MONTREAL, QUEBEC (FRANKFURT: EWX) is pleased to announce that
new mineralization has been intersected in DDH CM07-2030, a scissor
hole collared 135 metres south of previously reported DDH
CM07-2008, where significant mineralization was intersected in an
extension to the South Barnat Zone (see October 23, 2007 press
release). The new hole (DDH CM07-2030) intersected 1.89 g/t Au over
111.2 metres. It was inclined 50 degrees to the north towards DDH
CM07-2008 (which was inclined 45 degrees to the south), along the
same section. The table below outlines detailed intercepts from
both holes:

(i) previously reported
These two holes define a vertical cross-section in which
mineralization is located to the north and south of the old Barnat
and East Malartic mine workings, largely along the southern edge of
the Cadillac fault. The gold mineralization is hosted both in
silicified greywackes of the Pontiac Group south of the fault
contact and in schistose, carbonated ultramafic rocks and porphyry
dykes to the north of the fault contact. The mineralized section
defined by these holes occurs along the southeastern strike
extension of the South Barnat Zone (initially drill defined by
Osisko in 2006 with a series of 5 holes over a strike length of 230
metres). The new drill intersections and further compilation of
historical data suggest a true mineralized width of approximately
100 metres along this new extension, and the current minimum strike
length of the South Barnat Zone is now 600 metres. Gold
mineralization in the South Barnat Zone remains open at depth and
to the east along the north and south walls of the past-producing
East Malartic mine.
The South Barnat Zone is a separate mineralized zone located
approximately 1200 metres northeast of the center of the Canadian
Malartic deposit. These significant new results have prompted
Osisko management to initiate a definition drill program along the
South Barnat zone on 25 metre section spacings. Detailed design of
the program and void modeling of the South Barnat, as well as
portion of the East Malartic mine workings, will begin immediately.
The new program is estimated to comprise a minimum of 50,000 metres
of core drilling.
All NQ core assays reported above were obtained by standard 50 g
fire assaying-AA finish at ALS Chemex laboratories in Val d'Or,
Quebec. Reported weighted averages were calculated using a minimum
of 0.40 g/t Au over successive maximum intervals of 20 metres with
no upper cut-off of individual assays.
Osisko Exploration Ltd. is currently evaluating the Canadian
Malartic gold deposit and adjacent areas for a large-scale open
pit, bulk-tonnage mining operation. The Company is well-funded with
approximately $180 million on hand and is carrying out an
aggressive definition drilling and exploration campaign. An updated
NI 43-101 compliant, inferred gold resource estimate on the main
Canadian Malartic deposit was released on July 5, 2007 and the full
report is available on SEDAR.
Mr. Robert Wares, P. Geo. and Executive Vice-President of
Osisko, is the Qualified Person responsible for the technical
information reported in this news release.
