ANNOUNCEMENT
21 November 2012
BANANGHILIG DEPOSIT - RESOURCE DRILLING UPDATE
(ASX & LSE: MML)
Medusa Mining Limited ("Medusa" or the "Company"), through its Philippine's operating company, Philsaga Mining Corporation, advises that infill drilling has recently been completed at the Bananghilig Gold Deposit. A significant number of infill drilling results were included in the previous announcement of 8 August 2012. Drilling since the 8 August 2012 announcement continues to confirm continuity of mineralisation as well as indicating extensions to the mineralisation.
Drilling highlights include:
Hole Number Width Grade (uncut) (metres) (g/t gold) ------------- ---------- -------------- TDH 249 3.00 47.95 ------------- ---------- -------------- TDH 252 14.00 1.37 ------------- ---------- -------------- TDH 260 10.35 1.34 ------------- ---------- -------------- TDH 261 6.20 2.70 ------------- ---------- -------------- TDH 262 6.00 1.99 ------------- ---------- -------------- TDH 267 5.60 2.23 ------------- ---------- -------------- TDH 273 15.50 1.60 ------------- ---------- --------------
Peter Hepburn-Brown, Managing Director of Medusa, commented:
"It is pleasing to see the infill drilling continue to confirm continuity of the mineralisation. The infill drilling has been topographically constrained in some areas in which case further infill drilling to upgrade these areas will be undertaken once permitting progresses and prior to commencement of mining. Based on the continuity demonstrated to date, we are confident that further infill drilling will also be positive."
BACKGROUND
The Tambis Project, which includes the Bananghilig Gold Deposit, is operated under a Mining Agreement with Philex Gold Philippines Inc. over Mineral Production Sharing Agreement ("MPSA") 344-2010-XIII, which covers an area totaling some 6,262 hectares.
For additional regional geological and mineralisation information, and drilling results, reference can be made to previous announcements released on 10 May 2011, 12 September 2011, 17 January 2012 and 08 August 2012.
REGIONAL GEOLOGICAL SETTING
The Tambis regional geology (Fig 1), termed the Tambis intrusive-breccia complex, typifies a structurally complex intermediate-sulphidation, epithermal gold, breccia-type system, including disseminated gold overprinting the host Tertiary-age igneous package which had been emplaced into an andesitic volcanic basement. The fertile igneous suite comprises a multi-phase calc-alkaline, high level, sub-volcanic intrusive package cut by extensive bodies of phreatomagmatic diatremes and hydrothermal breccias.
BANANGHILIG DEPOSIT
Geological summary
The Bananghilig Deposit currently consists of three zones, each approximately 1 kilometre long and open in all directions, locally termed the Sorex, Garden and Malinao zones. These zones are broadly defined on the basis of the projection in plan of >=0.5 g/t gold drill hole intersections.
The mineralisation is located partly within the Bananghilig diatreme breccia which measures at least 1,000 metres west to east and still open to the south beneath the younger sediments, and also around the diatreme margins and in the country rocks along structural corridors.
The diatreme breccias contain unsorted fragments of the andesitic basement as well as fragments of the later intrusive rocks predating the diatreme events in a matrix of comminuted rock flour and magmatic crystals. Fragment sizes range from granule-sized to building-sized mega-blocks which have been torn off the walls of the diatreme during the multi-episodal explosive activity. The explosive activity also fractured the mega-blocks and wall rocks, preparing them for subsequent mineralisation deposition.
Drill Results
During the period 1 August to 30 September 2012, 23 diamond drill holes (numbered TDH 248 to TDH 273) have been completed for a total advance of 4,351 metres. Holes TDH 250, TDH 258 and TDH 270 have been drilled outside of the Bananghilig deposit area.
Figure 1 shows the drill holes completed. Assays have now been received for all drill holes completed for this Phase 1 programme.
First pass assaying for gold has been undertaken on all samples submitted to the laboratory. Additional assaying is on-going from selected intervals for base metals, silver and other elements.
The results are summarised in Table 1 where significant intercepts are defined on the following basis:
(i) lower cut-off grade of 0.5 g/t gold, and (ii) >= 5 metres down hole intercept width at >= 0.5 g/t gold, or (iii) <= 5 metres down hole intercept width at >= 5 gram per metres, and (iv) maximum of 3 metres of down hole internal dilution at <=0.5 g/t gold

DRILL HOLE SAMPLING AND ASSAYING PROCEDURES
Drilling Procedures
Drilling, sampling and analytical methodologies are of internationally acceptable standards. Drilling and analyses are carried out by independent contractors, SBF Philippines Drilling Resources Corp. ("SBF") and Intertek McPhar Mineral Services Inc. ("Intertek") respectively.
Drilling is carried out by SBF using wireline diamond coring techniques, with the core being predominantly HQ triple-tube (HQ3) diameter (OD 61 mm). The holes are initially collared using PQ drillbits (OD 123 mm) to recover PQ3 core (OD 83 mm) until the drill bit encounters competent ground, then the coring bit is reduced to HQ3 for the remainder of the drill hole. If difficult conditions are encountered, then the drill bit is changed to NQ3 (core OD 45 mm) and the hole continued until the planned depth or bad ground conditions prevent further drilling, whichever occurs first. Core recovery is generally better than 95% and is considered to be good.
Drill Core Sampling
Drill core is recovered from the inner tube and handled carefully to preserve the integrity of the drill core. Structural measurements are taken including Rock Quality Determinations ("RQD") and Fracture Densities. The core is then placed in plastic core trays, aligned, photographed and marked up for sampling.
The drill core is then cut in half by diamond core saw and sampled at one metre intervals or at lithological boundaries. The samples are placed in individually labelled plastic sample bags, a sample number ticket included, and then sealed for despatch to Intertek's Sample Preparation laboratory in Surigao City. The integrity of the core samples is supervised at all times by the geologists until despatch to the laboratory where they are accompanied by company personnel until receipt by Intertek.
One Certified Reference Material ("CRM"), one Blank and if possible, one Duplicate is included within each successive group of twenty samples that are submitted to the laboratory. QA/QC monitoring of the drilling program and the laboratory's results is conducted as an ongoing process.
Analytical Procedure
Sample preparation is undertaken by Intertek at their Surigao City laboratory, where each sample is registered, dried at 105degC for 6 to 8 hours and crushed to 95% passing 2 mm by jaw crusher, before a 1kg split is taken for fine pulverising, using a riffle splitter or rotary sample divider. Pulverised sample is nominally pulverised to 95% passing 75<MU>m (200 mesh).
Quality control procedures include a 1 in 15 re-split after crushing for partial preparation and after pulverising for total preparation. These re-splits are also analysed and included in the analysis report. Sizing tests are carried out on 1 in 20 assay pulps at 75<MU>m (200 mesh) to monitor the pulverising stage. Four 250 gram splits are obtained, one for sample analyses and the remaining three for storage for future reference.
Standard laboratory procedure is to clean the crusher and pulveriser after every fifth and each sample treatment respectively with barren material and/or bowl wash, to minimise carry-over contamination.
Pulverised samples are analysed by classical fire assay technique on a 50 gram charge with Atomic Absorption Spectrometer ("AAS") finish by Intertek at their Manila Laboratory. All assays over 5 g/t gold and other selected samples are re-assayed using the same technique.
