The MoatThin moat

Barrick is one of the two largest gold miners on earth, and it makes an unusual entry in a study of moats — because a gold miner is very nearly the opposite of a moat business. Warren Buffett's objection to gold is famous: it is an asset that produces nothing, pays no dividend, and compounds no earnings; you buy it only in the hope that someone will pay more for it later. A company that digs the metal out of the ground inherits the deepest flaw of the metal itself — it has no pricing power. Barrick sells its gold at whatever price the world sets that morning; it cannot charge a dollar more than the miner down the road. That single fact, the absence of pricing power, is enough on its own to disqualify most commodity producers from a durable moat.

And yet Barrick is not quite without advantages, and it is worth being precise about what they are and what they are not. What Barrick owns is not a moat around its prices; it is a moat, if the word even applies, around its costs and its assets. The company holds a handful of what the industry calls Tier-One mines — ore bodies so large, so long-lived, and so cheap to run that they simply cannot be reproduced. You cannot build a new Nevada. You cannot conjure another Kibali. These deposits took geological ages to form and decades and billions to develop, and a rival with all the money in the world cannot will one into being where the gold is not. That irreplaceability is the closest thing a miner has to a moat.

The second advantage follows from the first. Because its best mines are cheap to run, Barrick sits in the lower half of the industry cost curve. When the gold price falls, the high-cost miners bleed and shut; Barrick keeps producing at a profit. When the price rises — as it has spectacularly, to records above four thousand dollars an ounce in 2025 and 2026 — Barrick's costs barely move while its revenue soars, and the cash floods in. That operating leverage is real, but notice exactly what it is: leverage to a price the company does not control, not a moat that protects a price it does.

Almost everything else about the business is a treadmill. A mine is a wasting asset; every ounce pulled from the ground is an ounce that must be found again somewhere else, through exploration or acquisition, merely to stand still. A miner that stops replacing its reserves is quietly liquidating itself. So Barrick must run hard just to stay the same size — an exhausting economics that a true moat business, which grows richer simply by existing, never faces.

The company was remade in 2019 by its merger with Randgold Resources, which brought in Mark Bristow¹, a mining executive of unusual discipline, and a culture fixed on cost and cash flow rather than the empire-building ounces that had nearly wrecked the old Barrick. In 2025 it renamed itself from Barrick Gold to Barrick Mining², a nod to a growing copper business — Lumwana in Zambia and the vast Reko Diq project in Pakistan — that gives it a second commodity and a claim on the metal the energy transition needs most.

So why put a near-moatless business in a book about moats? Because the contrast teaches something. Barrick is a well-run, low-cost, asset-rich company that will make enormous sums when gold is high and struggle when it is low, and no amount of operational excellence changes the fundamental truth that it is a price-taker riding a cycle. It is the clearest example in this collection of the difference between a good business and a good moat — a reminder that the two are not the same thing. Own it, if you own it, for the gold and the cash it throws off at the top of the cycle, not for a fortress that isn't there.
