Director Dr. Paul L. Zweng has blended a technical and financial background in exploration and mining over the past 25 years. Most recently Dr. Zweng was the COO and later President/CEO of QGX Ltd, a TSX-listed company with mineral projects in Mongolia. During this period, QGX developed the Baruun Naran coking-thermal coal project, southern Mongolia, into a 253 Mt measured and indicated resource with a positive pre-feasibility study (after-tax NPV (10% discount rate) of US$499 million). QGX at this time also made an important discovery at Golden Hills, the fourth largest copper deposit ever discovered in Mongolia after Oyu Tolgoi, Erdenet, and Tsagaan Suvarga. In September 2008 QGX was acquired by the Kerry Group (Hong Kong) for C$270 million, delivering substantial returns to shareholders.
Dr. Zweng was a Research Analyst and later Partner at Palo Alto Investors, a hedge fund based in California from 1999 until end 2003. While at Palo Alto Investors, Dr. Zweng conducted due diligence and lead investment decisions on mining and exploration as well as technology companies. He was featured twice in Barron’s “Plugged In” column (31 Aug 1999; 6 Sept 1999).
Dr. Zweng also was the winner of the last Wall Street Journal “Heard in California” stock-picking contest (Jan-Jun 2000: 17.4%) before the contest was discontinued. Dr. Zweng led BHP Copper’s new business development efforts in the Copperbelt of Africa from 1997 until 1999. He formulated BHP Copper’s African strategy, conducted financial and technical evaluations of African copper projects, developed business relationships with DR Congo and Zambian government officials, and recommended asset acquisitions to senior management. These efforts led to BHP securing the Tenke Fungurume project, one of the world’s richest and largest copper-cobalt deposits.
From 1995 until 1997, Dr. Zweng was the Manager of Exploration & Geology of BHP’s Cu-Au-Ag mine, Tintaya, Peru. He helped to grow Tintaya into one of the world’s largest copper skarn districts by discovering over 150 million tonnes of high-grade ore, including enough copper oxide ore to build an SX-EW facility. He managed the mine geology and annual budgets of >$10 million with workforce of over 80 employees and contractors.
Dr. Zweng was the founder, CEO and Chairman of Patagonia Exploration, a California-based exploration company focused on mineral exploration in southernmost Chile and Argentina. During 1988-1995, Dr. Zweng discovered two mineral prospects, with one optioned to Echo Bay Mines.
He received two B.Sc. degrees with distinction in Geology and Applied Earth Sciences (Mineral Economics) from Stanford University (California) in 1980, a M.Sc. degree in Geology from Queen’s University (Ontario) in 1984 and a Ph.D. in Applied Earth Sciences (Ore Deposits) from Stanford University (California) in 1993. Dr. Zweng has published several articles and abstracts on geology and ore deposits in two languages in scientific journals.
