Area traversed by major thrust fault. Veins, veinlets, and pipes of
fluorite-beryllium rock in jointed and faulted limestone and dolomite are
localized along this and a lower (suspected but not exposed) thrust. Min-
eralized rock at surface is mainly fluorite, diaspore, tourmaline, white
mica, and chrysoberyl with small amounts of other beryllium minerals. At
depths of several hundred feet drill holes encountered sulfide minerals
(including galena and sphalerite) and cassiterite. Deposits grade east-
ward into nearly barren fine-grained silica. Granite stock or cupola may
underlie area at depth greater than 500 ft. Traces of cassiterite in
churn-drill holes in stream gravels. See also: Alaska Chief, (Lost R.).

Graphite occurs as massive lenses several inches thick and as disseminated

material in intensely altered quartz and garnet schists near a major fault.
Lenses of high-grade material make up about 50% of rock in material exposed
by 50 ft of trenches. Samples of high-grade material ran 59.73% graphite,

80% of which was coarser than 30 mesh. Some of the 100 tons mined by Alas-—

SUPPLEMENT TO OPEN-FILE REPORT 75-587

PART A -- SUMMARIES OF DATA TO JANUARY 1, 1980

By
Edward H. Cobb

Open-file Report 81-3644
1981

This report is preliminary and has
not been reviewed for conformity

with U.S. Geological Survey editorial
standards.


Gold mining had begun by 1900. Bedrock is chlorite, mica, and graphitic
schists, limestone, slate, and greenstone sills; many quartz veins. Some
of gold very coarse. Some very rich pockets on bedrock (up to $50 per
yd3; gold at $20.67). Both creek and bench placers; at least one old
channel in one bench was mined. Concentrates contained cinnaber, plat-
inum-group metals, and scheelite. Dredge operated from confluence that
forms Bluestone R. upstream to above mouth of Alder Cr. (about 4 mi) from
1935 to at least as recently as 1940. Other kinds of mining reported for
most years from 1908 to 1946. See also (Bluestone R.).

(Goodwin Cr.) Tin
Port Clarence district Teller (8.0, 10.4-10.45)
MF-426, loc. 24 65935'N, 167°54'W

Creek drains east side of Cape Mtn. stock. Cassiterite in a narrow pay-
streak extending 1,000 ft downstream from Goodwin Gulch. Composite con-
centrate from USBM drilling program was about 58.5% tin. Only traces of
cassiterite upstream from mouth of Goodwin Gulch. Several hundred lb of
tin concentrate was recovered from a small depression at the head of Wales
Cr., a tributary not shown on available maps. Includes reference to (Wales
Cr.).

(Goodwin Gulch) Tin
Port Clarence district Teller (7.8-8.0, 10.4)
MF-426, loc. 24 65°35'N, 167°54'-167°56'W

Drains part of Cape Mtn. near old Bartels lode-tin mine. Goodwin Gulch
and/or Cape Cr. were mined in most years from 1924 to 1942; total pro-
duction was concentrates containing about 660 tons of tin. The entire
gulch was mined from mouth to headwater forks; much cassiterite in south
headwater fork, but very little in north fork. Not enough water for min-
ing; gravel hauled to Goodwin Cr. or to Bering Sea beach for processing.

MF-426, loc. 14 (in part)

A granite stock nearly 2 mi in diameter and felsic and mafic dikes and
sills intruded limestone, slate, and schist, Lime-silicate rocks de-
veloped at granite-limestone contacts. Minerals in contact zone include
fluorite, quartz, hematite, cassiterite, pyrite, chalcopyrite, pyrrhotite,
arsenopyrite, galena, sphalerite, paigeite, idocrase, topaz, gold, silver,
stibnite, limonite, malachite, ilmenite, chalcocite, scheelite, magnetite,
rutile, stannite, pyrolusite, cinnabar, zinnwaldite, cerussite, scapolite,
tourmaline, and a secondary uranium mineral intermediate between metazeu-
nerite and metatorbernite (primary uranium mineral not indetified). Mona-
zite and zircon are common accessory minerals in the granite. A zone
1,000 ft long and 65 ft wide on the northeast part of the mountain con-
tains an average of 0.2% Sn, 0.3% Cu, and small to trace amounts of gold,
silver, lead, and zinc. Rock samples of metasomatized limestone contained
as much as 380 ppm Be; highest values from fluorite-tactite rock rich in
idocrase. Several shallow shafts and a few drifts, all before 1918, did
not result in any ore being mined. Includes references to: Eunson's
shaft, Vatney, (Vatney Gulch), Winfield.

(Eldorado Cr.) Fluorite, Monazite, RE, Thorium, Tin,
Tungsten, Uranium

Serpentine district Teller (20.4-20.7, 16.8-16.95)

MF-426, locs. 60-63 65°56'N, 166°07'-166°0O9'W

Drains Ear Mtn. granite stock and contact zone. Placer concentrates con-
tain cassiterite, scheelite, monazite, xenotime, zircon, fluorite, and
magnetite. DMEA exploration caused USBM to conclude that the placers are
not minable. Maximum radioactive content of gravel in place was 0.00024%
eU. Panned concentrate sample with 0.29% eU contained 0.02% U; the rest
of the radioactivity assumed to be due to Th.

(First Chance Cr.) Tin
Port Clarence district : Teller (7.7-7.8, 10.1-10.3)
MF-426, loc. 25 65°35'N, 167956'-167°57'W

Headwaters drain contact zone around Cape Mtn. stock, but cassiterite in
placers was probably derived from contact zones next to acidic dikes or
from the dikes themselves about 2,000 ft upstream from mouth of creek.
Exploration indicated a maximum of 2.7 1b tin per yd? in placer deposit.
Has been some mining; production probably credited to Cape Cr.

MF-426, loc. 1 65°35'N, 167°59-168°00'W

Cape Mtn. is a Mesozoic granite stock intruded into limestone overlain on
top of mountain by schist. Pluton notcompletely unroofed; contains xeno-
liths. Many apophyses and granitic dikes. Contact-metamorphosed aureole
200-300 ft wide and alteration along faults. Tin lodes near contact of
granite and limestone include quartz veins and partially replaced lime-
stone and granite; cassiterite only tin mineral reported. Other minerals
include tourmaline, quartz, calcite, pyrite, pyrrhotite, fluorite, scapo-
lite, sphalerite, scheelite. Much exploration, 1903-09, resulted in more
than 1,000 ft of underground workings and the constructuon of two mills.
Total production was about 10 tons of concentrate that contained about 6
tons of tin worth $6,819. Was source of placer tin in Cape Cr. and Goodwin
Gulch (production through 1941 was about 650 tons of tin) and other streams.
One aldreference (Hess, 1906, B 284) mentions gold ore said to have been
worth $180 per ton; no more recent reference mentionsany gold. Anomalous
amounts of beryllium in sediment samples, but no beryllium minerals re-
ported. Includes references to: Bartell(s), Bartels (Tin Mining) Co.,
Empire Tin Mining Co., U.S. Alaska Tin (Mining) Co. See also: (Cape Cr.),

(Christophosen Cr.) Graphite

Port Clarence district Teller (24.85-25.0, 1.0-1.1)
65°02'N, 165938'-165°39'W

Paleozoic or older quartzose schists and other metamorphic rocks contain
lenses of graphitic schist and graphite. Entire zones (up to 25 ft thick)
contain as much as 10% graphite; lenses contain 50%-90% coarse graphite in
flakes several mm in diameter. About 120 tons of graphite was shipped in
1912 and about 300 tons more was ready to ship. All had been hand sorted.
Inferred resource for 3 mi of mountain front is 65,000 tons of material
containing about 60% graphite by volume. Includes references to: (Graphite

Data for mines, prospects, and mineral occurrences in area are so inter-
twined that most are summarized here rather than separately for each de-
posit. Area underlain by limestone intruded by granitic pluton, which is
exposed only in a small boss near Tin Cr. and in a cupola encountered in
underground workings of Lost River mine, associated apophyses and dikes,
and lamprophyre dikes; cut by thrust and other faults. In Lost River
mine there are cassiterite, wolframite, and sulfide minerals along a grei-
senized porphyry dike, cassiterite~ and wolframite-bearing greisen in the
cupola, and stockworks of tactite, beryllium-fluorite rock, and quartz-
topaz veins in limestone. At Camp Cr. is a tabular zone of beryllium-
fluorite vein and replacement bodies in faulted limestone; sulfide minerals
have been encountered at depth; this body contains more than 6 million

tons grading more than 30% CaF7. At the Yankee Girl prospect a gossan in
limestone contains lead minerals, cassiterite, fluorite, and sulfide min-
erals; sample assayed small amounts of gold and silver. A wolframite-topaz
lode in Lost R. valley is probably localized along a fault zone in lime-
stone; minerals identified include topaz, fluorite, wolframite, argenti-
ferous galena, stannite, and stibnite. A nearby iron-enriched zone con-

Country rock is slate, shale, phyllite, schist, and limestone cut by

small greenstone bodies and an altered granite porphyry dike. Lodes con-
sist of quartz veinlets containing clay minerals, cassiterite, fluorite,
tourmaline, pyrite, arsenopyrite, and stannite. Accessory minerals that
are common in other tin deposits of Seward Peninsula are absent; even
fluorite is much less common. Lode prospects consisting of shallow shafts
and trenches failed to find ore. There is an unconfirmed report that one
ton of ore from the Eureka claim was taken to York. Most streams that
drain Potato Mtn. carry cassiterite; Buck Cr. was a major producer. In-
cludes references to: Alan Dale, Daisy, Eureka, Red Fox.

Introduction

This report was prepared as a supplement to a 1975 report which
summarized data on mineral occurrences in the Teller quadrangle, Alaska
(Cobb, E. H., 1975, Summary of references to mineral occurrences (other
than mineral fuels and construction materials) in the Teller quadrangle,
Alaska: U.S. Geological Survey Open-file Report 75-587, 141 unnumbered
p-)- As a result of suggestions from users of the series of which the
1975 report is a part, this supplement is released in two parts; Part A,
which presents summaries of data to January 1, 1980, and Part B, which
consists of reference lists for each occurrence.

In Part A data from reports released between the cut-off date
(January 1, 1975) for the original report and January 1, 1980 have been
incorporated in rewritten or new summaries where appropriate; if there
are no new data on a deposit the original summary is repeated or a new
reworded version is substituted. For each deposit the name, list of
mineral commodities, and location data are in the same format as in the
1975 report. Also included is an updated list of synonyms, owner, oper-
ator, and claim names.

In Part B citations are in standard bibliographic format with the
exception that references to reports and maps in numbered publication
series also show, in parentheses, an abbreviation for the report or map
series and the number of the report or map. Abbreviations used are:

Citations to the principal references used in preparing summaries
in Part A are preceded by an asterisk.

Because the form of citation used in the reference list for each
deposit constitutes sufficient identification for each numbered report or
map to allow it to be found easily in most libraries, the general refer-
ence list in this report consists only listings of reports without formal
identifying numbers. Numbers given to U.S. Geological Survey Open-file
Reports listed with complete titles are informal and used mainly in the
Branch of Alaska Geology of the Geological Survey.

thick, 50 tons mined and shipped in 1916 from a pit on Graphite Cr. A
sample of schist in the pit (collected in 1943) contained 11.97% graphite,
75% of which was coarser than 30 mesh; a sample from a high-grade lens
contained 58.64% graphite, of which 85% was coarser than 30 mesh. For
summary of regional data applicable to this occurrence see (Christophosen
Cr.). Includes references to: Alaska Graphite (Mining) Co., (Glacier Can-
yon), (Glacier Cr.).

(Grouse Cr.) Gold, Tin
Port Clarence district Teller (11.05-11.2, 11.1-11.2)
MF-426, loc. 29 65938'N, 167927'-167928'W

Creek and tributaries drain part of Potato Mtn. Was mined between mouths
of Buck Cr. and East Fork. Production reported with that from Buck Cr.
Dredge operated from 1916 to 1919 or 1920. Some nonfloat mining as re-
cently as 1954. Gravel mined contained a little gold (probably less than
5¢ worth per yd3), hematite, and magnetite. For data on regional geology
and production see (Buck Cr.). Includes references to: (Skookum Cr.),
(Sterling Cr.).

(Henry Cr.) Copper
Kougarok district Teller (28.0, 11.6)
MF-426, loc. 18 65°37'N, 165°08'W

Silicified contorted carbonate rock above thrust faults contains minute
amounts of copper sulfides along joints; some copper stain. Two small

adits. This prospect probably is not the Worcester prospect of Mertie,
1918 (B 662). Name not used in all references listed in Part B.

(Hunter Cr.) Gold
Port Clarence district Teller (27.7, 8.0)
MF-426, loc. 20 65°25'N, 165°12'W

Traces of gold in altered limestone with quartz veinlets at base of thrust
block. Name not used in all references listed in Part B.

Idaho Copper, Fluorite
Port Clarence district Teller (13.3, 8.0)
MF-426, loc. 7 65°27'N, 167°11'W

Fluorite, pyrrhotite, and chalcopyrite are in an irregular shattered zone
15 ft thick in limestone. See also (Lost R.); at least one reference
listed in Part B is garbled and may be to Yankee Girl.

tains uraniferous limonite, hematite, goethite, and mimetite; radioactiv—
ity of 0.06% eU reported. On Tin Cr. beryllium minerals occur in replace-
ment veins and veinlets in marble near the granite boss; tactite generally
low in Be except where cut by fluorite veins; lodes in limestone near
granite contact contain sulfide minerals and cassiterite. On Cassiterite
Cr. and upper Lost R. placer deposits derived from the lodes of the immed-
iate Lost River mine area have been mined. Production has been about 350
tons of tin and some tungsten from lode sources (mainly the Cassiterite
dike in the Lost River mine) and about 175 tons of tin and 20 tons of

WO3 from placers between 1941 and 1955. Lode-tin resource estimates are
more than 18,000 tons of metallic tin in material containing 1.0% or more
tin and about the same amount in lower grade material; there are also

large resources of tungsten, beryllium, and fluorite. Minerals reported
from the Lost R. area include arsenopyrite, bismuthinite, chalcopyrite,
galena, molybdenite, pyrite, pyrrhotite, sphalerite, stannite, stibnite,
cassiterite, geothite, hematite, ilmenite, magnetite, mimetite, pyrolusite,
scheelite, wolframite, bertrandite, beryl, chrysoberyl, danburite, euclase,
milarite(?), phenacite, azurite, cerussite, malachite, diaspore, fluorite,
garnet, humite, idocrase, kaolinite, lepidolite, quartz, rutile, sericite,
topaz, tourmaline, and zinnwaldite; of these those with the greatest poten-
tial for economic interest (based on composition and quantity) are cassit-—
erite, fluorite, wolframite, and chrysoberyl. Includes references to:
