    SAG Mill Refurbishment
    ----------------------
    The refurbishment of the semi autogenous ("SAG") mill has been completed
at Weir Minerals (Australia) Ltd's workshop in Edmonton, Canada. The mill
components were transported to Seattle, USA and then onto a cargo vessel for
shipment to the Philippines where they are expected for arrival towards the
end of July 2008.
    The mill motors refurbishment is also complete and the motors and gear
boxes are scheduled to leave the USA in early August.

    SAG mill refurbishment did not identify any major structural issues and
the mill will arrive onsite in early August in as new condition. SAG mill
installation is scheduled to begin on site early August. Mill installation is
within the Leighton EPC scope.

    Ball Mill Refurbishment
    -----------------------
    The refurbishment of the two ball mills is 90% complete with the two mill
shells to be shipped from Cebu to the Masbate project site during the week
starting 14 July. The remaining componentry is being fabricated/repaired at
Tiger Engineering Works in Manila and is planned to be dispatched to site
during July. The installation of the mills on site will begin during August
and is within the Leighton EPC scope. The required additional two mill motors
have been ordered with the scheduled date of delivery not expected to affect
the project completion timeline.

    Tailings Storage Facility ("TSF")
    ---------------------------------
    The TSF construction preliminary work was commenced as a variation to the
Mining Alliance Contract (Leighton/Filminera Resources Corporation ("FRC")).
The sequence of construction has been altered from the original GHD
Engineering Pty Ltd plan to better meet the on site conditions.
    As at the end June the completed work represented 27% of the designed
main embankment Stage 1 construction. Negotiations for the additional works,
to be completed prior to project commissioning in February, are ongoing.

    Power Station
    -------------
    The Company with the assistance of Poyry Energy Inc. (electrical
engineers) and Leighton identified a number of power generation units which
were suitable for power supply at Masbate. Final negotiations with owners of
the power supply units in Taiwan and China were completed and initial (10%)
payments to secure the selected units have been made. The final installation
of a purpose built power station building at Masbate will comprise three (3)
6.3 mega watt (mw) and two (2) 5.5 mw generators. The units are powered by
slow speed heavy fuel oil. Negotiations are underway for the dismantling,
shipping and construction of the on site power station.
    FRC will invite the three main fuel supply companies in the Philippines
to tender for the supply of bunker fuel for the power station along with
diesel fuel oil for the mining equipment and suitable lubricants for both
functions.

    Permanent 300 Man Camp
    ----------------------
    Construction of the camp was completed so as to enable Leighton to
install the majority of their skilled construction workers in this facility.
Final commissioning and hand over of the facility will be carried out at the
completion of the EPC activities.

    Main Office
    -----------
    The building originally used as a hospital/clinic during operations in
the 1980's is being rehabilitated and fitted out to a standard suitable to
serve the purpose as a general office to accommodate the administration,
mining and geology departments.

    Guest House
    -----------
    The guest house accommodation and kitchen has been refurbished so as to
be suitable for visitors to the project site.

    Assay Laboratory
    ----------------
    Negotiations have commenced with the two (2) suitable contractors for the
fit out and operation of an accredited on site laboratory. FRC is in the
process of designing a suitable building for the laboratory.

    Clinic
    ------
    The existing construction clinic will be expanded/relocated to a standard
suitable for a mining operation. As the project is positioned close to the
permanent medical facility at Aroroy town, a complete hospital is not
required. An FRC ambulance is available to transport patients requiring
medical attention/hospitalisation to Aroroy.

    Security / Comrel Office
    ------------------------
    The existing project general office is being transformed to accommodate
the security and community relations function.

    Mining and Geology
    ------------------
    During the quarter the Company announced an updated resources estimate
completed by Mining Associates Pty Ltd which reported a 62% increase in
resources. The new resource based on a US$750 / oz gold prices and a 0.36 g/t
cut-off is:

    
    Indicated Resources - 153.41 Mt @ 0.92 g/t containing 4.55 M ounces
                          of gold

    Inferred Resources - 127.15 Mt @ 0.8 g/t containing 3.22 M ounces of
                         gold
    

    As the Company is planning to adopt a bulk mining approach to the
exploitation of these resources, following an initial period of high grading,
a revised geotechnical algorithm was used as compared to the 2006 estimate.
The result is therefore considered conservative in grade and it is expected
that the grade will be elevated when the mineral reserve estimate is
completed.
    Lower Quartile Solutions Pty Ltd ("LQS") has been commissioned to
optimise the resource estimate by the application of updated economic
parameters and to produce a revised mineable reserves statement including a
final mine plan. The mine production schedule will be further optimised to
mine only those resources that report grades above 0.7 g/t. Initial
indications (prior to final starter pit design) show that the average run of
mine grade for the first two years will exceed 2.0 g/t with a strip ratio of
less than 1 to 2 (ore t: waste t).
    The mobile equipment fleet has been ordered and will be delivered in
November so as to conform to the three (3) month pre production mining
schedule.

    Exploration
    -----------
    During the quarter the Company continued with its exploration program in
areas of known mineralisation refer Figure 1 which is outside the recently
compiled resources area (Panique). The more significant results included those
in Table 1 below.

    Safety
    ------
    The Masbate Gold Project has now operated a total of 281 days from
commencement of construction on September 24, 2007. As of June 30, the project
has accumulated site wide, a total of 2,491,744 man hours worked. Safety
statistics are compiled and benchmarked from September 24, 2007 which was the
date of actual work commencing. As of June 30, the project has operated 37
days since the previous lost time incident. The previous best record was 244
days worked with no lost time incident. FRC continues to build the capability
of its safety department and improve coordination with that of Leighton and
other contractors operating on the site. FRC remained in compliance with all
regulatory authorities.
    During the quarter, several safety training exercises were conducted in
compliance with the safety training program of the Company.

    Environment
    -----------
    The Masbate Gold Project remains in compliance with all environmental
laws and regulations.
    During the quarter water, air and sound have all been monitored such to
ensure these elements are within the allowable regulated limits.
    It has been identified that silt fences and settling ponds should be
installed to further improve the quality of the water entering the Panique
Creek. This is planned to be implemented early in July.
    The Company has adopted a Mining Forest, Green Philippines and Tree for
Life Programs as prescribed by the Government.

    Security
    --------
    The project continues to operate within a secure environment with no
major security breaches to report. During the quarter the staffing resources
of the security department have been increased in concert with the increased
activity related to the development of the Panique Tailings Storage Facility.
    The focus during the quarter has been on the prioritization, development
and implementation of required policies and procedures. Further development of
the emergency response team through training has been planned for the coming
months.

    Community Relations
    -------------------
    Ongoing efforts by way of community projects, employment, training and
information dissemination is further enhancing the community relationships.
During the quarter FRC continued its thrust to provide more labor
opportunities for the locals of Masbate in line with its efforts to bring the
Masbate Gold Project closer to the community.  The target of 70/30 (number of
locals from Masbate to others) hiring ratio of people hired by FRC, Leighton,
the Mining Department and Security is being exceeded.

                     Off Loading Barge at Masbate Jetty
    

    Expenditure
    -----------
    As of 30 June 2008, the group has spent US$68.7M on the development of
the Masbate Gold Project with total cash reserves at the same date of
US 45.34M (including the cash reserves of Filminera Resources Corporation).

    Project Finance Facility
    ------------------------
    During the quarter, full facility documentation for the US$80.3m facility
was signed and syndication completed by BNP Paribas, the bank arranging the
debt financing for the project. The banking syndicate will comprise 4 banks,
namely BNP Paribas, Standard Chartered, West LB and DZ Bank. The conditions
precedent to first drawdown are nearing completion, and are principally
procedural in nature now, with first drawdown currently expected at the end of
July 2008. As part of the initial drawdown process, the independent engineers
have undertaken a review of cost to complete and have allowed for an
additional contingency amount of US$5m (or 3% of the total budget of US$154M
which includes the additional power station costs of US$29m).

    Mkushi Project Update
    ---------------------
    The feasibility study ("FS"), being prepared in accordance with the
definition of such as stipulated in the NI 43-101, is progressing in line with
the schedule and remains on track for completion during the last quarter of
2008.
    Snowden Mining Industry Consultants Pty Ltd ("Snowdens") has completed
preparation of a resource estimate for the project and is preparing an NI
43- 101 compliant technical report. The global mineral resource has been
assigned an indicated classification according to the 2004 edition of the JORC
Code and NI 43-101.
    The resource estimate includes all drill results and data available up to
29 March 2008, but since March additional significant assay results have been
received and these will be included in any resource update.
    Exploration work being carried out by our partner African Eagle Resources
plc ("AFE") has continuing during the quarter.  At the Munda prospect, AFE
completed ten RC drill holes and six diamond drill holes for a total of 2223m.
 Visible sulphides were intersected in all the diamond holes, showing that
mineralisation extends over a strike length of 2km, but the assay results have
not yet been received.
    Multi-element assay results were received for the regional soil
geochemical survey, a 400m grid over an area of 400km(2) for a total of 2500
samples.  The results revealed low contrast copper anomalies at several
locations and showed an apparent concentric zoning around the main mineralized
area, indicative of an alteration system associated with the Munda Granite.
With the regional exploration programme now almost complete, AFE commissioned
a unified interpretation of the geochemical, geophysical and remotely sensed
data.
    AFE has also commissioned a helicopter electromagnetic ("VTEM") survey to
search for additional blind mineralisation at depth. The QA/QC is being
conducted in accordance with standard exploration practices.

    Feasibility Study - Summary
    ---------------------------
    Metplant Engineering Services/Bateman Engineering Pty Ltd ("Metplant"),
the principal consulting group carrying out the FS for the process plant area,
have made substantial progress, having signed off on the project
specification, the design criteria and the mass balance, and are now drafting
layouts. The mechanical equipment lists have been prepared and requests for
quotations on the major items have been issued to suppliers. The crushing
plant, which will be of a modular layout, is being designed by FL Schmidt
Minerals Pty Ltd in conjunction with Metplant.
    The application for a full mining licence was submitted after the Zambian
government lifted its recent moratorium on applications. We received a
"Notification of successful validation" of the application and now await
setting of the conditions and fees during the next phase of the approval
process.
    Snowdens has completed the resource evaluation, assigning a JORC and NI
43-101 compliant indicated classification to the mineral resource, with
results set out below.
    Discussions are advanced with the two main power suppliers in Zambia to
provide a secure supply of power to the operation. A review of diesel
generation will be undertaken for completeness.
    Neil Seldon & Associates Ltd has been engaged to provide copper price
forecasts, and smelter terms and to assist in negotiating preliminary
concentrate off-take arrangements in Zambia.
    The FS is on track for completion in the last quarter of 2008.

    Resource Drilling & Estimation
    ------------------------------
    Snowdens, an independent resource consultant based in Perth, has
completed their resource estimate for the Mkushi Copper Project to both JORC
and 43-101 guidelines.
    After reviewing the drilling and sampling data underlying the resource
estimate, Snowdens were of the opinion that the resource could be assigned an
indicated classification in accordance with the 2004 edition of the JORC Code
and NI 43-101. Snowdens visited the site on the 15 to 20 of April 2008 to
review the mineralization and data collection procedures.
    The deposit forms a sequence of en-echelon pods of chalcopyrite
mineralisation hosted by granitic schist over a strike length of approximately
1.9 km and with a width of about 230 m. Mineralisation occurs from near
surface, a few metres, down to approximately 250 m with each pod being several
metres to tens of metres thick. The chalcopyrite mineralisation has been
defined by three-dimensional geological interpretation at a nominal grade
cut- off of 0.1% copper. As a result the mineral envelope contains significant
internal dilution.
    The Mineral Resource estimate was undertaken using Datamine Studio
version 3 software and based on data and mineral interpretations provided by
CGA on 29th March 2008. Block ordinary kriging was used to estimate copper and
density into a constrained cell model reflecting the interpreted
mineralization. Copper grades were capped at a maximum grade of 8.48 % copper
prior to estimation. No capping was applied to density. Search ellipse radii
and variogram ranges used in the estimation reflect the spatial continuity and
the observed mineralisation trends. Orientation of the search ellipse and
variograms was controlled locally using the orientation of the mineralisation
through the application of Datamine Studio's dynamic anisotropy method.
Estimates were placed into parent cells with dimensions of 5m x 10m x 10.
These parent cells were subdivided into sub cells of 2.5m x 5m x 1m for better
volume definition. Moisture content was not applicable as only dry mass was
considered.
    The model assumes open pit mining is possible for all the defined
resource. There will be a NI 43-101 technical report lodged for the resource
statement which will cover the key assumptions, parameters and methods used to
estimate the mineral resource.
    The mineralization envelopes were defined by geological interpretation at
a nominal cut-off grade of 0.1% Cu. The resource blocks contain significant
internal dilution. The global mineral resource estimates at a series of
cut- off grades are presented in Table 2.

    The mineral resource estimate based on a cut-off grade of 0.3 % copper is
18.5 Mt at a grade of 0.83 % copper, at a copper price of US$3.00/lb.

    Mineral resources that are not mineral reserves do not have demonstrated
economic viability. The study work to date does not show any indication that
the mineral resource would be materially affected by an known environmental,
permitting, legal, title, taxation, socio-political, marketing.
    Mining licence applications are in order and the Environmental Impact
Assessment has been completed and submitted. There are no indications from a
pre review of any environmental issues. Relocation of some Zambian locals, who
were given permission to reside within the farm lease, is covered within the
environmental issues previously raised by the government department. Liaison
with the local communities has been ongoing and the general response from the
community is that they welcome this project into an area which has no large
industry, only limited commercial farming and subsistence farming.
    Permission to draw water form the local river has been applied for and
has been given the full support of the ministry and the Lunsemfwa Hydro Power
Corporation Ltd who have water right boundaries covering the area in question.
    The site is easily accessed by the main northern highway (a sealed road)
from Lusaka to Kapiri Mposhi, where the main sealed highway to the northeast
and Tanzania is followed for 15 kilometers, at which point an existing gravel
road (30 km) leads to the project site. The site is at an altitude of 1100 m
ASL. Plentiful water and electrical power is available nearby. It is
approximately 123 km SSE of Ndola, the Copperbelt provincial centre, and some
45 km SW from the town of Mkushi. (Refer to Figure 2).

    There are two forms of power supply easily accessible in the area: Zesco
and the Lunsemfwa Hydro Power supply.

    The new taxation system announced earlier this year in Zambia has been
reviewed and at this stage does not negate the potential viability of the
project. This will however, be the subject of detail financial analysis later
on.
    Research into the marketing of the copper concentrate has strongly
indicated that off-take sales agreements would be negotiable within Zambia
itself. This has been supported following direct discussions with off-take
companies.
    Several significant assay results received since the current resource
estimate was made in March 2008 and these were not included in the estimate.
Some of these results relate to the close spaced vertical RC programme ("VRC")
drilled on a 10m x 10m grid at G Zone. These, along with other significant
recent diamond drill ("DD") and RC results can be seen in Table 3

    Metallurgical Testwork
    ----------------------
    Preliminary test work was conducted at AMMTEC Ltd at their Balcatta
facility in Western Australia. This test work was to establish the design
criteria for process and plant design. The results of the programme indicate a
potential 96% recovery of copper using conventional copper sulphide flotation
technology. The ore as tested does not have any significant levels of other
onerous minerals and thus would not likely to experience any smelter
penalties. The grade of the core samples sent for testing ranged between 0.77%
and 2.04%, with an estimated average of about 1.50% based on core assays.
Additional recent test work has subsequently confirmed the recovery of at
least 96%.
    The test work so far has shown that the process can provide for a
concentrate of 30% copper. This indicated that there is a potential for
economic extraction of the copper mineralization at the Mkushi Project.

    Reserve Calculation
    -------------------
    An optimisation of the resource model has been commenced by LQS, based on
economic and mining parameters currently available. It is anticipated that
these will be refined as additional supplier information becomes available. A
first-pass reserve calculation is currently expected in the next quarter.

    Licences
    --------
    The application for the mining licence was re-submitted on 1 May 2008,
when the Zambian government lifted its moratorium on new applications. On
26 June a "Notification of successful validation" was prepared which confirms
that the area applied for is 61.5 square kilometres. We duly acknowledged this
notification and now await the conditions and fees to be set during the next
phase of the approval process.

    General
    -------
    Discussions are in progress with the education department concerning the
relocation of the basic school and associated facilities, which are currently
situated close to the mine site. The relocation will provide an opportunity to
build improved facilities for the community.

    SEGILOLA PROJECT UPDATE
    -----------------------
    The two containers, holding the Turkish drill rig accessories and
consumables, supplied by Spektra Jeotek Sanayi Ve Ticaret A.S. ("Spektra),
were cleared by customs authorities in the first week of April. They were
transported to site where the Turkish drilling crew and supervisors offloaded,
assembled and commissioned the drill rig. The main drilling programme has now
commenced.
    Fugro Environmental Consultants have been approached in connection with
conducting an environmental baseline study, as required to be done on the
project site to meet statutory and technical obligations.
    Samples are now being sent regularly via DHL to the assay laboratories in
Accra, Ghana, for analysis. Several assay results have already been returned
and are presented in the tables and sections below.
    A qualified land surveyor is currently being sought in Nigeria to
complete surveys for both our requirements and governments.
    Compensation for the loss of farm crops and food gardens is ongoing to
enable drill pad clearance to continue in line with drilling requirements.

    Field Work
    ----------
    Drill pad construction and access track clearing in preparation for the
Spektra Drill Rig continued during the quarter, using manual labour to avoid
damage to cash crops planted in the area. A total of 17 drill pads were
constructed during the period, complementing those previously prepared, which
has enabled 25 diamond core drill holes to be completed. More drill pads are
being prepared for the existing proposed holes.

    Trench Results
    --------------
    No new trenches were done during the period. However, results have been
received from the trench samples sent to SGS Laboratories Services, Ghana, Ltd
("SGS"). Encouraging trench results received from trenches north of drill hole
G41 are:

    Trench 2260N 10m @ 9.96 g/t Au includes 4m @ 14.22 g/t Au
    Trench 22331N 6m @ 2.57 g/t Au

    These are depicted in Figure 3.

    More trench samples are yet to be assayed which are being kept in the
compound at Ilesha.
    Surveying of all trenches is being planned along with the survey of
existing infrastructure, drilled holes and planned holes. Work is currently
under way to clear collars and trenches in preparation for the survey team.

    Diamond Drilling
    ----------------
    Since April 2008, diamond drilling has been carried out on the project
site mainly by Spektra with a minor contribution from Tanylag Drilling Ltd,
Nigeria ("Tanylag"). Tanylag has recently obtained the appropriate equipment
required to carry out the drilling in a more efficient manner and their
progress has improved.
    Spektra has drilled approximately 1875m of diamond core from a total of
22 holes since the commencement of the main drilling campaign. We are now
seeing assay results returns from SGS Laboratories in Ghana.
    Table 4 shows the holes drilled and the assay values returned as of
23 June 2008. At that time there had been in excess of 1980m of diamond core
drilling completed, being the combined Spektra and Tanylag results.

    CORPORATE
    ---------
    During the quarter, the Board of CGA announced the issue of 950,000
employee options under the Employee Option Plan. The issue was made in
connection with a number of key appointments made to establish both the
development and operating team for the Masbate Gold Project. The options have
an expiry date of 31 March 2013 and an exercise price of A$1.80. 365,000
options were exercised during the quarter for total cash proceeds of A$236,750
and 625,000 warrants were exercised for cash proceeds of C$643,750. At 30 June
2008, the Company had 9,535,000 options and 5,625,000 outstanding warrants on
issue. The total issued capital of the Company as at 30 June 2008 was
233,201,976 fully paid ordinary shares.
    During the quarter, the Company completed a private placement of fully
paid ordinary shares raising gross proceeds of C$35m through the issue of
21,212,000 new shares at C$1.65 (approx A$1.74). The private placement was
marketed on a best efforts basis by way of brokered private placement with
Haywood Securities Inc. as agent (the "Agent"). For their services, the Agent
received an aggregate commission of 5.0% of the gross proceeds.

    Notes

    1   The quarterly report provides a basis for informing the market how
        the entity's activities have been financed for the past quarter and
        the effect on its cash position. An entity wanting to disclose
        additional information is encouraged to do so, in a note or notes
        attached to this report.

    2   The "Nature of interest" (items 6.1 and 6.2) includes options in
        respect of interests in mining tenements acquired, exercised or
        lapsed during the reporting period. If the entity is involved in a
        joint venture agreement and there are conditions precedent which will
        change its percentage interest in a mining tenement, it should
        disclose the change of percentage interest and conditions precedent
        in the list required for items 6.1 and 6.2.

    3   Issued and quoted securities The issue price and amount paid up is
        not required in items 7.1 and 7.3 for fully paid securities.

    4   The definitions in, and provisions of, AASB 1022: Accounting for
        Extractive Industries and AASB 1026: Statement of Cash Flows apply to
        this report.

    5   Accounting Standards ASX will accept, for example, the use of
        International Accounting Standards for foreign entities. If the
        standards used do not address a topic, the Australian standard on
        that topic (if any) must be complied with.
