Mandalay Resources Corporation reports production and sales for the second quarter of 2013 and improves 2013 full-year guidance

TORONTO, July 10, 2013 /CNW/ - Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND) announced today its production and sales results for the second quarter of 2013.

Brad Mills, Chief Executive Officer of Mandalay, commented, "Mandalay delivered strong operating performance in the second quarter of 2013. Both Costerfield and Cerro Bayo produced and sold record amounts of gold during the period, and Cerro Bayo produced record amounts of silver. Costerfield generated its third highest antimony production quarter ever. As expected, Cerro Bayo's record second quarter performance made up for lower production in the first quarter, which was related to the planned curtailment of plant operations during installation and commissioning of flotation automation equipment."

Mr. Mills continued, "Our performance in the first two quarters of 2013 and operating commitments for the balance of the year allow us confidence that full-year production will be at the upper end of our previously announced production guidance ranges of 16,000 - 21,000 ounces gold and 2.8 - 3.1 million ounces silver from Cerro Bayo and 2,800 - 3,000 tonnes antimony from Costerfield.  At this time, we are pleased to raise our guidance for gold production from Costerfield from the previous 18,000 - 21,000 ounces to 20,000 - 25,000 ounces for the full year 2013. This is based on our experience with higher than planned mill feed gold grade and our growing confidence at being able to extract and sell a significant amount of coarse gold in gravity concentrate while maintaining high gold grades in our flotation concentrate. We expect to complete a Preliminary Economic Analysis on a new Life of Mine Plan for Costerfield, including the Cuffley lode, in the third quarter of 2013 and will make a development decision regarding Cuffley based on that analysis. We also anticipate releasing exploration updates from Costerfield and Cerro Bayo during the third quarter of 2013."

Saleable production for the three months ended June 30, 2013:

• The Company's saleable production totaled 13,046 ounces ("oz") gold ("Au"), 738 tonnes ("t") antimony ("Sb"), and 921,895 oz silver ("Ag"), representing a total of 33,558 oz gold equivalent ("Au Eq.") production. Au, Ag, and Au Eq. production amounts set new quarterly records for Mandalay.
