NSDM - earnin' $ by sellen other companies diamonds... on their substandard website... and trying to use the $ to find diamonds in Manitoba (NO KIMBERLITE, NO DIAMONDS to speak of...)!
DMXP - at least something to speak of - even Paul Harvey spoke of us...
NSDM has diamonds from other compamies. You might check out DMDD for real diamond mining potential. Delta's claims might be too small to be profitable.
