Mineral Assessments

Tetra Tech delivers integrated mineral assessment services to inform development decisions and support geotechnical, environmental, and planning requirements. Our geoscience and geotechnical specialists work closely with clients to identify and evaluate mineral resources across a wide range of sites and geological settings.

From early-stage feasibility through to permitting and post-closure, our approach combines advanced surveying and testing techniques with expert data analysis to characterise ground conditions and quantify mineral potential. We help unlock resource value, reduce risk, and ensure regulatory compliance.
