Lihir Ground Stabilisation Project

Type of project: Mining Infrastructure (Retaining Wall)

Client: Newmont
Location: Lihir Island, Papua New Guinea
Completed in: 2025

Delivered for Newmont Corporation, the Lihir Ground Stabilisation Project was a first-of-a-kind, and highly technical project undertaken in partnership with Spiecapag’s sister company, Menard Oceania. It consisted in securing a benched retaining wall with cabled strength anchors in a geothermally active environment to enable mining operations to continue in the area.

Three benches were stabilised over the course of 46 months, with an impressive 1,315 ground anchors and 4,425 metres of waler beam. Even more remarkable: the project had no time lost to injuries with approximately 2.3 million hours worked, a testament to the team’s unwavering commitment to safety & excellence.
