Ressources Dianor Inc.: Leadbetter Diamond Property Continues to Produce Commercial Sized Diamonds Including a 0.614 and a 0.451 Carat Diamond

VAL-D'OR, QUEBEC--(CCNMatthews - Jan. 16, 2007) - 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 inform its shareholders that it has received preliminary DMS ("Dense Media Separation") diamond results from SGS Lakefield Research for the remaining 29 of the 105 "6 tonne" samples excavated on the Leadbetter Diamond Property during the fall of 2005. Diamond results and location maps for the reported test-pit samples (press releases April 28, July 31, August 30 and November 29, 2006) are available on Dianor's website (www.dianor.com).

Diamond results from 16 surface bedrock samples, 13 shallow overburden (clay, silt, sand) samples in addition to sand and gravel samples from a single pit/trench were received from SGS Lakefield Research and are reported below:

10 of the 16 surface bedrock samples were taken from the Leadbetter Conglomerate and contained 523 commercial sized diamonds (greater than 0.85 millimetres in size) weighing 12.25 carats in 50.91 tonnes of conglomerate bedrock. To date, a total of 3,770 commercial sized diamonds totaling 90.39 carats have been recovered from 351.61 tonnes of outcropping Leadbetter Conglomerate at 66 sites located in the Northern and Central sections of the property. The remaining 6 non-Leadbetter Conglomerate rocks, metasediments and volcanic rocks, totaled 30 tonnes and contained 46 commercial sized diamonds weighing 0.87 carat. Overall, non-Leadbetter Conglomerate rocks totaling 130.31 tonnes were sampled at 26 locations on the property and contained 124 commercial sized diamonds weighing 2.28 carats.

The largest diamond from the current 10 samples being reported was recovered from sample MBP 192 located in the Central Sector of the Leadbetter Diamond Property. The stone weighed 0.614 carat with dimensions of 4.56 mm x 4.53 mm x 3.30 mm and was described as a brown, translucent, dodecahedron, exhibiting 75% preservation. The next largest diamond was recovered from MBP 151 located in the Northern Sector and this stone weighed 0.451 carats with dimensions of 4.28 mm x 3.19 mm x 3.31 mm. This stone was described as an opaque cube exhibiting 85% preservation. In addition, diamonds weighing 0.184 and 0.155 carats were recovered from pits 131 and 108 in the Northern Sector while a diamond weighing 0.113 carat was recovered from pit 166 in the Central Sector. Overall, the majority of the diamonds from the 11 samples have colour, clarity and preservation characteristics consistent with those of the previously reported samples results.

The current diamond results are in line with the previous results for this phase of the surface bedrock sampling program including the recovery of the two largest stones, a 0.667 carat and a 0.614 carat diamond, from two separate geographic areas, the North and Central Sectors. The overall results of this program have also confirmed and established the continuity of diamonds in the conglomerates throughout the surface bedrock exposures and between the drill holes (200m x100m drill hole spacing) in the Northern and Central Sectors which covers approximately half of the extensive outcropping area of the Leadbetter Conglomerate on the Property.

In conjunction with the bedrock sampling program and DMS processing of the samples to recover commercial sized diamonds, 10 diamond bearing conglomerate samples were chosen for diamond liberation studies to determine crushing methods for the optimum recovery of diamonds from the conglomerate. Preliminary results from this ongoing work indicate that high pressure roll crushing can significantly improve diamond liberation.

The Company has also received preliminary results of its sampling of unconsolidated superficial overburden that overlies bedrock in the North and Central sections of the property. The overburden on the Leadbetter property varies from ablation moraine to glacio-fluvial outwash to lake sediment and the property vendor, Mr. Joe Leadbetter had initially demonstrated the diamondiferous nature of the superficial materials in Lena Creek, some 2 kilometers west and down stream from the Leadbetter Diamond Property when he recovered a 1.3 carat gem quality diamond when panning.

The purpose of sampling the superficial materials was to confirm that they were diamondiferous. Initial overburden sampling consisted of excavating thirteen small pits to a depth of 1.0 to 1.5 metres and removing approximately 5 tonne samples from each pit for DMS processing. Two diamonds (greater than 0.85 and less than 1.18 millimetres) were recovered from one of the 13 samples.

In conjunction with the shallow overburden sampling program, a pit/trench was excavated through 6 meters of overburden (glacio-fluvial/glacio-lacustrine material) to bedrock. Four distinct levels of unconsolidated material were recognized and each distinct level/horizon was sampled. The sampled material was washed through a Denver jig and the concentrates produced were shipped to SGS Lakefield for further concentration and final diamond recovery. Results indicate that the diamond content of the material sampled increased with increasing sample depth for the -2.0 millimetre jig concentrates. This may explain the lack of diamonds in the shallow pits excavated in the overburden in the North and Central Sectors.

In the case of the +2.0 millimetre jig concentrates no diamonds except for 4 Congo rounds, or 25% of the spiked diamonds, were recovered. This recovery rate for the spiked diamonds is poor. Further work will have to be conducted in order to determine the best recovery parameters and to adequately test the superficial material on the Leadbetter property.
