              LINGIG COPPER DISCOVERY DRILLING RESULTS 
 
Medusa Mining Limited ("Medusa" or the "Company"), through its 
Philippines subsidiary, Philsaga Mining Corporation ("Philsaga"), 
announces the first summary of available diamond drilling results 
from the Lingig Copper Discovery. 
 
Selected available intersections (at 0.1% copper cut-off) include:

The mineralisation drilled to date is hosted within a 200 to 300 
metre thick thrust fault which is interpreted to be linked to a 2km 
by 1.5km intensely silica and clay altered, stockworked and 
brecciated quartz dacite intrusive complex that is located 
approximately 1,200 metres to the south. Some of the deeper creek 
exposures within this complex exhibit copper sulphide mineralisation. 
 
Assaying of selected mineralised drillhole material indicates that 
the copper mineralisation does not contain detectable levels of 
deleterious elements. 
 
Whilst it is very early in the exploration programme, the Company 
believes, based on evolving geological interpretations, that this is 
potentially a large mineralised copper system. 
 
 
GEOLOGICAL SETTING 
 
Figure 1 (please see the link at the end of this announcement) shows 
the current interpretation of the regional geology and Table 1 
contains drill hole results to date.  Figure 2 (please see the link 
at the end of this announcement) shows a longitudinal projection of 
the drilling completed to date and the relevant historical drill 
holes. 
 
Comparison with the Atlas Mine on Cebu Island shows there may be some 
similarities with the structural setting and styles of 
mineralisation. At Atlas, mineralisation is hosted predominantly in 
intrusive porphyry rocks at the Biga Barot and Carmen deposits, and 
predominantly in volcanic rocks (and associated with some intrusive 
and mineralised porphyry sills or dykes) at the Lutopan deposit where 
mineralisation is 120 metres thick and 900 metres long. The Biga and 
Carmen deposits are located between two steeply dipping regional 
scale faults (Bureau of Mines and Geosciences, 1986). 
 
The Atlas deposits, including mined material, have total resources of 
1.53 billion tonnes at 0.41% copper and 0.24 g/t gold 
(www.atlasphilippines.com). 
 
 
 
 
Mineralised Thrust Zone 
 
Since commencing drilling in June 2008, the Company has completed 
approximately 4,000 metres in 8 holes (angle and vertical) using one 
drilling rig. Drilling difficulties were experienced in several holes 
which led to the premature abandoning of LIN 1 and LIN 4 drillholes. 
LIN 4, which was twinned by LIN 5, has not as yet been assayed. LIN 8 
has just been completed and assays are awaited. 
 
The mineralisation discovered by a 1974 aid programme in drill hole 
DDH 1 (the five DDH aid programme holes are now relabelled as JDH 1 
to JDH 5, see the announcement dated 13 November 2007 and the 
December 2007 quarterly report for detailed descriptions) has now 
been shown to be contained within an extensive east dipping 200 to 
300 metre thick thrust zone. The thrust footwall is an unmineralised 
quartz diorite which intruded the basaltic sequence (numerous basalt 
xenoliths are present near the diorite contact). The intrusive 
contact appears to have subsequently become the footwall of the 
regional thrust zone. Plate 1 (please see the link at the end of this 
announcement) shows the outcropping thrust contact. 
 
The mineralised porphyry intersected in the bottom of the discovery 
hole JDH 1 (and subsequently in several new holes) appears to be a 
north-plunging or dipping partly mineralised porphyry sill up to 
approximately 100 metres thick within the thrust zone. Some chilling 
has been noted in places on its contacts. This porphyry sill has also 
been found as a west-trending 60 metre long copper mineralised 
outcrop approximately 200 metres southeast of holes LIN 2 and LIN 3. 
Its full extent, role in mineralisation and degree of mineralisation 
are not yet understood. 
 
Within the thrust zone, and to a lesser extent above the thrust, 
there is widespread epidote alteration as epidote veins, epidote 
quartz-sulphide veins and disseminated epidote clots and disseminated 
grains. To date the epidote alteration has been ubiquitous in the 
area drilled. Magnetite as disseminations and veins is generally 
closely associated with the copper mineralisation. 
 
Sulphide mineralisation within the copper mineralised zone comprises 
fairly ubiquitous pyrite up to 10% and lesser copper sulphides 
predominantly as chalcopyrite with some chalcocite and minor bornite, 
particularly in holes LIN 2 and LIN 3. 
 
Assaying of selected samples from hole LIN 6 indicates that the 
mineralising system is clean and does not contain arsenic, mercury or 
antimony above detection limits. 
 
Roadways approximately 200 to 300 metres south of LIN 2 and LIN 3 
have exposed intensely sulphide (now limonite) veined and 
stockworked, argillically weathered basalt indicating that the 
mineralisation is likely to extend beyond these outcrops to the 
south. 
 
The footwall of the thrust fault is interpreted to extend southwards 
at least as far as the quartz dacite intrusive complex. 
Mineralisation, possibly within or related to the thrust, located 
approximately 1,500 metres south of the current drilling was 
intersected by previous drill holes JDH 3 and 5 (Table 1). 
Mineralisation controls and trends within the thrust are expected to 
become clearer as drilling progresses over the coming months. 
 
Quartz Dacite Porphyry Intrusive Complex 
 
The extensive quartz dacite intrusive complex to the south of the 
current drilling covers an area of approximately 2km by 1.5km. In 
1996-97 Barrick Gold (Phils) Inc. undertook extensive sampling of 
outcropping altered material targeting bulk gold mineralisation. An 
old report indicates that 16 outcrop samples returned gold values in 
the range from 0.2 to 1.5 g/t gold; however detailed sample location 
maps are not available. 
 
Large areas of the complex are brecciated and commonly silicified and 
quartz vein stockworked. Many of the silicified rocks are cut by late 
fine quartz veining. Sulphides (now limonite) generally comprise 1 to 
5% of the silicified rock. Argillic alteration is also present in 
some areas. 
 
Other areas of sulphidic milled breccias with approximately 30 to 50% 
milled fragments in a 50 to 70% limonite matrix have been observed. 
 
Some deeper creek exposures show common chalcopyrite and lesser 
covellite. 
 
A comprehensive programme of outcrop sampling, and in some areas, 
soil sampling is in progress. 
 
Work Programme 
 
One drilling rig will continue working along the thrust zone and has 
commenced LIN 9 to the south of LIN 2 and 3, and will then work its 
way southwards. 
 
It is intended, later in the year, that a second drilling rig will be 
added to commence drilling the large potential porphyry copper 
target. 
 
 
Geoff Davis, Managing Director commented: 
 
"These initial results confirm and enhance those of the original 1974 
discovery hole.  Whilst it is very early in the exploration 
programme, the Company believes that this is potentially a large 
mineralised copper system.  As confidence in the geological model 
increases we plan to add additional drill rigs to speed up the 
defining of a potential resource."
