Top-Rock

Depth Mapping to top of Bedrock

WHAT IS TOP-ROCK?

TOP-ROCK utilises seismic refraction tomography to generate a detailed 3D model of the near-surface velocity variations within a project area. This data can be generated directly from a seismic dataset or can be further optimised through calibration with available drilling. The output wireframe can identify vertical changes in the near-surface velocity down to a few metres of resolution.

WHY IS THIS IMPORTANT FOR EXPLORATION?

Velocity variations in the near surface are directly related to seismic rock competency and hence, a detailed map of the velocity field provides a high-resolution map of near surface conditions, highlighting key features such as the position of depositional structures, alteration and bedrock lithology changes.

WHY THIS IS IMPORTANT FOR GEOTECHNICAL?

TOP-ROCK can define the extent of free-dig material and provide important input for the design of pit-wall slopes, infrastructure placement and engineering specifications.

WHY THIS IS IMPORTANT FOR ORE RECOVERY?

TOP-ROCK can help define the extent of oxide material and produces a physical wireframe to assist in analysis and calculation of ore recovery.

WHY IS THIS IMPORTANT FOR HYDROGEOLOGY?

TOP-ROCK can help define the extent of oxide material and produces a physical wireframe to assist in analysis and calculation of ore recovery.
