Mizainite

Mizainite is a metallic ore.

By 2323, the Bajorans had started to supply the Cardassians with mizainite mined from Bajor's moons. 

In 2369, Rom told Quark that he had heard from Krax that Stakoron II in the Gamma Quadrant had rich deposits of mizainite. 

According to, Holna IV had enough mizainite deposits to keep the Dominion's shipyards running for years during the Dominion War.
