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 13.42 g/t Au — Cut-off grade assumption from the source statement.
@ US$ 2,500/oz — 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).

The indicated ounces cell is wrong in the print and two other printed rows prove it: (a) measured 171 + indicated 1,104 = 1,275koz but the printed M&I cell is 1,185koz, and that M&I cell is self-consistent (61,797kt @ 0.60 = 1,192koz), giving indicated = 1,185-171 = 1,014koz; (b) the printed "Total Gold" indicated row (101,683kt, 0.65 g/t, 2,131koz) equals Palmarejo 792 + Las Chispas 61 + Rochester 100 + Kensington 164 + Wharf 1,014 EXACTLY, and fails by 90koz if Wharf is 1,104. The row's own cells agree: 52,116kt @ 0.61 = 1,022koz. Reads as a 1,014 -> 1,104 transposition in the Wharf cell. Row stands as printed; operator FIX candidate contained_metal=1,014,000 (and reported), worth ~90,000 oz Au.
