Every number sourced. Every change proven.
Verified operational data for 156 producing mining companies across 12 commodities. Production, costs, grades, and prices — sourced from primary documents, tracked over time.
The opportunity
Why miners, not commodities
When silver rises from $20 to $30 — a 50% move — a miner producing at $10/oz sees their margin double from $10 to $20. The commodity moved 50%. The margin moved 100%.
And the miner keeps earning that margin. Higher margins compound into stronger balance sheets, expanded production, and reinvestment.
But not all miners benefit equally. Some grow production while others shrink. Some cut costs while others see costs rise. Operational differences determine which miners actually benefit from commodity cycles.
Finding those differences requires looking at the operations. That's what ProveMines is built for.
The problem
Mining data is broken
Search for “Newmont AISC 2024” and you'll find ten different numbers from ten different sources. None link to the original filing. None track definitions.
Scattered across exchanges
156 companies file with 7 different exchanges. Hundreds of PDFs every year — SEC, ASX, TSX, LSE, JSE filings scattered across dozens of websites.
Definitions differ silently
AISC can mean six different things depending on the company. Net of by-product credits? Including corporate G&A? The number looks the same. The meaning isn't.
Methodology changes break trends
When a company changes how it calculates a cost metric, the number shifts — but the change is buried in footnotes. Year-over-year comparisons break silently.
The dataset
We read every report
Hundreds of annual reports, SEC filings, and exchange announcements. Every operational metric extracted, every definition tracked, every number linked to its source.
Production
Gold produced, copper sold, iron ore shipped. Physical output tracked in canonical units across all producers.
Costs
AISC, C1 cash cost — commodity-specific, definition-tracked, currency-preserved. The numbers that determine margins.
Prices
Realized commodity prices as reported by each company. The revenue side of the margin equation.
Efficiency
Ore grades, recovery rates. The underlying metrics that signal whether operations are improving or deteriorating.
Verification
Don't trust us. Verify it.
Every datapoint links to its original source — the company's own filing. Not a news article. Not an aggregator. The exact page and verbatim quote.
The workspace
Three ways to explore
Each view answers a different question. All powered by the same verified dataset with built-in break detection and proof linking.

12 commodities. 156 producers.
Mining companies produce homogeneous products. Gold is gold. Copper is copper. The only difference is how they operate — making cross-company comparison uniquely meaningful.
Differentiation
The operational layer that doesn't exist elsewhere
Financial terminals have financial data. They don't track how each company defines AISC. They don't flag when definitions change. They don't link to source pages.
