A joint venture (JV) over the Marillana iron-ore project, in the Pilbara, between ASX-listed Mineral Resources (MRL) and Brockman Mining has kicked off, after the parties executed a mine-to-ship logistics agreement for the transport of the Marillana ore to Port Hedland. MRL said on Tuesday that the Marillana ore will be transported through a light rail system from the mine to the port.
