Mining Engineering’s Post

Camborne School of Mines, University of Exeter alumni have been out in force again at the Society of Economic Geologists’ Resourcing the Green Transition event in London. Americans might host important mining events during bank holidays in the UK, but that hasn’t stopped various people who studied at CSM from turning up to walk the exhibits, take a look at the technical posters, and attend some of the numerous high quality presentations. For anyone who’s a member of the Camborne School of Mines Association and of a certain vintage, a highlight must be Alan Butcher presenting today. It is a small world when you meet your Igneous and Metamorphic Petrology lecturer for the first time in 26-27 years. The intervening years have taken me not only from upstream oil and gas exploration, to the wider energy value chain, but beyond to other industry sectors. I was relieved to hear Alan recommend Lawrence Robb’s excellent book, Introducing to Ore Forming Processes, as an effective way to compensate for my lapsed geological knowledge. Fortunately, I made that very wise purchase several months ago. In my experience, a willingness to learn and revisit subjects - be they markets, above ground risks such as those relating to geopolitics, or rocks - to boast your understanding is an ongoing commitment for anyone who wants to be an active member of the wider community in which they work. If that happens to be mineral exploration for you at this time, I - and it turns out Alan - recommend you take look at Lawrence’s book: #seg2023 #mineralexploration #geoscience #metals

Pan Global Resources Inc. (TSX.V:PGZ) Reports Near-Surface Copper-Tin Mineralization at Romana West, Spain. Pan Global’s president and CEO, Tim Moody, said “We are highly encouraged by the first two drill holes on the Romana West target, indicating a continuation of the near-surface copper and tin mineralization to the west of the La Romana discovery. From less than 50m below surface, sections of the drill core show visible copper (Cu) and tin (Sn) mineralization, including chalcocite, chalcopyrite, local coarse-grain cassiterite, and intervals of mixed massive sulphides.” Read more here: https://hubs.la/Q01WZsHZ0 #TSXV #PGZ

Join a free 30-minute webinar with Silvia Penna Misk, our Mineral Resource Consultant at Geovariances, to learn techniques for accurately estimating mineral resources in deformed geological environments. You will learn about: – Unfolding (or flattening) to come back to the situation during the time of deposition and restore the original continuity; – Local geostatistics that changes the orientation of the variogram model and neighborhood to follow the local main direction of continuity; – How Isatis.neo, Geovariances’ geostatistics software solution, makes applying any of these techniques easy. Its outstanding unfolding algorithm flattens even the most complex structures. #mining #geostatistics #webinar #unfolding

* How a basement fault has controlled Pb- Zn ore deposition within the Zagros Fold-Thrust Belt?: A focus on remote sensing approaches: https://lnkd.in/dJ3ynz9B ABSTRACT: The Zagros fold and thrust belt as one of the structurally complex areas have been considered chiefly only for hydrocarbon reserves, despite having other mineral deposits like the Surmeh lead and Zinc mine. This study was conducted in the Fars region, one of the structural zones in the Zagros, to detect hydrothermal alteration minerals associated with Pb–Zn mineralization and fracture distribution using ASTER, Landsat 8, and Sentinel 2 satellite imagery. Using different algorithms and approaches, we demonstrate the interesting distribution of Pb-Zn-related mineral deposits controlled by structures on different scales. These methods included the spectral band ratios and spectral angle mapping for alteration detection and manual extraction of structural lineaments (i.e. fault and fractures) from ETM+. Also, an augmented circular scanline method, along with areal sampling, was used to prepare a fracture intensity map of the area. According to the results, the intersection of NW-SE and N-S trending fracture sets are promising areas for Pb-Zn-related mineral exploration. These fracture sets are likely associated with the main Karebas tear fault and its horsetail splay terminal. The findings of this study were validated by field observation of the Pb-Zn deposit and its related mineral associations in the area.

Vektore’s new AR tool brings speed, accuracy, precision and universal reading of structures to the core shack Why are we still struggling to apply structural geology in target exploration and development? Aren’t the tools and required skills currently available in the industry sufficient for such an application? In 2023, we still see mineral exploration ventures […] Continue Reading → https://lnkd.in/di93N6dW

GOLD PROSPECTING METHOD: GOLD PANNING It should be realized that gold panning is perceived to be the most inexpensive and common technique for gold prospecting. Gold panning has been argued to be the most widely used and the oldest gold prospecting method. Gold pans are available in numerous sizes and shapes. The gold pans are built of plastic or metal. Figure 1 shows metal gold pans. Gold pans are applied in cleaning gold-bearing concentrates, gold prospecting, as well as hand working of isolated and rich deposits even though rarely. Hence, at the bottom of the gold pans heavy minerals are concentrated while at the top is where the lighter materials are removed to ensure that the basic operation of gold panning is simple. However, skills and experience are required to process huge amounts of materials which attaining maximum recovery. To appropriately learn the basic gold panning there is need to learn from a skilled and experienced gold panner. Source: Saliou, B. and Huang, X.

Taiton Resources Limited (ASX:T88) has initiated an UltraFine (UF) soil sampling program on its journey to better understand the geological nature of its Highway Project in the resource-rich Gawler Craton of South Australia. The survey aims to uncover the geochemical signatures of prospective hydrothermal targets cost-effectively over a large area with a full suite of elements, including #molybdenum, base metals and rare earth elements to be analysed. This data will be vital to the company’s strategic approach and long-term trajectory, as it will offer a detailed view of the site’s mineral composition.

Litchfield Minerals Limited (ASX:LMS) is pleased to announce that, following the March 2024 IP survey, which was conducted at the Wolfram Hill Prospect at Mount Doreen EL 31305, new targets have been identified. The survey indicates potential for extensions to the north and south of known mineralised reefs at depth and along the strike. To assist, a summary of the geological context for Wolfram Hill is provided at the end of this announcement. Matthew Pustahya, Managing Director, commented on the success of our IP campaign and the potential of bismuth: “Since our debut on the ASX, only two weeks ago, we've launched a comprehensive work program and promptly mobilised Planetary Geophysics to Mount Doreen for an IP survey across the Wolfram Hill Prospect. The initial data we've gathered is looking exceptional. Planetary Geophysics will continue the survey as soon as weather conditions permit, ensuring safety and precision.” “The March IP survey at Wolfram Hill has been remarkably successful, filling us with confidence about the significant drill targets we're poised to explore in the upcoming period. This momentum propels us forward, as we anticipate revealing the full potential of these promising findings.” “Bismuth is such a rare element, with an average concentration of about 0.2 parts per million (ppm) in the earth’s crust. This scarcity places it on a par with precious metals like gold and silver in terms of abundance. We are excited because not only is bismuth rare and part of Australia’s, Europe’s and the United States critical mineral lists, it’s a great indicator for gold, especially in the Tanami region of Central Australia.” “We are still eagerly waiting and ready for tracks to dry in the back country after an unprecedented rain event that took place in March. We aim to start our initial drill program at Silver King once the station gives us the go ahead.” Read more: https://lnkd.in/gU58555N

Choosing the best geophysical method for your target can be puzzling since:  - Not all deposits are created equal  - Not all geological conditions are the same across a deposit type  - Not everything responds well to geophysics At Abitibi Geophysics, we recommend running Physical Property tests on available samples to better understand your target and surrounding to help in taking informed decisions about mineral exploration or mining operations.

If you have an exploration project or mine in the USA, I could generate high-resolution images (0.5-1.0 m pixel size) from free public domain spectral data (visible and Near-infrared bands), which would usually be very expensive to acquire. These images could be part of the package of images that I usually process for RSG projects, or they could also be part of a project aimed only at generating this type of imagery as a base for field reconnaissance or detailed geological mapping at the project scale. So feel free to contact me in my LinkedIn inbox for more info and/or send me your request for a quote for your project. The image/example below is a zoom of the larger image processed with the high-resolution data indicated above that I recently posted. This corresponds to the world-class Cu-Au-Mo mine of Porphyry Copper with associated Skarn in Utah, USA, which post and all related info and details you can review in the link below: https://lnkd.in/d78ktUm7 Rodrigo Díaz Principal Geoscientist-Manager & Technical-Strategic Adviser Global RSG - Remote Spectral Geology Consultancy in Economic Geology - Base, Precious & Strategic Metals #MineralExploration / #GlobalRSG_PorphyryCopperDeposits / #Copper / #Gold / #Mining Please click on the high-resolution RSG image/zoom in the comments section for better visualization. Then by clicking the mouse right button on the image (save images as), you can download it and see the image with even better resolution in your preferred image viewer software.
