Use your data to inform and support your resource classification and drilling decisions

Not all coal seams and quality variables have the same continuity or variability, so investigating drill hole spacing for your data makes sense.

Drill Hole Spacing Analysis (DHSA) lets you understand variations in estimation precision across your deposit for different seams, domains and variables.

Many deposits, variables, and most importantly, a range of geological settings have been analysed using DHSA to obtain the optimal drill spacing information to support resource classification decisions.

DHSA has been implemented internationally by Geovariances for over 12 years. In Australia, DHSA has been applied to coal operations and projects in the Bowen, Surat and Gunedah Basins.
