The company planned to use a boring machine to dig an exploratory tunnel and conduct a pre-feasibility study at the site but this work has been put on hold after potential contractors quoted higher than expected rates, reports Bloomberg.
The firm’s chief executive officer Terry Burgess told Bloomberg that exploring the South Australia mine at this point in time would be expensive.
"I think we are realising that this was costing us extra money by asking the contractors to do things more quickly," Burgess added.
"If the market continues to slow down with regards to mining services, we might see lower costs."
Burgess added that the company plans to take a decision on the Carrapateena mine in 2015 as the number of resource projects would likely be reduced, which would make hiring a contractor for mining services cheaper.
The company will renegotiate its contracts with suppliers, which were agreed when mining investment was at its peak in Australia.
