Tailings storage facility inventory profile for metals and mining

Measurement answer

What this metric measures

Reports tailings storage facility inventory consequence classification, tailings storage facility inventory construction method, tailings storage facility inventory current amount of tailings stored for metals and mining. The record keeps 11 defined fields, applicable categories, units, period and boundary together.

Structured table — field-level units
Reporting basis
Use the reporting period declared for the result; point-in-time fields use the stated measurement date.
Aggregation
Do not infer an aggregate across unlike fields. Combine results only when populations, periods, boundaries, units and methods match.

Value structure

Dimensions and units

Unit
Structured table — field-level units
Reporting basis
Use the reporting period declared for the result; point-in-time fields use the stated measurement date.

Unit meaning: Use the field-level unit and scale declared for each value; the taxonomy type does not fix a universal unit.

Table fields and units

  • Tailings storage facility name
  • Tailings storage facility inventory consequence classification (narrative or categorical response)
  • Tailings storage facility inventory construction method (narrative or categorical response)
  • Tailings storage facility inventory current amount of tailings stored (mass; reporter-declared unit and scale)
  • Tailings storage facility inventory date of most recent independent technical review (narrative or categorical response)
  • Tailings storage facility inventory location (narrative or categorical response)
  • Tailings storage facility inventory material findings (narrative or categorical response)
  • Tailings storage facility inventory maximum permitted storage capacity (mass; reporter-declared unit and scale)
  • Tailings storage facility inventory mitigation measures (narrative or categorical response)
  • Tailings storage facility inventory operational status (narrative or categorical response)
  • Tailings storage facility inventory ownership status (narrative or categorical response)
  • Tailings storage facility inventory site specific eprp (narrative or categorical response)

Published dimensions

  • Tailings storage facility name
  • Reporting period or measurement date
  • Metals and mining reporting boundary
  • Geography or business segment where material
  • Measurement method and estimation status

Disclosure form

No single formula

Report the specified field or fields for land, habitats, living systems or ecological dependencies and effects with their stated units, boundary, period and method notes. No universal arithmetic identity is supported without a method-specific population and aggregation rule.

Verified sources

Evidence and status sources

Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Source-edition basis: Sustopedia industry-based measurement profile, 2024 taxonomy-aligned edition (7 November 2024).

  • Values for every applicable field: Tailings storage facility inventory consequence classification; Tailings storage facility inventory construction method; Tailings storage facility inventory current amount of tailings stored; Tailings storage facility inventory date of most recent independent technical review; Tailings storage facility inventory location; Tailings storage facility inventory material findings; Tailings storage facility inventory maximum permitted storage capacity; Tailings storage facility inventory mitigation measures; Tailings storage facility inventory operational status; Tailings storage facility inventory ownership status; Tailings storage facility inventory site specific eprp.
  • Field-level unit, scale, currency or response type where applicable.
  • Reporting period or measurement date.
  • Organizational, operational and value-chain boundary, including exclusions.
  • Estimation, restatement, conversion and method-edition notes.

Record-specific limitations

  • Comparisons require compatible populations, periods, boundaries, units, category definitions and measurement methods.
  • Use the field-level unit and scale declared for each value; the taxonomy type does not fix a universal unit.
  • No universal arithmetic identity is asserted; retain every field and its method context.

Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.

Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
