The earth’s gravity field is minutely affected by variations in the density of rocks in the earth. Those variations can be mapped by measuring the gravity field over an area from aircraft or on the ground. Density changes can arise when there is a change in rock type, mineralogy, or near cross-cutting structures that can control the distribution of mineralisation. Understanding the differences in density often allows us to predict the rock types to provide a more complete understanding of the geology.

HPX uses advanced gravity modelling techniques to ensure that its predictions of both the type of rocks and their locations are more accurate.
