MML are an existing gold producer on the island of Mindanao, and are looking to expand production towards 100,000 ozs Pa during 2007.

Mining costs are low, around $250 per oz, and with gold around the $650 level, there is a healthy margin.

MML have returned good grades in recent exploration, and have an exploratory copper project within their licence area.

Co-O MINE CONCEPTUAL EXPLORATION TARGET ENHANCED BY DRILLING

24 August 2011

Medusa Mining Limited ("Medusa" or the "Company"), through its Philippines operating company, Philsaga Mining Corporation, advises that the release of the new resource model for the Co-O Mine and on-going exploration drilling results have significantly increased the support for the Conceptual Exploration Target ** for the Co-O Mine of:

3,000,000 ounces in 9,800,000 tonnes to 7,000,000 ounces in 23,500,000 tonnes using a grade range of 9 to 11 g/t gold with a preferred average grade of 10 g/t gold.

The combination of past production of approximately 450,000 ounces and the current global resource of 1,960,000 ounces indicates the deposit size is approaching the lower end of the Conceptual Exploration Target size range.

Detailed mapping and data compilation of the Co-O Mine vein system has been completed. It is a well preserved, intermediate sulphidation epithermal vein system with a large near surface, mushroom-shaped argillic alteration zone measuring over 1,500 by 1,500 metres in area and which grades into propylitic alteration to the east and at depth. The alteration and mineralisation trends indicate that the source of mineralising fluids is likely to be from beyond the current eastern end of the vein system.

Geoff Davis, Chairman of Medusa, commented:

"The Co-O Mine continues to expand, the more we drill the more we find, and we still cannot see an end to this extensive epithermal vein system. It is currently approximately 1.6 kilometres long and open to the east, and around 750 metres wide across the strike of the veins and still open both north and south, and as shown by drilling, it is also open at depth.

The size of the alteration envelope suggests there is the possibility of more vein systems contributing to this very large argillic alteration zone.

Drilling will continue with the six surface rigs and five underground rigs for the foreseeable future."

** The potential target size and grade is conceptual in nature, and there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being defined as a mineral resource.

CONCEPTUAL EXPLORATION TARGET SIZE

Discussion

Drilling since the previous estimate of the Conceptual Exploration Target announced on 18 January 2010 has continued to expand the vein system, as supported not only by the new global resource estimate of 1,960,000 ounces, but also by drill hole intersections in a significant number of veins to the north and east of the of the previous resource model.

The range for the Conceptual Exploration Target remains well supported at 3,000,000 ounces in 9,800,000 tonnes to 7,000,000 ounces in 23,500,000 tonnes using a grade range of 9 to 11 g/t gold with a preferred average grade of 10 g/t gold:

The additional support for this target is listed below:

- The total ounces already accounted by the current global resource and past production is approximately 2,310,000 ounces.

- An increase of 100 metres of strike length from 1,500 metres to 1,600 metres as supported by drilling as described in the announcement dated 6 July 2011.

- A change in the Specific Gravity ("SG") to the SG currently used of 2.62 for the resource estimates (previously 2.45 previously) resulting in a 7% increase in tonnes as reported in the announcement dated 22 July 2010.

- As shown on the composite longitudinal projection in Figure 2 (please see link below for Figure 2), all new drill holes since 30 June 2011 in the deposit with assays of >= 0.2 metres at >= 3 g/t gold up to 30 June 2011 are incorporated and support the mineralisation continuing to depth. The assays support levels between 500 metres and 750 metres below surface is a function of the amount of drilling completed to date.

Figure 1 (please see link below for Figure 1) shows the veins at Level 6 used in the new resource estimate published on 27 July 2011.

Figure 2 (please see link below for Figure 2) shows the projection of all drill intersections below Level 6. The new drill results from 01 July 2010 to 30 June 2011 enhance the support for mineralisation to continue to depth and to the east.

Co-O MINE GEOLOGY AND ALTERATION

The Co-O epithermal vein system is hosted by Eocene to Oligocene (within the Tertiary era) gently north-dipping, basaltic andesitic lavas to andesitic lavas and volcaniclastics. The sequence is intruded by andesitic to dioritic dykes and stocks and cut by north-trending faults with the Oriental Fault identified as the most significant fault at this stage.

The quartz veins are dominantly westerly trending and sub-vertical, with lesser 30 to 50 dipping. Some of the vein characteristics are:

- the veins are polyphasal exhibiting massive, banded and vein breccia textures and comprise two gold bearing phases, the first being a quartz- chalcedony +/- calcite phase deposited at a temperature of approximately 180 C, and a second phase comprising blocky calcite-quartz +/- barite;

- the high gold grades are associated with crustiform-colloform banding; and

- the sulphides comprise mainly pyrite, <1 to 5%, and minor sphalerite, chalcopyrite, galena.

Early fluid inclusion studies in the upper levels of the mine concluded:

- the temperature of formation was 200 to 250oC and within approximately 500 metres of the surface;

- the salinities of 1 to 13 wt% NaCl equivalent; and

- that the above ranges fall well within the epithermal range of deposition.

Figures 3 and 5 show the surface geology and the geology in cross-section. (Please see link below for Figures 3 and 5)

Figures 4 and 6 show the surface alteration and the alteration in cross-section. (Please see link below for Figure 4 and 6)

Alteration types identified are:

- silicic (quartz +/- illite-calcite) - confined to vein zones and hydrothermal breccias;

- argillic (illite +/- quartz-calcite) - surrounds the veins - millimetres to 100s of metres;

- chloritic (chlorite+/-smectite-calcite) - increases and finally dominates at depth with; and

- propylitic (chlorite-epidote +/- smectite-calcite).

At surface the mapped alteration shows that the:

- veins are within a laterally extensive mushroom-shaped argillic envelope which is

- in excess of 1.5 km x 1.5 km in area, and

- associated with gold vein mineralization;

- outlying chloritic to propylitic zone is overprinted by argillic alteration; and

- propylitic zone is considered to be regional in extent, i.e. pre-mineral.

The alteration patterns at depth are:

- the argillic envelope abruptly tapers down along the veins until only a few metres to millimetres wide;

- the chloritic to propylitic alteration zone increases and finally dominates at depth; and

- there appears to be no identifiable pattern between the chloritic and propylitic zones.

Comments today from one of their brokers:

Medusa Mining (MML LN) 425p, mkt cap 850m Fatality at Co-O gold mine
BUY - target price 573p
Medusa Mining has announced a fatality at its Co-O gold mine
The accident was caused by bridging of ore within the mine stope.
The miner was standing on the ore pile above the cavity when the bridged ore collapsed above the ore chute.
This is an extremely rare type of accident and is difficult to protect against.
The stoping area involved is closed for the duration of the investigation and this will reduce gold production at the mine.
Other parts of the mine continue to work normally including stopes which are unaffected by the investigation.
The mine employees 2,700 workers with around 1,000 involved at the mine.
Management will move to limit the risk of this sort of incident happening again but the ongoing expansion of the underground operations and its workforce does raise the risk of injury and fatality within the mine and also within the surface mine area.
The training and education of new miners is critical for the mine and the development of an experienced workforce is important from a safety perspective.
Medusa is using a long standing and well proven mining method which should limit the number of lost time incidents within the mine.
Development of the mine and its shafts will improve access.
Medusa hit record production of 101,474oz in the year to end-June 2011 and should raise production levels next year to potentially exceed this annualised production rate.
We forecast Medusa should produce around 105,000oz for FY 2012 and expect gold production to ramp up in the second half to make up for lower production in FY H1.

AGM. Production revised slightly down this year but doubled next year.dividend increase definite in the future.Exploration and improvement from profits.Costs under 200 dollars per ounce. Positive.

Back over £4 after bad news and a bad run on the share price.

MML has taken a bit of a hammering of late,beginning to look like a real bargain? Keeping a close eye on this one,thats for sure.

From one of the most knowladgable pi's,regarding mining stick,from about 2 weeks ago.
-------------------------------------------------------------------


Surprising to see MML down near 300p when they have just announced Saga commissioning and the commencement of the ramp-up to 200koz pa. But as we have already discussed, the market pays a lot more attention to TA than it does to fundamentals, and there is a clear history of bouncing off support in this area.

So I will just practice what I am forever preaching and add more stock on this dip.

We all know the best time to buy a stock (which has good fundamentals) is when the SP is depressed and sentiment is at it's worst. Conversely, the best time to lighten-up is when everyone wants to buy-in on a wave of greedy euphoria.

">

Nearly time to buy. Quite a volatile stock. May take a sudden upturn,but might be waiting for positive news which WILL come but there is still possibility of delays and production not up to expectations. Rolls a bit with the gold price,but with production expected to increase dramaticaly over the next two years with the implication of mine modifications and guaranteed reserves this must very near the bottom line.

UT @280p as you say,nearly time to buy>

http://www.investegate.co.uk/medusa-mining-ltd/mml/coo-drilling-update/201302210700153687Y/?fe=1&utm_source=FE%20Investegate%20Alerts&utm_medium=Email&utm_content=Announcement%20Alert%20Mail&utm_campaign=Medusa%20Mining%20Ltd%20Alert

This becoming a real bargain imho,jist awaiting a little longer to see where it evens out.

In at 272p.

Sorely tempted,but i'll wait and see what the Aussie's make of the news,especially as ut's end of the week?

DRAT,missed it,too clever by half. UP almost 30p.

500p target by year end.

Congrats on your timing,still kicking muself. But it's still well undervalued at this SP.Can't believe i dithered at 272p,when i'd be watingfor a dip to around £3.

Managed to get in sub £3,looks like just in time?
