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.

The row itself still stands print-faithful under the printed-canonical rule — the issuer prints 11.0 Moz twice (also in the CEO quote, "With an existing 11.0 million ounce Inferred Resource") and no cell may be recomputed away.

QA notes:

QA INFO: recompute differs 3.19% from the printed contained figure, but the printed tonnes/grade/contained carry ±4.90% 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.
