RVP was a natural resources fund making investments primarily in early-stage exploration/development companies with projects located around the world. During a portion of this time from May 7, 2010 to January 9, 2012, Dr. Zweng became CEO of Bellhaven Copper & Gold, one of RVP’s equity holdings.

Dr. Zweng co-founded Antares Minerals, a TSX-V listed company with projects in Argentina and Peru in late 2003 through the acquisition of a shell company, Planet Ventures. Dr. Zweng hired the initial management team and acquired its first mineral projects, including the Rio Grande copper-gold project located in Argentina. In March, 2005, Antares acquired from Phelps Dodge the Haquira copper oxide project in Peru and later discovered copper-molybdenum-gold sulfide mineralization below the oxide at Haquira East in February, 2007. The announcement in early January 2008 of drill-hole AHAD-107, containing 943 m @ 0.65% copper, confirmed that a major discovery had been made at Haquira. First Quantum (TSX-FM) acquired Antares for C$650 million in December 2010.
Dr. Zweng was the COO and then President/CEO of QGX Ltd, a TSX-listed company with mineral projects in Mongolia. When he joined QGX in early 2003, its market capitalization was C$30 million. During his tenure, QGX developed the Baruun Naran coking-thermal coal project into a 253 Mt resource with a positive pre-feasibility study (after-tax NPV@10% of US$499 million). QGX at this time also discovered Golden Hills, the fourth largest copper deposit ever discovered in Mongolia after Oyu Tolgoi, Erdenet, and Tsagaan Suvarga. Kerry Group (Hong Kong) acquired QGX for C$265 million in September 2008—the same month that Lehman Brothers failed.

From 1995 until 1997, Dr. Zweng was the Manager of Exploration & Geology of BHP’s copper-(gold-silver) 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 support the building of an SX-EW operation (158 Mt @ 1.20% Cu). He led BHP’s exploration efforts in the discoveries of the Coroccohuayco (92 Mt @ 3.10% Cu) and Antapaccay (520 Mt @ 0.72% Cu) deposits.
