It was compiled from satellite, marine, aeromagnetic and ground magnetic surveys.
2.
The exploration, which included ground magnetic surveys and geophysical data analysis of those surveys, has indicated the potential for several million tons of iron ore.
3.
Where targets are shallow ( < 200 m ), aeromag anomalies may be followed up with ground magnetic surveys on 10 m to 50 m line spacing with 1 m station spacing to provide the best detail ( 2 to 10 m pixel grid ) ( or 25 times the resolution prior to drilling ).
