Evidence (2)

Two or more independent sources state this.

SourceOwnership passes through AMNT (formerly PT Newmont Nusa Tenggara), which the company states operates Batu Hijau; Newmont's independent completion release establishes the 2016 transfer. No share qualifier: the 82.2% quoted in 2016 was the interest acquired in the SUBSIDIARY, not a stake in the mine, and the current holding was not sourced.Origingold-hubObserved2026-09Asserted2026-09-11

Evidence

One source states this, and it is labelled as one source.

SourceSwiss Precious Metals Transparency Platform supplier map. Appearance establishes that the company is named in a refiner published sourcing list for the stated year, NOT a sourcing edge — the platform own FAQ states that the parties it lists as suppliers are in fact its customers, which is precisely why no SOURCES_FROM edge is drawn from this dataset.Origingold-hubObserved2026-09Asserted2026-09-11
