Golden Grove

Gossan Hill Portal is a polymetallic underground operation within the Golden Grove mining complex, situated in the Yalgoo Mineral Field, Mid-West Region of Western Australia. The site lies approximately 520 km northeast of Perth, placing it deep within a semi-arid, remote corridor. This geographic isolation creates extended supply chain lead times, elevating the strategic importance of pre-positioned inventory, redundant logistics contracts, and reliable road freight scheduling along the Great Northern Highway.

Golden Grove — including Gossan Hill — operates under 29Metals' active production mandate, classified as an operating asset. Workforce deployment relies on FIFO rotational rosters cycling through Perth Airport, with camp-based accommodation sustaining continuous shift coverage. B2B vendors supplying consumables, reagents, and maintenance services must align delivery schedules to roster changeovers. Camp support services — catering, medical, laundry, and facilities management — represent critical procurement categories requiring long-term service agreements.

Gossan Hill Portal accesses high-grade volcanogenic massive sulphide (VMS) ore bodies via underground development headings. Material handling relies on a network of heavy-duty conveyor systems transferring broken ore from stope faces to surface processing infrastructure. Conveyor belt integrity, idler maintenance, and transfer-point dust suppression are operationally critical. The processing plant handles copper, lead, and zinc concentrates through sequential flotation circuits, demanding precision in reagent dosing and concentrate filtration under continuous production pressure.

29Metals maintains formal commitments to Aboriginal Heritage compliance under the Western Australian Aboriginal Heritage Act, requiring site-specific cultural heritage surveys and ongoing engagement protocols. B2B procurement strategies at Golden Grove prioritise Indigenous supplier participation, with preference for locally-owned Aboriginal enterprises across civil, labour hire, and environmental services. ESG reporting aligns with GRI standards, and vendors entering the supply chain are assessed against sustainability criteria including emissions management, water stewardship, and community benefit contribution.
