4e is more accurate in that it has antimatter doing little Concussion or even Explosive Burning damage. What antimatter does give you is gamma rays and you only get conventional explosive damage from the surrounding matter that the gamma rays ionize.

You'll get that from big antimatter charges in atmosphere that ionize all the air in 750 yards or more. You won't get it in space. If you use enough antimatter (with a hard to determine value of "enough") you will eventually ionize all of your space probe in addition to filling surroundign space with a huge quantity of toxic rads in a very inefficient process.

Small quantities of antimatter have almost no utility in mining..

Try Plastex B instead.
