Highlights
- Dugald River Zinc Mine is shifting towards renewable energy, significantly reducing carbon emissions.
- Solar energy now supplies a third of the mine's power needs, with wind energy being the next step.
- A feasibility study for wind energy is underway, aiming to meet 75% of energy requirements through renewables.
The Dugald River Zinc Mine, located in northwest Queensland, has taken a pioneering step towards sustainability by transitioning to renewable energy sources. Owned by the mid-tier miner MMG Ltd (ASX:MMG), the mine has historically relied on the gas-powered Diamantina Power Station to meet its energy needs. However, the mine is now embracing a green energy shift, becoming a key customer of the Dugald River Solar Farm near Mount Isa. This solar farm, which became operational in March of the previous year, currently supplies approximately one-third of the mine’s energy requirements, contributing to a significant 33% reduction in carbon emissions.
Tim Akroyd, the general manager of the Dugald River Mine, highlighted the importance of this shift to renewables, describing the transition as a major cost-saving initiative. He further revealed that the mine is exploring the potential of wind energy as an additional renewable source. The region is known for its strong night winds, making wind power an ideal complement to solar energy, which would provide the mine with continuous, round-the-clock renewable energy.
A feasibility study is currently in progress to assess the viability of wind energy for the mine. Early measurements using radar technology have shown promising results, indicating that wind could work in synergy with solar energy to meet the mine's energy needs at all hours. However, despite these positive prospects, the mine still depends on gas-fired backup power due to the current lack of battery storage solutions.
The mine's goal is to meet 75% of its energy demands through renewable sources, in line with the broader energy transformation in the region. This effort is supported by the CopperString 2032 project, an ambitious initiative that aims to connect northwest Queensland to the national electricity grid. The project is expected to attract significant investment in renewable energy, further bolstering the region's sustainable mining efforts.
University of Southern Queensland’s associate professor, Andreas Helwig, praised the Dugald River Mine's efforts, recognizing the positive impact this shift could have on other mining operations. He also emphasized the importance of addressing the environmental concerns related to renewable infrastructure, especially at the end of its lifecycle.
The feasibility study is expected to conclude mid-year, with construction of the wind energy project slated to begin by the end of the year. As the mining industry looks toward more sustainable practices, the Dugald River Zinc Mine’s journey offers a promising model for others to follow.
