GMC acquired the Mt McClure Gold Mine, near Bronzewing, in September 1999 and integrating it in the later.〔(Acq. of Mt McClure gold operations/ass. tenement interests ) GCM ASX announcement, published: 6 September 1999, accessed: 14 February 2010〕 Normandy, in turn, was taken over by the Newmont Mining Corporation in February 2002.〔(View Project Owners: Jundee - Nimary ) accessed: 19 December 2009〕 From 1991 to 2004, the mine produced over 3.0 million ounces of gold from eleven open cut and three underground operations, with the last of the later having closed shortly before the sale of the mine to View Resources.〔 View Resources purchased the mine in July 2004 from Newmont for A$9.0 million, a package that also included the McClure mining operation, 8 km west of Bronzewing. The company initially placed the mine in care and maintenance and hoped to resume production in mid-2005.〔 It later deferred the start of production date, making the final payment to Newmont in regards to the Bronzewing purchase in July 2005. In October 2006, View announced it would redevelop the plant at Bronzewing and target a mid-2007 start date for production. The company resumed mining at Bronzewing from underground and open pit sources in April 2007.〔 On 17 May 2007, it announced its first gold pour at Bronzewing. It forecasted a mine life of 4.5 years at an annual production rate of 120,000 ounces of gold, hoping to extend these figures. Mining was carried out in two open pit locations, the Success and the Central Pit, and two underground declines, Discovery and Calista. On 6 February 2008, the directors of the company announced a production short fall, with only 6,500 ounces produced instead of the expected 10,000 for the January month. This was blamed on a grade short fall. As an immediate action, View suspended underground mining. View Resources Limited went into administration on 8 February 2008, ending all mining activities on site. Navigator Resources announced on 2 April 2009 that it intended to purchase the Bronzewing mine for A$9.55 million plus an $6.45 million environmental bond. Navigator planned to resume mining from open pit sources in January 2010.〔(BRONZEWING ACQUISITION TARGETS IMMINENT GOLD PRODUCTION ) Navigator website, published 2 April 2009, accessed: 15 December 2009〕 The acquisition of Bronzewing was completed on 1 October 2009 and Navigator set the date for first gold production to April 2010.〔(RENOUNCEABLE RIGHTS ISSUE SHORTFALL ) Navigator Resources ASX announcement, published: 11 December 2009, accessed: 15 December 2009〕 Shortly after, on 7 October, the administrators of View Resources Gold, Ferrier Hodgson, announced that the company will eventually go into liquidation. Navigator carried out its first gold pour at the mine on 21 April 2010.〔(First Gold Pour at Both Bronzewing and Leonora Gold Projects ) Navigator ASX announcement, published: 21 April 2010, accessed: 7 May 2010〕 The mine produced 11,409 ounces of gold for the financial year 2009-10, all from the final quarter of the year, with a production forecast of 101,000 ounces for the following year.〔(Quarterly report June 2010 ) Navigator ASX announcement, published: 26 July 2010, accessed: 29 July 2010〕 Ore shortfalls caused the mine to underperform in its first full year of operation, with only 75,000 ounces processed. Navigator was forced to cut back its production projection for 2011-12 to 75,000 to 80,000 ounces and to raise additional cash through a A$32.6 million renouncable rights issue.〔 On 28 March 2013 Navigator Resources, owner of the miner, went into administration, with an estimated debt of A$30 million. The reason for the failure of the Bronzewing project was seen in the low grades the mine produced and the high labour costs in Australia. Approximately 200 staff at the mine were laid off and mining operations were halted by the appointed administrator, Pitcher Partners.〔(Administrator questions Navigator Resources' model ) ''Australian Broadcasting Corporation'', published: 3 April 2013, accessed: 9 April 2013〕〔(Miner 'crushed by low grade and high costs' ) ''Australian Broadcasting Corporation'', published: 5 April 2013, accessed: 9 April 2013〕 On 7 January 2014 it was announced that the mine had been sold to Metaliko Resources for A$4.82 million.
