Subject area The case presents a responsible investment dilemma case. Swedish institutional responsible investors have to make a choice about their investment in Lonmin, a platinum mining company whose operation are located in South Africa and has been the theatre of workers’ killings. Study level/applicability The case targets MBA students and can be taught in a corporate finance course, a corporate governance course, a business ethics course or on sustainable and responsible investment. Case overview The teaching case follows the journey of Hilde Svensson, the head of equities for a Swedish responsible investor. She has been tasked to visit the site of Lonmin in South Africa which is the theatre of a tragic workers’ unrest that led to the killings of 44 workers in August 2012. She must decide what the best responsible investment strategy is to adopt with Lonmin for the future. Expected learning outcomes The students are expected to learn about what responsible investment entails and the dilemmas that can be faced by responsible investors. The case also gives insight to business students and the complexities of environment, social and governance (ESG) analysis and how to integrate financial and ESG analysis when you are a responsible investor.

The objective of the study was to illustrate the consequences of management oversight, as an element of poor corporate governance, of timeous stakeholder identification and engagement during a South African mining crisis. A secondary objective was to apply Quantitative Narrative Analysis (QNA), a methodology thus far mainly used in sociological research, to the understanding of this governance problem.An historical event in the South African platinum mining industry, the Marikana mining disaster, served as the unit of analysis for this case study. By utilising QNA, changes in stakeholder dynamics and salience were identified, based on available narrative from South African and UK newspaper articles spanning the period 1-24 August, 2012. The historical timeline of events and consequences were plotted, the main actors identified and the relationships between the actors and the events, mapped. A stakeholder analysis took the form of graphical stakeholder models, facilitating meaningful interpretation of the effects of the events that occurred. A typology of stakeholder categorisation was used to plot how the classification of stakeholders changed during the course of 24 days.The methodology used lays foundations for future methodological applications of QNA within stakeholder theory and presents opportunities for improved understanding of the impact of stakeholders on a company and on each other during a crisis event. The study contributes, practically, to an understanding of the importance of stakeholder identification and engagement during times of crises in order to assist leaders in engaging appropriately and timeously with different stakeholders groups, thereby promoting sound corporate governance.

The Norite Koppies Bushveld vegetation type boasts a distinctive and contrasting topography and species composition easily distinguished from that of surrounding areas. A phytosociological study was done on the leased mining area of the Impala Platinum Mining Company north of Rustenburg in the North-West Province. Similar norite koppies, situated west of the Norite Koppies Bushveld vegetation, and not yet mapped by Mucina Rutherford (2006), were identified in the study area and phytosociologically described. Six plant communities and two subcommunities were identified. Multivariate statistical analyses (correspondence analyses) confirmed that the species composition of these areas corresponds with and does therefore form part of the Norite Koppies Bushveld vegetation type as described by Mucina Rutherford (2006). Some of these communities contain Boscia albitrunca, a protected plant species, and should therefore be considered as areas with conservation value.

At a platinum mining company, the research was based on the root cause analysis technique. The objective was to determine the major causes of failure of the pebble crusher, to estimate between the major crusher failures and provide suitable solutions that included the optimization of the crushing circuit. Major failures were investigated including the breaking of the main shaft, bearing failure, and also entry of tramp iron in the crushing chamber. In solving these problems, analysis of stresses was done using solid works 2015, and condition monitoring techniques were applied using MATLAB 2015 to investigate the development of the crack in the shaft. The results showed that EN 19 has better physical properties than EN 9 and EN 26. EN 19 was recommended for the construction of the main shaft. Crack detection prediction by using MATLAB can be complemented and validated by the use of non-destructive testing.
