NUNAVUT – Montreal-based Stornoway Diamond Corp. says the initial resource estimate for the Qilalugaq project suggests the kimberlite contains 26.1 million carats. The project, on the Rae Isthmus which connects the Melville Peninsula to mainland Nunavut, was acquired from BHP Billiton Diamonds in July 2010.

The Q1-4 kimberlite has an inferred resource of 48.8 million tonnes with an average grade of 53.6 cpht from the surface to a depth of 205 metres. This is the material containing the estimated 26.1 million ct. Another target at the Q1-4 pipe may contain between 7.9 million and 9.3 million ct in 14.1 million to 16.6 million tonnes of kimberlite.

According to Stornoway, Q1-4 is a complex, steep sided, diatreme to root zone kimberlite, with a lobate external shape. It is comprised of five phases of kimberlite, and has been geologically modeled to a depth of 305 metres below surface (see image at TinyURL.com/bqvtk6j). Kimberlite geology has been determined using detailed logging of drill core and results of petrographic studies and includes massive volcaniclastic kimberlite classified as "tuffisitic" kimberlitic breccia, lesser coherent "hypabyssal" kimberlite, and varying proportions of country rock xenoliths.
