THE MINING DISTRICTS OF THE WESTERN 

UNITED STATES.

PART I. GEOLOGIC INTRODUCTION.

By WALDEMAE LINDGREN.

ORIGIN AND SCOPE OF THIS WORK.

The mining districts of the Western or Cordilleran States are 

numerous and scattered over wide areas. The first attempt to locate 

all of them on.a single map was carried out by the writer in 1907, 

with the aid of Mr. J. M. Hill and the statisticians in charge of the 

offices of the Survey at Denver, Salt Lake City, and San Francisco 

(Messrs. Chester Naramore, V. C. Heikes, and C. G. Yale). This map 

of the Western States was included in the annual volume of Mineral 

Resources of the United States. The large area covered and the 

necessity of adding explanatory tables made this map cumbersome 

to handle. When a revision was decided upon in 1910 and assigned 

to Mr. J. M. Hill, it was found advisable to map the several States 

separately and publish the maps, with more extensive explanatory 

text, in the convenient form of a bulletin.

At the outset not a little difficulty was experienced in the definition of the mining districts and in deciding their proper names and 

extent. Mineral deposits rarely appear singly; on the contrary, a 

number of them usually cluster in certain localities. In general in 

the Western States, when such a mineralized area is discovered and 

locations have been made, a miners' meeting is called, regulations 

are adopted beyond the simple statutory laws of the Federal and 

State governments, the limits of the district are defined, and a name 

is given to it. For many districts these limits are uncertain and vague 

and can not always be ascertained, though the data are supposed to 

be on file with the county authorities. The name does not always 

correspond with that of the locality; for instance, the mining district

5

surrounding Butte, Mont., is called Summit Valley. At many places 

little attention has been given to these legal districts and the original 

area has by common consent been subdivided into several more or 

less definite subdistricts. The real reason for the adoption of mining 

districts is to have an easily accessible record of claims, for, as is well 

known, the Federal authorities keep no list of claims located, and this 

duty is relegated to the recorder of each district.

In California, except in the desert region, few well-defined mining 

districts exist, and each center of mining operations has been given a 

geographic name appropriate to the locality.

It is impossible, therefore, to apply the term "mining district" 

consistently, but in the present work wherever practicable the local 

designations and rules have been followed. A large mineralized area 

is designated as a mining region; for instance, the "San Juan region/' 

embracing the mountainous area of southwestern Colorado. The 

mining region consists of a number of mining districts. These vary 

greatly in size, but such a representative unit would perhaps include 

from 12 to 36 square miles. Many districts are informally subdivided 

into smaller units, referred to as "camps," but as a rule the camps 

can not be shown owing to the small scale of the map.

DISTRIBUTION OF MINING DISTRICTS.

IRREGULARITY.

In order to show comprehensively the distribution of the districts 

they have been represented on a smaller-scale map of the Western 

States (fig. 1). The first impression is that of irregular distribution, 

a clustering at some places, a scattering at others, with certain areas 

almost devoid of mineral deposits. Except along the Pacific coast 

in California there is little evidence of any arrangement in regular 

zones or " belts."

The most easterly indications of the metallic wealth of the Cordillera are found in western Texas and Oklahoma, where copper ores 

are thinly scattered through certain "Penno-Carboniferous" sandstones. Slightly farther west rise small groups of mountains, sentinels in front of the Kocky Mountains, such as the Black Hills of South 

Dakota, the Little Rockies of Montana, or some of the short ranges 

of western Texas; these contain some ore deposits.

The most westerly districts lie in the Coast Range of California, 

which contains quicksilver ores, and along the beaches of Oregon and 

Washington, where the sands yield gold and platinum.

There are several notable "blanks" on the map where mining 

districts are almost absent. One of these occupies areas in Oregon 

and Washington. Another barren area embraces parts of Utah, 

Arizona, New Mexico, and Colorado.
GEOLOGIC INTRODUCTION. 7 

DISTRIBUTION IN RELATION TO GEOLOGIC STRUCTURE.

As the deposits of metallic ores are the results of geologic processes, 

there is necessarily a close connection between the geologic structure 

and the mineralization of an area. On a map of the scale of figure 1

it is scarcely possible to bring out these relations clearly, especially 

where the structure is complicated. The first broad principle which 

holds for the Cordilleran region is that where the rocks lie horizontal 

and no disturbance has taken place ore deposits are rare, poor, or
8 MINING DISTRICTS OF WESTERN UNITED STATES.

absent. The last is of course true for alluvial areas like that of the 

Sacramento Valley in California. Few- mining districts are found in 

the vast plateau province of southern and eastern Utah, western 

Colorado, northern Arizona, and western New Mexico, already 

referred to; this barren area also extends into western and central 

Wyoming. In this great province the sediments, ranging in age from 

Cambrian to Eocene, lie in horizontal position almost unbroken by 

mountain-building disturbances. An analogous condition exists iii 

the enormous areas in the Northwest, in Oregon and Washington, 

with extensions into southern Idaho, Nevada, and California. Here 

flows of igneous rocks, mainly basalts of Tertiary to early Quaternary 

age, together with tuffs and lake beds, cover the country, and few 

traces of mineralization are found in them.

As a rule the deposits occur in mountain ranges, but here again it 

is necessary to draw a distinction, for many of the most conspicuous 

and highest ranges are almost void of metallic ores. Among wellknown instances of this barrenness are the high Sierras of California, 

the Cascade Mountains of southwestern Washington, the Front 

Range of Colorado, the Bitterroot Range of Montana and Idaho, and 

finally the Wind River and Teton ranges of Wyoming. It is clear, 

then, that mere uplift, faulting, and crushing, and attendant circulation of atmospheric water are not sufficient to produce metal deposits. 

The ranges just enumerated consist either of enormous areas of 

mountainous intrusive rocks of post-Jurassic age, or of Tertiary lava 

flows and volcanoes, or of pre-Cambrian granite and gneiss.

Nor is it common to find rich deposits within ranges composed 

exclusively of folded and faulted sedimentary rocks. The most 

characteristic occurrence of important metal deposits is where intrusive masses of moderate size have broken through the sedimentary 

series; as a rule the sediments are of Paleozoic age and the intrusive 

rocks are granites, diorites, and monzonite of Cretaceous or Tertiary 

age. In all such deposits the metallization appears to have taken 

place shortly after the intrusion. The deposits may develop either 

in the sedimentary rock or in the igneous rock, and they have been 

laid bare by deep erosion of the rocks overlying them.

In another less common kind of deposit the ores are contained in 

lavas of- Tertiary age and may be of great richness. The igneous 

rocks in this case are usually flows of andesite or rhyolite. These 

deposits occur in regions like Nevada, where there have been eruptions from many local vents and where the rocks have been extensively 

decomposed by solution and gases of volcanic origin. Many of these 

deposits have suffered little erosion since their formation, which 

followed closely the end of the epoch of eruptions.

There are many other kinds of deposits, but those mentioned are the 

sources of the largest part of the metallic production of the West.
GEOLOGIC1 INTEODUCTIOET. 9

FORM AND CONTENT.

The form of the deposits is manifold and depends on the spaces 

provided for their reception or on the manner in which they made 

place for themselves. Practically all of them were formed by deposition from water solutions, usually ascending hot water, and as the 

path of such waters commonly follows fissures the resulting* deposits 

are in large part fissure veins. The walls of the fissures were soaked 

by the solutions and ores were deposited in them. Some rocks like 

limestone are peculiarly susceptible to chemical alteration, and where 

traversing such rocks the mineralizing solutions spread far and wide, 

causing the deposition of metallic ores. Such occurrences are called 

replacement deposits.

The ore minerals were in the first place sulphides of the baser 

metals, such as galena, pyrite, or zinc blende, or more rarely oxides 

such as magnetite. Gold alone has originally been deposited, as 

native metal;'more rarely it is combined with tellurium. Through 

the oxygen of surface waters the sulphides have usually been oxidized 

to various other compounds such as cerusite, hematite, and calamine; 

this so-called oxidized zone ordinarily reaches down to the permanent 

water level and in some places considerably below it. In regions of 

heavy precipitation the oxidized zone is thin. Where there is little 

rainfall the water level lies far below the surface. Within the Cordilleran region the water level is rarely more than a few hundred feet 

below the surface; in exceptional places such as Tintic, Utah, it may 

exceed 2,200 feet in depth.

The ores of the oxidized zone are, as a rule, richer than the underlying sulphides. Just below the oxidized belt secondary sulphides 

may be formed through concentration by descending surface waters 

and this part of the deposit is likely to be exceptionally rich. Such ' 

secondary sulphides are chalcocite or copper glance and various rich 

silver minerals. In many copper deposits, such as those at Ely, Nev., 

and Miami and Ray, Ariz., the only workable part of the deposits 

consists of a layer of this secondary copper glance. In silver veins 

no such sharp division between the two zones is found. Much of the 

richest ore mined near the surface in the Cordilleran region is the 

result of secondary enrichment by descending waters.

CLASSIFICATION OF DEPOSITS.

The first broad division that can be established among the mineral 

deposits of the West is between those of pre-Cambrian and postCambrian age. As a matter of fact the latter are almost wholly postJurassic and a large majority are post-Cretaceous.

PRE-CAMBRIAN DEPOSITS.

The ores of pre-Cambrian age were formed before the earliest 

Cambrian sediments were laid down in the Paleozoic seas which
10 MINING DISTRICTS OF WESTERN UNITED STATES.

covered a large part of the Cordilleran region. They had then been 

subjected to considerable erosion and therefore only the deep-seated 

deposits are now exposed. They are of many different kinds, but 

it is believed that they were mainly the result of after action of preCambrian intrusions or were leached from old rocks by hot waters at 

considerable depth. The rocks in which they are contained are 

mainly granites, gneisses, and schists of various kinds; most commonly the ores are inclosed in amphibolite, diorite, or gabbro. The 

mere fact that ores4 occur in pre-Cambrian rocks is not enough to 

establish their age, for deposition could have been effected in these 

rocks during subsequent periods. They are in places directly overlain by Paleozoic sediments, and this of course constitutes a good 

proof of the age of the ore deposits. The pre-Cambrian rocks have 

usually participated in and been pressed by dynamometamorphic 

processes and are now schistose. This is another criterion, for except 

along the Pacific coast in California, Oregon, Washington, and western 

Nevada, there has been no regional metamorphism in the Cordilleran 

region since pre-Cambrian time. The association of the ore minerals 

with heavy silicates such as garnet and tourmaline is common in preCambrian deposits, though such an association is also found in deposits 

formed during later' epochs of metallization*

The pre-Cambrian deposits include segregations in igneous magmas, 

such as those of Iron Mountain, in Wyoming, but this type is rare. 

More common are irregular fissure veins and disseminations in schist. 

The metal contained is mainly copper in the form of chalcopyrite, 

with small amounts of gold and silver; lead deposits are of rare 

occurrence,

As the pre-Cambrian rocks are largely covered by younger sediments and igneous rocks, these ancient deposits are very irregularly 

distributed and do not form distinct belts or zones. They occur in 

South Dakota, Wyoming, Colorado, New Mexico, and Arizona; 

probably also in southwestern California. Compared to the later 

deposits they are on the whole poor.

POST-CAMBRIAN DEPOSITS.

The deposits formed later than the earliest Paleozoic sediments 

may be divided into two groups (1) those contained in sedimentary 

rocks with no traceable connection with igneous rocks; (2) those 

occurring in igneous rocks, or in the sedimentary rocks surrounding 

them.

DEPOSITS IN SEDIMENTARY ROCKS.

The first group is much the smaller one. Aside from some poor 

and irregular deposits of copper and lead in limestone for instance, 

in northeastern Utah and adjacent parts of Idaho the origin-of 

which is in doubt, this group consists of the widespread copper ores
GEOLOGIC INTBODUCTION. 11

in sandstone found in Oklahoma, Texas, New Mexico, Colorado, 

Arizona, Utah, and Idaho. The ores are disseminated in Jurassic, 

Triassic, or Carboniferous sandstones, and the most prominent ore 

mineral below the zone of oxidation consists of chalcocite. In western Colorado and eastern Utah these sandstones also contain vanadium 

and uranium minerals. Successful exploitation has been carried on 

at some places, but on the whole the deposits are poor. The metals 

sparsely disseminated as salts in the sedimentary rocks are believed 

to have been leached by surface waters. The concentration has 

probably proceeded since an active water circulation was established 

in these strata that is, since the beginning of the Tertiary.

DEPOSITS CONNECTED WITH IGNEOUS BOCKS.

The large group of deposits connected with igneous rocks yields 

 almost the whole of the Cordilleran production. Practically all the 

deposits are post-Jurassic, for in the Kocky Mountain region the 

Paleozoic and the larger part of the Mesozoic were eras of quiet 

sedimentation. Only along the Pacific coast, in the Sierra Nevada, 

do we find evidence of Paleozoic eruptions, which were mostly surface 

flows, and it is not impossible that a few ore deposits in that region 

may be found to be of Paleozoic age. During Triassic and Jurassic 

time eruptions of basic lava took place in California, Oregon, and 

western Nevada, and it is possible that they were closely followed 

by some metallization. The only definite evidence of this kind is 

from southeastern Oregon, where the Triassic or Jurassic basic flows 

east of Baker City, on Powder River, contain chalcocite and native 

copper in connection with zeolites, calcite, and epidote.

At the end of the Jurassic period or in the earliest part of the 

Cretaceous an era of igneous activity began in the Cordilleran region, 

which culminated in the middle of the Tertiary and continued in sporadic outbursts up to a comparatively recent time. Small eruptions 

are believed to have taken place near Lassen Peak, in northern California, within the last 200 years. Most of the ore deposits now worked 

in the Western States were formed within this era of volcanism.

Geologic evidence has shown .that each epoch of eruptions was 

followed by a more or less intense mineralization, consisting in the 

development of ore minerals by the filling of fissures or by the replacement of the rocks themselves in or about the igneous rocks.

Volcanism manifests itself by the eruption of lavas at the surface 

and by the intrusion of magmas into deeper portions of the crust. 

The lavas, cooling quickly, usually consolidate as fine-grained porphyritic rocks, commonly containing more or less of a glassy base; 

the intrusive magmas, cooling slowly and under pressure, result in 

coarser-grained granular or porphyritic rocks without a glassy base. 

As the intrusions take place at a considerable depth, it is clear that
12 MINING DISTRICTS OF WESTEBN UNITED STATES.

such masses and the ore deposits which may accompany them will 

not be exposed at the surface unless it happens that the region has 

been subjected to deep erosion. The eruption of lava flows at the 

surface is no doubt usually accompanied by intrusions underneath 

them, and there is likewise little doubt that the great masses of postJurassic intrusions were accompanied by now eroded lava flows. In 

the San Juan region of southwestern Colorado, at Tintic, Utah, and 

at some other places erosion has exposed the intrusive bodies below 

the earlier Tertiary lava flows.

The mineral deposits formed at considerable depth in and around 

intrusive masses differ both structurally and mineralogically from 

those formed near the surface, though it is possible, and in fact 

likely, that the latter may be the upper parts of a deeper body of 

mineralized rock and that they would be found to change then* character if they could be followed to great depths. Therefore, though a. 

distinction must be made between the two classes, there are intermediate forms and probably no radical genetic difference.

The oldest intrusions are the great early Cretaceous granitic 

batholiths of the Sierra Nevada, extending northward into British 

Columbia and Alaska. Less extensive intrusive masses of the same 

age are found in Oregon, Nevada, and Arizona, but on the whole 

toward the east such masses are less conspicuous and smaller and 

date from a later time. Most of the relatively small granitic and 

monzonitic stocks of Colorado and New'Mexico are probably of latest 

Cretaceouk or earliest Tertiary age. After they had been exposed 

by erosion, the middle Tertiary lavas in many places covered then* 

outcrops. \

The volcanic flows which cover large areas in the Western States 

are generally of Tertiary age, ranging from Eocene to latest Pliocene, 

though the latter are mainly nonproductive basalts. The productive 

areas are mostly in Eocene or Miocene flows of andesite or rhyolite. 

Late Cretaceous lavas occur in Montana and Colorado, but so far as 

known they contain few mineral deposits. Although mineralization, 

more or less intense, is the rule in the vicinity of. intrusive bodies, 

especially those of moderate or small, size, it is rather exceptional in 

the lava flows and enormous areas of them show no trace of metallic 

ores.

From the relations explained above it follows that the deposits in 

or near intrusive bodies are apt to be of greater age than those in the 

more recent lava flows; on the whole their age ranges from the earliest 

Cretaceous to the earliest Tertiary. Among the occurrences are the 

gold-quartz veins of the Sierra Nevada and Oregon and many similar 

deposits hi Nevada; the gold, silver, and base-metal deposits extending from Leadville to Boulder, in Colorado, and the similar deposits in 

the great batholiths of central Idaho and western Montana and at
GEOLOGIC INTRODUCTION. 13

many places in Arizona, for instance near Kingman and Frescott; 

and the copper deposits of Clifton, Globe, and Bisbee, in Arizona; 

of Ely, in Nevada; and of Bingham, in Utah. The deposits may take 

the form of contact-metamorphic bodies, which usually carry copper 

and zinc, more rarely lead; or replacement deposits of lead ores some 

distance away from the intrusive contacts; or normal veins and shear 

zones with simple sulphides of the base metals, carrying more or less 

gold and silver; or of native gold or irregular disseminations of sulphides in altered igneous rocks. Very commonly all these modifications occur in the same district and form what has been termed a 

metallic aureole around the intrusive rock. Structurally the veins 

are likely to be clear cut and well defined, with regular strike and dip. 

The filling is massive and drusy structure is less common than in the 

veins formed near the surface, the principal gangue mineral being a 

milky quartz.

The deposits formed near the surface and usually appearing in 

volcanic flow rocks are almost exclusively veins or disseminations; 

most of the productive occurrences are typical veins. As the rocks 

are more extensively shattered near the surface than at greater depths, 

many wide areas of volcanic rock are deeply altered by ore-bearing 

solutions and transformed into quartzose, sericitic, or kaolinitic masses 

or less completely altered to greenish "propylite" by the development of chlorite and pyrite. The gangue of many deposits contains 

calcite, barite, and fluorite in addition to the common usually finegrained and locally chalcedonic quartz. The structure of the veins 

is likely to be irregular, brecciated, and drusy. These veins, many of 

which are exceedingly rich, carry mainly native gold in fine distribution, rarely coarse, often alloyed with much silver; also argentite and 

various silver antimonites and arsenites.

Base metals are ordinarily not abundant in the deposits formed 

near the surface. These deposits occur in Nevada, Washington, 

Idaho, Colorado, New Mexico, Utah, and Arizona, but Nevada contains more of them than any other State. As examples may be cited, 

in Nevada the Comstock, Tonopah, Bullfrog, Tuscarora, Rawhide, 

Fairview, and National veins, as well as the more irregular deposits 

of Goldfield; in Washington, the Monte Cristo and Republic veins; 

in Idaho, the Custer and Silver City veins; in Colorado, the Cripple 

Creek and Silver Cliff veins; in New Mexico, the Mogollon veins; in 

Arizona, the veins of the Black Range, near Colorado River; and in 

Utah, the veins of the Mount Baldy district, near Richfield and 

Marysvale. The veins of the San Juan region in Colorado are found 

in a deeply dissected volcanic dome or plateau and some of the 

types here occurring are unusually rich in lead, copper, and zinc.

LOCAL GEOLOGY OF WESTERN ORE DEPOSITS.

ARIZONA.

The valuable ore deposits of Arizona are confined mainly to the 

southwestern part of the State. The portion which lies northeast 

of a line drawn from a point a little north of Clifton to Peach Springs 

and thence in the same direction to the Nevada line is covered by 

the horizontal beds of the plateau province or by lavas and contains 

only a few and unimportant copper deposits in sedimentary rocks. 

Wherever, as in parts of the canyon of Colorado River, the preCambrian crystalline rocks are exposed, mineral deposits may be 

found, though the prospects thus far uncovered do not indicate strong 

metallization.

The southwestern and larger part of the State is characterized 

by ore deposits of great variety and abundance, scattered irregularly 

through detached ranges rising above desert plains. No mineral 

belts of great persistence and length can be traced.

The ranges of Arizona are of manifold structure and composition. 

In the eastern half of the mineral-bearing area there is as a rule a 

succession of several thousand feet of Paleozoic rocks ranging from 

Cambrian to Carboniferous, which rest on a pre-Cambrian basement 

that is in many places exposed. In the extreme southeast Cretaceous rocks are also present, though rarely mineralized. Toward 

the west the exposures of pre-Cambrian schist increase in area and 

a large number of ranges west of the one hundred and twelfth meridian are whoUy built up of such rocks, locally intruded by monzonites 

or covered by Tertiary lavas.

The geologic section of the Paleozoic and Mesozoic rocks varies 

considerably in different parts of the State. At Bisbee, in the southeast corner, the Cambrian consists of 430 feet of quartzite overlain 

by 770 feet of limestone. The Carboniferous includes both Mississippian limestone 700 feet thick and heavy beds of Pennsylvanian 

limestone, of which 3,000 feet are exposed. The Cretaceous (Comanche) formations aggregate 4,500 feet in thickness. Farther 

north, near Clifton, the total thickness of the Paleozoic and later 

rocks is very much less.

Pre-Cambrian deposits of several types containing copper, gold, 

and silver are found in the districts adjoining Colorado River, near 

Parker, which is south of Williams Fork, and probably at other 

places farther south, in the little-explored country in Yuma County. 

They also appear in the crystalline schists of Yavapai County, and 

it has been suggested l that the great ^copper deposit of the United 

Verde mine at Jerome, which is contained in amphibolitic schists, 

also belongs to this class. Deposits connected with granular intrul Graton, L. C., Mineral Resources U. S. for 1907, pt. 1, TJ. S. Geol. Survey, 1908, p. 597.
GEOLOGIC INTEODUCTI01T. 15

sive rocks of Mesozoic or early Tertiary age are abundant in all 

parts of the region and consist of veins, contact-metamorphic deposits, and replacement deposits in limestone away from the immediate 

vicinity of igneous rocks.

Contact-metamorphic deposits in zones of garnet and other 

silicates adjoining intrusive rocks are particularly abundant, and as 

exceUent examples may be mentioned those of the Clifton, Bisbee, 

Saddle Mountain, Twin Buttes, Silver Bell, and Washington districts. The gold-bearing veins of Yavapai County are probably of 

Mesozoic age and appear around smaUer monzonite intrusions in 

pre-Cambrian schists. The veins near Kingman are likewise associated with intrusions of porphyry in pre-Cambrian schist. Copper, 

gold, silver, lead, and zinc are the principal metals found in the 

veins of these classes, but tungsten and molybdenum also occur. 

Chalcocite blanket deposits, due to concentration of lean primary 

disseminations by descending surface waters, connected with the 

same epochs of mineralization are mined at Clifton, Ray, and Globe, 

and prospected at a number of other places.

The deposits of the late Tertiary epoch are generally veins and are 

contained in rhyolitic and andesitic lavas; they are widely scattered, the most prominent examples being those of the Black 

Range, along Colorado River north of Needles, where the noted Gold 

Road mine is situated. Similar veins occur in the Kofa district, 

Yuma County; in the Mammoth district, Final County; and at some 

places in the Santa Rita Range, Santa Cruz County. The well-known 

Commonwealth mine, in the Pearce district, Cochise County, also 

belongs to the same class. .These veins generally carry gold and 

silver, but in places also copper, lead, and molybdenum. Placers 

are known principally in regions of metaUic aureoles around intrusions of granular rocks, but they can rarely be worked, on account 

of the scarcity of water; dry washing is often resorted to on a small 

scale. Among the best-known placer regions are those of Yuma 

and La.Paz, along Colorado River; Red Hill, in Yavapai County; 

Quijotoa and Greaterville, in Pima County; and Dos Cabezas, in 

Cochise County.

After this general review the individual ranges and their mineralization may be briefly mentioned.

The southeastern mountains, including the Peloncillo', Chiricahua, 

and Pinaleno ranges, are not rich in valuable deposits, though 

mineralized at several points, notably at Dos Cabezas and Paradise. 

The well-known copper deposits of the Clifton-Morenci district are 

situated near the New Mexico line, near the southern boundary of 

the plateau province, but in no distinct structural range.

Next to the west, in Cochise and Graham counties, follow from 

south to north the Mule Pass and Dragoon ranges, both strongly 

mineralized and containing many types of deposits, most prominent
16 MINING DISTRICTS OF WESTEBN UNITED STATES.

among which are the contact-metamorphic copper deposits of Bisbee 

(Warren district) and the gold-silver-lead replacement deposits of 

Tombstone. The Dragoon Range and its foothills have gold-silver 

deposits in lavas at Pearce and contact-metamorphic and replacement 

deposits at Dragoon, Turquoise, and Courtland. To the northnorthwest these ranges are continued by the Galiuro Mountains, 

which contain copper deposits at Copper Creek and undeveloped gold 

deposits in rhyolite. Still farther to the north-northwest, in Gila 

County and adjoining parts of Final County, are the veins and blanket 

deposits of copper ores at Globe, in a region of general uplift in which 

the range structure is less well defined. At short distances west and 

south of Globe are a number of contact-metamorphic copper deposits, 

among which the Saddle Mountain is the most prominent; also the 

chalcocite blankets of Ray and the now worked-out silver mine of 

Silver Bang.

The next tier of mountains begins at the Mexican line with the 

Huachuca and Canelo ranges, neither of which contains important 

mines. Just west of the Canelo He the Patagonia and Santa Rita 

ranges, both of which are strongly mineralized and show deposits of 

many kinds. Contact-metamorphic copper deposits are found at 

Washington and Helvetia, here and there accompanied by chalcocite 

deposits. Silver deposits in andesite occur in the Harshaw district 

and mixed ores in rhyolite in the same vicinity; lead ores occur as 

replacements of limestone at the Mo wry mines.

North of the Santa Rita extends the rugged Santa Catalina Range, 

with few valuable deposits; at its northern foot, in the San Pedro 

Valley, lies the Mammoth district, with gold-molybdenum ores in 

rhyolite.

West of Tucson and Santa Cruz River, in Pima, Pinal, Maricopa, 

and Yuma counties; the desert plains become more prominent. 

Numerous short ranges rise above the plains and are flanked by 

sloping alluvial fans. The region is extremely arid. Some of these 

ranges, especially those toward the west, contain only pre-Cambrian 

rocks. Others are built up of Paleozoic folded and faulted sediments 

with intrusive Mesozoic granitic rocks. Still others are composed 

mainly .of Tertiary flow rocks. Among the more prominent deposits 

in Pima County may be mentioned the contact-metamorphic copper 

deposits of Twin Buttes and Silver Bell and the gold-bearing veins of 

Quijotoa, said to occur in Tertiary lavas. In the extreme western 

part of the county are the little-known districts of Ajo, Growler, and 

Gunsight, in which copper ores are said to occur in contact-metamorphic deposits.

In Yuma County there are also a considerable number of low desert 

ranges containing some mining districts. The gold-bearing vein of 

the Fortuna- district, said to be in gneissoid rock, is southeast of
GEOLOGIC INTRODUCTION. 17

Yuma; the lead ores of Castle Dome are in a detached range northeast 

of Yuma. Farther away in the same direction are the gold-silver 

mines of Kofa, which are worked on vein deposits in Tertiary lava 

flows.

In the northern part of Yuma County the ranges are mainly of preCambrian crystalline rocks. In the Harcuvar and Harquahala 

ranges intrusions of probably Mesozoic granite have caused con-- 

siderable mineralization and the development of gold-bearing quartz 

veins, the best known district being that of Harquahala. A little 

farther east, in Maricopa County, also in a small desert range, lies the 

well-known gold deposit of the Vulture mine.

In the central portion of the State, in Yavapai County, rise a group 

of mountains, the most prominent of which are known as the Bradshaw Range. In this region cluster a great number of deposits of 

gold, silver, and copper. Among the gold mines the Congress is the 

best known, and the copper deposit of the United Verde is situated 

in the same region.

The mining districts in Mohave County comprise those of the 

Cerbat, Black, and Hualpai ranges, all of which trend north and 

south. The Black Range is continued north of Colorado 'River for 

some distance into Nevada. The Cerbat ores are mainly base metals 

associated with lead, zinc, and copper and differ greatly from the 

more recent gold veins of the Black Range, which outcrop in Tertiary 

lavas.

CALIFORNIA.

The dependence of mineral belts on geologic structure is particularly well marked in California.

Along the Pacific coast, from the vicinity of Santa Barbara to 

Humboldt County, rise the Coast Ranges, most recent of the great 

structural features of the State. They are largely built up of folded 

and crushed Cretaceous, Jurassic, and Tertiary sediments, in places 

broken through by andesite and basalt, and an older series of diabasic 

and serpentinoid rocks. The Coast Ranges are singularly poor in 

deposits of the ordinary metals, but a persistent belt of quicksilver 

ores follows them throughout and reaches its greatest development 

just north and south of San Francisco Bay. The quicksilver deposits 

are of late Tertiary or Quaternary age and seem to have been formed 

shortly after the eruption of basalt and andesite. The ores were 

formed near the surface and in all probability by hot ascending 

springs, of which the Coast Range,contains a great number. The 

gangue usually contains much opal. Among the best-known districts are those of the Clear Lake region and those of New Almaden 

and New Idria, in Santa Clara and San Benito counties.

To the east of the central valleys and separating them from the 

Great Basin lies the long and imposing mountain block of the Sierra

18 MINING DISTRICTS OF WESTERN UNITED STATES.

Nevada. Geologically it consists of clayey and sandy sediments, 

ranging from earlier Paleozoic to later Jurassic in age, closely folded 

and forming a belt along the western part that greatly increases in 

width toward the north. In early Cretaceous time these sediments 

were intruded by enormous masses of granitic rocks, mainly granodiorite, which since the late Cretaceous and Tertiary movements 

along the eastern border of the range form a zone that is of moderate 

extent in the northern part, but widens toward the south until in 

Tulare and Kern counties the intrusive rocks form nearly the whole 

range.

The gold belt of California, a succession of deposits of unusual persistence, begins as a narrow fringe.along the foot of the Sierra Nevada 

in Tulare and Kern counties, but widens greatly toward the north, 

and in Butte and Plumas counties is over 60 miles broad. Along this 

belt are located a great number of well-known mining districts. In 

the southern counties from Eldorado to Mariposa it contains the 

numerous and strong veins of the Mother Lode region, on which 

a number, of well-known mines are being worked. The Kennedy, 

with a depth of 3,600 feet, is the deepest mine in California. Farther 

north, in Nevada County, the celebrated Nevada City and Grass 

Valley districts are situated within this belt. Placer deposits 

abound throughout the gold belt, having accumulated along the 

present rivers and in the far older Tertiary gravels now exposed as 

erosion remnants high up above the canyons; in part the Tertiary 

gravels are covered by andesite and rhyolite, likewise of Tertiary age 

but without evidence of mineralization. The Tertiary gravels are 

still mined at many places by hydraulic or drifting methods. The 

Quaternary gravels at the foot of the range are now mined extensively 

by dredging at Oroville, Marysville, Folsom, and several points in 

Calaveras County.

The primary gold deposits, as distinguished from the secondary 

placers derived from their destruction by erosion, are for the most 

part quartz veins containing free gold. They were formed shortly 

after the intrusion of smaller masses of granite, granodiorite, gabbro, 

and peridotite into the sedimentary series, probably in early Cretaceous time.

The parts of the veins now exposed give evidence of having been 

deposited at considerable depth. Many thousand feet of overlying 

rock masses, together with the former outcrops of the veins, have 

been removed by erosion. Toward the north, in Tehama, northern 

Plumas, and Lassen counties, the gold belt is covered by a broad 

tongue of Tertiary volcanic rocks. Equally abruptly it emerges 

from this mantle above Redding and continues northward to the 

Oregon line, its width being from 50 to 60 miles. In this area, comprising parts of Shasta, Trinity, and Siskiyou counties and generally
GEOLOGIC INTRODUCTION. 19

known as the Klamath Mountains, gold-bearing veins and piacers are 

widely distributed. The placers have been the more productive. The 

richest veins occur in the Coffee Creek region. Hydraulic mining is 

still actively pursued along Klamath River and in the older Tertiary 

gravels. The deposits and their geologic conditions are similar to 

those of the Sierra Nevada.

Toward the south end of the State gold-quartz veins, probably of 

about the same age as those of central California, appear in San 

Diego, Riverside, and Los Angeles counties, in the mountains which 

form the continuation of the Sierra of Lower California. Except 

in San Diego, where the formerly productive Banner and Julian districts are located, the output from these deposits has been small. 

The veins occur in or near masses of metamorphic schist, which lie 

embedded in granitic rock.

A less well-defined belt of copper-bearing deposits follows the foothills of the Sierra Nevada and continues toward the north-northwest 

into the Klamath Mountains. Deposits of economic value have been 

found in Calaveras County at Copperopolis and Campo Seco; in Placer 

County at Dairy Farm; in Nevada County at Spenceville; and at 

several other places. At present the most important copper mines 

are those at Keswick and Bully Hill, in Shasta County. Copper 

deposits are also found in the northern part of Siskiyou County, near 

the Oregon line. The copper deposits as a rule occur in connection 

with igneous rocks, including both basic rocks like the diabase porphyries and Mesozoic andesites of the Sierra Nevada and acidic 

rocks like the alaskite porphyry of Shasta County. In places they 

also occur in genetic connection with peridotite and gabbro. They 

appear to have been formed a little earlier than the gold-bearing 

quartz veins in late Jurassic or earliest Cretaceous time, at considerable depths below the surface. Some of the smaller copper deposits, 

however, probably resulted from concentration by deep water from 

the surrounding rocks. All these deposits carry chalcopyrite with 

pyrite; only exceptionally is chalcocite present.

That part of California which lies to the east of the Sierra Nevada 

and the Peninsular Range is very different from the rest of the State. 

It is an arid region with detached ranges, generally trending northward; geologically it belongs to the Great Basin region of Nevada 

and the desert province of Arizona. The map shows that the irregular and scattered distribution of the mining districts in this area is 

similar to that of the region mentioned. In many localities the 

geologic structure is as yet unknown. In general, the deposits may 

be grouped into those of pre-Cambrian age, those connected with 

granitic intrusions of late Mesozoic age, and lastly, those of late Tertiary age, which usually occur in surface lava flows. The few pre> 

Cambrian deposits are probably limited to the vicinity of the Arizona
20 MINING DISTRICTS OF WESTERN UNITED STATES.

boundary line and contain mainly copper ores and gold ores. The 

gold mines at Hedges, near Yuma, Ariz., probably belong in this class, 

as do those of Whipple Mountain, in San Bernardino County. The 

Mesozoic deposits are widely distributed from Mono County southward and appear as aureoles around smaller intrusions of granodiorite. They are in large part gold-bearing quartz veins, exemplified by the deposits at Randsburg, in Kern County. A number of 

small districts in the desert range of San Bernardino and Riverside 

counties contain gold and quartz veins in granitic country rock.

A smaller, number of deposits are replacements of limestone by 

galena, as at Tecopa, Cerro Gordo, and Panamint, in Inyo County. 

Still fewer are the contact-metamorphic deposits, of which examples 

may be found in the copper-bearing garnet zones of Ubehebe, in 

Inyo County, and the Standard mine at Cima, in San Bernardino 

County. In the western part of California contact-metamorphic 

deposits are very rare, though a few unimportant examples are 

found in the Sierra Nevada and the Peninsular Range. In the 

northern part of the State, in Shasta County, important contactmetamorphic deposits carrying magnetite occur between limestone 

and granitic rocks north of Pit River, and similar deposits carrying 

copper have been discovered on the same contact south of the river.

More characteristic of the eastern region are the deposits generally 

quartz veins in Tertiary rhyplite and andesite. Isolated examples 

are found along the eastern boundary of the State, as at Hayden 

Hill in Lassen County, in Alpine County, at Bodie and several other 

places in Mono County, in Inyo County, and in San Bernardino 

County. They usually carry both gold and silver, but in places (as 

at Calico) 'also silver alone. Several deposits of this kind are found 

near Mohave, in San Bernardino County.

The iron deposits of California are scattered from the southern to 

the northern part of the State. Few of them are of present economic 

importance. Most of them carry magnetite and were formed at the 

contacts or elsewhere shortly after the intrusion of deep-seated 

igneous rocks. The contact-metamorphic deposit of Herault, in 

Shasta County, has already been mentioned. Other magnetite 

deposits in granite occur at Dale, San Bernardino County, and in the 

Eagle Mountains, Riverside County, both connected with granitic 

intrusions. Another iron deposit is found at the Minarets, in the 

western part of Madera County.

Manganese deposits of minor importance as well as prospects of 

chromite are found at several places in the Coast Range. The chromite is contained in serpentine country rock.

Deposits of rare metals are not abundant in California. Platinum 

occurs in the gold-bearing gravels of northern California and in the 

Sierra Nevada, and a small quantity is saved each year. Deposits 

of scheelite are worked near Randsburg, Kern County.
GEOLOGIC INTRODUCTION. 21 

COLORADO.

The ore deposits of Colorado are confined to the western or mountainous half of the State, but within this area they are not by any 

means uniformly distributed. Parts of the area near the western and 

northwestern borders belong to the plateau province of little-disturbed rocks. These contain only a special class of copper and raremetal deposits. The southeastern part of the mountainous area is 

also poorly mineralized. The important deposits are confined largely 

to a diagonal belt trending northeast and southwest, beginning hi 

Boulder County and ending in the San Juan Mountains.

The mines of Colorado yield principally gold, silver, lead, and zinc. 

There are few distinctly copper districts and none of great importance. With some exceptions, like those of Cripple Creek, which are 

almost exclusively gold bearing, the ores of Colorado are of complex 

nature and in many places they contain all five of the metals mentioned.

The rugged Front Range, composed mainly of pre-Cambrian rocks, 

extends from the Wyoming line to the Sangre de Cristo Range, at the 

New Mexico boundary. On the whole, it is very poor in ore deposits.

West of the Front Range lies a wide belt of uplifts of complicated 

structure, trending mainly northeastward, in which the basal preCambrian is exposed at many places but elsewhere covered by a 

folded and faulted sedimentary series consisting of Paleozoic and 

Mesozoic beds of great thickness. As exemplified at Aspen, the 

sedimentary rocks consist of relatively thin formations of Cambrian, 

Ordovician, and Devonian age and several thousand feet of Carboniferous beds, in part sandy. The upper and thicker part of the Carboniferous is of dark-red color and may be considered as part of the 

"Red Beds." Above this lie 2,000 feet of Triassic "Red Beds" and 

the section is capped by Cretaceous sandstones and shales, which are 

said to reach a thickness of 3,500 feet at Breckenridge. At Leadville 

the basal formation is the Cambrian quartzite, 200 feet thick. This 

is overlain by the Silurian white limestone, 100 feet thick, covered by 

50 feet of the "Parting" quartzite of Devonian age. Above this 

comes about 4,000 feet of Carboniferous rocks, divided into the Leadville or "Blue" limestone, 400 feet thick, the "Weber shales and 

grit," 2,500. feet thick, and 1,000 to 1,500 feet of the limestone and 

red beds of the "Upper Coal Measures."

With these sediments are interbedded sheets and dikes of monzonite 

porphyries of many lands, and these intrusive rocks as a rule indicate 

the presence of mineral deposits.

The southwestern part of the State, known as the San Juan region, 

is marked by a large area of Tertiary (in part early Tertiary) volcanic 

flows of rhyolite and andesite. Intruded in this series are smaller 

masses of monzonite porphyries, and surrounding it in slightly upturned position is a thick mass of sediments, including a thin body of
22 MINING DISTRICTS OF WESTEBN UNITED STATES.

Devonian rocks, about 4,000 feet of sandstone and limestone of Carboniferous age, including the lower part of the "Red Beds," about 

1,000 feet of Jurassic and Triassic "Red Beds," and 1,500 feet or more 

of Cretaceous formations.

The northeast corner of the State is covered by flat-lying Eocene 

beds except where the east end of the Uinta uplift has brought older 

rocks to view.

As hi other States, the deposits may be conveniently divided into 

those of pre-Cambrian and those of post-Cambrian age. The latter 

are by far the more important.

The pre-Cambrian ores occur, of course, only in the rocks of the 

same age, but such occurrence alone is not a sufficient criterion for 

determining the age of the deposits. Near the northern boundary 

line and extending into Wyoming are a number of low-grade copper 

deposits for instance, those of Pearl, in Larimer County which, on 

good grounds, are held to be of this early age. Little production has 

thus far been obtained from these deposits. They are in part veins, 

in part irregular masses of pyrite and chalcopyrite, usually connected 

with intrusions of diorite or gabbro. Considerably farther south, in 

Jefferson, Fremont, and Chaffee counties, are several copper deposits, 

also in close connection with basic igneous rocks to which a similar 

age has been attributed. The most prominent among these deposits 

is that of the Sedalia mine, which also yields zinc ore. A considerable 

number of small deposits of copper ore in the Front Range and the 

Sangre de Cristo Range probably belong in the same class.

As elsewhere in the Western States, there was a long interval 

between the pre-Cambrian and the later epochs of metallization, 

which may be assumed to begin with the close of the Cretaceous or the 

beginning of the Tertiary. The division between the earlier Tertiary 

mineralization which followed the intrusion of monzonite porphyries 

and the later development of deposits in surface lava is less strongly 

marked in Colorado than elsewhere.

The principal mineral belt, extending from Boulder to Leadville 

and Gunnison, appears to be of earliest Tertiary age and its ores occur 

in a great variety of rocks from pre-Cambrian to Cretaceous, constantly associated with intrusive dikes, sheets, and masses. Most of 

the deposits bear clearly the stamp of having been formed at considerable depths below the surface. None of the deposits occur in surface flows.

Beginning from the northeast, we have, first, the gold and silver 

bearing quartz veins in the pre-Cambrian rocks of Boulder, Gilpin, 

and Clear Creek counties. Associated with them and of about the 

same age are the tungsten veins of Boulder County, which yield the 

larger part of the tungsten ores produced hi this country. There is 

little free gold, the precious metals occurring mainly in pyritic ores,
GEOLOGIC INTRODUCTION. 23

galena, or zinc blende., The veins are accompanied by a system of 

porphyry dikes. Beyond the Divide are the veins of Breckenridge, 

in Cretaceous rocks, accompanied by sheets of monzonite porphyry. 

A number of smaller districts connec^ with the great deposits of 

Leadville, in which complex pyritic ores replace limestone and carry 

silver, gold, lead, zinc, and copper. The intrusives have here taken 

"the form of thick sheets forced into the Paleozoic sediments. The 

Red Cliff and Tenmile districts are also characterized by replacement 

ores, as is Aspen, west of Leadville. At Aspen the silver-lead-zinc 

ores follow a network of fault fissures in limestone and are not so 

intimately connected with intrusive rocks; it is probable that the 

mineralization here is of more recent date than elsewhere.

To the southwest of Leadville, in Gunnison and Chaffee counties, 

lie a considerable number of less important districts exhibiting considerable variety in structure and mineralogy. A short barren stretch 

separates the Gunnison region from the San Juan region and is occupied mainly by surface lavas and tuffs originating in the volcanic 

center of the San Juan Mountains.

The San Juan region is rich in ore deposits, which carry mainly 

gold and silver, but also to some extent lead, copper, and zinc. The 

ore deposits are typically fissure veins which have a northeast or 

northwest trend. At Telluride and Ouray these quartz veins carry 

gold and some silver. At Silverton and in the Rico Mountains base 

metals are also present in abundance. The veins cut most of the 

volcanic flows of the region as well as the still later intrusive monzonites and hi places the sedimentary and pre-Cambrian rocks. Toward 

the eastern border of the region is the Lake City district and, still 

farther east, the Creede district, the quartz veins of which cut rhyolite and carry gold, silver, lead, and zinc.

The veins of San Juan County bear the marks of having been 

formed relatively near to the surface, but, as is natural from the great 

depth to which erosion has exposed the lower rocks, some of them 

present features characteristic of deposition under conditions of 

higher temperature and pressure.

Practically no contact-metamorphic deposits of economic importance exist in Colorado. The ores of Leadville recall this type in 

some ways, but lack the characteristic contact minerals.

Outside of the main mineral belt are the districts of Cripple Creek 

and Silver Cliff, both situated in the Front Range south of Denver. 

The ores of these districts were deposited relatively near the surface 

of old volcanic centers. At Cripple Creek, well known as one of the 

principal gold-producing districts of the United States, gold tellurides 

occur in veins in a dissected volcano, which, in late Tertiary times, 

emitted phonolitic lavas. At Silver Cliff the silver ores occur in 

andesite and rhyolite, in part cementing breccia-filled pipes in the
24 MINING DISTRICTS OF WESTEBN UNITED STATES.

volcanic rock. The age of this mineralization is thought to be 

Eocene.

In many of the gold districts mentioned detrital or placer deposits 

are found in the valleys bel^w the outcrops of the ore bodies. The 

richest parts of these placers were washed out many years ago, but 

they still yield some gold by modern processes of dredging and 

hydraulic work.

There are few placer deposits in the San Juan region and at Cripple 

Creek. Most of them are in the main northeast-sou thwest< belt from 

Boulder to Leadville and the most important now worked are situated at Breckenridge. Some gold is also mined from the Recent and 

Tertiary gravels of Routt County.

Colorado is poor in iron deposits. A few small magnetite deposits 

occur in Gunnison County, generally at the contact of sedimentary 

rocks and granite. The oxidized ores of Leadville in part are rich in 

iron and manganese and are utilized as flux and in the manufacture 

of spiegeleisen, an alloy of iron and manganese.

It remains to mention an entirely different class of deposits, carrying copper, vanadium, and uranium. The ores occur disseminated in 

sedimentary beds, mainly in the "Red Beds" of southwestern and 

central Colorado, and were probably formed by concentration by 

means of meteoric waters from small quantities of the metals disseminated through the beds. Vanadium and uranium bearing sandstones of Jurassic age are mined in San Miguel and Montrose counties 

and also occur in Routt County. In places copper occurs together 

with the metals mentioned, and chalcocite ores have been found disseminated in the conglomerates, sandstones, and carbonaceous 

shales of Red Gulch, in Fremont County. They are also reported 

from Huerfano County, in the south-central part of the State. The 

tungsten-bearing veins of Nederland, in Boulder County, have already 

been mentioned.

IDAHO.

Ore deposits are irregularly distributed in Idaho. The extreme 

southern and eastern parts of the State are almost barren. The 

mining districts are most abundantly clustered in a region extending from the vicinity of Boise in a northeasterly direction to Lemlii 

County and the Salmon River valley. The most important output 

is that of lead and silver from the Cceur d'Alene district, in the northern part of the State. Gold and silver are derived from the belt 

mentioned and from veins in Owyhee County, in the southwest corner 

of the State.

The most prominent geologic feature is the great central mountain 

mass bordering Montana and continued on the north by the Clearwater and Coeur d'Alene Mountains. The eastern part of this
GEOLOGIC INTRODUCTION. 25

mountain mass consists of pre-Cambrian and Paleozoic strata, the 

extreme western part of Triassic sediments. Between these two 

areas lies a great intrusive mass of granitic rocks, principally quartz 

monzonite, continued on the north and east by smaller intrusive 

areas. The northern or panhandle part of the State is mainly built 

up of the steeply inclined sedimentary strata of a thick pre-Cambrian 

complex known as the Belt series. The southern and southwestern 

parts of the State are covered by thick volcanic flows of Tertiary age 

and this area connects on the east with the lavas of the Yellowstpne 

Park region and Utah. Toward the Nevada line rise a number of 

short ranges of the type of the Basin Ranges of that State, and the 

extreme southeastern part of Idaho is occupied by north-south ranges 

built up of folded and faulted Paleozoic and Mesozoic rocks which 

may be considered as a northward extension of the Wasatch Mountain system.

Pre-Cambrian deposits are not present in Idaho, except possibly 

in some of the less important districts in the northern part of the 

State, where mineralization seems to have accompanied the intrusion 

of diabase sills in the Belt series. Here as elsewhere two important kinds of deposits may be recognized those which were formed 

shortly after the intrusion of the great central batholith of Jurassic 

rocks, probably in late Cretaceous time, and those of late Tertiary 

age which developed after the outburst of the Tertiary lavas in the 

southern and central parts of the State. The latter are confined to 

the gold and silver veins of Owyhee County and to a belt of lavas in the 

central part of the State, including such deposits as the Custer, in 

Custer County; the Singiser veins, in Lemhi County; and the Thunder 

Mountain deposits, in Idaho County.

A few unimportant deposits of copper and lead ores of uncertain 

age occur in the Paleozoic limestones of the ranges in the extreme 

southeast corner of the State.

The upper parts of the late Cretaceous ore deposits have to a considerable extent been removed by erosion and the parts now exposed contain ores formed at considerable depths. They are mainly 

fissure veins, but in places, as in southern Lemhi County and at the 

Wood River (Hailey) district, these merge into replacement deposits 

of galena in limestone. Contact-metamorphic deposits containing 

 copper ores are developed on a rather extensive scale at Seven Devils, 

near the Oregon boundary line, and at White Knob, in the southeastern part of Custer County, but neither place has proved a large 

or steady producer.

The veins are contained in a great number of districts situated in 

and around the borders of the central granitic mass. Most of them 

carry gold and silver in a quartz gangue with abundant sulphides. 

Among the best-known districts are those of the Idaho Basin and
26 MIKING DISTRICTS OF WESTERN UNITED STATES.

the vicinity of Boise, adjoined on the east by the Sawtooth, Atlanta, 

and Rocky Bar districts. To the northeast are a number of minor 

districts in Lemhi County. To the north are those of Warren, 

Florence, Buffalo Hump," Dixie, Elk City, and Pierce. Still farther 

north, surrounding a smaller granitic intrusive mass, cluster the 

lead-silver veins of the Coeur d'Alene district. The late Cretaceous 

gold-bearing veins have usually yielded placer deposits of importance, 

many of which are still producing. The placer districts of greatest 

present importance are in the Idaho Basin, along the eastern boundary 

of Lemhi County, and at Pierce. The now largely exhausted placers 

of Warren, Florence, Elk City, and the Coeur d'Alene region should 

also be mentioned. The fine gold occurring in the sands of Snake 

River has been described frequently, but the actual production from 

these deposits is very small. Placers of diminishing importance are 

situated along Salmon and Boise rivers.

Among the Tertiary veins those near Silver City and De Lamar, 

in Owyhee County, have been and are still important producers. 

These veins cut through early Tertiary rhyolites and basalt and 

bear clear evidence of having been formed within short distances of 

the present surface.

Less well known are the veins at Custer and also those of a few 

districts like Singiser, in Lemhi County, which occur under similar 

conditions. Low-grade gold ores have been mined at Thunder Mountain, in Idaho County, and are said to form disseminations in rhyolitic tuffs. The Tertiary veins carry gold and silver with a very 

small amount of sulphides and no important amounts of the base 

metals.

Idaho contains few deposits of iron ore and none of them are mined 

at present. Iron Mountain, in Washington County, near Snake River,

is the principal locality. No rare-metal deposits of importance occur

in Idaho.

MONTANA.

The ore deposits of Montana occur in the western or mountainous 

half of the State. Though a few are contained in the detached front 

ranges, the major part are situated in a cluster in the southwestern 

part of the State, practically within the area included by Helena, 

Dillon, Missoula, and Virginia City. A few are situated north of the 

Yellowstone Park, and some others near the north end of the boundary line between Idaho and Montana, but the northern part of the 

Rocky Mountain area, though traversed by several high ranges, such 

as the Main Range and the Mission Range, is singularly barren of 

mineral deposits.

The great copper production of the Butte mines (Summit Valley 

district) overshadows all the rest of Montana's metallic output, but
GEOLOGIC INTRODUCTION. 27

the State also produces annually several million dollars in gold and 

much silver and lead.

The geologic structure is complicated. The eastern part of the 

Rocky Mountain region shows a succession of dome-shaped uplifts 

hi which the Mesozoic and Paleozoic rocks are successively exposed; 

the central core consists of igneous rocks or the pre-Cambrian complex. Of such character are the Bighorn, Little and Big Belt, Moccasin, Judith, Little Rocky, and Bearpaw mountains. The main mass 

of mountains west of Helena and Livingston consists of similar systems of faulted and interlocking uplifts which expose a great thickness of sedimentary rocks. As measured near Philipsburg, the sedimentary rocks consist of a great thickness of the Algonkian (preCambrian) Belt series, amounting to about 13,000 feet of slates, 

limestones, and quartzite, then 1,200 feet of Cambrian, 300 feet of 

Silurian, 1,000 feet of Devonian, 1,200 feet of Mississippian, 700 feet 

of Pennsylvanian, 400 feet of Jurassic, and about 2,000 feet of Cretaceous rocks. In this western province, which seems to have suffered 

more erosion than the area farther east, a number of batholiths, or 

great masses of granite rocks, have been intruded. They are mainly 

quartz monzonites of late Cretaceous or earliest Tertiary age, and the 

largest of them extends from Helena for about 70 miles in a southsouthwest direction to Butte and Dillon. Several smaller intrusive 

masses surround this large body. Extensive eruptions of andesite 

lavas preceded the main epoch of intrusion.

The thick Belt series, which begins in the latitude of Butte, occupies a large part of the northern mountains of Montana, but it is as a 

rule poor in mineral deposits and contains few intrusive bodies.

The ore deposits of Montana mainly cluster in and around the great 

intrusive bodies in the southwestern part of the State. They were 

evidently formed shortly after the intrusive activity, at considerable 

depths below the surface, and their upper parts have been removed 

by erosion.

Few pre-Cambrian deposits have been observed in Montana, and 

the probable occurrences seem to be limited to copper ores associated 

with intrusive sills in the Belt series on the east side of Missouri River.

Important deposits of late Tertiary age in flows of lavas are also 

scarce, though some veins occur in rhyolite between Helena and 

Butte. Some veins in the early Tertiaiy andesites southeast of 

Helena are probably genetically connected with the monzonite 

intrusions mentioned above as occurring in this region. Near 

Helena, Boulder, and Radersburg there is some indication that hotspring activity and ore deposition have continued until a late geologic period, but definite information on the subject has not yet 

been published.
28 MINING DISTRICTS OF WESTERN UNITED STATES.

The deposits connected with intrusive bodies assume a great variety 

of form and content. Contact-metamorphic deposits are rare, but 

are known in the Elkhorn, Bannack, Argenta^ Bear Gulch, Highland, 

and Philipsburg districts; the Cable gold mine^ which has been a 

large producer, is located in the district last named. Contact deposits 

are also reported to exist near Garnet, in Granite County.

A number of deposits of the same general class are quartz veins, 

carrying gold, silver, or both. Of this kind are the formerly highly 

productive veins of Gloster and Marysville, near Helena; the GraniteBimetallic mine, near Philipsburg; and many others. More commonly the quartz veins are rich in sulphides, which carry silver and 

gold in intimate combination with pyrite, galena, chalcopyrite> and 

zinc blende. Examples of this class are plentiful in almost all the 

mining counties, especially between Helena and Boulder, where the 

old camps of Alta, Comet, and Lump Gulch are located, and near 

Dillon, in Beaverhead County.

The vein systems of the Summit Valley district at Butte carry 

mainly copper, with small amounts of gold and silver, but there are 

also veins rich in silver and zinc.

Replacement deposits of silver-bearing galena occur in the Elkhorn 

district, southeast of Helena; at Barker, in the Little Belt Mountains ; at Castle, in Meagher County, and at some other places, but 

the production obtained from these sources is not large at the present 

time.

The outlying uplifts in front of the main range contain some goldbearing deposits of importance associated with intrusions of granitic 

or monzonitic porphyries. Most prominent are those of the Moccasin 

and Warm Springs districts in Fergus .County, which are replacement 

deposits of gold-bearing quartz and fluorite in limestone, and in the 

Little Rocky Mountains, where the altered porphyry itself contains 

disseminated free gold in irregular bodies.

In Park County, north of the Yellowstone Park, are a number of 

little-known mining districts that contain gold-bearing quartz veins 

in places associated with sulphides and at one locality (in the Sheepeater district) with tungsten ores.

Near the north end of the Idaho boundary line, in the slates of the 

Belt series, are a number of vein deposits which show a close relationship to the Coeur d'Alene types, and contain galena and in places 

chalcopyrite. Genetically they are probably connected with intrusions of quartz monzonites. Among these districts the Libby, Iron 

Mountain, and St. Regis are the best known.

Wherever the deposits carry visible gold, placers have been formed 

in the gravels at lower elevations. Though the placer production is 

not large now and is derived mainly from dredging operations in the 

Alder Gulch (Virginia City) district, Montana was formerly noted for 

its rich gold-bearing gravels, which were worked not only at the place

mentioned but also near Helena, Diamond City, Bannock, and at 

many other places.

No important deposits of iron are known in Montana. Manganese 

has been mined at one or two places in Jefferson County. There are 

few notable deposits of rare metals, though tungsten ores are found 

at Butte and in the Sheepeater district.

NEVADA.

Nevada is one of the most important metal-mining States of the 

West and has produced large quantities of gold, silver, and lead. At 

present her production of precious metals is again rising rapidly, and 

although the output of lead is much smaller than formerly the State 

is now an important producer of copper. The mining districts number about 200, and a glance at. the map (PL IX, p. 200) will show that 

they are irregularly scattered over the State. The Great Basin, of 

which Nevada forms the larger part, is characterized by a great number of north-south ranges of complicated structure, separated by 

gravel-filled valleys. There is scarcely one of these ranges that is 

not mineralized to some extent. The great variety and the scattered 

distribution of the districts renders it difficult to give an adequate 

description of the metallic resources of the State within the space 

here allotted.

The northern boundary line of Nevada lies within the province of 

the Columbia River lava, and these flows of basalt and rhyolite 

extend for some distance into the State. At the bend of the California State line the Sierra Nevada forms the boundary of Nevada and 

a small part of that great range is included within its limits. A small 

area at the extreme south end of the State is occupied by the horizontal strata of the plateau province. Elsewhere the Basin Ranges 

are the dominating features, except where they are partly obliterated 

by Tertiary lava flows.

The ranges .are built up of a great variety of rocks. The pre-Cambrian basement is visible at few places except in the extreme southern 

part of the State, close to Colorado River, where granitic rocks of 

that age appear. East of a line drawn a little east of Winnemucca 

through Austin to a point somewhat west of Tonopah, Paleozoic 

strata are the predominating rocks and there is little or no Mesozoic 

material present. The typical section at Eureka shows 7,600 feet of 

Cambrian shale, quartzite, and limestone, 5,000 feet of Ordovician 

limestone with some quartzite, 6,000 feet of Devonian limestone, and 

11,300 feet of Carboniferous shale, quartzite, limestone, and conglomerate. This enormous thickness indicates the vicinity of a shore 

line, and we find, in fact, that west of the line mentioned above the 

Paleozoic disappears and is supplanted by a thick series of Triassic 

and Jurassic sediments. During the Paleozoic era western Nevada 

was a land area discharging sediments to the east. The Mesozoic
30 MINING DISTRICTS OF WESTEBN UNITED STATES.

sediments that accumulated in western Nevada were derived from a 

land area of uplifted Paleozoic strata in the eastern part of the State. 

The Triassic is typically exposed in the Humboldt Range and its limestone, slate, sandstones, and associated flow rocks attain a thickness 

of 10,000 feet. The Jurassic is present in the range about Winnemucca, and also in the Humboldt Range. Its total thickness is considerable but not exactly known on account of extensive folding and 

metamorphism; it consists mainly of slates with some limestones.

Intrusive igneous rocks of the type of granodiorite, quartz monzonite, or corresponding porphyries are abundant but form smaller 

areas. These irregular masses or batholiths are most common in the 

western part of the State adjacent to California, but they also occur 

in the Paleozoic ranges of eastern Nevada. Their age appears to 

range from latest Jurassic to earliest Tertiary; those near the Sierra 

Nevada are probably the older. Tertiary flow rocks andesite, rhyolite, and basalt are widely distributed and cover large areas, some 

ranges being entirely built up of them. The lavas near the northern 

boundary have already been referred to. Another large field lies 

adjacent to the southwest corner of Utah, and from thai vicinity 

toward the California boundary the lava flows are especially prominent. Some of the western flows are probably of Eocene age, but it 

is clear that the eruptions continued throughout the Tertiary period.

The old lavas contain in some places small intrusions of monzonite. i r

The sedimentary rocks of the ranges have been folded and faulted. 

At some places the faulting is comparatively old, but at other places 

it is later than some of the lavas and is still visible in the topographic 

forms; in this case the ranges are apt to be monoclinal in structure.

The ore deposits fall into three classes according to their age and 

occurrence pre-Cambrian, Cretaceous or early Tertiary, and middle 

or late Tertiary.

The pre-Cambrian deposits are very poorly represented. There 

is, in fact, only one occurrence which may with some confidence be 

placed in this class. It is in the Copper King district, near Bunkerville, Clark County, where basic dikes carry copper, nickel, and platinum.

The Cretaceous or early Tertiary deposits are invariably connected 

with intrusions of granodiorite or quartz monzonite, and as they 

have suffered much erosion since their formation the now accessible 

parts were formerly deeply buried. Gold, silver, copper, lead, and 

zinc are the principal metals.

There are several types in this class. Contact-metamorphic deposits between or near the boundary of limestone and intrusive rocks are 

not abundant nor have they yielded a great production; copper is 

the most prominent metal. They have been noted at Yerington 

(Mason district), in Lyon County; at Coppereid, in Churchill County; 

at Adelaide and the Jackson Mountains, in Humboldt County; at
GEOLOGIC INTRODUCTION". 31

Cortez, in Lander County; at Bullion, Lone Mountain, Lime Mountain, and Contact, in Elko County; and at Ely and Ward, in White 

Pine County.

Eeplacement deposits of argentiferous galena in limestone or 

quartzite, usually situated at some distance from the contacts but 

apparently connected genetically with intrusive masses, have yielded 

a large but now diminishing output. At many places transitions into 

normal fissure veins are observed. To this class belong the celebrated deposits at or near Pioche, in southern Nevada and those at 

Eureka, in Eureka County, although in the latter place there is some 

doubt about the genetic connection, for both rhyolite and acidic 

intrusive rocks occur in the district. Other districts are the Lida, 

Montezuma, and Southern Klondike districts, in Esmeralda County; 

the Rye Patch mine in the Humboldt Range, Humboldt County; 

Cortez and Mill Canyon in Lander County; Mineral Hill, in Eureka

County; and many others.

There are all transitions between these replacement deposits and 

silver and lead bearing veins in quartz gangue, often accompanied by 

rich silver minerals; these may cut through the sedimentary or the 

intrusive rocks and they occur in so many places that it would be 

difficult to enumerate all. At Austin, in the Reese River district, 

silver-bearing veins cut granite; at Belmont, Nye County, they are 

contained in Paleozoic sediments in which granite is intruded; at the 

Horn Silver district, 26 miles south-southwest of Goldfield, the veins 

are contained in early Paleozoic beds. In the oxidized parts of these 

veins horn silver and rich sulphantimonites and arsenites usually 

occur in abundance, changing to poorer sulphides below water level.

In still another,group of veins gold predominates, locally as native 

gold accompanied by quartz gangue but more commonly in association with more or less sulphides and some silver. These veins are 

usually found in or near intrusive bodies. Examples of their occurrence are in the Silver Peak district, Esmeralda County; at Edgemont, in Elko County; at Osceola, in White Pine County; and in the 

Humboldt and Santa Rosa ranges, in Humboldt County. Many of 

the gold-bearing quartz veins occur in quartzite. At De Lamar, 

Lincoln County, for instance, a bed of quartzite penetrated by basic 

dikes has been impregnated with gold-bearing solutions and during 

its oxidation the gold was concentrated into a valuable mass of ore 

which for many years yielded a large production.

Pyritic disseminations, usually in porphyry, accompany this type 

of mineralization in many places, and where, as at Ely, White Pine 

County, these disseminations have been worked over by descending 

waters, important low-grade blanket deposits of chalcocite may be 

developed.

The various types mentioned may all occur in the same district, 

together forming a metallic aureole in and around intrusive masses.
32 MINING DISTRICTS OF WESTERN UNITED STATES.

The Tertiary mineralization of lavas in Nevada occurred on a 

scale and with a diversity not equaled elsewhere in the Western 

States. It took place at several epochs, and in places each eruption 

was followed by the ascension of metal-bearing solutions, which 

penetrated and altered great areas of the porous volcanic rocks, 

causing what is termed propylitization. The main epoch of mineralization appears to have been, in the Miocene. The deposits are in 

veins or shear zones; some of them in extensive and irregular masses 

of silicified lavas. They occur in andesite, latite, dacite, or rhyolite, 

but few of them in basalt. The metals are gold and silver, which in 

many places occur together, in a quartz and adularia gangue, more 

rarely, as at Bullfrog, accompanied by calcite. Native gold is not 

common below the water level, though it is present, for instance, in 

the Round Mountain and National districts; above the water level 

the oxidized material usually carries gold. Copper, lead, and zinc are 

subordinate.

Districts of this type are abundant in western Nevada but are in 

fact scattered all over the State. Veins in andesite constitute the 

great Comstock deposits, in Washoe County; those of Tonopah, 

Kawich, and Gold Crater, in Nye County; Tuscarora, Cornucopia, 

and Stafford, in Elko County; and Seven Troughs, in Humboldt 

County. Veins in rhyolite are abundant and usually carry gold 

and silver. As examples of such districts may be mentioned Fairview and Wonder, in Churchill County; Bullfrog, Silverbow, Eden, 

Cactus Springs, Wilson's Camp, Stonewall Mountain, and Wellington, 

in Nye County; Rawhide, Esmeralda County; Gold Circle, Elko 

County; and National, Humboldt County. The Goldfield mines, 

which in late years have yielded a large production of gold, are 

working irregular bodies of altered and silicified rocks in latite.

By far the greater part of the gold and silver production of Nevada 

is derived from these Tertiary veins.

Placers have yielded large amounts of gold in Nevada, but in the 

absence of an abundant supply of water they are difficult to work 

Both Cretaceous and Tertiary deposits have contributed to the 

formation, though they are practically absent from many of th 

richest Tertiary deposits, such as the Comstock lode and the deposit, 

of Tonopah and Goldfield.

The gold-bearing gravels have been worked at Tuscarora, in the 

Humboldt Range, at Round Mountain, at Battle Mountain, and at 

numerous other places.

Iron ores are not of frequent occurrence. Brown iron ores are 

reported from Montello, Cobre, and Moor, Elko County, and from 

Winnemucca, Humboldt County. Magnetite deposits are said to 

occur some distance east of Lovelocks, Humboldt County; in the 

Cortez Mountains, Eureka County; and near Bullion and Dolly 

Varden, Elko County; Little is known about their geologic relations.
GEOLOGIC INTRODUCTION. 33

Nickel and cobalt'ores occur in diorite and andesite of probably 

Mesozoic age, in the Cottonwood Canyon district, in the Humboldt 

Range.

Tungsten ores as wolframite or htibnerite are worked near Osceola, 

White Pine Couiity, and near Browns station, in southwestern 

Humboldt County. In minor quantities the ore occurs in many 

Tertiary veins, for instance, at Tonopah and Round Mountain.

Quicksilver ore (cinnabar) is of widespread occurrence in western 

Nevada, in Humboldt, Nye, and Esmeralda counties, but its exploitation has been attempted only at lone, in Nye County. The ore 

usually occurs in Tertiary deposits in rhyolite or andesite associated 

with stibnite, locally also with gold and silver. At Steamboat 

Springs, in Washoe County, the decomposed granite contains some 

cinnabar evidently deposited by hot springs. The deposits in the 

Humboldt Range are of uncertain age and occur in Triassic or Jurassic sedimentary rocks.

NEW MEXICO.

' The ore deposits of New Mexico form a gradually widening belt 

extending through the central portion of the State from Colfax 

County, at the north, to the southwest corner; in this southern part 

the districts are scattered over a wide area between El Paso and 

Silver City. In spite of the fact that there are numerous districts, 

the production of New Mexico is not large. Gold, silver, copper, 

lead, and zinc are the principal metals of the output, and Grant 

and Socorro are the principal productive counties.

New Mexico contains several well-defined geologic provinces. 

Over the smaller eastern portion extend high plains or plateaus of 

horizontal or gently dipping Tertiary, Cretaceous, and Carboniferous 

sediments. About the middle of the State these almost connect 

with the similar strata of the plateau province which cover the north- 

-western part, their monotony being broken only by several minor 

uplifts like the Zuni Mountains.

^ Through the center of the State and trending north and south are 

Q£,r, succession of ranges. Toward the Colorado boundary they are 

^jigh and assume the type of the Rocky Mountain uplifts, with a 

central core of pre-Cambrian rocks surrounded by the upturned 

edges of Paleozoic and Mesozoic strata. Toward the south they are 

lower and are of the monoclinal type of the Basin Ranges, being 

limited on the east or west side by prominent faults. The preCambrian is less prominently exposed and the sediments comprise 

a thick series. In the central part of the State a thin bed of Cambrian quartzite is covered by a few hundred feet of Ordovician, 200 

feet of Devonian shale, 100 feet of Mississippian, and 3,000 feet of 

Pennsylvanian limestone and sandstone, the upper part including 

some of the "Red Beds." Above this lies a small thickness of prob21528° Bull. 507 12 3
34 MINING DISTRICTS OF WESTERN UNITED STATES.

ably Jurassic strata, and these are in turn covered by at. least 3,000 

feet of Cretaceous coal-bearing sandstones and shales. The southwest corner of New Mexico is occupied by a number of low ranges of 

the Arizona type, trending north-northwest, separated by wide 

desert plains and built up of folded and faulted Paleozoic and Mesozoic sediments; these ranges rarely have pronounced monoclinal 

structure. Lavas of late Tertiary age, chiefly andesitic and rhyolitic, 

cover a large space in the southwest, separating the province of the 

desert ranges from the plateau province. These lavas "also extend 

toward the northeast and occupy large areas north of Santa Fe, but 

are here mainly basalts of latest Tertiary or even Quaternary age. 

Minor intrusions of quartz monzonites of late Cretaceous or early 

Tertiary age are known in nearly all the ranges and follow closely in 

their distribution the trend of the main mineral-bearing districts.

Deposits of pre-Cambrian age are known to occur in the northern 

ranges in Coif ax, Taos, and Rio Arriba counties. Copper and gold 

are the principal metals. The deposits form either lenticular quartz 

veins or disseminations of sulphides in basic igneous rocks. At the 

Hamilton mine, in the Pecos district, Carboniferous strata cover the 

decomposed outcrops of a copper deposit of the latter kind. Many 

of the deposits contain minerals like garnet, tourmaline, and amphibole. The principal locality is that of the Hopewell and Bromide 

districts, in Rio Arriba County, where veins of this kind and placers 

derived from them have been mined.

In New Mexico, as elsewhere in the Western States, the most abundant deposits are those which are formed at the end of the Cretaceous 

or in the earliest Tertiary and which stand in close connection with 

granite or monzonite intrusions, surrounding them like metallic 

aureoles. There are several subdivisions of this genetic class which 

yield ores of gold, silver, copper, lead, and zinc.

Contact-metamorphic deposits in the silicate zone between limestone and intrusive rocks are more abundant than in any of the other 

States except possibly Arizona. They carry copper ores in the 

Elizabethtown, San Pedro, Organ, Jarilla, Hanover, and Hachita 

districts; lead and zinc ores are developed in the Magdalena and Tres 

Hermanas districts; iron ores at Hanover, Jones Camp, and other 

places. In all, 13 districts with such ores are known. Magdalena, 

San Pedro, and Hanover have yielded a considerable production of 

base metals.

Quartz veins almost invariably accompany the intrusions and are 

chiefly of the gold-bearing pyritic type, though in places they also 

carry silver, lead, and copper. The principal producing districts of 

this kind are Elizabethtown, Ortiz, White Oaks, and Pinos Altos. 

The silver veins form a smaller group, most of them occurring in 

Grant County Replacement deposits of argentiferous galena or sil-
GEOLOGIC INTEODUCTION. 35

ver ores are found at some little distance from the intrusive contact 

and have been mined in the Organ, Hermosa, Kingston, Hillsboro, 

Lake Valley, Georgetown, Victorio, Chloride Flat, and Granite Gap 

districts.

In connection with this general type of mineralization near intrusive bodies, there are at a few places, such as the Burro Mountains 

and Santa Rita, in Grant County, disseminations of cupriferous 

pyrite which are too poor to mine in themselves, but which have 

been enriched by a Recent or late Tertiary deposition of chalcocite 

formed by descending waters. These deposits now form large bodies 

of low-grade copper ore which are the mam source of the copper 

production of the State.

Placer deposits which formerly were highly productive are worked 

at Elizabethtown, in Coif ax County,. in the Ortiz and San Pedro 

Mountains, at Hillsboro, and at Pinos Altos. Most of them are 

derived from the veins of early Tertiary age.

A distinctly later mineralization than that described above developed in some places in the lavas of middle or late Tertiary age, shortly 

after their eruption. It produced quartz veins carrying chiefly gold 

and silver and with certain characteristics indicating deposits near 

the surface. The principal districts are at Cochiti, in ~Sandoval 

County; at Hillsboro and in the Black Range, in Sierra County; and 

in the Mogollon district, in Socorro County. At present the principal 

production of gold and silver of the State is derived from the Mogollon 

district.

Concentrations of chalcocite in the sandstones of the "Red Beds" 

of Triassic or late Carboniferous age are found at Tecolote and other 

places in San Miguel County; in the Nacimiento and Zuni mountains, 

in the northwestern part of the State; at Estey, in Lincoln County; 

at Tularosa, in Otero County; and at several other places. The 

origin of these copper ores is still under discussion, but they have 

probably been concentrated by meteoric waters from small amounts 

of metal contained in the sandstones and this concentration has most 

likely been in progress ever since a water circulation was established 

in the strata involved. The deposits are in general independent of 

igneous rocks.

The iron ores consist chiefly of magnetite, occurring in contactmetamorphic deposits. They have been mined at Fierro, in Grant 

County. A bed of limonite in Cretaceous strata has also been mined 

near Glorieta, in Santa Fe County.

Bismuth ores occur in. the San Andreas Range. Vanadium ores 

occur near Hillsboro and in the Caballo Range, in both places in 

connection with galena deposits in limestone. Some wolframite has 

been recovered from a quartz vein in limestone in the Victorio district, Luna County.

OREGON.

The map (PL XI, p. 246) shows plainly that the metal deposits of 

Oregon are confined to two small and widely separated regions. The 

northeastern part of the State, including Baker and Grant counties, 

contains a number of districts yielding mainly gold and silver but 

also some copper. The southwest corner, including parts of Douglas, 

Josephine, Jackson, and Coos counties, holds the extreme north end 

of the California gold belt, and the mines here yield gold, though 

there are also a few copper-bearing districts.

With the exception of these relatively small areas, the whole State 

is covered or underlain by flows of late Tertiary lavas, mainly andesites 

and basalts, or, as along the western coast, by Tertiary or Cretaceous 

sediments. Here and there the older rocks are exposed under the lavas, 

as in the Puebla Mountains,, near the Nevada boundary line, and here 

some older mineralization may appear. In a few places, as in the 

Bohemia district, in the southern Cascade Mountains, and at a few 

points to the north in the same range, mineralization appears in 

the andesite rocks, resulting in deposits of gold and silver or quicksilver, but this, too, is unusual.

In geologic structure both regions belong to the Pacific type in 

which considerable regional metamorphism has been superimposed 

upon Paleozoic and Mesozoic rocks.

In southwestern Oregon the rocks are essentially the same as in 

the Sierra Nevada and in northern California. The structural trend 

here swings around from a northwesterly to a northeasterly direction. 

The sedimentary rocks comprise Devonian, Carboniferous, and 

Jurassic strata, the thickness of which is difficult to measure on 

account of the intense compression to which they have been subjected. These beds are intruded by granodiorite and its porphyries, 

as well as by serpentine and greenstone; the intrusions are earlier 

than the Cretaceous rocks, which also have a considerable development in the region. The gold-bearing quartz veins and the placers 

derived from their eroded outcrops stand in close connection with the 

intrusive porphyries and greenstones. Most of them are situated 

near Ashland and Jacksonville and especially north of Grants Pass. 

There are a great number of loosely defined districts, among which 

may be mentioned the Greenback, Gold Hill, Applegate, Jalico, 

Grave Creek, and Waldo. In all these districts placers accompany 

the veins. A few scattered gold deposits are situated in Coos and 

Curry counties. Gold-bearing black sands are mined at Gold Beach, 

Port Orford, and other places, the fine gold having probably been 

transported to the sea by the river which drains the auriferous 

region.

Of the rarer metallic products, nickel ores have been mined at 

Riddles, in Douglas County. Platinum occurs rather commonly but
GEOLOGIC INTRODUCTION. 37

only in small quantities in the gold-bearing gravels and beach sands 

and is probably derived from the serpentine rocks. Small quantities 

of this metal are recovered. Quicksilver occurs as low-grade cinnabar 

ore at Black Butte, in Douglas County.

In the Blue Mountains of northeastern Oregon, which stand out 

above the surrounding lava flows, there is a highly compressed and 

not easily measured section of Paleozoic rocks and an overlying 

less highly altered series of Triassic sediments, the latter extending 

northeastward across Snake River and into Idaho, by the Seven 

Devils copper district. These sedimentary rocks are intruded by a 

number of smaller masses of granodiorite, in and around which the 

gold-bearing quartz veins cluster. The veins as a rule carry more or 

less sulphides and contain more silver than the gold veins of the 

southwestern part of the State. The richest veins are those of the 

Cracker Creek district, near Sumpter; others in the same vicinity in 

Baker County are the Bonanza, Cable Cove, Elkhorn, Connor Creek, 

Virtue, and Cornucopia. The adjoining Grant County contains 

similar veins at Susanville, Quartzburg, Granite, and Canyon City. 

Placers accompany the veins, especially at Sumpter, Baker City, and 

Canyon City. The last-named place marks the west end of this goldbearing region, whose southeastern limit is at Humboldt Basin, in 

Malheur County.

SOUTH DAKOTA.

Cretaceous and Tertiary horizontal sediments cover almost the 

whole of the State of South Dakota, but in the southwest corner 

rises a prominent outlier of the Rocky Mountains, known as the 

Black Hills, which contains gold deposits of great economic importance. This group is similar to the uplifts of Wyoming and Montana, 

its center being an elliptical mass of pre-Cambrian schists and granites surrounded by outward-dipping Cambrian, Carboniferous, Jurassic, and Cretaceous beds. In the northern part of this uplift are 

masses, sheets, laccoliths, and dikes of porphyries of phonolitic, rhyolitic, and andesitic types, the age of which0 is considered to be 

Eocene.

Both pre-Cambrian and Tertiary (probably Eocene) ore deposits 

are found in the Black Hills. The pre-Cambrian deposits include 

lenticular veins in the schists, with quartz, native gold, and sulphides. Of these the most prominent example is the great Homestake mine at Lead, which is a low-grade but very large deposit of 

lenses in mica schist. These lenses of altered rock contain quartz 

stringers and much amphibole and carry native gold and auriferous 

sulphides. Somewhat similar but as yet not productive deposits 

occur in other parts of the pre-Cambrian area, in Lawrence, Penm'ngton, and Custer counties. There are also low-grade copper depos-

its consisting of pyritic disseminations in schists, but at present none 

of these are productive.

The placer deposits, which now yield but little, were derived 

from veins in the schists. The oldest placers .were accumulated in 

the conglomerate at the base of the Cambrian, when the Paleozoic 

sea first transgressed over the disintegrated pre-Cambrian rocks. 

Quaternary gold-bearing gravels lie in the present stream beds.

In the southern part of the Black Hills the granitic pre-Cambrian 

rocks hold pegmatite dikes which contain cassiterite, wolframite, and 

various tantalum-columbium minerals, also amblygonite and other 

lithia-bearing minerals.

A type of gold ore entirely different from that of the pre-Cambrian 

is connected with the intrusive porphyries, and the mineralization 

which produced it is probably of early Tertiary age. These gold 

ores, which do not carry visible metal, are siliceous replacements of 

Cambrian dolomite limestone, locally also of quartzite and shale; 

they occur in'flat shoots following the stratification and are connected 

with usually barren vertical fissures that are believed to have formed 

the ducts for the passage of the solutions which caused the deposits. 

Cyanidation is the usual process of treatment and the ores, though 

now of -medium to low tenor in gold, contribute largely to the production of the region. The ores are confined mainly to the northern 

part of the Black HiLls, in Lawrence County. Wolframite occurs in 

one or two places in connection with these refractory siliceous oresTEXAS (WESTERN PART). .

The western or trans-Pecos part of Texas contains a number of 

small mining districts in El Paso, Presidio, and Brewster counties. 

The principal metal production is limited to silver and quicksilver.

From eastern New Mexico a chain of short ranges indicated by 

the White Mountains, the Sacramento Range, and the Guadalupe 

Mountains extends southward into western Mexico; they are built 

up of Carboniferous and Cretaceous strata with small bodies of 

igneous rocks. A little farther south, in Presidio and Brewster counties, is a large area of volcanic flows which extends southward into 

Mexico.

The scattered mining districts in El Paso County have not yet 

proved of importance. In Presidio County is the Shafter district, 

which for several years has produced a notable amount of silver 

from an irregular oxidized deposit in Carboniferous limestone. .East 

of the volcanic area mentioned the Cretaceous strata contain many 

small areas of volcanic flow rocks, in or near which, at Mariscal and ' *

Terlingua, important quicksilver deposits are located. Tin ore is 

mined near El Paso in the Franklin Mountains, where it occurs in a 

granitic rock.
GEOLOGIC INTRODUCTION. 39 

UTAH.

The ore deposits of Utah are in the main confined to the western 

part of the State. They begin near the southwest corner of the 

State; thence the line between..the productive and the barren region 

trends north-northwest, and in the latitude of Utah Lake and Salt 

Lake follows the crest of the Wasatch Range. The extreme northern 

part of the State, adjoining Idaho, contains few deposits. In the 

eastern region lie a few deposits of copper and rare metals in sandstone, on Grand River, a few iron deposits, and the gold-bearing district of the La Sal Mountains, near the Colorado boundary line.

Utah produces gold, silver, copper, and lead in large quantities and 

in the last few years the output of zinc ore has also been increasing.

The distribution of the districts corresponds to the two geologic 

provinces into which the State is divided. The unproductive area 

lies in the plateau province, in which Paleozoic, Mesozoic, and Tertiary strata are almost horizontal and igneous intrusions are generally 

absent. The ore-bearing area corresponds to the eastern part of the 

Great Basin, which is characterized by northward-trending ranges 

separated by desert plains. These ranges are built up of a thick 

series of Paleozoic sediments similar to that of eastern Nevada. 

Along the Wasatch Range Triassic, Jurassic, and Cretaceous rocks 

are also present. A typical section of the sedimentary strata comprises 10,000 or 12,000 feet of Cambrian quartzite, 1,500 feet of Silurian limestone, 1,250 feet of Devonian quartzite, 10,000 to 15,000 

feet of Carboniferous limestone and quartzite, and finally about 5,000 

feet of uppermost Carboniferous (Permian) or Triassic shales, sandstone, and limestone, the upper portion of which grades into the 

Mesozoic and consists in part of "Red Beds." In these folded and 

faulted sediments are numerous intrusions of granodiorite and quartz 

monzonite, and in places they are covered by Tertiary flow rocks like 

andesite, latite, and rhyolite. The largest area of intrusive rock is 

in Cottonwood Canyon, in the Wasatch Range, but even this is of 

comparatively small dimensions. The largest area of lavas is that of 

Beaver and adjacent counties in the southern part of the State, and 

this covers several thousand square miles. Toward the west it is 

continued across the Nevada line in the direction of Pioche.

The intrusive rocks are of post-Jurassic age; probably most of them 

date back to the late Cretaceous, but there is also reason to believe 

that granular rocks were intruded during early Tertiary time into 

some of the lofty volcanoes which at that time were situated in front 

of the Wasatch Range. The effusive rocks the lavas began to 

pour out early in the Tertiary period, and the maximum stage of their 

eruption falls in the later part of that period, though the basaltic 

eruptions which followed the andesite and rhyolite continued well 

into Quaternary time.
40 MINING DISTRICTS OF WESTERN UNITED STATES*

No pre-Cambrian ore deposits are known in Utah. -As elsewhere 

the ores are, in a broad way, divided into those of Cretaceous age connected with intrusive rocks and those contained in lavas of late Tertiary age. Owing to the presence at some places of early Tertiary 

intrusions into volcanic cones, the line between these two classes is 

here and there difficult to define strictly.

Contact-metamorphic deposits carrying copper and some gold have 

been noted in the Frisco district, Beaver County; at Clifton, Tooele 

County; and in Cotton wood Canyon, Salt Lake County. Copper 

deposits allied to them are also found at Bingham. Emplacement 

deposits of silver-bearing galena occur in many districts and are as a 

rule intimately connected with fissure veins. Examples are furnished 

by the districts of Park City, Tintic, West Tintic, Cottonwood, American 

Fork, Frisco, Star, Fish Springs, and Willow Springs. Replacement 

deposits of copper ores in limestone are worked at Bingham and 

Tintic. Copper ores disseminated in monzonite and accompanied 

by tourmaline are mined at the Cactus mine, in the Frisco district. 

Gold-bearing replacement deposits of limestone are mined on an 

extensive scale at Mercur, in the Oquirrh Range, and appear to be 

genetically connected with intrusive sheets of porphyry.

Gold and silver bearing fissure veins in or near intrusive rocks occur 

at many places, among which may be mentioned Bingham and Tintic, 

but they do not contribute a large share to the gold production of the 

State. At Bingham there are widespread impregnations of cupriferous pyrite, and its enrichment by chalcocite deposited by descending solutions has given rise to the great low-grade copper deposits 

now worked by open-cut methods.

Placers derived from veins and other deposits connected with intrusive rocks have yielded a small production in Utah. Such gravels 

have been worked at Bingham, in the La Sal Mountains, and along 

San Juan River.

Veins 'formed during the volcanic activity in middle Tertiary time 

occur mainly in andesites and rhyolites and carry chiefly gold and 

silver; the principal localities are in the Kimberly, Mount Baldy, and 

Ohio districts, in the volcanic center situated in Piute County; similar 

veins are found in the Stateline district, bordering on Nevada, in 

Iron County.

Differing from all the preceding types are the metal-bearing sandstone ("Red Beds") of the plateau province. They show no evidence 

of genetic connection with igneous rocks. Silver and copper ores of 

this kind have been mined at Harrisburg (Silver Reef), in Washington County, and similar copper ores in sandstone are reported from 

Uinta County, in northeastern Utah. Vanadium and uranium ores 

occur on Grand River near the Colorado line.

Some quicksilver is found in the gold ores of the Mercur or Camp 

Floyd district, from which some production of this metal has been
' GEOLOGIC INTRODUCTION. 41

reported, and a selenide and a sulphoselenide of mercury occur in 

veins of the Ohio district, near Marysvale.

Iron ores are found at several points. In the Iron Springs district, 

Iron County, and at Bull Valley, Washington County, are considerable 

bodies of magnetite in deposits of contact-metamorphic origin, 

between porphyry and limestone. A hematite deposit in Carboniferous limestone occurs at Rhodes Plateau, in Summit County, in the 

Uinta Mountains. Brown iron ores in small masses are not uncommon. One of these deposits, contained in probably Mesozoic sandstone, occurs in the northeast corner of the State near Vernal

WASHINGTON.

The metal production of the State of Washington includes gold, 

silver, copper, and lead, but the output of each metal is comparatively 

small. The southern half of the State and the Olympic Peninsula 

are almost wholly covered by Tertiary basaltic flows or by Cretaceous 

and Tertiary sediments barren of metal deposits. In contrast to this, 

the northern part of the Cascade Range, as-well as the mountainous 

region extending eastward to Idaho along the international boundary, 

is built up of metamorphosed Paleozoic sediments, mainly slates with 

smaller masses of limestone, into which a number of granitic masses 

were intruded during late Cretaceous and early Tertiary time. Lavas 

of Tertiary age cover these rocks in a number of places.

Ore deposits of pre-Cambrian age have' not been reported from 

Washington but may possibly occur in the Kettle River region, near 

the Canadian boundary. In the late Tertiary lavas, in spite of the 

large space they occupy, mineralization is of rare occurrence. There 

are, however, three prominent districts in the deposits of this kind, 

all in andesitic rocks. The first is at Monte Cristo, in Snohomish 

County, in the Cascade Range, where gold-bearing veins occur with 

abundant sulphides and arsenopyrite. The second is the Republic 

district, in Ferry County, in the northeastern part of the State, where 

gold-bearing veins with chalcedonic quartz still yield a notable 

production.' The third is the Pierre Lake district, at Orient, in 

Stevens County, the output of which has been rather large for several 

years.

Practically all the other metal deposits of Washington are of 

greater geologic age and were probably formed shortly after the 

intrusion of granodiorite and similar rocks in the Paleozoic sediments 

at the close of the Cretaceous period. Extensive erosion of the 

upper parts of the veins has left exposed the deeper-seated portions. 

There are scattered districts of this kind in the Cascade Range, but 

none of them have as yet an important production. The Blewett 

or Peshastin district, on the eastern slope of the Cascades in Chelan 

County, is the best known. Rich gold ores have also been found in
42 MINING DISTRICTS OF WESTERN UNITED STATES.

the Mount Baker district, in the northern part of the Cascade Mountains, where gold-bearing quartz veins associated with dikes of 

granodiorite have cut through peridotite and Paleozoic sediments.

Most of the producing districts are situated in Okanogan, Ferry, 

and Stevens counties, and many of them lie close to the Canadian 

boundary. Contact-metamorphic deposits carrying copper are represented by those at Buckhorn Mountain, in Okanogan County, and at 

the Belcher Camp, in Ferry County, near Republic. Silver-lead 

veins occur at Conconully (Ruby Hill), in Okanogan County; auriferous quartz veins on the Methow, in the same county, and in many 

other smaller districts. Lead ores, without much silver, occurring 

as replacements in limestone, are present near Bossburg and Colville 

and in the Metaline district, all in Stevens County, in the northeast 

corner of the State. There exists here between the town of Chewelah and Clark Fork of the Columbia a large body of granite intrusive 

in Paleozoic slates and limestones, and it is held that the numerous deposits in this part of the State were formed shortly after this 

intrusion.

The State contains few placer-mining districts of importance. 

Among those which yielded much gold in the early days may be 

mentioned the Swauk and Peshastin districts.

Iron ores are present at a number of places, but are not as yet 

utilized. Magnetite is found at Snoqualmie Pass, in King County, 

in connection with metamorphosed limestone, and on Skagit River, 

in the northern Cascades, as lenses in slate. Chromiferous magnetite 

appears at Clealum, in Kittitas County, on the contact between 

sandstone and serpentine. Brown iron ore and bog iron is found at 

several places in Stevens County for instance, near Colville and 

Chewelah.

Of the rarer metals, nickel occurs in quartzose ores near Keller, 

Ferry County. Cassiterite or oxide of tin has been found in granite 

near Spokane. 3/Vblframite, an important tungsten ore, occurs at 

the same place, and also in larger quantities, together with some 

bismuth minerals, in the quartz veins of the Deer Park and Spring 

Dale (Cedar Canyon) districts, in Stevens County. Arsenic has been 

recovered from the pyritic veins of the Monte Cristo district. A 

quartz vein carrying molybdenite has been discovered in the granite 

near Lake Chelan.

WYOMING.

The State of Wyoming contains few and scattered metal-bearing 

districts, and its production is limited to a little gold and copper. 

Wide stretches of high plains or high plateaus underlain by horizontal Tertiary and Cretaceous sediments extend over the eastern and 

southwestern parts. The several uplifts of the Rocky Mountains 

traverse the State in a northwesterly direction and comprise a number of high ranges, usually exposing a large core of pre-Cambrian
GEOLOGIC TNTBODUCTION. 43

rocks surrounded by upturned Paleozoic and Mesozoic sediments. 

There is little or no evidence of the late Mesozoic intrusions which in 

other parts of the West were so effective in promoting mineralization.

In the southern part of the State are the Laramie Hills, the Medicine Bow Range, and the Sierra Madre. In the northwestern part 

rise the Wind River, Teton, and Bighorn ranges, as well as the high 

plateaus of the Yellowstone Park region, the latter covered by a 

large area of effusive Tertiary lavas. If uplift and active water circulation produce mineral deposits, they surely ought to be abundant 

in this State, and if the metals could be concentrated by such circulation the pre-Cambrian igneous rocks, which undoubtedly contain 

traces of metals, would offer a source for such concentration. The 

general absence of ores of date later than the uplifts goes far to prove 

that metallization is dependent on other conditions.

Near the eastern, boundary of the Yellowstone Park are some districts which have produced little and whose geologic features are not 

well known. Of the districts investigated practically all contain deposits of pre-Cambrian age, inclosed in the highly altered pre-Cambrian sediments or in the large masses of granitic and basic rocks 

intruded with them before the beginning of the Paleozoic era. The 

Laramie Hills contain many low-grade copper deposits in lenticular 

veins and disseminations in schists and granite. In the Medicine 

Bow Range are several districts yielding gold and copper; in the 

adjacent Sierra Madre, near the Colorado line, is the well-known 

Encampment district, which has yielded much copper and gold from 

veins and irregular deposits of pyritic ores enriched by chalcocitization in or near pre-Cambrian gabbros. Copper deposits are also found 

in similar rocks south of Casper. At several places the pre-Cambrian 

contains lenticular quartz veins with native gold; the best known deposits of this land are at Atlantic and South Pass, in Fremont County. 

Placers below rich veins have been worked at the places mentioned 

and in several districts in the Medicine Bow Range. The basal conglomerate of the Cambrian in the region adjacent to the Black Hills 

is said to contain some placer gold.

Iron ores are found in the pre-Cambrian rocks. Iron Mountain, 

north of Cheyenne, in* Laramie County, is a huge dike of ilmenite, in 

anorthositic rock, as. yet not utilized. At Hartville, in the same 

county, lenses of hematite are worked, lying between the pre-Cambrian 

and the overlying Carboniferous. They are considered to be of preCambrian age. Similar deposits are said to occur near Rawlins and 

in the Seminoe Mountains, in Carbon County.

There are few deposits of rare metals in Wyoming. Platinum, 

palladium, and other platinum rnetals are found associated'with copper minerals in the Rambler mine, near Holmes, in Albany County. 

They are reported to be present in the concentrates in paying 

quantities.
PART II. CATALOGUE OF MINING DISTRICTS.

By JAMES M. HILL.

ACKNO WLED GMENTS.

The writer is indebted to members of the United States Geological 

Survey who have supplied much first-hand information on many 

mining districts about which little has been known or published. 

The maps have been inspected by the men most familiar with the 

regions covered by them and have thus gamed much in accuracy of 

location. To Mr. H. D. McCaskey the writer is indebted for advice 

as to method and arrangement and for constant cooperation throughout the work of compilation. Mr. Waldemar Lindgren has been a 

never-failing source of information. His careful scrutiny of the 

maps, lists, and text has added greatly to their value. Sincere 

thanks are due to him for his help and for the geologic introduction 

to this bulletin.

PLAN OF THE WORK.

In 1907 the United States Geological Survey issued, as a part of its 

publication "Mineral resources of the United States/' a map showing 

by means of dots the relative location of the gold, silver, copper, lead, 

zinc, and quicksilver mining districts of the Western States. This 

map was published in one large sheet covering all the States west of 

the one hundred and third meridian, and the symbols used on it made 

no distinction for the predominant metal produced in each camp, 

with the exception of quicksilver.

Since the publication of that map many new districts have been 

added to the lists of producers. The Survey has also had the opportunity to study many regions about which there was little authentic 

information. The present bulletin is a revision and correction of the 

original map, based on the latest available information, with some 

added features which it is hoped will be useful to engineers, geologists, 

and others interested in the metal-mining industry of the Western 

States. *

It is the hope of the writer that those interested will cooperate in 

the correction of mistakes and omissions in both maps and lists by 

notifying the Geological Survey of any errors they may discover. 

44' ; .
PLAN OF THE WORK. 45

The map of each State is published separately in order that it 

may be more easily handled. The scale of each map is about 40 

miles to the inch. The State of California, on account of its large 

size, has been mapped in two parts, the dividing line being an entirely arbitrary one along the county lines south of the Mother Lode 

region. In California there are no mining districts as the term is 

used in other States that is. there are no recorded boundaries to a 

particular district. The Survey has arbitrarily made the subdivision 

into districts for convenience of reference, the mines in a certain 

locality or near a particular town or camp being included in one 

district.

The location of the mining district is indicated on the maps by a 

symbol and a number. The different symbols indicate as far as possible the most important metal produced in each camp. This classification, however, was not always possible, as in some districts several 

metals are of equal importance, and other districts are in the 

prospect stage and their predominant metals are not certain or are 

unknown.

The number with each symbol refers to the list of the districts 

printed on the margin of each map and to the bibliography of that 

State. These lists are arranged alphabetically by counties and each 

map has one consecutive series of numbers.

The map of each State is accompanied by a few pages in which more 

information is given than can be shown on the map. This consists 

of the following items:

1. A number, which corresponds to the number given on the map.

2. The name and subnames of the district.

3. A list of the abbreviations for the metals produced in the camp, 

in the order of their importance. In this list the following abbreviations are used for the different metals:

Au......Gold.

Ag........Silver.

Cu..... .Copper.

Pb.......Lead."

Zn... . . .Zinc.

Hg..... .Quicksilver.

Fe......Iron.

Or....... Chromium.

Ti.......Titanium.

Mn.... .Manganese.

Ni.......Nickel.

Co.......Cobalt.

W....'. .Tungsten.

Sb...... Antimony.

As....... Arsenic.

Bi. .....Bismuth.

U... . . . .Uranium.

V. . '. . . . . .Vanadium.

Mo . . ...Molybdenum.

Pt....... Platinum.

Pd...... Palladium.

The last 12 metals are classed as rare, and where they are the most 

important metals the district is shown on the map as a rare-metal 

district. Metals found in the district but of relatively slight importance are indicated by the appropriate abbreviations in parentheses.

For some districts the list of metals produced is followed by "PI," 

signifying that the production is largely from placer mines, or by "PI 

and D" or " D and PI," signifying that the production is from both deep 

and placer mines, the more important source being placed first. In
46 MINING DISTRICTS OF WESTERN" UNITED STATES.

all districts not marked in this way the production is derived from 

deep mines.

4. The shipping point of the camp, with the distance and direction of 

the camp from it and the railroad on which it is located for example, 

"14 miles NNE.-Winnemucca, S. P. R. R." The distance is estimated from a town in or from the center of the mining district, and 

where possible is the number of miles along the route followed by 

the United States mail. It is entirely possible and in many cases 

probable that there may be some shorter means of approach to the 

camp than that given, but some uniform method had to be adopted 

for the measurement of distances. Many of the distances given do 

not represent the distances as measured on the map, because roads 

are winding and a mail route may touch several other towns in its 

course to a given locality.

5. A statement of the geologic formation of the region, intended 

to give simply a general idea of the rocks in which the deposits occur. 

The attempt has been made to name the oldest rocks first, using the 

terms pre-Cambrian schists, granite, or complex. The term complex is used in districts where schist, gneiss, and granite are found 

in intimate association. The Paleozoic or Mesozoic limestones, 

slates, quartzites, etc., are all combined under the terms Paleozoic 

or Mesozoic sediments. Intrusive rocks are said to "cut" the older 

formations, and volcanic flows "cap" the other formations. Where 

the relation is not known only the names of the rocks are given, as 

Paleozoic sediments, granite, andesite. In placer districts the gravels 

have been classed as follows:

Stream gravels, those of the present stream channel.

Terrace gravels, those of the present stream but found above the present level of 

the stream.

Beach gravels, confined to the shores of the Pacific Ocean. 

Glacial gravels, moraines and outwash from the glaciers. 

Tertiary river gravels, like the buried channels of the Sierra Nevada in California.

6. The kind of deposits found in the region. No attempt has 

been made to discuss the deposits; simply their general character 

is mentioned in the belief that it may be of use. The following terms 

have been used with the meanings indicated, which are sanctioned 

by the United States Geological Survey:

Vein. A single body of minerals occupying or following a fissure, both walls of 

which generally, though not invariably, are well defined. Where several veins are so 

closely spaced that the ground between them becomes in places ore bearing and 

in its whole width constitutes an ore body the assemblage is called a lode. In this 

bulletin the term vein is used for both veins and lodes.

Contact-metamorphic deposits. Ore deposits which occur at or near the contacts of 

intrusive rocks with sedimentary beds and which carry minerals characteristic of contact metamorphisrri, such as garnet, pyroxene, and epidote.

Replacement deposits. Masses of ore and gangue formed by the alteration of limestone, dolomite, and other rocks. Usually irregular in form and in many places 

grading into country rock.

Disseminated deposits. Deposits containing ore minerals scattered throughout the 

rock, such as chalcocite occurring in grains through granite porphyry. The term 

"impregnations" is sometimes applied to deposits of this type.

Stockwork. A deposit consisting of a complex system of small fissure veins.

Lenses. Roughly tabular bodies which diminish in size vertically and horizontally.

7. A bibliography of Survey publications relative to the district. 

It is fully realized that many articles bearing on the metal industry 

which appear in mining, engineering, and scientific journals are of great

value and should be included in any complete bibliography of the 

mining industry of the United States. The great mass of literature 

bearing on the subject of mining and the relatively short time available for this revision and compilation made it necessary to limit the 

publications listed, except as stated below, to those issued by the 

United States Geological Survey. These consist of several series, 

which are indicated by the following abbreviations:

This interpreted means: The deep mines of the Organ district, 

which is numbered 9 on the map of New Mexico, produce lead, silver, 

and copper, lead predominating. The central part of the district is 

15 miles northeast of the shipping point, Las Cruces, on the Atchison, Topeka & Santa Fe Railway, with which it is connected by stage. 

The region is underlain by Paleozoic sediments intruded by quartz 

monzonite. The ores occur in veins, in contact-metamorphic deposits at the contacts of the sediments and intrusive rock, and as 

replacement bodies in the sediments. Notes on the district are given 

on pages 74 to 86 of Bulletin 285 of the Geological Survey, published 

in 1906.. (Other Survey publications on this district are cited in the 

list on p. 230.)

The Thirty-second Annual Report of the Director of the Survey 

contains two maps showing the areas covered by geologic and topographic surveys. Plates I and II are adapted from these maps and 

show what has been accomplished by the Survey in the mapping 

and study of the geology of the Western States. Plate I shows the 

areas covered by topographic surveys. In this work the unit of survey is a quadrangle 15 minutes, 30 minutes, or 1 degree in extent 

each way, covering an area of one-sixteenth, one-fourth, or one

iln the series of bulletins entitled "Contributions to economic geology" and in the volumes of 

Mineral Resources are given bibliographies on the several metals.

square degree. A quadrangle is designated by the name of some 

well-known place or feature in it. The unit of publication is an atlas 

sheet 16£ by 20 inches, and each sheet is a topographic map of one 

quadrangle. As the atlas sheets are uniform in size, the greater the 

area covered the smaller the scale of the map. The scale of the 1- 

degree sheet is 1:250,000, that of the 30-minute sheet is 1:125,000, 

and that of the 15-minute sheet is 1:62,500. The names of adjoining 

quadrangles for which sheets have been published are printed on the 

margins. The cultural features, such as roads, railroads, cities, and 

towns, as well as all lettering, are shown in black; the water features 

in blue; the features of relief hills, mountains, etc. by brown contour lines. The contour interval varies with the scale of the map 

and the relief of the country. Some maps of areas that are economically important are not in conformity with the general scheme outlined above.

"Index maps" on a scale of about 40 miles to the inch, showing the 

location and names of quadrangles represented by published topographic sheets, also names and numbers of geologic folios, have been 

prepared and may be obtained free on application to the Director of 

the Survey at Washington. As it is impossible to show distinctly 

the names of the quadrangles on Plate I, the areas covered by index 

maps are indicated by heavy lines and by numbers which correspond 

to those in the subjoined list:

	Form No.

1. North and South Dakota................................. 9-323 q

2. Montana, Idaho, and Wyoming............................ 9-323 k

3. Oregon and Washington.................................. 9-323 o

4. Texas and Oklahoma..................................... 9-323 j

5. Colorado and New Mexico............................... 9-323 m

6. Utah and Arizona........................................ 9-323 1

7. California and Nevada.................................... 9-323 n

The topographic maps are sold at 5 cents a sheet of standard size, 

or $3 a hundred if at least 100 are ordered at one time. Prepayment is required, and may be made by money order payable to the 

order of the Director of the United States Geological Survey, or in 

stamps or cash the exact amount.

Plate II shows the areas covered by geologic surveys. The numbers 

refer to the list of folios, professional papers, and monographs on the 

page facing the plate.

Geologic maps of the quadrangles covered by the topographic maps 

are generally published in the form of folios. On these maps the 

areal geology, underground structure, and mineral deposits are 

represented by colors and patterns. Each folio contains other maps, 

descriptive text, etc. The price of folios is 25 cents each, as a rule; a 

few that are unusually large are sold for 50 cents. A general circular on geologic folios may be had on application.
52 MINING DISTRICTS OF WESTERN UNITED STATES.

Professional papers are distributed free of charge on application 

to the Director of the Geological Survey, It sometimes happens, 

however, that they are out of stock; in that case they can usually 

be obtained from the Superintendent of Documents, Government 

Printing Office, Washington, D. C., at a nominal cost. Monographs 

are sold at the prices indicated in the list.

It is impossible to indicate the areas described in the other publications of the Survey. Those which deal particularly with mining are 

"Mineral Resources" and some of the bulletins. A complete list of 

Survey publications, revised quarterly, may be had on application 

to the Director.

CLASSIFICATION OF MINING DISTRICTS.

Fourteen States west of the one hundred and third meridian are 

represented in this report as producers of gold, silver, copper, lead, 

zinc, quicksilver, iron, chromium, manganese, and the rare metals.

In these States there are more than 1,479 mining districts recognized by the United States Geological Survey, that number being 

shown on the maps. Some districts are not shown owing to lack 

of knowledge or lack of space. The scale of the map limits the number of mining districts which can be shown as distinct units. In 

Gilpin County, Colo., there are about 12 districts, which have been 

grouped into three on the map. The Mother Lode region of California 

is another example of the necessity for combining districts on account 

of lack of space.

The classification of the districts by predominant metals was made 

on the basis of the production of the districts for the period from 

1902 to 1908, as reported to the United States Geological Survey. 

The following table shows the number of districts in each State 

which produce the several metals, as thus classified:

CLASSIFICATION. 53

This table takes no account of the other metals found in a camp. 

In most regions several metals are produced, and in many districts 

it is difficult to say which is the most important product. Where 

there are few mines the production of one of them may greatly 

influence the classification. For instance, in a copper camp one 

producer may obtain a large amount of gold from his ore. In case 

this gold value exceeds the value of all the copper produced in the 

-camp it would be classed as a gold district, even though it is generally 

spoken of as belonging to the copper class. The silver camps are 

particularly open to question, for there are few mines producing 

principally silver, yet in 151 districts in the Western States silver has 

a greater value than the other metals produced. The table is inserted 

for the reason that it gives the number of districts in each State in 

which one metal has a greater value than the others produced.

The above statement is applicable to the tabulated statements by 

counties for each State.

For a truer record of the relative importance of the metals produced by the mining districts of the Western States the reader is 

referred to the volumes of " Mineral Resources" published by the 

United States Geological Survey.
ARIZONA.

In 12 counties of Arizona there are 136 mining districts. Of these 

the predominant metal is unknown in 3, and in 1 tungsten minerals 

are produced exclusively; 67 districts produce more gold than any 

other metal, 46 more copper, 11 more silver, and 7 more lead. Quicksilver is recovered in 1 district.

CALIFORNIA, NORTHERN COUNTIES.

The State of California maintains a Bureau of Mines, from which 

a large number of reports dealing with the mining industry of the 

State have come. These reports contain much information relative 

to the mining districts which has not been listed in this bibliography.

In the 31 northern counties of California there are 222 areas called 

mining districts by the United States Geological Survey. In 178 

of these districts gold is the principal metal produced; in 16 districts 

quicksilver, in 14 iron or chromium, in 13 copper, and in 1 silver.

Distribution of the predominant metals produced in the mining districts of the northern

counties of California.

COLORADO.

In 35 counties of Colorado there are 132 mining districts, as shown 

by Plate VI. This is not accurate in that in Gilpin and Clear Creek 

counties and some other localities the mining districts are small and 

several have been combined under one symbol and number. In 5 of 

the 132 districts the predominant metal is unknown, in 1 zinc is the 

most important product, in 1 iron, in 8 rare metals, in 60 gold, in 21 

silver, in 20 copper, 'and in 16 lead.

NEVADA.

In Nevada there are 182 mining districts in the 15 counties credited 

with the metallic wealth of the State. In 105 of these districts 

gold is the most valuable metal produced, in 38 silver, in 17 copper, 

in 14 lead, in 2 tungsten, in 1 iron, in 1 manganese, and hi 1 zinc. 

Quicksilver was formerly mined exclusively in one locality. Two 

districts in the State are classed as uncertain that is, the predominant metal is not known.

in which metal mining is carried on to any extent. Eleven districts 

are known to the Geological Survey. Four of these produce silver 

as the predominant metal, three quicksilver, two copper, one zinc, 

and one tin.

Twenty-one counties of Utah contain 86 mining districts which 

are producing according to statistics collected by the United States 

Geological Survey. Gold is the predominant metal in 22 districts, 

silver in 20, copper in 15, lead in 14, and iron in 6. The predominant 

metal in 6 districts is not certain, and of 3 camps producing rare 

metals 2 have deposits of uranium and vanadium and 1 antimony.

In. the State of Wyoming 11 counties are producers of metallic 

minerals and 36 mining districts are recognized by the United States 

Geological Survey. In 19 of these districts copper is the principal 

metal produced and in 13 gold values predominate. Three districts are assigned to iron, but in one of these chromium is mined 

exclusively. One locality is in the prospect stage and its predominant metal is uncertain.

Distribution of the predominant metals produced in the mining districts of Wyoming.
