Gahcho Kue's Geotechnical Drilling Underway

RAPAPORT... In its project report on the Gahcho Kue diamond mine in Northwest Territories of Canada, Mountain Province Diamonds anticipates approximately 110 truckloads of mining materials, equipment and fuel will be delivered to the site in the next two weeks with final supplies for the year arriving before the end of March, at which time the winter ice road will close.

A geophysics team was mobilized to Gahcho Kue in January and completed a ground-gravity survey for 15 high-priority drill targets. There were 3,230 stations surveyed on 13 grids over those targets and the company stated that the data gathered there should support drill-hole placement for final exploration. Core drilling of the first phase  is expected to begin before April and a second core drill rig is now being mobilized to the site. Based on the success of the first-phase drill program, another 14 priority geophysical targets may be drill tested.

Geotechnical drilling related to the planned surface infrastructure at Gahcho Kue  started in February and will include drilling  33 sonic holes and 31 core holes before this project is completed in late April.

At the project's Tuzo Deep section, a geological report was completed in January and a grade report was completed in mid-February by  De Beers Canada in its capacity as the operator of the Gahcho Kue project. The data  established the geological continuity of the Tuzo kimberlite from the probable reserve portion --from surface to 300 meters-- to a depth of 564 meters and also provided a tonnage and grade estimate.  The reports offered compelling evidence that the kimberlite units present below 300 meters are the same as those present in the probable reserve portion and also that similar grades were estimated at that depth, according to Mountain Province.

Since the De Beers technical report did not classify Tuzo's potential resource in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) guidelines, Mountain Province retained an independent qualified person to complete a quality assurance and quality control review of this data for public release.

"There is a high level of activity at Gahcho Kué, which is reflective of the significant advances made in preparation for development of the first diamond mine," said Patrick Evans, Mountain Province's president. "Encouraging progress continues to be made with the permitting and we expect an updated NI 43-101 resource statement for the massive Tuzo kimberlite in second quarter. Already the world's largest and richest new diamond mine, Gahcho Kué is set to get even bigger with the inclusion of the Tuzo Deep potential resource. With ground geophysics now completed we're also gearing up to start exploration drilling of the first 15 new targets in immediate proximity to the four known kimberlites at Gahcho Kue. If successful, our winter exploration drill program may offer further exciting resource upside."
