    New High Grade Vein Discovery
             



1 December 2008

                        MEDUSA MINING LIMITED
                             (AIM: MML)

                 MAJOR NEW HIGH GRADE VEIN DISCOVERY

Medusa Mining Limited ("Medusa" or the "Company"), the Australian
based company operating and developing gold mines in the Philippines
through its Philippines operating company Philsaga Mining Corporation
("Philsaga"), announces that it has discovered a new high grade vein
at the Co-O Gold Mine, named the Great Hamish Vein ("GHV"). The GHV
is currently interpreted to be between 600 to 650 metres long and
open along strike and at depth. Development on two levels has
commenced.

The GHV drill hole intersections to date are:

Geoff Davis, Managing Director of Medusa, commented:

"These spectacular results from the 12 drill holes, into the GHV,
average very close to two ounces of gold to the tonne, and are
strongly supported by the development already underway.  These again
demonstrate the excellent potential of the Co-O Mine vein system
which Management believes will continue to deliver more discoveries
as we carry out further drilling".

Discussion

Figure 1 shows the location of the Co-O Mine and Figure 2 shows all
the diamond drill holes from MD 85 upwards drilled and in progress
around the Co-O Mine and the projection of the vein system. Figure 3
shows the longitudinal projection of the GHV and Figure 4 shows the
current three dimensional model of the Co-O vein system excluding the
GHV. Please see the link at the end of this announcement for these
images.


Description

The GHV has been  defined over approximately 550  metres on the  west
side  of  the  Oriental  Fault  and  is  interpreted  to  have   been
intersected on the east side  of the fault in  holes MD 87,  98,  108
and 112 over a  strike length of approximately  100 metres. The  vein
has consistent  high  grades  and generally  dips  northwards  around
60-70º.

It has been intersected by drives on Levels 2 (50 metres below  adit)
and 3 (100  metres below adit),  with driving on  vein and  sub-level
development commenced.

Assays from the levels to date are:


+-------------------------------------------------------------------+

|         |             | metres at 39.79 g/t gold                  |

|         | Sub-level   | 133 metres length at average width of 1.2 |
|         |             | metres at 33.72 g/t gold                  |

|---------+-------------+-------------------------------------------|
| Level 3 | Level drive | 87 metres length at average width of  1.2 |
|         |             | metres at 92.00 g/t gold                  |
|---------+-------------+-------------------------------------------|
|         | Sub-level   | 82 metres length at average width of  1.0 |
|         |             | metres at 70.09 g/t gold                  |

Drill results

Table I lists the surface diamond drilling results greater than 3 g/t
gold from the Co-O  Mine for drill holes  which have intersected  the
GHV from MD  85 onwards. Some  intersections in MDs  85-88 have  been
previously reported on 11  August 2008. Other previous  announcements
on the Co-O drilling on 9 July,  15 May and 28 February 2007  contain
information regarding drilling and surveying techniques, comments  on
vein interpretation and methodologies and assaying protocols.

Drilling  with  four  surface  rigs  and  two  underground  rigs   is
continuing.
