Of all the geophysics, it suggests the amount of sulphide we've intersected so far does not explain the magnitude of the gravity anomaly," Novak says.
High values of Bouguer gravity anomaly were encountered due to the presence of near-vertical faulting between areas of contrasting resistivity, and fault zones which may contain more or less highly contrasting density materials.
