Dianor Resources Inc.: Project Manager for the Leadbetter Diamond Property Nominated to Oversee and Advance the Project Forward to Bulk Sampling

VAL-D'OR, CANADA--(CCNMatthews - Feb. 20, 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 retained the services of Mr. Graham Long, P.Geo, as project manager to oversee all aspects of the project and to implement the recommendations put forth by the Qualified Person on Dianor's most advanced exploration project - The Leadbetter Diamond Property situated 12 kilometres north east of Wawa, Ontario.

Mr. Long has over 19 years experience in precious and base metal exploration including diamond exploration experience for the last six years. Mr. Long graduated in 1988 from Concordia University in Montreal, Quebec, with a degree in geology. He began his career working for various junior mining companies working primarily in Quebec and Ontario and joined Agnico-Eagle Mines Ltd. as an exploration geologist with their exploration division in 1994. He then transferred to the Laronde Mine Division where he occupied the position of exploration geologist between 1995-2000. Mr. Long held the position of Exploration Manager Canada for both Agnico-Eagle Mines Ltd and their junior mining company Sudbury Contact Mines Ltd. between 2000-2005 during which time the Lapa Gold Deposit was discovered, before joining Contact Diamond Corporation (formerly Sudbury Contact Mines Ltd.) as Vice President Exploration a position he held until the end of 2006 when Contact Diamond Corporation was acquired by Stornoway Diamond Corporation. Mr. Long is a member of the Quebec Order of Geologists.

The company has received a series of recommendations from its independent geologist and Qualified Person, Mr. Carl Verley for advancing the exploration and development of the Leadbetter Diamond Project for 2007 and beyond. The main recommendations are currently being implemented by the Company. Mr. Verley recommendations are as follows:

- Initiate permitting for up to 1,000 and 10,000 + tonne bulk samples from surface and underground, including planning for an underground decline, possibly to be collared in 2008, in order to extract bulk samples from underground location(s). Permitting procedures are currently being initiated and prepared for submission.

- Planning for a minimum of four - 1,000 tonne surface bulk samples to be taken in mid to late 2007 from the North Sector (2), Central Sector (1) and South Sector (1). The object of this work is to test the conglomerate for large stones as well as to advance the acquisition of larger parcels of stones required for valuation. Implementation dependent on permitting, geological modelling and results of the four "60 tonne" samples.

- In-fill core drilling (NQ and PQ) in the North Sector to be undertaken at 100 and 50 metre centers, in order to better define the horizons within the Leadbetter Conglomerate that contain high diamond counts. This drilling to commence upon receipt of the geological modelling and permitting.

Final bulk sample location(s) will be dependent upon a number of factors including:

- The results of the geological modelling of the Leadbetter Conglomerate as outlined by the Phase II drilling to be completed by the end of the first quarter of 2007.

- The results of the four "60" tonne bedrock samples currently undergoing DMS processing at Kennecott Canada's Thunder Bay facility. Initial diamond results expected in the second quarter 2007.

- The diamond results from the 1,000 tonne surface bulk samples planned for mid to late 2007.

The data generated by the above programmes will provide the basis for defining the location(s) and sample size for further large scale surface and underground bulk sampling programs ( greater than10,000 tonnes) in order to recover sufficient diamonds for pricing and to estimate resources and reserves for the Leadbetter Diamond Project.

As part of the ongoing sampling programmes the following items will continue to be investigated:

- Crushing techniques in order to optimize diamond recovery will be ongoing throughout this process.

- Diamond recovery techniques - studies planned for April 2007.

- Potential by-products, such as gold, ruby and sapphire, which may significantly enhance the economics of the project.

- Overburden testing of glacio-fluvial/glacio-lacustrine material resulted in the recovery of a total of 67 diamonds from three overburden levels (press release January 16th 2007). A more systematic approach to sampling the glacial overburden surrounding the Leadbetter Conglomerate will be designed in order to satisfactorily answer questions concerning the economic potential of this diamond resource.

Carl G. Verley, P.Geo is the Qualified Person responsible for the technical contents of this press release.

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.
