SIMBERI OXIDE GOLD PROJECT - OPERATIONS
During the March 2009 quarter management was primarily focussed on two key aspects of the gold operations. The first was to reduce the Gold in Circuit (GIC) from the approximately 8,500oz that resided at 31 December 2008 to a targeted level of below 4,000oz. This process continues and required a conscious slowing down of the processing plant to ensure the applicable levels of extraction were achieved.
The second area of focus was to ensure a consistent production profile which would be further analysed to assess mine planning initiatives as well as identify the capital expenditure priorities over the coming months to ensure continuing improvements in production.
Despite the excessive levels of rainfall experienced during the quarter and the operational challenges this provided, Allied Gold managed to sustain a base line level of gold production of 17,510z for the March quarter.
The conscious approach to reducing the GIC resulted in a record for gold sales for the quarter with 23,391oz sold at an average price of A$1,253 p/oz. Group cash flow from operations resulting from this successful operational initiative was in excess of A$9.5M for the quarter.
Therefore for the March 2009 quarter mining volumes decreased by around 20%. At the start of the March quarter the Company had in excess of 70,000 tonnes of ROM ore stockpiled at the Pigiput processing facility to mitigate the traditional wet season. During the quarter the stock pile was drawn on to ensure consistent production continued.
Cash costs increased slightly during the quarter as a direct result of the lower production volumes. The overall impact of the lost production in tonnage over the quarter resulting from rainfall was approximately 80,000 tonnes. This equates to approximately 3,210oz for the quarter.
Over the course of the year Allied Gold has experienced a significant strengthening of the AUD/PGK currency which has impacted the year to date cash cost budgeted targets. With now approximately 40% of costs being denominated in PGK including fuel the currency impact is becoming a greater concern and Management is in the process of assessing a number of FX hedging strategies to ensure the PGK cost base is appropriately managed.
Processing plant performance was fundamentally in line with the previous quarter's performance however the excessive rainfall during the quarter inhibited the plants ability to steadily increase its processing volumes as initially scheduled.

During the quarter Allied Gold successfully completed a capital raising at A$0.50 per share which generated approximately A$30.7M. The placement was announced on 24 February 2008 and was oversubscribed. The placement introduced a number of new institutional shareholders to the register as well as strong support from existing shareholders.
The Board was pleased to announce the appointment of Monty House to the Board of Allied Gold as an independent non-executive Director. Mr House's experience and background will significantly strengthen the Board of Allied Gold Limited and its current Corporate Governance Structure.
In accordance with the contract dispute processes that exist between Allied Gold and the mine construction EPCM contractor Intermet (now owned by Sedgman Limited), Allied Gold is in the process of issuing a Default Notice which allows the Company to officially take control of legitimately rectifying numerous deficiency notices issued by Allied Gold.
Allied Gold has appointed a legal firm to pursue Intermet for specific performance and damages relating to the EPCM contract along with additional legal actions against the former proprietors of Intermet for false and misleading representations and conduct under the Trade Practices Act.
Allied Gold had accrued all outstanding amounts under the original contract within its 30 June 2008 Financial Statements. The Company will keep the market informed of any subsequent events as they arise.
CASH AND DEBT
Allied Gold retired the original Simberi project financing facility during the March quarter. The original 4 (four) year USD$25M facility was drawn to USD$19.6M during the construction phase of the project and has been repaid approximately 21 months ahead of schedule.
Cash flow from operations was positive for the March quarter with a record 23,391oz sold for the period. Group cash flow was in excess of A$9.5M for the quarter. During the quarter in excess of A$18.0M was spent on investing activities such as exploration and capital expenditure as well as a further A$4.0M incurred on the final debt repayment of the existing debt facility.
The cash expenditure on the investing activities is in line with the Company's approach of significant reinvestment into the project and Company. As of 31 March 2009 Allied Gold Limited had cash at bank of A$29.9M.
GOLD AND HEDGING
At the end of the March 2009 quarter Allied Gold successfully restructured its hedge book reducing the overall duration by approximately 12 months. The restructure did not require any cash outlay for its successful execution.
On an annualised basis the company now has less than one year's production as committed hedging. Allied Gold continues to assess and manage its position to ensure significant gold price participation is maintained.
Below is a summary of the revised hedge book position. As at 31 March 2009 the mark to market of the hedge book was approximately (US$11M).

PROJECT DEVELOPMENT
SULPHIDE PROJECT - SULPHIDE STUDY
Management commenced a formal study into the potential development of the Simberi sulphides and, in particular, the Pigiput Sulphides.
As the table below indicates the total Measured, Indicated and Inferred sulphide resource is approximately 1.9 million ounces of gold. The largest sulphide resource is located at Sorowar, adjacent to and below the largest oxide deposit.
The Pigiput Ridge area contains the highest grade sulphide resource (refer table and figure below) and has been subjected to a reasonable amount of exploration drilling.

The sulphide development program in 2009 will mainly consist of technical studies focussed on sulphide metallurgy and mineralogy to determine appropriate ore treatment options and process routes. The program commenced with the engaging of a mineral processing engineering firm and a metallurgical consultant.
The engineering was awarded to GR Engineering Services (GRES) from Perth, and Battery Limits, also a Perth based firm, have been appointed as the owner's metallurgical representatives for the project. It is proposed to deliver a Pre- Feasibility Study (PFS) by the end of the year and this study will be managed by GRES.
Prior to commencing the PFS the Company has completed a Scoping Study in this current quarter, which is a high level desk top study based on existing information and has focused on reviewing available gold sulphide treatment technologies and defining the risks and opportunities of a Simberi sulphide operation. The study was based on 1Mtpa process facility to produce 80,000 to 100,000 ounces of gold per annum.
The scoping study has identified several potential development opportunities via process routes that include marketing a concentrate, heap leaching a concentrate on site to produce gold, and possible roasting of a concentrate to produce gold on site. Other process that were investigated but rejected because of capital and or operating cost, and technical risk included, pressure oxidation (autoclaving); fine grinding of concentrate and atmospheric leach ; ultra fine grinding of concentrates with low pressure oxidation ; and tank leaching of concentrates using bacterial oxidation.
Producing gold on site via heap leaching or roasting requires cyanidation of the leachate or oxidised sulphide and this would require expansion of the existing CIL oxide process facility. Such an expansion could provide more immediate additional opportunity to process additional oxide ores at a lower cut-off grade commensurate with the current high gold price.
The study going forward will focus on the three potential process options commencing with stage 1 metallurgical testwork. This laboratory test work will be carried out by Ammtec in Perth under the management of Battery Limits and in collaboration with GRES and will focus initially on optimising concentrate production via conventional flotation. Stage 2 testwork will look at the other possible process options of oxidation via heap leaching, and oxidation by roasting.
Concurrently metallurgical, infill and extension drilling will be carried out at Pigiput and will involve initially approximately 12,000 metres of combined RC and diamond coring.
EXPLORATION
SIMBERI GOLD RESOURCES
PIGIPUT OXIDES
A resource estimate carried out by Golder Associates for the Pigiput East oxides was released in November 2008 and also reported in the December 2008 quarterly release. This release stated an additional 204,000 Inferred and Indicated Resource gold ounces resulting in total Pigiput oxide Indicated and Inferred Resources of 293,000 ounces of gold.
Subsequently in March 2009, Golders carried out a new oxide mineral resource estimate for the Pigiput oxides using 5,733 metres of sampling from 33 RC and 8 diamond cored holes that were drilled post November 2008. This new estimate has actually resulted in a reduction in the resource estimate by 27,000 ounces resulting in a net total Indicated and Inferred resource of 266,000 ounces.
Although additional drill data was added the reduction in metal was due to an anomaly in the mineral resource model where some mineralised blocks had incorrect bulk densities assigned. A correction of the densities has resulted in a decrease in tonnage which has translated into a reduction in the resources gold ounces. This new estimate is compared with the previous November 2008 results in the table below

PIGIPUT SULPHIDES
Drilling at Pigiput targeting the extensions of sulphides continues to define additional mineralisation. Three diamond cored holes for 920 metres that targeted down dip mineralisation (Pigiput Deeps) were completed during the quarter. Refer to the exploration section for details on gold intercepts. These holes intersected broad down hole zones of gold mineralisation as indicated below.

In addition, two of five planned diamond cored metallurgical holes, for a total 407 metres, were also completed. The core from the first hole was delivered to a metallurgical laboratory in Perth.
SIMBERI EXPLORATION - ML 136
A planned 9 hole / 3000 m core drilling program commenced, testing the down dip extension of the Pigiput Prospect gold mineralization, the Pigipit Deeps. Four holes, SDH017 to SDH019 and SDH021 were completed, since start-up in December 2008. A second core drilling rig is being commissioned, to assist with this program and the metallurgical sampling (SDH022 completed) required for the Pigiput Sulphide Scoping Study.
The Pigiput Deeps program will test a 200 m wide area up to 350 m down plunge of a conceptual pit-shell presently being used in the scoping study. Earlier wide-spaced drilling in the area intersected broad zones of mineralization, including previously reported 95.7 m @ 1.79 g/t from 83.3 m in core hole SDH011. Three of the holes completed exceed 350m length and, as such, form part of a deep drilling program required to be done on Simberi Island by the Allied Gold - Barrick Gold Joint Venture agreement.
Exploration drilling is also underway on the adjacent Pigibo Prospect, targeting gold mineralization in oxide. Wide-spaced earlier drilling was used to estimate a previously published Inferred Resource, of 2.1Mt @ 1.1g/t for 74,000oz, largely in oxide. Of a planned initial 42 hole / 5,040 m programme, 11 RC percussion holes totalling 1,205 m are drilled.
Hole RC1772 was a 34m partial twin of RC1771 that had suffered poor recoveries in the first 15m of the hole.
Assay results are available for all 11 holes and the better intercepts, defined using the same 1.0 g/t assay cut-off procedure as defined above, are tabled below:

NOTE: Down hole intercepts in table 2 & 3 are determined using a cut-off of 1.0g/t Au and may include intervals of material below the cut-off, but no more than 2 sequential meters of such material, except where the average drops below the cutoff. Selvage is only included where its average grade exceeds 1.0g/t.
Assay limit of detection for gold at ALS is interval length, resulting in any included core loss being assigned zero grade.
Duplicates, inserted for QC purposes, are not averaged. Supplementary cutoffs are used to highlight higher grade zones and spikes. Single assays intervals are reported only where >2.5g/t and >1m down hole.
The Ag grade is average for the same metre intervals as defined by the Au intercepts. The Ag detection limit is 0.2g/t, and is derived from a 0.5g charge Aqua Regia digest, with assay via ICP AES.
The Pigibo Oxide drilling programme will continue into the June 2009 quarter as part of the overall Allied Gold exploration strategy.
TATAU AND BIG TABAR ISLANDS - EL609
Under the terms of the Tabar-Tatau Joint Venture, Barrick Gold explored within the area of Allied Gold's EL609 on the Big Tabar and Tatu Islands. Barrick's activities during the quarter comprised:
completion of planned drilling at the Tupinda prospect, Big Tabar (982m DD);
commencement of drilling at the Banessa prospect, Big Tabar (1040m DD)
mapping and rock chip sampling over Tatau Island (447 samples); and
completion of a Heli-EM survey.
TUPINDA PROSPECT
Two holes, TPD003 and TPD004 for 982m DD, were completed at the Tupinda prospect during the quarter. Barrick's drilling, now four holes totalling 1,927m DD, has tested an alteration footprint within the Tupinda Intrusion Complex, interpreted as the best based upon magnetic signature, IP geophysics, alteration zonation and combined Cu and Mo geochemistry.
Assays were received for parts of TPD001 and TPD004 (21% of assays received). The best intercept to was 68m grading 0.05 g/t Au, 0.15% Cu, and 0.022% Mo (TPD001 from 209-277m), containing a better grade section grading 0.42% Cu over 7.00m.

TPD004 (655.6m) tested a combined Cu-Mo in soil anomaly and an IP anomaly. The dominant lithology comprises altered monzodiorite porphyries that are cut by post-mineral intrusion breccias and post-mineral dykes. Hydrothermal alteration within the monzodiorite is zoned downhole, with magnetite-pyrite dominant in the upper zone and dominantly potassic alteration in the lower zones.
Pyrite is the dominant sulphide in the upper magnetite rich alteration zone. Downhole, minor chalcopyrite with trace molybdenite occurs as discontinuous fracture fill in the potassic zone, and then bornite-chalcopyrite as fracture fill and occasionally as disseminations.
BANESSA PROSPECT
Drilling at the Banessa Prospect commenced in early March, with a total of 1040m completed to date. Two drill holes (BND002, 521m & BND003, 164m) were completed and two (BND004, 172m & BND005, 183m) were in progress at month end. The drill sites are targeting the potassic alteration zone at the northern end of the prospect, the magnetite vein zone and the combined gold and copper geochemistry.
BND002 (521m) intersected moderate to strong potassic alteration and localized calc-potassic alteration within breccia zones. Two lithological units, fine-grained diorite porphyry (possibly a syn-mineralization intrusion) and a pyroxene ± hornblende porphyry locally contain weak Cu mineralization over tens of meters with smaller zones, a few meters wide, containing up to 1% chalcopyrite. Mineralization is characterized by fine-grained chalcopyrite disseminations and is generally associated with magnetite and K-feldspar veins within potassic altered zones.
BND003 (164m) intersected both polymictic (and monomictic) intrusion breccias composed of diorite to monzodiorite fragments and possibly late commonly feldspar bearing porphyritic dykes or sills. The former commonly contain moderate to strong pyrite + sericite alteration and local remnant magnetite veining. The strong sericite pyrite alteration may reflect hydrothermal activity along a mapped southeast-trending phyllic altered structure nearby.
BND004 (172m in progress) has intersected a series of relatively thin porphyritic intrusive bodies and polymictic intrusion breccias that commonly contain sericite and pyrite alteration assemblages that change to dominantly chlorite from 197 to 212m. Locally, magnetite replacement of mafic phenocrysts and rare, possibly secondary biotite was observed.
BND005 (183m in progress) has intersected 22 m (true width 7m?) of oxidized Cu +/- Au porphyry style mineralization from 98 to 120m depth. Mineralization includes 2 to 8mm thick chalcocite or tenorite veins and breccia infill, chrysocolla vein halos and minor covellite.
TATAU ISLAND
Alteration, lithological and structural mapping of Tatau Island was undertaken during the quarter, in conjunction with rock chip sampling (447 rock chip samples collected). Mapping covered parts of the Kupo and Daramba prospects, and the logging road network in the vicinity of Kupo.
The objective of the mapping is to identifying potential porphyry Cu-Au centres through evaluation of historic mineralized centres and island-scale alteration mapping, prospecting and sampling. To date, the mapping has confirmed the dominance of monzodioritic to diorite stocks over the Daramba and Kupo areas. Propylitic (chlorite-pyrite-epidote) alteration is the predominant alteration style, with limited zones of structurally controlled potassic alteration identified at Kupo. Compilation of the mapping is ongoing.
An intense phase of geochemical sampling wa s conducted that focussed on systematic outcrop sampling along logging roads that have not seen previous work. Workers sampled outcrops at 25-50m spacing (dependant on outcrop) to rapidly cover a large area. The samples have been delivered to the lab and assays are pending.
TABAR-TATAU ISLANDS - HELICOPTER EM
Helicopter EM survey acquisition was completed on the Tabar Is lands. The data has been received and is undergoing QA/QC, with final results and images expected in the coming quarter.
OUTLOOK
Despite the abnormally high rain fall during the March 2009 quarter, Allied Gold production remained consistent further validating that 13 months since the first gold pour the production profile is closer to reaching a steady state.
Better throughput rates have occurred in the early part of April and as a result production is expected to return to levels more consistent with those experienced in the December 2008 quarter. As part of an overall scheduled maintenance program as well as the scheduled installation of an oversized scats crushing circuit, a number of production days will be lost during the quarter. It is therefore envisaged that production for the June quarter be in the range of 17,000 - 20,000oz depending on the maintenance schedule. Gold sales should correlate to these similar levels for the quarter.
The scats crusher will enable a more efficient processing of harder oxide and some transitional & sulphide ore within the existing pits. Also during the quarter, an extensive review of existing mine planning initiatives are being undertaken to ensure adequate pit access for scenarios where unseasonal high rainfall is experienced.
The Company continues to focus its efforts on achieving a consistent production profile while further optimising the plant performance. Management continues to focus its efforts on reducing operating cash costs as the plant progresses to a steady state operation. Management is optimistically confident that nameplate can be consistently achieved during the June 2009 quarter.
During the June quarter scoping studies regarding power generation efficiencies and reagent usage continuing. To facilitate this process a number of small planned shutdowns are scheduled throughout the June quarter.
It is anticipated that during the June quarter the Company will commence its own aircraft charter service between Australia and PNG thereby significantly reducing its travel expenditure and increase exiting levels of productivity as a result.
The focus on accelerating exploration activities continues to progress. A fifth drilling rig was mobilised to site in the March quarter to help accelerate exploration programs on Simberi, particularly the infill and extension drilling at Pigiput. The objective is to acquire sufficient data to allow for a new resource estimate be made during the September 2009 quarter to form part of the Sulphide Development program. During the June quarter, Management will review and allocate a level of resources commensurate with the accelerated exploration plan.
Barrick continue to drill on the neighbouring island of Tabar with additional assayed results expected during the June quarter. As these results become available, management will ensure the results are communicated accordingly.
Progress is expected with the Sulphide Expansion Project pre PFS enabling Management to eliminate certain potential options and choose the most efficient process for further assessment.
As an investment sector gold remains a strong thematic within the global financial and investment sectors Allied Gold is one of the few emerging gold producing companies that possess significant exploration potential as well as track record in delivering projects in challenging operating environments.
Allied Gold continues to assess existing emerging opportunities within the sector that may ultimately complement its existing strong organic growth profile. Allied Gold has a number of internal metrics it applies to potential opportunities to ensure a disciplined approach to identifying and assessing various potential opportunities.
Nonetheless Management's primary focus remains the achievement of a steady-state operation at the Simberi Island gold project and continuing to monitor operating costs with a view to reducing the bottom line cash costs per ounce of gold.

Glossary of terms used in the Announcement:
19. A 'Mineral Resource' is a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form, quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
20. An 'Inferred Mineral Resource' is that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability.
21. An 'Indicated Mineral Resource' is that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.
22. A 'Measured Mineral Resource' is that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are spaced closely enough to confirm geological and grade continuity.
