Eldfell-Ashland Energy

Eldfell-Ashland Energy was a mining corporation, from at least 2137-2170. In 2137 CE the Ashland Energy Corporation demonstrated helium-3 extraction on Saturn. There may then have been a merger with Eldfell.

In 2170 (according to Ascension), an element zero freighter exploded over human colony Yandoa, culminating a four-month-long series of industrial accidents. The toxic cloud caused birth defects and biotic births among the survivors.

Paul Grayson under Cerberus's orders caused the crash over Yandoa. The other accidents may have been deliberate too, but only this one is revealed as such.

Trivia
In the E3 2006 demo, Eldfell-Ashland were mining rich eezo deposits on Caleston, making the planet a key source of starship drive core material. Miners working for Eldfell-Ashland were later trapped when the geth attacked.
