As I'm not much of a miner I haven't had any issue with this until now. I'm trying to unlock DRG and through some googling I found a post that said excavation points don't spawn in retail locations. They linked to a map of the locations but the image had been removed. I can't seem to find something that shows me where the possible spawns are. I just want to unlock DRG but it's making it a bit of a nightmare. I've been running around the zone for an hour but I haven't seen one yet. Any help would be appreciated.

Here is the map I used when I did the DRG quest. The blue circles are the spawn points for the egg.

That's the one I've been using also. I guess i'm just doing it wrong. Thanks.

And, found it! It spawned right after I responded to you. Thanks again!
