Geotest Projects Eldorado Gold, Olympias Delineation, Greece

Project Information

Olympias gold-lead-zinc underground mine has a reported reserves of 2 Moz gold. All drilling works were conducted inside the Olympias mine and aimed to verify old historic drilling findings and provide enough core material to increase the geological confidence with modern assays.

Client :Eldorado Gold
Location :Greece
Year launched :2016
Status :Finished
Value :4.0 M €
Drilled :>45,000 meters

Project Description

The delineation program targeted a drilling grid spacing between 15 and 30m. Three (3) underground rig are deployed to execute both downward and upward boreholes with a maximum length of approximately 160m. Maintaining high-productivity and deliver on time was crucial for the initiation of the production in Olympias mine.

Project Challenge

Hard constraints for this project was set due to the planned initiation of the production phase in the newly re-opened Olympias mine.

Upward and downward boreholes of up to 160m
High recovery to facilitate geological conclusions
Push to deliver on time to facilitate production initiation

RESULTS

Several drilled areas resulted in verification of old findings, underground stope design and a robust LoM plan. We successfully drilled and delivered several hundreds of boreholes to the planning team of the Client.
