Mr. Andy Wallace is the principal of Cordex Exploration LLC ("Cordex"), considered by many in the mining industry to be one of the most successful gold exploration groups in the United States. Cordex was founded by the legendary John Livermore, who discovered the Carlin Mine in Nevada and a new type of gold mineralization that is now
referred to as "Carlin-Type". The discovery of the Carlin Mine transformed the gold mining industry in the United States and perhaps the world. A flurry of exploration for Carlin-Type gold deposits ensued and as additional discoveries were made, the Carlin Trend of Nevada became the most prolific goldfield in the Western Hemisphere and the second largest gold depository in the world. Today the Carlin Trend reportedly hosts more than 120 million ounces of known proven and probable reserves and has produced more than 60 million ounces of gold in past production and Nevada is the largest gold producing area in the world per square kilometer.
At the height of the Nevada gold rush, in 1974, Andy Wallace joined Cordex, becoming a full time geologist in 1978 and eventually Manager of Exploration in 1985. Cordex is credited with an unprecedented nine gold discoveries in Nevada, a number of which were under Mr. Wallace's management, including the 5 million ounce Marigold mine now operated by Goldcorp and the 12 million ounce Stonehouse/Lone Tree mines and the Daisy mine now controlled by Newmont.
