We TA y ·L OR, ON THE MINERAL RESOURCES OF TH:E UNITED STATES EAST OF THE ROCKY MOUNTAINS. WASHING~l>:~r, lifa,y 2, 186S. Srn: In pursuance of your instructions of September 12, 1866, I had the honor on the 13th of February, 1867, to present for your consideration a pre­ liminary report, embracing a general view of the gold n,nd silver districts of N cw Mexico, Colorado, Montana, Dakota., and Minnesota, with some notice of tho gold recrions of the southern Atlantic sta,tes, Canacfa and Nova Scotia. Tho prcscn report will include a further inquiry into tho rninentl resources of those dis_tricts, with special reference to their situa,tion and 'prospects at the expiration of the year 1867; and I propose as a not inappropriate sequel to devote a considerniblo portion of this communication (1) to a general review of the production of gold and silver in other quarters of the ,vorld, with the purpose of indicating refa­ tively tho commercial and social importance of the treasure product of the U nitod States, and (2) to a summary of the dolnestio commerce from the Mississippi river westward to the interior or mining districts of the United States, having · reference prominently to railway communications with the Rocky mountains and the Pacific co[tst. 1-'HE GREAT PLAI:NS. Between tho agricultural districts ·of Dakota, Nebraska, Kansas, Indian terri­ tory, and rrexas, which extend westwarcUy to the 98th .meridian of longitude, and tho eastern Piedmont of the Rocky mountains, and in Colorado n,re bounded eastwardly by longitude 104°, the cretaceous formation, onco qesig­ nated as the '' American desert," is now well understood to be adequate for the sustenance of ca.ttle, and if subterranean sources of water supply were avnil­ able for the purpose of itrigatien, might become an agricultural region. At present this wide interval between the margin of the Missouri river, whore the moist winds from the Gulf of Mexico afford a sufficient fall of summer rain for the growth and maturity of crops, and the Colorado Piedmont, with its limited capacity for irrigation from mountain streams and surfaces, is recognized as n, grazing district, bearing the nutritious buffalo grass, and roasonab}y traversed by streams.:._conditions only favorable to pastoral occupation ancht sparse popu­ lation.

Dnrin£>' 1867 the public attention was occupied by very favorable reports of the rnine~al resources of Now Mexico. The Kansas division of the Union Pacific raiJron,cl, while not relinquishing the policy of a direct western communication with Dem·er and Great Salt Lake City, determined to place a party in the field to explore a southwestern line from the junction of longitude 102° with latitude 39° to a crossing of the Rio Grande at Albuquerque, latitude 35°, longitude 0 lOG½ , nml'thcnco wostwardly through New Mexico, Arizona, and southern Cali­ fornia, on or near. the 35th parallel. The results of this exploration fully confirming the observa,tions of Lieutenant ..Whipple in 1853-'54, have established that gold, silver, and copper mines are as numerous :mcl va1uable as in Colorado;· and also that bods of lignite coal occur around tho western end of Raton mountain, and the neighboring foot-hills of tho Rocky mountains, while a formati911 of early cretaceous coal has been discovered in the valley of the Rio Grande. The first coal basin consists of an immense thickness of coarse sandstones, first manifesting themselves in some of the ravines of tho Raton, a,bout 20 miles east of Raton Pass, but soon becoming visible on the flanks of tho mountain, continuing through the pass, and to an unknown distance west of it. This formation lies nearly horizontally against the base of the Raton ancl Rocky mountains, extending the latter from the .Arkansas river at Ca,11011 City to the vallej of the Little Cimarron on the south. In the Raton Pass the coal beds, wbich ·n,re quite thin in the Manco del Barro Pass, lJcgin to assume importance. About six miles :fiirom Trinidad, a locality exhibits a tota,l thickness of about five foot of good coa,l, separated into four beds, placed near together. Near the top· of tho pass are also beds of the same thickness, but at the southern exit of the pass, in canons connected with upper waters of tho Canadian, there ca,llec1 Reel river, these beds occur in still greater magnitude, being eight feet thick. All these arc, however, of trifling nature compared with the great bet.ls found in the caflons of the V crmejo valley, which show in one locality 10 feet of coal in two beds, separated by 10 inches of slate. The same strata, were found on the other side of tho canon, one-half mile distant, !:tnd in other canons several miles westward. Further south other thinner beds were seen near V ermcjo of the thickness of three and four feet of good coal. Beyond tho Pcrnejo tlrn high table lands containing the co:11 beds disa,ppear entirely, aud tho only sedimentary rock in view is the early cretaceous sand stone, capped in places with middle creta,ceous limestone. As the high table ln,nc1 of tertiary sandstone extends north of the Raton, it is proba,bJe that similar beds exist in that direction. Coal has a,lso been discovered on the Rio Grande in ya,rions pb. cs above Picdras N egras, a,s well as below in the vicinity of Laredo, Gurrero, and R<tma,. t , 'l'he cfrcoYerics of gold-bea1ing quartz, first limited to the Greo·ory district, i~ 1olo1:ac1o, exten_ding :1bout 30 miles along the base of the Snowy range, from Gold ll1ll to Empue C1ty, now reach the southern limit of Colorado, and thence along the Sierra faclrc, following the general course of the valley of the Rio Iu 1 ~7, at Ch_icago an artesian ~vell, at tho depth of 1,190 feet, struck a subterranean tr_eam, 01gh_t foot m depth, an<l flowmg with a strong current, from which 600,000 gallons d'.1-1\y arc dcl1yerc~ at tho surface, and 450,000 gallons daily at an elevation of 45 feet.

  • A History of Tailings1
    A HISTORY OF MINERAL CONCENTRATION: A HISTORY OF TAILINGS1 by Timothy c. Richmond2 Abstract: The extraction of mineral values from the earth for beneficial use has been a human activity- since long before recorded history. Methodologies were little changed until the late 19th century. The nearly simultaneous developments of a method to produce steel of a uniform carbon content and the means to generate electrical power gave man the ability to process huge volumes of ores of ever decreasing purity. The tailings or waste products of mineral processing were traditionally discharged into adjacent streams, lakes, the sea or in piles on dry land. Their confinement apparently began in the early 20th century as a means for possible future mineral recovery, for the recycling of water in arid regions and/or in response to growing concerns for water pollution control. Additional Key Words: Mineral Beneficiation " ... for since Nature usually creates metals in an impure state, mixed with earth, stones, and solidified juices, it is necessary to separate most of these impurities from the ores as far as can be, and therefore I will now describe the methods by which the ores are sorted, broken with hammers, burnt, crushed with stamps, ground into powder, sifted, washed ..•.

E. "H"Street Baker Grants Pass *************************** MINING IN BAKER COUNTY, 1861 to 1959* By Norman S. Wagner** Introduction Baker County mining began with the discovery of gold in 'Griffin Gulch in 1861. This and the develop­ ment which followed at Auburn represent gold mining at its historic best. Since 1861, much water has flowed down the sluice boxes with respect to mineral resource development within the county. As a result, the dis­ covery story is left for historians to tell, and the following paragraphs are devoted to the high points of the many kinds of mining endeavors that occurred in Baker County between 1861 and 1959. Hydraulic and sluicing operations All of the earlier placer operations have one thing in common with Griffin Gulch and Auburn. This is that they were carried out by means of ground sluicing and hydraul icking, using generous amounts of hand labor. These means of handl ing placer ground continued in exclusive use throughout the first forty years of Baker County mining history. It wasn't until the present century that the more familiar bucket-line dredges and other kinds of mechanized digging and washing plants made their appearance. Even yet the old methods are still employed on a small scale in circumstances where ground conditions permit. The Rye Valley placers on Dixie Creek represent a notable example of an early discovery made shortly after 1862.
