Kimberlite deposit in Nunavut Canada is far deeper than previously estimated

Peregrine Diamonds Ltd. (TSX:PGD) announced that the CH-6 kimberlite deposit at its Chidliak diamond project, located 120 kilometres northeast of Iqaluit, Nunavut, is twice as deep as it previously estimated.

“The 2017 resource expansion drill program at the CH-6 kimberlite has confirmed that the high-grade CH-6 kimberlite extends from surface to 540 metres below surface, an additional 280 metres below the 260-metre depth of the current CH-6 Inferred Resource announced on April 7, 2017,” the company said in a press release.

The Vancouver-based miner, who had its first kimberlite discovery at Chidliak in 2008, added that caustic fusion microdiamond results released from the 2017 drill program match well with pre-2017 microdiamond results for the KIM-L High Grade and the KIM-L Normal Grade kimberlite units. The KIM-L High Grade were estimated at 4.16 carats per tonne in the Inferred Resource, while the KIM-L Normal Grade were estimated at 2.12 carats per tonne.

These results, the junior mining company says, will form the basis of a revised CH-6 resource estimate whose expectation is that of extending the categorized resource base from a depth of 260 metres below surface to 540 metres below surface.

Peregrine sees potential for doubling the number of diamonds extracted from the site. In addition to this, the company’s President and Chief Executive Officer, Tom Peregoodoff, said that the expectations are high following the recovery of a very rare green diamond. “[The finding] bodes well for the presence of other rare, coloured diamonds that could have a significant impact on the overall average prices eventually received for diamonds recovered from the Chidliak project,” Peregoodoff said.

De Beers to opening world’s largest and richest new diamond mine in Canada

Production at De Beers’ Gahcho Kue diamond mine, a joint venture with Mountain Province Diamond (TSX:MPV), may be delayed from 2015 to as late as beginning of 2017 due to regulatory restrictions that limited shipments to the site this winter, delaying construction. In an interview with Reuters, De Beers’ chief executive Phillipe Mellier said the firm expects to get the necessary permits to truck in more equipment and material next winter. While Canada’s federal government approved the mine in October last year, Gahcho Kué is still waiting on a water license. Situated almost 300 kilometres east of Yellowknife and southeast of the existing Snap Lake diamond project, Gahcho Kué is set to become the world’s largest and richest new diamond mine, according to operator Mountain Province, which owns 49% of the venture. The importance of the mine is also tied to the fact that two of Canada’s major diamond mines — Diavik and Ekati — are approaching the end of their productive lives, and —although it’s smaller— Gahcho Kué could offset the production drop-off.

De Beers and Mountain Province have said that almost 700 workers will be needed during the construction period, with at least 400 to be employed during its estimated 11 years of operations. The mine is expected to produce an average of 4.5 million carats annually. The companies still need to secure the final construction and operational permits before full construction can begin. Public hearings on the company’s applications are scheduled for early May, with permits likely to be issued sometime in the fall.
