Mining-Technology / International MiningAssessment
The 2023 JORC statement (effective 31 Dec 2023) reports 1,595.2 Mt of proved and probable reserves at 0.51% Cu (8.2 Mt contained copper) at this porphyry Cu-Mo operation, with a further 1,186 Mt of inferred resource at 0.41% Cu. Public resource reporting characterises grade, tonnage and reserve life; it is not designed to resolve element deportment by mineral phase, nor where molybdenum and silver byproducts and any refractory-hosted value report across concentrate, tailings and residue at a first-decade operation of this scale. Whether recoverable value resists conventional flotation is a testable question that a DETECT characterisation is built to answer. Element deportment by mineral phase is not resolved in the public reporting located, and the figures here are machine-extracted from the cited filings and not yet independently verified.
Screening signals
Each item below is something a cited source states. Nothing here asserts that unrecovered material is present.
Molybdenum, silver is named as a byproduct or co-product commodity, and the resource statement located carries no grade or contained-metal figure for it.
Molybdenum, silver
Mining-Technology (porphyry Cu-Mo)The deposit is described as Porphyry copper-molybdenum. Porphyry systems are documented as commonly carrying molybdenum, gold, silver, rhenium and tellurium as byproduct or unrecovered constituents.
Porphyry copper-molybdenum
Mining-TechnologyOpen technical questions
Public resource reporting characterises grade and tonnage to a code standard. It is not designed to resolve element deportment by mineral phase. These are the questions this operation’s public reporting was not built to answer.
The resource statement reports contained Copper but no deportment for the molybdenum, silver carried in the concentrate; in which mineral phase that value resides is not resolved by the assays disclosed.
Grounded in: Molybdenum, silver is named as a byproduct or co-product commodity, with no separate grade in the located resource statement. source
The deposit is described as Porphyry copper-molybdenum; public code-compliant reporting characterises grade and tonnage to a code standard but is not designed to resolve element deportment by mineral phase in this material.
Grounded in: The deposit type is reported as Porphyry copper-molybdenum. source
How those questions get answered
These are testable questions about element deportment by mineral phase, which code-compliant public reporting is not designed to resolve. A DETECT™ characterisation of a representative physical sample is the instrument built to answer them: it measures which phases host the value and how much is locked. It does not assume a result.
What was sought and not found
- Reserve/resource effective date is 31 Dec 2023 — refresh from Anglo American ORMR 2024 when quoting.
- Molybdenum and silver grades not in the ORMR summary tables; pull from the operation's own reporting if needed.
- Copper recovery % not publicly stated in the summary; a gap, not a hidden number.
- Figures machine-extracted, not hand-verified.
- Figures are machine-extracted from the cited filings and not yet independently verified by a qualified person (verification_status = machine_extracted_unreviewed). Confirm against the cited filing before external use.
