Jupiter Mines Reports 21% Production Growth as Manganese Prices Pressure Earnings

Highlights:

• High-grade manganese production surged 21%, but weaker prices overshadowed operational gains.

• Quarterly EBITDA declined 34%, exposing growing pressure on Tshipi's profitability.

• Attributable cash fell to AU$52.7 million, raising attention towards future shareholder returns.

Jupiter Mines Reports Mixed Quarterly Performance

Jupiter Mines Limited (ASX: JMS), an Australian manganese mining company, reported contrasting operational and financial results in its September-quarter update released on 30 October 2026. The company also published its FY2026 preliminary financial results and dividend announcement on 28 August 2026, followed by its annual report on 30 September 2026. Despite stronger high-grade manganese production, declining commodity prices and rising transportation expenses weighed on profitability.

Production Growth Supports Mining Operations

Jupiter holds a 49.9% interest in South Africa's Tshipi manganese mine, where high-grade production increased 21% year-on-year to approximately 790,130 tonnes.

Key operational developments included:

• Total manganese production reached 823,800 tonnes, compared with 829,798 tonnes a year earlier.

• Ore sales increased 1% year-on-year to approximately 848,566 tonnes.

• Average production costs rose 11% annually to US$2.51 per dry metric tonne unit.

• Graded ore mining volumes increased 19% compared with the corresponding quarter.

These figures reflect the mine's overall performance rather than Jupiter's proportional ownership.

Lower Manganese Prices Weigh on Earnings

Tshipi's quarterly EBITDA declined to AU$22.5 million from AU$34.2 million in the preceding quarter, while net profit fell to AU$15.6 million. Average realised manganese prices decreased 10% quarter-on-quarter to US$4.44 per dry metric tonne unit, reflecting weaker Chinese demand and elevated supply.

Meanwhile, Jupiter's attributable cash declined from AU$73.9 million to AU$52.7 million, influenced by dividend distributions and working capital requirements. For FY2026, Jupiter reported group net profit of AU$37.6 million, compared with AU$39.9 million previously.

Outlook: Can Stronger Output Offset Market Weakness?

Jupiter's prospects remain closely connected to manganese prices, Chinese steel production and international shipping costs. Although operational efficiency and established export infrastructure support its competitive position, persistent pricing weakness could constrain earnings recovery. Looking ahead, improving steel demand, disciplined expenditure and stable manganese prices will be important for sustaining profitability and future shareholder distributions.
