Companies are increasingly looking to Western Australia to locate high-grade silica mines to meet global demand. However, there could be an environmental cost.
The key points
- Global demand for solar power is increasing.
- WA is a popular destination for high-grade silica.
- South West communities fear that mining will decimate state forests and natural resource.
Silica is a key ingredient in solar panels. Dr Tejas Bhatelia, a senior research academic at Curtin University and chemical engineer, stated that some forecasts suggested that up to 25% of the world’s energy needs could be met by renewable energy.
“If you took some sand to your backyard, it’s silicon. It’s everywhere.”
“[But]There is a global imbalance in where high-quality, metallurgical Silica is found in nature.
“At one point, we’re going to see an inequality, we’re going to see the point where we won’t be producing enough metallurgical quality silicone to meet the energy demands that we have.”
Mining has environmental and health risks
Allup Silica, a junior exploration company based in Perth, has recently listed its four WA-based exploration companies on the ASX. The company is looking to raise $5 million to finance their high-purity silica-sands projects.
Locals are worried about the possible impact of Allup Silica’s mining and exploration licences being granted to one of their tenements in the South West.
Quinninup Community Association members expressed concern that if Allup Silica’s Antwalker Project is allowed for mining, it could lead to native bushland being cleared as well as a significant water source being taken from or polluted by the mining process.
Alice Beach, Quinninup resident, is a registered nurse who expressed concern about the environmental effects and health risks of silicosis.
“With the global trends [moving]We are not moving towards net zero and reducing carbon emission if we look at cutting down and mining the forests in the south.
Andrew Haythorpe is the chairman of Allup Silica. He stated that the company aims to work with communities and build community relationships as partof the lengthy processes before mining can start.
“If there is a mining proposal at that stage, it would address the risk of silica dust as well as any health effects resulting from silica dust.
“The Quinninup area is still in an early application stage. Given its location, should exploration be allowed, it will be subjected to extensive and rigorous community and environmental regulation, consultation, and oversight.”
