Book Description
This fully updated textbook is intended for the economic geologist who deals with the evaluation of deposits at an early stage of development. It offers rules for quick and easy calculations based on the application of approximate data. It provides both the student and the geologist in the field with a complete set of rules and methods enabling them to perform a quick initial evaluation of the deposit without the support of specialists or computers – even if he is left to his own resources. All rules for calculations are illustrated with examples, and mistakes and pitfalls the authors encountered during their careers are pointed out.

Book Description
This textbook is a translation of the German textbook "Rechnen fUr Lagerstattenkundler und Rohstoffwirtschaftler, Teil 1" published by the Ellen Pilger Publishing Company. Those passages in the German edition which were especially written for the German readership were transform ed for English speaking readers. Compared with the German edition many chapters have been slightly amended. The main new additions in this English version are the chapter on linear optimization in Chapter 10.2 and Chapter 12 on the comparison of ore deposits. The textbook is intended for the economic geologist who deals with the evaluation of deposits at an early stage of development. Once an ex ploration project has reached the feasibility stage, the exact calculations of the deposit, the technical and economic assessment will be performed by a team of geologists, mining engineers, metallurgists, and economists. In the early stages of exploration, however, any evaluator of deposits has to be able to cover the whole spectrum himself. Since only order of magnitude parameters are available at this stage, the calculations can only yield order of magnitude results. Precise calculations would even be misleading, since the evaluation does not yet aim at accurate economic assessment but at making the right decision: should the investigation be abandoned or should it be continued at higher costs and with more detailed methods.

Book Description
Statistical evaluations of exploration data are the basis for decisions to be made at various stages of an exploration project. In contrast to other geostatistical books, Statistical Evaluations in Exploration for Mineral Deposits focuses not only on theory, but examples are also given, frequently originating from experience in mineral exploration by the author who worked worldwide for a mining company. Together with its companion volume, Economic Evaluations in Exploration, the book illustrates methods used in exploration campaigns and mining activities. It is intended as a vademecum for geologists who are forced to make quick decisions regarding an exploration project. It also addresses scientists and students involved in teaching or in mineral economic evaluations, recommendations or decisions.

Book Description
The past decade has seen increased attention to cost-effectiveness and benefit-cost analysis in education as administrators are being asked to accomplish more with the same or even fewer resources, philanthropists are keen to calculate their "return on investment" in social programs, and the general public is increasingly scrutinizing how resources are allocated to schools and colleges. This text (titled Cost-Effectiveness Analysis in its previous editions) is the only full-length book to provide readers with the step-by-step methods they need to plan and implement a benefit-cost analysis in education. The authors examine a range of issues, including how to identify, measure, and distribute costs; how to measure effectiveness, utility, and benefits; and how to incorporate cost evaluations into the decision-making process. The updates to the Third Edition reflect the considerable methodological development in the evaluation literature, and the greater empiricism practiced by education researchers, to help readers learn to apply more advanced methods to their own analyses. SAGE congratulates author Henry M. Levin, winner of the 2017 AERA Distinguished Contributions to Research in Education Award.

Book Description
“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 Description
How has exploration for minerals evolved in recent years? Is it as productive an activity as it once was? Why have changes occurred? Roderick G. Eggert explores these and other questions about the complex set of circumstances surrounding metallic mineral exploration. Originally published in 1987, Eggert documents trends in the level and the distribution of expenditures by mining companies for metallic mineral exploration and examines a number of factors that may be responsible for these trends. This significant study serves as a handy introduction to the subject for students interested in environmental studies, natural resources, and economics.

Book Description
Finding a new oil and gas discovery and evaluating its volume is a difficult and challenging task, and yet there is very little published on the topic. Luiz Amado delivers a one-of-a-kind introductory guide titled Reservoir Exploration and Appraisal. Providing logistical instruction and processes for the entire exploration and appraisal process, Amado furnishes the guidance, workflow, and practical recommendations needed based on real-world scenarios. Written by an engineer with over 15 years of experience in the North Sea, Gulf of Mexico, South America and West Africa, Reservoir Exploration and Appraisal equips engineers and economists with expert advice on critical subjects such as detailed methods of estimating recovery factors, creating production curves using either simple or complex approaches, understanding main fluid and rock properties that govern volume and productivity, and communicating examples of field case evaluations, including deepwater projects. Details methods of estimating recovery factors and rules of thumb that can be used if there is an absence of data How to create production curves using either simple or complex approaches Understanding main fluid and rock properties that govern volume and productivity, saving time from analyzing countless fluid samples or rock data from cores Describes the process of lease sales, bid rounds and farm-in opportunities Communicates examples of field case evaluations, including deepwater projects, to illustrate the steps covered in the book, showing the reader the full project cycle
