Dianor Inc.: Coloured Diamonds, Including a Blue Coloured Stone Continue to Predominate in Final Three Drill Holes From Mori Joint Venture Property in Ontario

VAL-D'OR, QUEBEC--(Marketwire - Sept. 18, 2008) - THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

(French version available on www.dianor.com) Dianor Resources Inc. (TSX VENTURE:DOR) in conjunction with its joint venture partners Metalex Ventures Limited (TSX VENTURE:MTX) and Mori Diamonds Inc. are pleased to inform its shareholders that it has received complete results for the remaining 3 holes of the 16 NQ drill holes drilled on the Mori joint venture properties, located 3 kilometres north east and north west of the Leadbetter Diamond Property in the Wawa area of Ontario. Theses are the final results of the 2007 drilling campaign conducted on the Mori East and Mori West blocks which returned a preponderance of coloured diamonds (press releases of January 14 and June 25, 2008). The NQ drill cores were processed by autogenous (attrition) milling at the CF Minerals Research Limited laboratory in Kelowna, British Columbia to recover indicator minerals followed by caustic fusion to recover diamonds.

The colour characteristics of the diamonds recovered from the 3 drill holes, MN 07-11, MN 07-12 and MN 07-13, are very similar to those recovered from the first 10 holes, with coloured diamonds making up 56% of the stones, while white and colourless diamonds represented 44% of stone population. Of the coloured diamonds 26.5% were brown; 11.6% were grey; 11.0% were yellow (double that of the previous holes); 5.8% were green. Other colours consisted of one purple and one blue diamond. The blue diamond was described as an included, high intensity blue (scale of 4 out of 4), with dimensions of 296 x 132 x129 microns (1000 microns = 1 millimetre). The colour characteristics of all the diamonds recovered from the 13 holes drilled on the Mori East block consist of 47.5% white stones and 52.5% coloured diamonds with the following order of abundance brown (26.75%), grey (13.88%), yellow(5.72%), green (5.09%) and other colours orange, purple, amber, black, pink, blue (1.09%). Indicator minerals recovered from the diamondiferous drill cores by autogenous (attrition) milling included, G-9 and G-10 garnets, group I eclogitic garnets, picroilmenites, chromites, chrome diopsides and olivines.

Holes MN 07-11, MN 07-12 and MN 07-13 were drilled 2 kilometres to the west of the other 10 holes in the Mori East Block. The main host rocks are Archean age (2.697 billion years old) conglomerates that are visually similar to those conglomerates drilled to the east; however they are situated near a major east west striking shear zone, that may have affected diamond preservation in that area. The largest diamonds were recovered on 0.425 millimetre aperture square mesh screens.

Summary of Diamond Recoveries can be found at the following address: http://media3.marketwire.com/docs/Summary_of_Diamond_Recoveries.pdf

The results continue to demonstrate the persistence of the diamondiferous conglomerate in the area and more specifically indicate the diamondiferous nature of the conglomerate on the Mori East block of claims. The three kilometre long diamond bearing conglomerate band on the Mori East block is situated on the east side of the Mildred Lake Fault and is the faulted eastern continuation of the main diamond bearing Leadbetter Conglomerate located approximately 3.5 kilometres to the south. Exposures of the conglomerate attain thicknesses on surface of up to 180 metres and dip steeply to the north-northwest. Drilling results indicate that the true thickness of the diamond-bearing conglomerate ranges from 87.6 to 121 metres.

Management is very pleased with the overall results of the 2007 drilling programme especially the abundance, variety and size of coloured stones recovered which included rare orange, purple and blue diamonds. A number of coloured stones are of commercial size (greater than 0.85mm) and diamond counts continue to average a promising one diamond per kilogram in a continuous diamondiferous conglomerate. The presence of rare coloured diamonds is believed to be the first such occurrence in Ontario and in conjunction with the Company's recent discoveries of rare coloured diamonds in similar geological settings in Quebec marks a new geological target for coloured diamonds in the Superior Province.

Mr. Carl Verley, P.Geo is the Qualified Person responsible for the technical contents of this press release.

Dianor is an innovative exploration company focused on advancing diamond exploration properties in Canada. The Leadbetter Diamond Project is its most advanced project and is located 12 kilometres north east of Wawa in Northern Ontario. Substantial exploration work has been conducted on the property since 2005 and the Company is planning a HQ drilling programme and is in the process of permitting a 34,000 tonne bulk sampling programme. In addition to diamonds, it contains gold, sapphires and rubies (press release January 18th 2007). New diamond discoveries by the Company in rocks of similar type, age (Archean) and geological settings (press release March 3rd 2008) in Quebec have added further diamond properties to our portfolio of low cost, accessible exploration targets. These diamond discoveries (Ontario and Quebec) are both unique and amongst the oldest diamond bearing occurrences in the world.
