Shares Issued and Outstanding: 59,932,381 TSX: MPV AMEX: MDM 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 2007 5034 North Lobe Core Drilling Data ------------------------------------------------------------------------- KIMBERLITE DRILL CARATS KIMBERLITE DIAMOND GRADE PIPE HOLE +1.03mm MASS COUNT (carats per (kg) +1.03mm tonne)(1) ------------------------------------------------------------------------- 5034 North MPV-07- 8.695 7,236 136 1.20 Lobe 310C ------------------------------------------------------------------------- 5034 North MPV-07- 25.19 12,773 412 1.97 Lobe 311C ------------------------------------------------------------------------- 5034 North MPV-07- 21.995 7,047 255 3.12 Lobe 312C ------------------------------------------------------------------------- 5034 North MPV-07- 22.50 10,789 345 2.09 Lobe 313C ------------------------------------------------------------------------- 5034 North MPV-07- 23.87 6,773 274 3.52 Lobe 314C ------------------------------------------------------------------------- SUMMARY 102.250 44,618 1,422 2.29 ------------------------------------------------------------------------- (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.
