Dianor Resources Inc.: 121 Purple Diamonds Confirmed in Surface Rock Samples From the Quebec PEM and Ekomiak JV Diamond Properties

VAL-D'OR, QUEBEC--(Marketwire - Aug. 7, 2008) - THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

Dianor Resources Inc. (TSX VENTURE:DOR) in conjunction with its joint venture partners Metalex Ventures Limited (TSX VENTURE:MTX) and Wemindji Exploration Inc. (Wemex) are pleased to announce receipt of final diamond results for one hundred and ninety one (191) reconnaissance surface rock samples taken on the Joint Venture's Ekomiak II; IV; V; VI; and VII properties and on Dianor's 100% owned PEM property in the James Bay region of Quebec. Diamonds were recovered from all of the six (6) sampled properties spread over a large geographical area of James Bay that is easily accessible by road. A review of the diamonds recovered to date by CF Minerals of Kelowna, B.C. confirmed the presence of 121 purple coloured diamonds in eight (8) samples from three (3) properties (Ekomiak V; VII and PEM).

A single surface rock sample from the Ekomiak V property weighing 36.66 kilograms (approximately 81 lbs) contained 94 purple diamonds in addition to numerous other coloured diamonds. The Ekomiak V samples also returned an average coloured diamond content of brown (30%), purple (22%), grey (15%), yellow (9%), green (5%), and amber (2%). Seventy eight percent (78%) of the diamonds recovered and described from the properties were coloured diamonds. They ranged from brown (38%), purple (10%), grey (10%), yellow (10%), green (7%), amber (2%) and pink (1%). Natural fancy coloured diamonds are very rare and expensive with purple as one of the rarest and most desirable colours. The main host rocks are conglomerates of Archean age, between 2.716 and 2.733 billion years old, thus making these Quebec diamond discoveries both unique and amongst the oldest diamond bearing occurrence in the world (press release of March 3, 2007).

Ninety two (92) of the one hundred and ninety one (191) reconnaissance surface rock samples were diamond bearing and a total of 4,592 diamonds were recovered. The results show that on average, forty eight (48%) percent of the rock samples from all the sampled properties were diamond bearing compared to eighty two (82%) percent of the rock samples from the Ekomiak V property.

Cumulative results for all diamond bearing surface conglomerate samples from the six (6) sampled properties are outlined in the table below:

The largest diamond recovered was a colourless, clear octahedron, measuring 2.10mm x 1.54mm x 1.22 mm from a sample taken on the PEM property (May 13th 2008 and photo available on Dianor website at www.dianor.com. The coloured diamonds recovered ranged in size from 0.075 to 1.06mm and were present on all screen sieve sizes from +75 to +850 microns.

The majority (108) of the surface rock samples 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 other eighty three (83) rock samples were caustically fused for diamonds only at the SRC diamond laboratory in Saskatoon, Saskatchewan (press releases March 3rd, April 10th and May 13th 2008). The Company's 100% owned PEM property; the Ekomiak IV; V; and VII JV properties are located between seventy (70) and ninety (90) kilometres south of Radisson while the Ekomiak VI property is located approximately two hundred (200) kilometres directly south of Radisson, Quebec. The Ekomiak IV property is located some 75 kilometres ENE of the PEM property and all the properties sampled are readily accessible by road.

Indicator minerals (approx. 20,000) were recovered through the autogenous (attrition) milling of the outcrop samples of conglomerate and microprobe analyses of approximately two thousand grains identified kimberlite and diamond indicator minerals (DIM's) including Olivine, Pyrope (G9 and G10) and Eclogitic (G1) garnets; Chromites; Clinopyroxenes and Picroilmenite. Plotting and evaluation of the data shows that 75% of Olivines and 25% of chromites plot in the diamond stability field with the picroilmenites plotting in the compositional range normally associated with North American kimberlite. Microprobe analyses and interpretation by CF Minerals also indicated that certain minerals grew in a diamond environment with large diamonds. The indicator mineral assemblages suggest a proximal diamondiferous primary source rocks for the diamonds in the conglomerates. A pyrope G10-10 garnet was identified in one of the four (4) samples taken from Ekomiak VI where geological mapping by the Quebec Government delineated an area of twenty (20) to thirty (30) square kilometres of conglomerate.

Management is encouraged with the sample results especially the percentage content of the rare purple diamonds; size of the coloured stones including a commercial sized white diamond from "small" 30 kilogram (70lb) rock samples taken from the surface of large outcrops on the PEM and Ekomiak V properties and the confirmation that the purple diamonds occur in eight (8) samples. The high percentage of coloured diamonds indicates that the James Bay area of Quebec has the potential to be a premier area for coloured diamonds in North America if not the world apart from the Australian Argyle mine where coloured diamonds are mined and marketed by Rio Tinto. Management is also encouraged that the reconnaissance sampling programme of 2007 proved the presence of diamondiferous conglomerates on all of the six properties. Also, in the current era of high energy prices, all of the six properties are close to and cut by highways and as the diamond bearing rocks are exposed on surface, current and future activities fits a low cost exploration model for diamond exploration and exploitation compared to other diamond exploration areas of Canada.

Mr. John Ryder, 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 6,000 metre 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.
