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 (% Li2O)	Contained (Mt LCE)	As at
Measured	—	—	—	—
Indicated	182.10 Mt	1.15% Li2O	5.18 Mt LCE	30 June 2023
Inferred	35.30 Mt	1.19% Li2O	1.04 Mt LCE	30 June 2023
Total Resources	52.80 Mt	1.18% Li2O	1.54 Mt LCE	30 June 2023
Proved	0.40 Mt	1.22% Li2O	0.01 Mt LCE	30 June 2023

Total Reserves	164.60 Mt	1.15% Li2O	4.68 Mt LCE	30 June 2023

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.
