At PGN Geoscience we focus on two aspects: (1) geology from geophysics using mainly section modelling with GM-SYS; constrained inversion in 3d with VPMG all assembled in 3D environment within gocad. (2) testing the validity of geological interpretations against geophysical data. 

PGN Geoscience constrained inversion geophysical modelling has been used to seek peripheral and deep targets to drill test at Olympic Dam. The modelling aimed to highlight the location of residual gravity anomalies (ie those not explained by known ore). This sort of approach is used in particular for iron ore and massive sulphide exploration and provides high return for any mineralised system where a density or magnetic susceptibility contrast exist between host rock and mineralisation.

PGN Geoscience profile modelling in the Yilgarn has helped build cross sections along an entire greenstone belt (the Agnew – Willuna belt) to take the 2D surface structural interpretation into a 3D crustal model that is useful to make decisions at the district and prospect scale.
