Reserve & Resource Estimates


Satellite surveying compliant with 43-101 report requirements

Reserve and resource estimates for 43-101 reports for most mineral deposits require accurate surface topography to calculate stripping and mining volumes. Mining and consulting engineering companies around the world are using PhotoSat’s satellite surveying for their 43-101 compliant reserve and resource estimates.

We have been providing engineering quality satellite surveys for reserve and resource estimates for over ten years, and have completed over 1000 surveying projects. PhotoSat’s unique processing system generates elevation data with accuracies better than 20cm in elevation.

Satellite topography for reserve and resource estimates:

  • Reduces the risk for ground surveyors and eliminates surveying delays
  • Satellite data simplifies topographic surveying in remote and hazardous areas
  • Cost-effective alternative to aerial LiDAR and ground surveying

PhotoSat’s satellite surveying data

PhotoSat’s satellite surveying package includes a 1m elevation grid accurate to 20cm in elevation, 50cm or 1m contours, and a 50cm precision satellite ortho photo. Mining companies and engineers use this digital elevation data to reduce timelines for mine reserve and resource estimates.

Proof of accuracy

The elevation accuracy of our satellite surveying has been proven using tens of thousands of ground survey points. View our Proof of Accuracy Reports.
