It supplies 17MW to Dacian Gold's Mount Morgan gold project on an eight year contract with the option for Dacian to extend for a further three years.

The deal was executed in February and includes an initial 10-year term with the option for Newmont to extend for another decade.
The company continues to work on projects like the hybrid diesel/ solar plant at the Nova copper-nickel operation in the Fraser Range.
