Project Case Study: Geosynthetics Supply for FG Gold Process Ponds - Sierra Leone

Client: FG Gold, Sierra Leone
EPCM Contractor: Lycopodium Minerals
Geosynthetics Supplier: Geosynthetics Africa Pty Ltd

---

Project Background

The FG Gold Project, currently under development in Sierra Leone, is a  gold mining project being managed by Lycopodium Minerals as EPCM contractor. As part of its Phase 1 infrastructure, a network of process water ponds was designed requiring robust containment and drainage solutions to meet international environmental and operational standards.

Geosynthetics Africa Pty Ltd was contracted to supply the critical geosynthetic materials based on our specialized expertise and proven track record across African mining projects.

Scope of Supply

Geosynthetics Africa successfully delivered the following key materials:

• GSE HDPE Geomembrane Liner - 1.5mm:
  Supplied and deployed as the primary containment layer for all process water ponds. The high-quality GSE liner ensures chemical resistance, UV stability, and long-term durability, critical for aggressive mining liquids and harsh African environments.

• HDPE Liner Termination Profile Anchor System:
  Delivered for use at all liner-to-concrete interfaces, the HDPE-profile anchors were embedded into concrete walls to create a watertight mechanical bond between the liner and fixed structures.

• Solid HDPE Drainage Pipes with Custom Flanges:
  Designed for high-pressure process flows, these pipes were manufactured to precise dimensions and delivered with custom-fabricated flanges, allowing easy integration with valve chambers and lined pond structures.

• Mirafi   Non-Woven Geotextile :
  Used as a protective cushion layer beneath the HDPE liner to reduce puncture risks and enhance liner performance over irregular subgrade. Our geotextile provides excellent elongation and durability under mechanical stress.
