Sustainability of funding models used in Black Economic Empowerment transactions in the South African mining sectorNhasengo, Albert January 2016 (has links)
A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Engineering, 2016 / The purpose of this research is to identify and outline the sustainable funding models for BEE transactions in the South African mining industry. It is proposed that from the early 2000s to 2014 the sustainability of BEE funding models was driven by regulatory pressure. In the absence of regulatory pressure, there would be a need to develop alternative funding models.
The study uses a quantitative research methodology by examining the frequency of use of various funding models, the impact of regulatory interventions and use of various funding sources on the sustainability of funding models, regression analysis and significance testing.
The research results show that the percentage of third party finance in funding structures has a negative correlation with the success of BEE transactions. Vendor finance shows a positive correlation with the sustainability of transactions, more so above 60% in the funding structures. Equity finance has a positive impact on the success of transactions from as low as 20% in the funding structures.
An ideal funding structure would consist of the following funding sources:
Third party: Vendor: Equity = 40%: 20%: 40%, in the case of a BEE company that has equity available and
Third party: Vendor = <40%: > 60%, where no equity is available to BEE entrepreneurs.
In the absence of BEE laws third party finance will dominate funding of empowerment transactions. Funding models based on third party finance must rely more on cash flow based payments rather than dividend payments to service debt.

The governance of mineral resources in South Africa: the case of a selected mining community in Limpopo ProvinceApril, Funeka Yazini January 2017 (has links)
Thesis (Ph.D. (Public Administration)) -- University of Limpopo, 2017 / This study was undertaken in four villages which are Makgemeng, Maroga Phalatseng,
Mooihoek, and Legabeng, in the Limpopo Province. The aim of the study was to examine
whether local communities were benefitting from the local mine, whether the mine promoted an
acceptable number of LED projects; whether the mine complied with the Mineral Petroleum and
Resources Development Act 2002 (MPRDA), initiatives such as Black Economic Empowerment
and Social Labour Policies, and whether the mine helped the development of the local
economy, and whether the mine promoted job creation through down-streaming beneficiation
which is the core beneficiation form where a mineral is extracted, processed and sold as a
finished product and side streaming beneficiation which is an extended form of beneficiation
through infrastructures, roads, harbours, airports, railways, institutions
The study was anchored on the modernisation theory with a focus on the Sachs economic
stages. Four hundred participants took part in the study. The mixed methods research design
which integrates both quantitative and qualitative was applied since the study was aimed at
exploring and giving in-depth analysis of the relationship between mineral resource wealth
gained by the mining industry, and the ongoing poverty and marginalisation in the four rural
mining communities. Literature reviewed for the study establishes that despite mining
legislation, local economic development growth in rural mining communities remains
problematic due to lack of compliance of the Mining Charter which is a legislative instrument of
the MPRDA. South Africa has not managed to advance its state of manufacturing through
mineral beneficiation as it continues to export minerals partially processed thereby missing out
on the full economic value of job creation and industrialisation. Moreover, minimal
transformation amongst the Blacks in the rural mining communities has transpired as
envisioned under the MPRDA. Instead, an elite core of Blacks have broken into the mining
industry while a majority remain marginalised. It is argued that for South Africa to succeed in
promoting mineral industrialization through LED in rural communities, it will have to address the
challenges that rural typologies mining communities face which include challenges at municipal
capacity level, lack of policy alignment between local and national government, historical
mistrust between the mining industry and the community, spatial economics and minimal
business attraction. Globalisation it is argued can also be addressed better through the
modernization framework which promotes strong state intervention of legislative oversight.
Most industrialised states it is asserted reached the final economic stage of services through
iii
interventionist procedures unlike neoliberalism which promotes minimal state participation in
the business sector. Neoliberalism has been the bedrock of South Africa’s economic policies
since 1994. Due to neoliberalism, South Africa has been forced to take into consideration global
trends focused on increasing economic interdependence, and also constrained the ability of
South Africa’s ability to diversify its mining sector and communities.
The findings confirm that the Department of Mineral Resources (DMR) should create a program
that will serve as a one stop shop to provide mining information for the local government on
mining programs facilitated, and ensure that they are managed properly with the communities
involved. This program should also capacitate the local government officials in addressing
legislative oversight issues such as Social labour policies with the mines so that they don’t go
unchecked. Most of the community members perceived that the mine was not genuinely
interested in promoting the development of their communities, particularly in regards to LED
projects. The government also need to address the low literacy rate at the mining rural
communities which has become a roadblock for transformation. Industrialisation requires a
qualified human stock that would be able to professionally deliver on BEE related services and
development. For MPRDA to succeed as a beneficiation tool, it can only be accomplished
through human resource development beginning at basic education. Value-addition to minerals
is only achievable by a well-trained and fully equipped labour force
The study also confirmed that the mines were unwilling to engage with the communities, did not
understand the communities, were not transparent with them on tenders or procurements, and
made minimal effort to assist develop the communities. A majority of the mines did not
participate in the integrated development plan, and most of the community members indicated
that the mine did not view them as stakeholders. Lack of corporate social responsibility efforts
to alleviate poverty in the communities will only further tension and conflict within the
community. Moreover, this continued practice by the mines perpetuates lack of transformation
as required by the MPRDA leading the mining industry to remains predominately under the
control of white owned companies and rural communities to remain marginalized and
undeveloped. In summary, the DMR should stop relying on the mines to transform and comply
to all the MPRDA requirements without any form of effective oversight. / Human Science Research Council (HSRC)

Optimizing roof control using probabilistic techniques in roof failure predictionFraher, Richard Louis 06 October 2009 (has links)
A major objective in the design stage of an underground mine is the reliable prediction of roof falls' size, frequency and location. Probabilistic simulation of potential roof control problems allows a designer to test the performance of competing mine layouts against assumed roof conditions. By comparing different roof control plans using the simulation, the option that provides the lowest overall cost can be selected. The program ROCSIM (Roof control Optimization Cost Simulation) was developed to provide a theoretical solution to this problem. The occurrence and frequency of roof falls are related to the type of roof support, support density, geology, structural discontinuities, location in the mine, and elapsed time between mining and the roof fall. Using a Roof Rating System (RRS) developed for this research, a numerical rating can be given to each area of roof. Using this rating, specific parameters can be assigned to these probability distributions to simulate the occurrence of roof falls within a given geologic setting. Once the location of a roof fall is determined, a cost is calculated taking into account the production delay that would result and the direct cost of cleaning up the fall and resupporting the roof. Assigning a cost to a roof fall allows the comparison of competing roof support designs relative to their overall cost. The final decision on the amount of support and room width must be determined based on legal restraints and minimization of mining costs. / Master of Science

Enhancing the validity of the SAPS gold fingerprinting database through improved sample-collection techniquesCrundwell, Gordon Rhodes 30 April 2008 (has links)
This study's main focus was to analyse the methodology used by gold mines when obtaining reference samples required for gold fingerprinting analysis. Such methodology is also regulated by legislation in that in terms of the Precious Metals Act 37 of 2005 sect 22(1), "Any producer or any person who imports precious metals must submit to the Forensic Science Laboratory (FSL) of the South African Police Service (SAPS) such specimens of any precious metals produced or imported by him or her as may be prescribed". The gold mines are producers of precious metals, specifically gold, and they are therefore required to submit reference samples, which are then used by the SAPS FSL to maintain a database of gold samples. This database can then be used for comparison purposes during the forensic science of gold fingerprinting.
The supporting regulations of the Precious Metals Act, Section 19 stipulate seven requirements for the submission of reference samples and this study intends to give guidelines to security officials employed on the gold mines of South Africa to ensure that these requirements are met and that the validity of the SAPS gold fingerprint database is enhanced through improved sample-collection techniques.
The use of gold fingerprinting is part of the forensic investigation process used when trying to establish the origin of gold confiscated as an exhibit during police and mining security crime operations and recoveries, and this allows for victim identification in the resultant criminal trial and proper disposal of recovered gold-bearing materials that are recovered.
It is important for the mine security official responsible for reference sample collection to keep in mind that the methodology used when obtaining these samples could be challenged in court and that, therefore, definitive guidelines should be followed to ensure that the most representative samples are collected and that the collection and handing over of samples meet chain of evidence requirements. / Criminology / M.Tech (Forensic Investigation)

Accounting and taxation practices of selected mining exploration companies in South AfricaSturdy, Joline 30 June 2011 (has links)
The promulgation of the Mineral and Petroleum Resources Development Act 28 of 2002
(MPRDA) led to a significant increase in the number of junior exploration companies. In this
regard, International Financial Reporting Standard (IFRS) 6 allows companies to develop their
own accounting policies for exploration and evaluation expenditure. However, there is no
definition of either prospecting or exploration in the Income Tax Act 58 of 1962 (Income Tax
Act).
The objective of this study was to perform a literature review and to carry out empirical research
by using questionnaires that were distributed to junior exploration companies to investigate
whether accounting and taxation practices are consistently applied. Accordingly, the findings
confirmed that the accounting and taxation practices followed by junior exploration companies
are not consistently applied. / Financial Accounting / M.Com. (Accounting)

Development actors and the issues of acid mine drainage in the Vaal River systemNaidoo, Suvania 03 1900 (has links)
This study focuses on Acid Mine Drainage (AMD) in the three basins of the Witwatersrand’s goldfields in the Vaal River System in South Africa. AMD has become a highly contested issue. A difference in its definition exists between two groups of role-players identified in the study: government and consultants/activists/NGOs. This study unpacks the differences in the way AMD is defined, the situation of AMD in each of the three basins and the socio-economic implications caused by AMD. A crucial finding was that these definitions determine how the issue is understood and what solutions these role-players propose. The main purpose of the study was to determine whether the South African government’s policy response was appropriate given the socio-economic impacts of AMD and imperatives of sustainable development. This study concluded that, in the policy, there was no clear indication as to what the socio-economic impacts are, and limited attention was therefore given to these impacts. / Development Studies / M.A. (Development Studies)
