Elesium ore
From Tardis Wiki, the free Doctor Who reference
Elesium ore was a mineral used as a component in the fuel that blasted a ship into hyperspace. Fuel with a higher percentage of elesium ore was more efficient and safer. Studies showed that the risk ratio of pilots using elesium-enriched feud dropped by 6-7%, and therefore about 40 million fewer human pioneers got splattered every week.

Had he been successful in obtaining mining rights before others also discovered the rich deposits, his return on investment would have been significantly increased. (AUDIO: The Prisoner's Dilemma)
