NEI MONGOL REGION, China Thanks to an ATLAS COPCO CS-1000P6L diamond drill, the 217 gold project near the Mongolian border is a step closer to development. The project is a large, medium-grade deposit operated by PACIFIC MINERALS of Toronto.
The deposit was discovered by a team from the Bureau of Geology and Mineral Resources of Inner Mongolia during a regional stream sediment sampling program in the 1980s. The property was actively explored from 1992 through 1998. Exploration in 1999 included satellite imagery, mapping, trenching, rock sampling, and 2,800 metres of diamond drilling. In 2002 Pacific Minerals acquired an option on the 217 property from IVANHOE MINES.
Core drilling with the CS-1000 began in July 2003 to delineate the deposit and update the resource model. The drill is operating at a depth of more than 600 metres in broken sedimentary rock. With Tuff core barrels and Hobic bits, the drill has been averaging 45 to 50 metres per 10-hour shift, reports Atlas Copco.
The trailer-mounted CS-1000 has proven such a dependable workhorse that the drilling contractor has ordered two more rigs, another P6L (long stroke) and a P6, both of which should arrive in China by the end of March. Specifications for the CS-1000 and other Atlas Copco drills are available at www.atlascopco.com.
