Les Mines J.A.G. Ltee ("JAG")(TSX VENTURE: JML) presents and update
on the ongoing exploration works, since the spring 2011 on its
St-Robert Property, located close to the village of
St-Robert-Bellarmin, some 40 km west of Lake Megantic in the
Appalachian region of Quebec.
The 100% JAG owned St-Robert property hosts many quartz veins
and carbonates rich in poly-metallic sulfides (Pb, Zn, Ag, Cu, W,
Sb, Mo, Au) injected in the sedimentary rock of the Compton
Formation of the St-Francois Group. Drill holes completed by JAG
during the 1980's showed that the veins are associated with the
creation of an important intrusive system of felsic porphyries and
Mafic dykes. Mineralized showings of pyrite (Py), scheelite (W),
molybdenite (Mo), stibine (Sb) and chalcopyrite (Cu) are exposed in
the Lee tunnel located in the Northern section of the property,
while pyritic galena and scheelite showings surface in the Lacombe
tunnel found in the middle of the property and quartz veins rich in
sphalerite (Zn), argentiferous galena (Pb-Ag), pyrite and cosalite
were identified in the Southern portion of the property.
During the fall of 2010, JAG initiated a compilation of
exploration work and small scale production done between 1951 and
1958 by St-Robert Metals Corporation, by Nouvelle Mining between
1972 and 1976 and between 1977 and 1984 by JAG itself. The
geological and geophysical surface data has been digitalized and
GIS integrated. The electrical resistivity Induced Polarization and
seismic refraction data was also reprocessed and digitalized to
evaluate the variability of these parameters in relationship to the
depth and probable presence of intrusive associated mineralization.
In this manner it was shown that the chargeability data tends to
increase with Dipole (N=1 to N=6) spacing which suggests that the
proportion of vein disseminated sulfides tend to increase at depth
as they approach the prophyry intrusive. New maps combining
historical geochemistry and geophysical data were also produced and
suggest the presence of a 500 meter long anomalous zone rich in Pb,
Ag, W and Mo, located immediately to the West of the Lacombe
Tunnel. These maps will help in better delineating the zones which
will be subject to more detailed exploration efforts.
In the spring of 2011 a high resolution gravity survey was
completed on the property. Combined with MAG data the new gravity
information permitted to better locate the contact between the
intrusive and sedimentary rocks and to determine their thickness
above the intrusive system.
A team lead by the geologist, Dr. Marc Richer-LaFleche, Ph. D.
of the INRS, is currently performing several surface geophysical
surveys including audiomagnetotellurics, geoelectrical tomographic
and Promis-10 electromagnetic frequential surveys. It will also
complete the systematic sampling of the mineralized zones and
prepare and analyze densitometry concentrates. Drilling is expected
during the winter of 2011-2012.
