Brent Cook founded Exploration Insights in 2008 and has since transitioned into the role of senior adviser. As a seasoned geologist, Brent’s knowledge spans all areas of the mining business, from the conceptual stage to detailed technical and financial modeling related to mine development and production. He has worked in more than 60 countries and in virtually all geological environments, analyzing and providing commentary on proposed mine sites. Brent has also authored Geo-Insights, an instructive compendium of excerpts and geological explanations that he hopes will be a source of education for current and potential amateur investors doing their own due diligence. He also developed the Drill Hole Interval Calculator with Corebox. The calculator is an invaluable tool designed to provide investors with a means of estimating the grade of drill hole intervals between the “highlights” of a longer assay interval.
