Dianor Resources Inc.: Leadbetter Diamond Grades from Drilling of Main Conglomerate Unit Range from 11.4 to 214.4 cpht for +0.85mm Sized Diamonds from Caustic Fusion

VAL-D'OR, QUEBEC--(Marketwire - July 7, 2009) - 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 final compilation of diamond results from all of the 24 NQ drill holes that were processed by caustic fusion from the Leadbetter Diamond Project located 12 kilometres north east of Wawa in Northern Ontario (press release March 2nd and 31st 2009). Diamondiferous conglomerates were intersected in 18 of the selected 24 drill holes which were caustically fused for diamonds. The results include duplicate samples of approximately 25% of all drill core samples caustically fused to recover diamonds. The diamond bearing conglomerates were intersected at depths in excess of 300 metres below surface in 6 of the holes. The conglomerate intercepts ranged from 11.62 to 228.8 metres, having an estimated true thickness varying from 5.79 to 117.2 metres. The other 6 holes intersected volcanics and/or sandstone-argillite that did not contain diamonds.

The main Archean conglomerate unit (S1C) returned diamond grades ranging from 11.4 to 214.4 cpht for diamonds greater than 0.85 mm in size. Drill intercept lengths for the main conglomerate unit (S1C) ranged up to 228.8 metres and averaged 41.4 cpht for diamonds greater than 0.85 mm in size. The highest diamond grades for the S1C unit were 214.4 cpht for diamonds greater than 0.85 mm intersected over 24.50 metres in hole Chab.05-20.

Diamonds were also recovered from the S1CV and S1CO units; the other two conglomerate units present on the Leadbetter Diamond properties and also intersected during the drilling. The S1CV unit consists of intercalated volcanics, volcaniclastic material and sediments that underlie the S1C unit and was intersected in 5 of the 24 drill holes tested. Hole Chab 05-11 intercepted 14.16 metres of S1CV that contained 11 diamonds greater than 0.425 mm and averaged 58.2 cpht for diamonds greater than 0.85 mm. The other 4 holes intersecting the S1CV unit had 1 or fewer stones. The S1CO unit consists of a weakly layered finer grained sandy conglomeratic horizon that overlies the S1C unit. A total of 6 drill holes intercepted the S1CO unit and all of these intercepts contained diamonds. The best hole, Chab 06-19, contained 82 diamonds greater than 0.425 mm over a drill thickness of 110.26 metres that averaged 26.1 cpht, while in hole 06-34 the 11.62 metre drill interval averaged 61.3 cpht for diamonds greater than 0.85 mm in the S1CO unit.

The diamond results from all of the 24 drill holes are tabulated below at end of the press release.

Compilation of data concerning corundum present in the mini-bulk surface samples is nearing completion. This work indicates that gem quality ruby and sapphire varieties of corundum are present in quantities that warrant further investigation in order to determine the potential contributions that these gems may add to the project, thereby enhancing the overall project economics. Furthermore, preliminary analyses of selected drill core samples indicate that there is relatively high background content for gold in the conglomerate. While gold values range from below detection limit to 8,794 ppb (i.e equivalent to - 9 grams/tonne Au) and average approximately 30 ppb for the S1C unit. At the 98th percentile gold in the S1C unit is 128 ppb in the group of samples tested to date. At that level gold could be a significant by-product, if it correlates with diamond and is recoverable. Further work on the distribution of gold in the conglomerate is therefore warranted.

Management is very pleased with the results which demonstrate continuity of diamond grade and the persistence of diamondiferous conglomerate to depth. While the drill core samples are small and are not representative of a reliable average grade for the conglomerate, they do provide an indication of grade potential. In particular, relatively high grade intervals (- 100+ cpht) within some of the drill holes suggest that there may be high grade zones in the Leadbetter conglomerate. The proposed underground bulk sample program will endeavor to test these zones that could significantly impact the project economics if their grade and diamond quality is maintained in the diamond parcels recovered by this proposed work. In addition, work on the by-product potential and contribution that rubies, sapphires and gold may contribute to the overall project economics will be undertaken.

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 has received approval to proceed with a 50,000 tonne bulk sampling programme forward. In addition to diamonds, the conglomerate contains gold, sapphires and rubies (press release January 18th 2007). New diamond discoveries including rare purple diamonds, by the Company in rocks of similar type, age (Archean) and geological settings (press release March 3rd, April 10th,& May 13th 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.
