Stellar holds three diamond licences in Sierra Leone, covering an area of 275 square kilometers.

The Kono project comprises two Exclusive Prospecting Licenses, located in the renowned diamond district of Kono. Underground trial mining has yielded over 4,200 carats at potentially economic diamond grades.

Further to the south, Stellar explored a 9,700 square kilometer area from 2004 to 2007. This area has now been reduced to a single Exclusive Prospecting Licences in the Tongo area, which hosts high-grade kimberlite dykes where grades of up to 100cpht have been yielded from mini-bulk sampling.
