Crystallex' Gordon Thompson's tenure was marked by difficulties at the Las Cristinas mine

Other notable resignations recently include that of Gordon Thompson of Crystallex, whose tenure at the helm of the struggling company was marked by difficulties in establishing the 17 million ounce Las Cristinas mine. Permits for the mine were rescinded by the Venezuelan Ministry of the Environment citing risk to the Imataca Forest Reserve. Management performance optimization is not the only cause for resignations.
