Gold production for the quarter was marginally higher than budget at 25,233 ounces, at an average recovered grade of 11.05 g/t gold and cash costs of US$194 per ounce, inclusive of royalties and local business taxes. The increasing amount of development ore treated has contributed to the slightly lower head grade during the quarter.

 

Medusa, an un-hedged gold producer, sold 21,423 ounces of gold at an average price of US$1,518 per ounce during the quarter.

 

A graphic of actual production ounces and cost per ounce by quarters for the last four quarters is highlighted in Graph 1.

Preliminary Development Timetable

 

Graph 2 (please see link at the end of this announcement) has been extracted from the May 2011 Investor Presentation and shows the Preliminary Development Timetable for the new Co-O Mill followed by the Bananghilig Project.

 

New Co-O Plant

 

In November 2010, the Board approved the construction of a new plant with capacity to produce 200,000 ounces of gold per year based on processing up to 750,000 tonnes per year at the current reserve grade of the Co-O Mine.

 

On 22 June 2011, the Company announced that it has evaluated three sites, being two adjacent to the mine (11 kilometres from the current mill) and the third being the complete remodelling of the current mill site. The initial Capex was estimated at US$80 million inclusive of mine development and Saga Shaft.

 

The recommendation from the Company's consulting engineers after taking into consideration our current operating environment and community relationships, and the availability of multiple sites for additional tailings dams at the current mill site, was to extensively remodel the current mill site which would maximise the use of the existing facilities. At this point, this will result in cost savings of around US$10 million thus reducing the estimated Capex to US$70 million inclusive of mine development and the Saga Shaft.

 

The application to upgrade the Environmental Clearance Certificate for the current Co-O Mill has been submitted to the Department of Environment and Natural Resources and is currently undergoing assessment.

 

Preliminary works commenced in July 2011 for the replacement and transferral of buildings and facilities around the current mill to make room for the expansion.

 

Quotations have been received for the main long lead time items for the new mill. The order for the SAG mill is currently being placed.

 

Operations

 

Mine Development

 

During the quarter some sinking delays were experienced due to sourcing sufficient and on-going quantities of the correct grade of steel for the steel sets for the Saga Shaft. This has been rectified and sets are now being manufactured on site and installed as required. Following installation of the upper sets, the sinking has reached 63 metres and the shaft plan has been finalised to provide ore haulage from Levels 6 (250 metres below surface) and 8 (350 metres below surface). Completion is estimated to Level 6 late in the December quarter and ore haulage from Level 6 anticipated to commence late in the first quarter of CY 2012. A new winder for the Saga Shaft has been ordered.

 

Acceleration of the lateral development is on-going to ensure the underground infrastructure and on-vein development will be in place as the Saga Shaft reaches Level 6, then Levels 7 and 8. This accelerated development, from approximately 500 metres per month to approximately 800 metres per month, is programmed to continue for approximately the next 18 months and is increasing the proportion of development ore supplied to the mill.

 

Development on Level 6 is continuing mainly to the east from the Sabor Shaft.

 

The new Level 1 adit (Fig. 3) has advanced 235 metres.

 

Mine Production

 

Production has continued uninterrupted at the mine. All surface stockpiles have been depleted and underground broken ore is approximately 54,000 tonnes.

 

Mill Expansion

 

Installation of the two new leach tanks and the expansion and upgrading of the gold room have been completed.

Resource Estimate

 

A new resource estimate was undertaken by Cube Consulting Pty Ltd as contained in the announcement on 27 July 2011 which contains the plan view of the veins at Level 6 and the 3D resource model and additional details. The resources are estimated as follows:

Mine Resource Drilling

 

Detailed information is contained in the announcement dated 9 July 2011 which lists intersections down to 0.2 metres wide downhole.

 

The surface drilling was changed to focus to the east of the Oriental Fault in the vicinity of the Saga Shaft to facilitate mine planning close to this major new shaft. A number of new veins have been discovered in this area, and except for the Royal Veins which come almost to surface, the tops of the East Agsao set of veins where the economic grades generally start is between Level 4 and 5. Above these levels the veins are represented by argillised faults containing poorly formed vein material, breccias and silicification with grades generally

 

Some drilling also focussed on drilling at depth on the southern side of the mine to extend the Roysan Vein and associated veins to depth to around Levels 6 to 8 and to the east. At present, below Level 6, this drilling in combination with previous drilling has outlined 14 veins to the south of the Saga Shaft with indications of an additional three veins further to the south. The eastern-most hole EXP083 intersected five potentially mineralised structures (assays awaited) between 660 and 800 metres down hole.

 

Figure 3 (please see link at the end of this announcement) shows the Co-O Mine MD series of diamond drill holes from MD306 to MD308 totalling 1,928 metres completed in three holes, the EXP066 to EXP086 drill hole locations comprising 22 holes for a total of 13,302 metres up to completion of EXP086. Thirteen of the completed holes were over 800 metres deep with the deepest hole, EXP073 at 905 metres which recorded three high grade intersections between 800 and 900 metres down hole.

 

Table III lists the surface diamond drilling results greater than 3 g/t gold over ≥0.5 metres from the Co-O Mine for new drill holes MD306 to MD308 as well as results not previously reported for MD302, MD304 and MD305.

 

Figure 4 (please see link at the end of this announcement) shows the recently completed underground drilling totalling 7,102 metres in 31 holes. Table IV lists underground drill hole results since 25 March 2011. Assays are awaited for holes L4-017, L4-021, L5-051 to L5-052, L5-054 to L5-056, as well as L6-001 and L6-002. Additional assays are reported for holes L3-018, L4-010 to L4-011 and L5-026 to L5-047.

 

Table V shows the results >3 g/t gold over ≥0.5 metres for holes EXP065 to EXP086. Additional assays are awaited for EXP075 and EXP079 and all the assays are awaited for EXP076, EXP078 and EXP080 to EXP086. Additional assays are reported for holes EXP053, EXP063 and EXP064.

Co-O Drill Hole Sampling and Assaying Procedures

 

Samples are taken from mainly HQ sized (hole outside diameter 96 mm, hole inside diameter 63.5mm) and some NQ sized (hole outside diameter 75.8 mm, hole inside diameter 47.6 mm) drill core. The selected sample intervals are halved by diamond saw and half the core was bagged, numbered and sent to the Company laboratory. In a small number of cases to confirm the geological logging, the selected interval was re-split and ¼ core re-submitted for assay.

 

Initial sample preparation and assaying is undertaken at the Company's on-site laboratory. Samples are dried at 105ºC for 6 to 8 hours, crushed to less than 1.25 cm by jaw crusher, re-crushed to less than 3 mm using a secondary crusher followed by ring grinding of 700 to 800 grams of sample to nominal particle size of less than 200 mesh. Barren rock wash is used between samples in the preparation equipment. The samples are assayed by fire assay with Atomic Absorption Spectrometer (AAS) finish on a 30 gram sample. All assays over 5 g/t gold are re-assayed using gravimetric fire assay techniques on a 30 gram sample.

 

Check assaying of approximately 50% of samples used in the yearly resource estimates is undertaken by McPhar Geoservices Phils Inc ("McPhar"), a NATA and ISO 9001/2000 accredited laboratory in Manila. The pulps are airfreighted to McPhar who fire assay 30 grams of samples using AAS finish and a selected number of samples are checked using gravimetric fire assay techniques. Duplicate samples and standards are included in each batch of check samples. When reporting results, where available, the assays of McPhar as an independent laboratory have been given priority over the Company laboratory's results.

TENEMENTS

 

Subsequent to the March 2011 quarterly report, the Company has been advised of a clerical error regarding the newly granted Exploration Permits ('EPs") as previously reported. The corrected numbers for these tenements are EPs 031-XIII and 032-XIII (previously reported as EPs 030-XIII and 031-XIII respectively).

 

TAMBIS REGION

 

The Tambis project, currently comprising the Bananghilig Gold Deposit and the Kamarangan copper-molybdenum porphyry prospect (Fig. 5), is operated under a Mining Agreement with Philex Gold Philippines Inc. over Mineral Production Sharing Agreement ("MPSA") 344-2010-XIII which covers 6,262 hectares.

 

BANANGHILIG GOLD DEPOSIT

 

Validation drilling of the resource and extensional and scout drilling is continuing with six rigs. It is planned to commence drilling at the Canugas gold target (Figs 5 and 6) during July with a seventh rig.

 

An extensive Induced Polarisation ("IP") and ground magnetics programme is underway.

 

A comprehensive update on the Bananghilig drilling is planned for late in the September 2011 quarter.

 

TAMBIS REGIONAL GEOLOGICAL SETTING

 

A comprehensive regional mapping and sampling programme commenced in late CY 2010. The following sections are extracted from the announcement dated 10 May 2011 which contains additional detailed information.

 

The Tambis regional geology 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.

 

LOCAL GEOLOGICAL SETTING

 

Figure 5 (please see link at the end of this announcement) shows the geological setting which is characterised by a shallowly eroded extensive volcanic and sub-volcanic intrusive, multi-phase diatreme complex which is similar to the well known Philippine gold districts of Surigao in northern Mindanao, and Baguio and Mankayan in northern Luzon. The Baguio District is recorded as producing 28 million ounces of gold and is far from mined out.

 

The intrusive complex comprises predominantly andesite porphyry, feldspar porphyry, porphyritic andesite with smaller stock-like bodies of dioritic and dacitic composition. Figure 5 (please see link at the end of this announcement) also radiometric anomalies and aeromagnetic features, the copper prospects and generalised gold prospects and vein systems.

 

Figure 6 (please see link at the end of this announcement) shows the zones and names of the main mineralised quartz veins and stockwork areas which appear to be controlled by structural corridors which are orthogonal to the northwest-trending Barobo and Lianga Faults which in turn are sub-parallel to the Philippine Rift Fault direction. The main designated mineralised areas within the northeast corridor are Supon - Bananghilig, Malinao, Tagabaca, Canugas and Lansang which are discussed below except Malinao which will be discussed in the update on drilling in the September quarter.

 

PROSPECTS 

 

Copper Prospects

 

Lower Bananghilig River copper prospect

 

Outcropping copper-rich quartz stockwork veining in propylitically altered volcanics have been located over an area of approximately 50 metres by 30 metres. Chip samples have returned up to 0.16% copper and 0.35 g/t gold. Work is continuing to locate any additional stockworks which may be indicative of nearby or underlying porphyry style mineralisation.

 

Sawahon copper prospect

 

Outcrops of strong magnetite-clay-pyrite altered microdiorite with chalcopyrite-bearing sheeted veinlets with chip assays up to 0.27% copper and 0.16 g/t gold were located in Sawahon Creek. Reconnaissance samples of altered diorite along creeks returned up to 0.44% copper plus 0.10 g/t gold. This zone is located near the intersection of the Auron and Melendres Veins with the northnorthwest-trending Canugas Landsat Lineament and the copper-bearing veinlets are oriented parallel to the Canugas Landsat Lineament. The extent of the outcropping mineralisation is still being delineated.

 

Copper-rich quartz vein stockworks in variably silicified and argillically altered volcanics adjacent to the western side of the Sawahaon diorite have also been recently located and sampled.

 

A programme of ridge and spur sampling is planned for the Sawahon and nearby mineralised Canugas milled breccia pipe (described below).

 

Supon prospect

 

The Supon prospect area consists of the fertile Supon Diorite which contains disseminated chalcopyrite, an argillised quartz dacite porphyry, and some adjacent outcrops of oxidised copper-bearing silicate-sulphide skarns.

 

Gold Veins and Stockworks

 

Figure 6 (please see link at the end of this announcement) shows the four main areas of quartz veins and stockworks described below which comprise a regional scale northeast-trending structural corridor of anastomosing vein systems and pervasive argillic alteration.

 

 

Gold mineralisation is present in all areas as quartz veins, vein breccias, stockworks and silicified structures. These styles are typical for an intermediate sulphidation, epithermal gold breccia-type system.

 

Tagabaca area

 

There are currently two zones with potential quartz stockwork bulk mineable mineralisation. Both are open to the northeast towards Canugas.

 

Zone 1: This zone occupies an intensely altered area of approximately 500 metres by 350 metres with three identified sub-parallel vein zones (Polonio 2, Auron, and Melendres). Strongly developed quartz-sulphide stockworks over a width of 35 metres were recently mapped near the Melendres Vein. Peak gold assays from reconnaissance sampling include 69.61, 6.90, 4.67 and 4.35 g/t gold.

 

Zone 2: This zone sits along the northeast trending Polonio 1 Vein and the Canugas interpreted aeromagnetic feature. Assays from reconnaissance sampling, include 85.79, 6.49, 5.60 and 4.39 g/t gold.

 

Canugas area

 

The Canugas area abuts the Tagabaca prospect areas where the four Tagabaca veins, Polonio 1, Polonio 2, Auron and Melendres Veins, continue through the Canugas area. Two zones have been identified so far

 

Zone 3: This zone comprises two areas:

 

i. The intersection of the Polonio 2 and Vargas Veins with the interpreted northeast-trending Canugas aeromagnetic structure and the north-northwest trending Canugas Landsat Lineament where quartz stockworks have been located along road cuttings but have not yet been sampled. Previous reconnaissance assays returned up to 3.23 g/t gold.

 

ii. The Canugas milled breccia trends north-northwest and is located approximately 300 metres north of the known Sawahon porphyry copper outcrops. It was explored and partially mined for high grade (up to 1,000 g/t gold) mineralisation by underground development pre-WWII and again in the 1950s through tunnelling and drilling. The area exhibits widespread strong argillic and chloritic alteration. The Canugas breccia pipe is at least 80 metres long by up to 17 metres wide and is composed of fragments of sub-rounded to rounded hornblende andesite and some diorite fragments which are all strongly silicified and with pervasive disseminated pyrite. Some fragments also contain minor disseminated sphalerite and galena. Other adjacent smaller pipes have also been located as well as numerous narrow pebble dykes cross-cutting the volcanic rocks. Rock chip assays are still pending.

 

Zone 4: Sawahon Copper Area. This zone is located near the intersection of the Auron and Melendres Veins with the north-northwest-trending Canugas Landsat Lineament and is described in more detail in the Copper Prospect section above.

 

Lansang area

 

The Lansang area currently consists of two zones and is located adjacent to and along strike from the Canugas prospect.

 

Zone 5: This is the main Lansang Vein zone which was the site of extensive local mining in the 1990s. The main area of workings is centred on north trending Lansang 1 and Lansang 2 Vein zones which measure approximately 900 metres along strike and 150 metres wide. The quartz-sulphide veins are narrow at 0.10 to 0.50 metres wide (up to 23.49 g/t gold) but have extensive wide stockwork zones in both walls.

 

Zone 6: This comprises the north-northeast-trending Emben Vein zone. Preliminary examination of this zone shows it contains extensive fault gouge with chalcopyrite and minor sphalerite and galena, and patchy silicification and brecciation. Reconnaissance samples returned assays of 9.02, 8.0, 7.93 and 5.30 g/t gold. Further work is required.

 

Supon-Bananghilig area

 

Numerous veins and vein zones have been located within the Bananghilig area as depicted on Figure 6 (please see link at the end of this announcement). As a generalisation, work to date has shown that veins and/or structures that truncate the more ductile and permeable diatreme breccias zones tend to lose their vein style and form corridors of more disseminated styles of mineralisation associated with hydrothermal breccias and varying degrees of silicification.

 

The Supon prospect area contains the Jimmy Vein (and other un-named veins) which comprises epithermal vein and hydrothermal breccias across a total width of approximately 20 metres of variably silicified and argillised intrusives with pyrite and minor chalcopyrite indicating the structural zones seen at Bananghilig continue further to the southwest, a total distance from the eastern end of the Bananghilig Deposit to Jimmy Vein of approximately 1,000 metres. Other recently discovered old workings to the southwest of Bananghilig also indicate possible extensions to the southwest of the Ludetta Vein, and the Jacinto and Tinago Veins and their splits which extend southwest under younger limestone cover. New veins have also been recently uncovered during construction of drill roads.

USA PORPHYRY COPPER-GOLD PROSPECT

 

The Usa prospect is located within MPSA application XIII-00077 and the Company has a Memorandum of Agreement with Corplex Resources Inc.

 

An IP and ground magnetic programme is planned.

 

(Please see link at the end of this announcement for Figure 6) 

 

LINGIG

 

The Lingig prospect is located in Mineral Production Sharing Agreement 343-2010-XIII with an area of 3,824 hectares over which the Company has an operating agreement.

 

An IP and ground magnetics programme is planned for later in the year.

 

ANOLING

 

The Mines Operating Agreement with Alcorn Gold Resources Inc. covers MPSA application 039-XIII situated approximately 8 kilometres north from the millsite as shown on Figure 2 (please see link at the end of this announcement).

 

Processing of the MPSA is awaited.

 

Mapping and sampling is continuing. It is anticipated that drilling may re-commence during the next quarter.

 

SAUGON PROJECT

 

First Hit Vein

 

Background

 

Figure 2 (please see link at the end of this announcement) shows the Saugon Project located approximately 28 kilometres by road from the Co-O Mill. Work in 2004 involved drilling at the First Hit Vein (holes SDDH1 to SDDH35) in conjunction with underground development via a 30 metre deep inclined winze down the vein-breccia to assist in understanding the mineralisation.

 

Further details are contained in the announcements dated 20 April 2010 and 1 December 2010.

 

Drilling

 

Drilling has continued with three drill rigs however these rigs will be re-allocated to other projects. Regional mapping and prospect trenching are also in progress and IP programme is being planned to cover the main de-magnetised zone.

Mr Ciceron Angeles was appointed Non-executive Director of the Company on 28 June 2011.

 

TSX de-listing

 

The Company was officially delisted from the TSX on 17 June 2011.

 

Managing Director, Peter Hepburn-Brown commented:

 

"I am pleased to report that the Company's annual production of 101,474 ounces for this financial year is a new record. The forecast production of 100,000 to 110,000 ounces for the forthcoming financial year will allow the Company to balance production with increasing development rates. During July 2011 we commenced changes to the majority of our existing haulage shafts to facilitate the increasing rate of development and set the mine up for longer term benefits.

It is also pleasing to report an estimated US$10 million reduction in Capex for our proposed new Co-O Mill. We are in the final stages of preparing for the extensive remodelling and expansion of our current millsite and expect to commence re-location and construction of facilities during the September quarter".
