Telfer Mine

Telfer Main Dome is situated in the Great Sandy Desert, approximately 1,300 km northeast of Perth within the Pilbara region of Western Australia. The site operates under extreme arid conditions, with surface temperatures routinely exceeding 50°C in summer months. This thermal environment imposes critical constraints on heavy machinery — requiring mandatory heat management protocols, including enhanced cooling systems, hydraulic fluid monitoring, and scheduled thermal shutdowns to prevent catastrophic equipment failure across the fleet.

Telfer operates as a 24/7 continuous production asset, combining open-pit and underground extraction across the Main Dome and West Dome ore bodies. The site's energy matrix is heavily dependent on diesel combustion at industrial scale, powering haul trucks, processing plant substations, and auxiliary infrastructure. Greatland Gold completed its 100% acquisition from Newmont Corporation on 4 December 2024, repositioning Telfer as a cornerstone asset within a junior-to-mid-tier growth strategy targeting sustained gold and copper output.

• Commodities: Gold (primary), Copper (co-product), Lead, Zinc (by-products)
• Mining method: Open pit + underground (sub-level caving)
• Processing: On-site CIL/flotation circuit
• Workforce model: FIFO rotating roster via dedicated Telfer Airport (TEF)

The Telfer processing facility integrates a multi-stage conveyor network handling high-tonnage ore movement from pit and portal to the primary crusher and mill feed. These conveyor systems operate under extreme dust and heat loads, demanding reinforced belt specifications, thermal-resistant idlers, and automated tensioning systems. Power supply to the processing plant and underground operations is delivered through dedicated high-voltage substation infrastructure, with diesel generation sets providing baseload and redundancy capacity critical to uninterrupted metallurgical throughput.

• Primary crusher feed via overland and in-pit conveyor systems
• SAG/Ball mill grinding circuit with CIL gold recovery
• Copper-gold flotation concentrate production
• Underground paste fill and ventilation infrastructure

Telfer's remote desert footprint presents a material decarbonisation challenge under Greatland Gold's emerging ESG framework. The site's legacy diesel dependency is a primary Scope 1 emissions driver. Industry benchmarks for analogous Pilbara operations indicate pathways via solar-diesel hybrid microgrids and progressive electrification of light vehicle fleets. Greatland Gold, as a newly independent operator post-Newmont divestiture, is expected to define its ESG roadmap — including renewable energy integration targets and water stewardship commitments — aligned with ASX and AIM investor disclosure expectations.

• Scope 1 reduction pathway: solar hybrid microgrid integration
• Fleet electrification: light vehicles as initial EV transition vector
• Water management: closed-loop processing circuits in arid environment
• Reporting framework: ASX Listing Rules + AIM ESG disclosure obligations
