Imerys, EMILI Phase IV, France

EMILI Phase IV is a three-year diamond drilling campaign targeting a resource upgrade ahead of the mine’s pre-production phase, scheduled for 2028. The program comprises:

• • Surface drilling in 2025–2026, followed by
• • Underground drilling in 2027

In total, approximately 12,000 meters of inclined and vertical core drilling will be completed to refine geological models, confirm resource continuity, and enhance resource classification—all critical to underpinning the feasibility and design of the future mine and processing facilities.

Project Challenge

This ambitious campaign requires seamless coordination across varied drilling environments and timelines.

• High-quality coring and data collection to support resource estimation and upgrade
• Compliance with stringent environmental and sustainability standards to align with Imerys’s responsible mining commitments

• Preparation for the pre-production phase, with an expected commercial ramp-up by 2028
• Transition from surface to underground operations with logistical precision
