Southern Cross Electrical Engineering (SCEE) has additional contracts for electrical and instrumentation works across Sino Iron's minerals processing facilities.
Earlier this month Sino awarded SCEE a $10 million contract for electrical and instrumentation installation, testing, and commissioning work at the mine's grinding mills at concentrate processing lines 3,4,5 and 6.
Now it has awarded the contractor more than $70 million worth of additional E&I works at the site.
This work has been awarded in two packages, with the total scope covering installation and commissioning of all electrical and instrumentation works across process lines 3 to 6.
The work is scheduled to start next month.
Commenting on the win, SCEE managing director Simon Haigh said he is "extremely pleased that we have been able to secure this additional work, having identified Sino Iron as a core project for SCEE over the next two years".
"The addition of approximately $80 million of new work provides a timely boost to our order book as we move in to FY 2015."
