Current R&R by category
Whole-project rollup at the latest vintage per category: printed project-level rows are preferred, and mining areas are summed (tonnes-weighted grade) only where the issuer prints no project-level row. Per-area and per-source detail in the Current R&R table below.

Cutoff 54.00 % Fe — Cut-off grade assumption from the source statement.
@ A$ 106/t — Metal price assumption used to derive this estimate.
excl — Stated Resources are EXCLUSIVE of Reserves — they sit on top of the reserve, so decks quoting inclusive resources will show a larger figure (inclusive = this row + the converted reserve).
attrib — Figures are net to the issuer's ownership interest as reported (attributable basis) — NOT 100% of the project.
QA notes:
QA WARN: mining_area 'WAIO Total' looks like a table SUBTOTAL line, not a leaf area — approving it alongside the leaf areas double-counts. Reject it (or reject the leaves) before approval.
QA FIX (claude-agent-qa): printed Total line is the whole-project figure, not a mining area — area cleared per the whole-project-label convention.

QA notes:
QA WARN: mining_area 'WAIO Total' looks like a table SUBTOTAL line, not a leaf area — approving it alongside the leaf areas double-counts. Reject it (or reject the leaves) before approval.
QA FIX (claude-agent-qa): printed Total line is the whole-project figure, not a mining area — area cleared per the whole-project-label convention.
Rows are hierarchical, not additive — do not sum a column across rows. Whole-project rows (Area “Total”) already contain the indented named-area rows beneath them, and an issuer's printed per-deposit total can itself contain other listed areas. All derived totals and rollups on this site already exclude the overlapping rows.
Figures are on a 100% project basis unless a row carries the attrib chip; BHP GROUP LIMITED holds 85.0% of this project.
