Commercial-Sized Diamonds Recovered on Dianor/Metalex Joint Venture Property as Extension to Leadbetter Diamond-Bearing Conglomerate Verified.

VAL-D'OR, CANADA--(CCNMatthews - Dec. 4, 2006) - 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 Mori Diamonds Inc. are pleased to announce the discovery of the eastern extension of the diamond-bearing Leadbetter Conglomerate on their joint venture property. Diamond results from the Saskatchewan Research Council (SRC) and CF Mineral Research Ltd laboratories for five surface rock grab samples collected on the Mori Diamond Property confirm that the three-kilometer (3 km) long outcropping conglomerate is diamond bearing.

The samples processed by SRC (RS40174 & RS40175) used the caustic fusion technique to recover diamonds, whereas CF Minerals Research processed samples by attrition milling and caustic fusion of heavy mineral concentrates. Exploration of the Mori Diamond claims is under a joint venture in which Dianor and Metalex each have a 30% interest (press release of August 23, 2005).

The grab samples were collected from several surface exposures of conglomerate that forms a three-kilometre band outcropping in a northeasterly direction from Blueberry Lake in Chabanel Township. The diamond-bearing conglomerate band is situated on the east side of the Mildred Lake Fault, being the right lateral extension of the diamond-bearing conglomerate found on Dianor's Leadbetter Property which is offset in the order of 3.4 kilometres. Exposures of the conglomerate on the Mori Diamond Property attain thicknesses on surface of up to 180 metres and dip steeply to the north-northwest. It is open both to the east and the north. Geological reconstruction of the diamond-bearing conglomerate on the joint venture's Mori Property and Dianor's Leadbetter Property by removing the effects of the lateral faulting indicates that the original conglomerate outcropped along strike for a length in excess of 4.7 kilometers. Diamond results from surface rock sampling indicate that it is diamond bearing along the complete length of the outcrop areas (Mori and Leadbetter Properties). The recovery of a commercial-sized diamond, close to 1/10th of a carat (0.093 carats) in an 11.78 kilogram grab sample of surface bedrock on the JV Mori property is encouraging for the commercial sized diamond potential of the property.

Caustic fusion processing of two grab samples (RS40174 & RS40175), collected from the conglomerate on the eastern part of the conglomerate band have diamond counts averaging 55 and 31 diamonds per ten kilograms. An 11.78 kilogram sample processed by attrition milling from the same site as sample RS40174 returned an average of 17 diamonds per ten kilograms including a 0.093 carat diamond. Sample RS40173, collected from a high strain zone in the conglomerate at the western end of the conglomerate band on the Mori Diamond Property, returned one diamond from attrition milling.

Subsequently, 21 grab samples of the conglomerate were collected along the length and across the width of the conglomerate band. Half of the samples will be processed to recover diamonds by caustic fusion and half by attrition milling to recover diamonds as well as diamond indicator minerals. Results for these samples are expected in the first quarter of 2007. Management is planning a diamond-drilling campaign to test the down dip extent and diamond potential of the conglomerate. This phase of work is expected to commence shortly.
