The operation continued to improve during the quarter with a 54% increase in ore tonnes mined, a 3% increase in ore tonnes milled and an 8% increase in mill head grade. Plant throughput continued consistently above design capacity. The increase in grade reflected the drop in pioneering work and the increased ability for the mine to keep up with the plant, reducing the requirement for supplemental tonnages from lower grade stockpiles.

The improvement in the plant is however best demonstrated by the performance achieved in the month of March where 16,594 ounces were produced at a cash operating cost per ounce of $454.

Overall cash operating costs per tonne milled for the quarter was US$20.45 (US$18.19 Dec quarter) and were adversely affected by the shutdown costs associated with work completed on the crusher in January, the increase in grinding media being used and the relining work on the SAG mill in March.

Cash operating costs per ounce for the quarter were impacted by the planned shutdown costs for maintenance during the quarter and the temporary drop in recoveries due to higher than planned throughput. The use of lead nitrate was only introduced late in the quarter, so the positive impact on recoveries is only reflected to a very limited extent.

The average realised gold price during the quarter was US$1,010/oz (net of all hedges), with total proceeds from the sale of gold and silver of US$40.7M.


There were 0 Lost Time Injuries during the quarter. Training of staff concentrated on incident investigation, tag out procedures and risk assessment. The site Lost Time Injury frequency rate has reduced to 1.1, with the project now having achieved 175 LTI free days.

Mining and Geology

During the quarter, the total volume movement was 2,059,926 BCM (1,793,374 BCM in Dec quarter) contributing 1,220,980 tonnes (791,329 tonnes Dec quarter) of high grade ore and 593,160 tonnes (456,274 tonnes Dec quarter) of low grade ore being mined. The main production areas were HMB East, Montana, Main Vein, Colorado and Binstar pits. During the quarter access to the northern extremity of Colorado Pit and the uppermost benches of the 320 metre high hill was established for the earthmoving fleet. Mining has commenced on the northern end of Colorado and grade control of the remainder of the top benches of the deposit is well progressed.

With the commencement of mining in Colorado and Binstar and in preparation for the expansion of main vein, mining grade control requirements increased. An additional drill rig has commenced which has enabled the mine geology department to keep ahead of immediate production requirements. Furthermore a third multi-purpose rig has commenced to undertake waste dump sterilisation, resource step out and geotechnical drilling.


Mill throughput remained consistent with the previous quarter at 1,167,521 tonnes (1,132,361) whilst gold production improved by 11% to 40,535 ounces. The mill throughput was adversely impacted by a vibrating grizzly failure in January which masked the real improvements made through the circuit. In February an annualised throughput of 5.6 Mtpa was achieved. This achievement supports the planned ramp up in production to approximately 6.5 Mtpa on the expansion. It is clearly evident that the equipment installed in the plant is capable of materially higher throughputs than the 4mtpa nameplate capacity. A program of staged increases in throughput rates to test metallurgical impact and to debottleneck the circuit is underway.

Fresh ore was sourced from HMB East and Montana pits whilst oxide ore was mined from Main Vein and Binstar pits and the Dump 90 low grade dump.

Lead Nitrate Trial

A trial of lead nitrate addition to the leach circuit commenced in mid-March to test laboratory scale test work which indicates 5-7% higher and faster recovery of gold can be achieved for a given ore blend and throughput rate with the majority of this recovery coming from the first third of the leach train. As throughput rates in the plant are increased, this improvement in leach kinetics will be critical to maintain high gold recovery as residence time in the leach circuit reduces. The trial was very successful and confirmed the laboratory test work. Following the success of the trial, lead nitrate will continue to be added to the circuit and it is expected that improvements in recovery will be maintained in spite of reductions in residence time.

Community Relations

Implementation of the Social Development Management Plan agreed with the local communities and government continued to support and provide assistance in the areas of health, education, infrastructure and livelihood assistance. A review of performance against the 2009 plan was undertaken together with the presentation of the 2010 Plan to the communities, local and regional government representatives in a series of workshops in the impacted Barangays and Regional Government offices.


Filminera Resources Corporation was granted a new 52.3 square kilometre exploration permit. The permit is contiguous to the tenements currently being mined by the Masbate Gold Project. A US$10M exploration program has also been announced and is already underway with 55,000m of drilling and 15,000m of trenching planned to be carried out over the next 12 months.


Work continued on the preparation of a Feasibility Study based on the resources as reported in the December 2009 report. The following sections of the report have either been completed or will be completed shortly.

Geology and Reserves

The assessment prepared by Geoscience Field Surveys Pty Ltd and Odessa Resources is complete.

Mineable Reserves (Probable)

The open pit design, scheduled capital and operating cost have been prepared by CGA using budget earthmoving unit rate estimates provided by two experienced international mining contractors based in Lagos, Nigeria. An independent geotechnical engineer has visited the site and examined the diamond core and in situ structure and recommended input data for the open pit design.

Metallurgical Testwork

A composited sample of drill core from areas within the orebody selectively chosen so as to represent the run of mine grade it was prepared and sent to Ammtec laboratories in Perth. The purpose of the recent analysis is to ensure that the sampling and testwork previously carried out on individual samples from various mineralised intersections within the mineralisation truly represents the orebody and the plant design specifications.

The recent results from Ammtec clearly demonstrate that the physical characteristics and leach time allowances in the process plant design are appropriate. The metallurgical program and process plant flowsheet have been designed and approved by R.W. Bourne and Associates, Metallurgical Consultants.

Process Plant Flowsheet and Design

This is complete for a standard primary crusher, single stage Semi Autogenous ("SAG") grinding circuit followed by carbon in leach ("CIL") and gold recovery circuit. The design, capital cost and operating cost estimates have been completed by Sedgman Engineering, a Process Engineering Consultant based in Perth, Western Australia.

Tailings Storage and Fresh ("TSF") Water Supply Storage Dam ("WSD")

The design is complete and D.C. Cooper Consultants is presently calculating the columns of earth to be moved and the capital and operating cost estimates.

Environmental Impact Assessment ("EIA")

Fugro Nigeria Limited has submitted a draft report for the internal review. The review is complete and Fugro are presently compiling the final report for submission to the regulatory authorities for approval.

CGA has appointed Mr. Gavin Cooper, an experienced geologist with in excess of 20 years working in Africa, Rwanda, Mali, Namibia, Senegal etc, to be the Regional Manager West Africa, to manage the development work for the Segilola Project.


As at 31 March 2010, group available cash was US$75.3M (including the cash reserves of FRC) after having paid the fourth interest and principal repayment on the BNP arranged project finance facility for the Masbate Gold Project of US$4.1M. The outstanding project finance facility has now reduced to US$66.9M at 31 March 2010.

During the March quarter, the Company closed the placement of 39,100,000 shares at C$2.20 with clients of BMO Capital Markets and Haywood Securities Inc. The net funds received (after costs) was C$81.7M. The proceeds from the raising were used to repay early the $10M loan facility with Meridian Capital CIS Fund and Casten Holdings Limited and the $25M Senior Promissory Notes. The balance of the funds raised will be used to increase exploration activity at the Masbate Gold Project, including 55,000m of drilling and 15,000m of trenching in the next 12 months, progress the planned expansion of the plant at the Masbate Gold Project and general corporate purposes.

The Company issued a notice accelerating the expiry date of its outstanding Warrants to 5 February 2010. During the March quarter, 188,000 share options were exercised for gross proceeds of A$169,200 and 5,337,500 Warrants were exercised for gross proceeds of C$5,497,625.

At 31 March 2010, the Company had 12,002,000 options on issue. The total issued capital of the Company as at 31 March 2010 was 331,194,976 fully paid ordinary shares.

CGA entered into a strategic alliance with Sierra Mining Limited ("Sierra"), who hold prospective gold exploration interests in the Philippines. Projects include the property immediately adjacent to Medusa Mining Limited's (TSX:MLL) rich Co-0 gold mine (March quarter - average grade 20.6g/t and cash costs of US$180/oz) and other properties to the south of the world class King-king gold and copper deposit. This will leverage CGA's exploration expenditure and further capitalise on the success to date in the Philippines. CGA has agreed to subscribe for 11.8M new shares and 5.9M free attaching options, representing 10% of the issued capital of Sierra, investing A$708,000.


CGA is listed on both the Toronto Stock Exchange and the Australian Securities Exchange. The Masbate Gold Project is the largest gold project in the Philippines and was successfully developed with first gold poured on 12 May 2009. The project, which is currently ramping up to full production, has a total indicated resource base of 4.55M ounces, total inferred resource base of 3.22M ounces with a probable reserve of 3.03M ounces of gold. At steady state operations the project is forecast to produce over 200,000 ounces per annum.

The 4Mtpa plant was constructed by Leighton Contractors Asia Limited ("Leighton") without one lost time injury. The mining contract for the Masbate Gold Project has been awarded to Leighton, the largest mining contractor in the world. CGA is completing a scoping study for the expansion of the plant throughput at Masbate.

CGA has a disciplined acquisition program focused on acquiring new gold projects with a substantial initial resource with the capacity to grow materially and where the development and operational experience of CGA can be applied to enhance shareholder value.

    required for items 6.1 and 6.2.
