Global mining consultancy providing independent technical and strategic services across the entire mine lifecycle

/ Who We Are

Our number one goal is to unlock the true value of your mining project

Orelogy is a technical mining consultancy, with global multi-commodity expertise across both Open Pit and Underground mining. Our capabilities span the project life cycle – from Studies and Project Management to Operational Readiness, Support and Governance.

Established in 2005, we have evolved from a small specialist consultancy into a trusted partner for mining companies globally. In February 2022, Orelogy was acquired by the Perenti Group, an ASX-listed, diversified mining services organisation that includes contract mining, drilling services, mining services, and technology solutions.

Today, our team unites extensive technical expertise both above and below ground that focuses on practical, value accretive outcomes that extend beyond the mine face. As we look to the future, Orelogy continues to expand and evolve within the broader Perenti ecosystem.
