Mineral Resources Tasmania: Tasmania, the best place in the world

Considering the challenges that mineral and metallic resources represent for the building sector, there is a need to propose decision-support tools to building stakeholders. One of the possibilities could be to integrate an indicator of pressure on mineral resources in an absolute environmental sustainability assessment (AESA) approach, using life cycle impact assessment (LCIA) methods. This paper will analyze the existing LCIA indicators that can be used to represent the impact on mineral resources of new constructions, with a case study on new buildings in France in 2015. This analysis aims to find out whether the existing LCIA methods dealing with mineral and metallic resources issues are adapted to the specific stakes of the building sector in an AESA approach. The AESA approach considered is the one proposed by Bjørn and Hauschild. Several steps are detailed in this paper. Firstly, bibliographic research was carried out to identify existing LCIA methods related to the mineral resources. Secondly, selection criteria were defined in order to select those LCIA methods relevant for the building sector. Thirdly, the scope of the case study was defined and its inventory analysis was conducted using the Ecoinvent 3.5 database, selecting only the mineral and metallic input flows. Finally, the comparison between the inventory of mineral and metallic flows issued from the inventory analysis and the substances considered in the selected LCIA methods was effected. The results show that none of the existing LCIA methods are compatible with the aim of developing an LCIA indicator for mineral and metallic resources that is compatible with an AESA approach, in particular for the building sector.

Mineral resource evaluation is one of a whole spectrum of quantitative methods which have been used since biblical times for the purpose of improving the process required to aid problem-solving and to increase the quality of strategic management decisions at all levels. Such evaluation leads to the classification of mineral resources. It is important to have a clear knowledge of how mineral resources are classified and what the classification nomenclature actually means to ensure decisions are based on a sound understanding of criteria applied. As interest for investment in mineral resource development spreads into Eastern Europe and the former Soviet Union, the need for some form of harmonization in terminology, nomenclature, criteria, as well as the approach to the classification process for the definition of mineral resources has again been highlighted. The approach to quantitative studies is discussed, and guidelines are given that may improve mineral reserve and resource estimates so that implementation failure of mining projects can be avoided. Approaches to the classification of mineral resources are reviewed along with the uses made of such mineral resource information. The argument is put for a standard approach to mineral resource classification and consistency of international nomenclature with a discussion of some of the related problems. Principles are established which may suggest a way forward illustrated by a recent major resource assessment project.

At request of U.S. Bureau of Land Management, approximately 39,420 acres of Skedaddle Mountain Wilderness Study Area (CA-020-612) were evaluated for mineral resources (known) and mineral resource potential (undiscovered). In this report, studied is referred to as study area or simply the study any reference to Skedaddle Mountain Wilderness Study Area refers only to that part of wilderness study for which a mineral survey was requested by U.S. Bureau of Land Management. Field work was carried out in 1985 to assess mineral resource potential of area. Demonstrated subeconomic perlite resources are about 184,000 short tons in and adjacent to western part of study area. There are six areas of mineral and (or) geothermal energy resource potential in Skedaddle Mountain Wilderness Study Area. Geologic and geochemical evidence suggests that study has potential for occurrence of silver, gold, mercury, and antimony metallic deposits. The central part of Spencer Basin, upper Thousand Springs Canyon, and south fork of Wendel Canyon have high mineral resource potential for gold, silver, mercury, and antimony while surrounding these locations has moderate mineral resource potential for same metals. An in Wendel Canyon has moderate mineral resource potential for perlite, and an adjacent to south has low mineral resource potentialforthe same commodity. The Skedaddle Mountain Wilderness Study Area includes part of Wendel-Amedee Known Geothermal Resource Area. The southwest corner of study has moderate resource potential for geothermal energy and much of west half of study has low potential for geothermal energy. There is no oil or gas resource potential in study area. Character and Setting The Skedaddle Mountain Wilderness Study Area is located in eastern part of Modoc Plateau in Lassen County, northeastern California, and Washoe County, northwestern Nevada (fig. 1). The study encompasses 39,420 acres 25 mi east of Susanville, Calif. It is bounded on three sides by dirt roads; south boundary parallels Wendel Road. The Skedaddle Mountains lie in northern part and Amedee Mountains lie in southern part of study area. Elevations range from 4,3 00 ft at base of Amedee Mountains to 7,680 ft at summit of Hot Springs Peak in Skedaddle Mountains. Steep rim-rock walls and taluscovered canyons are common along the.west edge of area; rest of study is moderately sloping. Vegetation is sparse, consisting mainly of desert sage-scrub species. The rocks in study consist mostly of Tertiary (see appendixes for geologic time scale) basalt, andesite, dacite, rhyolite, and lahar deposits. South of study lakebed features, including tufa deposits and strandlines from Pleistocene Lake Lahontan, are present. The central part of Mineral Resources of Skedaddle Mountain Wilderness Study Area, Lassen County, California, and Washoe County, Nevada C1 Spencer Basin is underlain by highly altered volcanic rocks which probably originally consisted of andesite, dacite, and lahar deposits. Identified Mineral Resources The identified resources in Skedaddle Mountain Wilderness Study Area consist of 46,000 tons of measured subeconomic resources and about 138,000 tons of indicated subeconomic resources of perlite. Additional nonmetallic occurrences present in study consist of basalt, pozzolan, stone, and sand and gravel. There are no identified resources of these commodities and they are not currently of economic significance. There are no identified resources of metallic minerals in study area, but metallic mineral occurrences present in and near study consist of small amounts of gold and mercury in vein-type deposits. The gold and mercury occurrences and perlite resources are spatially related to a volcanic center in Skedaddle Mountains. There are no known mines or mining operations in study area. None of prospects or claims in or within 1 mi of study have recorded production. At least 276 recorded lode, 6 located but unrecorded lode, and 29 placer claim locations are present in and within about 1 mi of study area. Approximately 191 of these are in study area; four of these were actively held in 1985. None of study was being explored by private industry in 1985, but prospects in Skedaddle Mountains may be targets for future exploration for both precious metals and perlite. 120°30' 120° 15' 120°00'

The article offers a functional typification of Podilsk economic and geographical area mineral resources (MR), based on taking into account their influence on the participa- tion of certain industries in the territorial division of labor, complex-forming properties and the realized activity (degree of deposit development) of certain types of minerals and differs from the general Ukrainian (Syvyi, 2011) with several features. Thus, three groups of mineral resources are determined in particular, ac- cording to the first feature: international, national and local; according to the second all types of mineral raw materials are grouped into three classes a, b, and c; three types of mineral deposits a, b and c are identified depending on the degree of development. Besides, the criteria are proposed for classification of some raw materials as strategic. In the presented variant of typification of mineral resources of the region, an attempt was also made to approximate geographical and geological positions in classifications, which will help to define clearly the role and place of mineral resources in the territorial and sectoral structures of the economy, to determine national priorities in the development of mineral and economic resources of the country-raw materials experience in geological practice. The first group (raw material of international importance) in Podillia includes valuable mineral waters such as Naftusia, radon, and sulfide waters, kaolins, graphite, facing stones from magmatic rocks, i.e. raw materials with significant (modern or potential) export potential. The second group (raw material of national importance) is the largest, with the vast majority of mineral resources explored in the region: most types of mineral waters, cement raw materials, construction stones, agrochemical raw materials, some types of technological raw materials and so on. Many of them are characterized by high realized activity, a large number is developed in insufficient quantities or generally not developed because of various reasons (lack of demand, environmental problems, depletion or insufficient exploration of stocks, etc.). The local raw materials include a small number of mineral types - ameliorant, construction sands, and others. Mineral resources with high complex-forming properties are almost absent in the region (except for Naftusia mineral waters, where large recreational complexes are formed). Class B (medium complex-forming properties) includes mineral resources, small mining sites, and centers that are formed based on them (cement raw materials, agrochemical raw materials, kaolins, mineral waters with specific components, etc.). However, the largest amount of mineral resources of the region is not marked by explicit complex-forming properties and is classified as class C. The article draws generalized conclusions about the functional structure of mineral resources of the region, which are revealed by their typification, the priority directions of investments in geological prospecting are offered, which should help to increase and optimize the mineral base of the region.

At the request of the U.S. Bureau of Land Management, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field studies of 20,500 acres of the Rincon Wilderness Study Area. The Rincon Wilderness Study Area (OR-002-082) is located between Callow Valley and the Pueblo Mountains in southeastern Oregon. In this report, the area studied is referred to as the "wilderness study area," or simply the "study area." Field work was conducted by the U.S. Geological Survey during 1986 and 1987, and by the U.S. Bureau of Mines during 1986, to evaluate the identified mineral resources (known) and the mineral resource potential (undiscovered) of the study area. No mineral resources were identified in the study area. However, the study indicates moderate potential for silver resources in a rhyolite ash-flow tuff exposed near the central part of the study area and high potential for sand and gravel resources in lake shoreline deposits along the northwest boundary of the study area. The entire study area has low potential for geothermal resources and no potential for oil and gas. Character and Setting The Rincon Wilderness Study Area is located along Callow Rim approximately 90 mi south of Burns, Oregon, and 10 mi west of Fields, Oregon (fig. 1). Callow Rim is a fault scarp that rises 1,000 to 1,900 ft above Callow Valley and forms the entire lenglh of the impressive 60-miManuscript approved for publication, June 22, 1988. long easl valley wall. A large displacement faull at Ihe base of Ihe escarpment is Ihe dominanl geologic structure in the region and forms Ihe west margin of Ihe 30by 90mi, north-trending Sleens-Pueblo Mountains fault block. The area east of Ihe rim is characterized by a gently southwesl-tilied dip slope cul by several west-flowing creeks (fig. 1). Middle Miocene-age basalt flows form the 1,600-flhigh Callow Rim escarpment and are Ihe oldesl rocks exposed in Ihe sludy area. The middle Miocene ranges from 11.2 lo 16.6 million years before presenl, or Ma; see appendixes for geologic lime chart. A sequence of andesile flows, luffaceous sedimenlary rocks, and ash-flow luffs overlies Ihe basall flows. The straligraphic section is capped by younger andesile flows of lale Miocene and Pliocene age (Walker and Repenning, 1965). The western part of the study area extends into Callow Valley, a broad, irregular-shaped graben. Pleistocene shoreline deposits and Holocene dunes are exposed in the valley. Identified Resources No mines, claims, or prospects were found, and no mineral or energy resources were identified within or adjacent to the study area. Mineral Resource Potential A rhyolite ash-flow tuff near the central part of the study area (fig. 2) has moderate potential for silver resources. One unaltered sample of this tuff contains Mineral Resources of the Rincon Wilderness Study Area, Harney County, Oregon E1

The Blitzen River Wilderness Study Area (OR-002-086E) is located along the western slope of Steens Mountain in southeastern Oregon. At the request of the U.S. Bureau of Land Management, the U.S. Geological Survey and U.S. Bureau of Mines conducted field studies of 21,658 acres of the Blitzen River Wilderness Study Area. In this report, the area studied is referred to as the "wilderness study area," or simply the "study area." Fieldwork was conducted by the U.S. Geological Survey during 1986 and 1987 and by the U.S. Bureau of Mines during 1986 to evaluate the identified mineral resources (known) and the mineral resource potential (undiscovered) of the study area. No mineral resources were identified in the study area. However, the study indicates moderate potential for geothermal energy resources along northwest-trending fault zones in the western part of the study area. The study area has no potential for oil and gas resources. Character and Setting The Blitzen River Wilderness Study Area is located along the west slope of Steens Mountain (fig. 1), 55 mi south of Burns, Oreg., and 35 mi northwest of Fields, Oreg. The study area ranges in elevation from 4,200 ft where the Donner und Blitzen River enters Blitzen Valley to 6,500 ft above sea level along the easternmost boundary. West of the study area, the lower slope of Steens Mountain forms a Manuscript approved for publication June 22, 1988. gentle west-tilted plateau that ends abruptly at Callow Rim along the east edge of Callow Valley. Ten miles east of the study area the upper slope rises more than 3,100 ft to the crest of Steens Mountain, 9,670 ft above sea level. Several northwest-flowing rivers and creeks have cut deep gorges into the plateau (fig.l). The Donner und Blitzen River is the largest river in the region and collects most of the tributary drainage on the west side of Steens Mountain. The river flows north through the western part of the study area into the Blitzen Valley (fig. 1). The oldest rocks exposed in the study area are basalt flows of middle Miocene age (11.2 to 16.6 million years before present, Ma; see appendixes for geologic time chart). The basalt flows that underlie the entire study area are overlain in the northern part by late Miocene rhyolite ash-flow tuff and basalt flows. Identified Resources No mines, claims, prospects, or mineralized zones were found, and no mineral or energy resources or occurrences were identified wilhin or adjacent to the study area. Mineral Resource Potential Hot springs issue from a northwest-trending fault zone 2 to 5 mi north of the study area. This same fault zone extends southeasl ihrough ihe western part of the study area. Areas along the fault zone and parallel fault zones have moderate potential for geothermal energy resources. The study area has no potential for oil and gas resources.

New insights into the marine minerals and energy resources of the Chilean continental shelf with an environmental approach

In 1984 and 1985, at the request of the Bureau of Land Management, the U.S. Geological Survey and the U.S. Bureau of Mines conducted surveys to assess the mineral resources (known) and mineral resource potential (undiscovered) of 2,ZOO acres of the 5,838acre Pinnacles Wilderness Contiguous Wilderness Study Area (CA-040-303) in the southern Gabilan Range near Hollister, Calif..In this report, the area studied is referred to as "the wilderness study area", or simply "the study area."No active mines, prospects, or identified mineral or energy resources were identified in the study area.Two areas were determined to have low potential for mineral resources.One of these areas has low potential for gold, and silver resources.The other has low potential for diatomite and oil and gas resources.

The Upper Deep Creek Wilderness Study Area (ID-111-044) is located on the northern Owyhee Plateau in southwest Idaho and encompasses 11,510 acres, of which the U.S. Geological Survey and the U.S. Bureau of Mines were asked to 5,700 acres. Hereafter, the terms study and wilderness refer pnly to the smaller acreage. Field work for this report was conducted in 1985 to assess the identified mineral resources (known) and mineral resource potential (undiscovered) of the area. No mines, prospects, or claims are located in the area and there are no identified mineral or energy resources. The area has moderate resource potential for small gold placers and low potential for gold and silver resources in epithermal (hydrothermal) deposits. The area also has low potential for tin and uranium resources; the southern part has low potential for diatomite resources. The potential for oil, gas, and geothermal energy resources in the area is low. Character and Setting The Upper Deep Creek Wilderness Study Area is located on the northern Owyhee Plateau of southwest Idaho (fig. 1), about 80 mi southwest of Boise. The terrain is characterized by a stream-dissected plateau, averaging about 5,300 ft in elevation, with several prominent canyons, including the 200to 400-ft-deep canyon of Deep Creek that extends the length of the area. The surrounding Owyhee Plateau is underlain by a thick (greater than 800 ft) flat-lying sequence of Miocene (see appendix for geologic time chart) rhyolitic ash-flow tuffs, basalt flows, and minor interbedded sedimentary rocks. A thick rhyolitic ashflow tuff is exposed in most of the area; the tuff is overlain in the southern part by a sequence of thin basalt flows and basal sedimentary rocks (fig. 2). Geologic and geophysical data indicate that the area lies within a large collapsed caldera. The ashflow tuff and overlying units are interpreted to be part of a post-collapse sequence that has filled and buried most of the caldera. A small (0.5 by 0.25 mi) basalt maar crater (Indian Lake, fig. 2) is located directly east of the area. Identified Resources No mining claims were located and no minerals were produced in the area. There are no identified mineral or energy resources within the area. Mineral Resource Potential There is moderate resource potential for placer gold resources obtained by recreational, suctiondredge methods along the Deep Creek stream bed (fig. 2); relatively high concentrations of particulate gold were identified in sand and gravel bars along the creek within the area. The entire area has a low potential for gold and silver resources in epithermal deposits (fig. 2). This is indicated by weak, sporadic geochemical anomalies, and the presence of placer gold. Altered

Can renewable energy technology innovation promote mineral resources’ green utilization efficiency? Novel insights from regional development inequality

Renewable energies are promoted in order to reduce greenhouse gas emissions and the depletion of fossil fuels. However, plants for renewable electricity production incorporate specifically higher amounts of materials being rated as potentially scarce. Therefore, it is in question which (mineral) resources contribute to the overall resource consumption and which of the manifold impact assessment methods can be recommended to cover an accurate and complete investigation of resource use for renewable energy technologies. Life cycle assessment is conducted for different renewable electricity production technologies (wind, photovoltaics, and biomass) under German conditions and compared to fossil electricity generation from a coal-fired power plant. Focus is given on mineral resource depletion for these technologies. As no consensus has been reached so far as to which impact assessment method is recommended, different established as well as recently developed impact assessment methods (CML, ReCiPe, Swiss Ecoscarcity, and economic scarcity potential (ESP)) are compared. The contribution of mineral resources to the overall resource depletion as well as potential scarcity are identified. Overall resource depletion of electricity generation technologies tends to be dominated by fossil fuel depletion; therefore, most renewable technologies reduce the overall resource depletion compared to a coal-fired power plant. But, in comparison to fossil electricity generation from coal, mineral resource depletion is increased by wind and solar power. The investigated methods rate different materials as major contributors to mineral resource depletion, such as gallium used in photovoltaic plants (Swiss Ecoscarcity), gold and copper incorporated in electrical circuits and in cables (CML and ReCiPe), and nickel (Swiss Ecoscarcity and ReCiPe) and chromium (ESP) for stainless steel production. However, some methods lack characterization factors for potentially important materials. If mineral resource use is investigated for technologies using a wider spectrum of potentially scarce minerals, practitioners need to choose the impact assessment method carefully according to their scope and check if all important materials are covered. Further research is needed for an overall assessment of different resource compartments.
