Identifying companies with the highest stranded asset risk is a complex process that requires a detailed analysis of each company’s specific situation. It involves assessing factors such as the type of minerals mined, the location of the mine, the company’s level of debt, and the extent to which it is exposed to technological, regulatory, and market risks.

That being said, there are several factors that could increase the stranded asset risk for mining companies operating in Australia. Some of these factors include:

1. Coal mining: As the world moves towards renewable energy, the demand for coal is expected to decline. This could result in coal mines becoming uneconomic and stranded assets. Therefore, companies with significant coal mining operations, such as BHP Group, Rio Tinto, and Anglo American, could be at risk.
2. Iron ore mining: Iron ore is Australia’s biggest export, but there is a risk that demand for it could decline if steel production becomes more sustainable. This could result in iron ore mines becoming stranded assets. Therefore, companies with significant iron ore mining operations, such as BHP Group, Rio Tinto, and Fortescue Metals Group, could be at risk.
3. Regulatory changes: Regulatory changes that limit the amount of carbon emissions or water use from mining operations could increase the stranded asset risk for mining companies. Companies that operate in regions that are prone to drought or face stringent environmental regulations, such as New South Wales and Western Australia, could be at higher risk.
