Mandalay Resources Corporation Announces Production and Sales Results for the Second Quarter, 2015

TORONTO, ON, July 13, 2015 - Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND) announced today its production and sales results for the second quarter, 2015.
Brad Mills, Chief Executive Officer of Mandalay, commented, "Mandalay's second quarter production and sales results remained steady, and within our planned annual guidance range. Costerfield continued to produce at or near record levels and Björkdal performed as planned as we move forward with the optimization strategy. Cerro Bayo production declined from the same quarter last year due to several factors including lower grades being processed in the period; several days of lost time due to electrical infrastructure damage as a result of strong wind conditions; and the strike action at the end of the quarter, which was resolved on July 1, 2015.
Our focus in the second half of the year is to continue to maintain the solid performance at Costerfield and begin the ramp-up of grade at Björkdal as the new assay lab opens, and starts to impact mining decisions. Our new optimization plan continues to be implemented, with our stated goal of margin expansion by producing more gold at a reduced cost per ounce. At Cerro Bayo we expect improved grades in the second half as new stoping areas open up at Delia SE."
Overall, the Company maintains its full year production guidance range of 167,000 to 185,000 gold equivalent ounces.

Saleable production for the three months ended June 30, 2015:

The Company produced a total of 26,418 ounces ("oz") gold ("Au"), 842 tonnes ("t") antimony ("Sb") and 597,489 oz silver ("Ag"), representing a total of 40,717 oz of gold equivalent ("Au Eq.") production.

Production at Costerfield (Australia) was 9,563 oz Au and 842 t Sb, a greater volume of Au and a slightly lower volume of Sb than in the second quarter of 2014. The overall increase in production was due to higher tonnages and grades mined and processed.

Production at Cerro Bayo (Chile) was 5,361 oz Au and 597,489 oz Ag, lower than the year- ago quarter due to a combination of lower grades and lower production volumes than the prior period.

Production at Björkdal (Sweden) was 11,494 oz Au. The Björkdal mine was acquired on

September 9, 2014.

Saleable production for the six months ended June 30, 2015:

The Company produced a total of 54,158 oz Au, 1,811 t Sb and 1,188,243 oz Ag, representing a total of 82,993 oz of Au Eq. production.

Production at Costerfield was 19,979 oz Au and 1,811 t Sb, greater volume of Au and Sb than in the corresponding six months of 2014.

Production at Cerro Bayo was 10,366 oz Au and 1,188,243 oz Ag.

Production at Björkdal was 23,813 oz Au.

1 Quarterly Au Eq. oz produced is calculated by multiplying the saleable quantities of Au, Ag, and Sb in the period by the respective average market prices of the commodities in the period, 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 period. Average Au price in the period is calculated as the average of the daily LME PM fixes in the period, with price on weekend days and holidays taken of the last business day; average Sb price in the period is calculated as the average of the daily average of the high and low Rotterdam warehouse prices for all days in the period, with price on weekend days and holidays taken from the last business day; average Ag price in the period is calculated as the average of the daily London Broker's silver spot price for all days in the period, with price on weekend days and holidays taken from the last business day.
