Dianor Resources Inc.: 1.5 Carat Diamond Recovered from the Leadbetter Diamond Property

VAL-D'OR, CANADA--(CCNMatthews - April 18, 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) has been informed by Kennecott Canada that a 1.5235 carat diamond was recovered during picking of one of the DMS concentrates from sample MBP 136 recently processed at their DMS facility in Thunder Bay, Ontario (press release March 21st 2007). Processing through the DMS plant for all of the four 60 tonne conglomerate samples from the Leadbetter Diamond Property was completed in the past few days. Picking of the DMS concentrates for diamonds is underway at the Kennecott facility and is expected to be completed by mid-May, with a full report and diamond results to follow shortly thereafter.

The 1.5 carat stone is described as light yellow in colour, intact macle that is approximately 7.8mm in its longest dimension. It sits on a 4.75mm square mesh sieve. A photo of the diamond will be available on Dianor's web site later today (www.dianor.com).

The recovery of a diamond greater than one carat is significant as the largest stone recovered from the conglomerate bedrock to date is a 0.667 carat octahedron from sample MBP 101 (press release July 31st 2007). A number of alluvial diamonds greater than one carat have been recovered from creeks in the Wawa area, including a 1.39 carat gem quality stone in a creek draining the Leadbetter Diamond Property. The recovery of the 1.5 carat stone indicates that Leadbetter-type conglomerates are the probable source of these alluvial diamonds. This is also the largest diamond recovered from a bedrock source in the Wawa region.

The four 60 tonne conglomerate samples were collected from the Northern and Central Sectors of the Leadbetter Diamond Property and are replicate samples from selected sites where 6 tonne samples returned varying numbers of commercial sized diamonds.

All aspects of the processing and diamond recovery at the Kennecott Canada DMS facility in Thunder Bay are overseen by personnel from Hatch of Montreal, who were retained by Dianor to independently verify the operations. Hatch personnel have been involved with the design and operation of the three producing Canadian diamond mines since 1994.

A preliminary tonnage estimate on the Leadbetter conglomerate, as outlined by the Phase II drilling, will be reported on shortly. This preliminary tonnage estimate and geological model will provide the basis for defining further, large-scale sampling programs in order to recover sufficient diamonds for pricing and to estimate resources and reserves for the Leadbetter Diamond Project (press release February 20th 2007).

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).
