Hyperspectral mapping of magmatic-hydrothermal sericite, Battle Mountain mining district, Nevada

We demonstrate the utility of multi-scale imaging spectroscopy data (hyperspectral data) to differentiate magmatic-hydrothermal sericite from other white micas based on grain size, in a case study of the Battle Mountain mining district in Humboldt and Lander Counties, Nevada. The Battle Mountain mining district contains porphyry, skarn, and distal disseminated deposits that formed in magmatic-hydrothermal systems, as well as sedimentary-rock hosted gold deposits of less certain origin. We generated spectral-based mineral maps of the Battle Mountain mining district to examine the spatial distribution of spectrally dominant minerals such as kaolinite, montmorillonite, and white micas (muscovite, sericite, and illite). We then used spectral-based mineral mapping to characterize the grain size and composition of white micas, enabling us to differentiate igneous muscovite from magmatic-hydrothermal sericite. By integrating our spectral-based maps with geologic mapping, airborne aeromagnetic data, and prior studies on mines and deposits in Battle Mountain, we determined that finer grained, higher Al sericite spatially correlated with the footprints of known magmatic-hydrothermal systems and is interpreted as forming from magmatic-hydrothermal alteration. Larger grained, lower Al muscovites are distal from known magmatic-hydrothermal systems and are interpreted as being igneous derived siliciclastic sediments that became constituents of the host sedimentary rocks. Techniques described in this contribution can be applied to any appropriate hyperspectral data, regardless of sensor type used to collect the data.

Physicochemical Properties of Water Sources During the Wet Season in Enyigba and Ikwo Minig Districts of Ebonyi State, Nigeria

This study evaluated the physicochemical properties of water sources in Enyigba and Ikwo Minig Districts of Ebonyi State, Nigeria. Water samples from surface water, mine pit water, and groundwater (borehole) were collected from the mining districts, while water samples Abakaliki served as Control. Temperature, pH, electrical conductivity (EC) and total dissolved solids (TDS) were read using a water Multi meter (TK303 PLUS) while K, Mg, Na and Ca were analyzed using AAS (Agilent Clara, CA) Model 55AA. Sulphate and Phosphate were analyzed using APHA procedure while Nitrate and Carbonate were analyzed using EPA 352.1 and SAP 1999 methods respectively. The mean concentrations of physical parameters in Enyigba and Ikwo Mining Districts are Temperature (27.07 °C and 29.57°C), pH (5.70 and 5.80), EC (430.00 mg/l and 357.33 mg/l) and TDS (214.67 mg/l and 178.67 mg/l) respectively. The mean values for the Control are temperature (29.70°C), pH (6.06), EC (799.00) and TDS (396.00) respectively. Whereas the mean concentrations of cations and anions in Enyigba and Ikwo Mining Districts are K (2.98 mg/l and 4.54 mg/l), Mg (11.16 mg/l and 7.23 mg/l), Na (16.07 mg/l and13.48 mg/l), Ca (29.97 mg/l and 39.36 mg/l), Nitrate (0.32 mg/l and 0.39 mg/l), Sulphate (0.0010 mg/l and 0.0010 mg/l), Phosphate (0.0027 mg/l and 0.0023 mg/l) and Ca (0.100 mg/l and 0.15 mg/l) respectively. Whereas the mean concentrations for the Control are K (2.61 mg/l), Mg (10.63 mg/l), Na (38.30 mg/l), Ca (48.93 mg/l), Nitrate (0.0010 mg/l), Sulphate (0.0010 mg/l), Phosphate (0.0020 mg/l) respectively. From the results, the physicochemical parameters in the study area are within the threshold limits of the WHO and NESREA standards except EC for Eyingba (430) and Control (799) is higher than the WHO threshold of 400 but lower than for NESREA. The implications of these results only EC has effects on the quality of water sources at Eyingba pose health risks which require mitigation measures during the rainy season whereas the rest physicochemical parameters do not pose health risks.

Geological setting of gold-silver mineralization in the La India mining district, Nicaragua

La India gold mining district covers a 50 km² area of fault-fill gold-silver mineralized quartz-adularia veins on the western margin of a Tertiary volcanic arc in western Nicaragua. Historic mining records and modern mineral exploration data, which to-date has defined a mineral endowment of over 2.3 Moz gold, provide a wealth of geological information. This paper draws on these observations and data to describe and classify the gold-silver mineralisation at La India, identify the geological controls, and interpret the timing of mineralisation within the regional tectonic setting. The district-scale gold-silver mineralisation at La India occurs in two adjacent geological settings with distinct mineralization characteristics and exploration potential: (1) an upland area of strongly faulted felsic to andesitic volcanics where the historic mine workings are located, and (2) an adjacent downthrown graben, the Sebaco Graben, where a thick sequence of andesite is preserved overlying the felsic volcanic sequence. Gold mineralisation is classified as rift margin-type low-sulphidation epithermal gold-silver fault and fracture-fill vein mineralization. In the historic mining area erosion has exposed the top of the high-grade epithermal zone. Minimal erosion in the Sebaco Graben means that the epithermal system is fully preserved at depth, with localised hydrothermal sinter outcrops, sporadic low-grade mineralised veins and a phreatic breccia pipe exposed at surface. Apart from the one phreatic breccia, the gold-silver mineralisation occurs in quartz veins and breccias that filled brittle faults and associated fractures and fissures which developed in an extensional tectonic setting. The structures containing the gold-silver mineralisation were formed as normal and trans-tensional faults with orientations consistent with southwest-directed extension: (1) a predominant northwest to north-northwest set parallel to the subducting plate; (2) secondary but locally extensive east-west, and (3) tertiary shorter and narrower northeast and north-striking veins. A district-scale north-northwest orientated through-going structure linking the major gold-silver deposits in the historic mining area is interpreted as a deep crustal conduit for the gold-silver bearing hydrothermal fluids. Other, as yet unidentified basement feeder structures may have fed mineralised corridors in the east and west of the district. The gold-silver mineralisation is best developed where structures pass through competent felsic volcanics and welded tuffs in the historic mine area, and also in the overlying andesite flows in the Sebaco Graben. Gold-silver mineralisation is less well developed where the structure passes through less competent unwelded tuffs and volcanic agglomerates. Gold-silver mineralisation is interpreted as occurring shortly before or at 8-10 Ma at the end of a long period of slab-rollback induced extension and arc volcanism. Post-mineralisation block faulting split the La India district into the upthrown, and subsequently eroded historic mine area where epithermal mineralisation is largely exposed at surface, and the well-preserved downthrown blocks such as the Sebaco graben where much of the gold-silver mineralisation is still hidden several hundred metres below surface.

U–Pb Geochronology of the Baguio Area, a Major Mining District in Northern Luzon (Philippines)

ABSTRACTThe Baguio District, located in northern Luzon (the Philippines), is one of the major gold and copper mining districts in the Philippines and SE Asia. U–Pb zircon ages for igneous rocks and for detrital zircons extracted from sediment samples of the principal formations of the Baguio District reveal major magmatic pulses at ca. 1, 3, 16, and 20 Ma. The oldest zircon dated in this study has an age of 27.3 ± 1.6 (2σ) indicating earlier activity which has, however, left only a small imprint on the zircon inventory of the sediments. The absence of older zircons suggests that northern Luzon formed as an intra‐oceanic arc. Zircon Hf isotope data suggests that the magmas, from which the zircons crystallized, were derived from time‐integrated highly depleted mantle sources, compatible with an intra‐oceanic origin of the island. The results of the U–Pb dating of zircons mostly confirm previous estimates of the ages of the rock units. Mid‐Miocene ages obtained for samples thought to represent the Pugo Formation, the lowermost unit, which is thought to be Cretaceous‐Eocene in age, most likely date magmatic rocks that intruded the Pugo Formation.

Economic effect of modification the optimal contour of the Open Pit South Mining District Majdanpek, Republic of Serbia

The Open Pit South Mining District is a unique unit that operates within the company Copper Mine Majdanpek, which is a part of the company Serbia Zijin Copper doo (former Mining and Smelting Basin Bor Group). The capacity of the Open Pit is 9.9 million tons per year and is of a great importance for copper production in the company system. As a result of natural and technical factors, a landslide occurred on the Eastern side of the open pit, so it became necessary to define a new final contour of the open pit. In this paper, the effect of modification the optimal contour of the Open Pit South Mining District on the net present value (NPV) was analyzed.

Interpretation of Regional Geophysical Data Acquired at the Bathurst Mining Camp, Canada

The Bathurst Mining Camp is a major base-metal mining district in New Brunswick, Canada that was a focus area for the Geological Survey of Canada Targeted Geoscience Initiative Phase 3 project. As part of this project, more than 3500 gravimetric observations were acquired in the Bathurst Mining Camp, with an average spacing of 1-2 km, in 2006. The gravimetric data was reduced for an average crustal density value of 2.77 g/cm3 to obtain the Bouguer anomaly, which was analyzed and used to obtain 2.5D gravity models along five transects crossing the Bathurst Mining Camp. As a result of gravity modeling, a model of the general geometry of the main geological groups of the Bathurst Mining Camp (Fournier, California Lake, Tetagouche, and Miramichi) was obtained, which suggests that the Nine Mile Syncline is an open fold, and the Tetagouche Anticline is a gentle fold. Both folds are non-cylindrical and inclined, with their axial planes dipping in the 293° N direction: the angle of vergence of the folds increases towards the northeast of their axes. The structures under the Tetagouche Anticline axis gradually get deeper towards the Northeast reaching a maximum depth of 4 km. The depth of the structures modeled under the axis of the Nine Mile Syncline varies between 2 and 9 km, the deepest part being towards the center of the Bathurst Mining Camp; towards the northeast of its axis, the structures reach an intermediate depth of 4 km while towards the southwest they are 2 km deep on average.

Nano-mineral assemblages in mercury- and silver-contaminated soils: records of sequestration, transformation, and release of mercury- and silver-bearing nanoparticles.

Mercury-bearing nano-mineral assemblages (Hg-NMAs) are chemically and mineralogically heterogeneous, micrometer-sized aggregates of nanoparticles (NPs) found in contaminated soils and sediments. Although these NMAs control sequestration and release of Hg that is a global contaminant, our understanding is limited with respect to the conditions of different types of Hg-NMAs, the diversity of its minerals, the size distribution of its NPs and whether mineral replacement and alteration reactions in these NMAs result in the release of Hg-bearing NPs. For this purpose, Hg-NMAs in four sediment samples from the Guanajuato Mining District (GMD) in Mexico, a region that was polluted by Hg and silver (Ag) due to historical mining involving Hg amalgamation, are characterized at the micro- and nanoscale. Microscale examinations with SEM show that the majority of Hg-NMAs occurs in mineral surface coatings (MSC) and fillings in fractures within quartz grains and are enriched in Hg and sulfur (S) relative to Ag, and in S and selenium (Se) relative to chloride (Cl). Examinations at the nanoscale show that Hg-NMAs contain (a) residuals of the patio process such as amalgam phases and elemental Ag; (b) associations of Hg- and Ag-sulfide NPs with pyrite and marcasite; (c) associations of Hg- and Ag-sulfide NPs with goethite and clay minerals along the rims of the MSC. The latter minerals replaced the Fe-Si-rich matrix at high-water rock ratios most likely due to an increase in porosity during flooding of the Pastita River. Consequently, the rims are depleted in Hg-Ag-sulfide NPs relative to the unaltered Fe-Si-rich matrices indicating that changes in the physiochemical conditions of soils and sediments in the GMD can result in the release of Hg-Ag-bearing NPs. In this context, this study discusses whether release and dissolution of Hg-Ag-bearing NPs contribute to the recently observed elevated gaseous elemental Hg concentrations in the soil, interstitial air and ambient air, and to the fate and effects of Hg in local aquatic environments.

Natrochalcite NaCu2(SO4)2∙H3O2 from the Lavrion Mining District – a brief characterisation

Abstract Recently, samples of natrochalcite, NaCu2(SO4)2∙H3O2, were discovered from the Esperanza Mine, Lavrion Mining District, Greece. In the present study this material is characterized by single crystal X-ray diffraction at ambient and LT conditions. Natrochalcite is monoclinic, space group C2/m, with a = 8.809(2), b = 6.196(1), c = 7.504(2) Å, β = 118.56(3)°, V = 359.7(1) Å3, Z = 2, R1 = 0.0195 at room temperature. No symmetry change was observed down to 100K.

Preliminary discussion on pyrrhotite, gold killer in Wells-Barkerville, British Columbia, Canada

The Wells-Barkerville area of the Cariboo gold mining district is situated within the Quesnel Highlands on the eastern edge of the Interior Plateau in central British Columbia, Canada of the eastern Circum-Pacific volcanicmetallogenic belt. Recorded gold production from the area totals more than 4.0 million ounces, including an estimated 2.7 million ounces from placer mining from 101 creeks and 1.3 million ounces from lode mining. There are five principal types of lode gold deposits in the district; namely, auriferous pyrite replacement, including replacement in limestone and that in calcareous clastic rock; pyrite-quartz vein/veinlet lode gold, including strike vein, diagonal vein, orthogonal vein, and quartz veinlets; basalt-hosted auriferous pyrrhotite-pyrite lode gold; and associated gold in porphyry copper styles. This area is historically a famous gold production area in western Canada, including the initial alluvial gold and later and current lode gold. This original short article uses drilling results to illustrate that pyrrhotite in this area is the killer of gold. Wherever there is pyrrhotite, the gold grade is very poor or even contains no gold. In other words, gold grade is inversely related to pyrrhotite content. Then, the spatial distribution characteristics of the pyrrhotite anomaly zone(s) existing in this area were summarized, including the approximate thickness of zone(s). On this basis, several deep drill holes are recommended to verify whether there is considerable gold mineralization beneath the pyrrhotite anomaly zone(s).

Ring-shape and linear gold mining districts of zimbabwe: estimation of residual gold resources

Background. Despite the long history of exploitation and study of Zimbabwe’s geological potential, the ranks of gold ore formations at the level of regions and fields remain unclear. Assessment of the residual primary gold deposits in Zimbabwe appears an important research direction.Aim. Identification of ring-shaped and linear ore districts confined to greenstone belts corresponding in configuration within the gold province of the Zimbabwe craton.Materials and methods. The main method for analyzing gold ore deposits was ore formation analysis. To analyze the residual gold resources in the regions of Zimbabwe, the Zipf-Lotke-Bradford rule was applied according to the ratio of an outstanding rare event in the form of a large deposit, rather rare events in the form of medium-sized deposits, and fairly rare events in the form of small ore objects in a certain ore region.Results. A hypothesis is proposed for the formation of ring-shaped belts as ore-bearing volcano-tectonic structures of the central type. Within the gold province of the Zimbabwe craton, ore districts of ring-shaped and linear shape, confined to greenstone belts corresponding in configuration, are identified for the first time. It is shown that the localization of deposits in ore regions is due to a combination of the following criteria: ancient faults, arc fragments of greenstone belts, and the development of post-tectonic multiphase granitoid magmatism. A ranking of deposits was carried out in the ore districts of Darwin, Shamva, Midlands, Bulawayo, Gwanda, Busha Mwezi - Fort Victoria, Shashe - Ozi-Umatli, and Sinoia. Five gold mining areas corresponding to volcano-plutonic ring-shape structures and three linear areas were identified. Productivity is predicted to be highest in the Midlands, Bulawayo, and Shamva ring-shape regions. An assessment of the residual gold resources of each of the selected areas is given. The feasibility of detailing important forecast criteria — Late Archean linear and arc faults and post-tectonic granitoids — with the development of additional criteria for further metallogenic zoning and localization of promising areas is established.Conclusions. The presented data serve as the basis for assessing the prospects of industrially important primary gold deposits in Zimbabwe and carrying out their forecast in the identified gold mining areas.

Prospects of the Bug mining district as an agglomeration of ore and non-ore mineral deposits for the reconstruction of the national economy of Ukraine in the post-war period

The role and capabilities of Ukrainian geological science, production and investment capital in the reconstruction of the national economy of Ukraine during the war and post-war period are considered here using the example of the Bug mining district (BMD) of the Ukrainian Shield (USh).
 BMD is characterized by an extremely wide range of deposits and ore of minerals relatively close to the surface, among which the most important ones are graphite, iron ore and iron-manganese, nickel-chromium-cobalt deposits, deposits and ore occurrences of gold discovered by geologists and geophysicists for many years. Numerous deposits of building materials and kaolin are also known here. There are prospects for obtaining local agrochemical raw materials based on the development of apatite-containing ores and calcifers.
 The article lists and shows the location of mineral deposits and ore occurrences which arethe most well-prepared for industrial development and investments. The composition of ores and the content of useful substances are given for some of them.
 Two powerful industrial enterprises are located on the BMD square, i.e., the Zavallye graphite factory and the Bug ferronickel plant (currently repurposed for other products). They can be used to process the above-mentioned ore raw materials, with some improvement of technological processes. In this regard, the possibility and practicality of creating two centers (clusters) of integrated mining and industrial development of these useful resources were considered. One of them can be created on the basis of nickel-cobalt and iron ore deposits of BMD with an orientation towards the Bug ferronickel plant. The second center can be created based on the enrichment of iron-manganese oxide ores using the technical capabilities of the Zavallye graphite plant.
 In case of realization of the entire economic potential of the industrial development of graphite ores of the region, Ukraine could become a world leader in this field and receive significant funds to reconstruct the industry disrupted by the war.
 The BMD also meets all the geological and economic prerequisites to become the first region on the Ukrainian Shield for industrial gold mining.

Volcanic Domes Associated with Au-Ag (Pb-Zn) Mineralization in the Shila-Paula Mining District: Arequipa - Peru

The objective of the present study is to promote the exploration of volcanic domes of rhyolitic to dacitic composition associated with Au-Ag (Pb-Zn) mineralization, mainly where there is little evidence of structures and especially where they do not report significant grades in gold, silver, lead or zinc; except in volatile elements, trace elements and rare earths, where it is often not given due importance.
 The main lineaments of the Shila-Paula mining district are of an Andean NW-SE strike that generate E-W orientation tensions, with this system being the main one because it hosts known economic mineralization in the mining district. In addition, the important mineralized domes in the Shila-Paula mining district are related to hydrothermal alteration of the High Sulphidation (HS) type, with sub-outcropping structures of quartz-alunite composition, grading to argillic and finally distal to propylitic.

From Galena to Lead: Divergent Paths in Early Metallurgy in the Western Mediterranean

This paper examines the use of galena, beginning in the Middle Paleolithic, before the onset of metallurgy in the Iberian Peninsula, and shows that it was a well-known raw material during the Neolithic, both in funeral and in household contexts. The identification of probable provenance suggests a non-long distance movement, with the Molar-Bellmunt-Falset mining district in Tarragona as the main source area for extracting this ore since the Palaeolithic. Although southern France and other European regions share a similar use of galena in Neolithic times, each took different approaches to the use of the raw material. In some areas (southern France, Sardinia) lead was used for metal production, while in others (Iberia, continental Italy) it was not. These differences can be explained by different social choices in each region, reinforcing the idea that innovation is not simply a question of technology.

Sulphide petrology and ore genesis of the stratabound Sheep Creek sediment-hosted Zn–Pb–Ag–Sn prospect, and U–Pb zircon constraints on the timing of magmatism in the northern Alaska Range

The Sheep Creek prospect is a stratabound Zn–Pb–Ag–Sn massive sulfide occurrence in the Bonnifield mining district, northern Alaska Range. The prospect is within a quartz–sericite–graphite–chlorite schist unit associated with Devonian carbonaceous and siliceous metasedimentary rocks. Volcanogenic massive sulfide (VMS) deposits in the district are hosted in felsic metavolcanic rocks (362 ± 2 Ma) associated with siliciclastic and carbonaceous sedimentary rocks that overlie the stratigraphic sequence hosting the Sheep Creek prospect. Felsic metaigneous rocks in underlying units are 372 ± 4 to 366 ± 4 Ma. Sheep Creek is atypical of the other sulfide deposits in the district in (1) having Sn grades up to 1.2%; (2) being contained in fine-grained, quartz-rich rocks and quartz–pebble conglomerate that likely originated as chert and chert-clast sediment, respectively; and (3) showing minimal evidence of volcanic components in the host rocks. Comparison of immobile trace-element proportions for graphitic and siliceous rocks from the Sheep Creek area with those for argillite associated with the Bonnifield VMS deposits indicates a continental volcanic-arc provenance for the former and a within-plate and passive margin provenance for the latter. In contrast to previously published interpretations, our data analysis supports a clastic-dominated (CD) rather than a VMS affinity for the Sheep Creek prospect. In our model, Zn–Pb–Ag–Sn mineralization formed by syngenetic or early diagenetic processes on or beneath the seafloor, possibly in the shallow-water environment of an outer continental shelf setting. Potential analogues are the Paleozoic CD deposits in the Canadian Selwyn Basin outboard of the Laurentian continental margin.

Deep Structure of Nanling-Xuancheng Ore District, Eastern China: Insights from Integrated Geophysical Exploration

As the depth of mineral exploration increases, integrated geophysical methods are increasingly playing a crucial role in prospecting deep structures at the district scale. The Nanling-Xuancheng ore district is the eighth ore district in the middle-lower Yangtze metallogenic belt in China. To reveal the deep structure of the mining district, this study mainly focuses on regional high-precision gravity and magnetic data and integrates the interpretation of magnetotelluric and reflection seismic data from a key area. By using a 2.5D joint inversion method with prior information constraints, new insights into the deep structures, tectonic deformation, and magmatic activity are obtained. Structurally, the Nanling-Xuancheng ore district presents a structural pattern of “two uplifts and two depressions” composed of multi-level thrust-overturned and folds formed by Mesozoic depressions, which has a three-layer structure in the vertical direction (shallower than 10 km). Tectonically, the main faults in the study area trend NW, which intersect with NE-trending and EW-trending faults to form a branching structure from deep to shallow. The fault intersections provide pathways for magma intrusion. The distribution of deep-seated concealed magmatic rocks shows the characteristic pattern of “a primary magma source spawning multiple subsidiary intrusion”.

Silver, cobalt and nickel mineralogy and geochemistry of shale ore in the sediment-hosted stratiform Nowa Sól copper–silver deposit, SW Poland

The Nowa Sól deposit is a part of the newly discovered Northern Copper Belt and is situated some 30 km NW of the Lubin–Sieroszowice mining district (the so-called New Copper District) in SW Poland. The ore horizon spans across the upper part of the Lower Permian (Rotliegend) terrestrial redbeds and the lower part of the Upper Permian (Zechstein) marine rocks. It comprises three lithotypes: sandstone, shale and carbonate. The high-grade shale ore has polymetallic characteristics and is a crucial host for by-product metals such as Ag, Co and Ni (studied in this paper), but also Mo, V and Re. The results of bulk-rock and electron microprobe as well as mineralogical (optical and scanning electron microscope) data of the mineralized, organic-rich shale ore from the Nowa Sól deposit are presented. This thin stratigraphic horizon, ranging from 0.06 to 0.59 m, shows notable concentrations of critical metals, including on average 15.9 wt% Cu, 715 grams per tonne (g t -1 ) Ag, 318 g t -1 Co and 345 g t -1 Ni. It constitutes less than 10% of the total ore mass, but accounts for 36% of the Ag, 40% of the Ni and 42% of the Co found within the deposit. The ore sulfides in the mineralized shale in the Nowa Sól deposit include chalcocite, djurleite and bornite, accompanied by digenite, covellite, tennantite, galena, sphalerite and pyrite. The Ag content within the Cu sulfides exhibits a linear decrease: chalcocite > djurleite > bornite. Three primary Ag minerals are identified within the shale ore, namely native Ag, Ag amalgam and stromeyerite. Two types of Ag amalgam are observed: Hg-rich and Hg-poor. Cobaltite and gersdorffite represent the primary Co and Ni minerals, occurring as micrometre-sized inclusions within chalcocite and djurleite. Textural observations suggest that the Ag, Co and Ni mineralization postdates the major phase of Cu sulfide precipitation. It is shown that in the Nowa Sól deposit, the Kupferschiefer horizon has acted as a geochemical barrier for the above-mentioned metals during protracted time, from early syndepositional to late epigenetic stage of basin evolution.
