NRW Holdings (ASX:NWH) said its Primero Group unit secured a contract for Ramelius Resources' (ASX:RMS) Mount Magnet expansion project in Western Australia, according to a Monday filing with the Australian bourse.

The scope of work includes the construction of a crushing circuit and coarse ore stockpile, installation of a new grinding circuit, leach tanks and associated gold-processing infrastructure, resulting in an additional 3 million tonnes per annum of processing capacity, per the filing.

In May, the company's NRW Contracting unit obtained a contract worth about AU$200 million for the Tonkin Highway Grade Separations, Hale Road, and Welshpool Road East project by Main Roads Western Australia. Optional works associated with that project have now been awarded, increasing the total contract value to about AU$300 million.

Together, the Ramelius contract and Main Roads Western Australia optional works award have a total value of around AU$313 million, NRW Holdings said.

NRW Holdings' shares were down 1% in recent Monday trade.
