About Four Million Tons of Ore Averaging 4.1% Graphite Were Outlined on National Graphite Corp Acquisition
The following is drawn from due diligence associated with the acquisition the Quebec claims and a report prepared by:

Dun Raven Mines Ltd. holds a group of 20 claims covering 1928 acres in Thorne and Clarendon townships, Pontiac county. The property is easily accessible Shawville located about 10 miles to the south on a good road and several secondary roads traversing the claims. It can also be accessed from a roadfrom the village of Bryson about 10 miles northwest of Shawville.
Shawville and Bryson are located about 10 miles apart along Highway 8, about 50 and 40 miles from Hull and Ottawa. The Canadian Pacific Railways maintains daily service from Ottawa to both places.
The topography of the southern group of claims is relatively flat and open whereas the northern part is more rugged and wooded. According to Sabourin (P.R.307), the area is underlain by rocks of the Grenville series and various types of made up of crystalline limestone and various types of gneisses, in places injected with granite.
During the course of exploration work for radio-active minerals known to be presenton the property, graphite was discovered in 1954 on the south flank along the boundary of claims 7 and 8A, in the north half of range XIII of Clarendon Township. A series of trenches were put down on the side of the hill and a combined self potential and magnet meter survey was carried out on the property to determine the extent of the graphitic mineralization. Two large and two smaller anomilies were outlined in the survey and 32 vertical diamond drill holes totaling 8,232 were put down on the two main anaomalies called the "A" and "G" zones. About four million tons of ore averaging 4.1% graphite was were outlined. No further drilling has been done since the publishing of this report although only a relatively small portion of the anomilies has been explored. ( National Graphite Corp -- OTCBB / NGRC is currently preparing a PLAN OF ACTION to further explore and extend the previous findings). The drilled area of the "G" zone is estimated to to contain 3.5 million tons of averaging 4% graphite and the "A" zone is estimated to contain 630,000 tons of 4.72% graphite. A considerable amount of lower grade material was also outlined in the drill program.
The Graphite is disseminated in a flat lying zone of biotite-feldspas paragneiss interbedded with crysatilline limestone areas and injected with pegmatite stringers. The ore bearing layer averages 77 feet thick in zone "G", and 61 feet in Zone "A". The graphite generally occurs in flakes throughout the zone and these appear tough with some of good size. The origin of the mineral is not clearly known and neither are the relationship to pegmatite stringers and injections.
A series of metallurgical tests have been completed on the ore and the graphite recovery was good according to the company officials. (Exact figures were not distributed as they were considered propriety and restricted from public distribution)
National Graphite Corp Board of Directors is discussing plans for construction of a 1000 ton plant which would begin as soon as talks with potential production outlets can be completed.
