McMahon Fimiston TSF
The landscape of gold mining in Kalgoorlie-Boulder has evolved with the construction of a new Tailings Storage Facility (TSF) at KCGM’s Fimiston Gold Mine Operations (Fimiston). Nestled adjacent to the City of Kalgoorlie-Boulder, this expansion project represents a significant stride in gold processing innovation.
Current Disposal Methods: A Shift Towards Sustainability
Presently, the Fimiston Processing Plant manages its tailings through the Fimiston I, Fimiston II, and Kaltails TSFs. However, in a bid to enhance sustainability and capacity, KCGM is steering the construction of a new two-cell TSF adjoining the existing Fimiston II TSF — aptly named the Fimiston II TSF Extension. This expansion is designed to accommodate the growing demands of gold processing and environmental stewardship.
Project Dynamics: Unveiling the Fimiston II TSF Extension
The Fimiston II TSF Extension is not merely an expansion; it’s a strategic investment in the future of gold mining. The two-cell TSF is poised to provide an estimated additional storage capacity of ~94 million tonnes until approximately 2034. This forward-thinking initiative aligns with KCGM’s commitment to responsible mining practises and long-term operational efficiency.
Geotech Australia’s Marching Orders: Precision Testing for Project Success
In March 2023, Geotech Australia proudly joined forces with Macmahon, marking a pivotal role in the Fimiston II TSF Extension. Our commitment to precision testing has been evident through various methodologies employed to ensure project success. Geotech Australia’s role includes:
- Material Compliance Processing: Rigorous testing of bulk samples for Particle Size Distribution, Liquid & Plasticity Limits, Linear Shrink, and California Bearing Ratio.
- Dual Base Facilities: Leveraging both the Bunbury and Kalgoorlie Base Facilities for comprehensive material analysis.
- Onsite Mastery: Our Kalgoorlie team actively supports material and placement practises, offering expertise in compaction control testing using Field Nuclear Density AS1289.5.8.1 and Modified Compaction AS1289.5.2.1.
