Dianor Inc.: 1,286 Diamonds Including Pinks Recovered From a Single Rock Sample From the Quebec PEM Diamond Property

VAL-D'OR, CANADA--(Marketwire - May 13, 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) is pleased to announce that diamond results have been received from the SRC laboratory for a further twenty four (24) rock samples from the Company's 100% owned PEM property, located 70 kilometres south of Radisson, Quebec. A single rock sample of conglomerate, weighing 34.75 kilograms, collected from the centre of the PEM property, contained one thousand two hundred and eighty six (1,286) diamonds including twenty six (26) coloured diamonds. The reported diamonds includes six (6) pink; fourteen (14) amber and six (6) yellow coloured stones. Natural fancy coloured diamonds are very rare and expensive. A previously announced, 34.65 kilogram rock sample from an outcrop 1.25km to the north east contained five hundred and forty two (542) diamonds (press release April 10th 2008) and its duplicate sample contained seven (7) purple diamonds. Purple is one of the rarest and most desirable colours. The conglomerates are aged between 2.716 and 2.733 billion years making them unique and amongst the oldest diamond bearing occurrence in the world (press release March 3rd 2008).

The pink and amber diamonds are described by SRC as ranging from faint, very light, to light pink/amber with the majority having octahedroid shapes. The majority of the yellow stones occur as cubes. The size of the coloured diamonds ranged from the smallest at 0.10mm x 0.08mm x 0.06mm to the largest at 0.50mm x 0.48mm x 0.42 mm with the diamonds remaining on the following sieve sizes: +75, +106, +150, +300 and +425 microns. The largest diamond recovered was a colourless, clear octahedron, measuring 2.10mm x 1.54mm x 1.22 mm from this sample (photo on Dianor website at www.dianor.com).

Diamonds results for the twelve (12) diamond bearing conglomerate samples are outlined in the Table below.

Twelve (12) of the twenty four (24) samples were diamond bearing and this ratio of diamond bearing samples (50%) is similar to results received (55% diamond bearing) for the forty seven (47) samples to-date. A total of the ninety eight (98) samples were collected from forty eight (48) sites on the property. The outcropping diamond bearing Ekomiak Conglomerate Formation extends for 11 kilometres along strike and in places is greater than 1 kilometre in width. Individual outcrops measure up to 500 metres by 400 metres in size.

Cumulative results for all diamond bearing conglomerate samples from the PEM are outlined in the table below:

(iii) Results from SRC (caustic fusion) this press release


At each site on the PEM property, two samples were taken; one sample for attrition milling to recover indicator minerals plus diamonds and the second sample for caustic fusion to recover only diamonds. Attrition milling samples were sent to the CF Minerals laboratory in Kelowna, British Columbia while the samples for caustic fusion were sent to the Saskatchewan Research Council (SRC) laboratory in Saskatoon, Saskatchewan.

Management is very pleased with the sample results from its 100% owned PEM property, especially the continuing confirmation of the presence of coloured diamonds and the high diamond counts in widely spaced sample sites. The reconnaissance sampling programme of 2007 on the property was restricted to two small areas, namely a six (6) square kilometre area in the centre of the property and a second location of a two (2) square kilometre area in the eastern end of the property out of a mapped conglomerate area of twenty six (26) square kilometres. Sample sites were widely spaced from 250m to 500 m apart and sample weights were less than forty kilograms (40kg) each. Results to date are promising for this very early stage of exploration and indicate that there is potential for commercial sized diamonds to occur on the PEM property, based on Dianor's geological diamond model. The diamond results confirm Dianor's belief that the Leadbetter Diamond Bearing Conglomerate model is a valid new, low cost exploration model for diamond exploration in the Superior Craton of Quebec and Ontario.


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. 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.
