BULK COMMODITIES

Sebuku Coal Mine, Indonesia Straits Asia Resources Ltd (SGX: SAR) 100% Coal Co-operation Contract

Sebuku produced and sold 531kt and 403kt respectively in the March 2009 quarter. As expected Sebuku mine s production was lower on a year-on-year basis, due to the mining constraints associated with the forestry boundary. Rainfall also had an impact on year on year production shortfalls with Q1 2008 having lower rainfall than Q1 2009.

The mine is developing a highwall for mud stabilisation to enable access to reserves pending the boundary decision. The project is progressing satisfactorily. The mining methods that have been deployed as a result have meant that costs at Sebuku have risen over 2008 levels.

Jembayan Coal Mine, Indonesia Straits Asia Resources Ltd (SGX:-SAR) 100%

Jembayan performed well for the reporting period, increasing its production on a year-on-year basis.

Total production from the mine for the March quarter was 1,251 kt with 1,249 kt of coal sold.

A reduction in fuel prices since Q3 2008 has helped the mine to maintain its costs at around 2008 levels, the benefit being offset by higher contractor costs and a slightly higher strip ratio.

The drilling programme continues and results will be announced at appropriate times.

Quarterly Activities Report, March 2009

March quarter production from the Tritton Copper Mine totalled 5,835 tonnes of copper in concentrate, an 11% decrease on the previous quarter. Ore mined was 216,009 tonnes at a grade of 2.76% Cu. Ore milled was 222,531 tonnes at a grade of 2.76% Cu. Total ore mined and milled achieved decreased over the previous quarter by 17.5% and 15.5% respectively.

The Tritton mine is expected to deliver production of around 2,100t to 2,200t of copper in concentrate per month. Site cash costs (excluding TC/RCs) decreased for the quarter to US$0.96 per pound Cu (from US$1.21/lb in the December quarter). The benefits of the cost cutting programmes and the suspension of the expansion mining activities in the northern ore bodies has flowed through to operating costs. Given the current market price volatility and the high TC/RC charges associated with the current off-take agreement, the company will continue to closely monitor the economic viability of the Tritton operation.

The expanded processing plant s availability, throughput and metallurgical results have improved during the March quarter. The processing plant s average throughput during March was 168 dry tonnes per hour, with name plate design throughput of 175 dry tonnes per hour exceeded on occasions during March. Metallurgical results of the expanded processing plant have exceeded expectations with average recoveries of above 94.5% recorded for the quarter. The processing plant is well positioned to exceed the 1.4 million ore tonnes treated per annum when required.

The copper cementation process has proved successful with a gradual increase in production being recorded. In the March quarter 215 wet tonnes of cement were produced.

Production from the Whim Creek Copper Mine totalled 2,389 tonnes of copper cathode produced. Crushing activities were finalised during the quarter bringing mining and crushing activities at Whim Creek to an end.

The numerous initiatives implemented in the prior quarter had a positive impact on the cashflow performance of the operation. The operation will continue to draw down copper inventory from the heap leach pads which will steadily decline over a 12 to 18 month period.

Costs for the operation continued to reduce with the impact of lower acid prices being realised in mid March. With the cessation of crushing, site manning numbers were further reduced.

Quarterly Activities Report, March 2009

Cash costs for the March quarter were US$2.69/lb up from the Dec Qtr. Included in the unit rate is a non cash component of US$1.23/lb that relates to the drawing down of stock from the inventory model and net realisable value adjustments. Revenue was positively impacted in March due to quotational period price adjustments. The operation is in a credit situation for copper sold in Q1 2009 which will be repaid over Q2 2009.

Hillgrove produced 344 tonnes of antimony in the March quarter (148 tonnes previous quarter). Whilst the process plant has successfully demonstrated the ability to produce high quality antimony metal, the commissioning process has highlighted a number of areas in the process plant that require reconfiguration and modification in order to enable commercial production levels to be achieved.

A Process Plant Optimisation Programme was developed in late December/ early January to deal with the changes and it is anticipated that the plant will now be fully operational by July 2009. The timeframe for completing the optimisation programme is largely due to the need to import new filters for the solid-liquid separation. Additional capital required for plant optimisation is approximately $5m to be spent by July 2009. Once steady state antimony production has been achieved, the operation will then commission the gold circuit.

Antimony sales increased to 316 tonnes with a high level of customer support and strong demand for future production.

The plant encountered a number of metallurgical issues during March which resulted in decreased gold recovery. The feed rate to the plant was reduced to minimise the impact of these losses. The metallurgical issues had been resolved by the end of the quarter with recoveries back at design.

Further delays in commissioning the Coal Fired Power Station (CFPS) meant that the anticipated cost savings for the quarter were not fully realised.

Unit cash costs reduced for the quarter but remain higher than expected. Primarily the reasons for the higher than expected costs are due to the higher power cost (delay in CFPS) and the recommencement of mining activities at the Tasat pit which required pre-development and re-establishment of support infrastructure. The average unit cash cost for the quarter was US$940 per ounce, down 8% from the previous quarter. Year to date cash cost are US$881 per ounce.

Considerable work was undertaken during the quarter to secure access to a large elluvial deposit. In early April a MOU was signed with the local government to access this ore supply. IMK will commence mining and processing of this ore in Q2 2009.

PROJECTS

Madagascan Coal Project Straits 35% Red Island Minerals

Phase 2 of the drilling programme at the Madagascar coal project, the drilling of the Sakamena tenements commenced in late March 2009. Commencement was delayed from the original January date due to the cyclonic events and political unrest that has occurred in Madagascar. The first part of the Sakamena drilling programme will be to drill 18 shallow holes along strike in a NE / SW direction, starting in the north, close to the southern end of Sakoa. To date six holes have been drilled and coal has been intersected.

The coal samples from Phase 1, the drilling of Sakoa, are being tested and the final results are imminent. Initial indications suggest that the results are in line with expectations and that Sakoa can produce a washed coal with a 70% yield at 25 MJ/kg (6000 Kcal/kg), 15% ash and less than 1% sulphur.

Coal Exploration, Brunei Straits Joint Venture 35%

Over the reporting period a number of meetings with Brunei government agencies were held to discuss the application for the Prospecting License and FEE (JV Partner) outlined the proposed future activities for exploration drilling in Brunei.

A number of discussions were held with potential drilling contractors seeking expressions of interest in assisting with the proposed drilling program.

Quarterly Activities Report, March 2009

SOUTH AUSTRALIA

Torrens EL3195 Straits earning 70%

Straits is exploring for iron-oxide copper-gold ( IOCG ) systems in the highly prospective Stuart Shelf region of South Australia (Torrens Project). The Torrens Joint Venture is between Argonaut Resources NL (ASX:ARE) and the company (Straits earning 70%). The Torrens Project is located near the eastern margin of South Australia s Gawler Craton region (Stuart Shelf), within 50 kilometres of Teck Cominco s Carapateena copper-gold discovery and 75 kilometres from BHP Billiton s Olympic Dam mine.

During the quarter, the joint venture closely monitored ongoing third-party legal proceedings which will affect the timing of further access negotiations.

The joint venture has maintained a constant presence at the Torrens site at the substantial campsite constructed by Straits on Andamooka Island (within the tenement) for the purpose of deep diamond drill programs and other associated exploration works.

CORPORATE

Cash At the end of March 2009, the Straits Group cash resources totalled A$315 million. This comprised A$15 million for the Group s operations in Australia, A$270 million cash resources within the Straits Asia Group and A$30 million attributable to the Straits Group s other activities.

Debt Straits is currently reviewing its long term debt financing requirements. The Company has repaid A$45 million of debt facilities (drawn to A$43 million at 31 March 2009) provided by the ANZ and Macquarie banks on completion of the PTT transaction (see below).

Strategic co-investment alliance with PTT Group of companies In March 2009 Straits announced the formation of a strategic alliance with Asian energy major, the PTT Group of companies (PTT), via the sale of a 60% interest in its wholly owned subsidiary, Straits Bulk and Industrial Pty Ltd (SBI) for up to US$335m in cash to a wholly owned subsidiary of PTT Public Company Limited (the Transaction). This transaction was completed on 28th April 2009.

SBI is the holding company for SRLs Brunei coal exploration interests, Madagascan coal exploration interests and for SRLs 47.1% shareholding in the SGX listed Indonesian coal company, Straits Asia Resources Limited (SGX: SAR). SRL has also transferred the Yannarie solar salt project and a team of coal executives headed by Martin Purvis to SBI as part of the Transaction.

PTT is a diversified energy group of companies engaged in oil and gas exploration and production, gas transmission and processing, energy trading and retail distribution segments and accounts for nearly 30% of Thailand s total market capitalisation on the Stock Exchange of Thailand.

Following the Transaction, Straits has transformed into a company with significant base metals leverage (particularly to copper), is in a very strong cash position, and still maintains exposure to bulk commodities through its remaining 40% interest in SBI.

9

Quarterly Activities Report, March 2009

The cash proceeds of the Transaction provide SRL with the necessary financial resources to pursue attractive opportunities in the current market. The SRL management team have a solid track record of seeking and applying capital and expertise to undervalued resource opportunities to generate superior returns and Straits intends to focus on this strategy more intently going forward.

The total cash consideration of up to US$335m (approximately A$500m, equivalent to approximately A$2.14 per SRL share) comprises an upfront payment of US$220m which has been paid on completion and a performance payment of up to US$115m payable post completion. The performance payment relates to certain matters in connection with reserve upgrades in relation to the mine located on Sebuku Island, South Kalimantan, Indonesia owned by SAR or as otherwise agreed between PTT and SRL. The performance payment is expected to be realised during 2009.

The Board of Directors of SRL is currently reviewing the funding requirements of SRL going forward and its strategy with respect to the use of the Transaction proceeds. Approximately one fifth of the total consideration received by SRL in relation to the Transaction will be returned to shareholders via two separate instalments. The Board of Directors will provide an update on any proposed return of capital to Shareholders at the appropriate time.

Convertible Note On January 30th 2009 Straits announced that it had completed a Convertible, Unsecured Note issue with Standard Chartered Private Equity Limited (SCPEL). SCPEL is the wholly owned direct equity arm of Standard Chartered Bank. The issue comprised a first tranche of A$48.6 million and a second tranche of $31.2 million which was approved by shareholders at a General Meeting on 20th April 2009.

The four year term notes have a face value of A$1.45, which represented a 53% premium over the closing price on 29th January and a coupon rate of 4% payable annually in arrears.

An alliance with SCPEL brings a number of benefits to the company including:

Further strengthening of the balance sheet that allows Straits to continue with its key development plans whilst working through a volatile phase in the market cycle. The addition of a supportive cornerstone investor on the share register. Additional input from a highly experienced and internationally active private equity team through Board representation.

The issue of the Notes introduces a stakeholder that understands and supports the Company s growth oriented outlook and strategy to continue to develop and realize undervalued resource assets. SRL and SCPEL are fundamentally aligned in respect of pursuing a strategy to maximise total shareholder returns over the medium to longer term

Hedging There was no commodity or currency hedging in place at 31 March 2009.
