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.

QA notes:

QA WARN: document contains mine-plan/LOM-inventory table vocabulary ('diluted Resource') — such tables print production-target inventory, NOT a Mineral Resource estimate, and their rows look clean at store time (t23 TGM class). Map each row to its source table before approval and reject rows sourced from the mine-plan/inventory table. QA WARN: tonnes/contained equal the SUM of 2 sibling row(s) of the same classification/category/commodity (Coomber, Rylstone) — likely a printed multi-deposit rollup/subtotal. Policy keeps leaf rows and printed whole-project Totals only; reject mid-level rollups (double-count). QA BLOCK: conflicting duplicate — this (project, mining area, commodity, classification, category, as-at date) appears 2 times in the document WITH DIFFERENT figures. At most one copy matches the print; verify each against the document and reject the rest (a copy whose figures appear nowhere in the text is fabricated). QA INFO: possible missing commodity coverage — the document prints Cu, Fe grade/contained column(s) but the extraction emitted no Cu, Fe rows; verify the R&R table columns (live class: GMTL Pilot Mountain Zn).
