Report on Progress of Investigations of Mineral Resources of Alaska in 1904

Description: From letter of transmittal: The report contains fourteen papers, prepared by ten members of the geologic corps, who have been engaged in Alaskan investigations during the last year. In this report an attempt has been made to summarize the economic results of last season's field work. Geologic matter has been entirely excluded, except where it has a direct bearing on the subjects under discussion. While such a report can have no permanent value, other than as a record of mining conditions during the year, it is believed that its prompt publication will help the mining industry of Alaska.

Past Lode-Gold Production from Alaska

Description: From abstract: This report presents an analysis of the statistical records of the Geological Survey regarding the production of lode gold from the Territory of Alaska for the period 1882 to 1937, inclusive. During that time lode gold to the value of $172,368,000 had been mined. The history of the discovery of lode gold and the early developments in lode-gold mining in each of the various districts is outlined briefly, and the production of lode gold in each of the geographic subdivisions is tabulated fully for each year, as far as the records and the practices of the Geological Survey permit.

The Girdwood District, Alaska

Description: From abstract: The Girdwood district has been known for about 35 years to contain placer gold, but the source of the gold in veins was not discovered until about 1909. When the Alaska Railroad was completed through Girdwood it was hoped that the improved transportation facilities would enable the lode mines to operate at a profit and also to furnish tonnage to the railroad. Production from the quartz veins, however, has been negligible, although one placer mine has been operating steadily for several years.

Mineral industry of Alaska in 1934

Description: From Introduction: "The value of its mineral resources has long been recognized as a matter of concern in the welfare of every nation, and all wise governments almost from time immemorial have taken steps to find out about, utilize, and safeguard such of these natural resources as lie within their own boundaries or to acquire rights in those they need that lie outside those boundaries. Obviously one of these lines concerns itself with the record of present performance-how much of the different mineral commodities is the country at present producing, where does this production come from and what are the facts as to the current developments in the industry? To answer some of these questions authoritatively is part of the work of the Alaskan branch of the Geological Survey, and answers to those questions for the year 1934 are given in the accompanying report."

Tin Deposits of Irish Creek, Virginia

Description: From abstract: Cassiterite was discovered along Irish Creek in the Blue Ridge in the northern part of Rockbridge County, Va., in 1846, but active prospecting and development work were not begun until 1884. The production has been small, probably less than 1,000 tons of ore, and has come chiefly from workings on Panther Run, a small tributary near the headwaters of Irish Creek.

Mineral Industry of Alaska in 1935

Description: From introduction: The record of the Alaska mineral industry for 1935, here presented, is supplemented by records for earlier years, because in that way certain trends may be recognized which are not only of historical significance but are also useful in suggesting the course that the industry is likely to take in the future. This is a continuing service that has been rendered by the Geological Survey from almost the earliest years of active mining in Alaska, and the present report is the thirty-second of the series.

Mineral Deposits Near the West Fork of the Chulitna River Alaska

Description: From abstract: The area in the vicinity of the West Fork of the Chulitna River, Alaska, one of those examined in 1931 in connection with the study of mineral resources in districts tributary to the Alaska Railroad, contains numerous prospects but, as yet, no productive mines. Its placer deposits are negligible but some of its lodes may prove valuable for gold and silver and perhaps also for copper and arsenic.

Occurrences of Molybdenum Minerals in Alaska

Description: Abstract: In the accompanying report reference is made to all of the deposits in Alaska in which molybdenum minerals have been definitely recognized and reported. None of the deposits have been mined commercially, and none of them have been prospected thoroughly enough to afford quantitative estimates as to their tenor and potential reserves ; in fact, at only a few of the localities has there been more than surficial testing. Forty-one separate and distinct localities where molybdenum minerals occur are listed, and the available information on factors of geologic significance regarding each occurrence is given. A small-scale map of Alaska on which the various localities are indicated forms part of the bulletin, and in the text are extensive references to the various published reports and records of the Survey upon which the statements are based. In spite of the widespread distribution of molybdenum mineralization in Alaska, the remoteness of many of the localities, their handicap through dearth of transportation facilities and labor supplies, and the already wellsupplied condition of the American market for molybdenum ores discourage the early development of any of the known deposits or search for them in unsurveyed areas. These draw-backs will doubtless become -less important factors as the settlement and development of Alaska as a whole takes place. It is, therefore, with a view to the future that one must consider these deposits, and from that standpoint it becomes evident that some of them merit watchful consideration.

Mineral Resources of the Behind the Rocks Wilderness Study Area, Grand and San Juan Counties, Utah

Description: Abstract: The Behind the Rocks Wilderness Study Area (UT-060-140A) consists of 12,635 acres in Grand and San Juan Counties, Utah. The study area has inferred subeconomic resources of potash and halite in the subsurface, and sandstone on the surface. The study area has high potential for undiscovered resources of oil and gas, low potential for undiscovered uranium, copper, vanadium, gold, silver, other metals, and geothermal energy, and unknown potential for the rare-earth mineral, braitschite. There is no resource potential for potash or halite (beyond the previously mentioned inferred resources) or for coal.

Geology of the Portage Pass Area, Alaska

Description: Abstract: The Portage Pass area is in south-central Alaska, and includes part of the narrow neck of land that joins the Kenai Peninsula with the mainland to the north. This region is in general mountainous, elevations ranging from sea level to more than 4,000 feet on the peaks bordering the area. Several glaciers, all of which are apparently receding, extend into the area. Vegetation, chiefly alder and cottonwood on the valley lowlands and some spruce and hemlock on the lower slopes, extends to an elevation of about 1,000 feet, above which the slopes are bare except for occasional clumps of brush. The bedrock of the entire area is slate, argillite, and graywacke, apparently part of the same great series that extends from the Kenai Peninsula into the Prince William Sound region and is at least in part of Cretaceous age. The only igneous rocks recognized in the area are a few acidic dikes and a small diabase dike. Small, irregular quartz veinlets are widespread. The structure is not only complex but, owing to extensive metamorphism, is in many places obscure. A general northeast strike and steep to vertical dips of both bedding and cleavage planes are the rule, but there appears to be some broad folding along steeply northeast-pitching axes. Although no large faults have been recognized, much movement has occurred along many small faults, shear zones, and bedding planes. All observed faults and shear zones trend northeastward. There are no mines in this area. Some mineralization of quartz veins was noted at a few places, and some prospecting has been done, but no workable deposits are known.

Mineral Resources of the Sleeping Giant Wilderness Study Area, Lewis and Clark County, Montana

Description: From abstract: A mineral resource survey was conducted in 1987 by the U.S. Geological Survey and the U.S. Bureau of Mines to evaluate mineral resources (known) and mineral resource potential (undiscovered) of the Sleeping Giant Wilderness Study Area (MT-075-111) in Lewis and Clark County, Montana. The only economic resource in the study area is an inferred 1.35-million-ton reserve of decorative stone (slate); a small gold placer resource is subeconomic. A high resource potential for decorative slate exists directly adjacent to the area of identified slate resource and in the northeastern part of the study area. The rest of the study area has a low potential for decorative slate. The westernmost part of the study area has a moderate resource potential for copper and associated silver in strata-bound deposits in green beds and limestone; potential is low in the rest of the study area.

Mineral Resources of the Farlin Creek Wilderness Study Area, Beaverhead County, Montana

Description: Abstract: The Farlin Creek Wilderness Study Area (MT-076-034) is in the south-central Pioneer Mountains about 24 miles west-northwest of Dillon, Beaverhead County, southwestern Montana. At the request of the U.S. Bureau of Land Management, an area of 610 acres (less than 1 square mile) was investigated by the U.S. Geological Survey and the U.S. Bureau of Mines in 1984. The area contains no mines or prospects, no visible evidence of mineralization, and no identified mineral resources. Geophysical evidence suggests that three parts of the area have moderate mineral resource potential for undiscovered resources of molybdenum. The entire area has a low resource potential for all other metals and for all nonmetals, fuels, and geothermal energy.

Mineral Resources of the Clover Mountains Wilderness Study Area, Lincoln County, Nevada

Description: From abstract: At the request of the U.S. Bureau of Land Management, approximately 84,165 acres of the Clover Mountains Wilderness Study Area (NV-050-139) was evaluated for mineral resources (known) and mineral resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area;" any reference to the Clover Mountains Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The study area is located in southern Nevada, in Lincoln County, about 90 mi northeast of Las Vegas. No identified mineral resources exist inside the study area, although gold, silver, and copper resources are found immediately to the west at the Pennsylvania mine.

Some Lode Deposits in the Northwestern Part of the Boise Basin, Idaho

Description: From abstract: The report is limited to the geology of lode deposits in the northwestern part of the Boise Basin which are in or near mines that were in operation at the time of visit, in 1930. Owing to the recent inactivity of the formerly rich placer (leposits, there is nothing essential regarding them to add to Lindgren's report published in 1898. The area studied is underlain by granitic rock of the Idaho batholith, which is cut by dikes of Miocene(?) age. These dikes are dacite porphyry (intruded early) ; rhyolite porphyry, granophyre porphyry, and granite porphyry (closely related in character and age) ; and several basic varieties (of which some, at least, are of relatively late origin). Diorite porphyry dikes, of undetermined age but probably older than all of those named above, are also present.

Mineral Resources of the Ruby Mountains Wilderness Study Area, Madison County, Montana

Description: From abstract: A mineral resource survey of the Ruby Mountains Wilderness Study Area (MT-076-001) was made in 1984- 85. Thirty-two million tons of subeconomic mineral resources that average 21 percent iron occur in the Kelly iron deposit and constitute an identified resource adjacent to the southeasternmost edge of the study area. Moderate and high mineral resource potential for talc deposits occur within a large body of Archean (see geologic time chart in appendix) marble in the central part of the study area (fig. 1). The study area has a low mineral resource potential for uranium and for oil and gas sources. No phosphate deposits exist in the study area.
