    TORONTO and NEW YORK, Aug. 6 /CNW/ - Mountain Province Diamonds Inc.
("the Company) (TSX: MPV, AMEX: MDM) today announced preliminary results from
the Tuzo large-diameter bulk sampling program conducted last winter. As
previously announced, a 25.13 carat gem quality diamond of excellent shape and
clarity and good colour was recovered during this program. This diamond has
been independently valued at $17,500 per carat, putting the diamond value at
approximately $440,000.
    The Tuzo bulk sampling program was designed to recover approximately
1,500 carats. Combined with the approximately 600 carats recovered from Tuzo
during prior years' exploration, this should be sufficient to develop a
diamond revenue model for the Tuzo kimberlite pipe. Once all the results are
available, the Tuzo diamonds will be valued by the Gahcho Kué project
operator, De Beers Canada. Mountain Province Diamonds has retained WWW
International Diamond Consultants to conduct an independent valuation of all
the Gahcho Kué diamonds, including the recently recovered Tuzo diamonds.
Following completion of the Tuzo diamond revenue model, it is anticipated that
the Tuzo resource will be upgraded to the "indicated mineral resource"
category.
    "We are very pleased with the results of the Tuzo bulk sampling program.
Our target of 1,500 carats has been exceeded and we believe the 25.13 carat
diamond is the largest gem quality diamond ever recovered from a Canadian
diamond exploration drill program", said Patrick Evans, President and CEO of
Mountain Province Diamonds.
    To extract the Tuzo bulk sample, two 24-inch large-diameter drill rigs
were used. A total of nine holes were drilled, with seven holes to depths
between approximately 100 and 130 meters and two holes to depths of
approximately 300 meters. The preliminary results listed in Table 1 below are
for eight of the nine holes drilled. The results for hole MPV-08-319L, which
was one of the deep holes drilled, are still pending. A total of 18,893
diamonds have so far been recovered from 715.6 tonnes of kimberlite.Table 1
