30 Second Briefing
GR Engineering Services has secured an EPC contract from Venturex Sulphur Springs Pty Ltd, a Develop Global subsidiary, to design and construct a 1.5 Mt/y copper-silver-zinc processing plant for the Yitirrti (formerly Sulphur Springs) project in Western Australia. The scope covers full engineering, procurement and construction of the concentrator and associated infrastructure, positioning the project for medium-scale sulphide ore throughput. Plant design choices and materials handling layouts will be critical for managing polymetallic recovery and abrasive sulphide ore wear in a remote Pilbara-style environment.

Our Take
A 1.5 Mt/y plant in Western Australia puts Yitirrti in the mid-tier base metals bracket in our database, large enough to justify modern flotation and dewatering circuits but still small enough that modular or staged construction by GR Engineering Services is viable.
Copper-silver-zinc combinations like Yitirrti feature in many of the 345 copper/silver keyword-matched pieces, and operators often rely on silver and zinc credits to keep all-in sustaining costs competitive against single-commodity copper mines.
GR Engineering Services appears frequently in our Projects and Contract Award coverage for similar-scale Australian plants, suggesting Develop Global is prioritising a contractor with a track record of delivering concentrators under local regulatory and labour-market conditions.
