Mandalay Resources Corporation Announces Production and Sales Results for the First Quarter of 2017

TORONTO, April 12, 2017 (GLOBE NEWSWIRE) -- Mandalay Resources Corp. ("Mandalay" or the "Company") (TSX:MND) announced today its production and sales results for the first quarter of 2017. In the first quarter of 2017, Mandalay produced 32,481 saleable ounces of gold equivalent and sold 34,801 ounces of gold equivalent.

Mark Sander, President and Chief Executive Officer of Mandalay, commented, "Mandalay's production and sales in the first quarter of 2017 show that the Company is on track to delivering on our guidance range of 138,000 to 163,000 ounces of gold equivalent for 2017. First quarter sales were within the guidance range given in the press release on February 16, 2017, and we expect improving production at all sites in the balance of the year to support higher sales in the coming quarters.

"Costerfield continued its dependable performance with production of 12,891 gold equivalent ounces. Production is consistent with the previous two quarters and the current grade profile of the mine. We expect to see output lift at Costerfield in subsequent quarters because mining grades are forecast to increase as we extract higher-grade stopes in the Cuffley and N lodes later in the year.

"Björkdal produced 10,648 ounces of gold in the first quarter of 2017, down from 12,185 ounces in the same period of 2016, but very similar to the fourth quarter of 2016 production of 10,934 ounces. Björkdal delivered strong, near-record sales of 13,121 ounces in the first quarter of 2017 as the record monthly production of December, 2016, was sold. During the first quarter, production of higher-grade underground ore was limited due to a bottleneck with respect to underground haulage. Additional underground loading and haulage capacity was added at the end of March, which is expected to directly increase the stope production and in turn increase the rate of delivery of high-grade underground ore for the remainder of the year. As well, in the second quarter we are increasing the length of our jumbo booms to permit longer cuts per blast and therefore increase underground development rates, which is also expected to contribute to increasing the delivery rates of underground ore. The Björkdal flotation expansion project is progressing approximately on schedule. Upon commissioning in the third quarter of 2017, we expect a 1.7% increase in gold recoveries. All these improvements point toward lifting production rates through the year."

Dr. Sander concluded, "Operationally, Cerro Bayo has implemented a number of initiatives to generate cost reductions and improve operational efficiency. Mine production during the first quarter of 435,076 ounces of silver and 2,735 ounces of gold demonstrates significant quarter-over-quarter progress compared to production of 365,214 ounces of silver and 2,807 ounces of gold in the previous quarter. We expect to see production continue to grow over the remainder of 2017 as a greater number of development headings and production stopes become available from the Coyita mine. As well, we have optimized plant shift schedules to reduce costs and match the planned ore production of the mine."

Table 1 - Mandalay Quarterly Saleable Production

¹ Quarterly gold equivalent ounces ("Au Eq. oz") produced is calculated by multiplying the saleable quantities of gold ("Au"), silver ("Ag"), and antimony ("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.
