Westgold signs gas and renewables agreements with Pacific Energy, CEFA

Westgold Resources, in line with its ongoing objectives to enhance profitability and focus on cost optimisation, has executed a new Electricity Purchase Agreement with independent power provider Pacific Energy and a new LNG Supply Agreement with Clean Energy Fuels Australia (CEFA).

These agreements will deliver substantial operating cost savings to Westgold in its 2023-2024 financial years onwards of around A$100/oz ($68/oz) at the current diesel price and supports its commitment to environmental, social and governance (ESG) initiatives that will reduce the company’s long term greenhouse gas emissions, it said.

Under the build-own-operate agreement with Pacific Energy, Westgold will materially reduce diesel consumption by replacing six diesel-fired power stations (two owned and operated by Pacific Energy) with four new, highly efficient gas-fired power stations to incorporate renewable energy options and use solar power and battery storage across the Bryah and Murchison Operations. Critically for Westgold, this transition to a mixed generation platform includes renewables and gas and is expected to reduce carbon emissions from diesel-powered generators by over 57%, due to the higher integration of renewables (34% solar) and cleaner fuel (gas versus diesel), the company said.

Westgold’s first new Pacific Energy power station will be commissioned in July 2023 at the Tuckabianna processing hub, with the three additional new power plants scheduled for commissioning from September 2023.

Westgold has concurrently signed a bulk LNG supply agreement with CEFA. CEFA will supply Westgold from its expanded LNG plant located at Mt Magnet (pictured), 80 km south of Cue. This plant is currently providing LNG to another Pacific Energy power plant in the Murchison region and provides a substantial advantage due to its proximity to Westgold’s operations. CEFA will fund and construct satellite LNG facilities (primarily comprising LNG storage and re-gasification equipment) at Westgold’s project sites, with the LNG trucked direct from its plant at Mt Magnet.

The new gas and solar power station to be commissioned at Westgold’s Meekatharra operations will also serve to simplify power generation by removing smaller diesel fired power stations at the Paddy’s Flat and Bluebird underground mines and providing them power from a larger gas-fired power station via overhead powerlines, according to the company.

Westgold Managing Director, Wayne Bramwell, said: “The transition to a cleaner, more efficient energy platform that utilises renewables and gas in financial year 2023 is strategic for Westgold. It is an important step in meeting our ESG targets but is pivotal to reducing the operating cost of our business.

“Westgold has selected two industry leaders in Pacific Energy and CEFA to work with us in this transition and we look forward to seeing the benefits that integrating renewable power and cleaner energy alternatives can deliver to our business and the communities within which we work.”

Normet to provide rock reinforcement ground support at Westgold ops

Normet says it has agreed a new partnership with Westgold Resources Ltd for the supply of rock reinforcement ground support to all its operations in Australia.

Normet’s Australian Business Development Manager, Jamie Rewell, said: “Westgold is an established Australian producer with major mining centres in the Murchison, and the partnership is a testament of Normet’s commitment to supporting Westgold’s growth in the region.

“With Normet’s global experience and expertise, we are well positioned to partner with Westgold for continuous improvement on safety and productivity of their operations. Normet would like to thank Westgold for trusting us with their business and look forward to be a part of their continued success.”

Westgold has a 7.9 Moz resource base with multiple mines, including six underground operations, and three processing hubs with a circa-4 Mt/y milling capacity in the Murchison and Bryah Basin regions.

Dyno Nobel’s CyberDet I underground wireless blasting tech hits the mark at Westgold’s Big Bell

Dyno Nobel says it has completed the first ever underground wireless detonator blast in Western Australia, using its ground-breaking wireless technology, CyberDet I®.

The blast, on June 1, 2021 at Westgold’s Big Bell underground gold mine, saw 34 CyberDet I detonators fired, producing “outstanding results”, including a well fragmented muckpile, the Incitec Pivot Ltd business reported.

Big Bell is a premier asset in Westgold’s Cue portfolio of mines (expected to produce 100,000-110,000 oz/y for Westgold over the long-term, underwritten by output from the Big Bell mine, Westgold says) and the blast was undertaken following approval from the Department of Mines, Industry Regulation and Safety.

Dyno Nobel Asia Pacific President, Greg Hayne, said the blast in Western Australia’s mid-west region was a significant milestone for Dyno Nobel’s wireless detonator offering.

“We are so pleased to be able to partner with Westgold on the first underground wireless blast ever in WA,” Hayne said. “The blast was a great success and it’s been really pleasing to hear Westgold’s feedback that it believes CyberDet I will deliver improved safety and efficiency.”

CyberDet I is designed to allow operators to work in a safer environment during the blast loading process. The technology also facilitates a shorter blast cycle, providing the potential to increase the number of tonnes mined.

“CyberDet I is Dyno Nobel’s through-the-earth wireless detonator offering, developed on the back of customers telling us it’s technology they need,” Hayne said.

Incitec Pivot Ltd Chief Technology Officer, Robert Rounsley, said CyberDet I highlighted the group’s commitment to advanced technology development.

“One of the key advantages of our wireless offering is its portable design,” he said. “The flexible nature of our communications antenna provides significant operational advantages for our users.”

The next step for CyberDet I will be further trials in Australia, with several customers already interested in the wireless technology, according to the company.

“We’re looking forward to showing more of our customers the benefits of CyberDet I.” Hayne said. “It is just one of our premium technology offerings focused on meeting the needs of our customers. We are proud of our customer partnerships which are creating innovative, practical improvements in safety, productivity and environmental performance.”
