Sankarani Project, Mali - Exploration Update



Glencar is pleased to announce the results of recent sampling in an exciting
mineralised zone near Komana, within the Sankarani Project area in Mali, which
comprises a total area of approximately 1,000 square kilometres.  The
mineralisation occurs in a highly sheared zone, with active and intensive
associated artisanal activity over a strike length of more than 1 kilometre.
Eighteen samples collected by Glencar from artisanal pits, excavated to depths
of more than 30 metres, yielded an average gold grade of 5.68 grams/tonne. The
gold occurs within a highly sheared suite of metasedimentary rocks including
graphitic schists. The presence of quartz does not appear to be a prerequisite
for gold development.  Within the 1 kilometre strike length already defined,
there are igneous bodies which have been intruded into this package of
metasedimentary rocks.  Our initial investigations have shown that gold is also
found within these intrusive rocks and work is currently underway to establish
the nature of such mineralisation and whether it is associated exclusively with
quartz vein development or whether there is more widespread gold mineralisation
within the intrusive.  Work is continuing to ascertain the potential strike
length of this exciting target prior to drilling.





Background



Glencar holds an interest in four exploration concessions in southern Mali.  The
area is underlain by rocks of the Birimian system, the prolific host rock for
most of the world class deposits of West Africa, such as Morila in Mali and
Obuasi, (Ashanti) in Ghana.  Glencar has carried out detailed structural/
geological mapping, geochemical surveys and reinterpretation of the results of
the airborne magnetic survey flown by the Government of Mali.  The results of
this work have led to the selection of four first-priority targets, of which
Komana is one, which will be drilled during the current year. Further details
about the Komana target and the other delineated targets will be made known in
due course.   It is likely that, with further detailed exploration and
interpretative work, additional drill targets will be defined within the project
area.



The targets which will be drilled have been selected based on their prospective
geological/structural features, strongly anomalous geochemistry and often
associated active artisanal workings, indicating the presence of gold.  A follow
up  programme of detailed mapping and sampling is being carried out and it is
possible that, prior to the commencement of drilling, detailed geophysical,
ground magnetic surveys will be carried out to enable better definition of the
drill targets and more efficient utilisation of the drilling budget.
