Resource Estimation and PEA

APEX has the in-house capability to create three-dimensional (3D) models that fully incorporate geological, structural, mineralization, and geophysical data from a variety of data sources to enable a better understanding of an ore deposit. Our staff has prepared resource estimations and Preliminary Economic Assessments (PEA) for various commodities including gold, diamonds, base metals, rare earth elements, lithium brines, potash, gypsum, salt, iron ore, aggregate and frac sand (proppant).

Resource Estimations

  • Ordinary kriging, inverse distance weighting, indicator kriging methodologies
  • Wide range of commodities and deposit types
  • Geostatistical analysis of a project's mineral resource classification
  • NI 43-101, JORC and SAMREC compliant
  • 3-D PDF’s and fly-throughs for promotional purposes



Three-dimensional model showing the gold mineralization at the Jumping Josephine Property, resource modelling was completed for OREX Minerals. The above image is also available as a 3-D pdf.
