Case Study:

Kurmuk Gold Mine – Ethiopia

Role: Early Works & Structural Assembly Surveying

Client: Mining Contractor

Location: Kurmuk, Ethiopia

Project Overview

The Kurmuk Gold Project is a major gold mining development in Ethiopia, designed to unlock one of the region’s most promising deposits. The site includes extensive processing infrastructure, material handling systems, and supporting civil works. Geovantage was appointed to join the early works team, providing critical surveying services to establish the project’s geodetic control, set out foundations, and guide the precision assembly of large steel structures. In a mining project of this scale, accurate early-stage surveying directly impacts plant performance. Every conveyor, crusher, and processing facility must be aligned to exact tolerances to ensure operational efficiency once production begins.

Challenges Faced

Ensuring seamless integration between civil and mechanical construction teams.
Maintaining millimetre-level tolerances over large structural footprints.
Coordinating survey efforts across multiple work fronts in a busy early-works schedule.
Remote location with limited existing survey control and logistical constraints.

Scope of Work

Volume and progress measurement for earthworks.
Alignment checks during steel erection.
As-built surveys for all early works.
Foundation and bolt set-out for structural steel.
Geodetic control setup and verification.

Our Approach

GeoVantage deployed a dedicated field team equipped with advanced surveying technology to deliver end-to-end survey support for the gold processing facility’s early stages:

Progress Monitoring: Carried out regular as-built and progress surveys to support reporting and contractor claims.
Structural Alignment Support: Provided live survey data during assembly to ensure perfect alignment of large steel modules.
Quality Assurance Checks: Verified each foundation and bolt cluster prior to steel erection.
Foundation & Anchor Bolt Layout: Precisely set out concrete foundations and bolt patterns for processing plant steelwork.
Control Network Establishment: Created a robust primary and secondary control network spanning the site, tying all works to a unified reference frame.

Outcome & Impact

Geovantage’s involvement at Kurmuk Gold ensured that every structural and civil element was built on a foundation of precision. This accuracy in the early works phase not only reduced the risk of rework but also ensured the seamless integration of mechanical equipment during plant commissioning.

The project highlights Geovantage’s capability to operate in remote, logistically challenging mining environments while delivering the same high-level accuracy and quality expected on world-class mining projects across Africa.
