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	1.63 Mt	3.28 g/t	0.17 Moz	30 June 2026
Indicated	15.45 Mt	2.96 g/t	1.47 Moz	30 June 2026
M&I = Measured + Indicated (overlaps both)	9.50 Mt	2.95 g/t	0.90 Moz	30 June 2026
Inferred	13.13 Mt	2.56 g/t	1.08 Moz	30 June 2026
Total Resources	17.81 Mt	2.93 g/t	1.68 Moz	30 June 2026
Proved	1.35 Mt	2.52 g/t	0.11 Moz	30 June 2026
Probable	11.06 Mt	2.64 g/t	0.94 Moz	30 June 2026
Total Reserves	12.41 Mt	2.63 g/t	1.05 Moz	30 June 2026

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.

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.

Dotted tonnes/grade are derived under the active Resources treatment: tonnes are netted of (or grossed by) the reserve tonnage alongside contained, and grade is re-derived as netted contained ÷ netted tonnes — not the published figures.
