    Continuity between 5034 East and North Lobes Confirmed

    TORONTO and NEW YORK, July 16 /CNW/ - Mountain Province Diamonds Inc.
("the Company) (TSX: MPV, AMEX: MDM) today announced the results of the
5034 North Lobe large-diameter core drilling program conducted during the
summer of 2007.
    Under this program five large-diameter core holes were drilled at the
northern, land based portion of 5034 North Lobe recovering approximately
36.7 tonnes of kimberlite. Sample processing took place at De Beers' Grande
Prairie facility with diamond recovery carried out at De Beers' GEMDL facility
in Johannesburg. The program was designed to collect approximately 100 carats
from the North Lobe to support the macro diamond size distribution inferred
from earlier micro-diamond sampling. Selected sections of the recovered drill
core were crushed to -6mm and screened at a nominal bottom cut-off of 1.0mm.
These are the first macro-diamonds from the 5034 North Lobe. Approximately
80 carats were recovered at a nominal 1.5mm cut-off, and 102 carats at a 1.0mm
nominal cut-off. The results at a 1.00mm nominal cut-off are presented in
Table 1 below.Table 1

    (1) Grade presented for illustrative purposes only.According to De Beers Canada, confirmation of the kimberlite continuity
between the 5034 North and East lobes provides sufficient confidence to be
able to extrapolate the diamond revenue modeling from the 5034 East Lobe,
which is in the indicated mineral resource category, to the North Lobe with a
much reduced diamond parcel from the North Lobe. The sampling program was not
designed to determine diamond grade or diamond value in 5034 North Lobe.
    Located in Canada's Northwest Territories, Gahcho Kué is one of the
largest new diamond mine under development globally. The project consists of a
cluster of three primary kimberlites with an indicated resource of
approximately 14.4 million tonnes grading at 1.64 carats per tonne
(approximately 23.6 million carats) and an inferred resource of approximately
17 million tonnes grading at 1.35 carats per tonne (approximately 22.9 million
carats). Gahcho Kué is currently in the permitting and advanced exploration
stage of development.
    Mountain Province Diamonds (49 percent) is a joint venture partner with
De Beers Canada Inc (51 percent) in the Gahcho Kue project. De Beers is the
operator of the project and can be called on to fund the project through to
commercial production.
