Why capital structure is the boring factor that decides outcomes
A junior miner exists to convert capital into discovery, discovery into resources, resources into development, development into production. At every stage, the primary risk is not that the geology will fail — it's that the company will run out of cash before it gets to the next milestone, and will have to raise money at punitive terms to survive. Capital structure is how we score whether a company is positioned to avoid that outcome.
Four inputs drive the capital score. Fully-diluted share count relative to the asset (bigger assets can carry bigger share counts). Warrant overhang — how many out-of-the-money or near-the-money warrants are outstanding and what's their strike pattern. Dilution history — has the company raised at progressively better or worse terms over its history. And working-capital runway — how many months of general and administrative expenses plus exploration/development spend can current cash cover at the current burn rate.
Why producers can show up on a cap-table list
Equinox Gold and Franco-Nevada on this list are worth thinking about. Producers generate cash flow, which means the burn-rate input flips from negative to positive. But producers also carry debt, and a producer with $500M of debt against $600M of EBITDA has a structurally different capital posture than a debt-free junior with $10M of cash and a 3-year runway. The framework treats both on the same 5-point scale because both can be bankrupted by the same structural problem: running out of liquidity before the next milestone.
Mako Mining is the more interesting case on this list. Mako is the only TSX-V junior scoring 5/5 on capital — a rarity on an exchange where most names are pre-revenue and funded through successive equity raises. The difference is San Albino's operating cash flow, which converts Mako from a capital-consuming explorer into a self-funding producer-developer. That category — TSX-V producer-developer — is small and worth tracking specifically.
The low-cap-score trap
The worst combination in junior mining is a high composite score on geology and catalyst combined with a low score on capital. Those companies usually look like "a great project waiting for the right financing" — but the right financing rarely arrives, and when it does, it arrives at terms that transfer most of the remaining value to the financier. Check the capital score before anchoring on P/NAV or catalyst math. A 2/5 capital score in combination with a low P/NAV is almost always a value trap, not a bargain.
How the list evolves
Capital scores move most often. A single clean financing can upgrade a name from 2/5 to 3/5 or 3/5 to 4/5 in one quarter. Similarly, a punitive raise can degrade a 4/5 to 3/5 overnight. Expect composition changes each quarter as cap tables shift with financing activity.
