Paul Cordy, PhD
Based in Canada and Peru
Paul has spent the past decade working with small miners for myriad UN and development organizations with ASGM in Colombia, Peru, Congo, Kenya, Indonesia, Honduras, and many other countries. Through these experiences he has learned to apply practical small scale processing solutions, and to understand the challenges faced by gold miners, communities and governments globally. He also captures the challenges and solutions in ASGM in high quality video for integration into his mercury-free gold extraction educational video series. Paul earned his PhD at the University of British Columbia, studying atmospheric mercury emissions from artisanal and small scale gold shops: mapping, modeling, and mitigation. Paul’s aim is to develop practical alternatives to mercury use in artisanal and small scale gold mining that can reasonably be promoted by development agencies, particularly in the alluvial mining space. Paul hopes one day to be able to test his theory that residual gold can pay for landscape restoration in informally mined alluvial areas.
