Kalla III

From Memory Alpha, the free Star Trek reference.

Kalla III is the third planet of the Kalla system.

Kalla III has rich magnesite deposits. The planet is located in Pakled territory, but the Pakled don't know about the magnesite and its value.

Therefore, in 2370 the Duras sisters and their partner Gorta undertook a mining enterprise on this planet, mining over 10,000 kilograms of magnesite. The sisters then betrayed Gorta, took all the ore and left Kalla III for the Ufandi system without their partner. He later was taken aboard by the USS Enterprise-D. (TNG: "Firstborn")
