Mandalay Resources Corporation Announces Production and Sales Results for the First Quarter of 2020

TORONTO, April 13, 2020 (GLOBE NEWSWIRE) -- Mandalay Resources Corporation ("Mandalay" or the "Company") MNDMNDJF announced today its production and sales results for the first quarter of 2020.

In the first quarter of 2020, Mandalay produced a consolidated 25,677 saleable ounces of gold equivalent and sold 24,276 ounces of gold equivalent.

Dominic Duffy, President and Chief Executive Officer of Mandalay, commented, "The first quarter of 2020 showed a significant increase in both gold and antimony production as production from the high-grade Youle vein at Costerfield began to ramp up. Gold and antimony production increased 36% and 62%, respectively, compared to the fourth quarter of 2019."

Mr. Duffy continued, "The significant increase in production was driven by the excellent results from Costerfield. The site produced 14,927 saleable gold equivalent ounces, which marks the highest level of production achieved since the second quarter of 2016. Included within this production was a record 1,108 tonnes of saleable antimony, which is the highest quarterly antimony production the site has ever produced. We are excited with the realized outcomes from the Youle vein as the mill processed an average head grade of 12.6 g/t and 5.4% of gold and antimony, respectively, over the quarter. These are considerable improvements versus the 2019 full year averages of 5.1 g/t gold and 2.5% antimony. We expect these production rates at Costerfield to be sustained as the Youle vein becomes the more prominent source of ore feed over the remainder of the 2020."

Mr. Duffy continued, "At Björkdal, first quarter production was in line with the previous quarter, although lower than forecast. This was due to a change out of our major underground haulage contractor, which negatively impacted underground production rates in January and February. With this transition completed we expect to be able to maintain budgeted production rates going forward for 2020. During the quarter we initiated the first production stope in the Aurora zone and saw positive results when the material was processed. We expect the Aurora zone to increase production for the remainder of 2020."

Mr. Duffy concluded, "These excellent first quarter production and sales results represent a strong start to 2020 for Mandalay. While we currently expect this strong operating performance to continue, the COVID-19 pandemic creates potentially significant uncertainties and difficulties for everyone, and Mandalay is no exception. For now, we are maintaining our existing 2020 production guidance, but we continue to closely monitor the situation in both Australia and Sweden and will make adjustments, if necessary. We are continuing to manage the risks resulting from COVID-19 with the controls as outlined in our March 20, 2020 press release. Business continuity plans are in place with site-specific contingency considerations, should they be needed."

Table 1 – First Quarter Saleable Production for 2020 and 2019, and Fourth Quarter of 2019

1.    Quarterly gold equivalent ounces ("Au Eq. oz") produced is calculated by multiplying the saleable quantities of gold ("Au"), and antimony ("Sb") in the period by the respective average market prices of the commodities in the period, adding the two 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.
