Australian miner Southern Gold Ltd will commence its next phase of drilling for gold samples in its northeastern Cambodian mineral concessions within two weeks, the company said Monday in a statement. The work marks the beginning of its planned 2009-2010 exploration programme, which will see further investigation of previously identified deposits of the precious metal as well as surveys of its unexplored properties. Monday saw the company’s share price rise 13.8 percent on the Australian Securities Exchange to close at US$0.152 as gold bullion prices rose on regional markets.
