Mandalay Resources Corporation (TSX: MND) (OTCQB: MNDJF) announces strong operating results for the fourth quarter and full-year 2024. All currency references in this press release are in U.S. dollars, except as otherwise indicated.

Fourth Quarter 2024 Highlights:

• Consolidated production of 25,496 gold equivalent ounces:
  • Costerfield achieved its strongest quarter of 2024, producing 15,768 gold equivalent ounces;
  • Björkdal delivered stable production of 9,728 gold ounces.

Full-Year 2024 Highlights:

• Delivered 97,128 gold equivalent ounces, approaching the top end of the 2024 production guidance range of 90,000 to 100,000 gold equivalent ounces;
  • Gold: 85,669 ounces produced;
  • Antimony: 1,282 tonnes produced;
• Year-end cash balance of $76 million.

Frazer Bourchier, President and CEO, commented:

“We are pleased to have achieved the upper end of our production guidance range for 2024, reflecting the dedication, focus on operational execution and hard work of our teams across both operations. The exceptional performance at Costerfield, particularly in the fourth quarter, continues to underscore the cash generating potential of our assets and our ability to deliver consistent results. With a robust year-end cash position of $76 million, Mandalay remains well-positioned to capitalize on growth opportunities and maximize shareholder value.”

Ryan Austerberry, COO, commented:

“Both operations ended 2024 with strong performance, setting the stage for a solid start to 2025. At Costerfield, operational success was driven by excellent mining performance, reliable plant throughput and good recoveries. Mined ore tonnage exceeded targets, thanks to increased stoping activity from shorter tramming distances, and occasional use of larger equipment in closeouts. This enabled the site to achieve its strongest quarterly gold production of the year, totaling 12,125 ounces. During the quarter, average processed grades were 10.8 g/t for gold and 1.4% for antimony. For 2025, due to mine sequencing, we expect Costerfield’s production to range between 43,000 – 48,000 gold equivalent ounces, with higher production currently scheduled to return in 2026.

“At Björkdal, fourth quarter production remained consistent with previous quarters, delivering 9,728 gold ounces. In 2025, the focus will be on capital development to increase access to more veins and establishing production fronts to enhance operational flexibility. In 2025 production is expected to be 41,500 – 46,000 gold ounces, consistent with 2024 levels supported by stable processed grades and tonnage. The plan continues to prioritize higher-margin underground material while leveraging the existing low-grade surface stockpiles to fully utilize the plant’s 1.4 million tonne per annum capacity.”

Mr. Bouchier concluded: “I would like to extend my gratitude to our Board of Directors for their guidance and to our shareholders for their continued support. Most importantly, I want to thank our employees and contractors for their focus, commitment, and dedication in driving the Company forward.”

1. Quarterly gold equivalent ounces (“Gold Eq. (oz)”) produced is calculated by multiplying the production quantities of gold (“Au”), 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.
