The Churchill Diamond Project is comprised of mineral rights to more than 2 million acres located near the communities of Rankin Inlet and Chesterfield Inlet in the Kivalliq region of Nunavut. Work is presently focused on continued exploration of new promising indicator mineral trains and geophysical anomalies as well as the evaluation of four significantly diamond bearing, vertically emplaced kimberlite dykes up to 4 m in width that have returned sampling grades up to 2.04 carats per tonne. A 400 tonne minibulk sample collected from a series of surface pits at the Kahuna dyke this past spring is now being processed for commercial sized diamonds (greater than 0.85 mm on a square mesh sieve).
