Company Business

Capricorn Metals (ASX:CMM) produces gold at Karlawinda, located in the Pilbara region of Western Australia. Mining, ore processing and gold sales underpin its operating cash generation. The Karlawinda Expansion Project has added processing infrastructure intended to accommodate higher ore throughput.

The company also owns the Mt Gibson Gold Project in Western Australia’s Mid-West region, where development planning, environmental approvals and exploration activities are progressing. Mt Gibson is not yet an operating mine.

Recent Development

In early October 2026, Capricorn Metals (ASX:CMM) disclosed September-quarter Karlawinda production of 31,218 ounces, compared with 30,437 ounces in the June quarter. Material mined reached 4.439 million bank cubic metres, while the processing plant treated 1.133 million tonnes of ore at a head grade of 0.94 grams per tonne and a recovery rate of 91.7%.

The company confirmed that construction of the Karlawinda expansion was completed in September 2026 on schedule and within budget. Capricorn stated that processing capacity had increased to 6.5 million tonnes per annum, with a longer-term production rate of approximately 150,000 ounces annually envisaged after commissioning and ramp-up.

At Mt Gibson, detailed engineering had been completed and major contracts finalised. Federal environmental approval had been obtained, while the Western Australian Part IV assessment and related secondary approvals remained in progress. The company spent AUD 2.1mn on Mt Gibson development activity in the quarter, principally early procurement and contract preparation.

Financial Performance and Sector Context

Capricorn Metals (ASX:CMM) reported cash and gold holdings of AUD 535.0mn at 30 September 2026, compared with AUD 507.0mn at 30 June. The underlying quarterly cash build was AUD 62.2mn before AUD 42.7mn of combined Karlawinda expansion and Mt Gibson capital expenditure and the AUD 8.5mn cash component of the Big Springs divestment.

For FY26, Capricorn reported AUD 769.3mn in gold sales revenue from 123,096 ounces sold, with underlying EBITDA of AUD 483.6mn, up 63% year on year. Underlying profit after tax was AUD 327.2mn, up 59%, while Karlawinda produced 123,589 ounces at an all-in sustaining cost of AUD 1,629 per ounce. Its FY27 guidance is 137,000–147,000 ounces at AUD 1,900–2,100 per ounce, reflecting a different planned operating and cost profile following the expansion.

Gold prices, royalties, diesel, labour, mining volumes and plant availability affect operating economics.

Risks to Consider

Capricorn Metals (ASX:CMM) faces commissioning and ramp-up risk at Karlawinda, including potential disruptions to throughput, recovery and unit costs. Mt Gibson carries permitting, development schedule and capital expenditure risks. Gold price changes, labour availability, inflation and variations in mining conditions may affect financial outcomes.

What to Watch Next

Key milestones include Karlawinda processing rates after the expansion, quarterly ounces produced, all-in sustaining costs and progress against FY27 guidance. Mt Gibson environmental decisions and the timing of any construction commencement remain relevant.
