                         OF CAIJIAYING PROCESSING PLANT


Griffin Mining Limited ('Griffin or the 'Company') is extraordinarily pleased to
announce that dry commissioning of the Caijiaying processing plant has been
successfully completed and wet commissioning has commenced with initial
production of zinc concentrate expected in mid June.



Mladen Ninkov, Griffin's Chairman, commented on these developments as follows:


'The Company has fulfilled its promise to its shareholders and the market by
commissioning, what the Company believes, is the first new foreign owned and
operated mine to be constructed in the Peoples Republic of China in the modern
era.  This was achieved on time and on budget.  The scale of this achievement
cannot be exaggerated.  I congratulate all those who contributed to this
outstanding success including the long term shareholders, financial advisors,
consultants, contractors, government authorities, management and the directors.'
