Reserve update adds seven hundred twelve thousand ounces of gold alongside twenty‑three thousand tonnes of copper
Two‑year operational plan aligns Telfer activity with Havieron underground integration
Feasibility study explores higher mining rates leveraging existing milling and conveyance assets
The mining sector remains a cornerstone of resource supply chains, with companies seeking to expand reserves and refine operational models. Greatland Gold PLC (LSE:GGP) has released new figures for its Telfer gold‑copper mine in Western Australia, underscoring its role in global mineral production.
Updated Reserve and Resource Figures
Greatland Gold PLC (LSE:GGP) reported a reserve increase at Telfer to seven hundred twelve thousand ounces of gold accompanied by twenty‑three thousand tonnes of copper. This update complements an earlier resource statement of three million two hundred thousand ounces, bringing the combined gold endowment, inclusive of Havieron, to in excess of ten million ounces. The rapid finalisation of these estimates, achieved within months of acquisition, reflects focused evaluation work and integration of recent drilling results.
Operational Continuity Planning
A strategic timeline spanning two years outlines efforts to sustain dual‑train processing at the Telfer operation. Infrastructure upgrades and stockpile management are designed to ensure uninterrupted throughput as production transitions. Existing open pit stages and underground circuits will feed into parallel milling trains, maintaining plant utilisation rates and supporting steady material flow during the transition to Havieron output.
Havieron Integration Efficiency
Havieron’s inclusion into Greatland Gold’s portfolio brings an ore body with grades significantly above those of the open pit, reinforcing output and lowering unit costs on the global cost curve. The synergy between Telfer’s established infrastructure and Havieron underground workings offers advantages in logistics and processing configuration. Underground haulage routes and shared water‑handling systems are being finalised to optimise cycle times and reduce operating overheads.
Feasibility Study for Increased Mining Rates
An in‑depth feasibility review is under way to assess higher mining rates at Havieron, targeting an uplift that would capitalise on underused mill capacity. The study examines ore handling, conveyance circuit expansions and additional fabrication of plant modules. Early engineering designs explore the installation of new crushing units and refurbishment of mill feed systems, positioning the operation for a scalable increase in throughput.
Seismic Surveys and Technical Collaboration
Complementary to drilling programmes, three‑dimensional seismic campaigns at Coyote Wash and Sagebrush sites have refined structural models for fault interpretation and reservoir characterisation. Collaboration with specialist consultants has yielded high‑resolution imaging that guides well placement and completion design. These technical partnerships underpin strategic decision‑making, aligning subsurface knowledge with surface infrastructure planning.
