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	—	—	—	—

Total Reserves	36.60 Mt	1.03 g/t	1.20 Moz	26 Jan 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: mining_area 'Makosa' equals the sum of sibling areas (arithmetic subtotal), not a leaf area — approving it alongside the leaf areas double-counts. Reject it (or reject the leaves) before approval.
QA approved: verified against the source print by the tranche-23 agent pass
t92a note-hygiene: the standing 'Makosa equals sum of siblings' WARN is REFUTED — Makosa is a genuine sibling deposit; indicated leaves incl. Makosa reconcile to the 50.6 Mt project print (t92 a6)
