Abstract The gold and silver endowment of Korea has historically been well known, with records alluding to production as far back as 1122 BC. The main gold production period was from 1925 to 1943 during the Japanese occupation of Korea, with more than 1 Moz recorded in 1939. Muguk was the most productive gold mining operation, located within the central region of South Korea, with a recorded 590 koz of gold produced from 1934 to 1998 (first mined in AD 912). The majority of the historical mining operations were closed by government order in 1943 during the Second World War and never reopened. A number of small mines operated between 1971 and 1998, with limited production during a period of gold prices generally lower than at present (~25–50% of current inflation adjusted prices, apart from a four-year period 1979–83). It is likely that significant resources remain within these historical mining areas. Gold-silver deposit types historically recognized and exploited in Korea include placers and orogenic and intrusion-related vein systems. Only more recently have epithermal vein and breccia systems been recognized. This is not surprising, given that the geologic and tectonic setting of the Southern Korean peninsula is prospective for epithermal precious metal deposits, spatially associated with basin-scale brittle fault systems in Cretaceous volcanic terranes. South Korea is an underexplored jurisdiction, with limited modern exploration and drilling until the mid-1990s, when Ivanhoe Mines Ltd. discovered the Gasado, Eunsan, and Moisan epithermal gold-silver deposits, all of which became mines. Exploration was limited for another 20 years until Southern Gold Ltd., an Australian Securities Exchange (ASX)-listed company, commenced regional-scale exploration for epithermal deposits, using a strategy similar to that successfully employed by Ivanhoe.

The discovery of gold in Australia forced many changes to theory on the occurrence and origin of gold deposits. Initial discoveries appeared to confirm existing ideas on the global distribution of gold-bearing terrains. Later discoveries and research would show that this confirmation was largely coincidental, but nevertheless helpful in early prospecting. Prior to the first Australian gold rush, theoretical predictions of payable gold were made by Sir Roderick Murchison and Rev. W. B. Clarke based on knowledge of accidental gold finds and geological analogy with known areas of significant gold occurrence, particularly the Ural region in Russia. These predictions were overwhelmed when Edward Hargraves, realised he might be able to spark a gold rush that would prove the existence of payable gold. Hargraves travelled to the Bathurst region of New South Wales where numerous gold finds had already been made and with local guides, prospected Lewis Ponds Creek and the Macquarie River. He demonstrated the methods of alluvial mining, to John Lister and William and James Tom enabling them to find sufficient alluvial gold to initiate a gold rush. The crowd of attracted diggers demonstrated the existence of a payable goldfield. The unstoppable first rush resulted in the pragmatic introduction of government regulation and administration to allow alluvial gold mining. Other discoveries of payable goldfields quickly followed. As the local scientific expert on gold, W. B. Clarke was commissioned to conduct two extensive surveys of the goldfields between 1851 and 1853. Clarke also drew on his geological knowledge to provide practical advice to the thousands of prospecting gold diggers. Gold-bearing quartz reefs and lodes were discovered, but it was predicted that these could not be mined economically. Theory also predicted that the reef gold would not continue to depth. Practical observations and mining experience from the numerous discoveries led to revision of the widely held dicta on gold occurrence. Alluvial gold was found in a range of settings, including the recent drainage and ancient and buried leads. A wider variety of rock types was recognised as favourable for gold. Different styles of reef gold were identified and found to be economically mineable to great depth. Evolving ideas on the origin of gold deposits were widely discussed, tested, and refined. Of the many players involved in the early discovery of gold in Australia, Clarke, Hargraves and Murchison probably had the greatest overall influence in terms of theoretical predication and practical outcomes that initiated the Australian gold-mining industry.

Colonial Australian science grew by a process of transplantation, adaptation, and innovation in response to local conditions. The discovery of gold in 1851, and the location of vast resources of other minerals, transformed the colonies, as it did the imperial economy. In this process, the role of mining engineering and mining education played a significant part. Its history, long neglected by historians, illuminates the ways in which the colonial universities sought to guide and direct this engine of change, conscious both of overseas precedent and local necessity. This paper considers the particular circumstances of New South Wales, and the role of the University of Sydney, in seizing the day—and producing a degree—that lasted nearly a century.

<div><p><em>This research sets out to unravel the history of Lennox Mine from its inception in 1970 tracing the contribution of the mine to the economic development of Zimbabwe from its colonial beginnings up to the current period when the new visionary owner, Honourable Gandiwa Moyo, Deputy Minister of Mines who inherited a dysfunctional mining enterprise set it on course again as a pillar for economic production, under the erstwhile management of the Lennox General Mine Manager, Edgar Mashindi. The research seeks to explore how the mine management, operating under harsh economic conditions prevailing in Zimbabwe has empowered African entrepreneurs and employees and resuscitated life to the dying town of Mashava. Mashava is back on its former footing as a lively booming bedroom town of Masvingo City, forty kilometres away: supermarkets, bars, salons, housing projects, new shops are sprouting up once again as Mashava claims its proud place as a gold producing enclave of the Zimbabwean economy. Hundreds of unemployed youths from all over Zimbabwe have descended on Mashava, seeking employment and investment opportunities resulting in an unprecedented economic boom which is being felt country wide. Only recently hordes of flea female market traders opened shop at Mashava to sell clothes, shoes, household furniture and related paraphernalia to local residents and they reported that business was excellent and confirmed business plans to return every month end to sell their wares. A few years back Mashava was an abandoned mining town with all services shut down after the Capitalist oligarchic organization which owned Mashava ceased all operations and expropriated capital to Australia and Europe and started out new commercial ventures in those respective European countries. The Zimbabwean Electricity Supply Association [ZESA] shut down electricity supplies to Lennox Mine after the mine incurred a debt of close to a quarter of a million. Today, Lennox has agreed on a payment plan and electricity has been reopened triggering high gold productivity as the mine returns to its normal production levels.</em></p></div>

The ArgumentThe thesis of this paper is that there are three basic processes by which a technological innovation is fitted into an existing culture: (1) Rejection, in situations where all interested groups are satisfied with a traditional technology and reject apparently superior innovations because they would force unwanted changes in technology and ideology; (2) Acceptance, in situations where a new technology is embraced by all because it appears to serve the same social and ideological functions as an inferior, or inoperative, traditional technology; and (3) — most commonly in complex societies — conflict over acceptance or rejection, in situations where a new technology introduced or proposed by one group, who perceive it as advancing their interests, is resisted by another group, who perceive it as threatening their welfare. A traditional tripartite concept of culture is employed, distinguishing technology, social organization, and ideology. Four case studies are introduced to illuminate the issue: the Thonga tribesmen of Mozambique, whose occupation as gold and diamond miners at first suited perfectly the requirements of the Thonga lineage and marriage system; the Yir Yoront of Australia, an aboriginal group who found that the steel axe introduced by whites disrupted the patriarchal status system and confounded their mythology; the Senecas, an American Indian tribe that for generations rejected male plow agriculture because their way of life was organized around female horticulture, but who took up male agriculture at the urging of a prophet when traditional male roles disintegrated on the reservation; and the anthracite miners and mine operators of nineteenth-century Pennsylvania, who discovered that fundamental changes in both social organization and ideology were needed in order to cope with catastrophically high rates of industrial accidents attendant on the new system of deep-shaft mining.

Full textAbstract:
The history of mining and exploration in Panama is a case study of the evolution of mining in a tropical, island arc environment in the New World from prehistoric to modern times over a period of ~1900 years. Panama has a strong mineral endowment of gold (~984 t), and copper (~32 Mt) resulting in a rich mining heritage. The mining history can be divided into five periods. The first was the pre-Columbian period of gold mining from near the start of the Current Era at ~100 CE to 1501, following the introduced of gold metalwork fully fledged from Colombia. Mining of gold took place from placer and vein deposits in the Veraguas, Coclé, Northern Darien and Darien goldfields, together with copper for alloying. Panama was the first country on the mainland of the Americas to be mined by Europeans during the Spanish colonial period from 1501-1821. The pattern of gold rushes, conquest and settlement can be mapped from Spanish records, starting in Northern Darien then moving west to Panama in 1519 and Nata in 1522. From here, expeditions set out throughout Veraguas over the next century to the Veraguas (Concepción), Southern Veraguas, Coclé and Central Veraguas goldfields. Attention returned to Darien in ~1665 and led to the discovery of the Espíritu Santo de Cana gold mine, the most important gold mine to that date in the Americas. The third period was the Republican period following independence from Spain in 1821 to become part of the Gran Colombia alliance, and the formation of the Republic of Panama in 1903. This period up to ~1942 was characterized by mining of gold veins and placers, and manganese mining from 1871. Gold mining ceased during World War Two. The fourth period was the era of porphyry copper discoveries and systematic, regional geochemical exploration programs from 1956 to 1982, carried out mainly by the United Nations and the Panamanian government, as well as private enterprise. This resulted in the discovery of the giant porphyry copper deposits at Cerro Colorado (1957) and Petaquilla (Cobre Panama, 1968), as well as several other porphyry deposits, epithermal gold deposits and bauxite deposits. The exploration techniques for the discovery of copper were stream sediment and soil sampling, followed rapidly by drilling. The only mine developed in this period was marine black sands for iron ore (1971-1972). The fifth and current period is the exploration and development of modern gold and copper mines since 1985 by national and foreign companies, which started in response to the gold price rise. The main discovery methods for gold, which was not analyzed in the stream sediment surveys, were lithogeochemistry of alteration zones and reexamination of old mines. Gold mines were developed at Remance (1990-1998), Santa Rosa (1995-1999 with restart planned in 2020) and Molejon (2009-2014), and the Cobre Panama copper deposit started production in 2019. The level of exploration in the country is still immature and there is high potential for the discovery of new deposits.

Full textAbstract:
With successful exploration of deposits often lagging behind mineral extraction, and the international price of gold showing no signs of recovery, mining companies are under pressure to reassess their strategies. The decision whether or not to close a mining activity is the outcome of a process of adapting expectations to a changing economic and geological environment. Part of the literature emphasizes the role of the mineral price and operating costs. However, the extent, pace and intertemporal allocation of metal recovery is in practice determined by a complex interaction of both these with other factors. Following a review of theoretical interpretations, and a reformulation of associated hypotheses, binary-response models are applied to a sample of gold mines in mainly three major southern hemisphere producers (Australia, South Africa and Chile).

Full textAbstract:
ABSTRACTThe ‘Lobi’ region in what is today southern Burkina Faso is frequently mentioned in historical accounts of gold mining in West Africa. However, little is known about the actual location of the gold mines or about the way gold mining and trade were organized in precolonial times. This article points out that some previous hypotheses about precolonial gold mining, trade and the sociopolitical organization of this region are flawed, partly because ‘Lobi’, as the name for both the region and its inhabitants, is misleading. In fact, the references to ‘Lobi’ merge two distinct gold-producing zones along the Mouhoun river, about 200 km from each other. The present-day populations of southern Burkina who have settled there since the eighteenth century do not know who was mining gold prior to their arrival, and many of them have not been involved in gold mining at all due to conceptions of gold as a dangerous substance.

Full textAbstract:
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:
The pervasive importance of gold mining in modern South Africa has become embedded in South African historiography. Despite this, little research has been done to ascertain its impact on the other major sector of the economy, agriculture.The gold mines had a profound effect upon one particular branch of agriculture – beef farming. The mines purchased large amounts of beef and were able to use their buying power to confront beef farmers in the marketplace. In the recession following the First World War, the mines were caught in a profitability crisis that was to lead to the Rand Revolt in 1922. One of the ways in which mining attempted to ease its position was by cutting back on the cost of the meat it supplied to its African labour force. This initially involved co-operation with a powerful cold-storage company, big ranchers and a number of smaller farmers to form a Meat Producers Exchange. This fragile alliance fell apart when farmers, themselves on the verge of bankruptcy, attempted to take control of the Exchange and raise beef prices. The farmers failed and in 1923 the exchange collapsed.The victory of the mining and cold-storage companies rested on a number of factors. Farmers were unable to organize effectively because of the defection of ranchers to the mines. Changing economic conditions in 1922 and 1923 permitted the mines to terminate their co-operation with beef farmers. Finally the mines were able to call upon the state for support. The state ensured the demise of the Exchange and the defeat of the beef farmers. In the process it showed itself capable of intervening decisively to protect the interests of certain sections of capital.

The gold metallogeny of Australia is predominantly confined to the Archaean and Palaeozoic Provinces. The Archaean gold occurrences are predominantly hosted in ultramafic-mafic dominated greenstone belts, with less associated tofelsic-volcanic and sedimentary sequences. Most gold occurrences are confined to shear zones or faults, and adjacent discoveries of economic laterite-hosted deposits, host rocks. Recent are presently under investigation and will supply a significant proportion of production in the future. The Proterozoic gold deposits of Australia , are confined to geosyncinal sequences, commonly turbidites (eg: Telfer), with other hydrothermal deposits associated directly to granites. An important feature of the North Australian Craton deposits, is the spatial association of most deposits to granite bodies, although a genetic link has not been established conclusively. The Roxby Downs deposit in South Australia is a unique occurrence of gold in association to copper, uranium and R.E.E. This deposit is tentatively related to intraplate alkaline-magmatism, with further work necessary. The most significant recent discovery of gold mineralization in Australia is in the Drummond Basin in Queensland. This epithermal is tentatively related to mineralization within the Georgetown Inlier. The latter mineralization is Permo-Carboniferous, in a Proterozoic (and possibly Archaean) sequence of schists. It is tentatively suggested that all the gold mineralization in northern Queensland may be related to single tectonic event, a feature which requires further study . Other mineralization in the Phanerozoic includes the turbidite-hosted metamorphogenic deposits of Victoria, the rift related deposits in New South Wales and magmatic related deposits in Queensland. The gold deposits in Australia may in the future be classified in a tectonogeological framework, similiar to the layout of this dissertation, particularly once further data becomes available on recent discoveries.

Full textAbstract:
Gold-bearing volcanic breccia complexes are the major sources of gold in the Tasman Fold Belt System in north Queensland. The Tasman Fold Belt System represents the site of continental accretion as a series of island-arcs and intra-arc basins with accompanying thick sedimentation, volcanism, plutonism, tectonism and mineralisation. In north Queensland, the fold belt system comprises the Hodgkinson-Broken River Fold Belt, Thomson Fold Belt, New England Fold Belt and the Georgetown Inlier. The most numerous ore deposits are associated with calc-alkaline volcanics and granitoid intrusivesof the transitional tectonic stage of the fold belt system. The formation and subsequent gold mineralisation of volcanic breccia complexes are related to Permo-Carboniferous magmatism within the Thomson Fold Belt and Georgetown Inlier. The two most important producing areas are at Mount Leyshon and Kidston mines, which are high tonnage, low-grade gold deposits. The Mount Leyshon breccia complex was emplaced along the contact between CambroOrdovician metasedimentary and metavolcanic rocks, and Ordovician-Devonian I-type granitoids of the Lolworth-Ravenswood Block. The Kidston breccia complex is located on a major lithological contact between the Early to Middle Proterozoic . Einasleigh Metamorphics and the Silurian-Devonian Oak River Granodiorite. The principal hosts to the gold mineralisation at the Mount Leyshon and Kidston deposits, are breccia pipes associated with several episodes of porphyry intrusives. The goldbearing magmatic-hydrothermal and phreatomagmatic breccias post-date the development of a porphyry-type protore. The magmatic-hydrothermal breccias were initially emplaced without the involvement of meteoric-hydrothermal fluids, within a closed system. Later magma impulses reached higher levels in the cooled upper magma chamber, where meteoric water invaded the fracture system. This produced an explosive emplacement of phreatomagmatic breccias, as seen at Mount Leyshon. Widespread sericitisation and pyrite mineralisation are common, with cavity fill, disseminated and fracturelveincontrolled gold and base metal sulphides. The Kidston and Mount Leyshon breccia complexes have hydrothermal alteration and mineralisation characteristics of the 'Lowell-Guilbert Model'. However, the argillic zone is generally not well defined. The gold travelled as chloride complexes with the hydrothermal fluids before being deposited into cavities and fractures of the breccias. Later stage epithermal deposits formed at the top of the breccia complexes that were dominantly quartz-adularia-sericite-type. The erosion, collapse and further intrusion of later porphyry phases allowed the upper parts of the breccia complexes to mix with the lower hydrothermal systems. Exploration for gold-related volcanic breccia complexes is directed at identifying hydrothermal alteration. This is followed by detailed ground studies including geological, mineralogical, petrological and geochemical work, with the idea of constructing a 'model' that can be tested with subsequent subsurface work (e.g. drilling). Geomorphology, remote sensing, geochemistry, geophysics, petrology, isotopes and fluid inclusions are recommended exploration techniques for the search of gold-bearing volcanic breccia complexes. Spectral remote sensing has especially become an important tool for the detection of hydrothermal alteration. Clay and iron minerals of the altered rock, within the breccia complexes, have distinctive spectral characteristics that can be recognisable in multispectral images from the Landsat thematic mapper. The best combination of bands, when using TM remote sensing for hydrothermally altered rock, are 3/5/7 or 4/5/7. The breccia complexes have exploration signatures represented as topographic highs, emplaced within major structural weaknesses, associated I-type granitic batholiths, early potassic alteration with overprint of sericitic alteration, and an associated radiometric high and magnetic low. The exploration for gold-bearing volcanic breccia complex deposits cannot be disregarded, because of the numerous occurrences that are now the major gold producers in north Queensland.

Full textAbstract:
Stochastic simulation of rocktypes, or the geometry of the geology, is a major area of continuing research as earth scientists seek a better understanding of an orebody as a precursor to the assignment of continuous rock properties, allowing more economically appropriate decisions regarding mine planning. This thesis analyses the suitability of particular geostatistical rock type modelling algorithms when applied to the five rocktypes evident in drill hole data from the Big Bell gold mine near Cue, Western Australia. The background of the geostatistical theory is considered, in particular the concept of the random function model and the link between the categorical statistics determined from the drill hole data and the three models used for estimation and simulation. The commonly applied indicator kriging (IK) and sequential indicator simulation (SIS) algorithms are compared in a non-sedimentary gold deposit environment to the more computationally demanding and more complex plurigaussian simulation (PGS). Comparisons between the three models are made by examining global and regional rocktype (lithotype) proportions of the outputs of the models, both visually and empirically. The models are validated by considering the contacts which occur in reality between different lithotypes and the proportion of contacts which do not conform to this reality in each of the models. This „inadmissible contact‟ ratio measures the short range validity of the estimation and simulation techniques. Finally, cores taken from the output of the models are compared to the drill hole data in terms of transition proportions between the twenty five possible transitions for the five lithotypes. Inadmissible contacts were at a minimum with PGS, and the visual and empirical natures of the PGS output were closely linked to the reality of the drill hole data. Whilst each model produced similar 3D images, PGS was a realistic balance between the clustering effect produced by IK and the fine mosaic effect from SIS. The PGS output numerically outperformed the other two models in terms of admissible contacts and connectivity, most closely matching the drill hole data. All results indicate that, whilst demanding to implement, PGS produces the most adequate model of the study region.

Full textAbstract:
Mining induced seismic activity and rockbursting are critical concerns for many underground operations. Seismic activity may arise from the crushing of highly stressed volumes of rock around mine openings or from shear motion on planes of weakness. Shear-slip on major planes of weakness such as faults, shear zones and weak contacts has long been recognized as a dominant mode of failure in underground mines. In certain circumstances, it can generate large seismic events and induce substantial damage to mine openings. The Big Bell Gold mine began experiencing major seismic activity and resultant damage in 1999. Several seismic events were recorded around the second graphitic shear between April 2000 and February 2002. It is likely that the seismic activity occurred as a result of the low strength of the shear structure combined with the high level of mining induced stresses. The stability of the second graphitic shear was examined in order to gain a better understanding of the causes and mechanisms of the seismic activity recorded in the vicinity of the shear structure as mining advanced. The data were derived from the observation of the structure exposures, numerical modelling and seismic monitoring. The numerical modelling predictions and the interpreted seismic monitoring data were subsequently compared in order to identify potential relationships between the two. This thesis proposes the Incremental Work Density (IWD) as a measure to evaluate the relative likelihood of shear-slip induced seismic activity upon major planes of weakness. IWD is readily evaluated using numerical modelling and is calculated as the product of the average driving shear stress and change in inelastic shear deformation during a given mining increment or step. IWD is expected to correlate with shear-slip induced seismic activity in both space and time. In this thesis, IWD was applied to the case study of the second graphitic shear at the Big Bell mine. Exposures of the second graphitic shear yielded information about the physical characteristics of the structure and location within the mine. Numerical modelling was used to examine the influence of mining induced stresses on the overall behaviour of the shear structure. A multi-step model of the mine was created using the three- dimensional boundary element code of Map3D. The shear structure was physically incorporated into the model in order to simulate inelastic shear deformation. An elasto-plastic Mohr-Coulomb material model was used to describe the structure behaviour. The structure plane was divided into several elements in order to allow for the comparison of the numerical modelling predictions and the interpreted seismic data. Stress components, deformation components and IWD values were calculated for each element of the shear structure and each mining step. The seismic activity recorded in the vicinity of the second graphitic shear was back analysed. The seismic data were also gridded and smoothed. Gridding and smoothing of individual seismic moment and seismic energy values resulted in the definition of indicators of seismic activity for each element and mining step. The numerical model predicted inelastic shear deformation upon the second graphitic shear as mining advanced. The distribution of modelled IWD suggested that shear deformation was most likely seismic upon a zone below the stopes and most likely aseismic upon the upper zone of the shear structure. The distribution of seismic activity recorded in the vicinity of the shear structure verified the above predictions. The seismic events predominantly clustered upon the zone below the stopes. The results indicated that the seismic activity recorded in the vicinity of the second graphitic shear was most likely related to both the change in inelastic shear deformation and the level of driving shear stress during mechanical shearing. Time distribution of the seismic events also indicated that shear deformation and accompanying seismic activity were strongly influenced by mining and were time-dependant. Seismic activity in the vicinity of the second graphitic shear occurred as a result of the overall inelastic shear deformation of the shear structure under mining induced stresses. A satisfactory relationship was found between the spatial distribution of modelled IWD upon the shear structure and the spatial distribution of interpreted seismic activity (measured as either smoothed seismic moment or smoothed seismic energy). Seismic activity predominantly clustered around a zone of higher IWD upon the second graphitic shear as mining advanced. However, no significant statistical relationship was found between the modelled IWD and the interpreted seismic activity. The lack of statistical relationship between the modelled and seismic data may be attributed to several factors including the limitations of the techniques employed (e.g. Map3D modelling, seismic monitoring) and the complexity of the process involved.

Full textAbstract:
This thesis analyses the establishment of a health and safety system on the Witwatersrand gold mines in the period between the end of the South African War and the eve of World War Two. The period has been chosen, firstly, because the South African War had seriously disrupted production and the industry virtually had to start up again from scratch; secondly, because it was during this period that mine and state officials began to seriously investigate the reasons for the appalling mortality and morbidity rates on these mines; and, thirdly, because during this period some improvements did occur which were significant enough to enable the industry to warrant the lifting, in the latter part of the 1930s, of the ban on tropicals, enforced since 1913 as a result of their extremely high mortality rate. In the first thirty years of the twentieth century about 93 000 African miners died disease-related deaths and in the same period some 15000 African miners were killed in work-related deaths. In attempting to establish why so many African miners died, the thesis attempts to identify the diseases and accidents that caused these deaths and considers what attempts were made to bring mortality and morbidity rates down. Whilst the thesis is neither a history of gold mining in South Africa nor an economic history of South Africa in the period 1901 to 1939, it nevertheless, as detailed in the first chapter, places the health and safety system within the context of the wider political and economic forces that shaped the mining industry in this period. The need for a productive and efficient labour force, vital for the industry'S survival during a number of profitability crises in this period, forced the industry to reassess compound structures, nutrition and eventually the health of its work force. These issues of compounds, work and diet are discussed in chapters two, three and four. Appalling living and working conditions led to a high incidence of pulmonary diseases - TB, silicosis and pneumonia - which were the principal killers on the mines. Attempts to cure or prevent their occurrence are discussed in chapter five. Fear of disruptions to production ensured that the mining industry eventually also devoted considerable resources to accident prevention, a theme which is discussed in chapter six. The thesis concludes that the mining industry for much of this period was able to determine the pace of change; neither state officials nor African miners were able to significantly alter the tempo. In fact the industry was so successful that it was able to convince a number of government commissions in the 1940s that the migrant system had to stay, to ensure the wellbeing of the miner. This meant that despite considerable time, money and effort being spent on establishing a health and safety system on the gold mines, the mining industry was still of the opinion that the health of their workers was best served if they were sent home.

Full textAbstract:
Elinor Ostrom (2005: 238) assumes that in understanding the make up and behaviour of institutional systems governing natural resources: “Resource users are explicitly thought of as rational egoists who plunder local resources so as to maximise their own short-term benefits. Government officials are implicitly depicted, on the other hand, as seeking, the more general public interest, having the relevant information at hand and the capability of designing optimal policies.” This thesis examines the validity of this assumption through an historical analysis of the deep-level gold mining industry of the Witwatersrand, South Africa. The main focus of the assessment is on the institutions of ownership – that is, the development of mining rights and title legislation between 1886 and 2008. The study looks at the legislations’ transformation and implementation from the perspective of the gold mining industry – made up of the mining finance houses and the Chamber of Mines of South Africa – and that of the state. The transformation of the mining industry’s institutional framework was both a choice by government as well as that of the firms in the mining industry. The theoretical framework is constructed from four areas of economic thought. These include: the neoclassical and Keynesian schools of macroeconomic thought; industrial organisation and its relevance to the relationship between firms and the market; institutional and new institutional economics; and finally property rights. The determinants of policy design and the impact of such design on firms and industry is examined. The development, implementation and use of the aforementioned legislation is examined from two perspectives, namely, that of preserver or exploiter. Throughout the history of this prominent South African industry, the motivation for action from the industry or government has oscillated between the two extremes of preserver or exploiter over the time period examined. The conclusion is drawn on an overall and broad focus of actions – with a strong focus on the most recent developments in mining legislation – post-1992.

Full textAbstract:
Beginning in 1848, the circum-Pacific world experienced dozens of gold rushes; they punctuated the histories of the United States, Canada, Australia, and New Zealand. Although individual prospectors dominate the national narratives of gold rushes, by the mid-1850s, industrial mining technologies had largely replaced individual miners with their pans and shovels. Notable among these industrial technologies was hydraulic mining, which used high-pressure water hoses to flush large amounts of gold-bearing gravel into sluice boxes saturated with mercury. Industrial mining technologies were portable—engineers who perfected hydraulic mining in California exported the practice to Australia, Canada, and New Zealand. Hydraulic mining exacted startling environmental costs: floods, deforestation, erosion, and toxic pollution. This chapter is by Andrew Isenberg.

Full textAbstract:
This chapter, by Ian Phimister, examines the global financial dynamics of the southern African and “Westralian” gold-mining share manias of the 1890s. Examination of both mining share markets suggests that, contrary to the conventional portrait painted of gold rushes, the defining picture is less one of prospectors rushing to pan for gold or peg claims than it is one of company promoters scurrying to fleece investors. The most frenzied activity was on the floor of the London Stock Exchange, not on the South African Highveld or the dry, dusty plains of Western Australia. More minted gold was found in London and the Home Counties than mined gold was located in Southern Africa or Western Australia. It is an exercise that once again questions the efficiency of late Victorian capital markets, even as it points to the consequences of the “portal of globalization” opened by finance.

Full textAbstract:
In the great nineteenth-century British world cycle of gold rushes, individualist wealth seeking became associated with democratic politics, and views about the public rather than private benefits of gold became increasingly the preserve of conservatives. In Georgia, governor George Gilmer declared in 1830 that the gold diggers were “appropriating riches to themselves, which of right equally belong to every other citizen of the state,” but he soon suffered electoral defeat. In 1850s California and Australia, individual miners were rapidly associated with a democratic and egalitarian future, even with the public good. This helps explain the oddly uncontested decisions to allow mining on public—and, in many places, private—land and use of public resources such as timber and water. This chapter is by David Goodman.

Full textAbstract:
This chapter, by Cassandra Mark-Thiesen, covers the Gold Coast’s moment in the imperial rush for gold. It highlights the frenzy surrounding the rush in British West Africa at the turn of the twentieth century, as witnessed in the ruthless promotion of local mining prospects in the foreign press. It also shows the circulations of capital, technology, labor, and ideologies inherent to such rushes, helping as they did to accelerate imperial expansion. At the same time, the chapter raises the topic of the limits of globalization. Connected to that point, and in examining changes at a regional level, it touches on the dynamic and changing nature of the indirect recruitment system that brought West African contract men to the mines.

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.

Full textAbstract:
This chapter, by Mae M. Ngai, locates the origins of the Chinese Question as a global racial discourse in the gold rushes of the nineteenth century and the broader context of the globalization of trade, credit, labor, and the rise of Anglo-American power. The gold rushes launched into motion hundreds of thousands of people from the British Isles, continental Europe, the Americas, Australasia, and China. Notably, they were the first occasions of large-scale contact between Westerners (Europeans and Americans) and Chinese. The chapter traces the development of anti-Chinese politics as it arose in the United States, Australia, and South Africa from conditions that were specific to gold rushes and gold mining in these regions, as well as how politics borrowed from each other and evolved into a global political discourse.

Full textAbstract:
One of the signature historical phenomena of the past 500 years has been the global expansion of European societies and their trans-Atlantic offshoots. The mercantile networks, commercial systems, and empires of conquest and colonization that formed the political and economic framework of that expansion involved the discovery and extraction of new mineral and agricultural resources, the establishment of new infrastructures of transport and communication, and the forcible relocation of millions of people. Another key component was the Columbian Exchange, the multiple transfers of people, animals, plants, and microbes that began even before Columbus, gathered pace after 1492, and were further fuelled as European settlement advanced into Africa, Australasia, and the Indian and Pacific Oceans. Donkeys evolved in the Old World and were confined there until the Columbian Exchange was underway. This chapter explores the introduction of the donkey and the mule to the Americas and, more briefly, to southern Africa and Australia. In keeping with my emphasis on seeking archaeological evidence with which to illuminate the donkey’s story, I omit other aspects of its expansion, such as the trade in animals to French plantations on the Indian Ocean islands of Réunion and Mauritius or, on a much greater scale, India to meet the demands of the British Raj. These examples nevertheless reinforce the argument that mules and donkeys were instrumental in creating and maintaining the structures of economic and political power that Europeans and Euro- Americans wielded in many parts of the globe. From Brazil to the United States, Mexico to Bolivia, Australia to South Africa, they helped directly in processing precious metals and were pivotal in moving gold and silver from mines to centres of consumption. At the same time, they aided the colonization of vast new interiors devoid of navigable rivers, maintained communications over terrain too rugged for wheeled vehicles to pose serious competition, and powered new forms of farming. Their contributions to agriculture and transport were well received by many of the societies that Europeans conquered and their mestizo descendants. However, they also provided opportunities for other Native communities to maintain a degree of independence and identity at and beyond the margins of the European-dominated world.

The Uranium Mine Remediation Exchange Group meetings of representatives from US, Canada, Australia and Germany have been going on since 1993. The novelty of UMREG 2002 was that the traditional group from was extended to representatives from CEEC, which have a history of uranium mining and milling and are presently involved or interested in environmental remediation (ER) of the legacy. The meeting was attended and/or presentations given by representatives from Czech Republic, Estonia, Hungary, Poland, Rumania, Russian Fed. and Slovenia. Furthermore, representatives from overseas countries, Brazil, Japan and Namibia having a present or historical uranium mining and the intent to remediate the consequences of the mining provided a contribution. The extended UMREG membership confirms the increasing interest in ER remediation and in following the “Good Environmental Remediation Practice” guidelines and provides a broader idea pool for the future UMREG meetings.

Full textAbstract:
Over the span of the 20th century, the global demand for metals and minerals has increased dramatically. This is associated with a general trend of declining ore grades from most commodities, meaning higher quantities of ore needed to be processed and thus more energy. Hence, quantifying the loss of mineral capital in terms of mass is not enough since it does not take into account the quality of the minerals in the mine. Exergy is a better indicator than mass because it measures at the same time the three features that describe any natural resource: quantity, composition and a particular concentration. For the sake of better understanding the exergy results, they are expressed in tons of Metal equivalent, tMe, which are analogously defined to tons of oil equivalent, toe. The aim of this paper is 1) to show the methodology for obtaining the exergy loss of mineral resources throughout a certain period of time and 2) to apply it to the Australian case. From the available data of production and ore grade trends of Australian mining history, the tons of Metal equivalent lost, the cumulative exergy consumption, the exergy decrease of the economic demonstrated reserves and the estimated years until depletion of the main base-precious metals are provided, namely: for gold, copper nickel, silver lead and zinc.

Full textAbstract:
13 uranium mines operated in the South Alligator Valley of Australia’s Northern Territory between 1953 and 1963. At the end of operations the mines, and associated infrastructure, were simply abandoned. As this activity preceded environmental legislation by about 15 years there was neither any obligation, nor attempt, at remediation. In the 1980s it was decided that the whole area should become an extension of the adjacent World Heritage, Kakadu National Park. As a result the Commonwealth Government made an inventory of the abandoned mines and associated facilities in 1986. This established the size and scope of the liability and formed the framework for a possible future remediation project. The initial program for the reduction of physical and radiological hazards at each of the identified sites was formulated in 1989 and the works took place from 1990 to 1992. But even at this time, as throughout much of the valley’s history, little attention was being paid to the long term aspirations of traditional land owners. The traditional Aboriginal owners, the Gunlom Land Trust, were granted freehold Native Title to the area in 1996. They immediately leased the land back to the Commonwealth Government so it would remain a part of Kakadu National Park, but under joint management. One condition of the lease required that all evidence of former mining activity be remediated by 2015. The consultation, and subsequent planning processes, for a final remediation program began in 1997. A plan was agreed in 2003 and, after funding was granted in 2005, works implementation commenced in 2007. An earlier paper described the planning and consultation stages, experience involving the cleaning up of remant uranium mill tailings and other mining residues; and the successful implementation of the initial remediation works. This paper deals with the final planning and design processes to complete the remediation programme, which is due to occur in 2009. The issues of final containment design and long term stewardship are addressed in the paper as well as some comments on lessons learned through the life of the project.

Alexander, Elinor. "Natural hydrogen exploration in South Australia." In PESA Symposium Qld 2022. PESA, 2022. http://dx.doi.org/10.36404/putz2691.
Full textAbstract:
South Australia has taken the lead nationally in enabling exploration licences for natural hydrogen. On 11 February 2021 the Petroleum and Geothermal Energy Regulations 2013 were amended to declare hydrogen, hydrogen compounds and by-products from hydrogen production regulated substances under the Petroleum and Geothermal Energy Act 2000 (PGE Act). Companies are now able to apply to explore for natural hydrogen via a Petroleum Exploration Licence (PEL) and the transmission of hydrogen or compounds of hydrogen are now permissible under the transmission pipeline licencing provisions of the PGE Act. The maximum area of a PEL is 10,000 square kilometres so they provide a large acreage position for explorers. PEL applicants need to provide evidence of their technical and financial capacity as well as a 5-year work program which could include field sampling, geophysical surveys (e.g., aeromagnetics, gravity, seismic and MT) and exploration drilling to evaluate the prospectivity of the licence for natural hydrogen. Since February 2021, seven companies have lodged 35 applications for petroleum exploration licences (PELs), targeting natural hydrogen. The first of these licences (PEL 687) over Kangaroo Island and southern Yorke Peninsula was granted to Gold Hydrogen Pty Ltd on 22 July 2021. As well as issuing exploration licences, a key role of the South Australian Department for Energy and Mining is to provide easy access to comprehensive geoscientific data submitted by mineral and petroleum explorers and departmental geoscientists since the State was founded in 1836. Access to old 1920s and 1930s reports, together with modern geophysical and well data has underpinned the current interest in hydrogen exploration. Why the interest? 50-80% hydrogen content was measured in 1931 by the Mines Department in gas samples from wells on Kangaroo Island, Yorke Peninsula and the Otway Basin, potential evidence that the natural formation of hydrogen has occurred. Iron-rich cratons and uranium-rich basement (also a target for geothermal energy explorers) occur in the Archaean-Mesoproterozoic Gawler Craton, Curnamona and Musgrave provinces which are in places fractured and seismically active with deep-seated faults. Sedimentary cover ranges from Neoproterozoic-Recent in age, with thick clastic, carbonate and coal measure successions in hydrocarbon prospective basins and, in places, occurrences of mafic intrusives and extrusives, iron stones, salt and anhydrite which could also be potential sources of natural hydrogen.

Full textAbstract:
Australia's and China's resources (e.g. Olympic Dam Cu-U-Au-Ag and Bayan Obo REE deposits) highlight how discovery and mining of iron oxide copper-gold (IOCG), iron oxide±apatite (IOA) and affiliated primary critical metal deposits in metasomatic iron and alkali-calcic (MIAC) mineral systems can secure a long-term supply of critical metals for Canada and its partners. In Canada, MIAC systems comprise a wide range of undeveloped primary critical metal deposits (e.g. NWT NICO Au-Co-Bi-Cu and Québec HREE-rich Josette deposits). Underexplored settings are parts of metallogenic belts that extend into Australia and the USA. Some settings, such as the Camsell River district explored by the Dene First Nations in the NWT, have infrastructures and 100s of km of historic drill cores. Yet vocabularies for mapping MIAC systems are scanty. Ability to identify metasomatic vectors to ore is fledging. Deposit models based on host rock types, structural controls or metal associations underpin the identification of MIAC-affinities, assessment of systems' full mineral potential and development of robust mineral exploration strategies. This workshop presentation reviews public geoscience research and tools developed by the Targeted Geoscience Initiative to establish the MIAC frameworks of prospective Canadian settings and global mining districts and help de-risk exploration for IOCG, IOA and affiliated primary critical metal deposits. The knowledge also supports fundamental research, environmental baseline assessment and societal decisions. It fulfills objectives of the Canadian Mineral and Metal Plan and the Critical Mineral Mapping Initiative among others. The GSC-led MIAC research team comprises members of the academic, private and public sectors from Canada, Australia, Europe, USA, China and Dene First Nations. The team's novel alteration mapping protocols, geological, mineralogical, geochemical and geophysical framework tools, and holistic mineral systems and petrophysics models mitigate and solve some of the exploration and geosciences challenges posed by the intricacies of MIAC systems. The group pioneers the use of discriminant alteration diagrams and barcodes, the assembly of a vocab for mapping and core logging, and the provision of field short courses, atlas, photo collections and system-scale field, geochemical, rock physical properties and geophysical datasets are in progress to synthesize shared signatures of Canadian settings and global MIAC mining districts. Research on a metamorphosed MIAC system and metamorphic phase equilibria modelling of alteration facies will provide a foundation for framework mapping and exploration of high-grade metamorphic terranes where surface and near surface resources are still to be discovered and mined as are those of non-metamorphosed MIAC systems.
