Mandalay Resources Corporation Announces Production and Sales Results for the Fourth Quarter and Full Year 2018, Provides Production Guidance for 2019-2021

TORONTO, Jan. 16, 2019 - Mandalay Resources Corp. ("Mandalay" or the "Company") (TSX: MND, OTCQB: MNDJF) announced today its production and sales results for the fourth quarter and full-year 2018. The Company also announced its production guidance for 2019-2021.

In the fourth quarter of 2018, Mandalay produced a consolidated 19,173 saleable ounces of gold equivalent and sold 18,433 ounces of gold equivalent. For the full year ended December 31, 2018, Mandalay produced 81,568 saleable ounces of gold equivalent and sold 88,083 ounces of gold equivalent.

Dominic Duffy, President and Chief Executive Officer of Mandalay, commented, “Mandalay’s production in the fourth quarter of 2018 met the revised full-year 2018 production guidance for gold, antimony and gold equivalent ounces that we released to the market in November 2018. Fourth quarter production improved against the third quarter mainly due to the ramp up of underground trucking at the Björkdal mine as the new contract haulage fleet arrived over the course of the quarter. We expect production to continue to improve in the first quarter of 2019 as underground trucking at Björkdal is now at the planned rate.

“At Costerfield, the Company advanced development on the Brunswick lode which now has four development levels and is expected to begin stoping during the first quarter of 2019. The Company also continued capital development to the high-grade Youle lode, which is scheduled to be in production in the second half of 2019. During the fourth quarter of 2018, the Company produced 8,691 ounces of gold equivalent from Costerfield and 35,849 ounces of gold equivalent for the full-year 2018. We are expecting production improvements at the Costerfield mine to begin in the second half of 2019 when development begins on the high-grade Youle lode.

“At Björkdal, in the fourth quarter of 2018 we overcame the haulage capacity issue relating to the underground contractor, and the whole expected fleet of underground trucks arrived on site by December, resolving this issue. Production of higher-grade underground ore continued to increase though the quarter. Also, development continued on two levels on the recently released Aurora zone (see November 14, 2018 press release) with the first production stopes on this new discovery expected in the second half of 2019. Exploration drilling into the Aurora zone also continued. Björkdal produced 10,482 ounces of gold in the fourth quarter of 2018 and 45,719 ounces of gold for the full-year 2018.”

Mr. Duffy continued, “2018 was a challenging year for Mandalay’s operations as the Company’s production was adversely impacted by underground trucking issues at Björkdal and the delayed startup to Brunswick development at Costerfield. I am proud of our operational teams’ dedication and ability to address and resolve these challenges. With these issues behind us, we head into 2019 and beyond with optimism.”

Mr. Duffy concluded, “Most importantly, we are also pleased to provide our production guidance for the next three years, which shows the way forward for Mandalay and highlights significant organic production growth from our operations. We expect to increase Mandalay’s production in each year from 2019-2021, growing from the 81,568 ounces of gold equivalent produced in 2018 to 131,000-162,000 ounces of gold equivalent for 2021. We expect to see major production improvement from the Costerfield mine over this three-year period as the Youle lode is brought on-line, and production is expected to grow from the 35,849 ounces of gold equivalent produced in 2018 to 76,000-100,000 ounces of gold equivalent in 2021. We are also expecting a steady ramp up at Björkdal as underground production increases from the Aurora zone and higher-grade skarn bodies. This guidance, underpinned especially by the high-grade Youle deposit at Costerfield, reflects an exciting future for Mandalay.”

Table 1 – Fourth quarter and full year 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.

*Assumes metal prices of: Au $1,200/oz, Sb $8,200/t.

Mandalay’s 2019-2021 production guidance is based on:

• Björkdal – A steady ramp-up of production as the impacts of the higher-grade and significantly wider Aurora zone allows for increased underground production.
  
• Costerfield – High-grade Youle lode coming on-line in the second half of 2019 and continuing to ramp up production through 2021.
  
• Cerro Bayo – Due to the uncertainty related to the re-permitting of Cerro Bayo, no production is being incorporated into the guidance shown above.
