CENTRAL Mining District JAMESTOWN, Boulder County. - - ;.ORArx). A Concise Description of the Mines of This Disti^ict, WITH A Detailed Account of Each ov tui: More Valuable Properties. CliMPILEU BY U * THHATaXc; y^, NOIWn % DENVER: Times Printing House, i83a University of California • Berkeley Central Mining District. To THE Public: The miners of Central District, Boulder County, Col- orado, would respectfully ask your careful perusal of this pamphlet, guaranteeing it will repay ' c;^ for so doing, by — if you are interested in viewing Rotky Mountain scenery — informing you of the cheapest and shortest route from Denver to witness it in detail; or, should you be interested in the subject of mining, showing you properties of grerter or less value, and opportunities of legitimate investnl&nt unequalled in the State. The citizens of our district are all acting in harmony for honest realizations, and the visitor may be assured he will not be annoyed or harassed by mining sharks. However, should he come as tourist, in- vestor or emigrant, he is assured a hearty welcome. The following are a few of the advantages of the district : 1. The district produces the richest gold and silver ore found in the world ; ores worth as high as ;^200,ooo per ton. 2. The veins are true fissures, producing all the dif- ferent varieties of gold and silver ores, free milling, smelt- ing and concentrating, carrying gold, silver, iron, copper and lead. ,. 3. The district lies nearer to Denver than any other mining district, a pleasant ride by rail and carriage of only four hours, bringing the visitor to the heart of the mining settlement. [2] 4- The district is accessible at all times of the year, and mining can be prosecuted during the winter months even with more advantages than during the summer. 5. As a place of residence, no mountain district could surpass. Water power and timber for mining purposes is abundant, and smelting works have been in successful op- eration within from six to fifteen miles of the mines for the last seven years. DIRECTIONS. Jamestown and Springdale are the principal mining camps of the district. To visit either, the tourist should take the train of the Colorado Central jc-ylroad, ieaving the Union Depot at Denver at 7:10 a. m. 'bV, 8 p. m., purchasing ticket for Boul- der, which is reached after a pleasant ride of two and one half hours. Boulder is a neat, pretty city of about 5,000 inhabitants, the majority of the citizens being cultured and Jt^ refined, of considerable wealth, and mostly former residents ^''^' of eastern cities. The city is situated at the mouth of Boulder Canon, one of the noted entrances to the mountains. At Boulder is situated the State University of Colo- rado, and the public schools are noted for their efficient management and high grade of instruction. The fare from Denver to Boulder, regular rates, is ^2.30, but will probably be reduced during the Exposition. At Boulder the tourist can take stage to Springdale and Jamestown, or, should he prefer, can hire at any livery stable in Boulder a good buggy and safe mountain team for a period of twenty-four hours at a cost of ^5. Leaving Boulder, he enters the foot-hills, and over a well graded road trots to the summit, where he is surprised by a grand view of the plains, looking like a vast sea spread at his feet, with the town of Longmont, fifteen miles distant, appearing as only five miles away. Hardly [3] noticing the change, he has entered the canon, and the roar of Left Hand creek suddenly causes him to realize that he is hemmed in by mountains on either hand. A ride of three-quarters of an hour brings him to Springdale, where he finds a commodious hotel and the famous Seltzer Springs. These springs alone will repay him for his visit, they resembling so closely the Seltzer Springs of Germany that experts have been unable to de- tect by taste the one from the other. For dyspeptics, the water of these springs will generally effect a perfect cure, unless the patient has a complication of other diseases. For rheumatism the same can be said, the only difference in treatment being that the wa£er is applied in the shape of warm baths. Good simple board c .:*4be obtained here at ;$io per week, or for transient $2.^(^ per day. Here are situated some of the famous telluride mines. One and one half miles above is Jamestown, the prin- cipal town of the district. Jamestown is situated on a flat about one half mile in width, surrounded by the mountains. It is a town of about 200 inhabitants, containing three general stores, post office, one blacksmith shop, one hotel, two saloons, one mining brokerage office, one assay office, one saw mill, and one church. It also contains one con- centrating mill, operating Frue Vanners, one roasting and amalgamating mill, capable of treating twenty tons of ore per day, and two mills operating the Robinson process, each with a capacity of twenty-four tons per day. There are also two free gold mills ; one, the Golden Age, operating twenty-five stamps, the other operating but six. The town has just agreed to sell to the Crocker Pro- cess and Reduction Company a mill site on which they in- tend to erect one of the largest works in the county. James Creek, a fine stream of pure mountain water, flows directly through the town, and the water it affords is [4] sufficient to run a dozen or more mills, besides supplying all necessary for town purposes. The town is noted for its absence from drunken brawls, gambling and other ordinary evils of mining camps, the citizens having come to stay, and their time being fully oc- cupied in the development of their mining properties. The mail now leaves tri-weekly, the stage, however, running to Boulder and back daily. The citizens have petitioned for a daily mail and expect it will be ordered carried by August 15th. The climate is moderate, sojourn- ers not suffering extreme heat during the summer months, or intense cold during the winter, snow seldom lying on the ground over foi;ty-eight1iours. The mines mentioned in this pamphlet all lie within a radius of five miles of Jamestown. A number of locations we are unable to mention, the ores and information having arrived too late. Of these are the Last Chance lode. Bond- holder, Overland, Big Lead, and others. In conclusion, we would repeat our invitation to the reader, rich or poor, to visit our camp, and we will take great pleasure in showing him our home and surroundings, and leave him to his own judgment regarding the merits of the camp, knowing that in all events his trip will be a pleasure and give him a better idea of mountains and mines than could be obtained by a trip to other sections occupying twice the time. Respectfully submitting the foregoing to your kind consideration, and commending the following description of the mines, I am respectfully Your Obedient Servant, Thos. H. Noland, Representative of Central Mining District, of Boulder County, Colorado. By order of Executive Committee. [5] THE GOLDEN AGE 'Was discovered a few years since by " Indian Jack, who with others interested with him sold it to H. P. Walker & Co. shortly after its discovery. These gentlemen at once set about developing it, and erected a shaft house and a ten- stamp mill to treat its ore, which was afterwards increased to fifteen stamps and later to twenty-five stamps, which is the present capacity of the mill. In May, 1879, Messrs. Walker & Co. sold to Mr. Eu- gene S. Pike and the Parnely Bros., of Chicago, for a large sum, when hoisting machinery was placed in the shaft house consisting of a twenty-five horse-power engine with friction hoist. The shaft house is a good substantial frame, 40 x 70. When Messrs. Pike & Parnely too;: possession it had for workings one main shaft which haci attained a depth of 230 feet with two sets of levels running each way from shaft, two at a depth of about 100 feet, the others some 85 feet deeper. They have since, under the management of D. H. Pike, at a depth of 228 feet, run a third level, the total length of all levels being 710 feet. The third level was run west for a distance of twenty feet and from the break a cross cut was run thirty feet to cut the foot wall along which a level has been run west for a distance of sixty feet and has been connected with the second level by means of a winze. There has also been a cross cut of forty feet made in the second level east, fifteen feet distant from the shaft, cut- ting the foot wall, and along which a lOO foot level has been run. Beside these workings there has been a large amount of prospecting along the vein on the surface. The main shaft is heavily and substantially timbered, with car track, ladder ways, and good flats at each level. They are now working a force of twelve men including teamster. The work of the past year has been almost exclusively [6] confined to the foot wall pay chute and has been largely in the development line, there having been only a little over 2,000 square feet of stoping done. The yield of ore from the period from the middle of May last year to the same time this year has been a little over 360 tons ; the yield in bullion for the same time being between forty-one and forty-two thousand dollars ; and this with the labor of but five men, and at a total expense for mining, milling, repairing teaming, and all incidental ex- penses of less than ;^ 12,000. The amount of ore in sight in the workings has been largely increased during the year, and with the increase of labor promises a latger production for the present year than for any like period since the discovery of the mine. The ordinary milling ore, of which there is two feet, yields on an average ;^20.00 per ton under stamps. The ore showing metallic gold appears at intervals in all parts of the mine, running in a streak by itself at times, and at others appearing in the midst of the lowest grade ; and although appearing at intervals the average monthly yield is the same. This ore is placed by itself and treated by hand in a mortar. The following are the results of some of the later work : 100 lbs ore gave net - - - - $ 896. 13 74 " " " " 2,611.65 270 "'♦•'" .... 5,029,64 325 " '• " " 6,302.69 Fifty pounds ore shipped last week gave a retort valued at ^2,650.00, or over ;^52.oo to the pound of ore. The mine is situated on Golden Age Mountain at an elevation of some 8,000 fee^, and where work can be prose- cuted the year round. There is an abundance of timber in its immediate vicinity, with good roads connecting with all points, and is convenient to supplies: From the shaft house of this property the view of the snow covered mountains and the plains stretching away in the distance is not exceeded in any part of the state, and on any clear day the outlines of the streets of Denver, forty miles distant, are plainly visible to the naked eye. The proximate yield of bullion as shown by the books of the National Banks at Boulder since the discovery of this property is ;$ioo,ooo; and placing a low estimate on the receipts to others from all sources for ore from this mine, say ;^30,ooo, would make a total receipt of 1^130,000. THE ARGO LODE Is situated about three-quarters of a mile west of Jamestown and is owned by E. L. Hubbard, of Cimarron, New Mexico. It has been developed by a shaft forty-five feet in depth and some small su^rfa-'c openings. The char- acter of the ore is galena carrying iron and copper. It has a crevice averaging eight feet in width, the pay streak varying from four to six feet in width. The owner being absent and the property^idle, no further information could be obtained. THE AMERICAN LODE Is situated one mile north-west of Jamestown in Elk Horn Gulch, and is owned by Geo. W. Reardon, of James- town. Its development is a tunnel 150 feet in length and two shafts, one sixty feet, the other fifty feet in depth, all the workings showing good ore. The crevice varies from five to eight feet in width and carries a large body of free gold ore, the first class assorted giving returns of from ;^icx).oo to ;^320.oo per ton, the large body or second class giving from ^20.00 to ;^40.oo per ton. BUCKEYE LODE Is situated north-east of Jamestown, about one half a mile west of the Golden* Age. [«] It is owned by W. T. Turner, of Jamestown, and is de- veloped by a shaft twenty feet in depth showing a crevice of four feet enclosed by good porphyry and granite walls. The character of the ore is free gold and is easily heated over coppers, a good deal of the quartz showing to the naked eye the metallic gold. Returns from the ore have been as follows: first class, 1^8040 per ton; second class, ;^40.oo to ;^5o.oo. THE BUENOS AYRES LODE, Owned by John M. Williams & Co., is situated a short distance west of Jamestown. It has been developed by a main shaft seventy-five feet in depth, and with a c^foss cut tunnel which is now in some seventy-five feet, and which when completed is to cut the vein 100 feet deep. The crevice, between good, strong granite walls, is three feet, with a pay streak of eighteen inches. The character of the ore is fluor spar impregnated with iron pyrites, galena and copper, and has an average value of from ;^40.oo to ;^ 150.00 per ton, while selected pieces will run ^300.00 per ton. When Mr. Boyd was operating his smelter at Boulder City he purchased this ore, giving special prices for it on account of its valuable fluxing qualities. THE BIG THING (BUCK HORN) Is located about one-half mile west of Jamestown near the main road, and is owned by A. Arnett & Co., of Boul- der. It has for developments one main shaft, 80 feet in depth with some little drifting. The character of the ore is fluor spar carrying galena and iron from which shipments have been made ranging from ;^40.oo to ^80.00 per ton, with allowance made for fluor spar on account of its valuable qualities as a flux. The mine is now lying idle on account [9] of lack of machinery to keep the workings free from water. THE BLUE JAY Is located a quarter of a mile from Jamestown and is owned by Geo. W. Reardon. It has for developments one 12 foot shaft, which shows a large body of fluor spar from ten to twelve feet in width, which carries about ;$ii.oo in silver per ton and a small per cent of copper and galena. Its principal value is in the fact that it is used as a flux in smelting other ores. There are five other leads forming a group. THE BALD EAGLE Is situated about seven miles north-west of Jamestown on the St. Vrain. It is owned by Frank P. Rosengarten, Theo. Clements and Mr. Montro, of Jamestown. The character 'of the ore is copper carrying some silver and gold. The crevice is about twelve feet in width interspersed with copper throughout. Assays have been had showing it to carry from ten to twenty per cent of copper. The total value of assay including silver and gold being from ;^40.oo to ;^ 104.00 per ton. It has been developed by one fifty-foot shaft. There is also a group of four large leads of same char- acter as above, lying a mile or two further down on the South St. Vrain, belonging to Geo. W. Reardon. THE BUENA MINE Is located on Buena Hill, one half mile west of James- town, and is owned by the Buena Gold Mining Company, of Philadelphia. It has, for developments, one main shaft 112 feet deep, one leasers shaft fifty feet deep, and one No. 3 about sixty feet deep, with about 160 feet of drifts. A cross-cut tunnel has been driven 307 feet, while there has [lOl been stoped an amount 50x30 feet. There is also an open cut of ten feet. The crevice is about two feet in width, with an average pay streak varying from six to[eight inches in width, while the average width of low grade ore varies from eight to ten inches. The Buena ore is telluride in its character, and the mine has produced some of the highest grade found in the tellurium belt. Twenty-four thousand one hundred and sixty-seven pounds shipped to mill brought net ^1,947.94. A mill capable of treating twenty-four tons of ore per day has been erected at Jamestown to work the low grade ore. THE BALTIMORE BELLE LODE Is situated on Baltimore Belle Mountain, about three miles west of Jamestown, and is owned, by W. R. Lafour- cade, of Philadelphia, and H. B. Benton, of Jamestown. The developments consist of one main shaft finely timbered, seventy-six feet in depth, with fine shaft house, in which they are now placing a California whim; one shaft twenty- seven feet in depth, finely timbered, with drift at bottom fifty feet west connecting with main shaft for air purposes. West of main shaft a cross-cut tunnel has been run, cut- ting the vein eighteen feet in depth. All the openings show a crevice averaging three feet in width, with pay streak of fourteen inches, first-class ore giving returns rang- ing from ;^966.95 to ;^ 10,246.95 per ton, while second-class ore — which is being stacked at the mine, there now being some sixty tons on dump — will average ^75 per ton. The character of the ore is tellurium and rusty gold. THE BIG BLOSSOM LODE, Owned by F. L. Higby, of Longmont, is situated in Castle Gulch, north of Springdale. It has for develop- ments one main shaft ninety feet deep, with shaft house, whip for hoisting, and three shafts each thirty feet deep. From thirty feet in depth, in main shaft, a level has been run east forty feet, the breast of which shows a vein of six feet in width, the average width of vein as shown in the different workings varying from one to three feet. The character of the ore is tellurium and gold of the richest kind, assays from the croppings, six inches above grass roots, made by Mr. Thompson, of Boulder, giving returns of 282 ounces gold and 28.08 ounces silver, or 1^5,867.38. Ten pounds of ore panned out gave ^635, and the tailings brought ^5 per pound, or over ^^60 per pound for the ten pounds of ore. Twenty pounds mixed ore brought ;^407.82 by pan- ning; thirty pounds second-class ore brought ^190.20. A large amount of first-class ore has been sold, as well as of the second-class, bringing to the owners in the neighborhood of ;^8,ooo. Ore sent to mill from the dump gave returns in free gold of $26.^6 per ton. Assays have been had as high as ;^200,ooo per ton. THE ELLEN LODE, Owned by F. L. Higby & Co., is situated but a short distance from the main road on James Creek, at Spring- dale, and has been developed with three shafts, the main shaft being 100 feet deep with one fifteen foot level running west; one shaft fifty feet deep and one thirty feet deep. The crevice is very large and shows a pay streak varying from one to three feet in width. The character of the ore is tellurium and gold, that of the first-class being very rich, 144 pounds bringing ^914.44 net ; second-class bringing in the neighborhood of ^300 per ton. This property has been worked at different times by [12] lessees, and it is not known what amount of ore was ship- ped during the time, but it is estimated to be somewhere in the neighborhood of ;^2,5oo. The owners have returns of about ^8,000 from ores shipped by themselves. THE BRUNSWICK LODE, Owned by Chas. S. Schilling, is situated near Provi- dence, a few miles west of Jamestown, is a late discovery, and has been opened in several places. Two shafts have been started, which are now ten and eleven feet deep re- spectively. The crevice varies from four to ten feet in width, carrying two pay streaks, one on the foot wall eight inches in width, the other on the hanging wall four inches in width. Shipments have been made which gave returns of eighty-four ounces gold and 154 ounces silver, or ;^ 1,705 per ton net for first-class ore, while the second-class gave returns for twenty and one-half ounces gold and twenty- three ounces silver, or $Z72)-S^ P^^ ^^^ "^t, and the third- class three ounces gold and five ounces silver ; net returns ^40 per ton. The character of ore is tellurium with rusty gold. THE COLFAX MINES AND MILL, Owned by Gillette & Freeman, is situated in Central Gulch ; the character of the ore is free milling. The Colfax lode has been opened in several places along the vein by a number of shafts and ten foot holes, one shaft being eighty-five feet in depth. It is a strong contact vein, lying between porphyry and granite walls, and has a crevice varying in width of from two to twelve feet, carrying free gold that mills from ;^io to $2,0 per ton. There is now on the different dumps of this property about 300 tons of ore. The Colfax No. 2 crosses the Colfax proper near the ['3] center of its location or where the main shaft has been sunk. Several openings have been made on this lead vary- ing in depth from ten to thirty feet. The crevice averages three feet in width, the ore being free milling and averaging ^lo per ton in gold. The owners have just erected a ten-stamp mill. They have placed it in a new combination battery, with copper plates inside and copper tables below the batteries. The mill was in operation for about two weeks, but has just closed down for the purpose of putting in Frue Vanners to enable them to save much of the values contained in the iron and copper that was being wasted. As soon as every- thing is complete the mill will start up for a continuous run. The engine in the mill is a Grotorvtwelve horse power, and only requires about three-quarters of a cord of wood in twenty-four hours. Wood is abundant and costs about ;^ 1.75 per cord. The location of the mill is about i ,000 feet from the company's mine, and the work of four men will produce each day sufficient ore to keep the mill in constant opera- tion. THE DECEMBER MINE Is situated a few hundred feet northwest of the Golden Age mine, and is owned by the December Mining and Mill- ing company, limited, of Philadelphia, Penn., Sam'l S. Griffitts being President, and W. H. Johnstone Treasurer and manager, and Geo. W.Bratton. Previous to the present owners purchasing the property, it was owned and operat- ed by men without means, except that derived from the sale of ore taken from the mine, and consequently the mine was not worked either by system or with thoughts of the future. One owner panned, in one day, gold from the sur- face quartz amounting to over ;^400 in coin value, and the rich gold quartz created great excitement in the district. The developments are three shafts, Nos. i, 2, 3. No. i [«4] is lOO feet in depth, with levels east and west at fifty and lOO feet respectively. The 1 00-foot level, east twenty-five feet, shows a strong body of fine galena ore interspersed with the rich free gold streak. Throughout both levels the pay is well defined. Shaft No. 2 is io8 feet west of No. i, and has reached a depth of fifty feet, being connected by level with No. i, thus affording perfect ventilation. The free gold quartz in these openings is strong, and the richest specimens are hfere found, selected specimens assaying over ^100,000 per ton, the lower grade ore milling on an average $77.60 per ton. The galena streak is some two feet in width, assaying sev- enty-one ounces in silver and twenty- five per cent lead. Shaft No. 3 is twenty-five feet in depth, showing an average body of quartz as in the other workings. A tun- nel site has recently been located in Castle Gulch for the purpose of driving a tunnel to cut the vein at a depth of 500 feet. A mill site has also been located and contracts let for erection of engine and hoisting apparatus. The present company are a close corporation, and will exten- sively develop the property. THE EXCELSIOR LODE Is situated on the southern slope of the divide near Left Hand Creek, and a short distance below the Mountain Chief mine, and is owned by O. Christopher and W. C. Boice, of Rockville. It has been developed by one shaft thirty feet in depth, and a tunnel has just been started which is now in under cover ten feet. The openings show a crevice about six feet in width with a pay streak proper of about two feet. A mill run was had on the whole pay streak, which gave returns of twenty-six ounces silver and six-tenths of an ounce of gold. Ore assorted from the streak gives returns of ninety-six ounces silver and one and a half ounces of gold, or ;^ 13 5. 00 per ton. IS. THE EVENING STAR LODE Is situated about one mile west of Jamestown, near the Balarat road, and is owned by O. N. Heckman and John Williams, of Jamestown. The developments consist of one shaft twenty-five feet deep, and a tunnel started on vein about twenty feet in length showing a crevice of four feet in width between walls carrying a pay streak varying from five to ten inches in width. The character of the ore is galena with some grey copper, and gives returns ranging from twenty to one hundred and fifty ounces in silver with a little gold. EXCELSIOR LODE Is situated on the Balarat road about two miles from Jamestown, and is owned by John Waterman, of Jamestown. It is developed by two tunnels, one partially a cross cut forty feet in length, the other running on the main vein eighty feet, showing a crevice four and one half feet in width with a pay streak of over three feet of free milling gold ore. The crevice is enclosed by well defined granite walls, the average pay streak giving returns as follows : 1st class, 14 ounces of gold to the cord of ore. 2nd " 7 " to lo ounces of gold to the cord of ore. THE EARL LODE Is owned by E. D. Moffett, of Springdale, and M. Bagley, of Longmont, and A. R. Golden, and is situated in Castle Gulch, near the " Big Blossom" and "Grand Central," and north of the town of Springdale. It has been developed by one shaft fifty feet in depth. The crevice averages four feet in width. First class ore shipped brought as high as ;^ 10.00 per pound, the second class averaging ;^250.oo per ton. Specimens of this high grade ore are on exhibit in the show-case of the district. [,6J THE GOVERNOR GROUP MINES Are located a short distance south-east of Jamestown. They are ten in number, viz : The Governor, President, Charter, Denver View, Fannie H., Star of the North, Phil- adelphia, Jamestown, Annex and Junction. The developments consist of five shafts sunk to depths of from fifty to seventy-five feet, and a cross-cut tunnel now six hundred teet in length, which when completed will inter- sect all the leads but two. This tunnel was commenced in December, 1881, and at a distance of one hundred and fifty feet from the mouth, and for a hundred and fifty feet beyond, a succession of blind leads \ycre discovered of iron and quartz, the pay strea^ks, of which assayed from ;^20.oo to ;^40.oo per ton. At. a' distance of four hundred feet the Denver View and Star of the North were cut near their junction; the pay streak of the first being twenty inches in width and the ore assaying ;^30.oo to the ton in silver, the pay streak of the latter being four feet in width, the ore as- saying $64..oo to the ton in gold. The Charter vein was met with at 475 feet, the assays from which varied from ;^20.oo to ^$34.00 per ton in gold and silver. The Philadelphia was intersected at a distance of 525 feet, showing a pay streak of twelve inches and assaying ;^25.oo in silver. The Presi- dent, which is supposed to be the most valuable of the leads, will be cut at right angles to the tunnel at a distance of less than 700 feet. From a shaft sunk on this lead some rich ore was obtained at a depth of seventy feet, assays ranging from ;^ 1, 000 .00 upwards, having been taken therefrom. The tunnel is being driven principally with the object of devel- oping the vein. The veins are true fissures, and vary in width from three to twelve feet. The character of the ore in the various leads differs greatly, some being amalgama- ting, and others smelting and refractory. The remarkable nature of these leads has caused much comment from ex- perts and scientific men who have examined them, and is [17] generally acounted for in the fact that the great gold and silver belt of this and adjoining districts passes through the Governor Mountain, on which the Governor group of mines is situated. For the purpose of experimenting upon and treating these ores a large mill has been erected on Jim Creek near Jamestown which has been in operation since May last. The mines and mill are owned by a Philadelphia com- pany, of which Frederick M. Adams, Esq., is president, H. D. Hughes, secretary, and C. I. Cragin, Treasurer. The offices of the company are at 312 Stock Exchange Place, Philadelphia, Pa., and at Jamestown, Colo. GREAT EASTERN LODE above Jamestown on Little Jim Creek. It is owned by A. J. Corlcle and A. F. Rayford and J. C. Carter, of Denver. Its developments are a tunnel on the vein sixty feet in length showing a crevice varying from seven to eight feet in width enclosed by good granite walls. The pay streak averages from three to four feet, the character of the ore being galena, returns giving from first class $7^.00 per ton, second class ;^20.oo per ton, with a fair per cent of lead. THE GOLD DIRT Is located about one mile west of Jamestown near the Balarat road, and is owned by G. B. Stanley and son, of Jamestown. This is a new discovery and is a free gold lead giving fine pannings from the surface. It has a crevice of eight feet between walls with a pay streak varying from ten inches to two feet in width. No shipments have yet been made, the location work not yet being completed. THE GLADIATOR LODE Is situated at Springdale, and in its north-eastern course crosses the main road about three hundred yards below the 2 [18] Seltzer Hotel. This property is owned by Cyrus Taylor, of Springdale. The ore it furnishes contains nearly all the tellurides, combined with free gold, known in mineralogy. The developments consist of a main shaft lOO feet deep which shows a pay streak proper averaging from five to twelve inches in width, while accompanying it is about three feet of second grade ore ranging in value from $20.00 to to ;^6o.oo per ton. A new shaft is being sunk and is now down some twenty feet, from which has been taken in the past three weeks over ^800.00 in first class ore besides a large amount of second grade ore. There are four other openings varying from four to ten feet in depth, all showing high grade ore. The croppings of this vein can be traced through the country for a distance of one and a half miles, and shows a width varying from ten to twenty feet. First class ore without trimmings brings ;$4.oo per pound, and second class ;^2,ooo.oo per ton. THE GRAND CENTRAL LODE Is situated in Castle Gulch one mile from Springdale. It has been developed by two shafts, one ninety feet, the othec twenty feet in depth, and a tunnel in on the vein 125 feet, and by a number of openings varying from four to ten feet deep, proving up the crevice for a distance of over 1,200 feet, in all of which was found gold and tellurium. This property has been worked mostly under bond and lease, and its production can only be estimated at between ;^2,ooo and ;^ 3, 000.00. The crevice is immense varying from ten to fifty feet in width and the pay streak ranges from four inches to four feet. It is owned and being worked at present by J. M. Fox and S. W. and S. R. Cole, of Longmont, and J. V. Sybrandt, of Springdale. One hundred pound lots of ore have been sold at the rate of ^7,000 per ton, and ton lots averaging i^i/o pe while assays have been had as high as ^^ 160,000 per t* r ton, ton. THE GOLD RING LODE Is situated on the divide between Jim Creek and Left Hand, on southern slope near Left Hand Creek, and is owned by Mrs. Laura B. Hackley, of Boulder, and Mrs. Hannah Richards, of Denver. It has for developments one shaft thirty feet deep and a tunnel on the vein forty feet in length. The crevice varies from twelve to fifteen feet in width as seen without finding either wall. Shipments of ore from across entire crevice gave returns of ^96.00 per ton, 600 pound sample from dump gave one p.or?- six-tenths ounces gold. This ore can be successfully treated by concentration with frue vanners. THE GRAND UNION Is situated on the divide between Jenks and Castle Gulch, a short distance from both Jamestown and Spring- dale, and is owned by G. Holzinger and Wm. Bramwood, of Springdale. There is a shaft eight feet in depth and a cunnel on the vein some forty feet under cover. The crevice varies from six to eight feet in width, in places being much wider, the pay streak ranging from two to eight inches in width. This property is being opened up and no shipments have been made, it being a late discovery. Assays have been had ranging from ;^57.20 to 1^148 in gold. The charac- ter of the ore is tellurium. THE HUMBOLDT LODE Was discovered by L, Fredericks, an old prospector, and, upon the discovery of carbonates, sold by him to Dr. McBeth, of Denver. It is situated about one half mile north of Jamestown, and is developed by one shaft about forty-five feet in depth. [20] The ore is galena, containing from twenty to forty ounces in silver, with about twenty-five per cent lead, show- ing in many places carbonates. A large amount was shipped to Omaha for treatment, but the owners being absent, we are unable to give the re- turns. It being the only lode in the district showing the same character of ore, has given it a reputation as a curiosity. INVINCIBLE MINE Is situated about one half mile northwest of James- town, and is owned by the Invincible Mining company of Denver, of which R. R. Newkirk is President. The origi- nal discoverer was Goldsbury Stanley, who, working by himself for a long while, made considerable money by stripping the surface quartz and milling it in a rude roaster, in which he saved free gold at the rate of ;^8o to the cord. The present developments are two shafts, one sixty feet in depth and the other twenty feet in depth. The sixty foot shaft is covered by a good shaft house. The vein is enclosed by good granite walls, the crevice being seven to eight feet in width, with a pay streak vary- ing from one and a half to two feet in width. The character of the ore is free gold and iron pyrites, for which the smelters pay as follows: First-class, 1^152 per ton; second-class. $'j^ per ton. IRON QUEEN LODE. The Iron Queen is the name of a location on a large deposit of hematite of iron, which shows extensive crop- pings for nearly one mile, but which has never been ex- tensively prospected, the ore not carrying over three to five ounces in silver, the only developments being a ten foot shaft and a few open cuts, which, however, disclose a vein of solid "hematite" of from three to eight feet in width. [21] The croppings and large quantities of float from the size of a hen's egg to chunks weighing 200 pounds and over, ex- tend from the flat just north of Jamestown west at least 5,000 feet. The owners are anxious to develop the prop- erty and find what underlies the iron deposit, and offer an interest to capitalists willing to test it. The locators are B. G. Strock and Wilson G. Clark, of Jamestown. THE JOHN JAY MINE Is situated on James Creek, about three miles west of Jamestown in a pleasant location, easy of access, in the midst of a body of excellent timb'^r. It was one of the first 'tellurium discoveries and is held by a patent from the U. S. government, which calls for 1,500 feet in length by 150 feet wide on the vein. The strike of the vein is north 30° east, and it dips to the north about 80° from a horizontal. It is a strong, well defined true fissure vein from four to seven feet between good solid walls of porphyry and slickenside. The ore is tellurium, principally of the class known as sylvanite. The developments consist of one main shaft situated in the center of the claim, 250 feet deep, with levels running east and west, aggregating about 550 feet in length, connecting with air and other shafts. The surface improvements are an engine, shaft and ore houses, assay office, smith shop, stables, office and dwelling house. It is equipped with good hoisting machinery, driven by a new 15-horse power steam engine. This property is owned by A. J. Van Deven, of Boul- der, one of the original discoverers, who, during three and a half years, working a small number of men, mined 175 tons of smelting ore, receiving for the same over ;^75,ooo, or an average value of 1^400, or ;^5oo per ton; and in ad- dition to this a large quantity of low grade or milling ore [22] worth from ;^20 to ^^50 per ton, for which he received over $7,S^o, There is also in connection with this mine a good mill site and water power on James Creek, upon which is a good double-issue 5-stamp mill equipped with four Rouse's concentrating tables with all the necessary machinery com- plete. This mine has produced some of the finest high grade tellurium ore ever found in the State, if not in the world. THE J. ALDEN SMITH LODE Is situated in Castle Gulch, near Springdale, and be- longs to parties living in Logan, Kansas. This property has for developments one shaft seventy-five feet deep, while a cross-cut tunnel is being driven which is now in under cover about 150 feet. This cross-cut, when in 225 feet, will cut the vein 200 feet deep. The crevice in this lead averages five to six feet in width, with a pay streak varying from two to twelve inches in width. The character of the ore is tellurium, the specimen ex- hibited in the show case of Central District having been roasted, the heat dispelling the tellurium, leaving the gold and silver in its native state. THE JOE DANDY LODE Is the east extension of the "Brunswick," is a new discovery, and is fast being opened. It is owned by G. T. Hoge, C. S. Hawk, B. G. Strock and Chas. Du Bois. The character of the ore is telluride — the same as the "Bruns- wick," it being on the same vein. Assays of streak at sur- face, thirteen and one-quarter ounces g®ld ; silver, one and three-quarter ounces; value per ton, ;^262.92. [23] THE ROANOAKE LODE Is an eastern extension of the "J^^ Dandy," and is owned by Harrison Bickel, C, S. Hawk and G. T. Hoge. This is also a new discovery, and is just being opened. It is on the same vein as the Brunswick, the ore being of san>e character, viz: telluride. Assays of whole streak have been had of from ^75 to ;^ioo per ton. THE LONGFELLOW LODE Is situated in Central Gulch, and is owned by a com- pany in Jacksonville, Ills., of which T. F. Simmons is Pres- ident. The production of the mine under the present man- agement has, up to date, been in the neighborhood of ;^ 1 0,000. The main shaft is 120 feet in depth, and is cov- ered by a substantial shaft house 26x50, the hoistmg being done by a California whim. From fifty feet levels have been run east twenty feet and west forty feet, and at ninety feet levels have been run east eighty feet and west fifty feet. A tunnel has been run starting at a point 380 feet east of the main shaft, which is now in about 275 feet, and will strike the main shaft ninety-three feet in depth. The pay streak throughout the tunnel averages ten inches of low grade ore, which mills $J^, In the bottom of the shaft there is about one foot of pay, which will mill from ^300 to i^SOO per ton, the first-class being from ^^300 to ;^500 in silver, with twenty-five per cent, of copper. The low grade ore will concentrate six tons into one, giving a re- sult of $\\0 in silver per ton and six per cent of cop- per. Prior to the purchase of the property by the present owners some ^3,000 was taken out in sinking seventy-five feet, giving the total production at ^13,000. The vein is very strong, showing good walls. The character of the ore is gray copper with some galena. [24] THE MONITOR LODE, Owned by Wilson, Stanley & Co., of Jamestown, is situated about one mile from Jamestown, near the Balarat road. The main shaft on the mine is some eighty feet in depth, and shows eight inches of first-class ore, running about ;^300 per ton. From thirty feet in depth a drift has been run east about fifteen feet, which shows a pay streak fourteen inches in width, which has given the following re- sults : No. I — li ounces gold an^ 78! ounces silver; valued $115.0x3 per ton. No. 2-;J^ " " 42i " " 58.57 A shipment of two tons gave net per ton ;^64, with no allowance for lead ; another shipment gave ;^58 net in silver and one half ounce in^gold per ton, and thirty-six per cent for lead. A second shaft has been sunk twenty feet; the character of the ore is galena. ' At the present rate for lead, the value of the ore would be increased some ten dollars per ton, sufficient to pay the cost of mining. THE MAY QUEEN LODE Is situated about three-quarters of a mile north of Jamestown, and is owned by the DuBois Bros, of James- town. The character of the ore is free gold, and is free milling. It has only been developed by the location work, viz : a ten foot adit. The crevice, as seen, shows a width of about three and a half feet with a pay streak proper of two feet, which gives returns ranging from ^20 to ;^40 per ton. THE MERGE LODE Is situated near Springdale, and is owned by Thos. Clements and Dr. J. B. H. Janeway, of Jamestown. It has been developed by two shafts, one twenty-five feet deep, showing a three-foot vein with grey copper interspersed throughout the entire width; the oth^r, thirty feet deep, showing a vein of about eighteen inches in width, but car- rying a much finer quahty of mineral, it being more con- centrated, returns having been had ranging from eighty to 200 ounces in silver per ton. THE NIAGARA Is located about one half mile west of Jamestown and adjoining the Buena mine, being a parallel vein. It is owned by Henry Sherman, F. C. Buchardee and Theo. Clements. This is a late discovery, and contains very rich ore, its character being tellurium and rusty gold. The crevice averages four feet in width and is all pay, tellurium and rusty gold being scattered thrcvighout the entire mass. First class ore from this property will run in the neighbor- hood of i^io per pound; and the second-class, which com- prises the whole body, mills at the rate of some ;$8oo per ton. ORLANDO MINE Is situated on Golden Age hill, about 600 feet from Golden Age mine, and is the probable extension. It is owned by the Golden Age Group Mining Company, of Philadelphia, of which C. E. Rogers is President, and Geo. DuBois Superintendent. The main shaft is fifty-three feet in depth, showing a crevice of nine feet enclosed by porphyry and granits walls. The pay averages eight feet wide, from which samples, taken from different places, gave returns of ;^ii5 per ton. On account of complications in the east, the mine is for the present lying idle. THE OCEAN WAVE LODE Is the northeast extension of the Standard lode, and is owned by Robert Peter, Jr. The width of the vein is four feet; the gangue is green stone porphyry, and the [26] country rock granite, the ore quartz containing auriferous pyrites and copper.

THE PRINCESS LODE, Was discovered on the 31st of March, 1882, by Rich- ard Ball and M. M. Cavanagh, who afterwards sold a one- third interest to Mr. J. A. Decker. It is situated in Central Gulch, adjoining the Longfellow mine. The character of the ore is galena, there being four separate streaks in a crevice which shows a width of six feet. Developments are a discovery tunnel in the center of territory, fifteen feet under cover on the vein, and a shaft sixty feet east, twenty-five feet in depth. On the foot and hanging walls are found streaks of galena ore varying from four to six inches in width carrying gold in a free state, attached to the quartz, and in cells and cavities in the center of the galena, the two central streaks carrying principally silver with a small amount of gold. The following is the result of the assays from different portions of the crevice at a depth of four feet, viz: [27] I lot, 15 ozs. silver, value, per ton, - - $16.50 I '* 29^ ** " X 02. gold, value per ton, 37.45 I " 32>^ " " X oz. " " " 40.75 I " 80 " " }4oz. " '* " 88.00 These returns do not include the value of the lead which runs fifty-seven per cent. The galena streaks carrying gold give the following at a depth of twenty three feet: 725^ ozs. gold, and 102^ ounces silver; total value per ton, $i,SS7-7S' The central streak at twenty -three feet: gold 24- 10 ozs., and silver 83 ^^ ozs.; total value per ton, ;^ 139.8 5. THE PET MINE, Is situated near the head of Central Gulch, and was discovered and is owned by the DuBois brothers, of James- town. ^ The quartz found on the surface was very rich in free gold, and the vein showed a streak of six inches. The first shipment of the precious metal was obtained by pounding the ore in a common mortar and panning; two of the brothers obtaining in this way ^$32.00 in two days. The next shipment was milled at an arastra. One thousand pounds of first class ran at the rate of 194 ounces per cord, or ^3,880, and the second shipment 36 ounces per cord. The scrapings, run in an arastra built by the owners, ran at the rate of twenty ounces. A shaft is now down forty feet, showing a pay streak of fourteen inches. A good shaft house covers the main shaft, containing blacksmith outfit and all the nec- essary conveniences. The vein has been stripped on surface in different places for about 200 feet, prospecting well throughout.
