Brent Cook is an economic geologist and mining analyst who has been involved in the minerals exploration and mining business for 40 years. During this time he has evaluated and valued grassroots through feasibility stage projects involving nearly all deposit types in over 60 countries. In 1997 he got tired of promoters making all the money on questionable properties while he was left standing soaking wet in the jungle and joined Rick Rule at Global Resource Investments (now Sprott-Global). He was principal mining analyst at Global until going independent again in 2002. Since then he has been an independent analyst and advisor to several investment funds and high net worth individuals. He is also the founder and senior advisor of the investment letter Exploration Insights which covers the mining sector, focusing on what the letter is buying, selling and avoiding.
