Production from Tritton Mines in the March quarter totalled 6,464 tonnes of copper – with 6,311 tonnes of contained copper in concentrate and 153 tonnes in copper cement. The quarter production maintained the minimum 25 Ktpa rate achieved in the previous quarter.
Processing
The Processing Plant continued to perform well during the period with mill recovery remaining high at 95.6%. The Plant continues to focus on de-bottlenecking and recovery enhancement projects.
Mining
Costs
Mining was maintained at a high rate during the quarter. The change to the new “bottom up” mining method at the Tritton mine continues successfully.
The transition to owner operator progressed on schedule during the quarter with the remaining personnel to transition over the coming quarter.
Site cash costs (excluding TC/RC’s) for the quarter increased to $US2.62/lb from US$2.06/lb. This was primarily due to expenses related to the transition to owner operated mining.

Mt Muro continued to ramp up its processing operations over the quarter going on to produce 7,272 oz Au and 157,299 oz Ag.
The operation continues to focus on the major development of the Serujan open pit which is progressing on schedule. The ramp up in production continues with forecast production in FY2012 of approximately 70 Koz AuEq.
Mt Muro remains a resource with significant upside and exploration potential. The increased resource base and recent drill results continue to underpin the very positive future outlook for Mt Muro. Drilling continues with 5 drill rigs. Planning and pit development continues to support a
medium term production rate well in excess of 100 k oz AuEq per annum.
Hillgrove Antimony/Gold Project, New South Wales
Production activities remain suspended at Hillgrove. Work continued on site to manage environmental and rehabilitation requirements (water treatment and stockpiles) and maintain operational equipment readiness. Gold and antimony prices remain high.
Straits continues to work with Court Resources to explore the potential to list Hillgrove as an independent antimony producer.

NEW SOUTH WALES
Tritton
Straits – 100%
The deep drill programme below the Tritton deposit continued during the quarter with a further six holes completed.
-
Drillhole TTDD027 (no significant result) targeted the southern side of the orebody and intersected a thin section of the Tritton mineralisation.
-
Drillholes TTDD023, 24 and 25 tested the thicker central area of the deposit. All holes intersected sulphide mineralisation between 41 to 49m in
thickness. Significant assay results are tabulated below.
- Drillhole TTDD026 was drilled into the northern limb of the Tritton deposit. The hole intersected 17m of significant sulphide mineralisation.
Drilling will continue into the first quarter of FY 2012, to prove up reserves, aiming for an 8 year minimum mine life for Tritton.

Torrens EL4296: Straits – earning 70%
The Torrens Joint Venture (Torrens EL 4296) is between Argonaut Resources NL (ASX:ARE) and Straits Resources Limited (Straits earning a 70% interest).
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 Carrapateena copper ‐ gold discovery and 75 kilometres from BHP Billiton’s Olympic Dam mine.
In early July 2010 the Torrens Joint Venture announced that its application under Section 23 of the Aboriginal Heritage Act 1988 in South Australia in respect of the Torrens Project (EL4296) had been approved by the Minister for Aboriginal Affairs and Reconciliation. A judicial review of this decision was dismissed on 17 March 2011 in the Supreme Court of South Australia (Justice Sulan), ensuring that the original Section 23 authorisation stands
The Torrens JV partners are in the process of appealing the ERD Court decision (Justice Tilmouth). The parties to the Torrens Joint Venture have been granted leave to appeal the ERD Court determination in the full court of the Supreme Court. A date for the hearing is expected for September or October 2011.
Stuart Shelf Joint Venture: Straits – earning 70%
The Stuart Shelf Joint Venture is between UXA Resources Limited (ASX:UXA) and Straits Resources Limited (Straits earning a 70% interest). The joint venture includes 9 tenements for a total of 3,300km[2] .
Geophysical evaluation of the highest priority targets within the tenement package is now complete and heritage surveys are expected to be undertaken during the coming quarter. Delays have been experienced with the granting of leases by the SA department in addition to the

Straits – 100%
An updated resource estimation for the Serujan and Bantian was completed during the reporting period with an additional 157K AuEq ounces added to the resource inventory (see ASX:SRQ announcement dated 12 July 2011). Exploration continued to produce encouraging ore grade intersections during the quarter from the Serujan and Bantian project areas.
Three diamond rigs continued drilling at Serujan, testing the area between the Serujan Central and Serujan East pits. Drilling has successfully linked the structures between these two pits into one continuous mineralised structural corridor. Drilling continues to intersect mineralisation outside the existing resource models and pit designs.

Corporate
Cash & Debt
At the end of June 2011, the Straits Group cash resources totalled A$47.4 million (includes US$16.3m). Of this, approximately A$11 million is restricted cash.
Straits has investments of approximately A$26 million in listed companies excluding Goldminco.
At the end of the June 2011 quarter, Straits debt comprised a trade finance facility of US$30 million debt within Magontec, which is backed by receivables, and Tritton hire purchase for mining fleet A$18 million.
Goldminco
Corporation (TSX-V: GCP) (“Goldminco”) that it does not already own at an offer price of Cdn$0.10 in cash per share. Full details of the offer were included a formal offer and take-over bid circular (the “Circular”) which was mailed to Goldminco shareholders on 7 June 2011.
On 5 July 2011 an independent committee of Goldminco Directors unanimously recommended that Goldminco shareholders accept the offer.
On 14 July 2011 Straits announced that it had acquired 97.5% of the issued and outstanding shares in Goldminco.
The offer has been extended until 25 July 2011.

Magontec
Post the June quarter end Straits announced that it has entered into an agreement to divestiture Magontec to Advanced Magnesium Limited (AML – ASX Code: ANM) a leading magnesium alloy manufacturer.
The sale of Magontec continues to simplify the Straits structure, allowing the company to focus on its copper and gold assets. The sale has also simplified the Straits balance sheet by removing approximately US$16 million of debt as at 30[th] June 2011.
Hedging
The total consideration for the sale was US$6 million payable to Straits as a combination of equity and a convertible note in AML. Existing shareholder loans of $12.8 million remain on foot and repayable to Straits over three years.
The combination of the magnesium companies is seen as extremely positive for Straits, Magontec and AML, with the transaction producing a vertically integrated magnesium alloy manufacturing and technology business.
There are forward exchange hedges in place at 30 June 2011 totalling US$57 million for settlement from July 2011 through to December 2011. Currency hedging is at an average US$/A$=0.9996. These FX forward were put in place to lock in the A$ receipts forecast to be received from copper shipments over this period. At 30[th] June copper pricing has been fixed with the off take partner for four shipments, totalling 9,600t, between now and December 2011 at an average price of US$9,416/t.
