Diamonds Continue to be Recovered on the Dianor/Metalex Joint Venture Property as Diamond Drilling Continues

VAL-D'OR, CANADA--(CCNMatthews - April 27, 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) in conjunction with its joint venture partners Metalex Ventures Limited (TSX VENTURE:MTX) and Mori Diamonds Inc. are pleased to announce the continued discovery of diamonds in conglomerates on the eastern extension of the diamond bearing Leadbetter Conglomerate on their JV property. In addition, diamond drilling of 13 holes at two locations on the JV property has been completed while drilling at a third location has commenced.

Diamond results have been received for 9 of the 21 surface rock samples collected in late 2006 (press release December 4th 2006). These samples were processed by SGS Lakefield in Ontario using the caustic fusion technique to recover diamonds, whereas the remaining 12 samples are currently being processed by combined attrition milling and caustic fusion at the CF Minerals Research facility in Kelowna, British Columbia.

The table of Summary of Diamonds recovered by sieve size - Eastern Part and Western Part - is available at the following address: http://www.ccnmatthews.com/docs/sieve_size.pdf

The largest diamond recovered was a white, transparent, octahedral twin stone with 99% preservation measuring 2.00 x 1.28 x 0.69 millimetres.

The 21 samples were collected from several surface exposures along the length and across the width of the conglomerate band that intermittently outcrops for approximately 3 kilometres in a northeasterly direction from Blueberry Lake in Chabanel Township. The samples in the western part, near Blueberry Lake, were collected in the vicinity of a high strain zone in the conglomerate and returned 18 diamonds in 112.63 kilograms of rock compared to the recovery of 119 diamonds from only 79.6 kilograms of rock on the eastern end of the conglomerate.

Four fences of diamond drill holes, totaling 10 holes, were drilled over a 600 metre length of the steeply dipping conglomerate at the eastern end of the JV property.

A table of Leadbetter Extension Area - Mori North is available at the following address: http://www.ccnmatthews.com/docs/Leadbetter.pdf

All holes were drilled at an azimuth of 150o and at -50o to the south east except drillhole MN-07-02 which was drilled at -65o to the south.

Preliminary geological logging of the drill cores indicates that the drill intersected conglomerates are similar to the S1CO unit of the "Leadbetter Conglomerate" (press release April 23rd 2007).

An area of outcropping conglomerates was also tested in the western part of the JV property 10 kilometres west of the Leadbetter extension. Three drillholes were drilled to obtain geological information on the sedimentary assemblage. Again, from preliminary logging the drill intersected conglomerates are similar to the S1CO unit of the "Leadbetter Conglomerate"(press release April 23rd 2007).

A table of Mori West Area is available at the following address: http://www.ccnmatthews.com/docs/mori_area.pdf

All drill core samples will be sent for a combination of attrition milling and caustic fusion at the CF Minerals Research facility in Kelowna, British Columbia to recover diamonds and indicator minerals.

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 dips steeply to the north- northwest. Preliminary drilling results support these findings. Exploration of the Mori Diamond claims is under a joint venture in which Dianor has a 30% interest along with Metalex Ventures Ltd (press release of August 23, 2005).

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. It is a unique diamond deposit that in addition to diamonds it contains gold, sapphires and rubies (press release January 18th 2007). It is also the oldest in the world being dated at 2.697 billion years old (press release April 4th 2007).
