Macmahon Holdings extends stay at PT Agincourt’s Martabe mine

Macmahon Holdings says it has extended its appointment by PT Agincourt Resources (PTAR) as the mining contractor for the Martabe gold project in North Sumatra, Indonesia.

Macmahon has been working to support PTAR at the Martabe mine site since 2016 and, in that time, its workforce on site has grown to over 600. The scope for Macmahon on the next stage of development will involve open-cut mining activities including drilling, loading, hauling and mine site development.

The contract extension commences on April 1, 2023, for a seven-year period with the option to extend for a further two years. It is expected to generate revenue of A$350 million ($234 million) in the first seven years, adding to Macmahon’s secured order book.

Macmahon will continue to integrate safety, environmental and social considerations into its operations at Martabe and looks forward to continuing this work in partnership with PTAR and
the local communities on all these areas, it said.

The contract value of the successful extension at Martabe and other recent contract awards in financial year 2023 total approximately A$2.5 billion, which exceeds Macmahon’s financial year 2023 order book run-off. As a result, the company is better positioned to strategically pursue low-capital intensity opportunities.

Macmahon CEO and Managing Director, Michael Finnegan, said: “We are delighted to be re-appointed by PTAR as the mining contractor for its Martabe gold project and believe this reflects the significant efficiencies delivered on the project. Since 2016 we have built, and continue to build, a strong relationship with the PTAR team and look forward to being part of the further successful development of the mine. I would like to thank our Macmahon team at the Martabe project in Indonesia. Their continued dedication and support are what makes this project successful.”

GreenGold’s ReCYN to detoxify tailings, recover cyanide and copper at Martabe

Technology provider GreenGold says it has been awarded a ReCYN™ design and install contract with PT Agincourt Resources to detoxify tailings and recover cyanide and copper at its Martabe gold-silver operation in Sumatra, Indonesia.

Jakarta- and Perth-based GreenGold will deliver the project with preferred fabricators for specialist equipment packages, the company said.

In a report published last year, Whittle Consulting called the ReCYN process “a world-leading approach” in cyanide recovery, metal recovery and tailings detoxification. “Based on an innovative resin-bead absorbent, ReCYN reduces cyanide consumption by 50%, capturing free cyanide from the plant tailings and recycling it back into the leach circuit while recovering metal complexes and making them available for sale,” Whittle said.

Whittle also said adopting the technology could provide a $126.9 million upside to the project.

GreenGold said it had received the contract following a record influx of enquires for the technology.

GreenGold CEO, Malcolm Paterson, said of the Martabe contract: “We have come up with an elegant design to fit the space constrained site. We also will be recovering cyanide and copper which previously was destroyed or sent to tails, turning a cost into an economic benefit for the mine.

“We are looking forward to delivering on this strategically important project, and continuing to build on our proven metallurgy and process capability within the precious/base metals sector globally.”

The Martabe mine has a resource base of some 7.4 Moz of gold and 69 Moz of silver.
