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.

Cu

Category	Tonnes (Mt)	Grade (% Cu)	Contained (Mt Cu)	As at
Measured	790.00 Mt	0.39%	3.04 Mt Cu	31 Dec 2025
Indicated	2,550.20 Mt	0.43%	10.92 Mt Cu	31 Dec 2025
M&I = Measured + Indicated (overlaps both)	3,340.20 Mt	0.41%	13.96 Mt Cu	31 Dec 2025
Inferred	958.60 Mt	0.42%	4.00 Mt Cu	31 Dec 2025
Total Resources	4,298.80 Mt	0.42%	17.97 Mt Cu	31 Dec 2025
Proved	936.80 Mt	0.45%	4.24 Mt Cu	31 Dec 2025
Probable	758.10 Mt	0.45%	3.38 Mt Cu	31 Dec 2025
Total Reserves	1,694.90 Mt	0.45%	7.62 Mt Cu	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.

QA notes:

QA WARN: bare method label 'Sulphide dump leach' beside tenement/deposit-prefixed method labels on the same project — a multi-block table's lost prefix makes this row read as the project-level method total when it is one block's leaf (t57 MGX ML33760: bare 'Open Pit' was a 4.5x misread).
