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: tonnes/contained equal the SUM of 3 sibling row(s) of the same classification/category/commodity (Upper Zone, Central Zone, Lower Zone) — 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: recomputed contained 14449895.8393 oz vs reported 18600000.0 oz (22.31% disagreement)
t92 hold: (a2) DISCREPANCY unflagged, raised in review: the grade cell is internally impossible. Stored 86,100,000 t @ 5.22 g/t Ag = 18,600,000 oz, but 86,100,000 x 5.22 recomputes to 14,449,896 oz - a -22.31% self-inconsistency, far outside any print granularity (half-step band [14,427,672, 14,472,136] oz does not reach the stored 18,600,000). Tonnes and contained are BOTH corroborated exactly by the three zone leaves (18,900,000 + 52,500,000 + 14,700,000 = 86,100,000 t EXACT; 1,900,000 + 11,900,000 + 4,800,000 = 18,600,000 oz EXACT), so the defective cell is the grade alone: the leaf-weighted inferred Ag grade is 6.7315 g/t and the grade implied by this row's own printed tonnes and ounces is 6.7192 g/t, i.e. the printed cell should be ~6.72-6.73 g/t. The stored 5.22 is the doc's INDICATED+INFERRED combined Ag grade (912,300,000 + 86,100,000 = 998,400,000 t carrying 148,700,000 + 18,600,000 = 167,300,000 oz -> 5.2150 g/t, prints 5.22) - a cross-row grade-column pickup. F3 cannot see this because tonnes and contained both foot to 0.00%. Not fixed blind: 6.72 vs 6.73 depends on the print, and the same table's inferred Ag NULL is missing entirely from the JV twin TUO (doc 89acd635), so this table region needs one operator re-read. Suggested FIX grade=6.72.

QA WARN: mining_area 'Central Zone' never appears beside project 'Treaty Creek' 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.
