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).

Changes — Zn

Every project whose two most recent statement vintages differ, per commodity and classification — the append-only history as a feed of upgrades, downgrades and depletion. Each row names the exact pair of as-at dates it compares; the delta is in the commodity's own contained unit and as a unit-free %.

Like compared with like: both vintages are the issuer's printed totals, each normalised onto the active Basis and Reserves treatment using its own statement's inclusive/exclusive flag — a delta is never a printed figure against a re-derived one, nor an inclusive-stated figure against a netted one. The cost of that honesty: projects that disclose only sub-category rows (no printed total) don't appear here, and figures can differ from the screener, which re-derives totals under the Inferred policy. Same-date restatements collapse to the latest approved extraction; a first-ever disclosure is news, not a change — see the Dashboard's Recent updates feed.
