Caijiaying Regional Exploration Program
Reverse Circulation Drill Results
Griffin Mining Limited ('Griffin' or the 'Company') is pleased to announce the
results of its 2005 regional exploration program of areas surrounding the
Caijiaying Mine (the 'mine') in northern China.
Zone II (East)
A new zinc target was discovered at Zone II (East), 1,200 metres from Zone III
where the mine is in operation, by an IP geophysical survey completed by Griffin
in 2004. Drill testing of this target has resulted in a new discovery which
yielded RC drill intersections of:
52 metres @ 5.45% zinc from 72 metres depth, including
12 metres @ 12.35% from 72 metres plus 4 metres @ 7.61% zinc from 92 metres
A second hole of a similar orientation yielded:
12 metres @ 5.82% zinc, including
8 metres @ 9.82% zinc and
8 metres @ 116 g/t silver.
Further work will be undertaken this year to ascertain the orientation of this
mineralisation.
Zone II (Central)
The main part of Zone II, 200 metres to the west of Zone II (East) has also been
confirmed as a precious metals prospect with significant gold and silver
intersections of:
10 metres @ 2.21 g/t gold and
8 metres @ 228 g/t silver from 171 metres.
This suggests much more precious metal enhancement than was obvious from
previous work.
The zinc intersections from this zone are mainly in 4 metre composites and are
in line with the previous Chinese results including:
4 metres @ 9.23% zinc from 116 metres;
4 metres @ 8.16% zinc from 116 metres; and
8 metres @ 5.06% zinc from 120 metres including 4 metres at 8.96% zinc
4 metres @ 5.89% zinc from 132 metres
Significantly, it was not possible to test the 1 kilometre long area between
Zone II and the mine at Zone III due to newly planted flora. A long lead time
is required for forestry permitting and land clearance to drill in this area.
This should be obtained by the spring, ready for further follow-up drilling in
the summer.
F45 Fault
The primary target of the major F45 Fault zone, 1 to 1.3 kilometres south of the
mine, has been confirmed with significant gold intercepts recorded in two holes
900 metres apart at about 150 metres depth. The two intersections recorded
were:
4 metres @ 3.96 g/t gold; and
3 metres @ 4.24 g/t gold.
As both of the positive results are from a similar depth and quite far apart,
they indicate the level of gold precipitation in this target is similar to the
level where gold is currently being proved in the mine by the ongoing
underground drilling program. Defining the level of gold precipitation is an
important step in targeting epithermal gold deposits and was a major aim of the
survey.
As gold results continue to emerge from the mine underground drilling program,
the geometry and nature of the gold mineralisation is becoming clearer and this
knowledge is expected to impact favorably on the ongoing gold exploration
program in the region.
Conclusion
The conclusions from the summers drilling program are preliminary as it will
take considerable further study to fully evaluate the large amount of data now
to hand.
Mladen Ninkov, Griffin's Chairman, commented on these developments as follows:
'Although it is unfortunate that the results from the reverse-circulation
drilling programme, which was completed in October 2005, were substantially
delayed due to the extraordinarily slow delivery of results from the assaying
laboratory, it has been worth the wait. Caijiaying continues to fulfill
expectations with the continuing discovery of further mineralisation which has
every possibility of developing into economic ore capable of being processed
through the existing plant at Caijiaying. This is another positive result for
the shareholders of the Company.'
