Every geoscientist is capable of understanding and applying geochemical data, however, at GeocHemiSTea we understand that there is an incredible amount of nuance and accumulated knowledge. We are here to break down the impediments towards geoscientists learning more about this exciting field! Are you a student wanting to break into the field? Listen to each episode to see how reknown geochemists got to where they are today. Are you intrigued by integrating geochemistry, but don't know how? Stay tuned!

Fit-for-Purpose Geochemistry and Fewer Bad Programs with Simon Bolster
Episode 2
Tuesday, 17 February, 2026
Simon Bolster joins GeOCHemISTea to unpack what actuallymakes near-surface geochemistry work in mineral exploration: understanding regolith and landforms before you ever “put dirt in bags.” With four decades in gold exploration, Simon argues that many programs fail not because geochemistry is “bad,” but because sampling and analytical choices do not match the terrain,the cover, or the project stage.The conversation moves from regolith terrain assessment andmapping as the real starting point, to why “lowest detection limit” is not a substitute for good planning. Simon also breaks down industry “silver bullets” (MMI, calcrete, ultrafines) and why blanket adoption creates false confidence. Finally, he explains how DetectOre upgrades gold from ppb-scale field chemistry into something actionable and fast, by leaching and concentrating gold onto a collector device that can be read by pXRF, enabling real-time decision-making while rigs are still turning.For this episode we read:Valuing time and how some of the latest technologies arecompressing time to fast track and de-risk new discoveries and mines (Bolster, 2025)
