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).

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.

Ref: Gold Resources at December 31, 2025

SK-1300 — Reporting code of record: SK-1300
@ A$ 2,300/oz — Metal price assumption used to derive this estimate.
excl — Stated Resources are EXCLUSIVE of Reserves — they sit on top of the reserve, so decks quoting inclusive resources will show a larger figure (inclusive = this row + the converted reserve).
attrib — Figures are net to the issuer's ownership interest as reported (attributable basis) — NOT 100% of the project.

QA notes:

QA WARN: identical figures appear under ANOTHER area label of this project in the same document — likely one printed estimate stored twice (a summary/grouping line duplicating its leaf). Keep one copy; reject the relabelled twin. QA BLOCK: recomputed contained 1053901.4725 oz vs reported 1300000 oz (18.93% disagreement) Rounding-interval overlap exists at the printed granularity, but a 18.93% gap exceeds the 10% interval-waiver ceiling (t23 STM AuEq-miscopy precedent) — verify the printed contained figure before approval.
