Rio Tinto Copper Expansion Sets Stage for Long-Term Growth
Rio Tinto's shares are often associated with cyclical mining operations, which can be volatile and challenging for investors to navigate. However, a closer look at the company's long-term strategy reveals a different story.
At approximately $180.44 per share, Rio Tinto trades at around 15 times forecast earnings in both FY26 and FY27, based on consensus EPS estimates of roughly $12.07 and $12.04 respectively. While this may seem uninspiring for growth investors, the company's diversified asset base and focus on long-duration income and commodity growth make it an attractive opportunity for those willing to hold onto their shares through market fluctuations.
Rio Tinto is not a compounder in the traditional sense, but rather a company that operates on a different logic. Its earnings do not compound in a straight line, but instead oscillate with iron ore prices, copper demand, and macroeconomic cycles, particularly in China. A buy-and-hold approach requires patience and the willingness to look through earnings volatility, accept dividend variability in weaker cycles, and focus on the quality and longevity of the underlying asset base.
The company's copper expansion is a significant shift underway, with copper, aluminium, and lithium contributing more than half of Rio Tinto's underlying EBITDA in the first half of 2026. This milestone marks a landmark change in the company's earnings composition, moving beyond its traditional iron ore focus. Oyu Tolgoi, one of the most consequential assets in global mining, is expected to reach production levels of approximately 500,000 tonnes of copper annually by 2028, positioning it as the world's fourth-largest copper mine by 2030.
The success of Oyu Tolgoi's underground block cave operations has validated Rio Tinto's projected production trajectory through 2036. Other copper projects, including Resolution and Winu, add optionality to the company's exposure in this commodity. With a focus on long-duration income and commodity growth, Rio Tinto presents an attractive opportunity for investors willing to hold onto their shares through market fluctuations.
