Abstract:
ABSTRACT Several European countries instituted mining schools in the late 1700s, including France, Germany, Hungary, and Russia. However, since England’s mining industry was privatized with little government involvement, Great Britain was decades behind with the creation of a school of mines. In 1835, Henry De la Beche (1796–1855) became the first director of the Ordnance Geological Survey, precursor to the British Geological Survey. De la Beche used this position to advance geology’s professionalization, which would include the establishment of an applied geology museum, mining records storehouse, and a school of mines. The Museum of Economic Geology, displaying the country’s mineral resources and geology, was De la Beche’s first success. Founded in 1835, it opened to the public in 1841. The Mining Records Office opened in 1840 as a repository for plans of working and abandoned mines. An early public advocate for workers’ safety, De la Beche lobbied for government inspections of collieries, immediate reporting of mining accidents, and proper plans of mines. The School of Mines was De la Beche’s third accomplishment in geology’s professionalization. As an outgrowth of the museum, it was formally opened in 1851 along with the larger Museum of Practical Geology, the Museum of Economic Geology’s successor. De la Beche’s intent for the School of Mines—instruction as a combination of science and practice—seems modern in its approach. In 1843, funding was allocated for lectures on the practical applications of geology, but these were not implemented until the School of Mines opened in 1851. In his effort to educate everyone—from miner to mine owner—De la Beche transcended social boundaries and supported open, public lectures. As a result, some considered him a class traitor. De la Beche used his position to advocate for advancement of the mining industry to include miner safety and public education. Therefore, while the Royal School of Mines emerged later than many of its European counterparts, it was part of a systematic professionalization of geology, coupled with education and a public advocacy for mining participants.

Abstract:
Editor’s note: The Geology and Mining series, edited by Dan Wood and Jeffrey Hedenquist, is designed to introduce early-career professionals and students to a variety of topics in mineral exploration, development, and mining, in order to provide insight into the many ways in which geoscientists contribute to the mineral industry. Abstract Resource and reserve estimation is a critical step in mine development and the progression from mineral exploration to commodity production. The data inputs typically change over time and reflect variations in geoscientific knowledge as well as the modifying factors required by regulation for estimating a reserve. These factors include mineral (ore) processing, metallurgical treatment of the ore, infrastructure requirements for mine and workforce, and the transportation of processed products to buyers; others that will affect the production of metals and/or minerals from a deposit include economic, marketing, legal, environmental, social, and governmental factors. All are needed by the mining industry to quantify the contained mineralization within mineral deposits that likely warrant the significant capital investment required to build a mine. However, these resource and reserve data are estimates that change over time due to unpredicted variations in the initial inputs. Paramount to the two estimates are the quality and accuracy of the geologic inputs and the communication of these to the professionals tasked with making each estimate. Geostatistical processing of the grade of the resource has become a dominant element of the estimation process, but this requires transparent and informed communication between geologists and mining engineers with the geostatistician responsible for mathematically processing the grade data. Regulatory constraints also mean that estimated resources and reserves seldom capture the full extent of a mineral deposit. Similarly, co- and by-product metals and minerals that are commonly produced by mines may not be captured by resource and reserve estimates because of their limited economic contribution. This suggests that reporting standards for co- and by-products—particularly for the critical metals that may have a sharp increase in demand—need improvement. Finally, the importance of these data to the mining industry is such that informing investors and the broader public about the nature of resource and reserve estimates, and the meaning of associated terminology, is also essential when considering the global metal and mineral supply, and the role of mining in modern society.

Abstract:
The estimation of the mineral resources area (target area) number is an important part of mathematical geology. Total resource depends not only on the scale of the single target mineralization but is also proportional to the number of target area. In this paper, the target area quantitative algorithm was studied based on the domestic and abroad opinions. The Petersen capture model and Poisson model were introduced into the estimation of resource maternal capacity. In order to meet the requirements of the two models, sampling plan were re-designed and improved. Take 1/200,000 gold mines and metal (Cu, Ag, Pb, Zn) mineral resources prediction in Hebei Province as an example, two practical estimation models of the resource maternal capacity were established. Calculation shows that the results of Petersen capture model and Poisson model were similar and can be as an effective predictor of district resource capacity. Therefore, the bottleneck of regional resource total forecasting calculation method is solved.

Abstract:
Opencast mining industry very often extracts mineral resources below the groundwater table. Dewatering of excavations affects exploitable groundwater resources. It causes only temporal changes, but if they last several tens of years, local population is forced to modernize existing or even build new groundwater intakes. Mines discharge water into rivers, and local residents have problems with water supply. The municipality has the right not to agree for dewatering, but then it limits the activities of the mining industry. Therefore, it is very important to recognize not only the mining excavations affected by water inflow, but also the scope of hydrodynamic changes and their impact on groundwater intake facilities. The basic computational tool for prediction the effects of extraction of mineral resources below the water table should be a properly constructed mathematical model of a dewatered aquifer. The model should be stationary and should be used to prepare further forecasts for the assessment of damage caused by mining operations, depending on the progress in the exploitation of minerals. This will allow anticipating actions to cover possible losses in water supply to people, agriculture and the local industry. The authors present this problem and the attempts of such operations, based on the examples from the Gałęzice–Bolechowice–Borków and Łagów regions in the Holy Cross Mountains where numerous opencast mines of the Devonian limestones and dolomites are located.

Abstract:
Geography of mineral deposits and the distribution of chemical elements on the globe are characterized by heterogeneity. Mineral resources of the world, mineral deposits are devoted to a large array of publications of domestic and foreign specialists – geologists, geographers, geochemists, economists. During the mastering of the material, comparative-geographical, cartographic (analysis of maps of mineral resources, mineral resources in the context of continents and regions of the world), monographic (fundamental works of leading domestic and foreign geologists and resource scientists, geological and mineral reference books and dictionaries, multi-volume editions, devoted to the geology and mineral resources of individual countries and regions of the world) methods, systematic approach, in the processing and systematization of data used modern no computer technology. The explored deposits of mineral raw materials (actual and potential) form on the planet as separate local deposits, as well as geochemical zones – areas where concentrated economically valuable chemical elements and their compounds (minerals and rocks) are diverse in genesis (origin), stocks, exploitation possibilities. The largest of them are Appalachians in the USA – Western Hemisphere, High Velt in South Africa, Hibiny and Ural in Russia – Eastern Hemisphere. Leading countries in the territory where most of the geochemical raw materials are mined from the bowels are the USA (65 % of the total number of elements of the table), Russia (48 %), China (38 %), Canada (38 %), South Africa (30 %), Australia (27 %), Kazakhstan (19 %), India (14 %), Mexico (13 %). Systematized representations about the level of provision of mineral raw materials and minerals of individual countries and territories of the world. D. I. Mendeleev’s table and its mineral raw materials are presented as an objective factor of the international geographical division of labour. The given data reveal an adequate level of provision of countries and territories with mineral resources. The highlighted problem has confirmed the high density of interdisciplinary connections (geography, geology, geochemistry, economics, regionalisms). The given data can be implemented in the latest programs of reformed education in Ukraine.

Abstract:
Systematic information and in-depth knowledge of geological controls, mode of occurrences, distribution patterns and mineral association are very essential for exploring the new deposits and development of mineral resources of the country in general. In present study, an attempt has been made to clarify the geological controls of economic and sub-economic mineral deposits of Nepal. Investigation has shown that mineral deposits in Nepal Himalaya are controlled by particular geological conditions and tectonics. Till the date, economic potential of 63 mineral commodities from Nepal have been established by Department of Mines and Geology. Several economic to sub economic deposits of the country are explored and some are under mining process. Analysis of geological controls of above mentioned economic and sub-economic mineral deposits shows that they are either syngenetically or epigenetically confined to particular stratigraphic and tectonic units. These deposits are related in time and space to certain events of crustal movement representing different metallogenic epochs.

Abstract:
Abstract BHP Minerals discovered the Archean lode gold ULU deposit on the western margin of the High Lake Volcanic Belt in 1989. The greenschist to amphibolite facies mafic volcanic and sedimentary rocks on the property are folded into a 5 km-long anticline. There is a close spatial association of Au-As zones to the trace of this F2 ULU anticline. The largest of these auriferous zones, the Flood zone, is localized at the core of the fold. The southeast-trending Flood zone consists of several anastomosing lenses that have been traced for 435 m on surface. Overall, it dips steeply (70° to 80°) to the southwest and has been intersected to depths below 600 m. The hosting high-iron tholeitic basalt displays a lower amphibolite mineral assemblage of ferrohornblende + plagioclase + ilmenite with accessory quartz and epidote. Alteration minerals include biotite, chlorite, hornblende, actinolite-tremolite, and potassium feldspar (microcline) with minor calcite, epidote, tourmaline, and titanite. The highest gold values occur where brecciated basaltic wall-rock clasts are replaced by acicular arsenopyrite + quartz + K-feldspar. BHP Minerals completed 54,783 m of both exploration and resource development drilling before selling the ULU property to Echo Bay Mines in 1995. Development of ULU as a satellite deposit to Echo Bay’s Lupin mine began in 1996. A -15% ramp was extended to the 155-meter level, and 16,011 m of underground drilling were completed before the decline in gold prices forced a suspension of activities at ULU in August 1997. The current owners, Wolfden Resources Inc., drilled 18,569 m in 2004 to increase confidence in the resource blocks. Following this drill program, a revised resource calculated by an independent consultant determined that the ULU deposit contains an inferred/indicated mineral resource of 1,130,000 t grading 11.34 g/t gold (373,748 oz) to the 360-m level. The portal was re-opened in 2005 and a prefeasibility study is underway.

Abstract:
AbstractThe main metallic mineral resources of New Caledonia are hosted by the obducted Peridotite Nappe. Ni, Co, Cr and the Pt group elements (PGEs) are specific to this ultramafic terrane. Cr, as podiform chromitite in the uppermost mantle, is the only hypogene metal mined economically in the past. The largest chromitite deposits are located in the lherzolitic Tiébaghi Massif. Supergene Ni and Co deposits are concentrated by the tropical climate that has prevailed since the Miocene. New Caledonian lateritic Ni deposits account for 10% of the global Ni resources. Hydrous Mg silicate and oxide types coexist in a single deposit. A local genetic model based on geomorphological evolution is proposed. Sc is a prospective resource associated with these supergene deposits. The PGEs are a prospective resource associated with chromite, with potential in the hypogene, supergene and fluvio-littoral domains. Pt and Pd are the most significant elements. The transition zone between the upper mantle and crustal cumulates constitutes a regional Pt–Pd-enriched horizon. The concentrations are related to small disseminated chromite lenses in a pyroxene-rich lithology. The PGEs are concentrated in weathering profiles. The value of chromite-rich sands as placers or sand beach deposits might be enhanced by the occurrences of PGEs.

Abstract:
The research contained within this thesis was directed at examining the spectral properties of regolith-dominated terrains using airborne and proximal hyperspectral instruments. The focus of the investigation was to identify the mineralogy of the regolith and determine if surficial materials were indicative of the underlying bedrock in the regolithdominated terrain of the eastern Olary Domain, South Australia. The research area was constrained to a 250 km2 area around the Cu-Au mineralisation of the White Dam Prosect. Integrated remote sensing, using airborne hyperspectral datasets (HyMap), Landsat imagery and gamma-ray spectroscopy data, was performed to map regolith-landforms and extract information on surficial materials. Detailed calibration of the HyMap dataset, using a modified model-based/empirical line calibration technique, was required prior to information extraction. The White Dam area was able to be divided into: alluvial regolith-dominated; in situ regolith-dominated; and bedrock-dominated terrains, based on mineralogical interpretations of the regolith, using the remotely sensed hyperspectral data. Alluvial regions were characterised by large abundances of vegetation and soils with a hematite-rich mineralogy. Highly weathered areas of in situ material were discriminated by the presence of goethite and kaolinite of various crystallinities, whereas the bedrock-dominated regions displayed white mica-/muscovite-rich mineralogy. Areas flanking bedrock exposures commonly consisted of shallow muscovite-rich soils containing regolith carbonate accumulations. Traditional mineral mapping processes were performed on the HyMap data and were able to extract endmembers of regolith and other surficial materials. The Mixture Tuned Matched Filter un-mixing process was successful at classifying regolith materials and minerals. Spectral indices performed on masked data were effective at identifying the key regolith mineralogical features of the HyMap imagery and proved less time consuming than un-mixing processes. Processed HyMap imagery was able to identify weathering halos, highlighted in mineralogical changes, around bedrock exposures. Proximal spectral measurements and XRD analyses of samples collected from the White Dam Prospect were used to create detailed mineralogical dispersion maps of the surface and costean sections. Regolith materials of the logged sections were found to correlate with the spectrally-derived mineral dispersion profiles. The HyLogger drill core scanning instrument was used to examine the mineralogy of the fresh bedrock, which contrasted with the weathering-derived near-surface regolith materials. The overall outcomes of the thesis showed that hyperspectral techniques were useful for charactering the mineralogy of surficial materials and mapping regolith-landforms.

Abstract:
The Tertiary Mt. Skukum gold - silver epithermal vein deposit occurs 65 km southwest of Whitehorse in the Yukon Territory. Veins are hosted by a sequence of nearly flat-lying Eocene Skukum Group andesitic volcanic rocks of the Mt. Skukum Volcanic Complex, part of the Sloko Volcanic Province which unconformably overlies these intrusive complexes as well as metamorphic rocks of the Yukon Group. Major known mineralized zones occur within a regional halo of propylitic alteration centered on a fault-bounded graben within Main Cirque in the southwestern corner of the Mt. Skukum Volcanic Complex. Each zone consists of steeply-dipping quartz-carbonate-sericite veins associated with major faults and rhyolite dykes which bound blocks of the graben. Precious metals occur as electrum and native silver as fine grains averaging 15 to 20 microns and locaIly exceeding 1 mm across, in veins containing only trace amounts of sulphides. Fluid inclusions indicate that vein minerals were deposited from hydrothermal fluids averaging 313°C with an average salinity of 0.7 weight percent NaCl equivalent. Primary inclusions show that depositional fluids existed under two pressure regimes; one close to hydrostatic, the other approaching lithostatic. Both reflect depths of deposition of about 470 m below paleosurface. Variable fluid pressures reflecting similar depths of deposition combined with variable liquid to vapour ratios in primary inclusions as well as abundant textural evidence of hydrothermal brecciation indicate that boiling was common during mineralization. Oxygen and carbon isotope composition of minerals in the deposit and surrounding wall rocks indicate that depositional fluids were meteoric in origin with no contribution from magmatic sources. Large depletions in 0¹⁸ content of andesitic rocks in the deposit area indicate a minimum water rock ratio over the life of the deposit of 0.81:1. Precious metals at the Mt. Skukum deposit were emplaced at relatively low temperature in a near surface environment by a circulating, meteoric water dominated, hydrothermal system driven by a heat source associated with the rhyolite dykes. Gold, leached from andesitic volcanic rocks and metamorphic and granitic rocks was precipitated with quartz and carbonate in permeable conduits such as fault zones, and breccia bodies.

Abstract:
Detailed mapping of a 7.5 km² area at 1: 2,500 and a 1:10,000 compilation map over 60 km² have established Hazelton Group stratigraphy and structure. Hazelton Group stratigraphy begins with at least 1,000 metres of Late Triassic-Early Jurassic (210 ⁺²⁴₋₁₄ Ma; U-Pb zircon) green andesite flows, breccias and tuffs. Less than 1750 metres of green and maroon andesitic to dacitic volcaniclastic rocks overlie the andesite unit. North of Silbak Premier, at Slate Mountain, the volcaniclastic unit is overlain by up to 200 metres of a black tuff unit containing characteristic fresh biotite and white plagioclase fragments. The top of the Hazelton is a regional marker horizon, the Monitor rhyolite breccia and tuff (197 ± 14 Ma; zircon U-Pb). Hazelton volcanics are overlain by three different units. At Slate Mountain the Bowser Lake Group Bathonian/Callovian argillite and siltstone (at least 1500 m thick) lie above Hazelton rocks. Farther north on Mount Dilworth, Monitor rhyolite is succeded by black tuff or a Toarcian buff carbonate. East of Monitor Lake, less than 75 metres of Bajocian Spatsizi Group silicic shale and tuff overlies Hazelton volcanic rocks. Three intrusive episodes are discerned through isotopic dating: Early Jurassic (190 ± 2 Ma; U-Pb zircon) Texas Creek plutonic suite dacitic porphyries; Eocene Hyder suite leucocratic dykes; and oligocene-Miocene (25.2 ± 2.3 Ma; K-Ar biotite and 18 ± 6 Ma; Rb-Sr) biotite lamprophyre dykes. The Jurassic suite includes K-feldspar megacrystic "Premier porphyry" sills and dykes that are in part spatially and possibly genetically associated with mineralization. Structural features include disharmonic tight folds, ductile shear zones, and brittle faults. At least 4 phases of pre-Eocene deformation are defined by: (1) moderate west-plunging recumbent folds, (2) north-plunging inclined folds, (3) north-plunging upright folds, and (4) moderate west-plunging pencil lineations. The map area is divisible into three structural domains: the North, East and Silbak domains. The North domain is characterized by a marked structural discordance between warped Hazelton volcanic rocks and disharmonically folded Bowser Lake Group argillite and siltstone. Three phases of folding are: first phase tight to isoclinal disharmonic, recumbent folds; second phase open folds with shallow northwest-dipping axial planar cleavage; and a third phase upright, shallow north-plunging synclinorium. Structural continuity is difficult to establish due to lack of marker horizons and inferred detachments. The East domain is characterized by phase 3 gently north-northwest-plunging folds and locally east-verging asymmetric chevron folds in the Spatsizi Group. In contrast to North domain, Monitor rhyolite and/or Spatsizi Group are structurally conformable with Bowser Lake Group rxks. The Silbak domain is characterized by phase 4 pencil lineations and quartz veins. Stope geometry illustrates that mineralization occurs along two trends (1) northeast zone and (2) northwest zone of unknown phase. Steeply dipping, east-striking ductile fabrics occur in the Texas Creek batholith at the Riverside mine, Alaska and in maroon volcaniclastics along Bear River Ridge. Mylonitic fabrics at Riverside mine suggest a dextral sense of shear. A biotite lineation in the mylonitic foliation yields a totally reset Eocene K-Ar date. The width of Eocene Hyder dyke swarms indicates that there has been at least one kilometre of northeast brittle crustal extension. About 1400 metres of dextral transcurrent movement along the Long Lake-Fish Creek fault is post-Eocene dyke emplacement. oligocene-Miocene lamprophyre dykes fill fractures produced during east-west extension. Regional syntectonic greenschist grade metamorphism produced a carbonate-chlorite-sericite-pyrite mineral assemblage, probably in Middle Cretaceous time, bracketed by isotopic dating results. Hazelton Group volcanic rocks and coeval Texas Creek porphyritic rocks are subalkaline high-K to very high-K andesites and dacites. Tectonic discrimination diagrams indicate a calcalkaline, volcanic arc setting, with similar geochemical patterns to those for Andean volcanic rocks. Mineralization is hosted in Hazelton Group andesites and coeval Texas Creek porphyritic dacite sills and dykes. Mineralization and porphyry emplacement appear to have been controlled by northeast- and northwest-striking structures. Ore is predominantly discordant but locally concordant with moderately northwest-dipping andesite flows and breccias. No mineralization occurs in or above overlying maroon volcaniclastic rocks. Sericite alteration gives a Paleocene K-Ar date (63 ± 5 Ma); this is interpreted to be partially reset. The spatial link with Texas Creek K-feldspar porphyry and discordant nature of the ore suggests mineralization is Early Jurassic age and supports an epigenetic model.

Abstract:
The study area is situated in the Southern Central Zone of the intracontinental Pan-African Damara Orogen, approximately 20km NNE of Navachab Gold Mine in the Karibib district of Namibia. Mesothermal vein systems with Cu-Fe±Au mineralization are hosted by amphibolite facies calcitic and dolomitic marbles belonging to the Navachab Member of the Karibib Formation, and are best developed around the defunct Onguati Copper Mine, Brown Mountain and Western Workings areas. The Onguati study area is located in the saddle region of a moderately-to-gently inclined anticlinorium that experienced significant flattening during NNW-SSE-directed compression. The parallelogram arrangement of ENE- and NNE-trending thrusts and reverse faults that surround the Onguati study area may have developed when the direction of greatest principle subregional stress was oriented WSW-ESE. These structures define part of a Riedel shear system and later faults may have developed in the position of R and P shears respectively. Significant strain partitioning occurred between the ductile calcitic marbles which host the best developed, shear-related vein systems and the more competent dolomitic marbles. The thickness distributions of veins in the marbles of the Onguati Mine, Brown Mountain and Western Workings areas conform to a fractal or power-law distribution, The most intensely mineralized vein systems in the Onguati Mine and Western Workings calcitic marbles share similar low fractal dimensions (D-values) of 0.41 and 0.37 respectively. Veins In the calcitic and dolomitic marbles of the Brown Mountain area and in the dolomitic marbles of Western Workings have elevated D-values (>0.60) and are poorly mineralized. The low D-values «0.40) of the well mineralized vein systems reflect the higher degree of fracture connectivity. These vein systems were capable of efficiently draining and localizing large volumes of mineralizing fluids from crustal-scale structures. A metamorphic devolatization model is proposed where the entire Damaran metasedimentary and meta-volcanic package is seen as a large source area of very low concentrations of Cu, Au and other metals. Localization of deformation into crustal-scale faults and shear zones led to regional-scale hydrothermal fluid flow and focussing into the upstream fracture networks of the Onguati study area. Strong mineralization resulted when fluids encountered the reactive marble lithologies

Full text
Abstract:
While reasonable short-term resource price projections can be obtained by taking a bottom-up approach — constructing a supply curve based upon current production capacities and costs — this approach breaks down as the time horizon of the analysis lengthens. One approach to long-term price forecasting is to calibrate a simple model of a commodity market against past data. To that end, an analogy was drawn between the behavior of the uranium market and that of some three dozen materials for which the United States Geologic Survey (USGS) maintains data. This work adds to previously published results showing that the USGS-reported prices of minerals similar to uranium have consistently declined over the past century. In this paper, the extent to which uranium geology and extraction technologies are indeed analogous to other minerals is quantitatively addressed. A study of crustal abundances, ore grades being economically mined, concentration factors, market share of extraction techniques, years of proven reserve and other factors indicates that uranium is not at all exceptional with respect to the average of the USGS minerals. This suggests that, on the supply side, the analogy between the USGS minerals and uranium may indeed offer valuable insights into medium and long term uranium price behavior.

Full text
Abstract:
The aim of the article is to analyse and evaluate the information on polluted and potentially polluted places registered in the Register of polluted and potentially polluted places in Latvia. Under the influence of various natural conditions and economic activities land and soil degradation processes are observed, which has led to formation of degraded territories. Degraded territory is a territory with destroyed or damaged upper layer of ground or an abandoned territory of construction, extraction of mineral resources, economic or military activities, which in result of economic or other activity or inaction has so far destroyed, that is impossible to use it properly without special restoration measures. One of the factors that can be used to assess land degradation and determine the type of land degradation is pollution. In accordance with the Law “On pollution” in Latvia have been established procedures for identification of polluted places and developed criteria which are used for assessment of risk level. On this basis the Centre for Environment, Geology and Meteorology of Latvia has established and maintains the Register of polluted and potentially polluted places. The polluted place is soil, subsoil, water, sludge, as well as buildings, factories or other objects containing pollutants. Potentially polluted places can be listed according to unverified information. In 2017 in Latvia 351 polluted and 2648 potentially polluted places were listed and registered. The largest concentration of polluted places is located in Riga, which is largest industrial centre in Latvia.
