A stochastic model of the South African gold mines

Beelders, Owen 21 September 2023 (has links) (PDF)
A stochastic model of the South African Gold mines was constructed using Contingent Claims Analysis. This method allows the modelling of the major sources of uncertainty that the gold mines face, namely, uncertainty surrounding the future gold price, the exchange rate, the inflation rate, and the interest rate. The trajectories of these variables were modelled by stochastic differential equations. By applying the principles of contingent claims analysis, we could obtain a valuation partial differential equation that described the value of the mine contingent on the current values of the state variables mentioned above. This partial differential equation was solved by the Monte Carlo method and the solution was compared to current estimates of the mines' value.

Subcontracting in gold mining: Western Deep Level Mine, Carletonville

27 October 2008 (has links)
M.A. / This project examines the phenomenon of subcontracting as it occurs in the gold mining industry in South Africa. The point of departure for the researcher is that subcontracting is not something totally new in the gold mining industry. What seems to be new is the manner in which it is currently used and this could be attributed to variety of factors, which have made reliance on permanent workforce not viable for the employers. Downscaling and large-scale retrenchments have become the order of the day. This happens at a time when there is an unprecedented increase in the number of subcontract workers. This has raised concerns among organised labour who, feel that such form of atypical employment is meant to undermine the gains of the labour movement has gained over the years. Such perception is made even more real by the decline in labour standards. Contractors actively discourage their employees from joining trade unions. Subcontract workers are paid wages as low as R700 a month, while they are forced to work under dangerous conditions. Their terms of contracts are unilaterally changed without any consultation and they can be easily dismissed without any warning, in some cases dismissed for being injured at work. Tensions mount between subcontract and permanent workers as the latter view the former as a threat to their job security. All this makes subcontracting an interesting area of study and this is even made more so by the fact that little has been done to investigate subcontracting in South Africa's gold mines. / Prof. Peter.
