Mandalay Resources Corporation Announces Record Production and Sales Results for the Fourth Quarter and Full Year 2012 and Reiterates 2013 Production Guidance

TORONTO, January 14, 2013 /PRNewswire/ --

Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND) announced today record production and sales results for the fourth quarter and year-end, 2012. The Company is also re-affirming its production guidance for 2013.

Brad Mills, Chief Executive Officer of Mandalay, commented: "Our record fourth quarter and full year production and sales results builds on our strong history of delivering planned performance. We look forward to continuing this trend in 2013 as we expect to expand our Cerro Bayo operations to 1,400 tonnes per day mined by the first quarter of 2014 and initiate development of the Cuffley Lode at our Costerfield mine in the third quarter of 2013. I wish to thank all Mandalay personnel for helping us deliver on our promises in 2012 and building a highly profitable, dividend-paying, growing mining company."

Saleable Production for the three months ended December 31, 2012:

• The Company produced a total of 10,927 ounces ("oz") gold ("Au"), 785 tonnes ("t") antimony ("Sb") and 895,222 oz silver ("Ag"), representing a total of 33,537 oz of gold equivalent ("Au Eq.").
• Production at Costerfield (Australia) was 5,907 oz Au and 785 t Sb, significantly greater volumes of both metals than in the fourth quarter of 2011. The production increase was due to substantially higher mine output resulting from the Company refining its mining method (blast hole stoping with cemented rock fill). Processing throughput rose to an average of 10,639 tonnes per month in the fourth quarter of 2012 versus 5,448 tonnes per month in the fourth quarter of 2011.
• Production at Cerro Bayo (Chile) was 5,020 oz Au and 895,222 oz Ag, significantly greater than in the fourth quarter of 2011 due to higher grades and tonnes mined and processed as the mine achieved planned design performance.

Saleable Production for the year ended December 31, 2012:

• For the full year of 2012, the Company produced a total of 35,125 oz Au, 2,481 t Sb and 2,911,595 oz Ag, (107,941 oz Au Eq.), achieving or exceeding the Company's previous guidance.
• Production at Costerfield (Australia) reached 18,036 oz Au and 2,481 t Sb, resulting in significantly greater volumes of both metals compared to 2011 as both mine output and plant throughput exceeded design levels and the impact of lower dilution from the new stoping method improved plant head grade.
• Production at Cerro Bayo (Chile) was 17,089 oz Au and 2,911,595 oz Ag, significantly greater than in 2011 due to the completion of the ramp-up plan.

^[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 from 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. Year-end Au Eq. oz is the total of the quarterly oz derived as above.

^[2]Quarterly Au Eq. oz sold is calculated by multiplying the saleable quantities of Au, Ag, and Sb in the quarter by the respective quarter end market prices of the commodities, 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 for the quarter. Year-end Au Eq. oz is the total of the quarterly oz derived as above. Au Eq. values for 2011 have been re-calculated according to the above reporting policy. The source for all prices is http://www.metalbulletin.com with price on weekend days and holidays taken from the last business day.

The Company's sales quantities of all three metals closely matched production quantities in the fourth quarter, reflecting steady state of the Company's concentrate shipping process. The small difference between production and sales for the full year represents growth in finished product inventory as production has increased.

Reiteration of 2013 Production Guidance

The Company is pleased to reiterate its full year production for 2013. This guidance assumes a previously anticipated 15% decline in grade at Cerro Bayo in the first quarter of 2013 relative to the grades delivered in the fourth quarter of 2012.
