Agnew Gold Mine

Agnew Gold Mine is situated in the Lawlers district of the Goldfields-Esperance region, Western Australia — 23 km west of Leinster and 375 km north of Kalgoorlie. The site occupies semi-arid terrain characterised by extreme thermal cycling, minimal annual rainfall, and no perennial surface water. Water supply infrastructure — including managed bore fields and on-site storage — is operationally critical. All potable and process water must be sourced, treated, and distributed under strict allocation protocols, making water management a primary procurement and engineering priority for B2B service providers.

Operated by Gold Fields Ltd. through its wholly owned subsidiary Agnew Gold Mining Company Proprietary Limited, the mine is an actively producing asset that delivered 45 koz of gold in Q1 2026. The operation runs continuous underground extraction across multiple active stopes. Diesel fuel supply and on-site power generation infrastructure underpin 24/7 operational continuity. Key B2B procurement categories include:

• Bulk diesel supply and fuel management services
• On-site dual-fuel or hybrid power generation maintenance
• CIL reagent supply (cyanide, lime, activated carbon)
• Underground mining contracting and ground support services
• Explosives supply and shot-firing services

Agnew operates multiple underground mining fronts, with Waroonga and New Holland in active production and Redeemer under development. The orebody geology — narrow, high-grade gold-bearing lodes — demands precision extraction methods. Infrastructure and equipment procurement priorities include:

• Low-profile LHD loaders and narrow-vein jumbo drill rigs
• Raise boring and development heading services
• Portal construction and ground rehabilitation engineering
• CIL processing circuit consumables and maintenance
• Ventilation, dewatering, and paste fill systems

Surface open-pit operations at Barren Lands concluded in 2023; all current extraction is subterranean.

Gold Fields maintains formal Aboriginal Heritage compliance obligations under Western Australian heritage legislation, requiring heritage surveys and cultural monitors for all ground-disturbing works. B2B suppliers operating on-site are expected to align with Gold Fields' supplier diversity framework, which prioritises engagement with Aboriginal-owned enterprises and local Goldfields businesses. ESG procurement priorities include:

• Heritage survey and cultural heritage monitoring services
• Indigenous workforce training and employment programs
• Renewable energy integration and emissions reduction services
• Environmental monitoring (water, dust, tailings) and reporting
