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
Measured	12.40 Mt	0.73 g/t	0.29 Moz	30 June 2026
Indicated	45.60 Mt	1.75 g/t	2.57 Moz	30 June 2026
M&I = Measured + Indicated (overlaps both)	58.10 Mt	1.53 g/t	2.86 Moz	30 June 2026
Inferred	32.30 Mt	1.50 g/t	1.59 Moz	30 June 2026
Total Resources	19.30 Mt	2.21 g/t	1.37 Moz	30 June 2026
Proved	12.40 Mt	0.73 g/t	0.29 Moz	30 June 2026
Probable	29.10 Mt	1.46 g/t	1.37 Moz	30 June 2026
Total Reserves	41.50 Mt	1.24 g/t	1.66 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.
