Project Summary:

The characterisation of subsurface properties with high spatial resolution using non-invasive methods is one of the “holy-grails” of mineral exploration. While currently used seismic methods provide the highest resolution among the remote sensing methods, they often considered expensive, lack direct interpretability and depth control. To fully utilise seismic measurements, we need to correlate them with borehole measurements.

In this project we aim to reduce the cost and logistic difficulties associated with borehole and surface seismic acquisition to the point where it is considered a routine mineral exploration and deposit definition technique. If we are successful, high spatial resolution 3D mapping of mineral deposits will be possible using many fewer drill holes than are currently required. We will develop methods for rapid data processing and updating of subsurface geological models for resource mapping, mine planning, and safe operation.

Phase 1 Objectives

  • Develop and test methods for cost-effective and safe borehole seismic measurements utilising new types of sensors.
  • Utilise specific geometries of borehole and surface state-of-the-art sensors, recording equipment and highly transportable seismic sources (including currently commercially available) with minimal human involvement.
  • Deploy new data processing technologies and imaging strategies in order to deliver seismic data in a visually impactful and interpretable way.
  • Invert seismic data for rock properties relevant to exploration and mine planning, such as density and elastic properties of the rock
