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.

QA note (t91a p2): F3(b) CLEARED, no capture gap; but see the grade-basis flag below. Printed Table 11 / Table 1 (Savage River, December 2025): TOTAL Resources "Tonnes (Mt) 464.2 / DTR (%) 44.2 / Fe (%) 68.3". Every printed leaf is already approved and every cross-foot is EXACT: measured 124.6+2.0+33.0+4.8 = 164.4; indicated 64.0+3.8+63.0+2.1+25.4 = 158.3; inferred 36.1+5.2+17.7+0.3+82.2 = 141.5; M+I+Inf = 464.2. The total_resource leaf set sums to 459.4Mt because Table 10 "Stockpile Mineral Resources" prints a single Measured Resources column with no TOTAL column, so the 4.8Mt stockpile books resource/measured only (ac50477d-998a-4c35-b14c-2f61325bf1d8); 459.4 + 4.8 = 464.2 EXACT. Nothing to capture. GRADE-BASIS FLAG (systemic, not a single-row defect - do not fix this row alone): every Savage River table carries the bullet "Elemental compositions were measured from Davis Tube Concentrate", so Fe 68.3% is a CONCENTRATE assay, not an in-situ ore grade, and the doc prints no contained-metal column at all. contained_metal here is a derive (464.2Mt x 68.3% = 317,048,600 t, reported=None) that ignores the printed DTR of 44.2%; the DTR-aware figure is 464.2Mt x 44.2% x 68.3% = 140,135,481 t Fe, i.e. the stored value overstates by 2.26x (= 1/DTR). All 36 GRR rows in the book share this construction, so this needs a class decision (magnetite/DTR reporting basis), not a per-row FIX - escalated in the t91 reply.

Magnetite/DTR basis: this doc states 'Elemental compositions were measured from Davis Tube Concentrate', so the printed Fe% is a concentrate assay and contained_metal (tonnes x Fe%, no printed metal column) overstates in-situ Fe by 1/DTR - ~2.26x at the printed 44.2% resource / 44.7% reserve DTR.

No printed DTR cell of its own: stockpiles print under Proved only, so the class total shares the proved line's DTR (LTR/Paulsens stockpile convention).
