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).

Manual entry

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.

Ag

Category	Tonnes (Mt)	Grade (g/t Ag)	Contained (Moz Ag)	As at
Measured	96.00 Mt	41.00 g/t	126.55 Moz	31 Dec 2025
Indicated	29.60 Mt	49.00 g/t	46.63 Moz	31 Dec 2025

Inferred	2.00 Mt	72.00 g/t	4.63 Moz	31 Dec 2025
Total Resources	127.60 Mt †	43.34 g/t †	0.00 Moz	31 Dec 2025
Proved	61.00 Mt	44.00 g/t	86.29 Moz	31 Dec 2025

Total Reserves	71.00 Mt	42.00 g/t	95.87 Moz	31 Dec 2025

M&I is the issuer's printed Measured + Indicated subtotal — it overlaps the Measured and Indicated rows and is never added alongside them; the Total rows and every rollup already exclude it.

† Tonnes and grade as published (not net): the reserve statement prints no tonnage to net out, so only Contained honours the Resources treatment on this row.
