Beyond the Big 3 Metallogeny of the Humboldt Range SEG Forum: Carlin-Like Gold Deposits: What Can We Learn Beyond The Known Trends and Nevada? The tradition of examining Carlin controversies in a pre-meeting forum was born 10 years ago with a debate over magmatic vs. amagmatic origins for these deposits. In this forum, we will start with what we know about the large Carlin-type deposits in Nevada, and looking outward at Carlin-like deposits elsewhere in the Great Basin, Yukon, China and other locations. Do these Carlin-like deposits have different origins or do they form a continuum with the deposits in Nevada? Come participate in the discussion!

Rehrig 8 benefits and drawbacks of the various methods. The emphasis will be on core and reverse circulation drilling but will also introduce methods currently applied to water wells, geotechnical and environmental studies, and hydrocarbons. Topics will include types of samples obtained, relative costs, environmental foot print, getting the most information out of the hole, and basics of drill contracts. A section will also be devoted to the hydraulic fracturing process used in the petroleum and water well industries. A further goal of the class is to provide “cross pollination” between drilling companies and the broader geoscience community to enhance innovation and reduce costs. This class will be a mix of classroom lectures and field experiences with the drilling equipment. This course is built around SEG Special Publication #3, which was designed as a workbook to be used in conjunction with the 2 or 3 day short course, this will be a 2 day course. As co-authors, John Stone and Peter Dunn have spent most of their professional careers in the mineral industry. Both had come to the conclusion that the reserve estimates that had formed the basis for a very large percentage of the actual mining operations with which they were either familiar or aware of, were either wrong, or at best misleading. Furthermore, while the tonnage of ore produced by a given operation was often greater than the tonnage originally forecast, the grade of ore (and hence the profitability of the operation) was almost invariably lower than envisioned by the feasibility study leading to final project approval. In short, studies were almost always wrong, and generally only in the least favorable direction. Since many of the examples within the course are based on actual cost sheets from actual operations that are no longer in operation, we elected not to artificially inflate cost numbers and commodity prices. $350/oz gold may seem like a quaint anachronism, but was quite real in the mid-90s! In order to observe drill rigs in their native environment, this class will be based in Elko, Nevada. Attendees will need to bring their own PPE (hard hat, glasses, steel toes, and ear protection). The cost of the course includes class materials, lunches, snacks and local transportation. Participants will need to make their own travel and lodging arrangements. SC3 Modern Drilling Fluids: The Software The text itself (and the short course), is broken into the 10 chapters, covering the basic economic concepts used in the analysis of a projected mining venture (cash flow, selective mining, cutoff grades, etc.), the various methods for projecting the tiny fraction of a deposit actually sampled into the vast unknown space surrounding a given sample site, the estimation of the geometry or volume of the deposit, the density or tonnage factor, the distribution of grade values, and the location in 3-D space of the deposit and its influence on mining dilution. The last three chapters are on mapping, sampling, mine grade control and “Theory vs. Reality”. At the conclusion of each of the main chapters, there are a couple of simple exercises designed to illustrate the various points raised in the preceding chapter. The text IS NOT a course in geostatistics, or any particular method of reserve estimation, but is rather a review of the applicability and shortcomings of the various methods commonly in use. May 15-16, 2015 Instructor: Baroid Industrial Drilling Products Cost: Student $100, Technical Session Registrant $450, NonTechnical Session Registrant $550 Participants: 6 minimum, No maximum This course is custom designed with the mining industry professional in mind. The course can be paired with the Modern Drilling Systems class to form a comprehensive four day course focused on the drill site and managing sample control. Participants could include geoscientists, environmental specialists, regulatory agencies, drilling professionals and support staff. This two day course will cover the application of modern drilling fluids and maximizing hole control, sample quality, penetration rates and overall project costing. SC2 Modern Drilling Systems: The Hardware May 13-14, 2015 Instructor: Boart Longyear Course Description: In mineral exploration and development drilling, there is nothing that affects recovery and quality condition of the sample obtained more than that material’s interaction with a drilling fluid. A stable drill hole provides us the “pathway” to obtaining a drill sample from the desired zone. In the drilling process, the composition and movement of a drilling fluid is one of the principal real-time adjustable parameters that can affect the complete recovery of a high quality representative sample (either chips or core) and also affect the stability of the drill hole. This two day seminar will provide a state of the art view of the technical side of what comprises a drilling fluid, what properties and functions are desirable and possible, limitations which may exist, and which fluid types are appropriate for drilling in different geologic conditions. The course will discuss common fluid types used in air drilling (RC and conventional), as well as coring and mud rotary applications. The course will also provide an overview of global trends in the evolution of drilling fluid use, including the environmental implications of drilling fluids, the logistics involved and global industry trends. The course will be immediately useful to exploration Cost: Student $25, Technical Session Registrant $195, NonTechnical Session Registrant $195 Participants: 6 minimum, No maximum This course is custom designed with the mining industry professional in mind. The course can be paired with the Modern Drilling Fluids class to form a comprehensive four day course focused on the drill site and managing sample control. Participants could include geoscientists, environmental specialists, regulatory agencies, drilling professionals and support staff. This two day course will cover the application of modern drilling fluids and maximizing hole control, sample quality, penetration rates and overall project costing. This class is an introduction to obtaining subsurface information by drilling. All drilling methods involve tradeoffs between sample quality and cost. This course will cover the 9 geologists, drilling contractors and other personnel responsible for the planning and management of mineral exploration drilling programs. Lecture topics include: geological settings and controls on mineralization, hydrothermal minerals and their zonation, precious-metal transport and deposition, spatial and temporal scales of mineralizing processes, and case studies. Emphasis is placed on understanding the exploration potential of a project and the depth-level of erosion. In order to observe drill rigs in their native environment, this class will be based in Elko, Nevada. Attendees will need to bring their own PPE (hard hat, glasses, steel toes, and ear protection). The cost of the course includes class materials, lunches, snacks and local transportation. Participants will need to make their own travel and lodging arrangements. Comstock Lode Field Trip (May 23) — The Comstock district, in the southern Virginia Range of western Nevada, is hosted by Oligocene-Miocene volcanic and intrusive rocks. Several different phases of hydrothermal activity have produced a spectrum of alteration styles associated with quartz-alunitepyrophyllite-diaspore and quartz-adularia-illite-calcite assemblages, plus silver-rich bonanza vein ores containing quartz, adularia, and calcite. Field stops through the district provide an overview of the geology, alteration and vein fill that is typical of epithermal mineralization and that will stimulate discussion of hydrothermal processes and depth level controls contributing to ore genesis. SC4 Great Basin and Cordillera Mining Geophysics May 16, 2015 Instructors: Various Cost: Student $50, Technical Session Registrant $225, NonTechnical Session Registrant $350 Participants: 9 minimum, No maximum The success of the First Great Basin and Western Cordillera Mining Geophysics Symposium was reflected in the attendance of over 100 participants in Elko in 2013. EGG and GSN would like to extend an invitation to the second biennial symposium which has been integrated into the 2015 GSN Symposium in Reno as a pre-meeting Short Course. The oneday event will showcase geophysical case studies and recent technical advances in mining geophysical applications. SC7 Analytical Methods in Geochemistry May 17, 2015 Instructors: Sarah Rice (ALS Geochemistry), Lynda Bloom (Analytical Solutions Ltd.), Phil Allen (Consultant), Shea Clark Smith (MEG Inc.), Jeff Jaacks (Geochemical Applications Intl.), Pim van Geffen (Reflex Geochemistry) Cost: Student $50, Technical Session Registrant $225, Non-Technical Session Registrant $350 Participants: 10 minimum, No maximum This is the second biennial offering of the extremely well received program organized by the Elko Chapter of GSN. Geophysicists, geophysical service providers, geologists and engineers are all encouraged and welcome. This offering is designed to focus on practical application of modern geophysical techniques, with an emphasis on case histories of sediment-hosted, porphyry and epithermal deposits and successful application of technology in the increasingly crossdisciplinary world of mineral exploration. How your geochemical data is generated, and is it fit for purpose? It’s an all-important question in our current exploration and mining environment of tight margins, low risk appetite and NI 43-101 requirements. But many geoscientists order up assays and later receive the results without really understanding the mechanics behind the “black box” that produces them. This course can be paired with the Applied Geochemistry in Mineral Exploration, Development and Environmental Monitoring class to form a comprehensive two day course focused on applied exploration tools using real world case studies. This course will help you understand and leverage the huge selection of analytical methods available to best suit your needs, whether you’re working in greenfields exploration, resource estimation, or grade control. Presentations by leading geochemists with over 100 years of combined experience will cover the most important considerations behind picking the right analytical methods for your project and getting quality data out of them. We’ll cap off with a surficial sampling case study over blind mineralization comparing many geochemical techniques. SC6 Epithermal Deposits: Characteristics and Processes May 21-23, 2015 Instructors: Stuart Simmons and Donald Hudson Cost: Student $125, Technical Session Registrant $575, NonTechnical Session Registrant $700 Participants: 17 minimum, 42 maximum Bring your thinking cap, there will be pop quizzes! Short Course 6 will consist of a 2-day lecture and a 1day field trip. Course Outline 1. Lecture Content (May 21-22) — Epithermal deposits are diverse and attractive exploration targets for gold and silver because they can contain high grade ore and large metal inventories, and they can overlie deep porphyry mineralization. This course focuses on the geological characteristics of epithermal deposits, their hydrothermal mineral patterns, and the processes that produce them. 2. 3. 4. 5. 10 Overview of sample preparation and geochemical analysis: how to pick your methods (Sarah Rice & Lynda Bloom) Quality control in exploration (Phil Allen) Portable XRF and data quality (Pim van Geffen) Exploration with biogeochemistry (Clark Smith) Case study: surficial sampling program with various geochemical techniques (Jeff Jaacks) SC8 Geometallurgy: Applied Metallurgy for Geologists SC9 Leapfrog Modeling for Exploration and Development May 21-22, 2015 Instructors: Various May 21-22, 2015 Instructors: Leapfrog Metallurgy is usually viewed as a follow-on step to successful discovery of potentially economic mineralization, and is cross-disciplinary knowledge that most geoscientists gain indirectly through experience on development projects. Metallurgy is ultimately used to determine what the raw assay data being generated on a project might mean in terms of economics. Knowing more about the downstream processes that might be utilized to recover metals or minerals leads to better informed decisions at every step of the project pipeline. LeapFrog Geo is a three dimensional geologic modeling and data presentation program that bridges the gap between simple cross sectional data presentations and full-blown reserve estimation and mine planning software. Imagine taking your raw drill hole data and being able to validate, visualize, analyze, and start modeling within 30 minutes! No set up or digitization. Leapfrog Software lets you build models in minutes or hours, rather than days and weeks of work. Leapfrog is an easy-to-learn indispensable tool for front-end 3D visualization and rapid analysis of data (geology, geochemistry, metallurgy, geophysics, structure, etc.) that is being used for analysis and targeting in grass roots exploration, building 3D models for rapid assessment. Please note that space will be limited. To avoid disappointment, please get your application in early. This is a mini-session about ½ the duration of a full Leapfrog Fundamentals course.

Most organizations derive only a fraction of their data’s potential value due to limited data analysis and interpretation tools. This is because tools such as GIS packages and Excel spreadsheets are not specifically designed for analyzing exploratory geochemical data. They are time consuming to use and may end up compromising the quality of the interpretation by limiting how you view your data. IoGAS has been specially developed for exploratory and geochemical data analysis. It offers the best tools and workflows for efficiently interpreting your data by capturing the experience and knowledge of the REFLEX Geochemistry (formerly IoGlobal Consulting) team of world-class geochemists. The following data are commonly used for geometallurgical modeling (modified from Wikipedia): Assay information Alteration mapping Quantitative and qualitative mineralogy Bond ball mill work index test Modified or comparative Bond ball mill index Bond rod mill work index and Bond low energy impact crushing work index SAG Design test SMC test JK drop-weight test Point load index test Sag Power Index test MFT test FKT, SKT, and SKT-WS tests Through the IoGAS dynamic graphical environment, you can interact with the data in real time, making it effortless for you to detect patterns, anomalies, and relationships across your data. Combined with optimized workflows, you can produce high-quality interpretive outputs with the confidence that you have applied best practice as developed by a team of geochemical experts. Just as importantly, these results can be produced in a fraction of the time taken by traditional tools. IoGAS is a powerful statistical and mapping program designed specifically for the interpretation and presentation of geochemical and geologic information. 11 SC11 Paper to Electrons: Practical GIS for Geoscientists Turquoise Ridge, Cortez Hills, Gold Quarry, Emigrant. What are the classic features of this important class of gold deposits? And what features are unique to individual deposits? Find out by visiting four mines along three of the major trends of Carlin type deposits. This trip provides an introduction to Carlin deposits and the most recent geologic thoughts about them, appealing to both neophytes and seasoned Nevada geologists. May 22, 2015 Instructors: Robin Hendrickson and Alan Morris Cost: Student $50, Technical Session Registrant $225, NonTechnical Session Registrant $350 Participants: 9 minimum, No maximum Geographic Information Systems (GIS) are powerful tools to store, interpret, and present geologic information. As powerful as these tools are, they are only as useful as the data stored in them and the ability to utilize it. This course will focus on getting data from the field, core shed, and office into usable databases, use and maintenance of databases, and interpretative methods. This course is not about how to push the buttons on a specific GIS program but how to set up and utilize these systems efficiently. The target audience is anyone tasked with collecting, managing, or using GIS data.
