Mandalay Resources Corporation Announces Production and Sales Results for the Fourth Quarter and Full-Year 2020, Provides Production and Cost Guidance for 2021

TORONTO, Jan. 14, 2021 - 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 2020 and provided production and cost guidance for 2021.

Fourth Quarter and Full-Year 2020 Production Highlights:

• Met full-year 2020 production guidance with a consolidated 103,444 ounces of gold equivalent produced;
• Achieved 35% year-over-year production growth in 2020;
• Produced 24,488 saleable gold ounces during Q4 2020, the Company’s highest quarterly saleable gold production since Q4 2017;
• Recorded fifth consecutive quarterly improvement in consolidated saleable gold production; and
• Provided 2021 full-year consolidated production and cost guidance of 105,000 – 117,000 ounces of gold equivalent produced at expected cash cost of $800 – $1,000 and all-in sustaining cost of $1,100 – $1,350.
  

In the fourth quarter of 2020, Mandalay produced a consolidated 27,351 saleable ounces of gold equivalent and sold 24,742 ounces of gold equivalent. For the full-year 2020, Mandalay produced 103,444 ounces of gold equivalent and sold 99,935 ounces of gold equivalent.

Dominic Duffy, President and Chief Executive Officer of Mandalay, commented, “Mandalay’s significant production performance in the fourth quarter of 2020 reflects the continued strengthening and improvement of our operations. The fourth quarter of 2020 was the Company’s best quarterly consolidated gold production quarter since the fourth quarter of 2017 and marks the fifth consecutive quarterly improvement in saleable gold production.”

Mr. Duffy continued, “In 2020, Costerfield was a high performing anchor asset for the Company that drove the Company’s operational and financial turnaround, producing and selling record amounts of both gold and antimony for the year. The high-grade Youle vein continued to deliver excellent results in the fourth quarter of 2020, as head grades averaged 11.22 g/t gold and 3.5% antimony processed. Overall, Costerfield produced 15,099 saleable gold equivalent ounces during the fourth quarter of 2020 and 58,148 ounces of gold equivalent for full-year 2020. As compared on an annual basis, Costerfield’s 2020 production rate increased by well over 2x – a clear demonstration of the high-grade, high-quality ore of the Youle vein. During December we also began underground ore haulage through the newly established Brunswick portal. This halves the ore haulage distances from Youle as we seek to continue lowering our operational costs. The site is pushing ahead with the cavitation tube flotation project, aimed at improving gold recoveries, however, due to manufacturing and delivery delays related to COVID-19 the project has been delayed further. We are forecasting commissioning of the project in the first quarter of 2021. Over the course of 2021, we expect to see a continuation of high-gold grades as we mine deeper into Youle, setting Costerfield up for another strong year with a forecast of approximately 53,000 – 60,000 ounces of saleable gold equivalent produced at a cash cost and all-in sustaining cost per equivalent ounce between $675 – $825 and $950 – $1,100, respectively.”

Mr. Duffy added, “At Björkdal, we saw significant improvements resulting in production of 12,252 saleable gold ounces in the fourth quarter – the highest quarterly amount in 2020 – and 45,296 ounces of saleable gold for the full-year 2020. 2020 was a transitional year for Björkdal operationally, one in which is setting the foundation for an expected improved production profile in 2021 as we continue to institute; the steady ramp-up in supplying the mill with higher-margin underground ore, more scheduled stoping and advancing development into Aurora’s higher-grade lower levels. For 2021, we are forecasting a significant production increase at Björkdal, with expected production of 52,000 – 57,000 gold ounces at a cash cost and all-in sustaining cost per ounce of between $900 – $1,050 and $1,200 – $1,350, respectively.”

Mr. Duffy continued, “Mandalay finished the year with a consolidated 103,444 ounces of gold equivalent produced, a considerable 35% improvement year-over-year. At the same time, safety was, and will continue to be a primary focus of the Company. The Company had its best safety record to date for full-year 2020, with a Lost Time Injury Frequency Rate of 2.86. We look forward to building upon these achievements and creating an even stronger enterprise in 2021. In addition to production and safety, another primary focus will be exploration as we ramp up the spending and drilled meters at both sites over the course of 2021. We expect this to unlock further value and extend mine life of our assets.”

Mr. Duffy concluded, “Looking ahead, Mandalay is planning to begin a trial processing of waste dumps carrying gold and silver mineralization over the course of the first quarter of 2021 at Cerro Bayo. However, due to the trial nature of this project, no production has been attributed towards our 2021 guidance. As such, the Company expects to produce an improved consolidated 105,000 – 117,000 ounces of gold equivalent at $800 – $1,000 and $1,100 – $1,350 per ounce cash costs and all-in sustaining cost, respectively in 2021. This guidance flows from the continuing commitment and dedication of our employees, contractors and the quality of both of our assets. Further details on the 2021 guidance can be found at the end of this press release.”

Table 1 – Fourth Quarter And Full-Year Saleable Production for 2020 and 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.
