Griffin Mining Limited ("Griffin" or "the Company") is
delighted to announce continued excellent results from
underground diamond drilling at its Caijiaying mine in
northern China. The Company conducted a comprehensive
program of diamond drilling comprising 190 underground
drill holes for 30,244 metres. None of these assays were
obtained in time to be included in the announced JORC
Resource of the 22nd May 2012. The major results of the
drilling program have been summarised in the attached
Appendix.
Better gold assays included:
-
37.4 metres @ 6.55 g/t gold & 4.33% zinc
-
35.0 metres @ 5.23 g/t gold & 4.47% zinc
-
28.5 metres @ 3.42 g/t gold & 1.92% zinc
-
13.00 metres @ 7.31 g/t gold & 3.45% zinc

-
4.05 metres @ 6.09 g/t gold & 11.48% zinc
-
4.00 metres @ 20.13 g/t gold & 7.38% zinc

-
26.40 metres @ 6.81% zinc
-

-
24.90 metres @ 7.50% zinc
-
20.30 metres @ 7.54% zinc
-
17.30 metres @ 9.22% zinc
-
16.40 metres @ 11.04% zinc
-
16.30 metres @ 13.32% zinc & 3.32 g/t gold
-
14.55 metres @ 9.32% zinc & 2.16g/t gold
-
11.00 metres @ 10.21% zinc
High-grade gold mineralization was identified in
underground extensions of the Ju Long, Fu Long, Xiao Long
and Qing Long ore bodies. In addition to the high-grade
gold intersections, Griffin continues to intersect
high-grade zinc zones within a wider envelope of
medium-grade zinc-gold-lead-silver ore. Drilling will
continue during 2012 to further delineate and evaluate the
highly prospective corridor of mineralization.
The discovery of this new high-grade gold, zinc, lead and
silver mineralization within the Caijiaying ore body can be
expected to make a significant and increasing contribution
to mine revenue
Chairman's Statement
Chairman Mladen Ninkov commented, "Even after the
production of an exceptional new JORC resource, further new
drill results exemplify the ever increasing size of this
world class, polymetallic, orebody. The enduring faith of
the Company's shareholders continues to be repaid in
abundance. I could not be more delighted for our
shareholders."
