Conflicting Interests of Trading Companies and Causes of the South African War, 1899-1902

The author examines the economic aspects of the South African colonial exploration by the Europeans in the representation of accumulated contradictions between business organizations, which ultimately became a cause of the 1899-1902 conflict. Based on the study of Dutch East India Company’s activities in this region, as well as the specifics of the settlement establishment by the British and Boers, attention is paid to the root causes of the disharmonious economic situation of the rivalling parties, taking place before the discovery of gold deposits in the Witwatersrand (1886). The changing regional supremacy of the Cape colony and the other British possessions, as well as Boer States (the Republic of South Africa – Transvaal and the Orange Free State) has been periodized. The factors of the 1899 armed conflict have been structured to reveal the conflicting interests of trading companies which had sought to monopolize the business for extraction of valuable mineral raw materials. The author concludes that the main reason for the South African War was the desire of British trading companies to gain access to rich gold deposits in the Boer-populated Transvaal and form a single English-based state in South Africa. In order to achieve such goal, the British tried their best at delaying peace initiatives of the Boers, putting forward various contradictory demands to them, using the armies of private companies to conduct raids and sabotaging the formation of a federal state in the region. We have discovered the preposterous look of the British pretext for the outbreak of war, based on the protection of the Boer states English-speaking population interests, which had been supposed to initiate an uprising. The South African War became not only a place, where new methods of warfare were applied, and a “black hole” for the UK budgetary expenditures, but also a profitable market for new types of weapons and military equipment, which allowed their manufacturers to make considerable profits.

Eksplorasi dan Eksploitasi Penambangan Emas Lebong Donok (Bengkulu) Tahun 1897-1942

This study describe the Exploration and Exploitation gold mining in Lebong Donok, (Bengkulu) in 1897-1942. This research uses the historical method of the process: Heuristics, or data collection, then continued the procces of source criticism and interpretation of data, the final stage is the writing of history so that this research can be completed. The results showed that the first person to explore the Lebong Donok gold tambourine was Eugene Kassel. Eugene Kassel conducted a study in Lebong. The results of his research caught the attention of the owner of a mining company in Batavia so the company decided to explore the mine through Lebong Goud Syndicaat. The Dutch East Indies government granted management concessions to a Dutch private company named Mijnbouw Maatschappij Redjang Lebong in 1899 under the mining administrator H.J.A. Sanders, after the discovery of gold deposits at Lebong Donok in 1896 and the estabilishment of the company on 10 February 1897. The results of exploitation carried out by the Dutch East Indies government through private company Mijnbouw Maatschappij Redjang Lebong in Lebong Donok is very profitable and adds to the Dutch East Indies government.

Geological and geochemical characteristics and prospecting potential of the Daqiao hot spring‐type gold deposit in the west Qinling Orogen

Great breakthroughs have recently been made in discovery of gold deposits in the west Qinling Orogen, which is an important component of the Central China Orogen, the most important gold metallogenic region in China, with numerous developed gold deposits. The Daqiao gold deposit is located in the west Qinling region of the Central China Orogen at the convergence of the Minxian–Dangchang–Liangdang and Zhouqu–Chengxian thrust and nappe tectonic belts. The gold orebodies exist in the silicolites occurring in a funnel shape at the lithologic unconformity between the Triassic lower limestone and argillaceous slate; ore types are dominated by siliceous breccia type, and ores are dominated by brecciated, filmy, crusty, veinlet–mesh vein, and porous structures, with silicification and kaolinization developed widely. The silicolites have δ30Si = −0.7–0.4‰ and δ18O = 12.8–17.9‰; their formation temperature calculated with an oxygen isotope thermometer is 108–182 °C. These features indicate characteristics of hot spring‐type gold deposits. The δ34S values of the pyrite (from 1.6‰ to 9.41‰ in the early period and −11.6‰ to 9.82‰ in the late period) and the lead isotope results show that the metallogenic materials were from a mixture of magmas and strata in the early period and from strata in the late period. The zircon SHRIMP U–Pb age of the granodiorite related to mineralization is 230.9 ± 1.9 Ma. A comprehensive study of the Daqiao gold deposit indicates that it is a hot spring‐type gold deposit, formed in an intracontinental orogenic environment.
