  GRIFFIN ANNOUNCES 'DRY COMMISSIONING' DATE FOR CAIJIAYING OF 25TH APRIL 2005


Griffin Mining Limited ('Griffin or the 'Company') is extremely pleased to
announce that its Chinese design and engineering consultants and construction
managers for the Caijiaying mine and processing plant, the Beijing Engineering
Non-Ferrous Institute ('ENFI'), have confirmed that, subject to the delivery and
installation of a small number of remaining components, the planned date of dry
commissioning of the Caijiaying plant will be Monday, the 25th of April, 2005.
This is on schedule and within the planned ENFI budget.


Assuming dry commissioning encounters no installation or manufacturing defects,
production should commence immediately after the curing of the main plant floor
on the 15th of May 2005. In anticipation of commissioning, zinc ore has already
been mined and stockpiled at the surface ready for processing.


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


'Rarely does a dream become reality.  Caijiaying remains on track to be
commissioned on time and on budget in an extremely strong zinc metal market.  It
is a just reward for the courage, patience and support the shareholders have
shown for the Company.  I could not be more delighted.'
