About the data
Kadoa discovers each new quarterly or annual report as it is published, extracts mine-level production from PDF and spreadsheet reports, then normalizes commodity names and units so volumes are comparable across companies that report in different measures. Newly extracted facts retain the original source value, report location, and transformation history.
Coverage is 12,000 records across 67 companies and 66 commodities. Open data under CC BY 4.0. Start with the production data, companies, or commodities.
