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 BLOCK: recomputed contained 1350.3314 oz vs reported 1000 oz (35.03% disagreement) Rounding-interval overlap exists at the printed granularity, but a 35.03% gap exceeds the 10% interval-waiver ceiling (t23 STM AuEq-miscopy precedent) — verify the printed contained figure before approval. QA WARN: mining_area 'Central Main' never appears beside project 'Spring Hill' in the document text (nor as a sub-row label) — an invented area label re-presents a whole-project row as a phantom leaf (live t52: Brucejack 'Underground' silver reserves; the print has no such split). Verify the printed row label; if the figures match an approved area-less row, reject this copy as a duplicate.
