EXECUTIVE ORDER ON MINING IN THE PHILIPPINES

On 06 July 2012, Philippine President Benigno Aquino III signed Executive Order No. 79 entitled "Institutionalizing and Implementing Reforms in the Philippine Mining Sector Providing Policies and Guidelines to Ensure Environmental Protection and Responsible Mining in the Utilization of Mineral Resources" ("EO 79").

On 10 September 2012, the Department of Environment and Natural Resources ("DENR") issued Administrative Order No. 2012-07 ("Rules and Regulations to Implement EO-79" or "EO-79 IRR"), and on 08 October 2012, issued Administrative Order No. 2012-07-A2 ("EO-79 Amended IRR") to revise Sections 3, 7 and 9 of EO-79 IRR. EO-79 IRR and its amendments took effect on October 25, 2012.

The implications of the EO-79 with regards to the Company's projects are discussed in the June 2012 and September 2012 quarterly reports to the ASX. There has been no change in the Company's view since then.

The new legislation on mining taxes and royalties is yet to be finalised for submission to Congress.

On March 07, 2013, the Secretary of the Department of Environment and Natural Resources (DENR) approved the lifting of the moratorium on acceptance of applications for Exploration Permits and Financial and Technical Assistance Agreements.

MINERAL RESOURCES and ORE RESERVES

The Company's current resources (including the Saugon resource) and ore reserves are shown in Table I. No allowance has been made for mine depletion subsequent to the new resources and reserves for 2013/2014, which were announced on 08 August 2013.

Co-O MINE

Gold Production

Production statistics for the last four quarters are summarised in Table II below.

Table II. Gold production statistics

The Company produced 14,502 ounces of gold for the quarter, at an average head grade of 5.68 g/t and cash costs of US $ 338 per ounce, inclusive of royalties and local business taxes.

Gold production for the quarter was lower than forecast due to commissioning issues with the New Mill (announcement 4^th September). These Powercell issues have continued on into the December quarter (announcement 23^rd October).

Operations

Mine Development

The 8L Shaft has been operating and during October, new sheave wheels, ropes, skips and man cages were be fitted to the Shaft.

The ore pass system from the 6L to 8L loading pocket was completed and is operational.

Development continued on Levels 1 to 6, commenced development on the 7L and continued development on the 8L where during the quarter, the Catto, Jereme and Great Hamish Veins were intersected.

Development continued on the Don Pedro Vein which is a N-NW trending vein.

Co-O Mill

The New Mill commenced commissioning in August, but was halted when the Powercells which drive the Sag Mill motor failed and had to be returned to the Vendor's workshops in China for repairs. These repairs have taken longer than was first indicated by the Vendor, (announcements 4^th September and 23^rd October)

At the same time as returning the faulty Powercells to China, a set of new Powercells were ordered and will be available to send to site at the end of November 2013. These will be spare powercells for the operation.

The current mill continues to operate and produce gold. This mill will continue to operate during the commissioning of the New Mill and will continue until the New Mill reaches its capacity of 2,500 tonnes per day.

The Detox, Thickener, CIL tanks, Gold Room and associated equipment with "Wet" processing were all successfully commissioned and operated during the quarter.

Co-O Mine Drilling

Underground drilling was carried out during the quarter utilising 2 large and 2 smaller portable diamond rigs. At total of 21 holes were completed at Levels 2, 3 and 8 for an advance of 5,051.76 metres.

Co-O EXPLORATION

IP Survey

The ground Induced Polarisation ("IP") survey is ongoing within the Co-O tenements including the Co-O mine environs. Up to the end of the September quarter, approximately 60 line kilometres of IP survey were completed. It is anticipated that the remaining balance of the IP survey (171 line kilometres) will be completed during the March 2014 quarter, with interpretation being carried out during the March/June 2014 quarters.

Ground Magnetics Survey

A Ground Magnetics survey was commenced during September, using the same grid as the IP survey. A total of approximately 44 line kilometres was completed up to the end of the September quarter. The survey is expected to be completed at the same time as the IP survey, with interpretation being carried out concurrent with the IP interpretation.

Reconnaissance Programmes

Reconnaissance mapping and sampling programmes are ongoing.

TAMBIS REGION

The Tambis project comprising the Bananghilig Gold Deposit (Figure. 2) 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.

The Executive Order on Mining (EO-79) signed on 6 July 2012, by the President of the Philippines, will have no immediate impact on the Bananghilig Project as the Company can continue to explore, conduct feasibility studies and planning.

BANANGHILIG GOLD DEPOSIT

The announcement of 12 September 2011 summarises the Tambis regional geological setting, local geological setting, deposit description and mineralisation. Additional information is contained in the September 2011 quarterly report dated 24 October 2011, drilling updates on 17 January 2012, 8 August 2012, 21 November 2012 and 02 April 2013, operations update on 08 July 2013, and resource estimation updates on 29 January 2013 and 08 August 2013.

Indicated & Inferred Mineral Resource Estimation

On 08 August 2013, the Company announced the results of resource estimation undertaken by Cube Consulting Pty Ltd of Perth, Western Australia. The Indicated Mineral Resource estimate for the Bananghilig Deposit comprises 766,000 ounces of gold at 1.48 g/t gold in 16,060,000 tonnes and an Inferred Mineral Resource of 370,000 ounces of gold at 1.36 g/t gold in 8,460,000 tonnes using a cut-off grade of 0.8g/t gold. The 08 August 2013 announcement includes a summary of the parameters utilised in the resource estimation.

Bananghilig Scoping & Pre-Feasibility Study

On 09 April 2013, the Company published the results of a first pass Scoping Study¹ of the Bananghilig Gold Deposit. The Scoping Study was conducted to ± 25% accuracy and the results considered positive, warranting the commencement of a Feasibility Study to be undertaken by external consultants. The Scoping Study parameters and discussion on other parameters, including metallurgy, mining and operations is included in the 09 and 11 April announcements.

A Feasibility Study has been ongoing since the completion of the Scoping Study. Sterilisation and geotechnical drilling programmes were almost complete at the end of the September quarter with only a few geotechnical drillholes remaining to be drilled. A total of 42 holes were completed for a total advance of 3,650.95 metres.

A decision has been made to temporarily suspend the feasibility study given the mineralisation being encountered at the new B2 discovery area, as well as given consideration to the current gold price and commissioning of the new Co-O

B2 Discovery Area

During the March 2013 quarter, the Company announced the discovery of a new zone of gold mineralisation proximal to the current Bananghilig gold deposit (Figure 3). The results of subsequent drilling (refer table IV below, June 2013 quarterly report, and announcement on 08 July 2013) are believed by the Company to have implications to the development of the current Bananghilig resource.

During the September reporting period, two large capacity diamond drilling rigs completed 14 diamond drill holes (TDH313-314, TDH316-317, TDH319, TDH321-323, TDH325-328 & TDH330-331) for a total advance of 3,992 metres.

Figure 3 shows the Bananghilig area geology and the position of the new B2 mineralisation discovery, beneath the limestone cover, relative to the Bananghilig resource.

B2 Drilling Results

Drilling at B2 was carried out during the September reporting period with two diamond rigs drilling on a closed spaced (20-40 metres) pattern adjacent to hole TDH284, as well as on a 150 metre x 150 metre grid pattern. Results from subsequent drilling have since been received and significant intercepts for completed drillholes are included in Table IV below.

Geotechnical and Sterilisation Drilling Programmes

The Geotechnical drilling and test pitting programmes were completed in first week of October. Drilling was carried out to investigate sites suitable for infrastructure associated with the potential development of the Bananghilig resource, including plant site, waste, tailings and process water storage facilities. Sterilisation drilling programme was completed in the same areas. To date no significant assay results have been received for these areas.

Regional Exploration

Reconnaissance mapping and sampling is on-going within the Tambis Region.

BANANGHILIG 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, or HQ3 (hole diameter 96 mm, core diameter 61 mm). The holes are initially collared using PQ drillbits (hole diameter 122 mm) to recover PQ3 core (core diameter 83 mm) until the drillbit encounters competent ground, then the hole is cased, and the coring bit reduced to HQ3 for the remainder of the drill hole. If difficult conditions are encountered, then the drill bit is changed to NQ3 (hole diameter 75 mm, core diameter 45 mm) and the hole continued until the planned depth or bad ground conditions prevent further drilling, whichever occurs first.

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 results is on-going.

Analytical Procedure

Sample preparation is undertaken by Intertek at their Surigao City laboratory, where each sample is registered, dried at 105ºC 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 75μm (200 mesh).

Quality control procedures include a 1 in 15 resplit after crushing for partial preparation and after pulverising for total preparation. These resplits are also analysed and included in the analysis report. Four 250 gram splits are obtained, one for sample analyses and the remaining three for storage for future reference.

Pulverised samples are analysed by classical fire assay techniques on a 50 gram charge with Atomic Absorption Spectrometer ("AAS") finish.

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.

The Induced Polarisation, Resistivity and ground magnetics surveys have been completed. Data processing and interpretation have been completed by an independent geophysical consultant. A final report has just been received and is being reviewed prior to defining drill targets.

Detailed geological mapping and soil sampling programmes are in progress.
