Did you know that over the past five years, inverse distance weighting has remained the most common method for modelling coal properties?

Congratulations to Matrix Geoscience Director Kane Maxwell who has recently published a short paper with the Australian Institute of Geoscientists on exactly this topic. Numerous publications in the past have recommended the use of other geostatistical techniques, however inverse distance remains the norm.

Kane’s paper ‘Review of the spatial interpolation techniques used for estimating economic coal properties’ uses data mining to look at conventional coal resource modelling and how JORC resources are currently reported to the ASX.

Special thanks goes to Matthew Dick for his help with the code on this project. Check out the paper by following the link below.
