The BHP Billiton Mitsubishi Alliance (BMA) is offering more meetings with the Single Bargaining Unit (SBU) in an attempt to end the long running industrial dispute.
A BMA spokesperson told the SBU, which is made up of a number of workers unions, that it is aiming for more meetings "in order to further accelerate" enterprise agreement negotiations, according to the CQ News.
"Employees are providing the company with ongoing feedback that they are frustrated with the speed of negotiations and want more meetings so that an agreement can be finalised as soon as possible," they said.
"BMA again calls on the unions to withdraw all industrial action when productive negotiations continue, particularly while they are unwilling to commit to additional meetings.
"The ongoing industrial action causes unnecessary financial harm to the business and our employees, particularly in the lead-up to Christmas and will not assist in finalising negotiations more quickly."
It comes after more than 90% of unionised miners rejected a BMA offer which consisted of a 5 % year-on-year pay rise for three years, a $15,000 bonus and other benefits.
The unions said at the time that they were still opposed to the deal, and are in part looking for an arrangement with less working hours.
Following the rejection, the SBU announced further industrial action.
It has also filed notices for industrial action this week, depending on whether BMA accepts its latest proposals.
