Full textAbstract:
Silver is one of the rarest metals in nature and certainly among the most used ones, not only as precious good for financial investments but also for many industrial critical applications. Because it would be very difficult to analyze the situation regarding the future global availability of silver as a commodity in general, due to the necessity of a large amount of data which are hardly available, we have focused only on the mining production of primary silver. In particular, the study regards the activities of a sample consisting of twelve of the world top fifteen leading primary silver mines, which represent the 54% of the worldwide primary silver production and 16% of the global silver mining production. We have investigated the related exploitation state and trends of these twelve sites by elaborating their last ten-years statistics on silver production, ore grades, resources and reserves. The findings of this study, in short, are that the cumulative average silver ore grades, both in extracted mineral, resources and reserves, of the above selected mines, have decreased and also that the new mining fields (Dukat, San Bartolomé, Pirquitas, Saucito) have lower silver content indexes than the older ones.

AbstractThe present article shows that, according to archaeological and literary evidence, an expansion in mining occurred in the early Islamic world as a result of changes in mining technology at the end of Late Antiquity. The production of gold, silver, copper, iron, and other minerals is shown to have peaked in the eighth and ninth centuries and then to have declined during the tenth and eleventh centuries due to insecurity and/or exhaustion of the mines. Mining development was financed privately, and mines were usually private property.

Full textAbstract:
Subsidence at abandoned mines sometimes causes destruction of local areas and casualties. This paper proposes a mine subsidence risk index and establishes a subsidence risk grade based on two separate analyses of A and B to predict the occurrence of subsidence at an abandoned mine. For the analyses, 227 locations were ultimately selected at 15 abandoned coal mines and 22 abandoned mines of other types (i.e., gold, silver, and metal mines). Analysis A predicts whether subsidence is likely using an artificial neural network. Analysis B assesses a mine subsidence risk index that indicates the extent of risk of subsidence. Results of both analyses are utilized to assign a subsidence risk grade to each ground location investigated. To check the model’s reliability, a new dataset of 22 locations was selected from five other abandoned mines; the subsidence risk grade results were compared with those of the actual ground conditions. The resulting correct prediction percentage for 13 subsidence locations of the abandoned mines was 83–86%. To improve reliability of the subsidence risk, much more subsidence data with greater variations in ground conditions is required, and various types of analyses by numerical and empirical approaches, etc. need to be combined.

AbstractThis article explores mining as the motor of temporary and permanent migration into the Far Southwest of Ming and Qing China. It focuses on the workforce of borderland silver mines, specifically on travel routes and the geography of recruitment. Durations and costs of the journeys reflect the existence of efficiently organized networks. The men who set out for the mines did so in the expectation of making money and returning home with handsome gains. This provides insights into the sizeable and profitable non-agrarian sector in the late imperial economy.

This study found evidence which supports the thesis that cost accounting techniques evolved rapidly during the last quarter of the nineteenth century. The cost accounting system employed by the leading mines of the Comstock Lode during the 1870's is compared to a system used in the Cripple Creek district of Colorado during the first decade of the twentieth century. The cost accounting techniques of the mining industry appear to have developed rapidly during this period from crude to sophisticated systems.

Abstract A donation stele discovered in the 1980 records that the community of the Fulong silver mines raised some 4500 liang of silver to build a temple dedicated to the God of Wealth in 1814. The site in a remote mountain range in northern Yunnan evidently was a prosperous and populous mining town. Yet it appears in no government record. Centered on the case study, this paper provides insights into social self-organization of communities and the structures within the Qing government that allowed the operation of mines that were registered with the local governments and submitted taxes yet kept out of the communications with the central government. The analysis contributes a specific example of communal governance structures and explains the two layers in late imperial administration, one which was official and documented in gazetteers and central records, and another which was customary and usually undocumented.

Abstract The Archaeological Mines Park of San Silvestro is part of the Campiglia mining area. It represents its most important historical core. The Park covers a surface of around 450 hectares on the mountains Calvi, Rombolo, Poggio all’Aione and along the valleys Temperino, Lanzi and Manienti. The main characteristic of the Park is the richness of mining activity traces towards copper, lead and silver. The mining activity started during the 7th century BC with the Etruscan civilization and continued until 1979, when the last mine was closed. Many karst cavities of the Campiglia are “cave-mines’: they are the result of a natural event and the action of ancient miners, who searched metalliferous minerals. In Campiglia there are traces of hundreds of Etruscan, medieval and modern mining operations, tunnels from the 19th and 20th centuries. The aim of the Archaeological and Mining park of San Silvestro is to highlight historical landscape, the result of centuries of mining activities. Some of the buildings, originally used for productive and administrative purposes, have been restored to house exhibitions and services for visitors. The impressive ruins of the medieval village of San Silvestro and two of the modern mining tunnels, have been equipped for guided tours. The accessibility of ancient mining works is however still difficult and this represents a limit in the enhancement and protection of these sites. Speleologists, archaeologists and geologists will be involved in making a project to let everyone discover the most ancient underground mines. We have three main targets: (1) produce high quality pictures of the most interesting and impressive mining traces; (2) create 3D models useful for scientific and cultural purposes; (3) equip some of the ancient shafts with light structures to allow small groups to visit them. We will describe the morphological characteristics of one of these ancient mines, giving some advice for the production of high quality picture in this contest. We will also describe the technique used for the production of a 3D model and how to equip the mine for the visit of small groups of people.

Full textAbstract:
The article examines strategies of harnessing mineral resources for community empowerment, poverty reduction and infrastructure development in mining areas of Zimbabwe. Despite abundant mineral resources, the majority of Zimbabwean indigenous communities living close to the mines have limited access to directly or indirectly benefit from the mineral resources. Using a descriptive survey to collect data, this research article gives a strong proposition on how the Indigenisation and Economic Empowerment Act can be used as a vehicle of harnessing mineral resources. The article argues that pro poor mining policies that ensure the harnessing of mineral resources for community empowerment, poverty reduction and infrastructure development are paramount. The article further argues that the Indigenous and Economic Empowerment Act needs to be harmonised with other sector legislation in the country. The article concludes that the development of infrastructure and provision of public utilities such as electricity, water, establishing micro-credit to small and medium enterprises and implementing broad-based indigenisation policies are some of the strategies of improving rural livelihoods. Similarly direct and indirect linkages between the mining sector and local economy could be enhanced through the provision of food supply to the mine, manufacture of mining inputs, provision of security services and supply of labour by the local community. The article recommends that the harmonisation of legislation that has an effect on harnessing of mineral resources by local communities will ensure community empowerment, poverty reduction and infrastructure development.

Full textAbstract:
AbstractUnderground mining in Potosí was a male sphere. Nevertheless, women were actively involved in the early stages of silver mining in Potosí, when traditional technologies were still in use. They also played an important role in the local ore market. After the introduction of new technology and the reorganization of the labour force, the process of refining ore was much more complicated. Women then participated in some stages of the process: in selecting the ores and sieving. This implies that mining is a complex process with a labour and gender division that has been underrated and underestimated. More importantly, women became owners of rudimentary mills (trapiches) where the ore was processed, selling different amounts of silver to the Spanish authorities, making their living in this way.

Full textAbstract:
Structural geology, groundwater, shear strength and blasting control pitwall stability at Equity Silver Mines, Houston, British Columbia. A geotechnical investigation of, these parameters was carried out in the Main Zone pit during the summer of 1984. The objective of the study was to develop a pitwall design based on geologic and groundwater conditions observed in each design sector. This thesis presents the results of the investigation; methods of improving stability by drainage and control blasting are also discussed.
Information on structural geology was obtained by line mapping of existing berms. The discodat package of computer programs was used to process the structural data and to identify trends in orientation of discontinuities. Based on this information, the Main Zone pit was divided into ten design sectors, each sector having a consistent pattern of discontinuity orientations, rock type, groundwater conditions and pit wall orientation.
Kinematically possible failure modes were identified in each design sector. Failure modes that were expected to present stability problems were analyzed to calculate factor of safety. Pit wall and berm face angles were then selected such that only a small number of potential failure modes will daylight.
The stability evaluation has shown that it should be possible to increase pitwall angles by 5〫 in the west half of the pit. However, the data base in this area of the pit is presently limited because only a small number of berms are exposed. Therefore, additional line mapping will be required before the west wall design can be finalized. Groundwater will reduce pitwall stability, especially in the east half of the Main Zone pit. Multi-berm failures are very sensitive to groundwater conditions. A dewatering system should be installed in the Main Zone pit to minimize the possibility of such failures occuring.
Wet blastholes dictate that expensive water resistant slurry explosives be used in many areas of the Main Zone pit. The dewatering system should also draw down the water table so blastholes will become dryer and less expensive ANFO can be utilized.
The magnitude of shear strength on failure surfaces is required in order to evaluate stability of potential failures. Slip tests, point load tests and back analyses of existing failures were used to determine the shear strength parameters. Further studies should be carried out to better define the parameters at higher stress levels that will develop in a multi-berm failure.
Further potential for pit steepening exists if the berm face in the volcanics can be maintained at a slightly steeper angle, e.g. 70 instead of the present 66°. It may be possible to achieve this goal if trim blasting procedures are modified to reduce blast damage to the final wall.Applied Science, Faculty of

Full textAbstract:
Gold exploration was conducted in northern margin, granulite-facies rocks of the Limpopo Belt. Methods used in the prospecting include drainage, soil and rock geochemistry, geophysical surveys, geological mapping, trenching and diamond drilling. These techniques successfully led to the discovery of two medium size, mesothermal gold deposits (Grid 2s and Grid 4). Objectives of this study were to (a) document the exploration methodology used; (b) describe the regional geology; (c) establish a mineral deposit model; (d) outline the methods and results of various exploration techniques; (e) outline follow-up procedures and evaluation of anomalies; and (f) discuss results of the exploration exercise and conclusions. The granulite-facies terrain comprises Charno-enderbites, mafic and felsic to intermediate metavolcanic rocks and meta-sediments. Renco Mine situated immediately east of the study area, was selected as the ore deposit model for the exploration program. Gold mineralization occurs in shear and thrust zones within an enderbite. The gold deposits are structurally controlled by a first-order, Sinistral transcrustal Mauch Shear Zone, which is parallel to a regional east-northeast penetrative foliation. The deposits are in dilation zones where the Mauch Shear (a) is intersected by a dextral east-west shear (Grid 2s), or (b) has a sinistral splay (Grid 4 and Renco). Close to these deposits, the Mauch Shear is in contact with a "greenstone belt", which is a possible source of crustal metamorphic ore fluids and gold. The Grid 2s deposit contains fine-grained, disseminated free gold, and small amounts of pyrrhotite, pyrite and chalcopyrite in quartz veins within third-order shears in K-feldspar granite. K-feldspar, sericitic, silicic, sulphidation and carbonate alteration characterizes the deposit, which has a proposed mantle-degassing model. The Grid 4 deposit is magmatic porphyry-type, with CuMo and Au in third- and fourth-order shears respectively. Mineralization comprises disseminated to semi-massive pyrrhotite, pyrite, chalcopyrite, sphalerite, bismuth, molybdenite and gold. Wall rock alteration includes biotitic, chloritic, silicic, sulphidation and carbonate. In Grid 2s, Grid 4 and Renco deposits, the alteration mineral assemblages are in three facies, which are granulite, amphibolte and greenschist. In the three deposits, the mineralization occurs with the amphibolite-facies, indicating post-peak, retrograde metamorphic conditions.Illustrations (maps) only available in print form at Cory Library

Thesis (MPA)--Stellenbosch University, 2014.ENGLISH ABSTRACT: The aim of this research was to investigate the challenges to effective strategy implementation at the Zimbabwe Mining Development Corporation (ZMDC). Strategic planning is argued to have overshadowed the area of actual strategic implementation. Organisations put a lot of effort into drafting good plans, but do not put equal effort into their realisation. It was assumed that there is a big gap between strategic planning and implementation. This is what drove the researcher to go into the field and explore the situation at the ZMDC in greater depth in a bid to bridge the gap through research on the subject matter. Literature on strategy and strategy implementation was analysed critically. The research was guided by the post-positivism research philosophy. This research paradigm enabled the use of qualitative methods, which facilitated the interaction with respondents. The case study research design was adopted, as the research sought to discover the impediments to strategy implementation and the best way forward in turning the strategies on paper into action. The major findings were that there indeed were loopholes in strategy implementation at the ZMDC. The challenges to the strategy implementation process at the ZMDC were noted to be poor delegation, lack of training and development, poor ethical values, limited resources, low motivation of employees, poor communication and coordination, lack of control and poor teamwork. The organisation was noted to have deficient communication processes, which contributed to the challenges facing strategy implementation. The findings brought to light the fact that strategic planning starts with the executive management, hence the need for their commitment to owning the entire process of strategic planning and execution. The study revealed limited involvement of staff in the initial stages of developing strategy. In order to enhance the implementation of strategies, it was recommended that motivational leadership at the ZMDC had to be ensured. Leadership, ownership and drive are required to compete effectively and to deliver growth. Management should adopt the „Strategy into Action‟ planning approach, charting a course through performance factors, linking strategic thrusts to projects, as well as departmental and individual activity, with the ultimate goal being to enable the ZMDC to effectively translate strategic goals into results in a clear and inclusive process. To turn strategic desires into action that drives results, the ZMDC leaders need to develop strategic thrusts and broad-based action plans, putting the vision to light, and picturing to everyone what would be viewed as strategic success and what it takes to achieve and measure the desired outcomes.
AFRIKAANSE OPSOMMING: Die doel van hierdie navorsing was om ondersoek in te stel na die uitdagings vir doeltreffende strategie-implementering by die Zimbabwe Mining Development Corporation (ZMDC). Daar word aangevoer dat strategiese beplanning wesenlike strategiese implementering oorskadu. Organisasies werk hard aan die opstel van goeie planne, maar werk nie ewe hard aan die verwesenliking daarvan nie. Die aanname is gemaak dat daar ʼn groot gaping tussen strategiese beplanning en implementering is. Dit het die navorser aangemoedig om die situasie by ZMDC prakties en op diepgaande wyse te ondersoek ten einde hierdie gaping deur navorsing oor die onderwerp te oorbrug. Die literatuur oor strategie en strategie-implementering is krities ontleed. Die navorsing is gerig deur ʼn post-positivisme-navorsingsfilosofie. Hierdie navorsingsparadigma het die gebruik van kwalitatiewe metodes moontlik gemaak, wat interaksie met die respondente in die hand gewerk het. ʼn Gevallestudie-navorsingsontwerp is gebruik, aangesien die doel van die navorsing was om die struikelblokke tot strategie-implementering en die beste pad vorentoe om strategie op papier in aksie oor te skakel, te bepaal. Die vernaamste bevindings was dat daar wel skuiwergate in strategie-implementering by ZMDC is. Die uitdagings rakende die strategie-implementeringsproses by ZMDC is geïdentifiseer as swak delegering, gebrek aan opleiding en ontwikkeling, swak etiese waardes, beperkte hulpbronne, lae motivering van werknemers, swak kommunikasie en koördinering, gebrek aan beheer en swak spanwerk. Daar is gemerk dat die organisasie gebrekkige kommunikasieprosesse het, wat tot die uitdagings vir strategie-implementering bydra. Die bevindings het aan die lig gebring dat strategiese beplanning by die uitvoerende bestuur begin, en dus is hul toewyding tot eienaarskap van die algehele strategiese beplannings- en uitvoeringsproses noodsaaklik. Die studie het beperkte betrokkenheid van personeel by die aanvanklike fases van strategie-ontwikkeling getoon. Ten einde die implementering van strategieë te bevorder, is die aanbeveling om motiveringsleierskap by ZMDC te verseker. Leierskap, eienaarskap en dryfkrag is nodig om doeltreffend mee te ding en te groei. Die bestuur moet die beplanningsbenadering van „Strategie in Aksie‟ aanneem, wat die weg deur prestasiefaktore aantoon en strategiese dryfkragte aan projekte asook aan departementele en individuele aktiwiteit koppel. Die uiteindelike doelwit is om ZMDC in staat te stel om strategiese doelwitte doeltreffend in ʼn duidelike en insluitende proses in resultate om te skakel. Ten einde strategiese strewes in aksie wat resultate lewer om te skakel, moet ZMDC se leiers strategiese dryfkragte en breedgebaseerde aksieplanne ontwikkel, waardeur die visie duidelik gemaak word en almal duidelikheid het oor wat as strategiese sukses beskou word en wat dit verg om die gewenste uitkomste te bereik en te meet.

Full textAbstract:
The San Dimas mining district, including the Tayoltita mine, is a Tertiary silver-gold epithermal vein system deposited in a calcalkaline volcanic pile. Hydrothermal alteration and vein formation is temporally related to a granite batholith intruded into the volcanics. Alteration mineralogy in andesites is compatible with a hydrothermal flow model in which heated water rises through the batholith, cools to 260°C, and flows out into the volcanics. In the process, a(Na)⁺/a(H)⁺, a(K)⁺/a(H)⁺, a(Ca)⁺⁺/a²(H)⁺, a(SO₄)⁼.a²(H)⁺, and a(H₂S) increase; a(A1)⁺⁺⁺/a³(H)⁺ decreases; and a(Fe)⁺⁺/a² (H)⁺ remains constant, all relative to original fluid conditions in the andesites. Lateral elongation of Ag:Au ratio zoning plotted on vertical projections of veins is interpreted to reflect hydrothermal fluid flow principally in a horizontal direction during ore deposition. Quartz vein-filling, accompanied by chlorite, calcite, rhodonite, and adularia, is widest in a vertical interval approximately 500 to 1,000 meters below the original surface. Pyrite is widely distributed, but silver minerals, electrum, and base-metal sulfides are restricted to the upper portion of the vertical interval of veining in a zone termed the ore horizon. Paragenetic relationships among vein minerals of the Cinco Senores vein in the Tayoltita mine indicate that a(H₂S) decreased; a(Cu)⁺/a(H)⁺, a(Ag)⁺/a(H)⁺, and a(Au)⁺/a(H)⁺ increased; and a(Fe)⁺⁺/a²(H)⁺ and a(SO₄)⁼.a²(H)⁺ remained nearly constant during the initial stage of ore deposition. Fluid inclusion studies of quartz from the Cinco Senores vein indicate that ore deposited at an average temperature of 260°C from boiling fluids of apparent salinities ranging from 0.15 to 0.3 m(NaCl) equivalent. The greater apparent salinities probably reflect dissolved gases as well as chloride salts. Correlation of Ag:Au ratios in deposited vein with ice-melting temperatures in fluid inclusions suggests that evolution of ore fluids in space was accompanied by both increase in deposited Ag:Au ratios and decline in fluid solute concentration. Correlation of ice-melting temperatures with paragenetic age of associated quartz suggests that vein-depositing hydrothermal fluids evolved in both space and time from relatively concentrated to dilute conditions. Both boiling and mixing could have caused this decline in solute concentration.

A mitjan segle XIV, es va potenciar l’explotació minera de l’argent al comtat de les Muntanyes de Prades i baronia d’Entença. Aquest domini comtal, creat l’any 1324, conformava un conjunt territorial i senyorial indivisible sota la regència d’un únic senyor. En aquest marc ampli, l’explotació del metall noble es va desenvolupar especialment al voltant de la ciutat que exercia la capitalitat administrativa del domini: Falset (el Priorat, Catalunya). De fet, hi va haver un boom de l’explotació d’argent en una zona de llarga tradició minera en la producció, sobretot, de plom. Precisament, l’explotació de la galena i el plom s’estenia i havia estat important des d’antic al territori que abraça l’àrea del Molar–Bellmunt–Falset. El responsable que es focalitzessin els esforços en l’explotació de l’argent en aquesta zona a mitjan segle XIV va ser, sens dubte, el segon comte de Prades: l’infant Pere d’Aragó, fill del monarca Jaume II d’Aragó i Blanca d’Anjou. El qual, de fet, va ser comte de les Muntanyes de Prades des del 1342 fins al 1358. Així doncs, en la present tesi doctoral, es treballen diversos aspectes relacionats amb l’activitat minera i metal·lúrgica de l’argent que es va desenvolupar a Falset mentre va ser comte de Prades l’infant Pere. De fet, el tema s’aborda de forma exhaustiva i des d’una perspectiva àmplia. Ara bé, per centrar el treball, s’analitzen tres àmbits temàtics bàsics: la regulació normativa de l’explotació de l’argent, la gestió i organització estructural de l’activitat i, finalment, la producció de les mines. Així, essencialment a partir de la transcripció i l’anàlisi acurat de documentació conservada a l’Arxiu Ducal de Medinaceli a Catalunya, s’articulen els diferents apartats.

Por lo tanto, en la presente tesis doctoral, se trabajan diversos aspectos relacionados con la actividad minera y metalúrgica de la plata que se desarrolló en Falset mientras fue conde de Prades el infante Pedro. De hecho, el tema se aborda de forma exhaustiva y desde una perspectiva amplia.

In the mid 14th century, silver mining exploitation was boosted and strengthened in the County of Prades Mountains and Barony of Entença. This dominion, which was created in 1324, was a territorially and lordly indivisible ensemble under the rule of only one lord. In this broad frame, the noble metal exploitation was specially developed in the zone of influence of Falset (Priorat, Catalonia). This city was the administrative capital of the wide dominion. In fact, there was a boom in silver exploitation in an area where lead production, above all, had been developed for a long time. Precisely, galena and lead exploitation had been important in the area made up of Molar–Bellmunt–Falset territory, where this activity had been present since Prehistory. Without a doubt, the second count of Prades was the main responsible for focusing all the efforts in silver exploitation in this area in the mid 14th century. He is usually called Infante Peter of Aragon, because he was King James II of Aragon and Blanca of Anjou’s son. In fact, this infante was count of Prades Mountains from 1342 to 1358. Therefore, the present doctoral thesis deals with several aspects related to silver mining and metallurgy which were developed in Falset while Infante Peter was count of Prades. Actually, this subject is covered in a thorough way and from a broad perspective. Nevertheless, three main issues are analysed in order to focus attention on this subject: silver exploitation ordinances, administration and structural organization of the activity and, finally, mines production. In this way, the different book sections are primarily organised using the information obtained by transcribing and studying documents from Medinaceli’s Ducal Archive in Catalonia.

Full textAbstract:
This chapter explains how Marxist scholars assert that mining was pre-capitalist before the sixteenth century. They write liberally about what they call the feudal utility of silver mining. The essence of this idea is that mines were fiefs, exploited by independent miners and serfs who paid rent in money, ores, or kind. This circumstance, the argument goes, was possible because feudal lords held legal claims over the mines and thus had the capacity to coercively extract surplus. The chapter also demonstrates that the Marxists' interpretation of mining implies that it was ahead of its feudal times. Feudal lords painfully learned the most enduring lesson of the moment, that a legal title to ore-yielding land made no mine. The industry organized productive capital in a dynamic, hierarchical structure rooted in private entrepreneurs' investments in mining claims. It was no peaceful development; after all, European mining regions were not immune to their times.

Full textAbstract:
Copper objects first circulated on the Greek mainland during the fifth millennium BC and shortly after in the islands of the southern Aegean (Zachos 2007). The earliest metalwork of Late Neolithic date comprised small objects such as awls, beads, and bracelets. Metal use gradually expanded during the Chalcolithic stage that followed, with production of larger items such as axeheads. There are parallels with the development of early metallurgy in the Balkans, however there was much less copper in circulation. This may be explained by the absence of early copper mines comparable to Rudna Glava or Ai Bunar in either Greece or the Aegean islands. The use of metal in the Aegean expanded significantly during the third millennium BC, with the emergence of a flourishing culture that had extensive seafaring contacts (Renfrew 1972). The importance of maritime trade in this region dates from the Neolithic when the island of Melos was a major source of obsidian across the east Mediterranean. Lead isotope analysis confirms that the copper, lead, and silver used by the Cycladic culture of the Early Bronze Age came from ore sources on many of those islands (Stos-Gale 1989). These metals were traded widely across the Aegean, with supply also into mainland Greece. While no copper mines have been identified, lead/silver workings of this period are recorded at Lavrion and at Ayios Sostis on Siphnos (Wagner et al. 1980). There are numerous deposits of copper ore and other metals in mainland Greece. No prehistoric copper mines have been identified; however, the potential has been examined by lead isotope analysis. An examination of various ore deposits in northern Greece, including examples in Thrace and eastern Macedonia, Thasos, the Pangeon Mountains, and Chalkidki did not reveal any likely sources of copper in prehistory. Samples were also taken in east-central Greece, from mineralization in the Othrys Mountains where there are several indications of ancient mining. Radiocarbon dates indicate copper mining at various locations there during the first millennium BC (Gale and Stos-Gale 2002: table 3).

This chapter discusses the place of mining in the history and theory of capitalism. It talks about Adam Smith who explained that of all the expensive and uncertain projects which bring bankruptcy upon the greater part of the people who engage in them, there is none perhaps more perfectly ruinous than the search for new silver and gold mines. However, Adam Smith could not anticipate the innovative industrial force that mining would have in nineteenth-century Britain. Nor did Smith see the force of mining in the movement toward land improvements in northern Europe. Other than reflecting negatively upon the coal mines of England, Smith said very little about the relationship between mining and wealth.

This chapter provides the mining history of the mountains of the rest of the world. It begins with England in which major silver discoveries took place in Bere Ferrers or Bere Ferris, a valley of the Tamar River in North Devon, southwest of Dartmoor, and at Combe Martin in the north after the mid-thirteenth century. However, English mines were challenging as they were physically distant from the central arteries of international trade of continental Europe and the commercial cities with continental catchment areas. This chapter also talks about silver mining that flourished in the Persian Province of Khorasan, the Samanid region of Transoxiana, and the Hindu Kush. These are the lands of the most spectacular mountain heights, where mountains piled up one behind another and mountain development assumes its grandest forms. It ends with mining history in India in which its mining exploits did not compete with the achievements of European mining regions. Mining in Zawar endured technical difficulties. Geologist Bagghi states that miners worked on hard siliceous quarzitic ore bodies, where drilling today calls for the use of tungsten carbide bits.
