrated it was conceded that another pioneer had received the long sought reward which goes to those who persevere along intelligent lines the property of the tintic gintic standard is situated in sections 10 15 16 21 and 22 T 10 S R 2 W S L M east tintic gintic mining district utah county utah geology lying easterly from godiva mountain and gradually dropping away from it to goshen valley the country is composed of 0 low smooth hills devoid of any vegetation but sage for the most part the surface shows only rhyolite with occasional irregular masses of soft yellow porphyry this rhyolite occurs as an extrusive flow and covers a large area in north an and east tin tic where it completely covers the sedimentary rocks except where a prominent peak or ridge stood above the average surface elevation of this flow or where erosion has again exposed the limestone the latter condition exists in the vicinity of the tintic gintic standard where a low hill and ridge of lime protrudes from the surrounding rhyolite the limestone at the tintic gintic standard has all the appearance of what is locally termed the godiva lime so named from the godiva mine which produced its ore from this series which composes the bulk of godiva sioux mountain the sediment aries of tintic gintic district proper lie in what is termed a synclinal fold the western part of which forming eureka ridge exposes the upturned strata in a vertical position but going eastward the strata are found to be more and more inclined toward the east until they lie in a horizontal position about midway between godiva mountain and their most easterly exposure the tintic gintic stand ard lies in the most easterly exposed block of lime where the strata are found dipping toward the west at about 15 degrees development work tile the property is opened by a vertical two compartment shaft 1000 feet deep from the bottom of which a drift was run in a northwesterly direction to cut the downward extension of a fault which the shaft went through at the foot point this fault when cut northwest from the shaft was drifted on for several hundred feet in a northeasterly direction and showed occasional bunches of lead and copper ore the of the fault is quartzite and the hanging wall limestone indicating a normal throw the present working from this level was sunk at a point showing more than heretofore encountered it was put down on the fault to a vertical depth of about feet and showed varying amounts of ore but at tile the bottom ran into a large boulder of gray zinc ore which made about thirty tons of 33 per cent zinc from the bottom of this a drift was run along the fault to the east to a point where a considerable body of low grade ore was encountered some of this ore was broken and treated in two hartz jigs yielding a good grade of concentrate cen no 2 was sunk to a vertical depth of about feet it is on an incline of about 17 degrees apparently following the dip of tile the lime beds and shows more or op I 1 less all the way down bof to where the good grade of ore was en count ered at about the halfway point here a 1 drift was run along the ore which was pen for over feet it was this strike I 1 of shipping ore which caused the sharp rise I 1 in the stock early in the present presen t ye year ar sinking was then continued and the ore followed to the present level from whence a drift was run westerly cutting the present I 1 large in about twenty five feet early in october this was thirty five feet wide east and west seventy feet long and about eight feet high the entire face in north and south ends and back for the entire width is shipping ore and is being broken by only one small machine there are bunches of quartz and lime of varying size as well as occasional bunches of porphyry which are too low grade to ship but the amount of waste may be imagined when it is stated that only one car of waste has been hoisted since early last march the barren material is sorted out on tile the ore platform and does not appear to be more than forty or fifty tons the carlot shipments have have brought from 1000 to each which is ample evidence of the grade of the ore character of ore the ore is characteristic of tintic gintic showing a very large proportion of galena intermixed with bands and irregular masses of shattered siliceous lime and quartz showing some galena and occasionally some copper oxide running through the ore in a north south direction and dipping east at about 80 degrees are seams along which occur irregular cavities and areas of oxidation the banded appearance of the material composing the is very noticeable in places and parallels the seams above mentioned so the conclusion drawn is that these seams represent tile the location of the mineralizing mineral izing fissures lyl which lich not being completely filled have allowed descending surface waters to oxidize small portions of the original even at 1300 feet depth judging from present development it appears that the he has been encountered near its upper extremity at least at this thi s point but this is merely a conjecture which further exploration may prove to be wrong deposits of this nature are very irregular in outline along their strike as has been shown in the other mines of the camp however notwithstanding tile the lack of development so far which makes it impossible to even make an intelligent guess as to the extent of the ore tile the showing is very promising and as lias has been demonstrated st one shift can extract enough ore to more than pay all expenses in connection connect 1 0 11 with sinking the new shaft two shifts working in ore should give the company a 11 nice surplus by the time tile the new work is completed E J manager of the company is very capable and conservative and the stockholders are fortunate in having such a man at the helm up to the time when regular shipments began to he be I 1 sent out the money for development was raised by assessment and a trip over the t property shows that the very smallest amount consistent with the work being done has been spent anywhere but in ill the mine the direct supervision of the work has been under john an able miner of wide experience whose ability is shown by the character of work performed A new shaft with two hoisting compartments is being sunk about 1000 feet northeast of the present one it is already down about seventy five feet which has been done on company account when the gas in present workings prevented operation the gallows frame is up and grading partly done for new buildings and the installation of machinery will commence in a short time sinking the shaft to the 1300 will be done by contract which was to be let on october |
