The Marvel Loch Gold Mine is a gold mine located at Marvel Loch, 30 km south of Southern Cross, Western Australia. It is operated by St Barbara Limited.〔(St Barbara website - Southern Cross ) accessed: 3 September 2009〕 Apart from Marvel Loch, St Barbara also operates the Gwalia Gold Mine at Leonora and owns the Tarmoola Gold Mine, which is placed in care and maintenance.〔(St Barbara website - Leonora ) accessed: 3 September 2009〕〔(St Barbara website - Operations overview ) accessed: 3 September 2009〕 All three mines were previously owned by the now defunct mining company Sons of Gwalia Limited.〔''The Australian Mines Handbook: 2003-2004 Edition'', page 520〕 Sons of Gwalia went into administration on 30 August 2004 and the company's gold mining operations were sold to St Barbara in March 2005 for A$38 million, having been valued by the Sons of Gwalia directors at A$120 million. While Marvel Loch was operational before and after the sale, the Gwalia mine was already placed in care & maintenance at the time of the transaction. A fourth mine, the Carosue Dam Gold Mine, ceased operation in June 2005 and has since been sold by St Barbara.〔(Sons of Gwalia Limited at delisted.com.au ) accessed: 3 September 2009〕〔(St Barbara Mines Limited - Lodgment of Open Briefing ) published: 28 June 2005, accessed: 3 September 2009〕〔(''The West Australian'' ), published 16 March 2005, accessed: 3 September 2009〕 ==History== Mining in the area around Marvel Loch dates back to the early 1900s and between 1905 and 1986, 136,300 ounces of gold were recorded as having been mined.〔''The Australian Mines Handbook: 2003-2004 Edition'', page 107〕 From 1979 to 1987, the mine was operated as a joint venture between Kia Ora Gold Corporation NL and Western United Limited, after which it was sold to Mawson Pacific Limited. Mawson Pacific subsequently sold the mine to Reynolds Australia Gold Operations Ltd, a wholly owned subsidiary of Reynolds US Metals. During its period of ownership Reynolds acquired the Southern Cross Mill and adjacent tenements including the Transvaal Underground Mine and the Cornishman Open Pit (a 50/50 joint venture with Troy Resources NL)located approximately 25km north of Marvel Loch. On 1 April 2005 the Marvel Loch Mine together with the Southern Cross Mill and adjacent mines was sold to Sons of Gwalia for $23m. During 1995 and 1996 Sons of Gwalia acquired Orion Gold NL and Gasgoyne Gold Mines NL whom together owned the Yilgarn Star Joint Venture approximately 16km south of Marvel Loch. The Yilgarn Star Joint Venture operated the Yilgarn Star Open Pit and Underground mine and mill as well as the Nevoria Gold Mine. Sons of Gwalia mined the Marvel Loch deposit as a surface mine for the most part of the mine's history since reopening in the 1990s, upgrading its production facility in 2001.〔 In February 2001, the company announced it consolidated its Southern Cross operations, acquiring the remaining 30% of the Yilgarn Star Gold Mine it didn't own and merging the operation with Marvel Loch, closing the Yilgarn Star mill. It also acquired other interests in the region in this transaction.〔(Rationalisation of Southern Cross Region of WA ) SGW ASX announcement, published: 7 February 2001, accessed: 8 February 2010〕〔(Media Release: Highlights from Quarterly Report 30-6-98 ) SGW ASX announcement, published: 17 July 1998, accessed: 8 February 2010〕 Since then, production from Yilgarn has been listed under Marvel Loch.〔''The Australian Mines Handbook: 2003-2004 Edition'', page 137〕 After a rapid rise of the company, unauthorised gold and foreign exchange trading activities by chief financial officer Eardley Ross-Adjie in the year to June 2000, ended up costing Sons of Gwalia more than A$190 million.〔(How sons of Lalor built, then sank, Sons of Gwalia ) The Sydney Morning Herald, accessed: 4 September 2009〕 Sons of Gwalia went into administration on 30 August 2004, following a financial collapse, with debts exceeding $800 million after suffering from falling gold reserves and hedging losses.〔(Ernst &Young agrees to $125m Sons of Gwalia settlement ) The West Australian, published: 4 September 2009, accessed: 4 September 2009〕 Sons of Gwalia was Australia's third-largest gold producer and also controlled more than half the world's production of tantalum.〔(Sons of Gwalia's gold hedging had big holes ) The Sydney Morning Herald, published: 4 September 2004, accessed: 4 September 2009〕 St Barbara purchased the mine from insolvent Sons of Gwalia in March 2005.〔(St Barbara Mines Limited - Lodgement of Open Briefing ) published: 28 June 2005, accessed: 3 September 2009〕 Since the purchase of the Mine by St Barbara, mining has been carried out both in surface and underground operations.
