The Siku property surrounds the Darby project, where Teck Cominco Limited and Indicator Minerals Inc. discovered nine kimberlite bodies including an 11-hectare pipe. The Siku property strategically positions Diamonds North and Arctic Star Diamond Corp. in a known diamondiferous kimberlite field.

The companies believe the kimberlite field extends onto the Siku property based on indicator minerals, and geophysics. The companies have completed an airborne geophysical survey and numerous targets have been identified for testing.
