This week Kyle Eastman will discuss Montana’s critical minerals resources and provide an update on current MBMG/USGS geologic mapping, geochemistry, and airborne geophysical survey projects. The Montana Bureau of Mines and Geology is actively involved in generating new pre-competitive maps and data that support exploration in Montana, and this talk will provide a state survey perspective on critical minerals research. Come along this Wednesday 18th September 11am AEST / 17th 7pm MDT Register now: https://geohug.rocks/

Dr Andrew Heap, Chief of the Minerals, Energy and Groundwater Division at Geoscience Australia, will be joining us to discuss the impact the world-leading geoscience delivered through the remarkable Exploring for the Future program led by Geoscience Australia. Dr Heap will share some of the key highlights from this impactful eight-year program and demonstrate its benefits, achievements and legacy. You will hear how over the course of the program Geoscience Australia has:  - Flown over 400,000 line km of airborne geophysics  - Collected over 215,000 ground geophysical data points  - Analysed over 46,000 soil, rock, and water samples  - Characterised over 124 million mineral grains  - Completed 21 km of mineral, energy, and groundwater stratigraphic drilling  - Released over 1,000 new datasets and publications  - Added more than 9.6 million data points to the Data Discovery Portal. We'll hear how the Exploring for the Future Program inspired and underpins the landmark precompetitive geoscience initiative, Resourcing Australia’s Prosperity. Dr Heap’s presentation will provide an overview of the new Resourcing Australia's Led by Geoscience Australia, this $3.4 billion investment over 35 years is designed to position Australia as a global renewable energy leader while striving for net zero emissions by 2050. In delivering this landmark initiative, Geoscience Australia will map the critical minerals and strategic materials, low emissions energy and groundwater resources needed to support our future prosperity.

Count down is on for Carl Spandler to join us in the hot seat as he guides us through his current research on understanding how, where and when ore deposits of critical metals, such as the rare earth elements, are formed in the Australian continent. By using petrology and geochemistry to research the evolution of the Earth’s crust and mantle, and the formation of metalliferous ore deposits we'll get to hear about how novel in-situ geochronology methods applied to ore deposits are a game changer for resolving the temporal evolution of mineralisation systems.

The vast majority of mineral deposit models for sediment-hosted metals either assume random “blob-like” ore geometries or laterally-continuous sheets. Incorrect mapping of ore-bodies based on these models leads to errors in resource modeling and dilution during extraction. Permeability in sedimentary systems is controlled by facies, diagenesis and mechanical stratigraphy. Regardless of temperature, redox state, or pH, mineralizing fluids will always take the path of least resistance. These points are highlighted in this week's session with Ali Jaffri, Ph.D. using examples of Sediment-hosted Stratiform Copper (SSC), Sandstone-hosted Vanadium, Carbonate-hosted Uranium, and Carbonate Replacement Deposits (CRDs). The goal for this week is for you to appreciate the complexity of host-rock stratigraphic architecture and why it is a detail that cannot be overlooked when exploring for sediment-hosted metals. So come and join the fun this Wednesday 31st 11am AEST/ Tuesday 30th 6pm MST. Register here: https://geohug.rocks/

Time-Space Evolution Of The South West African Craton! Curious about how ancient earth processes shape mineral-rich provinces? Join us for this week's geohug session as Nicolas Thebaud guides us through the latest research combining lithogeochemical data and radiogenic isotopic analyses (U-Pb, Lu-Hf) on zircons. This integrated approach reveals the 4D evolution of the lithosphere in Guinea, Liberia, and Sierra Leone, highlighting: 🔸 The presence and reworking of ancient meso- to paleo-Archean lithosphere. 🔸 The magmatic evolution from 2300 Ma to 2040 Ma, showcasing juvenile material input and significant crustal reworking during the Eburnean progeny. 🔸 Insights into the crustal and metallogenic evolution that shaped today's mineral endowment. Join us this Wednesday 24th July 4pm AEST to see how these ancient processes influence modern mineral exploration and the geodynamic evolution of the SWAC. Register here: https://geohug.rocks/

Mineral exploration suffers from a prediction problem: we are good at predicting mineralization, but not very good at predicting world-class mineral systems. Prospectivity models take months to build, geoscientists are under considerable cognitive load, and few techniques are used to stress test our understanding of how critical processes need to line up for world class mineral systems to form. AI has the potential to drastically improve our predictive capability, but issues like those discussed in the article below are raising legitimate concerns. BHP is committed to the advanced application of emerging technology and in this week's session Nicole Januszczak P.Geo, Ph.D. will share how they are preparing to use AI at scale and at pace to accelerate the delivery of high value options to the business. https://lnkd.in/eUNk2V_c Come along to hear all about it this Wednesday 24th July 11am AEST Register here: https://geohug.rocks/

Identifying rock types and geological processes from whole rock (4 acid digest, ICP) analyses. It is really difficult to consistently log drill core from highly altered rocks within a group of geologists with different levels of skill and experience. This week's session with Scott Halley is going to be a live demonstration (what could possibly go wrong) in ioGAS using geochemical data integrated with logged rock types, to make a more consistent geological interpretation.

Joining us this week, Anna Fonseca, MSc, PGeo will be chatting to us about Emerging Asia Metallogenic Belts. Anna has over 30 years of international experience in regional to property scale structural and alteration geology mapping and 3D modelling, interpretations of remote sensing data in mine to greenfields exploration stage and various hydrothermal deposit styles with a focus on porphyry-epithermal, carbonate replacement, skarn, and IOCG styles of mineralization. She has been based in Kazakhstan since 2019, and has taught field and classroom based structural and alteration mapping courses in university, in conferences, and in industry. This is going to be a goodie! This Wednesday 11am AEST. Register here: https://geohug.rocks/

What is a variogram? If you are in need of a refresher then this is the presentation for you! Gavin Clarkson introduced us to the foundational model of mineral estimation, he gave us an overview of what variograms are and shared some insightful visualizations. Check it out!

So, you’ve recently been appointed as an Exploration Manager - or you aspire to become an Exploration Manager. But what exactly does an Exploration Manager do? Where do you start and how do you prioritise? Nick Franey is joining us for this week's session where we'll cover everything from setting priorities and developing exploration strategies to managing drilling programs and understanding the importance of documentation. We'll dive into corporate deals, feasibility studies, and the essential role of data management. Plus, get insights on effective HR practices, health and safety management, and community engagement. Don’t miss out on this chance to enhance your skills and knowledge! This Wednesday 10th July 4pm AEST Register here: https://geohug.rocks/
