Applied Mineralogy: Luminescence Applied to Gems and Ore Minerals

Presenters: Adrian Finch (University of St Andrews) and Richard Shaw (British Geological Survey)

Date: Friday, August 25, 2023

Luminescence is a powerful mineralogical tool that encodes the geochemistry and growth history of minerals, including those in ore deposits. It is also an important aspect in the identification and value of gems. The purpose of this short course is to take participants through the fundamentals and practical applications of luminescence phenomena in mineral systems. We will include the fundamentals of the luminescence, particularly, Ultra-Violet Fluorescence and cathodoluminescence which are the most widely used methods. The course will include both petrographic and spectroscopic analysis of the data.

Critical Minerals: Geological Perspectives for Discovery and Recovery

Presenters: Richard Herrington, Robin Armstrong, Francesco Putzolu, and Reimar Seltmann (Natural History Museum); Kathryn Goodenough (British Geological Survey); Steve Roberts (University of Southampton); Frances Wall (University of Exeter); Maria Boni (University of Naples); and Anthony Williams-Jones (McGill University)

Date: Friday, August 25, 2023

Digital and low carbon technologies use a huge array of ingredients, and these days geologists need to know about ore deposits of the majority of the elements in the Periodic Table. Many of the specialist elements that make our technologies work are critical minerals. A cast of guest speakers will introduce the concept and challenges of criticality and discuss key aspects of the mineral system, exploration techniques, and process mineralogy for their favorite critical minerals, including vanadium and scandium as well as the more "usual suspects" — lithium, cobalt, and rare earths.

Structure and Diversity of Orogenic Gold Deposits

Presenters: Dave Rhys (Consulting Geologist), Stephen Cox (Australian National University), Richard Goldfarb (Independent Consultant), and François Robert (Independent Consultant)

Date: Friday, August 25 - Saturday, August 26, 2023

This course will review the style, structure and setting of orogenic gold and related deposits, which are the most prolific sources of primary gold production globally from both Precambrian and Phanerozoic metamorphic belts. Structural controls on fluid flow, vein formation, deposit localization, structural architecture, and the effects of progressive deformation on orogenic gold deposits and districts will be reviewed. We will also address the diversity of deposit styles in metamorphic belts, including variations in orogenic gold styles (e.g., iron formation-hosted gold deposits, disseminated versus vein styles), early and/or atypical deposits in Precambrian belts, and the relationships with intrusion-associated deposits.

Environment, Social, and Governance (ESG) Across the Mining Industry

Presenters: Sarah Gordon and Rose Clarke (Satarla)

Date: Saturday, August 26, 2023

Environment, Social, and Governance (ESG) is rapidly increasing in importance. Customers, investors, regulators, operators, service providers, academics, potential employees, and others are paying more attention to how and from where raw materials are obtained. ESG factors need to be considered from the very beginning, and as "the first boots on the ground," geos involved in exploration have the responsibility to ensure that this is the case. Throughout the whole mining value chain, geologists and earth scientists are also uniquely placed to address and improve ESG. In this interactive workshop, we examine the importance of ESG during exploration and mining, and discuss the roles and responsibilities of geoscientists and exploration/mining companies, as well as professional bodies, nongovernmental organizations, investors, procurement specialists, and society.

Why Bother with Geophysics? Adding Value Rather Than Wasting Time

Presenter: Tim Archer (Reid Geophysics)

Date: Saturday, August 26, 2023

A range of geophysical techniques exist for exploring the subsurface. But unless they are properly designed, geophysical surveys often provide inconclusive results and fail to add genuine value to commercial exploration programs. In this workshop, and based on more than 40 years of academic and industry experience, we investigate why geophysical surveys go wrong, briefly summarize available techniques—including what is state-of-the-art, and demonstrate by means of real-world examples how thoughtful geophysics can greatly enhance technical and commercial project outcomes.

Post-Conference Workshops

All workshops are in person. Details are still being finalized, and exact dates/times are preliminary and subject to change. Registration is expected to open in early 2023.

Let's Talk Core Logging and Hit the Reset Button!

Presenter: John Orpen (Resource Exploration & Development Pty Ltd)

Date: Wednesday, August 30, 2023

The diamond driller's task is to acquire good core recoveries from accurately depth-registered drill runs that are oriented, if required, from a borehole that is kept on course to target. Although we are good at mapping features in outcrop, we are generally lousy at enumerating the measurement uncertainties with which subsurface data are located – determining the volume of the "displacement uncertainty ellipsoid" within which there is a 68% probability that a feature logged will be found. The workshop examines the errors affecting the ellipsoid's depth, inclination, and azimuth axes and reviews the effects of the other random, systematic and human errors found during QA/QC of the drilling and logging processes.

Life Cycle Assessment to Explore for Low Carbon Mines

Presenter: Robert Pell (Minviro)

Date: Wednesday, August 30, 2023

Life Cycle Assessment (LCA) has become the standard tool to quantify environmental impacts of production, manufacturing, and indeed the whole cycle of use and re-use of products and materials. It can be applied not only to working mines but is a powerful tool during exploration from about pre-feasibility stage onwards to determine the impacts of the proposed mine, and thus identify the main challenges and actions that will reduce the future impacts. The course will introduce the LCA technique to exploration geologists and illustrate its use with case studies.

Resource Estimation and Pit Optimization Masterclass

Presenters: Tom Pratelli and Lais Hirata (Micromine)

Date: Wednesday, August 30, 2023

Tom Pratelli and Lais Hirata will review some of the latest improvements to be incorporated into resource estimation over the last few years. Topics will touch upon the use of dynamic anisotropy and how this can improve estimation, the use, and advantages of using neural networks to improve estimation and how top cutting can be superseded by thresholding. Working examples to demonstrate how these methods are employed will be shown.

The Role of Resource and Reserve Classification and Reporting in Financing the Supply of Critical Minerals

Presenters: Edmund Sides (PERC), Mark Burnett (AMC Consultants), and Brock Salier (Sprott Capital Partners)

Date: Thursday, August 31, 2023

This workshop will provide an overview of the different systems that have developed for the classification and reporting of mineral resources and reserves. The difference between the CRIRSCO (Committee for Mineral Reserves International Reporting Standards) systems which are used for Stock Market disclosure and the UNFC (United Nations Framework Classification) based systems which are designed to support governmental strategic planning will be explained. Case studies of reporting and development of fundraising for critical minerals will be examined.

How to Discover, Drill Out, and Mine a Porphyry Au-Cu Deposit

Presenters: Dan Wood (University of Queensland) and Andre van As (Van As Geotechnical)

Date: Thursday, August 31, 2023

The workshop will cover a detailed discovery history of the Cadia Au-Cu porphyry deposits and development of a hypothetical porphyry exploration program, discovery drilling through to deposit delineation and resource definition, and the mining of a porphyry deposit with a focus on underground cave mining and the geotechnical parameters required to inform cave mine design and cave mine operations.
