Excellent New Drilling Results Post New JORC Resource

24th May 2012

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 22^nd 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

11.0 metres @ 8.98 g/t gold & 12.63% zinc

9.50 metres @ 7.53 g/t gold & 6.65% zinc

8.45 metres @ 6.85 g/t gold & 7.89% zinc

7.05 metres @ 7.81 g/t gold & 5.74% zinc

7.05 metres @ 7.08 g/t gold & 6.26% zinc

6.50 metres @ 5.38 g/t gold & 3.24% zinc

6.05 metres @ 4.16 g/t gold & 7.81% zinc

5.85 metres @ 6.38 g/t gold & 8.76% zinc

5.60 metres @ 11.90 g/t gold & 9.66% zinc

4.95 metres @ 8.98 g/t gold

4.30 metres @ 9.57 g/t gold & 2.70% zinc

4.05 metres @ 6.09 g/t gold & 11.48% zinc

4.00 metres @ 20.13 g/t gold & 7.38% zinc

Better zinc assays included:

25.40 metres @ 15.50% zinc

30.00 metres @ 10.91% zinc

26.40 metres @ 6.81% zinc

26.20 metres @ 8.47% zinc & 3.74 g/t gold

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."
