The Abra base metals project in Western Australia is racing forward to first production in 2023 after the project owners signed off a positive final investment decision (FID) for the mine’s development.

The FID was made following the satisfaction of key conditions to draw in excess of $30 million under a debt facility.

As of May 31, 2021, the project is 17% complete, with completed works including: construction and commissioning of a 280-unit mine site village; mining of the box cut (pictured); box cut ground support works; installation of site communications; and various site clearing, roadworks and civil works.

“As a result, Abra is largely prepared for the deployment of key contractors for the construction of the plant and auxiliary infrastructure, and deployment of the underground mining contractor,” Galena Mining, the 77.28% owner of the project, said.

Among the key contractors at Abra is GR Engineering Services, which is set to deliver a 1.2 Mt/y lead sulphide flotation process plant and ancillary infrastructure under a A$75 million ($58 million) guaranteed maximum price arrangement. The underground mining services contract has been awarded to a tier one Australian mining contractor, Galena said without naming the contract recipient.

“Under the current project schedule, procurement of certain long-lead items will take place immediately,” Galena said. “The underground mining contractor is expected to initiate the portal and decline development in the third (September) quarter of 2021 calendar year and physical on-site plant construction is expected to commence in the fourth (December) quarter of 2021 calendar year.”

Related to the decision to move ahead with development, Galena said it was appointing Anthony James as Managing Director of the company, a mining engineer with senior underground operational and development experience. He will replace current MD Alex Molyneaux who will remain a director of the company.

This definitive feasibility study outlined development of a mine and processing facility with a 16-year life producing a high-value, high-grade lead-silver concentrate containing around 95,000 t/y of lead and 805,000 oz/y of silver after ramp-up.

Abra Mining Pty Ltd, the joint venture company behind the Abra base metals project, has executed a power purchase agreement (PPA) with Contract Power Australia that could see the construction and operation of a hybrid power generation facility made up of a natural gas and solar energy array at the Western Australia project.

Announcing the PPA, Galena Mining, which owns 77.28% of the project, said Contract Power will build, own and operate an integrated hybrid power generation facility combining a 10 MW natural gas fired power station, a 6 MW solar array, 2 MW of battery energy storage and a 900 Kl LNG storage and regasification facility.

Power will be purchased by Abra under the PPA for an initial term of 16-years (extendable), it said.

Galena Managing Director, Alex Molyneux, said: “We’re pleased to partner with Contract Power on a clean, cost-effective power solution for Abra. Integrating solar with relatively clean natural gas instead of diesel achieves a marked reduction in Abra’s carbon footprint compared to alternatives considered in the tender process.

“Pleasingly, the design also offered the most cost-effective solution, in line with our feasibility study estimates.”

A Western Australia-based company wholly-owned by Pacific Energy Ltd, Contract Power specialises in the design, construction and operation of remote power stations for the mining and government sectors.

Contract Power has operated power stations around Australia under turnkey build-own-operate arrangements since 1999, and recent projects include a 56 MW gas fired power station for Mineral Resources Ltd’s Wodgina lithium project, a 18 MW gas fired station for Capricorn Resources’ Karlawinda project and a 18 MW gas and diesel power station at Wiluna Mining Corp‘s Wiluna gold project.

Contract Power’s Managing Director, Leon Hodges, said: “We are very pleased to be working with Galena on this important project and look forward to rewarding their confidence by delivering a world-class hybrid power station.

“Contract Power’s combined LNG and renewables integration capability has allowed our design team to maximise solar penetration as high as the economics and technology allows, providing the Abra project with the highest reliability and lowest cost of power on an unsubsidised basis.”

The PPA remains subject to the condition of Abra Mining Pty Ltd proceeding to final investment decision for the project, Galena said.
