| 651-4034-00L | Resource Economics and Mineral Exploration  Block course 10 - 19 January 2022 at University of Geneva. Restricted participation with priority for MSc Earth Science students taking the Module 'Mineral Resources and Applied Mineralogy'. Interested ETH students please register through myStudies by second semester week. | 3 credits | 3P | G. Beaudoin, C. Chelle-Michou | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | Global mineral economics and the strategies of mineral exploration -- including geological, geochemical and geophysical methods, but also non-geological factors such as organisational, political and environmental aspects. Changing external lecturers. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Learning objective | Practical understanding of the procedure of exploring a mineral prospect, based on geological analysis, exploration by drilling, resource calculation of tonnage and grade as a basis for economic evaluation for reporting to investors. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | This block course in will comprise 4 half-day lectures and a series of practical exercises from selection of a mineral property to discovery of mineral resources and their valuation. Teams are formed as Limited Partnership companies that have to select and bid for a mineral property offered during an auction. Each company has the same nominal budget. The highest bidder purchases the selected property, others need to purchase the remaining properties during an auction. Justification for selecting the property is justified in a report. The companies must interpret the geology of their mineral property to prepare a diamond drill program to discover and, eventually, delineate the mineral resources. This drill program is presented in a report prior to drilling. Drilling in the tri-dimensional matrix of the property is simulated using the software FOREUR, until budget lapse. The companies must select drill intervals for chemical analysis to document the extent and composition of the discovered mineralization. Portions of the mineral rights can be traded for capital between the companies. An estimate of the tonnage and grade of the discovered resource is prepared using geometric methods and GIS software (ex. Arc GIS). The ground value of the resource is estimated by a computation of the Net Smelter Return at current metal prices. The results of the exploration program are presented in a comprehensive report. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lecture notes | Handouts for background information and a computer simulation program for the case-study exercise will be provided. Participants must bring a Windows-based laptop computer. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Prerequisites / Notice | Prerequisites: Knowledge of mineral deposit-type characteristics is useful (orogenic gold, Cu-Zn VMS, Ni-Cu-PGE); at least "Integrierte Erdsysteme", "Ore Deposit 1", or adequate knowledge of mineral deposits acquired by preparatory reading. Basic knowledge of ArcGIS software is important to produce maps and sections required in reports. Training exercises and tutorials will be provided in advance to prepare for the course.Taught biennially in collaboration with University of Geneva. This course is co-organised by ETH Zurich (Prof. C. Chelle-Michou) and University of Geneva (Prof. R. Moritz) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 651-4931-00L | Seminar I: Heat and Mass Transfers in Magmatology Does not take place this semester. | 1 credit | 1S | O. Bachmann, C. Chelle-Michou | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Abstract | Heat and mass transfers from the mantle to the crust control many aspects of the differentiation of our planet, including (1) primitive melt chemistry, (2) layering of the crust, (3) type of volcanic eruption, (4) formation of mineral deposits. This year, we will focus on processes in crystal mushes (formation, crystallization, remobilization, degassing). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Learning objective | This class will allow the students to learn about the modern methods and ideas on heat and mass transfers in magmatology through classic and recently published papers. Communication of scientific results to the scientific community and the public is critical. In the class, the students will read and analyse scientific papers and discuss them orally to the class. The students will also create a Wikipedia page and reformulate scientific results for the public. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Content | The class will focus mostly on 1) reading literature on topics of interests, 2) oral and written presentations of the papers, 3) exercises illusrating the topic, to allow students to work by themselves on some well-defined problems. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
