Where to get High-Value Mark for Arrest?

With the buff to make them give 1 mil it sounds like a pretty good gold farm if they're able to be acquired in at most like 20 mins. They're no where in access info, otherwise this wouldn't be needed.

I got those from Fortress Special Operation Missions the ones where you need to defend the objective for max 21 waves, don't know the exact name because currently I'm not online.

Killing elites in special operations, they sometimes drop them. Very few and rare though...

Do Block Kuiper Mine either on White-Night Gultch or Sterile Lands, it's not a high chance drop tho but it's cool now, before patch was like 10k gold the blue one and 100k the pink one was TRASH.

Now it's 100k blue and 1 mil pink :D
