Zeolitic ore

Zeolitic ore was a valuable substance found in asteroids.

In 2377, the USS Voyager mined a quantity of high-grade zeolitic ore, which Kathryn Janeway proposed to trade to the Annari for deuterium injectors. The deal fell through after the Annari found Voyager crew members helping their enemies, the Kraylor.
