The Iron King mine is about 2,000 feet west-northwest of the intersection of the 112 15 west meridian and the 34 30 north parallel in the Humboldt region in central Yavapai County, Arizona. The mine is approximately in the geographical center of the Humboldt region. Precambrian rocks form the bedrock. Late Cenozoic unconsolidated river wash and valley fill with some interbedded basalt locally mantle the Precambrian rocks, especially in the north-central part of the region. The Precambrian rocks consist of two metamorphosed volcanic formations and intrusive rocks that range in composition from quartz porphyry to gabbro. The volcanic formations originally were flows, volcanic breccias, and tuffaceous sedimentary rocks. Dynamothermal metamorphism of these rocks formed textures, structures, and mineral assemblages characteristic of low-grade ;riietamorphic rocks, but sufficient relict textures and structures remain to permit delineation of formations on the bases of their original nature. All the Precambrian rocks are foliated, except those in the interior parts of the larger intrusive masses. This foliation has two major trends, (1) north to N 20° W, and (2) N 20° E. The northeast-trending foliation is younger and locally is superimposed on the north- to northwest-trending foliation. The Precambrian rocks strike north to northwest and dip steeply, chiefly westward. Duplication of stratigraphic units and determination of tops suggest two major northeast-trending folds, which probably plunge southward. The northeast-trending foliation appears to bear an axial-plane relationship to these folds. Some masses of igneous rock probably were intruded during development of foliation. The Iron King deposit supports the only active mine in the Humboldt region. It consists of 12 steeply plunging echelon veins arranged along the footwall of a sheared and altered zone in the metamorphosed andesitic tuffaceous sedimentary rocks. Narrow zones of more intense shear probably localized the veins. Solutions first introduced quartz, pyrite, ankerite, and sericite, forming a sporadically mineralized zone (in the hanging wall of the deposit) and probably veins in the Iron King fracture system. Intra-mineralization shear strongly brecciated these early minerals and formed the structures that localized and distributed the ore minerals in the veins. After this deformation, sphalerite, galena, chalcopyrite, tennantite, arsenopyrite, pyrite, quartz, and ankerite were deposited; the last three minerals may have formed through solution and the redeposition of earlier minerals. Formation of sericite either accompanied or followed the deposition of ore-forming minerals. Silver is related closely in distribution to copper and probably is in the tennantite. Gold occurs chiefly in the pyrite. Banding, mimetic after foliation and planes developed by shearing, is pronounced in much of the vein material. Mineral zoning, generally similar in each vein, is a characteristic of the deposit. High-angle reverse faults of about 100 feet in maximum vertical separation offset the veins. These faults are nearly parallel to the veins in strike and dip.

The mine had been prospected intermittently for copper and zinc since 1,916, but there is no record that ore was produced. The country rock is pre-Cambrian granite containing many schist inclusions and narrow pegmatite dikes. Pitchblende disseminated in chlorite and sulfides was deposited in an obscure vein system during an intermediate stage of mineralization. This stage was preceded by biotitic alteration of amphiboles and sulfide deposition. The latest stage of mineralization is represented-by the limonitic dense quartz vein followed during mining. The uranium-bearing vein is about 2-3 feet wide and the dense quartz vein is less than 6 inches wide. Both veins are bordered by 1-3 feet of biotite- and sulfide-bearing granite and arriphibole schist. The uranium content of 26 samples taken in the mine and on the dump ranges from 0.002 to 1.40 percent. These samples contained as much as 2.97 percent copper and 5.96 percent zinc. The general outlook for further prospecting near the Copper King shaft is not favorable, because much of the 'immediately surrounding area has been thoroughly investigated without finding abnormal radioactivity. The most favorable environment for concentration of uranium minerals appears to have been in or near schist inclusions in granite, and further exploration in nearby prospects may result in the discovery of other uranium-bearing deposits. In the Copper King mine, additional exploration would aid in determining the extent of the uranium-bearing material.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Washington, D.C.","doi":"10.3133/tem128A","usgsCitation":"Granger, H.C., and King, R.U., 1951, Uranium in the Copper King Mine, Black Hawk No. 1 Claim, Larimer County, Colorado: U.S. Geological Survey Trace Elements Memorandum 128, Report: 22 p.; Plate: 24.34 inches x 10.77 inches, https://doi.org/10.3133/tem128A.","productDescription":"Report: 22 p.; Plate: 24.34 inches x 10.77 inches","additionalOnlineFiles":"Y","costCenters":[],"links":[{"id":8505,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/tem/0128-A/plate-3.pdf"},{"id":279188,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/tem/0128-A/report-thumb.jpg"},{"id":282978,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/tem/0128-A/report.pdf"}],"country":"United States","state":"Colorado","county":"Larimer County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -105.471840,40.836282 ], [ -105.471840,40.852449 ], [ -105.518789,40.852449 ], [ -105.518789,40.836282 ], [ -105.471840,40.836282 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"528c96bee4b0c629af44de0f","contributors":{"authors":[{"text":"Granger, Harry Clifford","contributorId":8832,"corporation":false,"usgs":true,"family":"Granger","given":"Harry","email":"","middleInitial":"Clifford","affiliations":[],"preferred":false,"id":285040,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"King, Robert Ugstad","contributorId":45696,"corporation":false,"usgs":true,"family":"King","given":"Robert","email":"","middleInitial":"Ugstad","affiliations":[],"preferred":false,"id":285041,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70221635,"text":"70221635 - 1951 - Ilmenite, magnetite, hematite, and copper in lavas of the Keweenawan series","interactions":[],"lastModifiedDate":"2021-06-25T20:15:53.994381","indexId":"70221635","displayToPublicDate":"1951-01-01T15:09:23","publicationYear":"1951","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1472,"text":"Economic Geology","active":true,"publicationSubtype":{"id":10}},"title":"Ilmenite, magnetite, hematite, and copper in lavas of the Keweenawan series","docAbstract":"The opaque minerals in ten lava flows of the Keweenawan series of Michigan were studied microscopically by the writer. The basaltic lavas, which range in thickness from 100 to 1,400 feet, contain ilmenite, magnetite, hematite, intergrowths of magnetite-ilmenite and ilmenite-hematite, copper sulfides, native copper, and pyrite. Variations of opaque iron minerals with thickness of flow are slight, but native copper predominates in the thinner flows and copper sulfides in the thickest. Pyrite occurs only in the thickest flow. Two groups of opaque minerals and their alteration products are distinguished. The earlier group includes magnetite, ilmenite, magnetite-ilmenite and ilmenite-hematite intergrowths, copper sulfides, and native copper. The later group includes hematite, native copper, chalcocite, pyrite, chlorite, and sphene. The second-generation minerals formed by the action of volatiles escaping from the lavas. The ratio of Ti to total Fe correlates with the degree of differentiation of the lavas, but the ratio of ferric to ferrous iron does not. The latter ratio was controlled primarily by the action of escaping volatiles.

During World War I, the Majuba Hill mine\nproduced about 4,000 tons of 12 percent copper ore, and during World\nWar II about 23,000 tons of ore containing 2 to 4 percent copper and\nenough tin ore to furnish from 10 to 15 tons of metallic tin. No\nuranium has been produced.
\nThe bedrock geology of Majuba Hill consists of a complex;\nvolcanic neck or plug composed of rhyolite porphyry, porphyritic\nrhyolite, quartz feldspar porphyry, breccia dikes, and irregular breccia\nmasses. This plug intruded Triassic (?) sedimentary rocks, chiefly shale.
\nThe principal loci of ore deposition were (l) parts of the\nbreccia bodies, particularly where they were porous and where they were\nsilicified and tourmalinized, and (2) a few small pre-mineral fractures\nadjacent to the breccia masses, Intense hydrothermal alteration resulted\nin the formation of sericite, quartz, and tourmaline in the wall rocks.\nThis was accompanied or followed by deposition of arsenopyrite, pyrite,\ncassiterite, fluorite, and several primary sulfide minerals of copper.
\nAll of the ore bodies exposed in the mine are highly oxidized,\nand a profusion of secondary minerals of copper and iron have been found.\nThe only uranium minerals detected are the phosphates torbernite and\nmatatorbernite and the arsenate zeunerite. These are widely disseminated\nthroughout the mine in small amounts associated with the secondary\nminerals of copper and iron along minor fault surfaces, bedding planes in\nthe shale, and in porous parts of the breccia. A primary uranium mineral\nhas not been found.
\nThe secondary uranium minerals appear to be most abundant\nwhere copper ore is highest grade. Although unoxidized uranium ore\nhas not been found, it is inferred from this relation that the deposition\nof the original uranium minerals favored those areas where primary copper\nmineralization was most intense. There may have been an intimate association\nof uranium with silver in the ore, but this has not been established.\nThe U3O8 content of samples of copper ore ranges from .0.002 to 0.30 percent.
\nBecause the bottom of the oxidized ore has not been reached in\nmining or exploration, the downward extensions of the known ore bodies\nof secondary minerals would appear to be worthy of investigation to determine\nthe grade and extent of the primary ore.

Hypogene sulfides, pyrite and chalcopyrite, were added during the process of alteration, accompanied in part by sericite. Molybdenite is younger than the chalcopyrite. Locally, the host rock was altered to a quartz-orthoclase-sericite facies containing more quartz and orthoclase than is found in the main alteration facies. Chemical analyses indicate that alteration and mineralization of the host rock resulted in loss of iron, lime, and soda, and addition of sulfur, copper, and potash.Supergene changes include the formation of a chalcocite blanket in late Pliocene or early Pleistocene time. Chalcocite replaced chalcopyrite in preference to pyrite. The chalcocite blanket is truncated by the present erosion surface and its distribution can be recognized from the character of the iron oxide left in the leached cavities. Along some of the fractures and faults, supergene clay is present, consisting of kaolinite and a member of the saponite-montmorillonite group.

This virgin deposit has a small outcrop and seems ideally suited for a geochemical study of the dispersion pattern produced by weathering in a desert climate. Samples of soils, alluvium, ground water, and vegetation were analyzed for copper. To avoid grinding, to accentuate differences in copper concentration, and to decrease sampling error, sampling was confined to the silt and clay fraction of the soil and alluvium. A sensitive field test for copper, using hydrochloric acid for a digestant and dithizone for copper determination, proved both quick and reliable.
The results of the study show that at present little copper from the ore body dissolves in the ground water or runoff, and also that very little is taken up by plants growing on the ore outcrop. For this reason, prospecting for similar deposits by the sampling and analysis of ground water or vegetation is unlikely to be fruitful. A study of plant ecology, however, shows that certain plant species grow preferentially on outcrops of copper ore and may be useful as indicators of ore.
Chrysocolla along joints carries most of the copper in the oxidized zone. The chrysocolla is slowly disintegrated mechanically as the rock weathers and enters the fine fraction of the soil. Slope wash and soil creep carry the copper along with the other soil materials into the nearby washes, where they are incorporated in the alluvium and swept downstream during floods. Abrasion probably continues to concentrate the copper in the fines, but the net change downstream is a decrease in copper content caused by dilution.
As copper can now be readily determined by chemical analysis in the field, analysis of soil and alluvium seems to be one of the best geochemical methods of prospecting for copper in a desert environment. Wherever appreciable copper is found in alluvium or soils, upstream or upslope sampling can be used to trace the copper back to its source.

Close scrutiny, however, generally reveals unexpected features at each mine.
For example, the Hitachi copper mine formerly segregated its developed ore reserve into positive and probable on the basis of the possibility of high-grade and low-grade production from individual stopes.
Tests were made by the writer at Hitachi on the accuracy of the original reserve estimates of a few ore blocks by comparing those figures with the final production data. The results suggesthat the average reserve estimate of positive ore may be accurate within 20 percent, plus or minus.
A ten-year supply of proved ore at the big mines is not unusual; hence Hitachi is not much concerned with the additional categories of probable and possible ore, unless the positive ore has become inaccessible because of caving of the workings. For the sake of comprehensiveness, however, the writer studied the assay maps and stope maps in collaboration with the mine management and estimated tonnages of probable and possible ore, qualified by lower reliability ratings. Exploration prospects also were described in actual figures, subject to a variation of plus-or-minus 75 percent.

Because this reconnaissance work indicated that bedrock might be relatively near the surface over an extensive area where cuttings were to be made, a more detailed seismic study of the area was made in November 1949.

Since the war, work in this field has been undertaken by several independent groups in the United States and Canada, including the Geochemical Prospecting Unit of the U. S. Geological Survey.Best results have been obtained by systematic analysis of zinc in residuum, ground water, and vegetation; copper and lead in gossan and residuum; tin in residuum and alluvium; molybdenum in residuum; and cobalt, nickel, and gold in vegetation. In addition, studies of plant ecologies and toxicity symptoms in vegetation in relation to metal-rich soil appear to be promising.Rapid colorimetric and spectrographic tests for traces of metals in soil, water, and vegetation have been developed for use under field conditions.

The use of copper sulphate is not without danger because of variation in toxicity according to the hardness of the particular water supply; also, the toxicity and efficacy of Roccal have varied considerably in different lots. Neither copper sulphate nor Roccal will cure in one treatcent a well-established epizootic of bacterial gill disease. For these reasons, a series of new disinfectants has been tested in the laboratory in an attempt to find a more effective cure and preventive for bacterial Eill disease. One of these tested, pyridylmercuric acetate, was suggested by Wan Horn and Katz (1946).
