Dianor Resources Inc. (TSX VENTURE:DOR) is pleased to announce that its two advanced exploration/rehabilitation/closure plans for the Leadbetter Diamond Project near Wawa, Ontario, have been approved by and filed with the Ontario Ministry of Northern Development and Mines. In Ontario this is a major regulatory requirement needed prior to commencing advanced exploration programmes. The plans will be available on the Company's website (www.dianor.com) within the next 48 hours.

The approval of the Northern and Central Decline Advanced Exploration/Rehabilitation/Closure plans is an important milestone in the progress of the Leadbetter Diamond Project since commencement of exploration on the property in April 2005. Dianor Resources Inc. recognizes and thanks, the Town of Wawa, Michipicoten First Nations, Ontario Provincial Government agencies and all those whose co-operation and support of the Leadbetter Diamond advanced diamond exploration project made this approval possible.

The Leadbetter Diamond Project advanced exploration plan is a bulk sampling programme designed to excavate up to 50,000 tonnes of diamond bearing conglomerate from two underground ramps located in the Northern and Central Sectors of the Leadbetter property. Diamonds, rubies, and sapphires from the excavated Archean (2.69 billion years) conglomerate will be extracted by on-site (Dense Media Separation) DMS processing followed by X-ray, grease tabling and optical sorting of the concentrates; gold will be recovered by use of a Nelson concentrator. It is expected that from 12,000 to 20,000 carats of diamonds will be recovered from the conglomerate to determine diamond grade and per carat diamond values (US$). The recovery of rubies, sapphires and gold will provide information on their potential benefit to the economic feasibility of the project (press release August 21st 2008).

Work will now commence with advancing and finalizing the project engineering, obtaining quotes for the supply of equipment and services as well as, additional field measurements and surveying and applying for permits required for the planned on-site facilities and installations. The bulk sampling program is expected to take approximately eighteen months to complete once project facilities have been installed and commissioned.

Upon completion of the bulk sampling program with positive results, this will lead to commencement of pre-feasibility/feasibility studies and include the development of a production rehabilitation/closure plan.

Dianor is an innovative exploration company focused on advancing diamond exploration properties in the Superior Craton of Canada. The Leadbetter Diamond Project, our flagship and most advanced exploration project is geographically well situated and easily accessible, some 12 kilometres north east of Wawa in Northern Ontario. Substantial exploration work has been conducted on the property since 2005 where diamonds, gold, sapphires and rubies are present in 2.697 Ma old Archean Conglomerates (press release January 18th 2007). A preliminary tonnage estimate for this conglomerate is in the range of 549 million to 583 million tonnes (press release July 24th 2007). Additional diamond discoveries including rare purple diamonds were made in 2008 by the Company in rocks of similar type, age (Archean) and geological settings (press release March 3rd, April 10th, & May 13th 2008) in Quebec. The Quebec diamond properties have increased our portfolio of low cost, accessible exploration targets. These diamond discoveries (Ontario and Quebec) are both unique and amongst the oldest diamond bearing occurrences in the world.
