Coverage is shown as a chain of evidence, not one ambiguous percentage. The active universe is the exchange-synced listed mining population; published coverage is the narrower set with at least one estimate that passed human QA. Linked cross-listings count as one issuer in the headline and share their approved evidence in every exchange row.
Each checkpoint is cumulative: downstream evidence carries an issuer through earlier operational stages. Full-year scan proof is reported separately above and is never inferred from an empty announcement table.
Canonical active issuers across all supported exchanges.
Full-year scan proof or downstream evidence that a disclosure was located.
At least one announcement passed screening or reached a later stage.
At least one source document is retained with provenance.
A document was processed, including legitimate zero-row outcomes.
At least one extracted row received an approve/reject decision.
At least one estimate passed human QA and is visible publicly.
Mutually exclusive current reasons for active canonical issuers without approved rows. Human audit outcomes take precedence over inferred pipeline state.
Announcements were scanned, but none passed the R&R relevance screen.
At least one document was processed but no approved estimate is available.
A source document is archived but extraction has not completed.
Extraction produced rows, but human QA rejected every row for this issuer.
A complete 365-day source window returned no R&R-relevant candidate.
This screen layout is stored in the URL. Exports retain their full evidence and assumptions columns.

Exchange rows count active listings, while the headline counts canonical issuers. A linked secondary is covered when any listing in its issuer group has approved rows. Last recorded discovery: 28 Aug 2026. Last ingestion run: 28 Aug 2026 (success). See the methodology for how figures are extracted, cross-checked and QA'd.
