J Elk City, Idaho, March 26, 1904 $3.oo The Year Vol. I, No. 13 TiTe BUFFALO HUMP CAMP Robert N. Bell, State Inspector of Mines, in His Report on the Hump District, Gives Much Interesting Information Relative to the Formation and Value of the Ore. The discovery of: the Buffalo Hump veins in 489,8 Waa made the basis of one of those Wild and woolly mining booms for which the western mining states are noted. The boom was shortilivsd, how ever, for when the snow meltèft- off the stories of great wealth, it was found that to win it would evolve no small in vestment of money, muscle and time, but the snow did not melt the big led ges of gold-bearing quartz, which are still there, and just as big as ever, and their recefit development is such as to warrant the anticipation that the glow ing fairy tales told of their riches will be justified by the facts and actual bul lion 'ät no,cfistant day. The Buffalo Hump district probably holds the- record for receiving the high est, price for a ten foot hole in the whole mining history of Jthe state. Mr. Charles Sweeny»"'"Who recently launched the big thirty rftfllion dollar merger in the Coeur d'AleneS,« offered a quarter of a million dollars casivfor the Big Buffalo vein, when its development did not exceed ten feet in depth, which figure was refused by the owners ; he afterwards bought the property, 'when the excitement had died down a little, for about half that sum. The Buffalo Hump summit is a sharp hog back elevation of bare granite, which, viewed from some directions, roughly resembles the outline of a buf falo's back. The culminating point, or hump, has an elevation of eight thou sand eight hundred feet above sea level; it is situated on the divide between the South Fork of the Clearwater river and the main Salmon river and is the high est elevation in a region of mountain country fifty miles square. >,, The country rock at the Hump dis trict is practically straight eruptive gray granite of medium coarse grain. There are no dike rocks exposed over the present central area of the district, covering a belt of country six "miles long by two wide, but this belt contains a parallel system 1 'of monster fikéure veins of quartz that stands nearly -Ver tical and strike almost due north and south. 1 Well posted local- miners say that ' this belt contains a "quartz vein from workable size up to 60 feet wide for eVery six hundred feet of its width, and after studying the surface of the belt for awhile one will easily come to the conclusion that the statement is not an exaggeration. -.The surface appearances of these gt^at fissures are not attractive, owing t6 the excessive local ice action which ha® worn the veins down even with the enclosing granite walls, and at the présent center of the district, including ttxe Hump postoffice and Concord post office settlements, some of the biggest ore bodies are situated in a broad flat glacial basin full of little benchy flats and swamps that form the head of Sheep creek, in which'situation the big veins are naturally eroded even with the enclosing formation and inconspic uous. f ; The Big Buffalo ledge, owned by the Buffalo Hump Mining Company, is lo cated oh- the west side of this basin and forms tbb bed of one of the tributaries of- Sheep creek, which has cut a V shaped trough along the soft wäll of the vein for four thousand feet, expos ing a succession of'fine ore shoots for that distance; then the grad$ of the country drops off very rapidly,' 1 ^ and at thè first big drop an adit tunnel has been started on the vein which' is al ready in several hundred feet. It the intension to drive this tunnel • back on the vein to the north which will de velop the We shoots as it goes along and undercut the discovery shoot,'at This t 1 • vertical depth of nearly six hundred feet. f f This property was opened by a shaft located at the discover^, on a little swampy bench near Hump town, shaft is reported to be two hundred and fifty feet deep and in a crosscut at the bottom level is said to show sixty feet of quartz between walls that carry over ten dollars in gold per ton on an aver This shaft produced some aston age. ishing rich native gold spedmen ore, pieces v of which äre still s'éferi" around the camp, that are nearly half gold. A ten stamp mill was put on this property and run on a body of oxidized ore that was mined above a sixty foot level in the shaft. This ore body was mined seven sets wide and seven sets high by about one (hundred arid sixty fqét long and is locälly reported to have produced gold bullion to the -fralue of $250,000. From a part of this opera tion a tailings pile was saved' said to contain 6,000 tons and average value of five dollars per. ton in gold. — Owing to the enormous expense of pumping a shaft located in a ''swampy creek bottom, this operation vVds dis continued until the ground could be opened by the new drain tunnel now in progress. The company's managers claim that the operation of the property did not pay, which is probably true under such adverse conditions, but the report that they have secured seventy claims in the district would indicate their faith in the future. After it is properly developed and equipped with the necessary mill ing capacity, run by water power, of which the company has plenty available and near at hand, all the gold won out of the ore of this great vfein over two dollars a ton should be ne\ profit. The veins of the Buffalo Hump are very clearly defined when opened under ground, and the ore shoots range from fifty to five hundred feet in length; the walls are usually smooth and hard, fre quently polished, and tjie ore shoots are filled with a rather ribbony banded white quartz next to the walls that shades into a more massive variety towards the center with small vuggs lined with glassy crystals; they have evidently been formed by ascending mineral solutions that filled pre-exist ing fissure spaces. This district is the highest in the region, has suffered less erosion than the adjacent country and the values are more likely, for this rea son, to extend to greater depth than in a placer district, the erosion of whose veins have produced millions of dollars worth of placer gold, like those of Elk City and Florence, neariât hand. The great quartz ore shoots of this district are usually quite thibkly sprink led at a short distance below the sur face with banded lines and rich dissem inations of iron pyrites, together with a varying mixture of copper, lead and zinc sulphides with free gold, The lead mineral here, as is usual in most Idaho gold mines, indicates the richest gold values. The free milling tests obtained in this district vary from different veins, and in fact from different parts of the same vein. The deepest ore now being mill ed in the district is from the Jumbo vein. It is a straight hard white quartz from a depth of five hundred feet on the v*in; it is richly sprinkled with iron sulphides, but shows occasional colors of native gold. The milling results save sixty per cent of thé total value as free gold, fifteen per cent in the form of high-grade concentrâtes, and the bal ance-going into a tailing pit for future treatment by cyaniding, to which meth od it is said to yield ninety per cent of the refnaining values. Practically the same results as'aBove were obtained on Cracker Jack ore, some of their higher grade material showing a little less free gold extraction, "tHit just as good results on cyanide tests. 1 The country immediately adjacent to Sheep creek basin is very rugged and abrupt, a succession of'deep cut can yons carrying'large creeks and whose steep slopes are densely timbered. This topography will be appreciated by the statement that frohx the head of Sheep creek at » Hump town to where the creek joins the Salmon river, the dis tance Is only fourteen miles and the fall is fiftÿ seven hundred and fifty feet. These conditions mean a great deal for the economical development and operation of these veins. The only properties producing in the Hump district during 1903 were the Jumbo and the Cracker Jack mines; their combined milling capacity was equal to about one ten stamp mill and their total bullion yield was one hund red and twenty-six thousand dollars. The five stamp mill at the Cracker Jack was increased to ten in August and then shut down 1-November first, pending the installation of electric power. The four stamp mill at the Jumbo was increased" to fourteen in 0ctobel% and again t0 . twenty-four on Dece mber 25; the last ten are expected ftQ be commission by the tenth of January. < ? The new mill building at the Jumbo, built during the year, is of thirty stamps capacity, and the remaining six stamps will be put in during the winter to make it completed This is one of the most substantially built and most conveniently arranged mills in the west, and contains, besides the stamp and vanner floors, a three drill air compres sor and electric light plant, the whole run by water power using two Pelton wheels fed by sixty inches of water under a head of six hundred and eighty feet. (Note.— The remainder of Mr. Bell's report on Buffalo Hump will be pub lished next week. ) Lake News of the Hump Four feet two inches of good ore has been cut in the Del Rio showing free gold in liberal quantities and the own ers are jubilant as a result. It was not expected to find an ore shoot short of 500 feet, so the present strike is very gratifying. Ore has also been cut in the Oro Fino, twenty feet being in sight but no values can be learned. The Ajax north drift is now getting into the ore, it having been run 145 feet and crosscut 45 as well as 140 feet south and 25 feet crosscut. The Atlas company are sinking stead ily but owing to the large size of the shaft slow progress is seemingly being made.

Is Located on Guartz Creek, near Orogrande. ''The The Lewiston Tribune says: Diamond Hitch group of mining claims located in the Elk City district, was yesterday bonded by Orin Lamb to Frank Brown of the" Jumbo Mining company. The bo'd embraces three quartz claims, the Diamond Hitch placers and the water right. The price could not be learned but is understood to be Stiff one. ''"When seen yesterday Mr. Brown stated; 'T have secured a bond on the Diamond Hitch property because I be lieve the property a very promising one and only needs development to make mine. There are three ledges running parallel and we will start tunneling on these ledges simultaneously. This work will commence as soon as the supplies can be' moved in, which will be very soon, and the active work of developing the property will then be Vigorously prosecutéd. It is expected that about 1600 feet of punneling will be run this property, during the coming summer which should give a fair idea of the character of work to be done," ''The Diamond Hitch group was dis covered by Orin Lamb about two years ago and from the amount of work done I ALBERTAS CROUPIS SOLD Capitalists,, From Jackson, Michigan Buy Property in this District.— J. A. McEachran of Spokane to Commence De veloping the Property at Once. J. A. McEachran 'arrived in camp Sunday, after spending the greater part of the winter outside. He came in to begin develop- y Hient work on the Albertas Group, which will be carried on extensively the compning season. This group comprises eight claims, the Albertas Nos. 1, 2, 3 and 4, the Spotted Deer Nos. 1 and 2, and the Moose Horn Nos. 1 and 2. Upop; seven of these claims are quartz ledges .varying from three tg eightyfeet in width and açe explored by . 300 feet of tunnels, shafts and crosscuts showing values running from $2 to $4Q,perjton.

In many places tibe surface erosion pans rich.in freej'gold, while the auriferous- mass assays from $1 to $4 pier-ton. The ores on these claims underwent a series of .tests which demonstrated their worth to Mr. Potte of Jackson, Michigan, who with GeojW- Carter and other Michigan capitalists have taken over enough'stock to enable the Company to not only develop the property thoroughly, but.'to install any sized mill desired. As a preliminary step in line with the extensive development projected, a shaft will be sunk 100 feet on the quartz veins of Albertas Nos. 1 and 4 and enough drifting will be done to enable the Company to arrive at an intelligent estimate of what other preliminary woyk is,needed upon these claims before installing their mill. Upon the Spotted Deer which com- ' prises the dyke, a 500 foot crosscut tunnel will be run besides drifts By running in from the Red Éiver side of the * mountain, a depth of 1000 feet can be secured on this dyke in a distance or 1500 feet. Ample water power can be secured from Red River to run any number of stamps up to 1000, the fall of this stream will exceed 100 feet to the mile. This promising group was formerly , controlled by the McEachran Brothers and James Slavin of Spokane, all of whom it is understood still retain a heavy interest. Mr. J. A. McEachran will be general manager, which is equivilant •> to saying that every dollar expended will be placed whtere it will do -* the most good, the kind of management, by the way, which the camp needs and all that it needs. v '.it Üb and surface work. Yellow Jacket Has Rich Ore Ur ; H. P. McCarthy, manager of the Yellow Jacket, came in from, that group, Wednesday, and reports a phenomenal strike in shaft No. 2, of two and a half feet of very rich ore. In proof of his state ment, were proof necessary, Mr. McCarthy brought in a piece of rock, weighing about Eighty pounds, which, fairly glitters with na- ' tive gold, copper pyrites, and iron sulphide?; it is alêb heavily im pregnated with a brown hematite (oxidized sulphide). There is besides a redish brown oxide which appears to belong to copper. Altogether it- is one 'of the handsomest specimens thus far produced in Elk City. Mr. McCarthy shipped it to Spokane to Mr. Lusk, of the Badger Improvement Co. This strike was made at a depth of thirty two feet and reproduces the characteristics of so many other • fine properties iri this camp, that is to say, the values increase witli ' ' depth. The development work thus far has been confirtëd' to the Yellow Jacket No. 2, and consists of shafts Nos. 1 and: 2, which are 1200 feet apart. No. 1 is down fifty feet and shows good and increasing values with every foot of depth attained. A 250 foot tun nel is among the improvements intended in the near future. has made a remarkable showing. This property is listed in the mining bureau as one of the most promising prospects in the Elk City district.. The property lies between Elk City and Buffalo Hump and is believed to be one of the richest deposits in the district. Mr. Lamb has opened the three veins in several places and in every instance rich ore has been taken ouf ''The deal is considered of vast im portance by mining men as thé gpening v of the property will, create an in tex-est in other px-operties in the district that must be developed by outsidé cap ital on account of the limited me^ns of, the present owners. " This should mean a good deal for the Elk City District, when a man of Rrank Brown's prestage, wpll earned as his is, goes into a mining district it means that that district is well beyond the experi mental stage. We believe the time is near when those who's faith in the Elk City district never wavered are about to reap the reward justly due their per severance. It is to be hoped that Mr. Brown's luck will not desert him in his up a a rf new field.
