GR Engineering Services Limited has been awarded a design and construct contract with Develop Global Limited for the Woodlawn Restart project, in New South Wales, Australia.

Woodlawn is primarily a copper-zinc mine located in the Lachlan Ford belt in NSW, 250 km southwest of Sydney and 40 km south of Goulburn.

The contract value is A$25.7 million ($17.5 million) and the scope of work includes the refurbishment flowsheet and operability improvements of the existing process plant and associated infrastructure. The project is expected to be completed in the second half of thr 2025 financial year.

Tony Patrizi, Managing Director, said: “We are pleased to have been engaged by Develop to play an important role on the Woodlawn Restart project. We
look forward to continuing to work collaboratively with Develop to deliver a safe and successful outcome for this project and to assist them with their future growth plans.”

Woodlawn has a resource of 11.3 Mt at 1.8% Cu, 5.8% Zn, 2.1% Pb, 46 g/t Ag and 0.5 g/t Au, for contained metal of 190,000 t of copper and 650,000 t of zinc.

The mine plan estimates that Woodlawn will produce an average of 12,000 t/y of copper and 36,000 t/y of zinc metal in payable streams over an estimated 10-year mine life.

GR Engineering Services says it has executed engineering, procurement and construction (EPC) contracts with K92 Mining Ltd, a subsidiary of TSX-listed K92 Mining Inc, for a 1.2 Mtpa process plant at the Kainantu gold mine in Papua New Guinea.

As announced on July 25, 2023, GR Engineering had previously received a Letter of Intent from K92 Mining Ltd. The contract’s sum is $81 million. Site mobilisation is expected to occur in January 2024.

Tony Patrizi, Managing Director of GR Engineering, said: “GR Engineering has a long track record of successful project delivery in the mineral processing sector. We see this contract award as a strong endorsement by K92 Mining Inc of GR Engineering’s proven process design record and EPC delivery capability.”

K92 Mining owns and operates Kainantu, a producing gold mine that has existing infrastructure at site. The EPC works are being performed as part of K92 Mining’s Stage 3 Expansion plans. It has successfully executed multiple expansions at the Kainantu gold mine, after restarting operations at the site in 2016.

Evolution Mining has awarded a contract to GR Engineering Services Limited to complete the plant expansion works at its Mungari gold mine in Western Australia.

These works, part of an engineering, procurement and construction contract, are expected to total A$155 million ($100 million) and are within the project budget and schedule as part of the company’s previously announced commitment to invest A$250 million to increase the site’s processing capacity from 2 Mt/y to 4.2 Mt/y, Evolution says. It also includes required changes to process plant buildings and associated infrastructure, according to GR Engineering.

Initial engineering design and procurement works have commenced with site works commencing in mid-January 2024. The project has an estimated 30-month construction period including long-lead items and approvals, with commissioning expected by the end of the March 2026 quarter.

Targeting gold production of 200,000 oz/y for the life of the mine, this project is expected to reduce Mungari’s All-In Sustaining Cost by 18% to $1,750/oz and extend the mine life to 2038, Evolution says.

Evolution Mining’s Managing Director and Chief Executive Officer, Lawrie Conway, said: “The award of this contract is a major milestone for the Mungari Future Growth project. It secures the critical processing plant infrastructure within our budgeted costs, locking in over 60% of the project costs, and secures a delivery time within the approved project schedule.

“The feasibility study established a sound investment case with an internal rate of return for the project of between 19% and 28%, at a conservative A$2,400/oz and spot price of A$2,965/oz, respectively.”

Tony Patrizi, Managing Director of GR Engineering, said: “We are extremely pleased that Evolution Mining, one the world’s leading tier one gold producers, has selected GR Engineering to deliver the Future Growth project at Mungari. GR Engineering has a long track record of successful project delivery in the mineral processing sector. We see this contract award as a strong endorsement of GR Engineering’s proven process design record and EPC delivery capability.”

GR Engineering Services says it has entered into two contracts with OZ Minerals Musgrave Operations Pty Ltd, a wholly owned subsidiary of OZ Minerals Limited, for the design and construction works of the West Musgrave mineral processing plant in Western Australia.

GR Engineering has been engaged by the company to provide the following services for the West Musgrave project:

  • Engineering design, drafting, project management and commissioning; and
  • Structural, mechanical, piping, electrical and instrumentation construction works.

GR Engineering’s wholly owned subsidiary, Mipac Pty Ltd, will also be engaged within the GR Engineering scope of work to provide specialist electrical and instrumentation services.

The estimated revenue from the delivery of these contracts will be A$312 million ($211 million) over a two year period.

Tony Patrizi, Managing Director of GR Engineering, said: “We are pleased to have been engaged by OZ Minerals to play a key role in the delivery of the world- class West Musgrave project. This is an important project for GR Engineering as we have worked with OZ Minerals over many years on projects within the OZ Minerals group, including the West Musgrave project, and see this award as a strong endorsement of our proven delivery capabilities.”

Debbie Morrow, Projects Executive for OZ Minerals, added: “We’re delighted to be working with GR Engineering on the design and construction of the minerals processing plant for the West Musgrave project, which is set to be one of the largest, lowest cost, lowest emissions copper-nickel projects.”

The West Musgrave project feasibility study the OZ Minerals Board signed off last year details a 13.5 Mt/y operation with average production of circa-28,000 t/y of nickel and circa-35,000 t/y of copper over a 24-year operating life.

GR Engineering Services has been appointed preferred tenderer by Boab Metals Limited in relation to the engineering, procurement and construction (EPC) contract for the processing plant and non-process infrastructure for the Sorby Hills lead-silver project in Kununurra, Western Australia.

GR Engineering and Sorby Hills Management Pty Ltd (the manager of the Sorby Hills joint venture) will execute an agreement shortly to commence detailed design and selected ordering of long lead items, prior to the award of an EPC contract, it said. The EPC contract will be subject to the achievement of final investment decision.

Boab said the scope of work includes a process plant with a capacity of 2.25 Mt/y, representing a 50% increase over that considered in the Sorby Hills prefeasibility study. This 2020 study envisaged a 1.5 Mt/y throughput rate over an initial 10-year mine life, with the PFS combining ore drawn from three open pits with a processing plant employing conventional milling and flotation with a beneficiation plant between the coarse crush (dry end) and the grind and flotation circuit (wet end).

The PFS indicated steady state annual production of concentrate containing approximately 50,000 t/y of lead and 1.5 Moz/y of silver.

The tendered price for GR Engineering’s EPC agreement is commensurate with the proposed capacity expansion and will form the basis of capital cost estimates for the definitive feasibility study, Boab said.

GR Engineering’s Acting Managing Director, Tony Patrizi, said: “GR Engineering is pleased to have been selected by Boab as the preferred tenderer for the delivery of the project. GR Engineering has a strong track record of successful project delivery in the base metals space. Aligned with GR Engineering’s core values, it is exciting to work on this important regional project that has already implemented tangible green initiatives. We look forward to working with the Boab team.”

Boab owns 75% of the Sorby Hills joint venture project, with the remainder owned by Henan Yuguang Gold Lead Co. Ltd.
