As I step into the role of President and ChiefExecutive Officer, I am pleased to build on the strong foundation established by Ron Hochstein and the entire Lundin Gold team,and to lead the Company forward with a continued focus on disciplined operations, environmental and social responsibility, andlongterm value creation. At our Fruta del Norte (“FDN”) mine, disciplined execution and continuous improvement once again delivered results thatreinforce the Tier 1 quality of this worldclass asset. Following the successful completion of the process plant expansion early inthe year, average throughput reached 5,009 tonnes per day, supporting annual gold production of 498,315 ounces in line withour elevated guidance range. Strong operating performance, combined with a historically high gold price environment, delivered record financial resultsacross all key metrics. During the year, we sold 503,330 ounces of gold at an average realized gold price¹ of $3,594 per ounce,generating record revenues of $1.78 billion. Despite higher royalties and statutory employee profitsharing associated withstronger gold prices, disciplined cost control resulted in Cash Operating Costs¹ of $838 per ounce sold and All-In Sustaining Cost¹(“AISC”) of $1,015 per ounce sold, maintaining FDN’s position as a low cost, high margin operation. These results translated into record Free Cash Flow¹ of $926 million in 2025, demonstrating the exceptional cash-generatingcapability of our business. Over the course of the year, our strong balance sheet and financial flexibility enabled us to return$664 million to shareholders through an enhanced dividend framework, including the introduction of a variable dividend linkedto normalized free cash flow that supplements our fixed dividend, reinforcing our commitment to meaningful capital returns. Exploration remains central to Lundin Gold’s long-term strategy. In 2025, we executed our largest exploration program todate, completing 121,519 metres of drilling across resource conversion and near mine targets. A central focus was FDN South(“FDNS”), where continued drilling success supported the declaration of an initial Mineral Reserve. Based on the strength ofthese results, we made the development decision for FDNS in early 2026, advancing it as a key component of Fruta del Norte’slong-term mine plan. Our Mineral Reserve and Mineral Resource up
