Mandalay Resources Corporation (TSX: MND) (OTCQB: MNDJF) announced its production and sales results for the fourth quarter and full-year 2021 and provides production and cost guidance for 2022.

Fourth Quarter and Full-Year 2021 Production Highlights:

• Exceeded full-year 2021 production guidance with a consolidated saleable gold equivalent production of 123,002 ounces – highest total since 2017;
• Full-year consolidated saleable gold equivalent sold was 126,241 ounces – highest amount since 2017;
• Achieved year-over-year production growth of 19% and sales growth of 26% as compared to 2020;
• Fourth quarter consolidated 38,904 ounces of gold equivalent sold – highest quarterly amount since Q2 2016; and
• Costerfield’s highest ever quarterly saleable gold equivalent production of 19,507 ounces.

Production and Cost Guidance for Full-Year 2022:

• 2022 consolidated production guidance of 118,000 – 130,000 ounces of gold equivalent produced at an expected cash cost of $700 – $900 and all-in sustaining cost of $1,100 – $1,300.

Dominic Duffy, President and CEO of Mandalay, commented:

“Mandalay Resources finished the year strongly with Costerfield achieving a historic high in quarterly saleable gold equivalent production with 19,507 ounces. On a consolidated basis, the 32,362 saleable ounces of gold equivalent produced was the Company’s second highest quarterly result of 2021 and the full-year 123,002 ounces of saleable gold equivalent produced not only exceeded our 2021 guidance, but was also the Company’s best result since 2017. The consecutive year-over-year improvements since 2019 clearly demonstrate the stability at Björkdal and the growing quality of our anchor asset at Costerfield.

“Stemming from shipment backlogs, a higher-than-average level of concentrate was sold at Costerfield in December resulting in 26,877 ounces of gold equivalent sold during Q4. The receipt of cash from December’s shipments however will be recognized in 2022. Moreover, the full-year saleable gold equivalent production of 68,729 ounces at Costerfield represented an 18% year-over-year improvement. The Company anticipates an incremental improvement to Costerfield’s production profile during 2022 as stoping ramps up at Youle and with the initiation of production from the high-gold grade deposit Shepherd.

“At Björkdal, the 11,190 ounces and 45,236 ounces of saleable gold ounces produced during the fourth quarter and full-year respectively, was in line with previous quarters and year. The site continued with its step changes aimed at reducing dilution and we expect grades to lift and stabilize at planned levels during 2022. For 2022, Björkdal will increase its stoping rates within the lower, higher grade levels of the Aurora zone and will maintain the operational goal of achieving 1.2 million tonnes of underground ore per annum.

“At Cerro Bayo, processing continued up until December 1, 2021, when the Company successfully completed the sale of the asset to Equus Mining. During September and October, the site produced 1,665 ounces of saleable gold equivalent.

“For 2022, the Company anticipates a consolidated production between 118,000 – 130,000 ounces of gold equivalent at an expected cash cost of $700 – $900 and all-in sustaining cost of $1,100 – $1,300. The Company is also looking forward to following up on the highly successful 2021 exploration campaign with an anticipated exploration spend between $7 – $9 million at Costerfield and between $4 – $5 million at Björkdal during 2022.”

Table 1 – Fourth Quarter and Full-Year Saleable Production for 2021 and 2020

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 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 and Ag prices in the periods are 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.
