Ben is a Superintendent of Resource Geology for Nevada Gold Mines, supporting Models & Modelers across the Carlin District. He received his Bachelor of Science in Geologic Engineering from the Colorado School of Mines. Ben began his career with KGHM as a geologic modeler, contributing to porphyry copper projects in Nevada, Chile, and Canada, and gaining experience in both near-mine exploration and production environments. He joined Barrick in the Cortez District as a resource geologist, where he focused on domain interpretation and estimation for the Goldrush and Fourmile projects through their prefeasibility stages. In his current role, Ben is dedicated to building geologically defensible models for Carlin-style gold deposits, emphasizing the importance of well-constrained, geologically informed domains as the foundation for high-quality resource estimates.

Oscar Rondon, FAusIMM, PhD is a skilled geostatistician and researcher with over 18 years of experience Oscar’s experience comprises Resource Estimation and applications of conditional simulation,Uniform Conditioning, change of support and non-linear techniques within a range of different commodities and mineralisation styles. Oscar has a strong theoretical background which combined with his working experience has also made him sought after for the customisation, development and presentation of geostatistical training courses worlwide.

Mr. Bertossi began his career as a mineral resources geologist in 2008 and has since developed strong expertise in geological interpretation, 3D modeling, and resource estimation. Over the last 3 years, he has been part of the team at the George Fisher Mine (GFM) in Queensland, focusing on integrating geological and grade control models for Glencore. He has worked in a variety of geological environments, including Cu-Co sedimentary deposits (Copperbelt, Africa), Nb/Ph alkaline-carbonatite complexes, Ni-Co/Al ultramafic complexes, Ni-Cu-Co (PGE) volcanogenic massive sulfides, Zn-Pb-Ag-Cu-Au VMS/SEDEX deposits, and limestone deposits. With an international career that includes Brazil, Canada, Gabon, the United States, the Democratic Republic of Congo, and most recently, Australia, Mr. Bertossi has gained practical experience in sampling, QA/QC, exploration/infill drilling, ore/grade control, and resource model-to-mine-to-plant reconciliations.

Elaine was born in Manila, Philippines, and earned a Bachelor of Science in Geology from the University of the Philippines in 2014. Early in her career, she gained valuable experience at Nickel Asia Corporation, where she contributed to a large-scale open-pit nickel operation and trained as a Resource Geologist. In 2018, Elaine relocated to Alaska, expanding her geologic expertise by working in both underground and open-pit gold mines with major operators, including Kinross Gold and Northern Star Resources. During this time, she demonstrated an exceptional dedication by completing a Master’s in Data Science from University of Denver, Colorado in just two years while working full-time. She also received formal academic training in Resource Estimation under Clayton Deutsch and earned a Citation in Applied Geostatistics from the University of Alberta. Elaine currently serves as a Senior Resource Geologist at Northern Star Resources, bringing over a decade of experience in geology and resource estimation. As a proud Filipino-American, Elaine is passionate about combining Data Science and Geology to drive innovation in the mining sector.
