I've scanned absolutely everything in the game except for the Phaaze scans. However, I can't find a Puffer Mine... the Logbook FAQ states that they're found in the Airshaft at Pirate Research and it doesn't say they're missable... but there's only a lone phazon-energy ball thing...
Don't tell me Puffer Mines are a one-time scan. :< --- http://backloggery.com/vinchenz_rock/sig.gif http://www.youtube.com/user/VinchenzRock

If I remember correctly, they're in a room where you shoot four yellow switches which causes a Wall Jump surface to appear. I think you have to take out four of those Crawl Tanks before the Puffer Mines appear.
