Owned by Stone Resources Australia Limited, it was in production from December 2009 to 2011.
History
Stone Resources Australia, as A1 Minerals, was formed in May 2002 and listed on the Australian Securities Exchange in December 2003. A1 Minerals Limited changed its name to Stone Resources Australia Limited on 30 November 2012. The BrightStar gold project was an asset of the company at the time of listing on the ASX.
The mine is located within an area subject to the Wongatha native title claim. The Wongatha group is a shareholder of Stone Resources. In exchange for the consent of the Wongatha people to any current or future mining tenements, Stone agreed to protect all aboriginal sites, offer training and employment and issue shares in the value of $220,000 to the Wongatha.
Stone expanded BrightStar by acquiring the historical Mikado Gold Mine (28°50'25.71"S 122°38'38.45"E) in July 2005 from Deep Yellow Limited, which had previously mined the deposit in 2004. The deposit had also been mined from 1900 to 1911, when 9,916 ounces of gold had been recovered.
In July 2008, Stone purchased a second-hand gold processing plant, which it relocated from Kalgoorlie to the Mikado mine site. In May 2009, Stone signed a $1.7 million contract for the refurbishment of the plant. In July 2009, the company received the necessary approvals from the state mining regulator for the mine project.
The expanded BrightStar project included a number of proposed and existing open pits. Stone planned to recommence mining the existing Alpha (Brightstar) and Beta (Mikado) pits, producing 30,000 ounces of gold per annum. New pits were proposed for Gamma, Delta, Epsilon, Zeta, Eta and Theta (in the Corktree Well and ing of Creation areas, north of Laverton).
Mining commenced in May 2010 with 2,700 ounces of gold produced for the second quarter of 2010.
The mine continuously underperformed after start up, staying below the targeted production of 2,500 ounces of gold per month, with a low point of just 702 ounces produced in April 2011. Stone went into a lengthy ASX trading halt in July 2011 during an attempt to secure more funding. In 2014 additional plant modifications were proposed to improve gold recovery.
