Endeavour – Ity Gold Mine (TSF 2 Stage 3)
2026
Endeavour – Ity Gold Mine (TSF 2 Stage 3)
We are executing the geomembrane installation for Stage 3 of the TSF 2 waste storage facility for Endeavour Mining at the Ity Gold Mine in Côte d'Ivoire, West Africa. As part of the expansion of the existing storage cells, continuous containment of the HDPE liner system is treated as the primary design criterion; panel deployment and welding quality control are conducted alongside field testing. Works, which started in May 2026, are ongoing...

Endeavour – Lafigue Gold Mine (TSF 3)
We undertook the geomembrane deployment for the TSF 3 project we are executing for Endeavour Mining at the Lafigue Gold Mine in Côte d'Ivoire, West Africa. In the third phase of the waste storage facility, the geosynthetic application for the long-term performance of the base and slope liner system is managed in conjunction with the deployment plan and field controls. Works, which started in March 2026, are ongoing.

Allied Gold – Kurmuk Gold Mine (TSF 1)
We undertook the geomembrane and geotextile deployment and piping works for the TSF 1 (Waste Storage Facility) project we are executing for Allied Gold at the Kurmuk Gold Mine in Ethiopia, East Africa. The containment integrity of the base liner system is ensured through the welding, deployment, and testing discipline of geosynthetic materials in compliance with field conditions. Piping lines are integrated according to the drainage and conveyance requirements of the facility...

Tümad – Lapseki Gold Mine
The waste storage pond in Lapseki is positioned as a critical structure connected to the heap leach system in terms of solution management. Wind load and surface evaporation in regions close to the coast of Çanakkale create a design framework where the containment system requires long-term stability not only at the base, but also in the slope and upper slope regions. The pond liner system therefore requires anchoring...

Tümad – İvrindi Gold Mine
The Balıkesir İvrindi site constitutes an important link in Tümad Mining's heap leach operations in Western Anatolia. The variable topography of the region and the need for gradual expansion of the existing pad area made it mandatory to seamlessly connect the new lining phase to the existing containment system. Geomembrane installations carried out within this scope; extrusion of the new sheets with the existing HDPE liner at the pad expansion boundaries...

Endeavour – Ity Gold Mine (TSF 2 Stage 3)
The opening of a second waste storage basin meant a critical threshold in the site's long-term mining plan. Since the new TSF required a water balance and containment concept independent of the existing facility, the panel layout, weld line density, and drainage corridors were configured from scratch. The use of textured HDPE geomembrane in the base and slope regions, friction parameters...

Centerra Gold / Öksüt – Öksüt Gold Mine
The Öksüt site in Kayseri Develi has become one of Turkey's most active heap leach facilities since the day it was commissioned. The gradual movement of the site topography and the expectation of long-term leaching performance meant that the liner system required not only containment, but also chemical and mechanical resistance for years. Textured in the geomembrane installations carried out within this scope...

Alacer Gold / Anagold – Çöpler Gold Mine TSF
The permanent contractor presence during the operational phase of the waste storage facility represents a living engineering process rather than a static construction project. As the dam body progresses during raising stages, the growth of the liner system as well requires special welding details and testing procedures at the connection lines between the existing HDPE geomembrane boundaries and the newly deployed panels. With the geotextile-GCL-geomembrane-geocomposite sequence at the base…

Alacer Gold / Anagold – Çöpler Gold Mine HLF
The on-site presence, which has continued uninterrupted for over a decade, constitutes a rare reference in the sector regarding how a liner system that grows with the operational process in a heap leach facility is managed. Every expansion made in the advancing units of the leach pad is connected to the boundaries of previously deployed panels with additional seam welds; the extrusion used in these connection details...

Eldorado Gold / Tüprag – Efemçukuru Gold Mine
Due to its underground mining-based structure and flotation concentrate production, Efemçukuru demands a different engineering approach compared to conventional open-pit mines in waste storage facility design. In basins where fine-grained and high-moisture-content tailings are stored, the long-term containment performance of the base liner system is formed compositely by the bentonite-based GCL and HDPE geomembrane together...
