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.

QA notes:

QA INFO: identical figures to area(s) 'Combined Zn Resources' — likely the same printed line under two labels (a summary and a detail table); keep one label and reject the other.
t88 swarm r2 (a1): Stale guard note — do NOT act on it: this row (measured Ag 70,000 t @ 53.0 g/t = 119,279 oz) is not figure-identical to any approved 'Combined Zn Resources' row, which is a total_resource ROLLUP of 1,750,000 t (the Cu-dominant deposit rows sum 9,240,000 t / 112,539 t Cu vs printed 9,240,000 t / 112,000 t Cu; the Zn-dominant rows sum 1,720,000 t / 116,659 t Zn vs printed 1,750,000 t / 118,000 t Zn). The attached QA INFO 'keep one label and reject the other' premise no longer holds against the approved set. No status change.
