SnapshotIn 2022, Musselwhite mine is transitioned all line-of-sight load, haul and dump activities underground to fully remote operations with the introduction of automation technology.

Based on a comprehensive review of Newmont’s portfolio of assets following the Newcrest acquisition, the Company’s Board of Directors approved a portfolio optimization program to divest six non-core assets and a development project in February 2024. The non-core assets to be divested include Musselwhite, Éléonore, Cripple Creek & Victor, Akyem, Porcupine, Telfer, and a development project in Canada. In February 2024, the Company concluded that these non-core assets and the development project met the accounting requirements to be presented as Held for Sale in the first quarter of 2024. The sale is probable and will be completed within 12 months.

Deposit type

  • Iron formation hosted

Summary:

The mineralization at Musselwhite can be classified as an Iron Formation hosted gold deposit. Typically, gold in these deposits occurs in cross-cutting quartz veins and veinlets or as fine disseminations associated with pyrite, pyrrhotite, and arsenopyrite hosted in iron formations and adjacent rocks within volcanic or sedimentary sequences (McMillan 1996).

Mineralization is predominantly hosted within meta-chemical sediments (banded iron formations) and in particular within garnet-magnetite-grunerite facies meta-banded iron formations (locally termed the Northern Iron Formation). The location of mineralization is controlled by the intersection of shear zones and folded meta-banded iron formations. These geological controls result in mineralized shoots, which plunge at approximately 15 degrees to grid north, have a down dip extent of up to 150 metres, down plunge continuation in excess of 1.5 kilometres, and across-lithology width of up to 10 metres. Mineralized zones are characterized by abundant pyrrhotite, quartz flooding and, rarely, visible gold.
