Fit-for-Purpose Geochemistry and Fewer Bad Programs with Simon Bolster

00:00 / 1:16:08

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
