Lundin Gold Reports High-Grade Gold Results including 124.27 g/t Au over 11.00 Metres at FDNS and 242.64 g/t Au over 3.30 Metres at Bonza Sur; Conversion Drilling Commences at FDN East

VANCOUVER, BC, Oct. 26, 2026 /CNW/ — Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) (OTCQX: LUGDF) (“Lundin Gold” or the “Company”) is pleased to report strong results from its ongoing conversion and near–mine exploration drilling programs at the Fruta del Norte (“FDN”) gold mine in southeast Ecuador. PDF Version

Drilling programs continue to deliver positive results across multiple distinct epithermal gold deposits at FDN. The commencement of conversion drilling at FDN East is an important step in refining the geological model of the deposit, while underground development advances to provide improved access for exploration drilling.

Highlights

• FDNS exploration: Drilling continues to extend mineralization beyond the Mineral Resource envelope, including new zones in the easternmost veins, along the southern extension, and at depth.
• FDNS conversion: Drilling confirms continuity and higher-grade zones in the northern and southern areas of the deposit, supporting further Mineral Reserve additions. Highlights include 124.27 grams per tonne (“g/t”) gold (“Au”) over 11.00m.
• Bonza Sur exploration: Drilling confirms continuity of higher-grade zones within the broader mineralized system, including the highest-grade interval ever recorded at the deposit, 242.64 g/t Au over 3.30m.
• FDN East conversion: Initial conversion drilling confirms the continuity of mineralization and is refining the geological model. Underground development is advancing to provide improved access for continued exploration drilling and to support potential future production.

Jamie Beck, President and CEO, commented, “Our near-mine exploration programs continue to deliver exceptional results at FDNS, FDN East, and Bonza Sur. As these gold deposits continue to expand alongside the FDN deposit, we are increasingly confident in their combined potential to sustain production at current levels over the long-term. The higher-grade zones emerging at Bonza Sur, including the highest-grade interval ever recorded at the deposit, further strengthen that potential.

The start of conversion drilling at FDN East is an important step in refining our understanding of the deposit as underground development advances to improve drilling access. The rapid evolution of the Fruta del Norte district into a cluster of epithermal gold deposits demonstrates the extraordinary geological potential of the property and the ability of our teams not only to discover new deposits, but to rapidly advance them towards future production.”

FDNS

Underground drilling continues to advance at FDNS, located directly south of the FDN deposit. In 2026, the Company declared an inaugural Mineral Reserve of 0.54 Moz (2.50 Mt at 6.66 g/t Au) approximately 18 months after the deposit’s discovery.

The current conversion drilling program aims to upgrade Inferred Resources to the Indicated category and to support further Mineral Reserve additions. Since January 2026, approximately 22,979 metres of drilling has been completed across 190 holes and meaningful intercepts continue to be recorded (Figure 2). Outstanding drill results in both the northern portion and the southern extension of FDNS confirm the continuity of mineralization and highlight higher-grade zones for further delineation.

Exploration drilling is extending the limits of the FDNS deposit and providing areas for further potential mineral resource growth (Figure 3). Drilling along the upper continuity of the easternmost veins has intercepted new mineralization and provides additional areas for further drilling. Along the southern extension of FDNS, toward the northern end of Bonza Sur, drilling intercepted distinct higher-grade zones, while also intercepting the continuity of the vein system at depth. Results received to date are summarized in Table 1. Five underground rigs are currently operating at FDNS.

FDN EAST

At FDN East (a buried epithermal deposit located less than 100 metres from the main FDN mine infrastructure) the Company recently initiated a conversion drilling program aiming to upgrade Inferred Resources to the Indicated category and improve the confidence of the geological model (Figure 4). This conversion program is ongoing as underground development advances toward the FDN East deposit. This development will provide improved access for the exploration drilling program and support potential future production. As of September 30, 2026, 39 metres of underground development has been completed towards the deposit.

Since August 2026, approximately 4,237 metres of conversion drilling has been completed across 15 holes along the western portion of the deposit (Figure 4). Most of the drill holes have intercepted the continuity of the mineralization, confirming the current geological interpretation. Drilling has also intercepted high-grade mineralized veins near FDN, providing new areas for further drilling. Currently, one underground rig is operating at FDN East. Results received to date are presented in Table 2.

Bonza Sur

Exploration drilling is advancing at Bonza Sur, assessing the continuity and geometry of the high-grade zones within the mineralized envelope. The program is currently focused on the northern portion of the deposit where drilling continues to confirm the continuity of mineralization. Of note, drill hole BLP-2026-559 returned the highest-grade interval ever recorded at the deposit, demonstrating further exploration potential in this area (Figure 5). Currently, three surface rigs are drilling at Bonza Sur. Results received to date are summarized in Tables 1 and 3.
