Book Synopsis An Integrated Risk Evaluation Model for Mineral Deposits by : Grant Nicholas

Available in PDF, EPUB and Kindle. Book excerpt: The core asset of most mining companies is its mineral resources and reserves. The company produces ore from its reserves, which is a subset of its mineral resources associated with varying levels of geoscientific confidence and uncertainty. One of the key evaluation challenges is to distil technical complexity into a financial model that is usually designed to focus only on one or two key valuation indicators, such as net present value (NPV) or internal rate of return (IRR). The driver behind this research was whether conventional evaluation techniques for mineral projects can evaluate accurately both the spatial and temporal characteristics of project risks in financial terms, due to their inherent nature to understate the true variance, and under-value or over-value the actual NPV. How can conventional evaluation methods be compared to an innovative, integrated evaluation technique that quantifies the non-linear impacts of spatial resource variables on production constraints in financial terms, measured at the appropriate temporal scale? To answer these questions, this research focused on developing an innovative risk evaluation methodology for two different diamond deposits and one gold deposit to incorporate spatial, non-spatial and financial data across the evaluation pipeline. The author developed an integrated evaluation modelling (IEM) framework based on a unique bottom-up methodology that follows every estimation block through the mining and processing value chain, i.e., it accurately captures the spatial variability of all relevant value chain variables in the ground and their correlated impacts on production constraints such as grade, density and processing characteristics. This variability is propagated through the processing value chain at a mining block (or selective mining unit, "SMU") scale. The IEM approach revealed differences in NPV between a 'bottom-up' (or Local) evaluation method and a 'top-down' (or Global) evaluation method - see Figure 1. While the actual NPV for the virtual ore body (VBod) was CAD 2.1 million, the figure shows that the local evaluation method (bottom-up) more closely approximated the actual NPV of the project than the global (top-down) evaluation method, which materially over-estimated the NPV. The author demonstrated that cash flow constituents derived from annual estimates in a top-down approach will not correctly reflect the asymmetries due to operational variability on a local, daily basis. The 'bottom-up' evaluation method represented a more accurate way of deriving annual cash flow estimates needed to make decisions on projects by accumulating the appropriate values from a bottom-up approach, i.e. daily, monthly, quarterly then derive annual estimates for NPV forecasts. The two main advantages of the IEM methodology are that firstly, it accurately reproduces the spatial resource characteristics of blocks at the appropriate temporal scale; and secondly, direct linkages are created between the resource-reserve-financial models within a single software environment. This allows multiple scenarios to be rapidly assessed for a mineral project and the cost/benefits of implementing risk mitigation strategies to be easily evaluated. This research also quantifies the financial impact of managerial flexibilities by evaluating selected hedging strategies that simultaneously consider production and economic uncertainties within an IEM framework. All modelled outputs are calculated in NPV terms using a modified DCF approach. The importance of linkages within an IEM framework is validated between unsystematic risks, with respect to key resource-to-reserve stochastic variables, and systematic risks considering the impact of foreign exchange rates. The author concludes that the greater the variability of key systematic and unsystematic variables, the more the mine has to consider flexibility in its mining and processing schedules and management hedging strategies; but the real costs of attaining that flexibility needs to be evaluated using an IEM framework. The confidence in a NPV estimate for complex mineral projects cannot easily be quantified using any closed-form analytical or mathematical solution. Complex, non-linear relationships between resources, reserves, financial and economic parameters requires a simulation model based on an IEM framework to provide a robust solution.

Book Synopsis Mineral Property Evaluation by : Richard L. Bullock
Download or read book Mineral Property Evaluation written by Richard L. Bullock and published by Society for Mining, Metallurgy & Exploration. This book was released on 2017-12-01 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Everything” sums up what must be considered for a properly documented property evaluation. Less than 30% of the projects that are developed in the minerals industry yield the return on investment that was projected from the project feasibility studies. The tools described in this handbook will greatly improve the probability of meeting your projections and minimizing project execution capital cost blowout that has become so prevalent in this industry in recent years. Mineral Property Evaluation provides guidelines to follow in performing mineral property feasibility and evaluation studies and due diligence, and in preparing proper documents for bankable presentations. It highlights the need for a consistent, systematic methodology in performing evaluation and feasibility work. The objective of a feasibility and evaluation study should be to assess the value of the undeveloped or developed mineral property and to convey these findings to the company that is considering applying technical and physical changes to bring the property into production of a mineral product. The analysis needs to determine the net present worth returned to the company for investing in these changes and to reach that decision point as early as possible and with the least amount of money spent on the evaluation study. All resources are not reserves, nor are all minerals an ore. The successful conclusion of any property evaluation depends on the development, work, and conclusions of the project team. The handbook has a diverse audience: • Professionals in the minerals industry that perform mineral property evaluations. • Companies that have mineral properties and perform mineral property feasibility studies and evaluations or are buying properties based on property evaluation. • Financial institutions, both domestic and overseas, that finance or raise capital for the minerals industry. • Consulting firms and architectural and engineering contractors that utilize mineral property feasibility studies and need standards to follow. • And probably the most important, the mining and geological engineering students and geology and economic geology students that need to learn the standards that they should follow throughout their careers.

Book Synopsis Minerals, Critical Minerals, and the U.S. Economy by : National Research Council
Download or read book Minerals, Critical Minerals, and the U.S. Economy written by National Research Council and published by National Academies Press. This book was released on 2008-03-11 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.

Book Synopsis Mineral Resources by : Manuel Bustillo Revuelta
Download or read book Mineral Resources written by Manuel Bustillo Revuelta and published by Springer. This book was released on 2017-08-23 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive textbook covers all major topics related to the utilization of mineral resources for human activities. It begins with general concepts like definitions of mineral resources, mineral resources and humans, recycling mineral resources, distribution of minerals resources across Earth, and international standards in mining, among others. Then it turns to a classification of mineral resources, covering the main types from a geological standpoint. The exploration of mineral resources is also treated, including geophysical methods of exploration, borehole geophysical logging, geochemical methods, drilling methods, and mineral deposit models in exploration. Further, the book addresses the evaluation of mineral resources, from sampling techniques to the economic evaluation of mining projects (i.e. types and density of sampling, mean grade definition and calculation, Sichel’s estimator, evaluation methods – classical and geostatistical, economic evaluation – NPV, IRR, and PP, estimation of risk, and software for evaluating mineral resources). It subsequently describes key mineral resource exploitation methods (open pit and underground mining) and the mineral processing required to obtain saleable products (crushing, grinding, sizing, ore separation, and concentrate dewatering, also with some text devoted to tailings dams). Lastly, the book discusses the environmental impact of mining, covering all the aspects of this very important topic, from the description of diverse impacts to the environmental impact assessment (EIA), which is essential in modern mining projects.
