Dianor Resources Inc./Update: Leadbetter Diamond Project


Dianor Resources Inc. (TSX VENTURE:DOR) is pleased to update its shareholders on the continuing advancement of the Leadbetter Diamond Project towards bulk sampling. Since early summer, the Company has assembled a team of consultants including experts in the environmental, mining engineering and mineral processing fields to assist in the preparation of documents and field studies for the permit/mine closure plans for the bulk sampling program. Required documentation is near completion and the Company expects they will be submitted within the coming weeks to the Ministry of Northern Development and Mines (MNDM).

The bulk sampling programme is designed to accumulate numerous parcels of diamonds from various segments of the Leadbetter conglomerate from the Northern and Central Sectors to determine diamond grade and pricing that can be used to appraise the feasibility of the project. The Company anticipates during the programme that approximately 34,000 tonnes of diamond bearing conglomerate will be extracted and yield between 7,000 and 13,000 carats of diamonds.

The bulk sampling program will include the development of two underground ramps from surface; one located in the Northern Sector and the other in the Central Sector of the property. Detailed geological mapping of the property during the summer established the surface geological boundaries of the various diamond bearing units and helped determine the location of the ramp sites and portals for the bulk sampling. Development (drilling/blasting/mucking/extraction) of the two exploration ramps will be completed consecutively and not concurrently, commencing with the Northern ramp first. Ramp advance of 2.9 meters per day shift is planned. Each ramp will produce between 15,000 and 19,000 tonnes of diamond bearing conglomerate for processing, yielding between 3,500 and 6,500 carats of diamonds. The Northern ramp will be at a 15% decline from the surface and extend for 453 meters with dimensions of 4 metres in height by 4 meters in width. The Central ramp will be identical to the Northern ramp, except for its length which will measure 333 meters.

A total of 36,000 tonnes (21,000 t and 15,000 t from the Northern and Central ramps respectively) of material, including the 34,000 tonnes of diamond bearing conglomerate will be extracted during the 18 month bulk sampling program. Approximately 130 tonnes of diamond bearing conglomerates will be produced from the ramp daily and processed through an on-site Bulk Sampling Plant to produce a DMS concentrate. The sampling plant will have the capacity to treat material at a rate of 10 tonnes- per- hour. The DMS concentrate will then pass through an x-ray sorter to produce a diamond concentrate which will be shipped off site to an independent laboratory for final recovery, weighing and cleaning of the diamonds.

The results of processing four "60 tonne samples" of diamond bearing conglomerate at the Kennecott Canada facilities in Thunder Bay in 2007, clearly demonstrated that liberation and recovery of diamonds from the Leadbetter Conglomerate utilizing conventional technology is highly efficient. DMS diamond recovery efficiency, based on carats, was 98.5%. The diamond industry accepted 'design' figure is 97%. (Press releases April 18th, April 23rd 2007and August 28th 2007). Diamond grade and diamond distribution data for each day's production will allow for a detailed distribution of diamonds throughout the conglomerate to be made and delineate zones/horizons having high diamond content for further investigation and sampling.

In addition to the bulk sampling, an infill diamond drilling program totalling 6,000 meters is planned for the Northern Sector of the Leadbetter Diamond Property. The drilling is expected to commence during the latter part of the first quarter of 2008. The drill program will consist of 30 vertical drill holes at 50 meter spacing, totalling 6,000 meters of HQ (47.6mm) core. The HQ drill core will be processed to recover not only diamonds but other minerals including corundum and indicator minerals to help determine their association and distribution with the diamonds. The drilling is designed to intersect the diamond bearing Leadbetter Conglomerate to further define its continuity, thickness, diamond content, diamond variability and geotechnical data. The geological and geotechnical data generated by the drilling will further assist in finalizing and fine tuning the bulk sampling program.

The bulk sampling and infill drilling programs above are based on the recommendations outlined in the 43-101 compliant report "Preliminary Tonnage Estimate for the Diamondiferous Conglomerates of the Leadbetter Diamond Project" dated August 29th 2007 and prepared for Dianor Resources Inc. by Verley, D'Amours and Martel. Mr. Carl Verley, P.Geo will be the independent Qualified Person responsible for all reporting aspects of the bulk sampling and drilling programs.

Hatch has been retained by Dianor to plan and commission the 10 tonne-per-hour Bulk Sampling Plant including a 20 tonne-per-hour Dense Media Separation (DMS) plant in order to treat the large bulk sample planned for 2008-2009. Hatch is in the business of supplying consulting and engineering expertise to the mining and metallurgical industries among others. The senior consultant who will be overseeing Dianor's work is Mr. Mike Rylatt who is a diamond processing consultant with more than 25 years experience in the diamond industry in the areas of design, commissioning and operations. Mr. Rylatt has been involved with the Canadian diamond industry for 14 years at the Ekati and Jericho mines and has been involved with the design and commissioning of three sampling and two production plants. Hatch most recently completed and commissioned a 10 tonne-per-hour DMS plant for Stornoway Diamond Corporation at their Foxtrot property in central Quebec.

GENIVAR of Val-d'Or, Quebec has been retained by Dianor to offer mining engineering technical support for the bulk sampling program, specifically in completing a closure plan report required for permitting. GENIVAR provides a comprehensive range of engineering, environmental and construction services and is active in a variety of sectors, including mining and mineral processing. Over the past few years, they has been involved in several mining projects notably in Canada and elsewhere in the world and is currently managing a portfolio of projects exceeding $1 Billion .

Dianor retained the services of experts in the environmental field to conduct the various studies required for permitting. Dickson Management Services of Wawa and Great Lakes Environmental Services of Sudbury provide services relating to environmental permits, assessments, approvals, hydrology, erosion and sediment control etc.

Mr. John Ryder, 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. 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).
