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
Measured	47.55 Mt	0.19 g/t	0.29 Moz	30 June 2025
Indicated	54.41 Mt	0.23 g/t	0.41 Moz	30 June 2025
M&I = Measured + Indicated (overlaps both)	101.97 Mt	0.21 g/t	0.70 Moz	30 June 2025
Inferred	84.27 Mt	0.14 g/t	0.37 Moz	30 June 2025

Total Reserves	376.52 Mt	0.28 g/t	3.39 Moz	30 June 2025

M&I is the issuer's printed Measured + Indicated subtotal — it overlaps the Measured and Indicated rows and is never added alongside them; the Total rows and every rollup already exclude it.

QA note (t92a a6): indicated Au NULL 52,357,000 t @ 0.23 g/t / 388,670.3753 oz is SOUND (self-recompute 387,163 oz, -0.39%; implied grade 0.2309 g/t). The three approved leaves total 11,888,000 t / 119,825.83 oz, leaving 40,469,000 t / 268,844.5 oz (8,362.0 kg) at an implied 0.2066 g/t uncaptured — the MWS tailings-dam line, absent from the book (only MWS WRD, West Wits WRD and West Wits tailings were extracted).

QA notes:

AUTO UNIT-FIX: grade 0.13 × 1000 → 130.00 g/t — recomputed contained reconciles to the document's reported figure (unconverted ppm/ppb unit). Confirm in review. QA WARN: recomputed contained 341736393.9198 oz vs reported 354236925.6931430893925016126 oz (3.53% disagreement)
QA FIX (claude-agent-qa): unit auto-fix multiplied the grade x1000 to reconcile with contained figures that were themselves x1000 from the kg conversion bug — both divided back; grade now matches the printed table.
t92a note-hygiene: the dangling AUTO UNIT-FIX suggestion is WRONG — stored grade 0.13 g/t is correct (81,763,000 t @ 0.13 = 341,736 oz vs printed 354,236.93, inside 2dp grade print); do not apply the x1000 fix (t92 a6)
