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.

Au

Category	Tonnes (Mt)	Grade (g/t Au)	Contained (Moz Au)	As at
Measured	—	—	—	—
Indicated	17.60 Mt	0.30 g/t	0.16 Moz	24 Aug 2026
Inferred	13.20 Mt	0.20 g/t	0.10 Moz	24 Aug 2026

Probable	8.30 Mt	0.30 g/t	0.08 Moz	16 Mar 2026
Total Reserves	8.40 Mt	0.30 g/t	0.08 Moz	16 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.

Cu

Category	Tonnes (Mt)	Grade (% Cu)	Contained (Mt Cu)	As at

Cutoff 0.50 g/t Au — Cut-off grade assumption from the source statement.

QA notes:

QA INFO: inclusive-of-reserves flag cleared on an inferred row — reserves derive from M&I only, so the flag is meaningless on inferred. QA INFO: document prints mine-plan/LOM-inventory vocabulary ('Mineral Resources within the mine plan') but this row's figures anchor outside those sections — verify the source table; no inventory sourcing is implied. QA WARN: recomputed contained 2507.7582 oz vs reported 2200 oz (13.99% disagreement) Rounding-interval overlap exists at the printed granularity, but a 13.99% gap exceeds the 10% interval-waiver ceiling (t23 STM AuEq-miscopy precedent) — verify the printed contained figure before approval.

Cutoff 0.50 % Cu — Cut-off grade assumption from the source statement.

QA notes:

QA INFO: document prints mine-plan/LOM-inventory vocabulary ('Mineral Resources within the mine plan') but this row's figures anchor outside those sections — verify the source table; no inventory sourcing is implied. QA WARN: cross-category subtotal — this total_resource row on area 'Trek 2' equals the sum of the same area's indicated+inferred leaves — a per-deposit M&I/P&P-style total (t24 LUN/LUG NI 43-101 class). This can be an authoritative issuer-printed per-deposit total or an unhelpful intermediate subtotal. Verify the printed row: retain explicit deposit totals, but reject derived/unprinted or mid-tier rollups before approval. QA INFO: recompute differs 4.62% from the printed contained figure, but the printed tonnes/grade/contained carry ±9.25% rounding granularity (capped per component; the true half-step band of coarse prints is wider) and the remainder sits under the warn threshold — treated as reconciled.

QA INFO: document prints mine-plan/LOM-inventory vocabulary ('Mineral Resources within the mine plan') but this row's figures anchor outside those sections — verify the source table; no inventory sourcing is implied. QA BLOCK: conflicting duplicate — this (project, mining area, commodity, classification, category, as-at date) appears 2 times in the document WITH DIFFERENT figures. At most one copy matches the print; verify each against the document and reject the rest (a copy whose figures appear nowhere in the text is fabricated).
