GOLD × MINERS

When gold rises, which miners gain the most?

A miner earns the gap between the gold price and its costs, so when gold rises its profits can grow several times faster. But costs, hedges, by-products, debt and politics decide how much of that reaches shareholders. This site reads the latest filings of the major producers and royalty companies and ranks them on the same yardsticks, every day.

Is this a market where miners beat gold?

Owning miners instead of gold only pays when these hold. A lit lamp means the condition holds today.

Week to week, miners do amplify gold: GDX's 52-week beta is 1.80x now and has stayed above 1 for most of the past 20 years. Over whole years it is another story: in the 13 years gold rose 5% or more, GDX beat gold in only 5, and GDX ÷ gold is still 62% below where it started in 2006. Cost inflation, share issuance and mining taxes have eaten much of the leverage over time. Miners pay when margins widen faster than costs, which is what the conditions above check.

Should rise is calculated from results: how much the per-ounce margin grows when gold rises 10% (after hedges, by-products and price-linked royalties), scaled up for net debt (enterprise value ÷ market value), assuming the market keeps valuing the company on the same multiple. Actually moved is the two-year beta to gold × 10%. Quality is a 0–100 score for reserves, balance sheet, jurisdiction, delivery and cost control.
