The Hebecourt
property straddles the
boundary between the Quebec and Ontario
provinces. The property is 100% owned by
Cogitore, subject to a
50% back in right held by Inmet Mining Corporation, and is accessible
via public and logging roads which run across
the
project area.
It is
underlain by volcanic rocks that
are at the base of the prolific Blake River Group of the Abitibi
Subprovince
and is also located about 4 km
south of the regional Destor-Porcupine Break which controls many world
class gold
deposits, including the Timmins gold camp. The core of the
Hébécourt property
is marked by a 200-300m thick rhyolite unit that is found across the
center of
the property. Recent age dating done by the Government shows that the
Hebecourt
rhyolites are of the same age as those hosting the world class Horne
mine in
Rouyn-Noranda (54 Million tonnes produced at a grade of 2.2% copper and
6.1 g/t
gold). The Hebecourt rhyolite is locally weakly to strongly altered to
sericite
and chlorite with local carbonate. The property encloses a series of
VMS-style
zinc and copper showings that are found mostly in felsic rocks but also
locally
in mafic flows. Previous work has been focused mostly on footwall-type
stringer
mineralization but no systematic exploration has targeted the top of
the
felsics where massive sulphides are more likely to occur. Several
cherty
horizons mineralized with pyrite and carrying anomalous copper and zinc
values
have been identified near the top of the felsics and also within mafic
rocks,
indicating the presence of promising hydrothermal systems.
Cogitore
has drilled about a dozen
holes specifically targeting the top of the Hebecourt rhyolite unit and
associated conductors. Encouraging mineralization was obtained in hole
HEB-02
which yielded 1.2% Zn over 7.2 metres, including 3.58%Zn over 1.0 metre. The
mineralization in HEB-02 consists of "classic" stringer-style
mineralization with chlorite alteration such as is typically found
around VMS
deposits. In the east sector of the property, hole HEB-05 intersected
1.1% zinc
and 599 ppm copper over 9.7 metres. Finally, at the west end
of the property drill
hole MD-03 intersected a narrow quartz vein enclosing a 10 cm massive
sphalerite pod and
which assayed 21.0% zinc and 0.95% copper over 25 centimetres.
This
vein may represent remobilization of metals from a nearby massive
sulphide
lens. Research work is currently in progress in cooperation with
government and
university research teams with the objective of better understanding
the
volcanic environment in order to define future drilling targets.
