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.

Cutoff 0.30 g/t Au — Cut-off grade assumption from the source statement.

QA notes:

QA WARN: unrecognised source metal label 'g/tAu' for Au — verify the commodity mapping. QA INFO: recompute differs 1.13% from the printed contained figure, but the printed tonnes/grade/contained are only good to ±6.05% (rounding granularity) — treated as reconciled. QA WARN: mining_area 'Open Pit & UG' never appears beside project 'Mt Gibson Gold Project' 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.
QA fix: p.18 L413 MGGP Inferred 38.1 Mt @ 0.8 = 969 koz = 38,100,000 t / 0.8 / 969,000 oz, print-exact; 'Open Pit & UG' is the printed Type column on a single-line operation — rule 4(c). 'g/tAu' warn dismissed.
