In the preview for the raider, we see ten disks that have ship stats for attack, defense, and hull.

The picture on then looks similar to the mines pictures in this wookiepedia entry.

So it seems we have a new type of mine, possibly just for scenarios, but I'm hoping for regular play.

I'd wager almost anything that they're just gonna be for scenario play

Antimatter mines.

Yeah, but what if they're just waiting to spring a new wrinkle into Epic play? A ship this size and with its mission role would be perfect for carry a small packet of mines.
