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.

Table 2 prints exactly two Measured lines — Jugan Opencut 3,790,000 t @ 1.66 = 203,000 oz and Jugan Underground 11,743 t @ 2.75 = 1,037 oz — summing 3,801,743 t / 204,037 oz (-1.68% t / -2.37% oz). No third Measured line exists to capture. Besra's Table 2 does not foot internally: its five printed deposit sub-totals (Jugan Opencut 8,630,000 t/414,000 oz; Jugan Underground 3,986,956 t/263,383 oz; Bekajang 8,546,400 t/399,400 oz; Sirenggok 8,626,000 t/275,400 oz; Pejiru 22,375,800 t/889,300 oz) sum 52,165,156 t / 2,241,483 oz against a printed Bau Total of 53,010,300 t / 2,285,000 oz — an 845,144 t / 43,517 oz publisher-side residual (Table 2 note: 'Resource numbers may not total exactly due to rounding'). That residual decomposes across categories as Measured 64,857 t/4,963 oz + Indicated 702,922 t/35,381 oz + Inferred 77,366 t/3,172 oz = 845,145 t / 43,516 oz, i.e. the SAME gap seen two independent ways. The four Bau Total category rows themselves cross-foot exactly (3,866,600 + 8,694,800 + 40,448,900 = 53,010,300 t; 209,000 + 467,000 + 1,609,000 = 2,285,000 oz), so the rollup set is coherent.

That residual decomposes across categories as Measured 64,857 t/4,963 oz + Indicated 702,922 t/35,381 oz + Inferred 77,366 t/3,172 oz = 845,145 t / 43,516 oz, i.e. the SAME gap seen two independent ways.
