The on-site presence continuing uninterrupted for over a decade constitutes a rare reference in the sector regarding how a lining system growing alongside the operational process in a heap leach facility is managed. Every expansion carried out in the advancing units of the leach pad is connected to the boundaries of the previously deployed panels with additional seam welds; the extrusion welding techniques and double-track seam reliability used in these connection details form the basis of the facility's long-term containment performance.

The geonet drainage layer placed on the composite liner consisting of GCL and textured HDPE geomembrane at the pad base provides high hydraulic conductivity in directing the pregnant leach solution to the collection lines. While the corrugated HDPE pipe network forms the backbone of the solution distribution and collection system, the joint details at line intersections are joined via electrofusion, making them resistant to deformation under pad load.

Erzincan's continental climate necessitated reflecting winter freeze-thaw cycles and high summer UV exposure into the material selection. Applications carried out over the years under different seasonal and different phase conditions, together with the continuity of quality control documentation, provide a consistent traceability record for the employer.
