After merging with Nustar Mining Corporation in 2006, Intrepid’s Paulsen Mine produced 70,000 to 78,000 ounces of gold per year for four years, before it was sold to Northern Star Resources in 2010. Later, as Director, Dr. Curtis saw Intrepid transition through merger and acquisition to become a gold producer and developer and, as Intrepid Mines Ltd., ultimately attain a market capitalization in excess of $1.2 billion, due to the discovery of the Tujuh Bukit copper-gold-silver deposit, one of Indonesia’s largest discoveries containing more than 25 M ounces of gold, 80 M ounces of silver and more than 10 billion pounds of copper.
