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.

Cutoff 0.20 % Mo — Cut-off grade assumption from the source statement.

QA notes:
QA WARN: tonnes/contained equal the SUM of 2 sibling row(s) of the same classification/category/commodity (Open Pit, Underground) — likely a printed multi-deposit rollup/subtotal. Policy keeps leaf rows and printed whole-project Totals only; reject mid-level rollups (double-count).

QA notes:
QA WARN: tonnes/contained equal the SUM of 2 sibling row(s) of the same classification/category/commodity (Open Pit Combined, Underground Concentrator) — likely a printed multi-deposit rollup/subtotal. Policy keeps leaf rows and printed whole-project Totals only; reject mid-level rollups (double-count).
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.
