Fundamental to geotechnical engineering is the understanding of the complex engineering properties of rock and soil and developing mine designs that maximise the financial return with careful consideration of the risks associated with achieving these designs. Xstract's geotechnical engineers are specialists in assessing the structure of rock and soil and then applying leading edge geotechnical engineering practice giving an optimised solution.

Xstract's team of geotechnical engineering consultants and associates have capabilities in open cut and underground coal, precious metals, base metals and mineral sands mining. We have worldwide experience with conceptual, prefeasibility and feasibility studies, short and long term mine design input and strategic planning. Xstract’s geotechnical engineering team undertakes studies as part of a much larger Xstract study team or work alongside other consultants and in-house specialists to deliver these studies. We have worked with projects ranging from very small operations through to multinational operations across numerous countries and commodities.
