Reporting assumptions

These choices persist and are added to shared URLs.

Ownership basis

Show the full project inventory before ownership adjustment.

Display scale

Display contained quantities in millions of ounces or tonnes.

Resource treatment

Normalise Resources to exclude Reserves: where a project is flagged inclusive, net Reserves out of Resources so the figure is additional Resources beyond Reserves. Unknown-convention rows are shown as stated.

Resource total

Total Resource includes Inferred (JORC convention). Totals are re-derived from category rows wherever the document discloses them.

Recovery basis

Show the issuer's headline recoverable figure as reported. Lithium-brine reserves already have the brine-processing recovery factor applied; everything else is shown as stated.

Commodity view

Primary view: each commodity in its own contained unit (oz / t).

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.

Category	Tonnes (Mt)	Grade (g/t Au)	Contained (Moz Au)	As at

Sub-category rows are as disclosed (no Reserves-treatment netting); the Total rows honour the Resources treatment and Inferred-policy toggles, so components may not sum to the Total.

QA notes:

QA WARN: identical figures appear under ANOTHER area label of this project in the same document — likely one printed estimate stored twice (a summary/grouping line duplicating its leaf). Keep one copy; reject the relabelled twin. QA WARN: this category row reuses the Total row's exact tonnage with a DIFFERENT grade — likely a narrative-splice composite (category figures glued onto total tonnes); verify a printed line carries this exact tonnes/grade pair.

QA WARN: mining_area 'EL28282 Open Pit' never appears beside project 'Central Tanami Project' in the document text (nor as a sub-row label) — an invented area label re-presents a whole-project row as a phantom leaf (live t52: Brucejack 'Underground' silver reserves; the print has no such split).

QA fix: figures correct - printed Appendix 1 p.16, tenement ML33760 row 'Open Pit', Measured column = 11 kt @ 1.5 g/t for 1 koz - but the area label lost its tenement: this line sits in the ML33760 row-block (Southern/Bouncer/.../Hurricane & Repulse), and every other tenement's leaves are stored tenement-qualified ('ML(S)167 Open Pit' etc).
