Long-term supply secured as South Africa mine investment resumes

On March 2, 2026, Rio Tinto approved an investment of approximately R8.5 billion (US$473 million) to develop the Zulti South mineral sands deposit at its Richards Bay Minerals operation in South Africa, officially ending a suspension that had been in place since January 2020. The project investment extends mine operations to 2050 and secures long-term supply of key feedstocks, with China Harbour Engineering Company appointed as contractor for engineering, procurement, and construction. The company also updated its market disclosures, confirming ordinary shares, treasury holdings, and dual-listed company share issuance, including Special Voting Shares and DLC Dividend Shares to align UK and Australian listings, as well as its ongoing NYSE ADR program, though price action has remained under broader selling pressure.

Mixed momentum signals as technical boundaries prompt caution

Technically, Rio Tinto is trading below the MA-20 ($7,163.90) but remains above the MA-50 ($6,641.06) and MA-200 ($5,263.22). Immediate support is identified at the Ichimoku Kijun level of $6,877.00. Momentum indicators are mixed: the MACD continues to show strong bullish momentum, while the ADX suggests further selling. The RSI is neutral-to-bullish, though the Stochastic RSI indicates oversold, and the Commodity Channel Index signals overbought conditions. Bull/Bear Power is also in overbought territory, pointing to recent buyer dominance, but the Awesome Oscillator still supports a medium-term uptrend. However, conflicting oscillator signals and high intraday volatility underscore short-term caution.

High upside probability as volatility confines RIO to narrow range

For the next five trading days, RIO is expected to trade within a typical volatility band between $7,010.00 and $7,295.00. There remains a high likelihood, above 80%, of a price increase, while a decline is considered less probable. Most scenarios anticipate sideways movement in the $7,010.00 – $7,295.00 corridor. A sustained break above $7,295.00 could trigger further upside if buying momentum returns, while a close below $7,010.00 would likely confirm deeper correction risk amid recent short-term weakness.

Viktoras Karapetjanc, expert at Traders Union, sees Rio Tinto’s latest strategic investment and long-term mine extension as strengthening the company’s fundamental outlook. He believes that, despite near-term volatility and mixed technical signals, medium- and long-term trends remain positive. Macro sentiment is also supported by clarity around shareholder structures and an active ADR program. In his view, the stock is well positioned if it can stay above support in the $7,010.00 to $7,295.00 range. "The recent Zulti South investment signals confidence in future growth, and I expect bullish sentiment to prevail as long as Rio Tinto holds above key support levels."

Previously it was reported that Rio Tinto Group maintained strong bullish momentum, trading firmly above key moving averages with positive MACD and ADX signals, while the daily Ichimoku Kijun level provided immediate support. However, the stock showed signs of being overbought with high volatility, as RSI and other oscillators indicated potential vulnerability to short-term profit-taking, though the prevailing trend remains upward unless support fails.
