MORE HIGH GRADE COPPER AT MT LIDSTER
• Drilling at Mt Lidster in December 2006 has intersected further high grade
copper mineralisation;
• Best result was in MLRC09: 18m @ 2.4% Cu, including 2m @ 9.8% Cu.
• Highest single assay result: 1m @ 15.05% Cu and 1.04g/t Au;
• True widths of mineralisation up to 12m.
Malachite Resources NL (ASX: MAR) advises that assay results
have now been received for samples from December 2006 drilling at
the Mt Lidster Copper Project, near Mt Isa in northwest Queensland,
where Malachite has an option to acquire a 100% interest. The best
intersection in the recent drilling was in hole MLRC09, which cut an
18m massive sulphide zone from 76m to 94m (11.6m true width),
with an average grade of 2.4% Cu, including 2m of 9.8% Cu.
Several holes intersected massive to semi-massive sulphide
mineralisation, with good copper values, mainly expressed as
primary chalcopyrite. Other holes intersected the structure where it
is dominated by quartz rather than sulphide. Copper grades
correlate well with sulphide content and it is apparent from both
drilling to date and inspection of the outcrop that mineralisation is
concentrated into pods or shoots within the Mt Lidster structure, at
least near surface. Copper mineralisation was also intersected in
what appear to be parallel or splay structures, some examples of which can be seen at the
surface. Significant amounts of gold and cobalt are present as accessory metals.
Twelve shallow, reverse circulation percussion holes were drilled in the latest program, for a
total of 959m. Drill hole details are set out in Table 1 and assays of the mineralised
intersections are listed in Table 2. The map below shows the Mt Lidster structure and the
location of all holes drilled at the project to date.
Malachite is strongly encouraged by these results, for while the drill sample assays to date are
mixed, it is clear that this is due to the poddy distribution of mineralisation within the structure.
Where good mineralisation is intersected the grades can be spectacular – the best single
assay from the recent program was 1m @ 15.05% Cu and 1.04g/t Au. Much of the structure
remains to be drill tested and as yet there has been no deep drilling at Mt Lidster at all. It is
too soon to draw any conclusions about average grades within the Mt Lidster structure overall,
but it is possible that, in a future mining context, the high grade massive sulphide pods may be
sufficiently abundant to carry the interspersed lower grade quartz-rich zones. It is also
possible that the massive sulphide zones will expand or coalesce at depth, where drilling is yet
to occur.
Following the current tropical wet season the Company plans to conduct a geophysical
survey, utilising an electromagnetic (“EM”) technique, at Mt Lidster, with the aim of identifying
electrical conductors that could represent the best concentrations of massive sulphide
mineralisation at depth. These will then be targeted by drilling, including diamond drilling if
warranted, during the 2007 field season.
