This chart is basically asking one powerful question. When gold miners sell one ounce of gold, how much goes into keeping the mine running, and how much becomes margin?
The green part is AISC, or all in sustaining cost. Think of it as the miner’s full operating bill. Mining, processing, sustaining capital, admin, keeping the engine alive. The gold part is production margin, the money left after those costs. And this is where the story gets spicy.
Back in 2015, miners were fighting for oxygen. Around 76 percent of the gold price was eaten by costs, leaving only about 24 percent as margin. That is not exactly champagne season. It is more like instant noodles and survival mode.
But fast forward to 2024, and the picture changes dramatically. For the first time in this chart, gold price and mining costs split almost evenly. Half cost, half margin. Then 2025 pushes the story further, with margin rising above 55 percent.
And then boom, 2026 Q1 arrives like a heavyweight walking into the ring. Margin share hits 62.9 percent, the highest on the chart, while AISC drops to only 37.1 percent of the gold price.
The cause is simple. Gold prices exploded faster than mining costs. Costs still went up, but gold ran harder. That creates operating leverage. For commodity markets, this is huge. When margins expand like this, miners can generate more free cash flow, repair balance sheets, fund growth, pay dividends, and attract investor attention.
The bigger message is this. A rising gold price does not just lift the metal. It can supercharge the entire gold mining sector.
