The drilling will test targets at each of the Cathedrals Prospect, the Stricklands Prospect and the Investigators Prospect.
The program will cover 19 holes to test new electromagnetic targets and interpreted extensions to known high-grade nickel-copper-PGE mineralisation.
John Prineas, executive chairman, commented:
"Following on from the tremendous success of our 2016 drilling at Mt Alexander, we have conducted a comprehensive review of results and completed detailed preparation for our 2017 drill program.
"We are confident that the 2017 drilling will discover more high grade nickel-copper sulphides in the Cathedrals Belt and continue our progress towards establishing a resource base at the project."
St George will have extensive news flow over coming months.
The program has the potential to discover additional massive nickel-copper sulphides.
