Metal Mines of Washington-Preliminary Reportby Robert E. Derkey, Nancy L. Joseph, and Raymond Lasmanis

Each mine or occurrence (record) in the database isintended to stand alone with respect to its content Consequently, some fields in a record contain the same data as
those fields for other nearby mines. The repeated datanormally pertain to or describe the geology of the area as awhole. For example, the text of "tectonic setting" may be
the same for all mines in a given mining district.
We have attempted to make individual category/field
entries as complete as possible. However, where information is unavailable, the field is left blank. For some mines,
information from literature sources is entered as a direct
quotation, especially in unlimited-length text fields.

This report is a preliminary compilation that summarizes the geology and related features of 541 metal mines in
Washington. This volume is an updated revision of producing mining properties described by Huntting (1956) in "Inventory of Washington Minerals-Part II, Metallic
Minerals". For a mine to be included in this data set, it shouldhave produced about $1,000 worth of ore. Much of the
production information included here is from Huntting(1956); however, production statistics, which are commonly incomplete in Huntting, are not significantly improved in this report.
In essence, this is a working document; the database
will be continuously updated as new information is received. If a mine in which you are interested has produced
metal(s) worth at least $1,000 but is not included here,
please let us know. If you can supply appropriate production
data for this mine, we will include the mine in the databaseand future versions of this report. In addition, if you finderrors in this report or have new information about any
included mine, please contact us. Send your comments oradditions to:Site Name - The first entry of a site's record is the best
known or most recent name of the mine, mineral deposit,
or mining district This is referred to tas the primary sitename. Sites are presented in alphabetical order by primary site name within each county (also presented inalphabetical order). The primary site name is accompanied by a unique site number which will be used to
identify mines on map plots of this inventory data set.
Alternate Names - All other names by which the mine has
been known. See the Appendix at the back of this reportfor a listing of these alternate names, along with theprimary site name, site numer and county.
District - The mining district(s) in which the mine is situatedCounty - The county in which the mine is located (See Fig.

Longitude - The longitude of the mine location. This information is generally obtained by digitizing from the primary quadrangle(s).

The information in this report can be made available on
disc. Contact R. E. Derkey for more information.
EXPLANATION OF INFORMATION•This inventory of Washington mines is a collection ofgeologic and mineral deposit information that has beenentered into a computer database program called GS MODS(Johnson, 1987). All accumulated information for a single
mine constitutes one record in the database. A category
within a record, such as "ore controls", is termed a field.
Two types of fields make up each record. The first typerequires entry of names or abbreviations, such as for "oreminerals" or "commodities", and results in a listing. The
other type of field allows insertion of an unlimited amountof text or data, including pertinent information from literature sources, the reference, and pages cited.

Age - Host rock age. Entries here correspond sequentially to the listing of host rock names.
Associated Igneous Rock: Description - A brief description of igneous rocks genetically associated with themineraliz.ation. Because the age of relation of igneousrock to mineraliz.ation at a mine is not always known, alligneous rock near a mine site may be included in thisentry. This entry is a list if two or more igneous units areassociated with the mineraliz.ation.
Age - The age of the associated igneous rock(s). Thismay be a listing, corresponding sequentially to thelisting of the associated igneous rocks.
Commodities - The known commodities at the mine. The
chemical symbols for elements and acronyms for commodities are listed at the top of the facing page.
Ore Minerals-All ore minerals known to occur at the mine.
The minerals are listed in generally decreasing order ofSection, Township, and Range - The section, township,and range location for each mine. For many mines, thepoint selected is the center of a cluster of adits and/or
shafts. If the location of a 12.rincipal adit or shaft is known,that point is entered. If a mine portal is distant from anunderground deposit, then a point directly over the deposit is selected.
Location - Any information that will assist in locationof the mine. Some of this information may refer tofeatures that are not shown of a topographic map
but that may be helpful.
Host Rock: Name - The geological units, sequences, orformations in which the mineraliz.ation occurs. This information is generally taken from available geologic
maps.
Lithology - The host rock lithology. This is given in thesame order as that for the host rock names. The
lithology, if taken from the explanation of a geologic map, may differ from lithologies given in the
Ore Controls field for a mine. The lithology asrecorded in Ore Controls is commonly from an

PRODUCTION: The Blewett Iron deposit has not produced but has been extensively evaluated as an iron resource(Huntting, 1956, p. 194).

•

TECTONIC SETTING: Several iron-nickel-chromite lateritic deposits overlie serpentinized ultramafic rocks (Broughton,
1943, p. 9-13) of the Ingalls Complex, a Jurassic ophiolite complex (Miller, 1985, p. 27; Tabor and others,
1982, p. 5-6).
ORE CONTROLS: The Blewett iron deposits are laterite deposits. Many of the laterite deposits were eroded from their
nearby source area and deposited to form a sequence of conglomerates and fine-grained, iron-rich beds. The
iron and chromium were from iron in silicate minerals, magnetite-hematite, and chromite weathered fromthe serpentinite. Nickel is from silicates released during laterization (deep weathering) of the serpentinite(Broughton, 1943, p. 10).
GEOLOGIC SETTING: The laterites were transported and deposited beneath or as basal beds of the Eocene Swauk
Formation. Lamey (1950, p. 1) tentatively interprets the conglomeratic iron beds as landslide debris or
mudflow deposits.
COMMENTS: Iron deposits of the Blewett area were evaluated in the 1940s by the Washington Division of Geology.
This was followed by extensive drilling by the U.S. Bureau of Mines (10 holes, 2,395 ft) and metallurgicaltesting. (See references for specific reports.) This evaluation showed reserves of 46,000 tons at a grade of
0.88% Ni, 2.5% Cr20.3, 32% Fe, and 8,000,000 tons at a grade of 0.39% Ni, 0.85% Cr20 3, and 11.53% Fe(Huntting, 1956, p. l 94 ).

PRODUCTION: Production records for the various mines of the Blewett camp are incomplete; however, the value of
production totals several hundred thousand dollars. Many of the mines have some recorded production, but
a production figure for the entire camp is not available (Huntting, 1943, p. 9-14; 1956, p. 109-117).
TECTONIC SETTING: The Jurassic Ingalls Complex, the host rocks of the Blewett Camp deposits, is a disrupted, Late
Jurassic ophiolite complex. Igneous activity in the area includes the Late Cretaceous Mount Stuart batholithand intrusive rocks of early magmatic activity of the Cascades magmatic arc (Miller, 1985, p. 27; Taborand others, 1982, p. 5-6).

•

ORE CONTROLS: Where the veins cut gneissic rocks, the gangue is chiefly quartz with minor amounts of calcite, butwhere the veins cut serpentinite, the amount of calcite increases relative to quartz. The most productive
veins are in Culver Gulch and trend N75W. The ore is generally of low grade. Most production was fromhigh-grade ore shoots (Huntting, 1943, p. 8).
GEOLOGIC SETTING: Most of the mineralization of the Blewett Camp is in veins cutting serpentinite of the Ingalls
Complex (Hawkins Formation in Weaver, 1911, p. 31-34). Other veins are in metasedimentary and metavolcanic rocks of the Complex; however, veins in the serpentinite are generally more productive than those in
the other rocks (Weaver, 1911, p. 29-33).
COMMENTS: Mines of the Culver Gulch area are here combined into a single entry called the Blewett Camp deposit.

PRODUCTION: The Cannon mine began production in the mid 1980s and is producing at the present time (1990).
Production for 1989 was 150,420 oz of Au and 302,731 oz of Ag (Joseph, 1990, p. 19).
TECTONIC SETTING: The Cannon mine is situated in the Chiwakum graben (Eocene}, a north-northwest-trending
right-lateral, strike-slip graben bounded by the Entiat fault zone on the east and the Leavenworth fault zone
on the west (Ott and others, 1986, p. 426).
ORE CONTROLS: Mineralization consists of widely spaced veins, veinlets (stockworks), and disseminated minerals in
brecciated rocks. By far the most abundant ore mineral is electrum. The highest ore grades are in quartzchalcedony-adularia-calcite veins. Two sets of fractures control vein mineralization: early veins in fractures
radial to fold hinges, and veins in faults that cut the earlier radial faults-veins (Ott and others, 1986, p. 425,
432). Electrum in banded veins is found near the vein margin, and pyrite, where present, is found near thecenter of the vein. The mineralization occurs in sandstone and siltstone beds that were silicified prior to
brecciation and deposition of quartz veins and veinlets. The quartz veins range to as much as 4 ft wide andare irregular and discontinuous. Most veinlets are less than 1 in. wide.
GEOLOGIC SETTING: An unnamed sandstone unit and the overlying Eocene Chumstick Formation host mineralization
at the Cannon mine. Mineralization occurs in favorably altered (commonly silicified) horizons of these
Tertiary (Eocene?) arkosic sandstone units (Ott, 1988, p. 20-23). Ore bodies extend from the surface todepths of more than 900 ft.
COMMENTS: This deposit is currently (1990) being mined as a joint venture project of Asamera Minerals Inc. andBreakwater Resources Ltd.

•UNPUBLISHED INFORMATION: Information gained from a tour of the Cannon mine lead by mine geologist M.

PermianPRODUCTION: From 1938 through 1957 a total of more than 212 million lb of Cu, 40 million lb of Zn, 2 million oz
of Ag, and 600,000 oz of Au were obtained from 10 million tons of ore (McWilliams, 1958, p. 3) .
TECTONIC SETTING: The deposit formed in an island arc to back arc basin environment with deposition of both maficand siliceous volcanic rocks. Nonvolcanic rocks, including marble, are also prevalent near the mine (Nold,
1983, p. 945-948).
ORE CONTROLS: The orebody is lens shaped and has a length downdip of about 2,000 ft and a thickness of as muchas 100 ft. The zoned orebody ranges from a zinc-rich footwall to a copper-rich hanging wall, indicating theorebody is overturned. Foliation of the schist parallels bedding (Nold, 1983, p. 945-948).
GEOLOGIC SETTING: The mine occurs within a series of schists, gneisses, and amphibolites, which are part of Caterand Crowder's (1967, geol. map; Cater, 1982, p. 6-7) Late Paleozoic "rocks of the Napeequa River area".
The orebody is surrounded by sericite-quartz schist occurring within the shists, gneisses, and amphibolite
sequence (Nold, 1983, p. 944-948). The Holden mine is believed to be Kuroko-type, volcanogenic massive
sulfide deposit (R. E. Derkey). Kuroko-type features include the zoned, massive-sulfide orebody (zoned
with copper-rich base and zinc-rich top) conformable with bedding, enclosure in sericite schist (altered felsic
tuffs), and presence of anhydrite.

EocenePRODUCTION: Broughton (1943, p. 16-19) reports 59,850 tons of exposed, 45,720 tons of probable, and 435,850 tonsof possible ore reserves in three areas.
TECTONIC SETTING: Iron-nickel-chromium deposits (residuum of weathering products) overlie serpentinized ultramafic
rocks (Broughton, 1943, p. 9-13) of the Ingalls Complex, a Jurassic ophiolite complex (Miller, 1985, p. 27;
Tabor and others, 1982, p. 5-6).
ORE CONTROLS: The Negro Creek Iron deposit is one of several Blewett-area iron deposits. These deposits are aresiduum of weathering products developed over iron-, chromium-, and nickel-bearing serpentinized peridotite. Iron and chromium are found in the minerals magnetite, hematite, and chromite weathered from theserpentinite. Nickel silicates develop during laterization (extended weathering) of the serpentinit.e. The ironbeds occur in a series of thick conglomerates and associated rocks (Broughton, 1943, p. 10).

•GEOLOGIC SETTING: Some of the laterites were reworked prior to deposition of the Eocene Swauk Formation. Lamey(1950, p. 1) tentatively interprets the conglomeratic iron beds as landslide debris or a mudflow deposit.

PRODUCTION: Produced $100 prior to 1897 (Huntting, 1956, p. 181). Platinum was also found about 6 mi upstream
from the mouth of Negro Creek. Only a small amount (reportedly) was produced (Huntting, 1956, p. 281).
TECTONIC SETTING: Alluvial deposits containing heavy minerals.

•

ORE CONTROLS: Heavy minerals were concentrated by stream action. Several pieces of nearly pure chromite weighing
about 3 lb each were reported (Huntting, 1956, p. 37) from Negro Creek in the SWl/4 sec. 12, 22N, 16E .
GEOLOGIC SETTING: Negro Creek drains an area containing several gold and chromite deposits of the Blewett Camp.
Bedrock of the area includes ultramafic rocks of the Ingalls Complex (Tabor and others, 1982).

PRODUCTION: Huntting (1956, p. 181) reports the area has produced.
TECTONIC SETTING: Alluvial deposits containing heavy minerals.
ORE CONTROLS: Heavy-mineral concentration by stream action. Huntting (1956, p. 181) reports the gold is coarse.
GEOLOGIC SETTING: Division files contain a mineral examination report prepared for an application to patent placer
claims in sec. 13, 22N, 17E. This property is near the mouth of Allen Creek, which appears to be thesouthern limit of placer gold on Peshastin Creek. The creek drains northward past several mines between
Allen Creek and Negro Creek. This is the apparent extent of favorable ground for placer deposits on Peshastin
Creek.

PRODUCTION: Produced more than 15,000 tons of ore during intermittent periods from 1930 to 1940 (Huntting, 1956,
p. 50).
TECTONIC SETTING: Ore at the Red Mountain mine was emplaced during or following major deformation andmetamorphism of the host rocks. The extent of metamorphism of the orebody, if any, is not reported (Caterand Crowder, 1967, geol. map).

ORE CONTROLS: Mineralization is most extensive in the brecciated zone between Swakane Biotite Gneiss and diorite.
Sulfide minerals are chiefly pyrrhotite and chalcopyrite. Scheelite occurs as disseminated grains, veinlets,
and small masses in the sulfides (Culver and Broughton, 1945, p. 14-15).
GEOLOGIC SETTING: Radiometric ages on zircons from the Swakane Biotite Gneiss indicate an age for metamorphismof 415 m.y. and formation ages of 1,650 m.y. or more (Mattinson, 1972, p. 3773). The age and nature of
the diorite are unknown.

PRODUCTION: More than $170,000 by 1930 and small amounts in 1933, 1934, and 1940 (Huntting, 1956, p. 116).
TECTONIC SETTING: The Chelan Complex formed in Late Cretaceous and consists of high-grade metamorphic rocks
that were intruded by numerous tonalitic plutons. These massive tonalite plutons were again metamorphosedin latest Cretaceous and earliest Tertiary time (Tabor and others, 1987, p. 5-6). The relation between
metamorphism and emplacement of the quartz veins is unknown.
ORE CONTROLS: Two oxidized quartz veins, 3 to 12 in. in width, in decomposed gneiss (Huntting, 1956, p. 116).
GEOLOGIC SETTING: The rocks of the Chelan Complex (Hopson and Mattinson, 1971, p. 13; see also map of Taborand others, 1987, p. 5-6) consist of massive and gneissic tonalite and migmatite near Chelan and along Lake
Chelan and banded gneiss and banded migmatite gneiss along the Entiat River.

EocenePRODUCTION: See description for individual mines .
TECTONIC SETTING: The Republic district is in the Republic graben, a major intracratonic, volcano-tectonic depression
in northeastern Washington. The graben contains a thick sequence of Eocene volcanic and volcaniclastic
rocks.
ORE CONTROLS: A major hydrothermal system in the Republic district produced a series of epithermal veins cappedby hot-spring (sinter) deposits. The hot-spring deposits formed at paleosurfaces in the Sanpoil Volcanics
prior to deposition of the overlying Klondike Mountain Formation. The majority of the recovered gold andsilver was from the epithermal veins. The veins exhibit features indicative of episodic vein sealing andoverpressuring followed by flashing and precipitation of precious metals, thus forming the characteristic
coloform bands. Geometrically, ore deposits in the Republic district extend from the paleosurface mineralization in hydrothermally altered rocks and sinter downward into epithermal stockworks and hydrothermal
breccias, and farther downward into tightly confined, commonly coloform-banded veins (Muessig, 1967;
Tschauder, 1989).
GEOLOGIC SETTING: Host rocks for gold deposits of the Republic district are dacite and andesite flows, flow breccias,
tuffs and tuff breccias of the Eocene Sanpoil Volcanics (Muessig, 1967, p. 50-51; Tschauder, 1989, p. 242).

PRODUCTION: Produced a small amount of lead, copper, zinc, silver, and gold in 1923 (Huntting, 1956, p. 51). Produced
1,500 tons of ore in 1973 (Moen, 1976, p. 100).
TECTONIC SETTING: Paleocene to Eocene granitic rocks intrude metamorphosed Ordovician? rocks (Joseph, 1990,
geol. map).

•

ORE CONTROLS: Mineralization is in 4-6-ft-wide quartz veins in schist. The ore occurs as lenses in three of the
exposed veins. One ore shoot is 50 ft long; another is 100 ft long (Huntting, 1956, p. 51).
GEOLOGIC SETTING: Ordovician? sedimentary rocks of the Covada Group host quartz veins at the Addison mine.
The sedimentary rocks are near Paleocene to Eocene granodiorite. Numerous Eocene hypabyssal dikes arefound in the area (Joseph, 1990, geol. map, p. 6-7).

PRODUCTION: Minor shipments were made in the early 1900s (Moen, 1976, p. 101) .
TECTONIC SETTING: Paleocene to Eocene granitic rocks intrude metamorphosed Ordovician? rocks in the Keller
graben (Joseph, 1990, geol. map, p. 12).
ORE CONTROLS: Mineralization is in silicified schist, which is cut by porphyry. Ore occurs as pockets and sparse
disseminations in small quartz veinlets (Huntting, 1956, p. 290).
GEOLOGIC SETTING: Joseph (1990, geol. map) shows the mine is in porphyritic granodiorite of Manila Creek. Because
Huntting (1956, p. 290) notes the mine is in schist, the area must be a small roof pendant in the Paleocene
to Eocene granitic body. The area also contains numerous dacite dikes (Joseph, 1990, geol. map).

EocenePRODUCTION: The first gold-silver dore was poured (1990) from the jointly operated Overlook and Kettle mines .
Anticipated production for the first year is 110,000 oz of Au, with the majority to come from the Overlook
deposit (Joseph, 1990, p. 20).
TECTONIC SETTING: Epithermal deposits are found in the Sanpoil Volcanics and are similar to deposits of the Republicdistrict.
ORE CONTROLS: The deposit exposed in the mine is in the zone just below the sinter zone of a typical hot-spring
deposit. Veins are associated with some dikes (Walt Hunt, personal commun., 1990; Tschauder, 1989).
GEOLOGIC SETTING: Host rocks for the Kettle mine are the same as for deposits of the Republic district and are
dacite and andesite flows, flow breccias, tuffs, and tuff breccias of the Eocene Sanpoil Volcanics (Muessig,
1967, p. 50-51; Tschauder, 1989, p. 242).

manto-like massive replacement
PRODUCTION: Shipped 3,249 tons of oxidized ore in 1907 and 7,000 tons of ore prior to 1940 (Huntting, 1956, p.
52).
TECTONIC SETTING: Permian-Triassic metasedimentary and metavolcanic rocks are preserved in the Republic graben
east and northeast of Republic. They are locally cut by Eocene epizonal plutons and associated sills anddikes (Muessig, 1967, geol. map).
ORE CONTROLS: Iron-gold mineralization is manto-like and occurs as replacement bodies in limestone. One of thesebodies is 100 ft long, 100 ft wide, and 25 ft thick. In places the ore bodies consist of nearly pure magnetite(Huntting, 1956, p. 52). Currently (1990), some of the iron bodies (magnetite, pyrite, pyrrhotite) are being
mined for gold (Tschauder, 1989, p. 245).

•

GEOLOGIC SETTING: The Key East deposit is in Permian-Triassic limestone, dolomitic limestone, argillite, andgraywacke. The ore bodies lie next to a network of dikes, sills, and intrusive bodies of the Scatter Creek
Rhyodacite (Muessig, 1967, p. 113).
COMMENTS: The Key East deposit (formerly the Copper Key) and the nearby Key West deposit are identified areasthat contain gold reserves. These deposits are about a mile northeast of the Overlook mine, which is now(1990) being mined by Echo Bay/Crown Resources.

dacite in a zone 50 ft wide in the hanging wall of an diabase dike dipping 30-50 degrees to the east andsoutheast. Company records indicated nearly 250,000 tons of ore containing 1.94% Cu, 0.047 oz/ton Au,
0.204 oz/ton Ag remained in the ground (Huntting, 1956, p. 54).
GEOLOGIC SETTING: The Lone Star and Washington mine is covered by a thick overburden of glacial debris, andfew outcrops of Permian-Triassic greenstone, graywacke, argillite, and limestone can be found in the area.
The diabase dike in the mine may be similar to alkalic rocks exposed on Shasket Creek (Parker and Calkins,
1964, p. 87).

PRODUCTION: Produced at least 120 tons of ore. A handpicked ore shipment ran 25% Sb. Three carloads shipped ran
53-57 oz/ton Ag and about 0.2 oz/ton Au (Huntting, 1956, p. 291).
TECTONIC SETTING: Jurassic to Cretaceous granitic to granodioritic rocks intrude metamorphosed Ordovician? rocks(Joseph, 1990, geol. map, p. 34).
ORE CONTROLS: The deposit is a mineralized zone of silicified granodiorite breccia, 8 to 30 ft wide, that occurs
adjacent to an alaskite dike. The breccia is cemented by quartz and ore minerals. Mineralization in the
breccia zone is as much as 150 ft wide (Huntting, 1956, p. 291). Mineralization is accompanied by strong
alteration and occurs on both sides of the alaskite dike. On the west side of the dike, mineralization isprincipally antimony and on the east side principally gold and silver (Purdy, 1951, p. 68-71).

•

GEOLOGIC SETTING: The Longstreet mine is in Jurassic to Cretaceous granite to granodiorite of the Meteor area

PRODUCTION: There was an unknown amount of Pb, Cu, and Ag production from the Meadow Creek (Mount Tolman)mine in 1935 and 1936. The Golden Cord and the Ophir mines also produced, but no records are available.
TECTONIC SETTING: .,..he Keller Butte pluton, which hosts the Mount Tolman deposit, is situated on the northwest
projection of the N65-80W-trending Lewis and Clark structure (Osborn fault in Idaho). Foliation and mineral
grains in the pluton trend N65-75W. Emplacement of the multi-phased pluton in this N65-80W trend resulted
in the Cu-Mo deposit being elongate N68W.
ORE CONTROLS: The Mount Tolman deposit is 1 mi wide in a north-south direction, 2 mi long, and 1,200 ft thick.
During crystallization of the last phase of the interior zone of the host quartz porphyry, a minimum of five
periods of fracturing and concurrent mineralization took place. Each period affected the same rocks, andeach episode of mineralization added to the distinctive vertical zonation: quartz with molybdenite predominate
in the center, while chalcopyrite, pyrite, and sphalerite increase away from the core. Post-stockwork veinssurrounding the Mount Tolman deposit cut the molybdenite-bearing fractures. These veins contain galena,
sphalerite, and chalcopyrite. Drilling, underground exploration, and bulk sampling have outlined proven andprobable reserves of 2.4 billion tons of ore with an average grade of 0.093% MoS.2_and 0.09% Cu; the cutoff
grade used was 0.048% MoS 2• Metallurgical testing resulted in recoveries of 8Yfo of the molybdenite and
80% of the chalcopyrite. The oeposit represents a recoverable reserve of 1.9 million tons of MoS 2 ~d 1.73
million tons of copper. A mine plan designed by AMAX would have recovered 727,260 tons of MoS 2 and662,400 tons of copper. The AMAX plan was based on mining approximately 900 million tons ot ore
averaging 0.10% MoS 2 and 0.09% Cu and a waste to ore ratio of 0.83:1. This ranks the Mount Tolman
deposit as the third or fourth largest molybdenum deposits in the world after Climax and Quartz Hill.
Whole-rock analyses indicate the Mount Tolman rocks contain 0.3-0.5% Ti02, and if recoverable, the deposit
could produce titanium.
GEOLOGIC SETTING: The Mount Tolman deposit is in the Paleocene-Eocene Keller Butte pluton. Post-ore faults
displaced the deposit and resulted in ore dilution. These faults strike N65W, N20E, N45E, and N35E.
Post-ore dikes strike N60-75E and have steep northwest to vertical dips. Post-ore faulting and dike activity
is probably related to development of the Republic graben.

68•

Ferry•COMMENTS: The Mount Tolman deposit is owned (1990) by the Colville Confederated Tribes. Prior to tribal acquisitionof the land, numerous mines were developed in search of silver ore. Mine adits were driven by: Consolidated
Mines and Smelting Co., Ltd. (adits include the Iconoclast, Golden Cord, Advance, Silver Ridge, California,
Umatilla, Walla Walla, Jumper, Handspike, and Dewey); the Meadow Creek mine (adits include the Blue
Bird, Abe Lincoln, King Richard, Blevins, and Sanpoil); the Rover-Bonanza group (adits include the Golden
Rule, Golden Chariot, and North Star); and also the adits Bobbie Jay, Josie, Ophir, Byrne, Addie B, Humboldt,
Pole Pick, and adits by Illinois Copper and Silver Mining and Milling Co. Bear Creek Mining Co. leased
the property from the Colville Business Council in July of 1964. From 1964 to 1976 Bear Creek completed
45,000 ft of drilling and drove a 650-ft adit at elev. 3,000 ft. AMAX Exploration, Inc. signed an agreementin 1978 and undertook a major 2-year development program. They completed 386,827 ft of drilling, threeadits totaling 2,160 ft, and metallurgical testing. Drilling costs alone from August 18, 1978, to December
1980 were $10,167,739. AMAX terminated its lease in 1982.

PRODUCTION: The first gold-silver dore was poured (1990) from the jointly operated Overlook and Kettle mines .
Anticipated production for the first year is 110,000 oz; the majority will be from the Overlook deposit(Joseph, 1990. p. 20).
TECTONIC SETTING: Eocene felsic rocks intruded Permian-Triassic metasedimentary and metavolcanic rocks of the
Republic graben (Muessig, 1967, geol. map).
ORE CONTROLS: Gold and silver mineralization at the Overlook deposit occurs in manto-like replacement bodies ofmagnetite, pyrite, and pyrrhotite in limestone and as disseminated and stockwork bodies overlying themassive, iron-rich horizon in the limestone. Currently (1990), this deposit is being mined for its gold-silver
mineralization (Tschauder, 1989, p. 245).
GEOLOGIC SETTING: The Overlook deposit is in Permian-Triassic limestone, dolomitic limestone, argillite, andgraywacke. The ore bodies lie next to a network of dikes, sills, and intrusive bodies of the Scatter Creek
Rhyodacite (Muessig, 1967, p. 113).

PRODUCTION: Produced $40,000 worth of ore prior to 1903; ore was shipped from the dump in 1935 (Huntting, 1956,
p. 295) .
TECTONIC SETTING: Sequence of Eocene volcanic rocks in the Toroda Creek graben (Pearson, 1967, geol. map).
ORE CONTROLS: Mineralization is in a well-defined 1-6-ft-wide quartz vein filling an irregular fracture in phonolite.
The vein is sparsely mineralized and low grade except in the zone of secondary enrichment, which extends
from the surface to a depth of about 150 ft (Huntting, 1956, p. 295). Wall rock adjacent to the vein is
brecciated and sheared, and the breccia is cemented by quartz, chlorite, and fluorite. Ore was mined fromore shoots in the zone of secondary enrichment (Moen, 1980, p. 70).
GEOLOGIC SETTING: The Zalla M is in flows and breccias of the Eocene Klondike Mountain Formation. The rocks
appear to be rhyolitic in composition, but on close examination, outlines of what appear to be pyroxene
phenocrysts are found. This suggests the rocks are probably altered andesite (Stoffel, 1990, geol. map, p.
l_l; Pearson, 1967, geol. map).

EocenePRODUCTION: Produced approximately 80 tons of ore (Huntting, 1956, p. 258).
TECTONIC SETTING: Host rocks of manganese deposits of the Olympic Peninsula formed at an ocean ridge or in aback arc basin at the active margin of the North American plate (Garrison, 1973; Snavely, 1987, p. 306-309).
ORE CONTROLS: Manganese occurs in discontinuous pods. The mineralization is in a highly siliceous ferruginous
rock, which on a fractured surface shows small veinlets of clear to milky, crystalline quartz (data from
USGS MRDS, 1990). Manganese deposits of the region are associated with spilites (Park, 1942, p. 311-312)
and commonly are found with reddish pelagic limestone interbedded with the basalt. Manganese mineralization
may be either disseminated in replacement bodies or volcanogenic exhalative/diagenetic bodies (Sor~ andGunn, 1967).
GEOLOGIC SETTING: Altered basalt is the principal country rock for the Burnt Hill deposit. Superficial weathering
gives the basalt a yellowish to light-brown color; however, megascopic examination of a newly fractured
surface reveals fine-grained, greenish-gray material (data from USGS MRDS, 1990). The Crescent Formation,
which hosts manganese mineralization on the Olympic Peninsula, consists of Paleocene? and Eocene pillow
basalts compositionally similar to ocean ridge basalts. Associated pelagic limestones were deposited in deep
water (Snavely, 1987, p. 306-308).

TECTONIC SETTING: Host rocks of manganese deposits of the Olympic Peninsula formed at an ocean ridge or in aback arc basin at the active margin of the North American plate (Garrison, 1973; Snavely, 1987, p. 306-309).
ORE CONTROLS: Minor faults and fractures occur in the greenstone. At the mine two small manganiferous ore bodies
are present in siliceous zones in altered basalt. In the upper siliceous zone, the manganiferous area is 6 ft
by 30 ft, and the lower area is 6 ft wide and 22 ft long. The siliceous zone of the lower manganese area isabout 10 ft by 70 ft. Manganese is present as silicates and, in minor amounts, as secondary oxides (datafrom USGS MRDS, 1990). Manganese deposits of the region are associated with spilites (Park, 1942, p.
311-312) and commonly are found with reddish pelagic limestone interbedded with the basalt. Manganesemineralization may be either disseminated in replacement bodies or volcanogenic exhalative/diagenetic

EocenePRODUCTION: Produced in the 1940s (data from USGS MRDS, 1990).
TECTONIC SETTING: Host rocks of manganese deposits of the Olympic Peninsula formed at an ocean ridge or in aback arc basin at the active margin of the North American plate (Garrison, 1973; Snavely, 1987, p. 306-309).
ORE CONTROLS: Basalt in the mine area is locally highly fractured and cut by many minor faults. Manganese depositsof the region are associated with spilites (Park, 1942, p. 311-312) and commonly are found with reddish
pelagic limestone interbedded with the basalt. Manganese mineralization may be either disseminated inreplacement bodies or volcanogenic exhalative/diagenetic bodies (Sorem and Gunn, 1967).

•

GEOLOGIC SETTING: The area is underlain by basalt lava flows and intercalated tuff and red argillaceous limestone;much of the basalt is altered. Pillow basalt is exposed in places. The basaltic flows generally trend northand stand nearly vertical; locally, they are greatly deformed and fractured. Three red limestone beds andintercalated basalts form three or more distinct parallel ridges extending from the Dosewallips River northward
to the top of the divide. Three limestone interbeds in basalt contain lenses of manganese ore, some as muchas 25 ft f}lick. The Crescent Formation, which hosts manganese mineralization on the Olympic Peninsula,consists of Paleocene? and Eocene pillow basalts compositionally similar to ocean ridge basalts. Associatedpelagic limestones were deposited in deep water (Snavely, 1987, p. 306-308).

PRODUCTION: One carload shipped (Huntting, 1956, p. 196).
TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc .
ORE CONTROLS: Ore body is in limy quartzite and is presumably a contact metamorphic deposit. The exposed portion
is a lenticular mass that is 25-30 ft high and 15 ft wide and that exposed approximately 2,000 tons (Huntting,1956, p. 196). Shedd (1924, p. 66) reports the presence of titanium in assays from the Anderson property.
GEOLOGIC SETTING: Tabor and others (1982) map the area as all within granodiorite and tonalite of the Index
batholith. The mineralization presumably occurs in a small roof pendant or included block.

PRODUCTION: Produced 300 tons worth $80,000 prior to 1901. Also produced ore worth a total of $300,000 frommining in 1905, 1908, 1910, 1912, 1913, 1916-1920, 1926, 1928, andl936-1943 (Huntting, 1956, p. 126).
Production from 1905 to 1940 was valued at $220,000 (Moen, 1976, p. 166). Shipments in 1921 averaged
between 21 % and 26% As, 18 and 20 oz/ton Ag, 1.5 and 2.5 oz/ton Au, and 4.5 and 6% Pb (Livingston,
1971, p. 163).
TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.
ORE CONTROLS: Mineralization is in a quartz vein 2-6 ft wide which follows a continuous fissure in granodiorite.
High-grade ore occurs in shoots in the vein (Huntting, 1956, p. 126). The paragenetic sequence is quartz
and tourmaline followed by pyrite and quartz, then quartz and stibnite(?), sphalerite, quartz, tetrahedrite andgalena, chalcopyrite, and calcite (Coats, 1932, p. 19). Arsenolite (a secondary arsenic mineral) is found in
the mine workings (Coats, 1932, p. 17).

•

GEOLOGIC SETTING: The Apex mine occurs in rocks of the Snoqualmie batholith, northern phase, which consists of
granodiorite and tonalite and is light colored, medium crystalline, and mostly equigranular and has
hypidiomorphic texture. The rocks are coarsely jointed and contain biotite and hornblende and locallyclinopyroxene. Age of the northern phase is about 25 m.y. based on interpretation of numerous discordant
K-Ar ages of both hornblende and biotite (Tabor and others, 1982, p. 8).

TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.
ORE CONTROLS: Livingston (1971, p. 140) notes two mineralized zones. The country rock along both zones wasaltered to kaolinite and locally sericite. Argentiferous galena and chalcopyrite are the principal ore minerals;
pyrite is abundant. Huntting (1956, p. 296) reports the alteration and mineralization lie along joints in the
granodiorite. The two main zones are each about 2.5 ft wide.
GEOLOGIC SETTING: The Cleopatra Group of deposits is in rocks of the Snoqualmie batholith, northern phase, which

PRODUCTION: Test stope 25 ft by 35 ft long; ore stockpiled on dump .
TECTONIC SETTING: Part of a northeast-trending belt of en echelon (NW-striking) faults, fractures, and breccia pipes
defining a porphyry copper system.
ORE CONTROLS: The Clipper group consists of seven zones, the Clipper, Pedro, Katie Belle, Hawk, Three Brothers,
Red Face, and Crawford Creek. The group is in a large area of mineralization in which five narrow structuresof higher grade mineralization have been indicated. The mineralization is in shear zones, along fractures,and in veins. One structure, explored by drilling and an adit, was centered on a surface exposure ofmineralization that was 40 ft by 800 ft. Samples collected on the surface there had assay values ranging
from 0.52% Cu to 1.2% Cu and 0.2% MoS 2 . One drill hole had a 69-ft intercept averaging 0.73% Cu.
Copper content of some underground samples ranged from 0.31 %-0.98%. Two samples on the J.T. Claimshow copper and assay 0.015 oz/ton Au, and 0.040 oz/ton Au (see report in the Clipper file). Inferredreserves of 226,800 tons of 0.9 % Cu are reported in Gualtieri and others (1975) for the Clipper zone.
Potential reserves from drilling in the Three Brothers zone are 1.8 million tons averaging 0.7%-0.9% Cu.
GEOLOGIC SETTING: The Clipper deposit is in the Snoqualmie batholith, northern phase granodiorite and tonalitewith biotite and hornblende; locally it contains clinopyroxene. The rocks are light colored, medium crystalline,
mostly equigranular with hypidiomorphic texture, and are coarsely jointed. The northern phase is about 25
m.y. old, on the basis of interpretation of numerous discordant K-Ar ages of both hornblende and biotite(Frizzell and others, 1984, p. 18).
COMMENTS: On the Last Chance claim, a 390-ft adit bearing N40W intersects mineralization from 265 to 310 ft; thearea was stoped. On the Pedro claim, a 10-ft adit was driven in a 50-ft-wide mineralized zone. On the Katie
Bell and Tracy claims, a 15-ft adit and a 100-plus-ft adit were driven. Both the patented and unpatented
claims are owned (1990) by United Cascade Mining Company, Inc. Companies who have explored thedeposit include Anaconda Copper Co., Howe Sound Co., Climax Molybdenum Corp., Anaconda Co., Bear
Creek Mining Co., Cities Services Minerals Corp., Westland Mines Ltd., Natural Resources Development·

PRODUCTION: No production has been recorded.
TECTONIC SETTING: Part of a northeast-trending belt of en echelon (NW-striking) faults, fractures, and breccia pipes
defining a porphyry copper system.
ORE CONTROLS: The Condor-Hemlock is in a northwest-trending mineralized zone. The Condor is located at thecenter of the zone, and the Hemlock is located at the southeast end of the zone. The mineralization is inshear zones, along fractures, and in veins in granodiorite and tonalite. Hydrothermal alteration grades frompropylitic at the surface to quartz-sericite-chlorite to K-feldspar predominating at depth. Pyrrhotite increases
and pyrite decreases with depth. Secondary enrichment of covellite and chalcocite was found in a drill holewhen the West Condor fault was intercepted between 151 ft and 203 ft. This 52-ft intercept averaged
1.66 % Cu, more than 1.0 oz/ton Ag, and $0.75 gold per ton (November 15, 1965 prices). The mineralizedzone has a strike length of 1,000 feet, a thickness of 400 feet, and a depth of more than 400 feet. The
Condor portion of the zone has potential reserves of 25-30 million tons averaging 0.616 % Cu and 0.032% MoS2. Gold and silver values range from $0.40 to $1.25 per ton (October 1967 prices). The Hemlockzone (including part of another zone called the Porter and some adjacent zones) has been tested by 23 drill
holes (total footage unknown) and three adits totalling 3,200 ft. By 1975, potential reserves of 91 million
tons averaging 0.6-0.8% Cu and 0.02-0.05% MoS 2 in the combined Porter and Hemlock zones was indicated(Gualtieri and others, 1975).
GEOLOGIC SETTING: Of the numerous mineralized zones in the Middle Fork Snoqualmie system (Livingston, 1971,
p. 152-153), the Condor-Hemlock contains the best demonstrated reserves. The deposit is open at depth(below 1,495 ft). The Condor-Hemlock zone is in the Snoqualmie batholith, northern phase granodiorite
and tonalite that contains biotite and hornblende; locally it contains clinopyroxene. The rocks are lightcolored, medium crystalline, mostly equigranular with hypidiomorphic texture, and coarsely jointed. The
northern phase is about 25 m.y. old, on the basis of interpretation of numerous discordant K-Ar ages ofboth hornblende and biotite (Frizzell and others, 1984, p. 18).

TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc .
ORE CONTROLS: The deposit consists of small persistent quartz veinlets along joint planes in granodiorite. A silicified
and mineralized zoneas much as 15 ft wide was also noted (Huntting, 1956, p. 127; Livingston, 1971, p.
164). Purdy (1951, p. 87), on the basis of the presence of antimony in an assay result, suggests that theprobable antimony mineral is jamesonite, which is typical of other deposits in the area.
GEOLOGIC SETTING: The Coney Basin deposit is in rocks of the Snoqualmie batholith, northern phase, which consistsof granodiorite and tonalite and is light colored, medium crystalline, and mostly equigranular and has
hypidiomorphic texture. The rocks are coarsely jointed and contain biotite and hornblende and locallyclinopyroxene. Age of the northern phase is about 25 m.y ., based on interpretation of numerous discordant
K-Ar ages of both hornblende and biotite (Tabor and others, 1982, p. 8).

PRODUCTION: Shipped 23 tons prior to 1940 (Huntting, 1956, p. 127). Ore shipped averaged 0.87 oz/ton Au, 9 oz/ton
Ag, and 4% Pb (Moen, 1976, p. 167).
TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.
ORE CONTROLS: Similar to the Apex mine. Consists of two veins, one averaging 3 ft wide over a distance of 900 ft(Huntting, 1956, p. 127).
GEOLOGIC SETTING: The Damon and Pythias mines are in rocks of the Snoqualmie batholith, northern phase, which
consists of granodiorite and tonalite and is light colored, medium crystalline, and mostly equigranular andhas hypidiomorphic texture. The rocks are coarsely jointed and contain biotite and hornblende and, locally,
clinopyroxene. The age of the northern phase is about 25 m.y ., based on interpretation of numerous discordant
K-Ar ages of both hornblende and biotite (Tabor and others, 1982, p. 8).

•

COMMENTS: This property is adjacent to the Apex property. Coats (1932, p. 17-19) describes the geology of the veins
in both mines. Because the mines were operated by the same company at the time of Coats' study, someproduction from the Damon may be included in Apex production figures.

TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.
ORE CONTROLS: Consists of three parallel, en echelon veins in granodiorite (Huntting, 1956, p. 57). Landes and others(1902, p. 86) report the ore vein has a maximum width of 181/2 ft. The presence of tourmaline and theproximity to an area of extensively explored porphyry copper mineralization (Clipper zone about 5 mi to
the southwest) suggest this may be similar mineralization.
GEOLOGIC SETTING: The Snoqualmie batholith, northern phase, consists of granodiorite and tonalite with biotite andhornblende: it is medium crystalline and mostly equigranular and has hypidiomorphic texture. It locallycontains clinopyroxene It is light-colored, coarsely jointed rock. The age of the northern phase is about 25
m.y., based on interpretation of numerous discordant K-Ar ages of both hornblende and biotite (Tabor andothers, 1982, p. 8).

PRODUCTION: Produced in 1908 (Huntting, 1956, p. 17).
TECTONIC SETTING: The Grand Central mine is located in a volcanic member of the Swauk Formation, which is
early Eocene (52 m.y.) and pre-Cascade arc magmatism (Tabor 1982, geol. map, p. 13).
ORE CONTROLS: Stibnite is present in the upper workings of the mine. Narrow veinlets of quartz, pyrite, and calcite
were observed on the lower level of the mine (Smith, 1915, p. 171, 185). These veinlets occur in a 40-ft-widezone in andesite (Livingston, 1971, p. 157).
GEOLOGIC SETTING: The mine is in andesite of the Silver Pass Volcanic member of the Swauk Formation (Taborand others, 1982, geol. map, p. 13). It is also at the contact between shales and andesite (Smith, 1913, p.
32-33).

PRODUCTION: Deposit has been extensively explored (Huntting, 1956, p. 196).
TECTONIC SETTING: The Snoqualmie batholith complex is part of early magmatism of the Cascade magmatic arc.
Mineralization probably occurred during emplacement of a later phase of the batholith.
ORE CONTROLS: Where granodiorite is in contact with limestone, the limestone is recrystallized to marble and partiallyreplaced by garnet and magnetite (Shedd and others, 1922, p. 90-92). A vein near the center of one of theclaims, reported to be 6 ft wide, contains abundant galena and sphalerite (Huntting, 1956, p. 196).
GEOLOGIC SETTINO: At the Guye mine, limestone and conglomerate of the Guye Sedimentary Member of the Naches
Formation (Frizzell and others, 1984, geol. map) was intruded by granodiorite of the Snoqualmie batholith(Shedd and others, 1922, p. 90-92).

PRODUCTION: One load of concentrates shipped to Tacoma in 1952. Also produced 1953-1955 (Huntting, 1956, p.
129). Concentrates shipped to smelter in 1942 (Livingston, 1971, p. 161). Reportedly produced 2,000 tonsof ore between 1951 and 1957 and a flotation mill was constructed on the property (Report of Mineral
Examination for 28 unpatented mineral claims of the Rainy property)
TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.
ORE CONTROLS: The property consists of two mineralized breccia pipes, called the east and west areas. The west
pipe is the area of the old Rainy mine, and the east pipe is located about 800 ft to the east (Grant, 1969,
p. 79-81). Grant also reports (p. 81) two rocks types are directly related to zones with proportionately higher
contents of sulfide minerals, biotite-quartz diorite replacement breccias, and a syenite-quartz monzonitegranite complex. He believes the replacement breccias are products of deuteric alteration and the syenite-quartzmonzonite-granite complex rocks occur as matrix material within breccia blocks. The following descriptionof the ore bodies is from Livingston (1971, p. 149, as obtained by personal commun. with A. R. Grant).
The east pipe's surface dimension is about 300 by 600 ft, and it consists of fragments of quartz diorite that
contain secondary biotite and a matrix of quartz and minor sulfide. The breccia is composed of angularfragments that range from a few inches to. several feet long. The sulfides are scattered in breccia fragments
and along fractures, and sulfides are generally finely divided in less mineralized parts of the pipe. Vugs
range up to 2 in. and are lined with quartz. Quartz is much less abundant in more sulfide-rich parts of thepipe. The west zone is a zone of shattering and contains quartz veins along west-trending fractures. Sulfides
are present in the quartz veins and as disseminations in the country rock.
GEOLOGIC SETTING: The Quartz Creek deposit is in rocks of the Snoqualmie batholith, northern phase, which consistsof granodiorite and tonalite and is light colored, medium crystalline, and mostly equigranular and has
hypidiomorphic texture. The rocks are coarsely jointed and contain biotite and hornblende and, locally,
clinopyroxene. The age of the northern phase is about 25 m.y ., based on interpretation of numerous discordant
K-Ar ages of both hornblende and biotite (Tabor and others, 1982, p. 8).
COMMENTS: An annual report for Inland Copper Ltd. reports the Quartz Creek property has an indicated reserve of
56,000 tons grading 5.5% Cu and 2.5 oz/ton Ag, or 905,000 tons of material averaging 1.1 % Cu.

PRODUCTION: The property produced about 20 flasks of mercury (Livingston, 1971, p. 154).
TECTONIC SETTING: The Eocene rocks were extensively folded and faulted prior to deposition of the cinnabar(Livingston, 1971, 153-154).
ORE CONTROLS: Two sets of faults cut the folded rocks; mineralization is present along both sets of faults. Cinnabarmineralization occurs in pods and disseminations in the fault breccia. Stibnite is common in the nearby
Cardinal Reward property (Rice, 1962, private report in DOER files).
GEOLOGIC SETTING: The Puget Group consists of predominantly fluvial and some nearshore marine sandstone,siltstone, claystone, and coal (Frizzell and others, 1984, p. 26). Much of the mineralization occurs at thecontact between sandstone and carbonaceous claystone (Rice, 1962, private report).

PRODUCTION: Produced in 1925 (Huntting, 1956, p. 59).
TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.
ORE CONTROLS: Gash veins are present in granodiorite. Some high-grade ore came from the No. 6 vein (Huntting,1956, p. 59).
GEOLOGIC SETTING: The Snoqualmie batholith, northern phase, is granodiorite and tonalite with biotite and hornblende.
It is medium crystalline, mostly equigranular, and hypidiomorphic. It locally contains clinopyroxene. It islight-colored, coarsely jointed rock. The age of the northern phase is about 25 m. y., based on interpretationof numerous discordant K-Ar ages of both hornblende and biotite (Tabor and others, 1982, p. 8).

PRODUCTION: Produced in 1908 (Huntting, 1956, p. 59).
TECTONIC SETTING: The Snoqualmie batholith is part of early magmatism of the Cascade magmatic arc.

•

ORE CONTROLS: A 20-ft body of tourmaline at the Una mine is described by Smith (1915, p. 184-185). The brief
description suggests the tourmaline is massive crystalline, but may also be a portion of a breccia pipe .
GEOLOGIC SETTING: The Una mine is in rocks of the Snoqualmie batholith, northern phase, which consists of
granodiorite and tonalite and is light colored, medium crystalline, and mostly equigranular and has
hypidiomorphic texture. The rocks are coarsely jointed and contain biotite and hornblende and, locally,
clinopyroxene. The age of the northern phase is about 25 m.y ., based on interpretation of numerous discordant
K-Ar ages of both hornblende and biotite (Tabor and others, 1982, p. 8).

PRODUCTION: 20 tons shipped to the Tacoma smelter prior to 1920 (Huntting, 1956, p. 60).
TECTONIC SETTING: Mineralization occurs in shear zones, along joint planes, and in a brecciated zone, which suggests
mineralization took place following deformation of metamorphic rocks and deposition of the overlying
Eocene rocks (Frizzell and others, 1984, geol. map; Huntting, 1956, p. 60).
ORE CONTROLS: Mineralization occurs in a narrow shear zone and in joint planes in a 20-40-ft-wide brecciated zone
in a granodiorite dike (Patty, 1921, p. 277), and a breccia zone as much as 500 ft wide between rhyoliteand basalt is mineralized (Huntting, 1956, p. 60).
GEOLOGIC SETTING: Host rocks for the deposit include a granodiorite dike probably related to the Snoqualmiebatholith (Patty, 1921, p. 277-278) and rhyolitic and basaltic rocks probably of the Naches Formation(Frizzell, and others, 1984, geol. map).

PRODUCTION: Produced 75 flasks of mercury in 1916, 489 flasks in 1926, 1,265 flasks 1926-1929, and 441 flasks in
1931 (Huntting, 1956, p. 265).
TECTONIC SETTING: Deltaic deposits of the Eocene Puget Group were folded and faulted during the Tertiary (Gard,
1968, p. 27-29). Mineralization probably took place during or shortly after deformation.

•

ORE CONTROLS: Cinnabar occurs in fractures and breccia along fault zones in sandstone, shale, and siltstone of the
Puget Group. Mafic rocks intruded the sediments, and all were subjected to folding and faulting prior tomineralization (Mackin, 1944, p. 8). The shear zone that localizes mineralization at the Barnum-McDonnell
deposit has a maximum thickness of 10 ft. The best ore is in tuffaceous sandstone (Huntting, 1956, p. 265).
GEOLOGIC SETTING: The sedimentary rocks of the Puget Group contain coal, and fossils suggest brackish water andestuarine depositional conditions (Mackin, 1944, p. 7).

PRODUCTION: Produced 100 tons in 1919; also produced in 1925 and 1928, but total production does not exceed 200
tons. An 18-ton shipment yielded 8.05% Cu and 0.09 oz/ton Au. Reported 1% to 5% Co in some samples(Huntting, 1956, p. 61).
TECTONIC SETTING: Rocks are part of the Cascade magmatic arc.

•

ORE CONTROLS: Mineralization occurs along joints or slip planes in granite. The ore zone ranges from 0.5 to 5 ft inwidth; the zone carries a streak of high-grade ore that is 1 to 14 in. wide. Gold values are associated withthe arsenopyrite. The ore from near the portal of an old drift about 15 ft above the present drift was slightly
radioactive (Huntting, 1956, p. 61).
GEOLOGIC SETTING: Mineralization occurs in granite (Huntting, 1956, p. 61) and would appear to be in dikes
emanating from the Tatoosh pluton (Schasse, 1987, p. 29).

TECTONIC SETTING: Cretaceous granitic rocks intrude rocks of the Kootenay arc and adjacent terranes in northeastern
Washington (Rhodes and Hyndman, 1988).
ORE CONTROLS: Quartz that is found in muscovite-rich pegmatite veins is of two types: (1) milky white quartz and(2) gray, massive quartz in segregations. Both types of quartz contain sparse flakes of molybdenite (Becraft
and Weis, 1963, p. 67-68). A cross fracture in the main vein contains lenses of black radioactive material(Huntting, 1956, p. 269).

PRODUCTION: Produced 5 tons of ore in 1915 containing 0.40 oz/ton Ag, 7.85% Cu, 3.2% Fe, and 65% insoluble(Huntting, 1956, p. 62).
TECTONIC SETTING: Host rocks of manganese deposits of the Olympic Peninsula formed at an ocean ridge or in aback arc basin at the active margin of the North American plate (Garrison, 1973; Snavely, 1987, p. 306-309).
ORE CONTROLS: Mineralization occurs along the contact between altered basalt and foliated sandstone-semischist(data from USGS MRDS, 1990; Tabor and Cady, 1978, geol. map). The deposit is in lenses that pinch andswell. Its maximum width is 8 ft, and the thickness is 50 ft. Lenticular bodies of manganese silicates occur
conformably along the eastward or upper contacts of the basalt members at elevations approaching 4,400
ft. A manganiferous lens at the collar of the shaft pinches and swells along strike and down dip. No red
limestone was exposed near the lens, but the limestone is found in the same stratigraphic horizon as themineralization a short distance to the northeast. Manganese minerals are largely buff, tan, and gray bementites;
also present are several thin veinlets. of neotocite (data from USGS MRDS, 1990).
GEOLOGIC SETTING: The principal country rocks in the area are altered basalts and argillite, graywacke, limestone,
and some phyllite. Near Kidney (Black and White) Lakes, they trend approximately N20E and dip steeply
eastward.

EocenePRODUCTION: A carload of ore produced during World War I ran 35% to 45% Mn and 17% to 30% Si0 2 (Huntting,1956, p. 261).
TECTONIC SETTING: Host rocks of manganese deposits of the Olympic Peninsula formed at an ocean ridge or in aback arc basin at the active margin of the North American plate (Garrison, 1973; Snavely, 1987, p. 306-309).
ORE CONTROLS: Lens-shaped ore body occurs in red limestone about 1 ft from its contact with basalt (data from
U.S.G.S. MRDS, 1990; Huntting, 1956, p. 261). Manganese mineralization consists of a tabular body ofbementite about 1.5 ft wide, 70 ft long, and 30 ft thick. Small amounts of secondary manganese oxides andjasper are associated with the bementite. Other small masses of manganese mineralization were found along
Copper Creek to the southwest (data from USGS MRDS, 1990). Manganese deposits of the region areassociated with spilites (Park, 1942, p. 311-312) and commonly are found with reddish pelagic limestoneinterbedded with the basalt. Manganese mineralization may be either disseminated in replacement bodies
OF volcanogenic exhalative/diagenetic bodies (Sorem and Gunn, 1967).

•

GEOLOGIC SETTING: The Crescent Formation, which hosts manganese mineralization on the Olympic Peninsula,· consists of Paleocene? and Eocene pillow basalts compositionally similar to ocean ridge basalts. Associatedpelagic limestones were deposited in deep water (Snavely, 1987, p. 306-308).

PRODUCTION: Production includes 6,831 tons shipped in 1939 that averaged 0.55 oz/ton Au, about 0.50 oz/ton Ag,
and 0.16% to 0.55% Cu (Huntting, 1956). Approximately 9,000 tons of ore were shipped in 1940 and 4,000
tons in 1942; 1,899 tons of concentrate were shipped in 1950 (Burnet, 1976). In 1951, 1,546 tons of copper
concentrate yielded 268,202 lb Cu, and 2,072 oz Au. Shipments were also made in 1952-1953 (Huntting,1956, p. 135).
TECTONIC SETTING: Newby Group rocks were probably deposited along or proximal to an island arc.
ORE CONTROLS: Sulfide deposits in the Alder mine are concordant with bedding in the host rocks and are strata-bound;hydrothermal alteration at the mine is also strata-bound. Sulfide minerals, including pyrite, sphalerite,
chalcopyrite, and galena, are found in veins. These veins are generally small, have no relation to the Alderstock that intrudes volcanic rocks near the mine, and have a random orientation (Burnet, 1976; Bunning,1990).
GEOLOGIC SETTING: Dacitic breccias of the Jurassic-Cretaceous Newby Group are host to volcanogenic massive
sulfide mineralization at the Alder mine. The Newby Group was intruded by the Alder Creek stock, which
has been dated at 137 ± 3.4 m.y. (Burnet, 1976; Bunning, 1990).
COMMENTS: The deposit was developed by three adits that total several hundred feet and a large open pit mine. A
300-ton/day flotation mill was built at the site (Huntting, 1956).

EocenePRODUCTION: Two 30-ton shipments of copper ore made in 1918-1919 (Moen, 1980, p. 69).
TECTONIC SETTING: East-west extension during the Eocene resulted in formation of the Toroda Creek graben andother structures in which a thick section of volcanic and sedimentary rocks was deposited and preserved(Holder and others, 1989).
ORE CONTROLS: The main mineralized structure is a 2-8-ft-wide silicified shear zone that strikes N45E and dips
50NW. Brecciated and sheared volcanic rock is cemented by quartz and sanidine and as much as 5% fluorite.
The silicified and fluoritized breccia body exposed on the surface above the adit is as much as 250 ft indiameter. The American Flag is the southernmost property of the Zalla M-Silver Bell mineralized belt thatis about 1 mi long and several hundred feet wide (Moen, 1980, p. 69).

•

GEOLOGIC SETTING: Volcanic rocks in this part of the Toroda Creek graben plot as rhyolite on a TAS diagram, butthey contain sparse plagioclase and mafic phenocrysts in an aphanitic groundmass that contains abundantplagioclase microlites. Plagioclase phenocrysts are commonly strongly sericitized, and mafic minerals are
generally replaced by some combination of chlorite, calcite, epidote, and sphene; shapes of altered mafic
minerals suggest that they were originally pyroxene. The presence of silica stringers and veinlets in someof these rocks suggests that silica was introduced during alteration (Stoffel, 1990, p. 11).
COMMENTS: The main adit is 97 ft long and trends N45E along a mineralized shear zone. Several small prospect pits
were present. Dump samples collected by Moen (1980, p. 69) contained a trace to 12.5 oz/ton Ag.

PRODUCTION: Produced a few hundred tons before 1910; had a small amount of production in 1940 (Huntting, 1956,
p. 135).

•TECTONIC SETTING: Magmatic arc rocks of the area include the Fawn Peale stock, which is probably the intrusive
equivalent of the volcanic member of the Midnight Peak Formation. The stock was probably the intrusive
rock core of an island arc (Riedell, 1979). The unit has yielded K-Ar magmatic biotite ages of approximately
88 m.y. (Stoffel, 1990, p. 28).
ORE CONTROLS: The deposit is in a breccia pipe. Strongly brecciated and partially rotated fragments of quartz diorite
as much as 3 cm long are in a matrix of quartz, tourmaline, calcite, pyrite, and chalcopyrite. The American
Flag deposit is part of the Mazama porphyry copper-molybdenum system (Riedell, 1979).
GEOLOGIC SETTING: The American Flag deposit is in a breccia pipe of the Fawn Peak stock of Cretaceous age. It
is an elongate, northwest-trending intrusion along the northeast side of the Methow River valley; it is situatedalong the axis of the Goat Peak syncline (Stoffel and McGroder, 1990).
COMMENTS: The American Flag deposit is part of the Mazama porphyry copper-molybdenum deposit (Riedell, 1979).

PRODUCTION: A test shipment was made prior to 1940 (Huntting, 1956, p. 300).

•

TECTONIC SETTING: The porphyritic granodiorite of Manila Creek is part of the Keller Butte suite of Holder andHolder (1988). Keller Butte suite rocks were emplaced contemporaneously with ductile deformation associatedwith the formation of the metamorphic core complexes (Holder and Holder, 1988) .
ORE CONTROLS: The deposit consists of fissure veins and breccia in granodiorite at and near its contact with quartzite
and limestone. The vein that contains the ore-rich horizon is in a cross shear that intersects the main vein,which strikes N68W and dips 40NE. Sulfide minerals are crudely zoned in the vein; pyrite is more abundantat the walls, and galena, sphalerite, and chalcopyrite are more abundant at the center of the vein. The hanging
wall has a gradational contact with the host rock, whereas the contact at the foot wall is sharp (Broch, 1979,
p. 139).
GEOLOGIC SETTING: The deposit is in the (Paleocene?)-Eocene- porphyritic granodiorite of Manila Creek (Gulick
and Korosec, 1990, geol. map).
COMMENTS: The main level crosscut intersects the main vein at approximately 150 ft. Two drifts were driven along
the vein (Broch, 1979).

PRODUCTION: A small amount of ore was extracted and may have been shipped in 1906. About 10 years later, 1,000
tons of stibnite ore and several hundred tons of antimony oxide, which had been manufactured in a small
plant near the mine, were shipped. About 2/3 of a carload of ore was shipped in 1941 (Purdy, 1951, p. 109).
TECTONIC SETTING: The Newby Group was deposited in an active margin setting, along or near an island arc.
ORE CONTROLS: The host rocks of the deposit strike N30-40W and dip 50-SOW. The dip of shear fractures containing
fine stringer veins is at a lower angle than that of the bedding. Alteration, while extensive, is limited to asmall area around the vein (Purdy, 1951 ).
GEOLOGIC SETTING: Mineralization is in veins in the graywacke and argillite of the Jurassic-Cretaceous Newby
Gr.oup (Bunning, 1990).
COMMENTS: The mine was developed by three main adits and about 1,000 ft of workings (Huntting, 1956 p. 18).

(Paleocene?)-Eocene

PRODUCTION: Estimated production from 1911 to 1940 was about $250,000 in Ag, and $20,000 in Au. Shipments to
the Tacoma smelter in 1911 contained about $350/ton Au and Ag. Small hand-sorted, high-grade shipments
contained as much as 2,444 oz/ton Ag. The bulk of the ore averaged 10-20 oz/ton Ag and was concentrated
at the Great Metals mill near Nespelem Falls prior to shipment to the smelter (Moen, 1976, p. 129).
TECTONIC SETTING: This epizonal pluton is part of the Keller Butte suite. Intrusion of the granodiorite was contemporaneous with deformation associated with the metamorphic core complexes (Holder and Holder, 1988).

•

ORE CONTROLS: The average strike of the vein is N45W, and the dip is northeast. Mineralization is a stockwork ofveins that are 0.2-1.2 in. wide; the ore zone at the Apache is 1.25 ft wide. The veins pinch and swell andhave sharp contacts with the host rock. Economic mineralization occurs as lenticular or tabular lenses andpods distributed along single veins. Ore shoots are complexly brecciated and contain angular fragments ofbroken wall rock and vein quartz. Open-space filling is exhibited by such features as euhedral quartz crystals.
A wide alteration halo surrounds the veins at the surface (Broch, 1979).
GEOLOGIC SETTING: The veins are in a shear zone in the (Paleocene?)-Eocene porphyritic granodiorite of Manila
Creek.
COMMENTS: The vein was accessed by several adits (Broch, 1979).

PRODUCTION: The Arlington vein was one of the first deposits to be discovered on Ruby Hill. One thousand tons ofsilver ore, which had a net value of $25,000, were mined by the summer of 1893 and concentrated at a millin Ruby City. Between 1914 and 1921, several thousand tons of ore which contained 66.6 oz/ton Ag weremined at a net profit of $31,000. A 50-ton/day flotation mill was erected in 1937. Between 1938 and 1939,
5,700 tons of ore that had a net value of $71,683 were concentrated in the mill. Mining and milling operations
ceased early in 1940 (Moen, 1973, p. 12).
TECTONIC SETTING: The Conconully pluton is a directionless, post-tectonic plutonic rock that was intruded into amajor structural zone (Stoffel, K. L., DOER, 1990, oral commun.).
ORE CONTROLS: The Arlington vein is 1-6 ft thick, strikes north, and dips 70W. The vein for the most part occurs
along the contact between the Conconully pluton and gneiss. Transverse faults offset the vein as much as
10 ft, whereas faults that parallel the vein have drawn the ore minerals out into thin dark-gray bands (Moen,
1973, p. 12).
GEOLOGIC SETTING: The Arlington vein occurs in the Conconully pluton of Cretaceous age near the contact withgneiss of the metamorphic complex of Conconully (Moen, 1973; Rinehart, 1981; Stoffel, 1990).

COMMENTS: Underground workings consisted of shafts, drifts, and crosscuts that have a total length of 4,500 ft. The
workings exposed the vein on four levels for a total vertical distance of 540 ft (Moen, 1973, p. 12).

PRODUCTION: Mining in 1951-52 yielded an estimated 100 tons of ore (Huntting, 1956, p. 18).
TECTONIC SETTING: The metasedimentary rocks were originally deposits in an active margin environment; theinterleaving of metaperidotite with supracrustal rocks suggests that significant tectonic mixing predated thecomplicated folding and metamorphic history of the Twisp Valley Schist (Bunning, 1990).
ORE CONTROLS: The mineralized zone consists of three elements: intensely hydrothermally altered wall rock, quartz,
and lenticular masses of stibnite. The altered rock that encloses the veinlets and irregular masses of stibnite
is composed of erratically distributed, alternating iron-oxide stained and bleached rock that is composed ofquartz, sericite, and minor amounts of kaolin. Crisscrossing the altered rock are veinlets and microveinlets
of stibiconite. The contact between the wall rock and the lenticular masses of stibnite is characterized by
the presence of quartz, especially drusy quartz in the vugs. The vein or mineralized zone strikes about N47E
and dips 80SE. The zone containing stibnite ranges from several inches to 5 ft in width (Purdy, 1951, p.
122-123).
GEOLOGIC SETTING: The mineralized system is within hornblende-quartz diorite of the Twisp Valley Schist (Purdy,
1951; Bunning, 1990, geol. map).

PRODUCTION: High-grade copper ore was shipped from one of the shafts in 1918 (Moen, 1980, p.57).
TECTONIC SETTING: Deposit is in an alkalic intrusive complex.
ORE CONTROLS: Mineralization is contained in several undulating shear zones in hydrothermally altered alaskite,
aplite, and monzonite (Purdy, 1954, p. 34-44). Shear zones do not appear to continue for more than 30 ft.
Sericite, kaolinite, and disseminated ore minerals are present in the shear zones. Ore minerals are localized
in small ore shoots.
GEOLOGIC SETTING: The deposit is within the alkalic complex of Bimetallic Mountain, which is of Cretaceous or
Tertiary age. The monzonite, which is brecciated and locally includes shonkinite, is intruded by hydrothermally altered, fine-grained, alaskite dikes. The rocks intrude metasedimentary rocks of the Spectacle Formation of the Permian Anarchist Group, which are locally hornfelsed (Stoffel, 1990).
COMMENTS: Development consists of several shafts and two adits. A total of 2,200 ft of linear trenching was doneby the U.S. Bureau of Mines (USBM) in 1945 to determine the extent of mineralization; no significant
mineralization was found. Assays of samples from the adit by the USBM ranged from 2.20 to 3.87% Mo
and 0.03 to 0.32% Cu and showed traces of Au and Ag. Samples taken from the trench averaged 0.32%
Cu; trace amounts of Au and Ag were found in some samples. Sampling suggests that the better copper
values are found in samples from near the surface, whereas the higher molybdenum values are from samples
collected at deeper levels in the mineralized system (Moen, 1980, p. 57).

PRODUCTION: About 5,000 tons of ore were taken out in 1901 (Huntting, 1956, p. 63).
TECTONIC SETTING: The Blue Goat pluton is a elongate pluton that is roughly concordant with the regional foliationin the local metamorphic rocks, but contacts are locally sharp and discordant. The country rock was probably
deformed and metamorphosed prior to the emplacement of the pluton (Rinehart and Fox, 1976, p. 32).

EocenePRODUCTION: A 10-stamp amalgamation-cyanide mill processed approximately 15,000 tons of gold ore from 1902 to
1916. In 1930 a 70-ton/day mill was built to recover free gold and low-grade ore that contained about 0.65
oz/ton Au and 0.60 oz/ton Ag. In 1938, the capacity of the mill was increased to 125 tons/day, and cyanidationand flotation circuits were added. Mining and milling were carried out until 1944, with as many as 40 miners
working three shifts and producing as much as $1,500 of Au and Ag a day. From 1930 to 1944, about
50,000 tons of ore valued at about $280,000 was mined.
TECTONIC SETTING: These rocks were deposited in the Toroda Creek graben, a volcano-tectonic depression that was
the result of east-west extension in the Eocene (Holder and others, 1989).
ORE CONTROLS: The Bodie vein is 2-22 ft wide and consists of many, parallel, closely spaced quartz veins. The
individual veins are several inches to 5 ft in width and strike north to N16E and dip 60-80W. Vein quartz
is white to light gray, fine grained, and commonly chalcedonic and colloform. Prospects pits have exposed
the vein for about 6,000 ft; underground workings indicate the vein extends in excess of 500 ft along its
dip. Gold is rarely visible; sulfides and magnetite are fine grained and disseminated in the quartz. The black
streaks that parallel the walls contain dustlike particles of sulfides and gold and are the richest part of thevein. The gold grade in protore diminishes with depth from about 0.15 to 0.002 oz/ton; ore from the surface
to the 100 level averaged about 1 oz/ton Au. The silver to gold ratio is 1: 1. In addition to the veins, gold
occurs in breccia in volcanic rocks that adjoin the Bodie vein on the west. The breccia strikes north anddips 35-45W. In the upper workings of the mine the breccia forms the hanging wall of the vein. The breccia
extends below the 700 level to an undetermined depth. Clasts of the breccia are highly to moderately alteredvolcanic rocks and are cemented by crypotocrystalline silica and gouge (Moen, 1980, p. 73).
GEOLOGIC SETTING: The deposit is in the Klondike Mountain Formation. Whole-rock geochemistry suggests thatthe rock is a rhyolite; however, thin section work by Stoffel (1990) suggests that altered mafic minerals
were originally pyroxenes and that the high silica content of the rock may be due to the addition of silica
in the form of stringers and veinlets.
COMMENTS: Most of the mining took place on the Bodie No. 1 claim. At least 10,000 ft of underground work on fivemain crosscut adits penetrate the breccia and intersect the vein. A glory hole mined rich parts of the Bodie
vein at the surface (Moen, 1980, p. 74).

PRODUCTION: Between 1908 and 1916, the mine was operated by British Columbia Copper Co., and eight carloadsof gold-silver-copper ore were shipped to smelters in British Columbia (Moen, 1980, p. 43).
TECTONIC SETTING: The Spectacle Formation was deposited along an active continental margin.
ORE CONTROLS: Contact metamorphic deposit at the contact of metasedimentary rocks and biotite-homblende granodiorite (Moen, 1980, p. 43).
GEOLOGIC SETTING: The contact metamorphic deposit is found at the contact of Permian metasedimentary rocks andthe Jurassic-Cretaceous granodiorite of the Buckhorn Mountain pluton (Moen, 1980, p. 43; Stoffel, 1990,
p.29).

•COMMENTS: This deposit appears to be a northwesterly extension of the ore bodies at the Magnetic mine. Shafts,
adits, prospect pits, and trenches are on the property. A core hole drilled by Granby Consolidated Mining,
Smelting & Power Co. contained intercepts of 0.2-4.3% Cu within 112 ft of the surface.

TECTONIC SETTING: Eocene volcano-tectonic depressions formed as the result of regional east-west extension (Holder
and others, 1989) .
ORE CONTROLS: According to Moen (1973), the deposit is in brecciated and silicifed black argillite that has been
intruded by an north-trending aplite porphyry dike, which appears to be several hundred feet wide. Parts ofthe dike contain pods of galena and pyrite that are accompanied by minor chalcopyrite and sphalerite (Moen,
1973, p. 37). Rinehart and Fox (1976) indicate the deposit is in a Tertiary crystal tuff intruded by a Tertiarydike.
GEOLOGIC SETTING: According to Rinehart and Fox (1976) and Stoffel (1990), the deposit is within crystal-lithic
and crystal tuff of Eocene age intruded by a northwest-trending dacitic dike.
COMMENTS: A shaft has been sunk 50 ft on the dike, and drifts were driven at 32 and 50 ft below the collar of the
shaft (Moen, 1973, p. 37).

PRODUCTION: Two tons of hand-sorted ore were shipped in 1914 (Huntting, 1956, p. 63).
TECTONIC SETTING: The andesite of Isabella Ridge was deposited in an island arc setting during the Cretaceous.
ORE CONTROLS: A fracture zone in andesite 80-100 ft wide contains locally distributed copper and a minor amountsof gold and silver (Huntting, 1956, p. 63). Mineralization occurs in many small shears in shattered andesitic
pyroclastic rocks that are cut by several plagioclase porphyry dikes.
GEOLOGIC SETTING: The deposit is in andesite of Isabella Ridge, which is of probable Cretaceous age (Stoffel andMcGroder, 1990).
COMMENTS: The property was developed by a 200-ft adit, a 50-ft adit, and several open cuts (Huntting, 1956, p. 63).

MINERALlZATION AGE

massive sulfide
PRODUCTION: Produced an unknown amount of ore prior to 1911. Produced 3,486 tons of ore in 1918-1919, which
averaged 3.147% Cu, 0.42 oz/ton Ag, and 0.03 oz/ton Au (Huntting, 1956, p. 64).
TECTONIC SETTING: Rocks of the Palmer Mountain Greenstone were probably deposited proximal to island arcs.
ORE CONTROLS: The mineralized zone trends N85W, dips 40SW, and contains massive sulfides in en echelon podsin schistose andesite. Hanging wall andesite is highly silicified. A fault is probably present between themineralization and the silicified andesite; talc and serpentine developed between the mineralized zones. The
andesite is altered, and thin sections show that plagioclase and augite are extensively replaced by secondary
epidote, calcite, quartz, and chlorite (Patty, 1921, p. 242-243; Rinehart and Fox, 1972, p. 84).
GEOLOGIC SETTING: Ore is in en echelon tabular lenses in altered andesite of the Permian-Triassic Palmer MountainGreenstone (Patty, 1921, p. 241; Rinehart and Fox, 1972, p. 84).
COMMENTS: A 300-ft shaft was driven; crosscuts are on the 100-, 200-, and 300-ft levels (Rinehart and Fox, 1972).

PRODUCTION: A mill was built in 1908, but there is no record that the mill produced concentrate. A small-scale mining
operation was carried out from 1937 to 1941; this resulted in several carloads of ore being shipped to thesmelter in Trail, British Columbia, and to the Bunker Hill smelter in Idaho. A few shipments ran as highas 1 oz/ton Au, 33 oz/ton Ag, and 28% Pb. The mine has been idle since 1941 (Moen, 1980, p. 44-45).
TECTONIC SETTING: Late Paleozoic rocks were deposited along an active continental margin.
ORE CONTROLS: Quartz fissure veins are in limestone, argillite, and quartzite and in quartz- and plagioclase-bearing
porphyritic rocks. The Nl5-80E-striking vein dips 10-35NW and is 8-12 in. wide. Gouge zones are present
along the hanging and foot walls of the vein; normal faults perpendicular to the vein have resulted in minor
offsets. Sulfide minerals are sparsely disseminated in the vein or are present as thin, discontinuous bands
that roughly parallel the walls of the vein (Moen, 1980, p. 45).
GEOLOGIC SETTING: Metasedimentary rocks of the Permian Spectacle Formation were intruded by quartz-plagioclase
porphyritic intrusive rock of Mesozoic age (Moen, 1980, p. 45).

COMMENTS: Several adits were driven into the south-facing hillside at the property. The property is on patented mining
claims (Moen, 1980, p. 44).

PRODUCTION: The mine produced silver ore valued at $66,000 from 1892 to 1893. Production came to an end during
the silver panic of 1893. Several small shipments of silver ore were made from the mine in the 1920s (Moen,
1973, p. 16).
TECTONIC SETTING: The Conconully pluton is a directionless, post-tectonic plutonic rock that intruded into a major
structural zone (Stoffel, K. L., DOER, 1990, oral commun.).

•ORE CONTROLS: Mineralization occurs in discontinuous lenticular lenses of quartz that are as much as 90 ft thick
and as much as 700 ft in maximum width. The lenses strike NlOE and dip 55 to 60E. They are present inhighly foliated micaceous gneiss and feldspathic quartzite in the metamorphic complex of Conconully. The
trend of the lenses of quartz is parallel to the foliation in the gneiss. Ore minerals are concentrated in ore
shoots along the walls of the lenses; some of the ore shoots are as much as 5 ft thick. The ore shoots contain75-100 oz/ton Ag, whereas the massive quartz between the shoots contains only 6-8 oz/ton Ag (Moen, 1973,
p. 16-17).
GEOLOGIC SETTING: The mineralization at the First Thought occurs in the gneiss and quartzite of the metamorphic
complex of Conconully near the contact of the Conconully pluton of Cretaceous (Rinehart, 1981; Stoffel,
1990).
COMMENTS: Underground workings of the First Thought mine consist of more than 4,000 ft of drifts on three levels
that have a vertical extent of 350 ft (Moen, 1973, p. 17).

PRODUCTION: Produced 20 or more carloads of high-grade ore and concentrates between 1918 and 1921; 600 tons
were milled in 1939 (Huntting, 1956, p.219).
TECTONIC SETTING: The sediments and volcanic materials of the Kobau Formation were deposited proximal to an
island arc along a convergent continental margin.
ORE CONTROLS: A vein striking N7W and dipping 32-37W is in granodiorite at its contact with a roof pendant (Patty,
1921, p. 233; Rinehart and Fox, 1972).
GEOLOGIC SETTING: The deposit is a vein in the Similkameen composite pluton at or near the contact with quartzite(chert), limestone, and greenstone (hornblende schist) of the Kobau Formation of Permian or Triassic (?)
age.

vein
PRODUCTION: The vein was discovered in 1887. In 1889 a shipment of high-grade silver, ore was sent to the smelterin Helena, Montana. A 200 ft shaft was sunk on the vein, and an average of 10 tons of high-grade ore permonth was shipped to smelters. Silver ore was shipped to a concentrating mill in Ruby City until mid-1893
when the mine was forced to shut down because of the silver panic. Total production to this time amounted
to $36,000. From 1958 to 1964 hand-sorted shipments were sent to the smelter in Trail, British Columbia.
Except for a small shipment in 1967, those were the last shipments from the mine (Moen, 1973).
TECTONIC SETTING: The Salmon Creek schist and gneiss is laterally equivalent to the metamorphic complex of
Conconully (Gulick and Korosec, 1990), which is thought by Rinehart and Fox (1976) to grade into andinclude Late Triassic rocks. Late Triassic sedimentary rocks were deposited in an active continental margin
setting associated with an island arc.

•

ORE CONTROLS: The vein, which averages 6 ft in thickness, strikes NlOW and dips 70-80E. The vein is in biotite
gneiss and is parallel to the contact with a granodiorite gneiss that is several hundred feet to the west. The
ore minerals seem to be in a 2-ft-thick band that parallels the hanging wall. Parts of the vein are sheared;
shears parallel the vein (Moen, 1973, p. 13-14). ·GEOLOGIC SETTING: The vein is in biotite gneiss of the pre-Jurassic Salmon Creek schist and gneiss parallel to andwest of the contact with granodiorite gneiss (Moen, 1973).
COMMENTS: The underground workings at the mine consist of a double-compartment 500-ft shaft and a single-compartment 200-ft shaft. Several levels have been driven and mined (Moen, 1973).

PRODUCTION: Reportedly, 1,000 tons of ore was shipped prior to 1943; 1,250 tons were shipped in 1943 (Huntting,1956, p. 198).
TECTONIC SETTING: Migmatitic parts of the gneiss of Alta Lake; migmatization appears to have been a polyphase
event that involved both anatexis and igneous injection (Gulick and Korosec, 1990).
ORE CONTROLS: Magnetite is intimately intermixed with large amounts of hornblende and actinolite. The ore is coarse
grained and has a schistose appearance. Ore occurs in seams and thin lenses. The deposit varies from a few
feet to 15 ft thick and is exposed along strike for 400-500 ft. The mineralized zone grades into the gneiss
and migmatite (Shedd and others, 1922).
GEOLOGIC SETTING: The Fuller deposit is in the migmatitic part of the amphibolite, schist, and gneiss of the Alta
Lake migmatite. The migmatite is gradational with the layered metamorphic rocks and is characterized byirregular, lenticular, swirled, and contorted granitic, tonalitic, aplitic, and pegmatitic leucosomes (Gulick
and Korosec, 1990, p. 40).

PRODUCTION: Sporadic production of copper and gold from 1910 to 1934; total production probably did not exceed
5,000 tons (Moen, 1980, p. 47). Handy (1916, p. 8) reports that six carloads of ore containing $10-$20 per
ton in Au and minor amounts of silver were shipped. Huntting (1956, p. 139) reports 16 or 17 carloads ofore were shipped in 1914-15.
TECTONIC SETTING: The Kobau Formation was deposited along an active continental margin proximal to an island
arc.
ORE CONTROLS: The shear zone trends N34W and dips from 65SW to vertical; magnetite and pyrrhotite occur inlens-like bodies with garnet and epidote along the shear zone and range from several inches to 1 ft in width.
The contact metamorphic zone is not as well developed here as at the Magnetic mine (Moen, 1980, p. 47).
GEOLOGIC SETTING: The Jurassic-Cretaceous Buckhorn Mountain pluton intruded and contact metamorphosed limestones and greenstones of the Permian or Triassic (?) Kobau Formation.
COMMENTS: Development of the property consists of an adit and many prospect pits. Drilled by Crown Resources
Corp. in 1989 and by Battle Mountain Gold in 1990. The property is part of a joint venture between Crown
Resources and Battle Mountain Gold and is known as the Buckhorn Mountain deposit.

PRODUCTION: In 1931, 37 tons of ore were shipped (Huntting, 1956, p. 140).

•

TECTONIC SETTING: The Midnight Peak Formation and the Fawn Peak stock were part of a Cretaceous island arc(Riedell, 1979).
ORE CONTROLS: The ore consists of quartz stringer veins that are mineralized to some extent (Huntting, 1956, p.
140). The deposit is in the actinolite-chlorite zone of the Mazama molybdenum porphyry system. Veins
peripheral to the porphyry system generally trend N10-40E and N70-85W (Riedell, 1979).
GEOLOGIC SETTING: The Gold Key mine is in andesites of the Midnight Peak Formation, which are intruded by theCretaceous Fawn Peak stock. The stock is probably the intrusive equivalent of the volcanic rocks (Stoffel
and McGroder, 1990, p. 15).

PRODUCTION: Produced $4,000 worth of ore prior to 1911; nine carloads of hand-sorted ore shipped sometime later(Huntting, 1956, p. 65).
TECTONIC SETTING: The Kobau Formation was deposited along an active continental margin proximal to an island~-.

ORE CONTROLS: The 5-ft-wide ore zone strikes north and dips 35W; it consists of a series of S-shaped mineralized
quartz lenses. The quartz lenses range from a fraction of an inch to a foot in thickness (Culver and Broughton,
1945, p. 32-33). The deposit contains stockwork with quartz-K-feldspar flooding and sericitic alteration
which is part of the Kelsey copper-molybdenum porphyry copper system (Roper, 1973).
GEOLOGIC SETTING: The deposit is in argillite of the Permian or Triassic (?) Kobau Formation and quartz diorite
and fine-grained diorite of the concentrically zoned Jurassic-Cretaceous (?) Silver Nail Lake pluton (Stoffel,
1990; p. 28).

•

COMMENTS: The property was opened up by an inclined shaft down the 30 degree dip of the ore zone for a reported
distance of 350 ft; several open cuts were also present (Culver and Broughton, 1945 , p. 32).

PRODUCTION: Small-scale mining in late 1900s. Minor production in 1916, 1921-24, 1937-39, and 1950-51; value
probably less than $50,000. Most mining was by pick and shovel. A small amalgamation mill was built in
1950-51; only 8 tons of ore containing a total of 4 oz Au and 4 oz Ag were mined and milled (Moen, 1980,
p. 35).

•TECTONIC SETTING: The Kobau Formation was deposited along an active continental margin proximal to an island
arc.
ORE CONTROLS: North-striking, west-dipping, quartz and calcite veins in fractures 0.5-6 in. wide in sheared andbrecciated rock. Visible gold is present in veins and stringers. The adit is in hydrothermally altered granitic
rocks, greenstone, and siltite (Moen, 1980, p. 35).
GEOLOGIC SETTING: The vein is in siltite and greenstone of the Kobau Formation; altered granitic rocks occur withthe mineralization.
COMMENTS: Mining on the Gray Eagle claim appears to have been carried out on two widely separated veins. Oneof the veins has also been mined as part of the Reco vein in the No. 2 adit of the Reco mine.

PRODUCTION: Several carloads were shipped prior to and during 1909 (Huntting, 1956, p.304); the values were mostly
in silver and the ore averaged $62/ton in 1909 (Rinehart and Fox, 1972, p. 90).
TECTONIC SETTING: Rocks of the Palmer Mountain Greenstone were deposited along an active continental margin
proximal to an island arc.
ORE CONTROLS: Three veins are present on the property. The most developed vein strikes N53E and dips 40NW, andis from 4 in. to 4 ft wide, averaging 18 in. (Rinehart and Fox, 1972, p. 90).
GEOLOGIC SETTING: The quartz vein is in metavolcanic rocks of the Palmer Mountain Greenstone (Rinehart andFox, 1972, geol. map).
COMMENTS: Development consists of a 75-ft adit and a 100-ft shaft (Moen, 1976, p. 122).

PRODUCTION: Produced an unknown amount of ore in 1940 and 1942 (Huntting, 1956, p. 142).
TECTONIC SETTING: The Methow Gneiss protolith was probably intruded at moderate crustal levels; the intrusive
was later metamorphosed to the amphibolite grade together with other metamorphic rocks in the area
(Bunning, 1990).
ORE CONTROLS: Mineralization is in a 3-ft-wide quartz vein in gneissic diorite (Huntting, 1956, p. 142).
GEOLOGIC SETTING: The deposit consists of a vein in the Methow Gneiss (Bunning, 1990, geol. map).

PRODUCTION: Hand-sorted, near-surface ores mined between 1888 and 1897 contained as much as 1,000 oz/ton Ag
and several ounces of Au. Approximately 1,000 tons of ore was shipped to smelters in Washington andMontana; several shipments averaged 392 oz/ton Ag and 1.2 oz/ton Au (Moen, 1976, p. 123; Rinehart andFox, 1972, p. 91).
TECTONIC SETTING: Sediments of the Anarchist Group were deposited along an active continental margin.
ORE CONTROLS: Seven quartz veins were mined. The Ivanhoe vein is 3.5-4.5 ft thick and strikes north-northwest anddips 60W. Silver ore was richer near the surface; veins intersected at a depth of 1,560 ft had average Ag
content of less than 1 oz/ton (Umpleby, 1911).
GEOLOGIC SETTING: The vein is in phyllite and argillite of the Permian Bullfrog Mountain Formation of the Anarchist
Group.
COMMENTS: The Ivanhoe vein was developed by several shallow shafts, one of which was later sunk to a depth of
500 ft. The richest ores were near the surface; these were mined by stripping the hanging wall of the veinover an area 70 by 120 ft. In about 1914, a 4,400-ft crosscut was driven from the west slope of Palmer
Mountain in an attempt to intersect the vein at a depth of 1,560 ft (Umpleby, 1911).

PRODUCTION: Produced 5.9 tons of ore in 1955; these assayed 42% Cr20 3 and had a Cr/Fe ratio of 2.9 (Huntting,1956, p. 38).
TECTONIC SETTING: An ultramafic mass in the North Cascades .
ORE CONTROLS: The deposit is near an ultrabasic-dolomite contact. Chromite is disseminated sparsely through theultrabasic rock. Near the ultrabasic-dolomite contact, a tabular body of nearly solid chromite is present; itmeasures 7.5 ft by 6 ft by 3 ft. A stringer about 2 in. wide and 18 in. long was found about 10 ft north ofthe main pod (Huntting, 1956, p. 38).
GEOLOGIC SETTING: The deposit is in calc-silicate rock derived from altered ultrabasic rocks or from dolomitic
sedimentary rocks. The chromite-bearing unit consists of calc-silicate minerals and magnesite, talc, andtremolite; serpentinized magnesite talc schist; and gamet-diopside calc-silicate granofels, hornblende schist,and serpentinized carbonate (Gulick and Korosec, 1990, p. 27).

PRODUCTION: Produced in 1918 and 1943-1951; total is about 205,000 oz of Ag. From 1943 to 1946, the mine
produced 135,973 oz Ag, 1,357,185 lb Pb, 506,050 lb Zn, and 99,410 lb Cu (Moen, 1976, p. 123).
TECTONIC SETTING: The Similkameen batholith is a concentrically zoned plutonic suite with early mafic alkalic rocks
bordering and being intruded by calc-alkalic granitic rocks. The undeformed body is on the upper plate of
the Okanogan Valley fault (Buddington and Burmester, 1990).
ORE CONTROLS: The vein at the Kaaba mine is a persistent, but low-grade, banded quartz vein that strikes N3W, dips
43-55W, and averages 10 ft in width. This vein appears to be bordered by two dikes; however, at the 200-ft
level the dike in the footwall cuts the vein, and 50 ft below the collar, the veinis entirely in the Similkameencomposite pluton (Patty, 1921, p. 230). Patty (1921) suggests that the dikes are younger than the mineralization
because they are not altered and because they cut mineralized rock. The depth to the bottom of the deposit
is 240 ft.
GEOLOGIC SETTING: The vein is in the granodiorite of the Similkameen composite pluton of Jurassic age.
COMMENTS: An inclined shaft is 300 ft long with 1,100 ft of drifts are on four levels; more than half the drifting ison the third level. A 150-ton/day flotation mill was constructed on property (Huntting, 1956, p. 220).

TECTONIC SETTING: The porphyritic granodiorite of Manila Creek is part of the Keller Butte suite of Holder andHolder (1988). Intrusion of Keller Butte suite rocks into metasedimentary country rocks was contemporaneouswith regional ductile stretching associated with the formation of the metamorphic core complexes (Holder
and Holder, 1988).
ORE CONTROLS: Weak mineralization is present along fractures in granite and quartzite. One quartz vein is 2-in. wide
(Huntting, 1956, p. 66).

PRODUCTION: Has not produced.
TECTONIC SETTING: To the north in British Columbia, distribution of major porphyry copper deposits is, in part,
controlled by the Quesnel trough. The Kelsey property lies on the southward projection of this structural
trough and is similar to mined deposits to the north.
ORE CONTROLS: The bulk of the mineralization is in the Silver Nail pluton, a coarsely crystalline quartz diorite. The
intrusive is sheeted; contacts between the various phases are fairly flat. Sills and thrust faults are present.
At the south end of the property, the pluton is brecciated. Permian Anarchist Group rocks (slate, phyllite,
impure marble, greenstone, metaconglomerate, and metawacke) were incorporated as fragments in the breccia
and as slivers in the pluton. The most concentrated copper-molybdenum mineralization is associated withquartz-sericire alteration and intense fracturing; country rock surrounding the mineralized zone is chloritized.
Mineralization in greenstone and limy portions of the Anarchist Group consists of copper-bearing tactite
containing pyrrhotite, minor garnet. and epidote. Quartz veins contain chalcopyrite-rich pods. Huntting(1956, p. 67) reports 18 assays averaging 2.62% Cu, 0.6 oz/ton Ag, and 0.04 oz/ton Au. During the 1960s,
exploration programs for porphyry copper deposits outlined two zones in the pluton. The Central Zone is
4,800 ft long, has a northwest-trending axis, and averages 1,530 ft wide. It contains 66,575,200 tons of
indicated ore averaging 0.286% Cu and an additional 137,560,000 tons of inferred ore of similar grade. The
geological potential of the central zone to a depth of 600 ft is 280,000,000 tons. Molybdenum credits arevariable and range from 0.015 to 0.02% MoS . Hole K-3 drilled by Inland Copper Ltd. encountered 85 ft
of ore averaging 0.407% Cu and 0.13% Mo. i:he Northwest Zone contains a total of 34,320,000 tons of
indicated and inferred ore grading 0.241 % Cu. The Northwest Zone extends across the international boundary
into British Columbia.
GEOLOGIC SETTING: The major rock type at the Kelsey deposit is the Jurassic-Cretaceous (?) Silver Nail quartz
diorite pluton. Subordinate intrusive rock types are quartz monzonite and syenite. Late aplite occurs near
the south contact. All intrude Permian Anarchist Group greenstone, phyllite, slate, and minor marble,
limestone, and quartzite. Tertiary conglomerate and dacite adjoining the deposit are not altered, and therefore,are post ore.
COMMENTS: The Kelsey property, in 1974, consisted of 15 patented claims, 91 unpatented claims, and land held infee. It was discovered in the late 1800s, and attempts were made to develop the higher grade quartz veins.
From 1965 to 1974 American Smelting and Refining Co., Inland Copper Ltd., Canadian Superior Exploration
Ltd., St. Joe Minerals Corp., Placer-Amex Inc., and U.S. Borax explored the property for porphyry copper
deposits. They drilled a total of 36,085 ft of X-ray, rotary, percussion, and core holes. The property in now(1990) owned by Wilbur G. Hallauer of Oroville.

PRODUCTION: Produced a total of 1,500 tons; 12 tons were produced in 1914 and netted $444 in Ag and Pb (Moen,
1973, p. 28).
TECTONIC SETTING: Triassic (or pre-Jurassic) sediments were deposited along an active continental margin setting .
ORE CONTROLS: The sparsely metallized quartz vein is 3-10 ft thick, strikes N25E, and dips 60NW.
GEOLOGIC SETTING: The vein is in schist and migmatite of the metamorphic complex of Conconully. These rocks
are thought by Rinehart and Fox (1976) to be in part Late Triassic because they are intruded by a small
pluton that is correlated with the Loomis pluton, dated at 194 m.y.
COMMENTS: Development at the property consists of a 300-ft adit, a 80-ft shaft, and a 105-ft drift (Moen, 1973, p.
28).

TECTONIC SETTING: Marine rocks of the Spectacle Formation were derived from sediments deposited along an active
continental margin.
ORE CONTROLS: Mineralization is present in en echelon lenses of quartz as much as 50 ft in long and 1-5 ft wide,in the hanging wall over contact (possibly fault) that strikes N46W and dips 52SW between a porphyritic

PRODUCTION: Ore was blocked out but was not mined because of the silver panic of 1983. In 1920 the mine wasreopened, and ore that averaged 30 oz/ton Ag, 17% Pb, and 4% Cu was shipped to a smelter at Bradley,
Idaho. Small shipments of ore were made again in 1921 and 1924 (Moen, 1973, p. 18).
TECTONIC SETTING: The quartz monzonite was probably emplaced in a magmatic arc.
ORE CONTROLS: The quartz fissure vein that averages 12 ft in width strikes S50E and dips 70SW. Ore minerals areconcentrated in ore shoots that are 2-4 ft thick and as much as 200 ft long. Ore minerals are sparsely
disseminated between ore shoots (Moen, 1973, p. 18).
GEOLOGIC SETTING: The vein is in granodiorite of Cretaceous age near the contact with homblende-biotite schist of
the metamorphic complex of Conconully (Gulick and Korosec, 1990, geol. map).

vein
PRODUCTION: By 1890, ore that contained as much as 200 oz/ton Ag and 30% Pb was mined from several levels. By
1897, about $40,000 had been spent developing the mine, but production amounted to only several thousand
dollars. Trial shipments of ore were made to smelters in 1913, 1943, and 1969 (Moen, 1973, p. 25) .
TECTONIC SETTING: The quartz monzonite was probably emplaced in a magmatic arc.
ORE CONTROLS: The main vein has an average thickness of 3 ft, strikes north, and dips 45-50W. On the south endof the vein, where shearing and faulting in the granodiorite is prominent, the vein consists of as much as
12 ft of banded quartz. The south end of the vein has been offset as much as 50 ft by faults. Ore minerals
are generally sparsely scattered through the vein. However, in some parts of the vein, the ore minerals areconcentrated in bands as much as several feet wide, which parallel the walls of the vein (Moen, 1973, p.
26).

•

GEOLOGIC SETTING: The vein is in the medium- to coarse-grained granodiorite and quartz monzonite of the Conconully
pluton. The pluton is hydrothermally altered on its eastern edge near the town of Conconully (Stoffel, 1990
p. 24).
COMMENTS: The Lone Star mine has more than 2,000 ft of underground workings in the form of shafts, drifts, andcrosscuts (Moen, 1973, p. 26).

PRODUCTION: About 40 tons assaying 62% Sb were shipped in about 1907. A plant to transform stibnite to antimony
oxide was built at the site between 1915 and 1917. Antimony oxide and about 500 tons of high-grade stibnite
ore were shipped. One carload containing 42 tons of hand-sorted ore grading 30.47% Sb was shipped in
1941. In 1948, seven shipments totaling 47 tons of hand-sorted material that averaged 55.9% Sb were made(Purdy, 1951, p. 94-96).

•

TECTONIC SETTING: Sediments of the Spectacle Formation were deposited along an active continental margin .
ORE CONTROLS: Stibnite crystals are found in veinlets in fractured and generally silicified limestone beds and in
faults in the limestone beds overlying phyllitic beds. Stibnite sometimes is present along bedding planes inlimestone, and in some places, the stibnite replaces the limestone (Purdy, 1951, p. 99-101).
GEOLOGIC SETTING: The deposit is in a sequence limestone and phyllite of the Permian Spectacle Formation of theAnarchist Group (Stoffel, 1990, geol. map).

COMMENTS: Development consists of 1,000 ft of drifts, crosscuts, and winzes (Huntting, 1956, p. 19).

PRODUCTION: Small shipments of copper ore were made from the Neutral claim to a smelter in British Columbia. A
total of 80,000 tons of magnetite were shipped from the Neutral claim between 1918 and 1950 (Moen, 1980,
p. 47).
TECTONIC SETTING: Late Paleozoic sediments were deposited along an active continental margin.

•

ORE CONTROLS: Contact-metamorphic replacement of limestone in contact with the Cretaceous or Jurassic Buckhorn
Mountain pluton. The magnetite zone is proximal to the pluton; tactite includes grossularite garnet, epidote,
zoisite, quartz, and calcite. Tactite pods in places contain disseminated grains, pods, and pockets of intermixed
magnetite, pyrrhotite, pyrite and chalcopyrite. Magnetite is irregularly distributed in the tactite zone, butnear the Magnetic mine, it is roughly parallel to the northeast-trending contact, which appears to dip about
65SW (Moen, 1980, p. 47-49). Shear zones contain moderate amounts of sulfides and an estimated several
million tons of iron ore (Huntting, 1956, p. 199).
GEOLOGIC SETTING: Magnetite bodies are located in a northwest-trending contact-metamorphic zone in limestonesof Permian age adjacent to biotite-hornblende granodiorite of the Jurassic-Cretaceous Buckhorn Mountainpluton (Moen, 1980, p. 47; Stoffel, 1990).
COMMENTS: Development work consisted of three open pits, two adits, and numerous open cuts and prospects pits.
The main pit is 280 ft long and 65-130 ft wide and has a maximum vertical face of 50 ft (Moen, 1980, p.
49). The Magnetite mine is part of the Buckhorn Mountain project drilled by Crown Resources Corp. in
1988-89. Other than iron the ore bodies contain traces to 0.02% Cu, traces to 0.15 oz/ton Au, and 0.05-0.40
oz/ton Ag (Moen, 1980, p. 49). Broughton (1943, p.17) estimated reserves of 4,826,000 tons of iron ore
averaging 47.3% Fe, 1.57% S, 0.03% P, and 0.03% Ti.

PRODUCTION: There is no recorded production.
TECTONIC SETTING: The Fawn Peak stock was probably the intrusive rock core of an island arc (Riedell, 1979) .
ORE CONTROLS: Mineralization is confined to fractures and a breccia body. This appears to be primarily a porphyry
copper deposit that has no other metal values. Reserves are given as nearly 150 million tons averaging
0.36% Cu. The overall waste to ore ratio is 2.5:1. Quartz veins 0.5 mi to the south at the Mazama Pridemine produced 37 tons of ore in 1931, which contained copper and 0.7 oz/ton Au.
GEOLOGIC SETTING: The Fawn Peak stock is an elongate, northwest-trending intrusion along the northeast side of
the Methow River valley; it is situated along the axis of the Goat Peak syncline. The stock consists of finely
to coarsely crystalline diorite, porphyritic quartz diorite, plagioclase porphyry, and intrusion breccia. The
porphyritic rocks occur along the border of the stock. The stock intrudes the Winthrop Sandstone and theMidnight Peak Formation. The sandstone contains epidote (homfels) alteration. Swarms of porphyritic sills
and dikes extend as much as 1 km from the stock. The intrusive breccia is a pipelike body and consists ofsubrounded clasts as much as 10 in. long of diorite, quartz diorite, andesite, and andesite porphyry in amatrix of plagioclase porphyry. Three K-Ar mag_matic biotite ages for the stock averaged 88 m.y. Alteredrocks in the stock yield K-Ar secondary biotite ages of 85.1 ± 3.5 m.y. and 69.7 ± 2.9 m.y.

COMMENTS: This property consists of unpatented mining claims and is being explored (1990) by Vanderbilt Gold
Corporation. Considerable drilling was conducted by Bear Creek, Noranda, Inspiration Development Co.,
and Quintana. Bear Creek and Inspiration spent $700,000 on drilling.

PRODUCTION: $40,000 in gold was produced in 1940-41 (Huntting, 1956, p. 144).
TECTONIC SETTING: The Methow Gneiss is a Cretaceous intrusive body that has been metamorphosed to amphibolite
grade (Bunning, 1990).
ORE CONTROLS: The deposit is made up of several veins. The New London vein is less than 1 ft wide and contains
quartz, pyrite, gold, chalcopyrite, and scheelite. It lies along the footwall of a narrow basic dike that strikes
N60E and dips 55NW. Scheelite crystals are disseminated in the quartz veins and are as much as 0.5 in.
across. The veins are cut by several reverse faults. Other veins on the property are similarly mineralized
and either parallel basic dikes or are contained within them (Culver and Broughton, 1945, p. 48-49).
GEOLOGIC SETTING: These veins are in basic dikes of probably Eocene age and which cut the Cretaceous Methow
Gneiss (Bunning, 1990; Culver and Broughton, 1945).
COMMENTS: The quartz veins that make up the deposit were developed by several shafts and adits. More than 2,200ft of underground workings were present; more than half of these were west of the Methow River (Huntting,1956, p. 144).

EocenePRODUCTION: Ten tons of ore in 1939 and 22 tons in 1940 were shipped to the Tacoma smelter (Huntting, 1956, p.
144).
TECTONIC SETTING: The Golden Hom batholith was intruded into the Hozameen fault, the major fault bounding thesouthwestern side of the Methow basin. Radiometric dating suggests that magmatic crystallization occurred
at approximately 47 m.y. K-Ar biotite, fission-track allanite, and Rb-Sr isochron ages that fall between 38
and 42 m.y. probably represent the age of postcrystallization hydrothermal alteration (Stoffel and McGroder,1990).
ORE CONTROLS: The deposit consists of two mineralized quartz veins in granite (Huntting, 1956, p. 144).
GEOLOGIC SETTING: The veins are in granite of the Golden Horn batholith of Eocene age (Stoffel and McGroder,1990).

PRODUCTION: Shipped one carload of ore in 1941. A carload of ore shipped in November 1945 netted $667.56 andgave assays of 0.46 oz/ton Au and 7.75 oz/ton Ag. A mining and gold heap-leach operation was worked by
Cordilleran Exploration, Inc., in 1984-85 (Huntting, 1956, p.144; Joseph, 1986) .
TECTONIC SETTING: Much of the rock of the Leecher Metamorphics has been recrystallized after mylonitization,
probably due to the intrusion of the Okanogan complex (Bunning, 1990, p. 40).
ORE CONTROLS: The vein at the Minnie mine strikes N15E, dips 63SE, and parallels the orientation of the fabric in
the Leecher Metamorphics. The porous white quartz vein averages 3 ft in width (Culver and Broughton,
1945, p. 52-53; Bunning, 1990, p. 28).
GEOLOGIC SETTING: The vein is parallel to the fabric in the biotite schist and marble in the Leecher Metamorphics.
The deposit is reported to be within 1,000 ft of the Summit-Frazer gneiss of Cretaceous age (Culver andBroughton, 1945, p. 52-3; Bunning, 1990).
COMMENTS: The property was mined in 1984 and 1985 by Cordilleran Exploration, Inc. A small heap-leach system
was operated by the company; dore was poured on site (Joseph, 1986).

PRODUCTION: The mine was worked as early as 1890, but mining ceased during the silver panic of 1893. Between
1951 and 1954, ore that contained as much as 60 oz/ton Ag was produced. In 1961 and 1967, small shipmentsof silver ore were made to the Cominco smelter in Trail, British Columbia (Moen, 1973).
TECTONIC .SETTING: The Conconully pluton is a directionless post-tectonic body that was intruded into a major
structural zone (Stoffel, K. L., DOER, oral commun., 1990).
ORE CONTROLS: The 1.5-3-ft-wide vein has a general strike ofN30W and dips 30-40SW. Ore minerals are concentrated
in bands as much as 1 ft wide that contain as much as 60 oz/ton Ag, 13% Pb, and 3% Cu (Moen, 1973, p.
24).
GEOLOGIC SETTING: The vein is in the biotite- and hornblende-bearing Conconully pluton of Cretaceous age (Stoffel,
1990).

•COMMENTS: Two adits were worked at the property (Moen, 1973, p.24).

PRODUCTION: Small shipments were made in 1922, 1931, 1934, and 1935 (Huntting, 1956, p. 144). One shipment of
3,639 lb made in 1934 assayed 4.1 % Cu, 2.08 oz/ton Au, and 1.9 oz/ton Ag (Staatz and others, 1971).
Another shipment of crude ore yielded 1.81 % Cu, 1.53 oz/ton Au, 1.13 oz/ton Ag, and a minor amount ofbismuth (Huntting, 1956, p. 144). The Mountain Beaver is the only claim in the Billy Goat property to haveproduced (Staatz and others, 1971).
TECTONIC SETTING: The volcanics were deposited as part of an island arc.

•

ORE CONTROLS: Andesite tuff and breccia generally strike N30W and dip 70W to vertical. A plagioclase porphyry
dike or sill is discontinuously exposed along the west edge of the Billy Goat property. Pyrite and copper
minerals occur locally in 0.25-2-in.-wide quartz veinlets, which are located near steeply dipping, northwesttrending faults and fractures. The veinlets are disseminated through the fractured and layered andesite andthe plagioclase porphyry (Staatz and other, 1971, p.111-112).
GEOLOGIC SETTING: Mineralization is present in andesite tuff and breccia of probable Cretaceous age and in aplagioclase porphyry dike or sill that intrudes the volcanic rocks (Staatz, 1990).
COMMENTS: The property was reportedly developed by two adits (Staatz and others, 1971).

Rocks of the Keller Butte suite were emplaced during regional ductile stretching associated with deformationin the metamorphic core complexes (Holder and Holder, 1988).
ORE CONTROLS: Rocks near the Mountain Boy mine trend northeast and dip 30-60NW. Quartz lenses at the minevary from 0.5 to 18 in. in width and from 2 in. to 30 ft in length. The lenses contain irregularly scatteredpatches of sulfide minerals. The sulfide minerals show some banding and are brecciated. Both the quartz
lenses and the metasedimentary rocks are cut by calcite-filled stringers (Pardee, 1918, p. 95).
GEOLOGIC SETTING: Veins are in metasedimentary rocks of probable Paleozoic age that are intruded by the nearby
Paleocene-Eocene granite of Moses Mountain (Joseph, 1990).
COMMENTS: Three adits with short drifts, inclines, and other workings are located near each other at the Mountain
Boy (Pardee, 1918)

PRODUCTION: A few cars of ore were shipped prior to 1911 (Huntting, 1956, p. 307).
TECTONIC SETTING: The Kobau Formation was deposited along an active continental margin proximal to an island
arc.
ORE CONTROLS: The deposit is on same fault as and is similar to the Ruby deposit. The vein trends N65W, dips
35SW, and can be traced for 3,000 ft along the outcrop. The vein is altered as much as 4 ft from the fault(Huntting, 1956, p. 307; Rinehart and Fox, 1972, p. 96).
GEOLOGIC SETTING: The Kobau Formation is intruded by granodiorite and tonalite of the Triassic-Jurassic Loomis
pluton. Mineralization is present in a west-northwest trending-fault near the contact (Rinehart and Fox,
1972, geol. map).
COMMENTS: Three adits totaling 2,000 ft were driven (Rinehart and Fox, 1972).

PRODUCTION: In 1901 a carload of ore was shipped to a smelter; $10/ton was received. In 1923-24 several small
shipments of lead and copper ore were made; however, returns from the smelter did not exceed mining
costs. In 1957 ore was concentrated at a flotation mill in Omak and shipped to the smelter (Moen, 1973, p.
20).
TECTONIC SETTING: Late Triassic rocks of the area formed in an active margin setting. The Conconully pluton is adirectionless, post-tectonic pluton that was intruded into a major structural zone (Stoffel, K. L., DOER,
1990, oral commun.)•

ORE CONTROLS: The 3-5-ft-thick vein has a general strike of N15W and dips 60E. The Nevada vein is the most
persistent of several metallized quartz veins on Peacock Mountain. It is in hornblende-biotite schist andquartz diorite gneiss and parallels the foliation in the metamorphic rocks. Ore minerals are disseminated in
the veins or concentrated in bands as much as 1 ft thick that parallel the walls of the vein. The silver ispresent mainly in galena. Tetrahedrite occurs near the surface. At 100 ft beneath the surface chalcopyrite
1s the dominant copper mineral (Moen, 1976, p. 20).
GEOLOGIC SETTING: The deposit is in hornblende- and biotite-bearing schist and quartz diorite gneiss near the contact
with the Conconully pluton of Cretaceous age, according to Moen (1973). The deposit is shown as being
within the metamorphic complex of Conconully by Stoffel (1990) and is shown by Rinehart to be (1981)
at the contact of the Conconully pluton of Cretaceous age and metasedimentary and metavolcanic rocks ofPermian and Triassic age that are elsewhere (Rinehart and Fox, 1976) shown as the metamorphic complex
of Conconully.
COMMENTS: Underground workings at the Nevada mine consisted of four shafts, the deepest which is 220 ft, several
hundred feet of drifts, and a 1,000-ft adit (Moen, 1973).

PRODUCTION: The mine has produced, but the amount is unknown (Huntting, 1956, p. 221).

•

TECTONIC SETTING: The Similkameen batholith is a concentrically zoned plutonic body with early mafic alkalic
rocks bordering and intruded by calc-alkalic granitic rocks. The complex is undeformed and on the upper
plate of the Okanogan valley fault (Buddington and Burmester, 1990) .
ORE CONTROLS: Irregular mineralized bodies of friable quartz, which are commonly mixed with gouge, occur along
the margins of a brecciated zone in the granodiorite. The principal ore has been mined from near the hanging
wall; the contact with the granodiorite on the hanging wall is sharp, but it is gradational on the footwall.
The brecciated zone is as much as 100 ft wide at one place (Umpleby, 1911, p. 90).
GEOLOGIC SETTING: In the Jurassic Similkameen composite pluton (Rinehart and Fox, 1972, geol. map).
COMMENTS: The deposit was developed by a 1,700 ft adit (Rinehart and Fox, 1972).

PRODUCTION: Three carloads of ore were shipped prior to 1911. Nineteen carloads of ore were shipped between 1917
and 1921; this ore averaged 7% Cu, 6 oz/ton Ag, and $2/ton Au. Approximately 1,000-2,000 tons of 1-2%
Cu ore remains on the dump and in the workings (Patty, 1921, p. 244).
TECTONIC SETTING: The Silver Nail Lake pluton was probably emplaced in a magmatic arc.
ORE CONTROLS: The deposit is in the silicifed-sericitic zone of the Kelsey porphyry copper deposit (Roper, 1973).
Mineralization is in a shear zone striking NlOW and dipping 30-50 southwest. The quartz diorite is crumpled
along the shear zone and consists of light-green quartz-mica and serpentine schist over a width of 6-10 ft.
Pinch and swells have formed along which mineralization has developed; mineralization also cements broken
wall rock and replaces schist along planes of schistosity (Patty, 1921, p. 245).
GEOLOGIC SETTING: Mineralization is in a shear zone in quartz diorite of the Jurassic-Cretaceous (?) Silver Nail
Lake pluton (Fox, 1970).
COMMENTS: Part of the Kelsey porphyry copper-molybdenum deposit (Roper, 1973).

PRODUCTION: A 12-ton shipment of hand-sorted ore was made to the Tacoma smelter; it returned 56.8 oz/ton Ag and9.32 oz/ton Au (Colville Confederated Tribes, 1984). Shipments totaling 26 tons were made in 1919, 1921,
and 1936 (Moen, 1976).

•

TECTONIC SETTING: The porphyritic granodiorite of Manila Creek is part of the Keller Butte suite of Holder andHolder (1988). Rocks of the Keller Butte suite were emplaced during regional ductile stretching that resulted
in the deformation associated with the metamorphic core complexes (Holer and Holder, 1988) .
ORE CONTROLS: Quartz lenses and veins are present in a 4-ft-wide shear zone in the granodiorite (Moen, 1976). The
vein may be crosscut by an Eocene hypabyassal dacite dike (Colville Confederated Tribes, 1984).
GEOLOGIC SETTING: The veins are in the (Paleocene?)-Eocene porphyritic granodiorite of Manila Creek (Gulick andKorosec, 1990, geol. map).

PRODUCTION: The Poland China was discovered in 1896. A 25-ton/day mill was erected in 1907 which produced asmall shipment in 1914. Overtop Mining Co shipped 168 tons of concentrate containing 72 oz of Au and70 oz of Ag in 1933-1934. From 1937 to 1939, 11 carloads of siliceous ore assaying 0.37 oz/ton Au wereshipped to the smelter in Trail, British Columbia. Mining ceased in 1939 (Moen, 1980, p.35-37) .
TECTONIC SETTING: Marine sedimentary rocks of the Spectacle Formation formed along an active continental margin.
ORE CONTROLS: The deposit contains a black to white, northwest-striking, east-dipping, 2-15-ft-wide quartz vein ingraphitic argillite. The vein walls are generally well-defined, but in several places the vein gradually grades
into the argillite; the vein also contains fragments of argillite. Locally, the vein is offset by north- andnortheast-trending, high-angle faults. Ore minerals are sparsely disseminated in quartz (Moen, 1980, P. 37).
GEOLOGIC SETTING: The vein is in graphitic argillite of the Permian Spectacle Formation of the Anarchist Group(Moen, 1980).
COMMENTS: High-grade near-surface ore contained 0.15-30 oz/ton Au. Ore that was mined averaged only 0.24 oz/ton
Au and 0.40 oz/ton Ag. Some wall rock contained from 0.018 to 0.06 oz/ton Au. Development consistedof more than 1,500 ft of adits, shafts, and crosscuts. This property is on patented mining claims (Moen,
1980, p. 38).

PRODUCTION: Most of work at mine took place between 1897 and 1900. From 1916 to 1953, the mine produced 1,015
tons of ore valued at $23,000 from gold and $365 from silver. The mine has been idle since 1953 (Moen,
1980, p. 40).
TECTONIC SETTING: Sedimentary and volcanic materials of the Kobau Formation were deposited proximal to an
island arc along a convergent continental margin.
ORE CONTROLS: The 1-2-ft-wide vein strikes north and dips 50-70W. The vein consists of quartz and minor calcite
and is sheared and fractured due to recurrent movement. Ore minerals are sparse and are present as disseminated grains, small blebs, and thin, dark bands in the quartz. Native gold was present in high-grade ore
mined near the surface but absent in deeper parts of the vein. About 30 ft from the surface, the vein terminatedat a north-dipping fault. Most of the vein is on the Gray Eagle claim. Gold content ranges from 0.04 to 16.8
oz/ton. Ore averaged 0.87 oz/ton Au, and most of it was hand sorted (Moen, 1980, p. 40).

•GEOLOGIC SETTING: A north-striking vein in the Kobau Formation, which was intruded by Mesozoic intermediate
and acidic composition dikes (Stoffel, 1990).
COMMENTS: Development work consists of several prospect pits, trenches, short adits, and two main adits. The longest
adit (No. 2) was driven for 148 ft onto the Gray Eagle claim. The property is on patented mining claims(Moen, 1980, p. 40).

PRODUCTION: Twelve carloads of hand-sorted ore were shipped to smelters in 1911; ore ran 7-9% Cu, 0.10-0.20
oz/ton Au, and 3.75-7.5 oz/ton Ag (Huntting, 1956, p. 199). In 1919-20 a total of 2,000 tons of iron ore
was shipped (Moen, 1980, p. 54).
TECTONIC SETTING: The Spectacle Formation was deposited along an active continental margin.
ORE CONTROLS: Ore minerals occur at the contact between Permian metasedimentary rocks and the biotite-hornblendeof the Jurassic-Cretaceous Buckhorn Mountain pluton. The contact metamorphic zone contains hornfels andcalc-silicate rocks and minor quartzite, marble, and phyllite. The skam and the ore bodies occur as irregularreplacements that apparently favored beds of limestone and calcareous shale. Ore minerals are present as
disseminated grains, as well as in pods and lenses. Small, sparsely disseminated grains of scheelite occur
in gamet-epidote-rich areas of the contact zone.
GEOLOGIC SETTING: Contact metamorphic deposit at the contact of Permian metasedimentary rocks and the JurassicCretaceous, biotite-hornblende Buckhorn Mountain pluton (Moen, 1980, p. 54; Stoffel, 1990).
COMMENTS: The main development at the Roosevelt mine consisted of an 855-ft lower adit with about 750 ft of drifts
and crosscuts. About 200 ft higher in elevation are several open cuts and caved adits. The upper adits appear
to be the earlier workings. The lower adit was driven in an attempt to intersect the downward extension of
the ore bodies. However, these bodies apparently did not extend to the depth of the lower adit, althoughisolated occurrences of magnetite were found (Moen, 1980, p. 54). Broughton (1943, p. 20-21) estimatedonly about 2,000 tons of magnetite remains in the floor of the large stope of the lower adit. He also reported
an area of moderately high dip needle readings S60E, 250 ft from the stope.

PRODUCTION: The mine produced approximately 100,000 oz Ag from 1915 to 1922. High-grade ore contained asmuch as several hundred oz/ton Ag, but mill-run ore averaged only 10 oz/ton Ag. A mill (capacity 75-ton/day)
was built in 1920. Prior to 1920, crude ore was shipped to smelters.
TECTONIC SETTING: The quartz monzonite was probably emplaced in a magmatic arc.
ORE CONTROLS: The quartz fissure vein is in a shear zone in granodiorite; the zone strikes N45W and dips 42SW.
Ore minerals occur as sparsely scattered grains in the vein (Moen, 1976, p. 121).
GEOLOGIC SETTING: The vein is in a shear zone in granodiorite of Jurassic-Cretaceous (?) age (Rinehart and Fox,
1972).

•COMMENTS: The mine was developed by at least 5,000 ft of underground workings and several stopes. The main adit
intersects the vein at 950 ft from the portal and 550 ft beneath the outcrop. A 75-ton/day mill was built atth~ site in 1920 (Moen, 1976, p. 121).

EocenePRODUCTION: Between 1906 and 1919, shipments of high-grade gold-silver ore were made to smelters. In 1918 a
50-ton/day flotation mill was built at the mine, and concentrates averaging as much as 300 oz/ton Ag wereshipped until 1920. For this period, the mine production was estimated at $60,000 to $100,000 (Moen, 1980,
p. 72).
TECTONIC SETTING: The Toroda Creek graben is a volcano-tectonic depression, which resulted from east-west
extension during the Eocene (Holder and others, 1989).
ORE CONTROLS: Silver minerals occur in a series of closely spaced, silicified and pyritized shear zones in alteredand silicified andesites and dacites. Brecciation of the rocks accompanied the shearing, and clasts of the
breccia have been considerably altered and silicified by hydrothermal solutions. The main vein is 1-7 ft
wide, strikes N20E, and dips 50NW. During mining operations it was necessary to closely assay the veinmaterial in order to establish borders of the ore shoots (Moen, 1980, p. 72).
GEOLOGIC SETTING: The ore is in altered and silicified volcanic rocks of the Eocene Klondike Mountain Formation.
The geology here is similar to that described for the American Flag mine).
COMMENTS: A 50-ton/day flotation mill was built in 1918. Most adits have heading of N35E. The vein was minedfrom several levels over a vertical distance of about 500 ft and along strike for about 400 ft. Several raises
connect the different levels of the mine (Moen, 1980, p. 72).

EocenePRODUCTION: High-grade gold ore was reported shipl'ed from a surface pit prior to 1907. In 1940 a 29-ton shipment
gave net smelter returns of $244.03 (Hunttmg, 1956, p. 148). There was a small amount of production in
the 1980s.
TECTONIC SETTING: East-west extension during the Eocene resulted in formation of the Toroda Creek graben andother structures in which a thick section of volcanic and sedimentary materials was deposited and preserved(Holder and others, 1989).
ORE CONTROLS: The deposit is contained in brecciated and silicified trachyte. The breccia has a general northeast
strike and dips about 45W. The breccia is about 50-75 ft wide and is cemented with quartz, sanidine, andas much as 4% fluorite. The deposit is near the center of the Zalla M-American Flag mineralized belt, whichis almost a mile long and several hundred feet wide (Moen, 1980, p. 69).
GEOLOGIC SETTING: Geologic setting is similar to that at the American Flag mine where volcanic rocks in this partof the Toroda Creek graben plot as rhyolite on a T AS diagram, but contain sparse plagioclase and mafic
phenocrysts in an aphanitic groundmass that contains abundant plagioclase micro lites. Plagioclase phenocrysts
are commonly strongly sericitized, and mafic minerals are generally replaced by some combination ofchlorite, calcite, epidote, and sphene; shapes of altered mafic minerals suggest that they were originallypyroxene. The presence of silica stringers and veinlets in some of these rocks suggests that silica wasintroduced during alteration (Stoffel, 1990, p. 11).

•

COMMENTS: Underground workings consist of two adits, a 50-ft shaft, and several shallow shafts. Moen (1980, p. 70)
reported that drilling done by the owner of the property in 1978 delineated 124,000 tons of rock having an
average value of 5.46 oz/ton Ag and 0.014 oz/ton Au. Moen (1980, p. 69) also reported assays on thesiliceous breccia that range from 0-30 oz/ton Ag; as much as 120 ft of breccia assayed 3.0 oz/ton Ag and,a 13-ft section assayed as much as 26.55 oz/ton Ag.

PRODUCTION: One carload of ore was said to have been shipped (Huntting, 1956, p. 310).
TECTONIC SETTING: The porphyritic granodiorite of Manila Creek is part of the Keller Butte suite of Holder andHolder (1988). The Keller Butte suite is contemporaneous with the formation of the metamorphic corecomplexes (Holder and Holder, 1988).
ORE CONTROLS: Mineralization is present as disseminated grains of chalcopyrite, pyrite, and galena in metasedimentaryrocks and in veins that cut the metasedimentary rocks and granodiorite. Several veins at the property range
in thickness from several inches to 3 ft, strike N70W to N70E, and dip to the south (Pardee, 1918, p. 75-76).
Hydrothermal alteration extends for several feet on either side of the veins (Colville Confederated Tribes,
1984, p. 53). Altered granodiorite near one open cut contains as much as 30 ft of rock that is sericitizedand partially replaced by quartz and contains disseminated grains of pyrite, galena, and chalcopyrite (Pardee,
1918, p. 76).

PRODUCTION: Small amounts of ore were shipped in 1939 and 1954. Six tons shipped in 1941 contained 0.40 oz/ton
Au, 20.25 oz/ton Ag, 4.5% Zn, and 3.8% Pb (Huntting, 1956, p. 149; Burnet, 1976, table 2).
TECTONIC SETTING: The Newby Group was deposited at or near volcanic island arcs.
ORE CONTROLS: An irregular quartz-calcite vein in dacite ranges from a few inches to 3 ft thick. Ore minerals arein bunches in the vein (Huntting, 1956, p. 149). The host rock is silicified dacite breccia. Some mineralizationis also in a fault zone at the contact with the Alder stock and in quartz-sericite phyllite that is on strikewith the Alder mine (Burnet, 1976).

•

GEOLOGIC SETTING: MineraHzation is in silicified dacite breccia of the Jurassic-Cretaceous Newby Group; in places
the Newby Group is contact metamorphosed by the Alder Creek stock, which was dated at 137 ± 4 m.y.
(Burnet, 1976; Bunning, 1990).

PRODUCTION: Three thousand tons of hand-sorted ore, which averaged 1.0% MoS 2, was shipped in 1939 (Huntting,1956, p. 271). Material from dumps of the No. 1 and No. 2 adits was shipped after 1944.

•

TECTONIC SETTING: In British Columbia to the north, the Quesnel trough partly controls the distribution of major
porphyry copper-molybdenum deposits. The Starr molybdenum property lies on the projection of this structural trough.
ORE CONTROLS: The deposit is an elliptical body striking northwest and is as much as 130 ft wide and 300-440 ft
long. Mineralization is disseminated in silicified granodiorite, in fractures, associated with breccia, and inquartz veins. The deposit is oxidized to a depth of 30 ft with half of the molybdenum values molybdenite.
Sampling in the No. 1 adit, which is entirely within the mineralized zone, gave a weighted average of 0.51 %Mo~ 2• Samples from a winze from the No. 2 adit returned assays of 0.81-1.91 % MoS 2. Arsenic assays by
the USGS for ten samples ranged from 0.01 to 0.04%. On the basis of trench and underground sampling,
indicated and inferred reserves to a depth of 300 ft total 800,000 tons averaging 0.30% MoS 2. The deposit
is open at depth. There is a potential for 2 million tons averaging 0.26% MoS 2 (Wilbur Hallauer, personalcommun., Aug. 15, 1967).
GEOLOGIC SETTING: The northwest-trending Aeneas Creek pluton is 1 mi wide and 3 mi long. It consists of a central
phase and a border phase that is in contact with Permian Anarchist Group metasedimentary rocks. The
deposit is in the central phase of the pluton. The pluton consists of medium crystalline biotite-homblendequartz monzonite and granodiorite. The pluton has yielded K-Ar biotite ages of 92.7 ± 6.6 m.y. and 98.3 ±3.6 m.y. A concordant K-Ar hornblende age was 92.3 ± 4.3 m.y.
COMMENTS: The property consists of unpatented mining claims and is owned (1990) by Wilbur G. Hallauer of Oroville.
In 1928 the property was explored by Molybdenum Corporation of America and in 1935 and 1936 byTitanium Alloy Manufacturing Co. Carl Lundstrom mined the property in 1939. In total there are 2,700 feetof underground workings. In 1959 six short diamond drill holes were completed. From 1966 to 1967 Cambri
Mining and Development Co. Ltd. leased the property and drilled six 200-ft holes.

PRODUCTION: Reportedly, 60 carloads of ore were produced prior to 1897; the total was valued at $72,000. Seven
tons of ore that were shipped in 1940 assayed 0.63 oz/ton Au, 0.80 oz/ton Ag, and 0.17% Cu. Ore was also
shipped in 1941 (Huntting, 1956, p. 149).
TECTONIC SETTING: The Methow Gneiss is a post-tectonic body that was originally intruded at moderate to deeplevels and then metamorphosed to amphibolite-facies grade rock (Gulick and Korosec, 1990, p, 38).
ORE CONTROLS: The deposit consists of shear zones as much as 6 ft wide but averaging less than 3 ft. The shear
zones are in granite along the margins of "andesite" dikes. The shear zones also contain small, scatteredpods of shipping-grade ore (Huntting, 1956, p. 149). The andesite dikes noted in Huntting (1956) are probably
dacite dikes (Gulick and Korosec, 1990, geol. map).
GEOLOGIC SETTING: The Methow Gneiss of Cretaceous age is sheared and intruded by hypabyssal dikes of probable
Eocene age near the deposit (Gulick and Korosec, 1990, geol. map).
COMMENTS: The deposit may also be part of the Friday mine. The Sullivan mine was developed by 1,200 ft of workings
on three levels (Huntting, 1956).

PRODUCTION: Concentrates recovered from 85 tons of ore in 1937 were worth $1,538; total production in 1937 wasabout $1,900 (Huntting, 1956, p. 149).
TECTONIC SETTING:The Palmer Mountain Greenstone was deposited along a convergent continental margin proximal
to an island arc.
ORE CONTROLS: The deposit consists of a 1.5-6-ft-wide, nearly vertical vein trending N55W in aphanitic greenstone
and medium-grained metagabbro. Chlorite alteration is present near the vein (Rinehart and Fox, 1972, p.
78).
GEOLOGIC SETTING: The vein is in greenstone and metagabbro of the Permian-Triassic Palmer Mountain Greenstone(Rinehart and Fox, 1972).
COMMENTS: The deposit was developed by three shafts totaling 420 ft and five adits totaling 1,200 ft (Huntting, 1956,
p. 149).
