48. Big Data Wrangling for Core Sensing Technology

As our geo-toolkit expands, how can we equip ourselves to deal with these large volumes of highly diverse, dense data that are available and at higher speeds than ever before? This week’s episode is a companion to episode 47 (Core Sensing Technology) and host Britt Bluemel (Global Business Development Manager, ALS GoldSpot Discoveries) is joined by experts in the field of big data wrangling.   They discuss considerations when dealing with data from core sensing systems, with the aim of empowering geologists with better decision-making tools throughout the mining value chain.  New out this week is also a great paper in the SEG Discovery Magazine by Anthony Harris and co-authors - Empowering Geologists in the Exploration Process - Maximizing Data Use from Enabling Scanning Technologies.  Check it out for diagrams and case studies that demonstrate the use of core scanning technology.In this week's episode, our first guest, Dr. McLean Trott (Director, Ore Body Knowledge at ALS GoldSpot Discoveries) just completed his PhD on the topic of tackling big data and integration of various data streams, and how to extract the most value from datasets, including image data. Mac also discusses the utility of point measurement compared to line scanning or full core imaging, with an emphasis on fit-for-purpose data, while considering bottom line factors like speed and cost of data acquisition.  Next,  we’re joined by Dr. Jack Milton, VP Geology at Fireweed Metals, and he provides the ‘end user’ perspective. Fireweed Metals has used XRF core scanning technology for several years and Jack describes some of the key benefits and real time decision making that is enabled by this technology. Jack also discusses good connectivity for transferring these huge data files (their on-site scanner has its own dedicated Starlink system) and the necessity of high quality calibrations when collecting XRF data in the field.  Our final guest, Brenton Crawford (Datarock’s Chief Geoscientist) cautions us not just to choose the coolest machine, but to select the sensor that’s right for the job. He discusses utilizing scanning data to create geometallurgical domains, and how project success can be increased by including your IT team in the early stages of the conversation.  Next week, Anne Thompson will be back with three exceptional guests, to discuss the geology of lithium and explore three different host environments, brines, clays and pegmatites.Our theme music is Confluence, by Eastwinds.  Come join us in Salt Lake City, Utah for SEG 2026, September 30th to October 3rd. You can expect world-class technical content, including iconic ore deposits and the geological processes of North American Cordillera. The program balances applied case studies, framework geology, and technological innovation. The conference offers a unique opportunity to connect, learn, and help shape the future of economic geology. See you there.
