Mandalay Resources Corporation Announces Production and Sales Results for the Third Quarter 2018

TORONTO, Oct. 15, 2018 (GLOBE NEWSWIRE) -- Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX: MND, OTCQB: MNDJF) announced today its production and sales results for the third quarter of 2018.

Mandalay produced a consolidated 16,874 saleable ounces of gold equivalent and sold 18,450 ounces of gold equivalent in the third quarter of 2018.

Dominic Duffy, President and Chief Executive Officer of Mandalay, commented, "The third quarter of 2018 was lower than as expected, however the Company expects to see production improvements at both operations over the next quarter and into 2019. At Björkdal, we're anticipating a marked improvement in the rate of higher grade ore feed that is delivered to the mill. At Costerfield, with the dewatering of the Brunswick Lode and capital development work completed in the third quarter as planned, production of the higher grade Brunswick stopes is expected in the fourth quarter."

Mr. Duffy continued, "Björkdal produced 8,504 ounces of gold in the third quarter of 2018. Third quarter production was impacted by a bottleneck in the haulage rate from the underground mine to the mill, as delays were encountered in the delivery of new trucks with the changeover of the underground haulage contractor. This meant increased processing of lower grade stockpile ore during the quarter, instead of the higher grade ore. We expect this bottleneck to be resolved early in the fourth quarter as the new haulage trucks are delivered to site, allowing the haulage rate of the higher grade underground ore to increase."

Mr. Duffy concluded, "Costerfield produced 8,370 gold equivalent ounces in the third quarter of 2018. With the production transition of the Brunswick Lode completed, we expect an increase in ounces from the development and stoping of the higher grade areas of the mine. The infill and extension drilling at the high-grade Youle Lode continued in the third quarter with promising results. The Company will provide an update on these results once the drilling program is completed and results are confirmed (see announcements April 3, and June 27, 2018)."

• The Company produced a total of 13,442 ounces gold and 505 tonnes antimony, representing a total of 16,874 ounces of gold equivalent production in the third quarter of 2018, versus 20,603 ounces gold and 804 tonnes of antimony in the third quarter of 2017, representing a total of 25,819 ounces of gold equivalent.

Table 1 ? Third quarter and nine months saleable production for 2018 and 2017

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.
