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.
† Tonnes and grade as published (not net): the reserve statement prints no tonnage to net out, so only Contained honours the Resources treatment on this row.

Same swap, and this is the printed project-level line: p.14 "Total Proven 1-7 34.9 30.8 884.0 101.2". It is figure-identical to the West leaf ONLY because the other well field prints all dashes ("Santa Barbara - - - - -"), so Proven has a single contributing leaf. Both are printed cells and both stand — the DUPLICATE-AREA warn on this pair is a false positive on exactly the t96 all-dashes precedent, not a summary duplicating its leaf. Same re-basis and recovery reasoning as 7a8f3d37.
Rows are hierarchical, not additive — do not sum a column across rows. Whole-project rows (Area “Total”) already contain the indented named-area rows beneath them, and an issuer's printed per-deposit total can itself contain other listed areas. All derived totals and rollups on this site already exclude the overlapping rows.
† Total-row tonnes/grade as published (not net): the reserve statement prints no tonnage to net out, so only the contained figure honours the Resources treatment there.

Printed "LCE 705.2" kt is recovery-adjusted and reproduces exactly as 214.9 x 0.6165 x 5.3228 = 705.2, which is the cleanest single proof in the document that its LCE column embeds the 61.65% factor; carried as recovery_pct.

Stored tonnes_t=30,800,000 is the Li Metal cell (30.8 kt) read as Mt; stored contained_metal_reported=34,900 is the Pumped Brine Vol cell (34.9 Mm3) read as tonnes; contained_metal was then derived off a VOLUME (34,900 x 5.322785 = 185,765). Correct assignment: tonnes_t = 34.9 Mm3 = 34,900,000 m3 of brine, which recomputes against the printed grade as 34,900,000 x 884.0 mg/L = 30,852t Li vs the printed Li Metal 30,800t (0.17%) — the swap is what produced the 21.99% block. contained_metal_reported = printed Li Metal 30.8kt = 30,800t; contained_metal = 30,800 x 5.322785 = 163,941.778t LCE. Deliberately NOT the printed "LCE 101.2" kt: note 3 says "A combined process recovery factor of 61.65% was applied" and note 5 says "LCE = 5.3228 multiplied by the mass of lithium metal", and 30.8 x 0.6165 x 5.3228 = 101.07 ~ 101.2 — so the deck's LCE column is recovery-adjusted PRODUCT, not contained metal (the t95c/t96 DTR-product class). Recovery carried in recovery_pct instead. DUPLICATE-AREA warn adjudicated as a false positive — see 157af72f.
