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 (% Li2O)	Contained (Mt LCE)	As at
Measured	—	—	—	—
Indicated	70.00 Mt	1.01% Li2O	1.75 Mt LCE	28 Nov 2024
Inferred	4.10 Mt	0.76% Li2O	0.08 Mt LCE	28 Nov 2024

Total Reserves	46.30 Mt	0.99% Li2O	1.13 Mt LCE	01 July 2025

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.

Cutoff 0.45% Li2O — Cut-off grade assumption from the source statement.
inc — Stated Resources are inclusive of Reserves. Set Resources: Excl. Reserves to net them out.

QA notes:

QA INFO: recompute differs 1.25% from the printed contained figure, but the printed tonnes/grade/contained are only good to ±6.63% (rounding granularity) — treated as reconciled.
t83 print round (p4): print-exact: doc 6a6bb390 Table E.3 prints "Chewy Inferred 0.5 0.79 46 1.33 4,000 23 51,100 7%" = stored 500,000 t @ 0.79% Li2O / 4,000 t Li2O reported / 9,892 t LCE; Chewy "Sub Total 6.0 0.92 49 0.82 55,000" = 51,000+4,000 exactly. RESOLVES THE 4.878%/7.878% SPLIT SHORTFALL: the missing leaf is a SIXTH inferred deposit, "B. Crumbs Inferred 0.3 0.87 379 0.74 2,400 105 231,650 100%" (0.3 Mt @ 0.87% Li2O = 2,400 t Li2O = 5,935.2 t LCE, Ta2O5 105 t / 231,650 lb) — never extracted. Adding it closes the gap (28,650 + 2,400 = 31,050 t Li2O vs consolidated 31,100 t; 3.9 + 0.3 = 4.2 Mt vs 4.1 Mt printed). B. Crumbs carries no Indicated (Table E.3 prints "Indicated 0.0 0.00 0 0.00 - 0 - 0%"), which is why the indicated splits already foot to 70.0 Mt / 709,100 t Li2O. Recommend ingesting the B. Crumbs inferred row; the stored split set is incomplete, not wrong.
