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.

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. “M&I” is the issuer's printed Measured + Indicated subtotal: it overlaps the Measured and Indicated rows and is never added alongside them. 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 57.5% of this project.

attrib — Figures are net to the issuer's ownership interest as reported (attributable basis) — NOT 100% of the project.
QA notes:
QA INFO: inclusive-of-reserves flag cleared — the flag describes resource statements; reserve rows carry none. QA WARN: cross-category subtotal — this total_reserve row on area 'Sulphide' equals the sum of the same area's proved+probable leaves — a per-deposit M&I/P&P-style total (t24 LUN/LUG NI 43-101 class). This can be an authoritative issuer-printed per-deposit total or an unhelpful intermediate subtotal. Verify the printed row: retain explicit deposit totals, but reject derived/unprinted or mid-tier rollups before approval.

QA INFO: inclusive-of-reserves flag cleared — the flag describes resource statements; reserve rows carry none. QA WARN: figures within print rounding of a stored row of the same company/project/area/category under a DIFFERENT as-at date — likely a re-presentation (DFS / annual statement / global MRE restating an already-stored estimate, possibly at coarser rounding). Keep one operative copy; verify supersession before storing both.
