Using Oasis Montaj viewer you can export the geosoft .grd file to one of the following formats: .gxf, pcidisk, surfer grd or geotiff; then use Grid Translator Pro (GTP) to import the exported dataset to Vertical Mapper.
GTP is not a free tool; however you can get 30 days fully functioning copy at:

GTP supports also batch import to Vertical Mapper grid format (numeric and classified).
Regarding the .grd extension there are multiple GIS products that use that extension (Surfer, Geosoft, vertical Mapper, etc.) but the format itself is different from a product to another.

Hello all,
I'm looking for a good (free) way to import Geosoft .grd's into MapInfo. Geosoft has a MI plug-in but you have to have MapImagery also (which I don't have).
What I am trying to import are the USGS magnetics grids. These are published in .grd format. The grids load just fine into the free Oasis Montaj viewer. The problem is that MI dosn't seem to support any of the grid export options of this viewer.
Yes it says that MI 7.0 supports .grd format in the open file dialog. The files are visiable but when an attempt to open this made then MI says that they are an unrecognized format.
I imagine that some other MI users have imported this same data, so how did you do it?
I'm sure everyone feels my pain. ;-)
