Note:
(1) Gold production is actual gold produced during the period and does not
reflect changes in the balance of gold in circuit;
(2) Cash costs refer to the cost of gold mined (net of mine development
costs), produced and sold and includes taxes, royalties and local
production taxes of US$48 per ounce for the Dec 2009 qtr (Dec 2009 half-year of
US$46 per oz).
Gold production for the quarter increased to 21,108 ounces (a 17% increase from
the previous quarter's production) at an average grade of 18.68 g/t gold and
cash costs of US$184 per ounce.
Medusa is an unhedged gold producer and received an average gold price of
US$1,111 per ounce from the sale of 21,108 ounces of gold for the quarter.
Phase II of the Company's expansion programme is on schedule, and the
incremental benefits of that expansion are flowing through as evidenced by the
record gold production of 39,162ounces for the past six months. The forecast
gold production for the fiscal year to 30 June 2010 has been revised upwards
from 86,000 ounces to 89,000 ounces at an anticipated average cash cost of
US$190 per ounce.
As described in the announcement dated 16 May 2007 regarding the occurrence of
"black leader" high grade mineralisation in some veins, there has been an
unusual amount of black leader material in recent mine development activities
which is responsible for the current high grades. The occurrence of black leader
material rarely shows up in drilling and at this stage, its occurrence is not
predictable.
A breakdown of actual and forecasted production ounces and cost per ounce by
quarters for the last six quarters and the remaining two quarters of this fiscal
year is highlighted in Graph 1 (please see the link at the end of this
announcement).
PHASE II EXPANSION
a. Mine Production
The mine can now produce at the required rate of approximately 750 tonnes of ore
per day to achieve a production rate of approximately 100,000 ounces annualised.
The vertical Ventilation Shaft near the Baguio Shaft is now being fitted with a
skip and headframe to haul mineralised material as sufficient mineralised
material has now been located above Level 1.
b. Mill Expansion
The new mill crushing, screening and washing circuits were completed on
schedule. A new back-up genset due to arrive early December was delayed by the
Christmas period until the second week of January. Commissioning of the mill
expansion has commenced.
c. Tailings Dam
Construction of a new eight year life tailings dam is progressing and is due for
completion mid-year 2010 subject to favourable weather conditions.
d. Power
The Company has been evaluating several options to replace the rural power line
currently in use from San Francisco to the mill site with a dedicated power
line, as the current rural line is becoming unreliable due to the increase in
load. The favoured option (in agreement with the local power co-operative) will
involve the installation of a new power line along the same route as the current
power line and the cost of the capital outlay by the Company will be offset by a
reduction in future power tariffs.
RE-INTERPRETATION OF RESOURCE MODEL
The sole purpose of the re-interpretation was to correct inconsistencies to the
east of the Oriental Fault between previous drillhole based interpretations and
the on-going development on Level 5 from the Agsao Shaft. The revised resource
is JORC and NI 43-101 compliant. A large number of drill hole intersections are
yet be included in the re-interpreted resource model (Fig.3please see the link
at the end of this announcement).

The resource estimations have been undertaken by Cube Consulting Pty Ltd, 2010.
Note: Rounding may result in some slight discrepancies in totals
This re-interpretation has marginally decreased the Inferred Resources but
maintained the Indicated Resources taking into account production of 39,162
ounces and stockpiles containing approximately 8,500 ounces. This now provides
an accurate development based model for expanding the mine to the east.
Thirty-five veins have now been modelled with resources and more are expected to
be identified. Future resource updates will be done annually in June-July.
Discussion
Diamond drilling has continued since the resource model update announced on 1
July 2009 and focused on extending the Co-O vein system. A total of 52 drill
holes have been completed (as announced on 10 December 2009) since the previous
resource estimation and considered for inclusion in the re-interpreted resource
model in conjunction with available underground sampling data, and excluding
mined material.
Thirty five veins now have resources allocated to them, with a number of the new
veins, particularly the East Agsao series of veins, being open in almost all
directions. The vein system is open at depth.
It should be noted that a large number of drill holes in a number of areas shown
on Figure 4(please see the link at the end of this announcement) are still to be
included in resource estimates, and will be included as the confidence levels
increase and demonstrated continuity improves through additional drilling and/or
development.
As a result of extensive development from the bottom of the Agsao Shaft (Level
5) since the previous resource estimate, this new wireframe model has corrected
previously noted (see announcement of 1 July 2009) inconsistent vein
orientations on the east side of the Oriental Fault. It is now clear from the
underground development that the vein system continues in an easterly direction,
disrupted in places by north-trending step-faulting, which generally down-throws
the veins on the east side of each fault. Re-interpretation as straight veins
has resulted in some inferred resources loss compared to the previous
interpretation of curved veins which was based solely on drillhole data.
Figure 5(please see the link at the end of this announcement) shows all the
current development in the mine.
Resource drilling is continuing with the aim of increasing confidence levels for
interpretation in some areas which will result in the inclusion of more drill
hole intersections as well as extensions to the vein system.
Stockwork/stringer mineralisation
At the western end of the mine, preliminary work suggests the possible presence
of a number of stockwork or stringer zones where narrow quartz veins over widths
of 5 to 6 metres have been developed. One of these has been defined as
approximately 40 metres long within the Great Hamish Vein. An Alimak rise within
this zone has been completed between Levels 2 and 3 demonstrating continuity and
that it is open above and below these levels. Two early bulk samples tested
through the mill returned head grades of 14 and 17 g/t gold. Alimak long-hole
stoping (much cheaper than shrink stoping) is about to commence in this zone and
will be employed if other similar zones are defined.
Other potentially similar stockwork or stringer zones may be present in parts of
other veins and a similar zone outcrops near the Tinago Shaft which will be
subject to additional exploration. A drive to connect the Baguio Shaft and the
Tinago Shaft on Level 3 is underway and expected to allow underground assessment
of previous drill hole TIN 3 with a similar interpreted style adjacent to the
Central Vein and between Levels 2 and 3. It returned two close spaced
intersections of 3.80 metres at 21.15 g/t gold and 6.60 metres at 2.45 g/t gold
(see announcement dated 28 February 2007).
Specific gravity
A programme of specific gravity ("SG") measurements is underway for the lower
levels of the mine. Initial results indicate that the currently used SG of 2.45
may be conservative. This programme should be completed before the next resource
estimate.
Vein modelling
Cube Consulting Pty Ltd of Perth, Western Australia was contracted to undertake
the resource estimations. A wireframe model of the vein system and the mine
depletions were based on all available information as at 7 December 2009. A 2D
longitudinal modelling approach was used and is based on an accumulation
variable incorporating mineralised vein horizontal width and intercept grade.
Variography was used to analyse the spatial continuity of the horizontal width
and accumulation variables within the mineralised veins and to determine
appropriate estimation inputs to the interpolation process. The accumulation
variables were interpolated into blocks using Ordinary Kriging. High grade
limits were applied to gold prior to the calculation of the accumulation
variable. Mineral resources have been reported in accordance with The 2004
Australasian Code for Reporting of Mineral Resources and Ore Reserves (JORC
Code) and Canadian National Instrument 43-101.
RESOURCE DRILLING
On 10 December 2009 the drilling results for drill holes MD 165 to 216 were
released. These results are summarised in TableIII which should be read in
conjunction with the 10 December 2009 announcement which contains more detail
and intersections down to 0.2 metres downhole width.

Drilling is continuing along and across strike at the Co-O Mine using six
surface diamond drill rigs with the aim of increasing confidence levels in some
areas and identifying additional mineralisation that can be developed for
production.
Co-O MINE CONCEPTUAL TARGET SIZE **
Estimates (Table IV) have been undertaken for the Co-O Mine conceptual target
size** based on a drill-defined strike length of approximately 1,500 metres and
up to 2,000 metres based on potential extensions.
Aggregate across-strike widths of the veins of 5 and 8 metres (ie, adding the
width of each individual vein across strike to give an aggregate vein width) are
regarded as possibly conservative. Depths of between 500 and 750 metres below
Level 1 (adit level) in the mine are regarded as geologically reasonable as a
few deeper drill holes below 400 metres below Level 1 have intersected good
grade mineralisation.
The estimate used a grade range of 9 to 11 g/t gold with a preferred average
grade of the current resources of 10 g/t gold.

REGIONAL DRILLING
Up tothree surface rigs are testing new veins around the Co-O Mine as shown on
Figure 6 (please see the link at the end of this announcement). The aim of this
drilling is to extend the vein system so that additional production scenarios
can be considered through replicating mining infrastructure.
The Co-O vein system outcrops at surface on the western side of the Oriental
Fault, where it was first discovered. The veins at surface rarely exceed 0.5
metres width and generally assay around 1 to 5 g/t gold (with possibly some
supergene enrichment). Gold values started to increase significantly
approximately 80 metres below surface.
Up to the announcement on 9 December 2009, 16 drill holes (EXP 1 to 16) had been
completed. Results are available for EXP 1 to 12 (Table V) where strongly
anomalous values have been obtained from a number of individual samples in
excess of 0.5g/t gold and up to 5.13 g/t gold. These mineralised structures will
be assessed for further follow-up either along strike or at depth.

ABOUT MEDUSA MINING LIMITED
Medusa Mining Limited("Medusa" or the "Company"), a public company listed on the
ASX, AIM and the TSX, is an Australian based gold producer, focussed solely on
the Philippines.
With current mineral resources comprising Indicated 580,000 ounces of gold and
Inferred 1,310,000 ounces of gold, Medusa's corporate strategy is to become a
mid tier 300,000 to 400,000 ounce per year, low cost gold producer.
The Company is currently expanding its high grade Co-O Mine operations
(Indicated Resources 580,000 ounces of gold inclusive of a Probable Reserve of
500,000 ounces of gold, and Inferred Resources 660,000 ounces of gold) to
increase its forecast production to 100,000 ounces per year in 2010, and is
conducting near mine exploration to assess the possibilities of further
expansion to 200,000 ounces per year. Current cash costs at the Co-O Mine are
approximately US$200 per ounce.
A pipe-line of deposits is now being established with the Bananghilig Deposit
(Inferred Resource of 650,000 ounces of gold) recently added and which is
expected to expand, potentially in conjunction with nearby discoveries.
Further potential upside exists in the discovery of substantial copper deposits
within the tenement holding of > 800km2.
