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

Total Reserves	13.59 Mt	1.57 g/t	0.69 Moz	31 Mar 2026

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.

QA notes:

QA WARN: unrecognised source metal label 'Ounces' for Au — verify the commodity mapping. QA BLOCK: recomputed contained 306698.8318 oz vs reported 153000 oz (100.46% disagreement)
QA annotate (t98v, a5.txt): Stockpile grade defect, not a recovery convention. The Mineral Resources table prints "Stockpiles 7,338 1.3 153 - - - - - - 7,338 1.3 153" under CAROSUE DAM, but the SAME announcement's Ore Reserves table prints the SAME stockpile with the SAME tonnes and the SAME ounces at a different grade: "Stockpiles 7,338 0.6 153". 153koz over 7,338kt implies 0.6485 g/t, which rounds to the reserve table's 0.6 and cannot round to 1.3. Ounces are identical in both tables and reserve note 3 says ounces "do not include allowances for processing losses", so this is not an in-situ vs recovered split — one of the two printed grade cells is simply wrong, and the arithmetic backs the reserve one. Row stands as printed (the resource table is its source); operator FIX candidate: grade=0.6.

QA notes:

QA WARN: unrecognised source metal label 'Ounces' for Au — verify the commodity mapping. QA BLOCK: recomputed contained 864173.4869 oz vs reported 727000 oz (18.87% disagreement)
QA annotate (t98v, a5.txt): Printed "Underground 4,095 2.4 319
16,156 2.3 1,185
10,338 2.6 727
30,588 2.4 2,232" (CAROSUE DAM, Mineral Resources). The inferred cell does not close: 10,338kt x 2.6 = 864koz against the printed 727koz (implies 2.187 g/t), and print granularity is ~2% against a 15.9% gap. Tonnes and ounces cross-foot at three levels — UG measured+indicated+inferred = 30,589kt/2,231koz vs the printed 30,588/2,232; Carosue sub-total inferred 21,063kt/1,209koz = surface 10,725/482 + UG 10,338/727; and TOTAL KALGOORLIE inferred 408,421kt @ 1.7 for 22,728koz reconciles exactly (implied 1.731) with Carosue's 1,209koz inside it. So the ounces are right and the Carosue inferred grade cells (UG 2.6, sub-total 2.0 vs implied 1.785) are the print's defect.
