Show Salt Lakers' Idaho Proposition Continues to Market Rich Copper Resources. SYSTEM OF MINING IS MOST INTERESTING Extremely High Values Obtainable Obtain-able and Sent to Market All Without Sorting Word has reached the local offices of the Weimer Copper conipan" that the mine management has ,iust forwarded an additional car of hijli-rado copper ore to tho local market. This will make the third car that this remarkable organization has made within recent date, and while its values must remain re-main au unknown quantity until received re-ceived at the samplers, it is thought that the values will equal, if not exceed ex-ceed those of tho previous shipments, the latter ranging around 17 and IS per cent rod metal. This companj owns a largo acreage of mineral ground about fifty-live miles from the shipping point of Dubois, Ida., and the more recent history of I he mine, or shire the ownership owner-ship has vosted in prominent Salt Lake hands, discloses an exceedingly interesting inter-esting account of gigantic minfng on a small scale. The present company has had little opportunity to accomplish other thau development work, which, necessarily is small in proportion to the extent of ground to be covered, fn a recent, report re-port of a prominent expert, the pres-ont pres-ont system of mining and the general geography anil geology of the group are given, which will prove of interest to the stockholders of this red metal producer. pro-ducer. In part this report is as follows: fol-lows: The ore Is covered with a wash of gravel grav-el and earth fro mi wo to six feet deep, and In order to mine the ore plows and scrapers are used to remove the wash, which Is dumped down tho hillside, thus exposing the ore body, which Is then broken down by means of one and a half-Inch steel drill sixteen feet long attached at-tached to a sixty-foot spring pole. A hole Is drilled through the ore and rock fourteen four-teen to twenty feel deep, charged with four to seven kegs of black powder which when fired loosen 150 to 300 tons of material. ma-terial. The rock Is dumped over the dump, the lower grade ore Is stacked up between the tracks and left for future disposal, while the shipping ore Is loaded Into mine cars and run to the ore bins, from which the wagons nre loaded for transportation to the railroad. Tho ore Is hauled to Dubois station, Ida., a distance of fifty miles by wagon over a good road. Each teamster has a string of three and four wagons hauled by twelve to sixteen nnd twenty horses, who average about a ton to each horse. I made a inorough examination of all the ore when exposed In November. 1906. the average of which, at that time, was 10 (per cent. I found several of the fissures carrying gray copper and chalcopyiite from six to twenty-seven Inches In thickness, thick-ness, that assayed 50 per cent to 62 per cent. This property was located, owned and operated by A. P. Tullgren since 1S86, and he Informed me that-he had shipped eight cars of hand-picked ore to the smelter at the rate of about one car a year for the last eight years, which averaged aver-aged from 35 to 12 per cent copper per car, by the carload. Mr. Tullgren did this mostly alone nnd packed the ore on burros and sleds live miles to the wagon road. Since the Weimer company began operation, oper-ation, in December, 1906. they have shipped three carloads straight shipping ore (not picked), the first of which contained con-tained 35 tons of a net value of $15S6.89; tho second of 3S tons of a net value of $1549.81, and the third car of 51 tons Is now In transit. The Weimer company has built a good wagon road from the mine to the main road. The heavy ore teams can now load ore at the mine. There Is also a system of good roads to all points on the company's property. The camp consists of four log cabins 14xlS each, to accommodate 4S men in comfortable sleeping quarters, cook camp, celler and a dining-room to seat 60 men, one largo commissary, toolhouscs, blacksmith shop, barns and office building. About 200 'of the 318 acres held by this company Is heavily timbered with pine limber. The property is situated In the unsur-veyed unsur-veyed part of township 10 north, range 30' east of the Boise base and meridian, in Skull canyon mining district, Idaho, and about fifty miles west of Dubois station sta-tion on the Oregon Short Line railroad, at an altitude of about 7500 feet above sea level and on the west slopo of the Bitter Root moutnalns. This mine embraces an area of 34S acres, consisting of eighteen lode locations, all of which have been surveyed for patent. The geological formation for-mation consists of a bed of quartr.lte, overlaid with a carboniferous limestone on a dip of about ten degrees to the northeast and Into the mountain. Tho apex of this quartzite and limestone Is exposed ex-posed along the west side of (he range of mountains and extends for several miles north and south of this properly The ore is all copper ore and Is found In the llrrjcslone near the quartzite wheru It occurs in beds cut by vertical fissures cutting through the limestones, which are filled with rich deposits of copper cop-per ores and spreading and taking the place of the softer limestone for several feet each side of the fissures, In places forty to fifty feet wide and of vailed thickness. This formation of the ore bodies extends for 8000 feet northerly and southerly through this property, following the contour of the mountain, and Is exposed ex-posed by open cuts nnd tunnels the entire length. |
