The estimates push the indicated and inferred resources to 33.8 million tons and 11.3 million tons respectively.

This brings the diamond content of indicated mineral occurences to 56.5 million carats, up from 50.5 in 2009 when the firm last updated the numbers.

Mountain Province is a joint owner of the Gahcho Kue project, with De Beers Canada holding 51% ownership. Gahcho Ku� is the world's largest and highest grade diamond development project.

"All the Gahcho Ku� kimberlites remain open to depth and Mountain Province is in active discussions with De Beers to evaluate a follow-up Tuzo Deep drill program to test the further depth extension of the Tuzo kimberlite between 564 meters and 750 meters," said Patrick Evans, CEO of the company.
