Perseus Mining Limited

The Business

Perseus operates the Edikan and Sissingué mines in Ghana and Côte d'Ivoire, the Yaouré mine also in Côte d'Ivoire, and is building a fourth mine, Nyanzaga, in Tanzania. Group production sits around 400-500 thousand ounces a year, sold at spot with no meaningful hedging. The business carries no debt and funds all growth capital from its own balance sheet. What separates Perseus from single-asset miners is diversification: four mines across three jurisdictions means no single government or ore body determines the outcome.

Recent Performance

Revenue reached US$1,484 million in FY26, up sharply on record realised gold prices of roughly US$3,700 an ounce. The shares have re-rated hard over the past year as gold ran from the low US$2,000s to above US$4,600 today. Costs rose too, with all-in sustaining costs up 42% as royalties, which scale with the gold price, took a larger bite. Margins nonetheless held near 58%, and the share price has moved well ahead of what a disciplined read of production and price assumptions can support.

Outlook

Earnings are expected to grow over the next two years as Nyanzaga ramps from a half-year contribution toward its 200,000-ounce steady state, before growth moderates as the gold price assumption normalises from today's elevated level toward a more conservative terminal price. Group production climbs roughly 50% by FY28 as the new mine comes online. Margins are expected to compress gradually over the forecast period as royalty rates bite and lower-grade ore enters the mix, though they remain comfortably above levels needed to sustain the balance sheet through a downturn.

Key Risks

A reversion in gold toward the mid-US$2,000s, well within the historical trading range, would materially reduce earnings and compress margins across the portfolio. A delay at Nyanzaga, not uncommon for greenfield African mine builds, would open a production gap in the near-term outlook and push the growth story out by a year or more. Rising royalty rates in Ghana and Côte d'Ivoire, plus the eventual exhaustion of the Edikan and Sissingué mines after FY33, add further pressure and will require exploration success or acquisitions to offset.

What to Watch

The thesis-defining event is the first gold pour at Nyanzaga, expected January 2027, which will confirm whether the new mine delivers on time and de-risks the production growth story.

• January 2027 Nyanzaga first gold pour — on-time delivery removes the largest single execution risk in the near-term outlook.
• Quarterly Central bank gold purchase data — sustained buying at an elevated pace across consecutive quarters would support the case for a structurally higher gold price.

Company Description

Perseus Mining is a gold producer operating four mines across three African countries. Edikan (Ghana) and Sissingué (Côte d'Ivoire) are mature, lower-growth assets nearing the back half of their reserve lives. Yaouré (Côte d'Ivoire) is the current production anchor at around 150-160 thousand ounces a year. Nyanzaga (Tanzania) is under construction and due for first gold in January 2027, holding 4.1 million ounces of reserves, roughly 60% of the group total, and is expected to be the lowest-cost, longest-life asset in the portfolio once ramped.

Where the Growth Is

Nyanzaga is the growth story. It contributes nothing to FY26 production but is forecast to reach 35-40% of group output by FY29, ramping from 45,000 ounces in its first half-year to a 200,000-ounce annual run rate by FY30. That ramp drives roughly a 50% uplift in group production and, because Nyanzaga's costs run below the existing portfolio average, should pull the group's blended cost per ounce lower over the next three years.

Competitive Position

Perseus's advantage is reserve depth and spread. Group reserves of 7.0 million ounces, up 40% year-on-year through exploration success and the Nyanzaga acquisition, support a 16-year weighted mine life, longer than most mid-tier African peers. Operating across three jurisdictions rather than one limits exposure to any single government's royalty policy or political risk, a real consideration given the sector's history of sovereign disputes. These advantages are durable for perhaps five to seven years, the horizon over which reserves, permits and cost positions are reasonably well known; beyond that, replacement of the older mines (Edikan and Sissingué both wind down through the early 2030s) depends on exploration success that cannot yet be underwritten.

Management & Capital Discipline

Over the past cycle, management sold the non-core Meyas Sand asset for US$260 million and used the proceeds alongside cash on hand to fund the US$423 million OreCorp acquisition that brought Nyanzaga into the portfolio, a recycling exercise that looks disciplined in hindsight. Shareholders have also received capital returns through dividends and an approved A$350 million buyback. The honest caveat: the chief executive has under a year in the role and the chief operating officer under three months, so the current team has delivered on guidance so far but has not yet been tested through a full commodity downturn or a major operational setback.

Financial Position

Perseus carries zero debt and held US$1.03 billion in cash at the last balance date, against a market capitalisation that implies the market is paying primarily for the mines, not the cash. That balance sheet comfortably funds the remaining Nyanzaga construction spend without needing to raise equity or debt, and would sustain the company through a prolonged period of low gold prices given all-in sustaining costs remain well below spot even in a downside scenario.
