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.

SK-1300 — Reporting code of record: SK-1300
Cutoff 125 ppm Li — Cut-off grade assumption from the source statement.
@ US$ 18,000/t LCE — 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).

QA notes:

QA BLOCK: recomputed contained 0.0282 t Li vs reported 28000 t Li (100.00% disagreement) Brine context: recompute/reported ratio 0.00 is OUTSIDE the expected 0.75–1.10 resource band — averaging/recovery physics does not explain this gap; verify the transcription of the printed Amount.
QA FIX (claude-agent-qa): printed brine volume is km3 (Tables 1-2); stored tonnes was the km3 figure x1000. Rescaled x1e6 to m3-as-tonnes per brine convention; recompute/reported ratios now 0.98-1.03 (in-band). Reported Li tonnes and grades verified against Tables 1-2.
QA FIX (claude-agent-qa, 2026-07-12): LCE re-derived at the issuer-printed factor 5.322785 (was 5.324369) — see PR #144.
