Rank View

Rank starts with a KPI. Select gold production, AISC, copper sold, realized price, recovery rate — any of the 102 metrics in the dataset. Then pick a time period: a point-to-point comparison (2020 to 2024) or a range analysis (average YoY over 2020–2024).

The workspace computes the change for every company that has data for that KPI and period, then sorts them from best to worst. The result is a leaderboard — not of who is biggest, but of who improved the most.

For production KPIs (gold produced, copper sold, ore milled), a positive change is good. For cost KPIs (AISC, C1 cash cost), a negative change is good — costs going down is improvement.

Rank handles this automatically. Cost KPIs have their sign flipped for display: a 10% decrease in AISC shows as +10% (green). A 10% increase shows as -10% (red). You never have to think about whether “up” or “down” is good for a given metric. Green is good. Red is bad. Always.

Sorting works the same way. The company at rank #1 always had the most favorable change, whether that means the biggest production increase or the deepest cost cut.

When a company changes how it calculates a metric — switching from “AISC net of by-product credits” to “AISC excluding corporate G&A,” for example — the year-over-year change becomes meaningless. The number went up, but not because costs increased. The definition changed.

Rank shows these definition breaks inline. A small indicator appears next to any value where the underlying definition changed between the compared periods. You can click to see both the old and new definition.

The “comparable only” filter goes further: toggle it on and the ranking excludes any company whose definition changed during the selected period. What remains is a clean ranking where every percentage change is an apples-to-apples comparison.

You can select multiple KPIs at once. Each KPI becomes a column in the rank table. Click any column header to re-sort by that metric. This lets you see, at a glance, whether the companies that grew production the most also managed to cut costs — or whether they traded one for the other.
