Macmahon’s two-year Daisy Milano extension: planning notes for mine engineers - Geomechanics.io

AI desk brief

Macmahon Underground secured a two-year extension from Vault Minerals to keep providing underground mining services at the Daisy Milano gold mine in Western Australia’s Kalgoorlie region. The deal covers ongoing mine development and production, implying stable scheduling, unchanged ground support regimes and continuity of existing underground fleet and workforce arrangements through the extension period.

From a supply perspective, the contract reduces near-term operational disruption risk at Daisy Milano rather than signalling any step-change in output. The note also highlights Macmahon’s broader build-out of underground capability across gold and battery metals in the Kalgoorlie labour market.
