Karowe Mine

PROGRESS
We are progressing well with the contract and will complete it in the next few months. It has been an incredible journey from an international expat team that includes no less than 9 different nationalities. The $36 million project funded by Millennium Challenge Account (MCA) includes 2 bridges, a concrete spillway, pump house, earth dam and a new surfaced road. We are in talks with MCA for further work in the Nacala area, a true testament to the quality of work our WBHO team has produced.

This Northern Mozambican project has had more than its fair share of challenges but the team has taken them in their stride, growing in confidence after every success.
