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.

Sub-category rows are as disclosed (no Reserves-treatment netting); the Total rows honour the Resources treatment and Inferred-policy toggles, so components may not sum to the Total.

Dotted tonnes/grade are derived under the active Resources treatment: tonnes are netted of (or grossed by) the reserve tonnage alongside contained, and grade is re-derived as netted contained ÷ netted tonnes — not the published figures.

QA notes:

QA INFO: inclusive-of-reserves flag cleared on an inferred row — reserves derive from M&I only, so the flag is meaningless on inferred. 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 WARN: mining_area 'Total' looks like a table SUBTOTAL line, not a leaf area — approving it alongside the leaf areas double-counts. Reject it (or reject the leaves) before approval. QA INFO: identical figures to area(s) 'Open-Pit' — likely the same printed line under two labels (a summary and a detail table); keep one label and reject the other.
QA fix: Print-exact against the "Total" block of the Mineral Resources Statement as of November 30, 2025 (Inferred 2,033 kt / 1.17 g/t Au / 77 koz), but stored under the literal subtotal label "Total". Clear to null so the whole-project Inferred total dedupes against the Open-Pit leaf under the same null-wins convention the AUTO AREA-FIX applied to the Ind
