⚠ One Discovery Is Not a ProgrammeModerate threat

Barrick Mining (B) — threat to the moat

Fourmile is exceptional, still years from production, and it is being asked to answer a replacement problem that arrives every single year.

Fourmile is, by the numbers Barrick has published, one of the most significant gold discoveries of the century — conceptual production of some 600,000 to 750,000 ounces a year at all-in sustaining costs around $850 to $900, against a company average currently near $1,637.

Rising, but a small line next to $1.2bn of quarterly capex.

The difficulty with celebrating it is what it implies about everything else. A company producing 3.26 million ounces a year1 needs to replace that much annually, and it is pointing at one deposit, still years from production, as the answer. A pre-feasibility study is due in 2028 and a decline is being driven; first meaningful output is later still. Between now and then the treadmill does not pause.

Exploration is also the most deferrable expense in mining, which is why it gets cut precisely when the industry can least afford to cut it. Barrick's programme is serious — 20 rigs and roughly 120 kilometres of directional drilling planned at Fourmile alone in 2026 — and it is concentrated on a single district in a single country.

The offsetting point is that concentration is deliberate: drilling next to a known orebody is far more likely to succeed than drilling somewhere new, and Nevada is the best jurisdiction the company operates in.

The number to watch is ounces added by the drill bit, outside Fourmile. A programme with one asset in it is a discovery, not a replacement strategy.
