TORONTO, April 18, 2013 /PRNewswire/ --

Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND) announced today its production and sales results for the first quarter, 2013.

Brad Mills, Chief Executive Officer of Mandalay, commented: "Mandalay's production and sales for the first quarter were in line with our expectations. Costerfield delivered another strong performance, continuing the trend of improvement of the last few quarters by achieving record gold production and near-record antimony production.  This high level of production is expected to continue as the operation continues to ramp up production on N-Lode and begins development of the Cuffley Lode. As planned and previously announced, Cerro Bayo delivered lower production than the prior quarter as plant operating time was restricted due to the installation and commissioning of flotation automation equipment that is designed to improve recoveries of both gold and silver. In addition, lower grade ore was fed through the plant as part of the commissioning program for this new equipment. We expect ore grades to improve, along with recoveries, in the next three quarters and we expect to deliver the full 2013 production guidance over the course of the year."

Saleable Production for the three months ended March 31, 2013:

• The Company produced a total of 10,635 ounces ("oz") gold ("Au"), 766 tonnes ("t") antimony ("Sb") and 611,441 oz silver ("Ag"), representing a total of 27,128 oz of gold equivalent ("Au Eq.").
• Production at Costerfield (Australia) was 6,203 oz Au and 766 t Sb, significantly greater volumes of both metals than in the first quarter of 2012. The production increase was due to substantially higher mine output resulting from refinements to the cemented rock fill long-hole stoping mining method and plant throughput improvement enabled by the installation of a mobile crusher in the third quarter of last year.
• Production at Cerro Bayo (Chile) was 4,432 oz Au and 611,441 oz Ag, significantly greater than in the first quarter of 2012 due to higher grades and tonnes mined and processed as the mine completed its ramp-up to 1,200 tonnes per day as planned.

^[1]Quarterly Au Eq. oz produced is calculated by multiplying the saleable quantities of Au, Ag, and Sb in the quarter by the respective average market prices of the commodities in the quarter, adding the three amounts to get a "total contained value based on market price", and then dividing that total contained value by the average market price of Au in the quarter.  Average Au price in the quarter is calculated as the average of the daily LME PM fixes in the quarter, with price on weekend days and holidays taken of the last business day; average Sb price in the quarter is calculated as the average of the daily average of the high and low Rotterdam warehouse prices for all days in the quarter, with price on weekend days and holidays taken from the last business day; average Ag price in the quarter is calculated as the average of the daily London Broker's silver spot price for all days in the quarter, with price on weekend days and holidays taken from the last business day.  The source for all prices is http://www.metalbulletin.com. 

The Company's sales quantities of all three metals closely matched production quantities, reflecting steady states of the Company's concentrate shipping processes.
