==================== Type: Infocard Bug: Infocard for Torfaen mentions BMM has expressed interest in mining "terraforming gases" which is clearly a mistake, as the miners are Planetform. ====================
Well, it's strange that this field is home to a near infinite supply of terraforming gases as the infocard states, yet it says BMM, an ore mining corporation, has expressed interest in something that Planetform would be interested in, not them, and the miners in the field are owned by Planetform after the local mining station was sold to Planetform by the BMM and they shipped out to a smaller station in Cambridge.
"A large Asteroid field rich in noble gases, the Torfaen Asteroid Field is a newer resident of the Poole system. Having settled after being pulled away from the far reaches of the Omega-49 system, the growing Torfaen has been targeted by Planetform as a source of terraforming gases to last centuries as the field continues to grow."
BMM and PFI have a joint operation. See Douglas Station in Omega-3. It's where the Terraforming Gasses are produced (by BMM).
I believe that both the miners and the infocard try to represent that joint-ness between the two corporations.
Who mines it is rather irrelevant, but I would guess that BMM are expert space-harvesters, be it mineral or gas.
