Resolved this finally! To project the geosoft grid with it's native Georeferencing Information (*.GI) you will need Target for ArcGIS. Try projecting the Geosoft Grid using: - Target Surface menu > Grid Properties. - Browse to the grid file - Click next - Modify - CoordSys - Select your Coordinate system, datum and projection - Ok This should create a *.GI file which goes with your grid file. I hope this helps. If not, contact your nearest Geosoft Technical Support Representative.
