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

TORONTO, July 10, 2018 (GLOBE NEWSWIRE) -- Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX:MND) (OTCQB:MNDJF) announced today its production and sales results for the second quarter of 2018.

Mandalay produced a consolidated 22,348 saleable ounces of gold equivalent and sold 22,052 ounces of gold equivalent in the second quarter of 2018.

Dominic Duffy, President and Chief Executive Officer of Mandalay, commented, "The second quarter of 2018 was a transitional production and sales quarter for Mandalay as the Company began to transition production into the Brunswick Lode at Costerfield. Over the next two quarters we expect to see production lift at both operations due to the initiation of mining operations at Brunswick, and mining anticipated higher grades at Björkdal.  Consequently, the Company remains confident that it will reach its 2018 production guidance of 101,000 to 113,000 gold equivalent ounces."

Mr. Duffy continued, "Björkdal produced 14,017 ounces of gold in the second quarter of 2018. The Company is in the process of adding automation controls to the processing plant and we are beginning to see additional recovery improvements of approximately 1% as the circuit stabilizes. This is also expected to result in the removal of more gold in the gravity circuit, with the overall impact of improving our payables."

Mr. Duffy concluded, "Costerfield produced 8,331 gold equivalent ounces in the second quarter of 2018. Second quarter production was lower than in the previous year quarter due to a combination of expected lower mining grades and available ore in the current producing areas. The Company intercepted the Brunswick Lode during the second quarter and is currently dewatering this Lode. We expect a significant increase in production once dewatering is completed and mining initiated during the third quarter. Simultaneously, we are aggressively continuing our infill and extensional drilling program on the Youle lode."

• The Company produced a total of 19,154 ounces gold and 503 tonnes antimony, representing a total of 22,348 ounces of gold equivalent production in the second quarter of 2018, versus 28,219 ounces gold, 765 tonnes of antimony and 359,457 ounces silver in the second quarter of 2017, representing a total of 38,491 ounces of gold equivalent.

Table 1 ? Second quarter and six month 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.
