TORONTO & NEW YORK, March 12, 2013 /CNW/ - Mountain Province Diamonds Inc. 
("Mountain Province", the "Company") (TSX: MPV, NYSE MKT: MDM) is pleased to 
provide an update on recent developments at the Gahcho Kué ("GK") project, a 
joint venture with De Beers Canada Inc. ("De Beers").

"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 President and CEO. "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 Q2. 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 GK. If successful, our winter exploration drill program may 
offer further exciting resource upside."

2013 winter ice road

The 2013 winter road reached the GK project site at Kennady Lake on March 2, 
2013, with the first loads arriving on March 4, 2013. Over the next two weeks 
approximately 110 truckloads of materials, equipment and fuel will be 
delivered to GK. The final deliveries are expected by before the end of March, 
2013.

Permitting

The public record for the environmental impact review closed successfully on 
January 3, 2013. The report and recommendation from the Gahcho Kué Panel is 
now awaited. On completion, the Panel report will be submitted to the Minister 
of Aboriginal Affairs and Northern Development who has the authority to 
approve the development of the first diamond mine at GK. While both the Panel 
report and Ministerial approval are awaited, the Mackenzie Valley Land and 
Water Board has opened the public registry to facilitate expeditious 
processing of the GK permits.

Mr. Evans commented: "The project development schedule remains subject to 
final regulatory approval. While there is a high level of public and 
government support, delays in final regulatory approval could impact the 
development schedule. Shareholders will be kept informed of further 
developments following receipt of the report of the Gahcho Kué Panel".

Tuzo Deep

The Tuzo Deep geological report was completed in January, 2013 and the Tuzo 
Deep grade report was completed in mid-February, 2013. These reports were 
prepared by De Beers in its capacity as the Operator of the GK project to 
establish 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 
to provide a tonnage and grade estimate for Tuzo Deep.

The reports provide 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 depth.

The De Beers technical report does not classify the Tuzo Deep potential 
resource in accordance with the Canadian Institute of Mining, Metallurgy and 
Petroleum (CIM) guidelines. Mountain Province is therefore retaining an 
independent qualified person (QP) to complete a quality assurance (QA) and 
quality control (QC) review of the De Beers geological and technical reports 
with a view to presenting to shareholders an updated independent National 
Instrument 43-101 resource estimate for the Tuzo kimberlite. It is expected 
that this report will be released during Q2 2013.

Geophysics

A geophysics team was mobilized to GK in January, 2013 and completed a ground 
gravity survey over 15 high-priority drill targets. There were 3,230 stations 
surveyed on 13 grids over the 15 targets. The results from the survey will 
support final exploration drill-hole placement.

Geotechnical drilling

Geotechnical drilling related to planned surface infrastructure at GK 
commenced in February, 2013 and is expected to be completed before the end of 
April. A total of 33 sonic holes and 31 core holes will be drilled.

Exploration drilling

Core drilling of the first phase 15 priority geophysical targets is expected 
to commence before the end of March. A second core drill rig is being 
mobilized to site and the first phase drilling is expected to be completed by 
the end of April. Based on the success of the first phase drill program, up to 
a further 14 priority geophysical targets may be drill tested.

Mountain Province Diamonds is a 49% participant with De Beers Canada in the 
Gahcho Kué JV located at Kennady Lake in Canada's Northwest Territories. The 
Gahcho Kué Project consists of a cluster of four diamondiferous kimberlites, 
three of which have a probable mineral reserve of 31.3 million tonnes grading 
1.57 carats per tonne for total diamond content of 49 million carats.

Gahcho Kué is the world's largest and richest new diamond mine development. A 
December 2010 feasibility study filed by Mountain Province (available on 
SEDAR) indicates that the Gahcho Kué project has an IRR of 33.9%.
