Big North Graphite to Commence Exploration Program on Lyndoch - Griffith and
Brougham Graphite Properties, Ontario and Commissions NI 43-101 Technical Report
Vancouver, B.C., May 2, 2012 – BIG NORTH GRAPHITE CORP. (TSX-V: NRT) (the “Company” or
“Big North”), is pleased to announce that further to its press release dated April 19, 2012, the
Company has commenced an exploration program on the approximately 6,500 hectare Lyndoch -
Griffith and Brougham properties, located in southern Ontario. Exploration is to commence on the
properties with a helicopter airborne EM survey flown at 100m line-spacing.
Independent geological consultants G.A. Harron and Associates of Toronto have been commissioned
to write a National Instrument 43-101 report on the property and have completed their site visits. The
report will include the results of the airborne survey work, compilations of all known geology and past
work, and will make recommendations for detailed surface follow-up work for early summer.
Both blocks cover substantial tracts of graphite-prospective Grenville-age marble+/- gneiss geology
and are unexplored, in terms of modern technology, for graphite. Both encompass historic graphite
occurrences. Government assessment files (1982) indicate a graphite occurrence in marble in the
Griffith Township portion of the Lyndoch - Griffith block (".... two foot wide vein bearing 10-20%
graphite occurs in marble..."). The Brougham block is anchored by two historic graphite occurrences
in the Southeast, which may be the extension of the drill-proven Coronation graphite zone on the
nearby Black Donald property of Standard Graphite Corporation.
The historic Black Donald Mine was located to the south of the present Big North Brougham block on
the south side of Black Donald Lake. This marble-hosted deposit was an extremely high grade mine
which dominated Canadian graphite production during its operational lifetime (1896-1954). During the
last 10 years of mine life the average reported grade was 25 to 30 per cent graphitic carbon ("Cg").
About 94 per cent of the total value of Ontario graphite production came from the Black Donald Mine.
There is currently a considerable amount of graphite activity in the Grenville geologic province of
southern Ontario. The Grenville Province is characterized by a suite of Precambrian-age, high
metamorphic grade rocks that by virtue of their initial carbon-bearing composition and subsequent
metamorphic and deformation history, are prospective for economic graphite deposits, particularly of
the coarse flake variety. The two most advanced projects in the region are those of Northern Graphite
Corporation at their Bissett Creek deposit and Ontario Graphite at their Kearney Deposit.
The Lyndoch - Griffith and Brougham properties consist of two approximately equal-size claim blocks
in Lyndoch-Griffith and Brougham Townships and are located about 140 kilometres south of Ottawa.
The properties contain or adjoin numerous historical graphite occurrences. The Property is located in
an area of well-established access and infrastructure.
Maps of the properties are posted in the corporate presentation on the company’s website at:

2. Big North Graphite is also pleased to announce that MPH Consulting Limited of Toronto will be
primarily responsible for the exploration programs at Big North’s graphite properties in southern
Ontario.
Bill Brereton, P.Eng, a qualified person as defined by National Instrument 43-101, and independent of
