Congratulations Sandfire management for doing this from a renewable energy pov.

Website:

"The project comprises a 10.6MW solar array utilising 34,080 solar panels over 20 hectares. It uses single-axis tracking technology, combined with 6MW of short term battery storage and will be located near the site of the current DeGrussa underground mine and 1.5Mtpa Concentrator.
The solar power station will be fully integrated with the existing 19MW diesel-fired power station at DeGrussa. This integrated system will be designed with the diesel power station continuing to provide base-load power to the DeGrussa mine with sufficient minimum load to ensure it can respond quickly to meet the power requirements of the process plant and underground mine.
The project is expected to achieve savings in the consumption of diesel fuel and will deliver a significant environmental benefit for DeGrussa, reducing its CO₂ emissions by an estimated 12,000 tonnes per year."

It has economic benefits too.

From the website, again:

"We identified some time ago that solar power presented an exciting opportunity for us to participate in a low-risk renewable energy initiative at DeGrussa…the DeGrussa Solar Power Project has the potential to reduce the mine’s diesel consumption and is consistent with our relentless focus on driving down costs.” – Sandfire Managing Director, Karl Simich"

It took the company just 3 years to go from discovery to mine. It keeps on exploring and discovering and it innovates (with solar power). It's an impressive CV.
