LUNDIN GOLD REPORTS SIGNIFICANT EXPANSION AT BONZA SUR

New drilling results highlight the potential of the gold deposit

VANCOUVER, BC, Dec. 3, 2024 /CNW/ – Lundin Gold Inc. LUG (Nasdaq Stockholm: LUG) LUGDF (“Lundin Gold” or the “Company”) is pleased to announce additional drilling results from its ongoing 2024 near-mine exploration program at Bonza Sur, in close proximity to its 100%-owned Fruta del Norte (“FDN”) gold mine in southeastern Ecuador.  Recent results confirm the significant size of the Bonza Sur mineral deposit. Drilling has extended the deposit’s length by 800 metres to approximately 2.6 kilometres and widened it to 150 metres.  Importantly, Bonza Sur remains open for further discovery in all directions and at depth.

Highlights from the ongoing drill program at Bonza Sur are outlined below (not true widths).  Detailed results are provided at the end of this release (see Appendix 1).

Bonza Sur Exploration Drilling Highlights (not true widths):

• Drill hole AMN -2024-156 intersected 2.35 grams per tonne (“g/t”) of gold (“Au”) over 100.30 m from 333.2 m, including:
  • 3.30 g/t Au over 53.20 m from 353.8m
• Drill hole BLP-2024-189 intersected 1.54 g/t Au over 123.50 m from 72.90 m, including:
  • 3.08 g/t Au over 48.0 m from 81.3m, with:
  • 10.06 g/t Au over 7.60 m
• Drill hole BLP-2024-162 intersected 1.43 g/t Au over 115.60 m from 47.40 m including:
  • 2.43 g/t Au over 58.10 m from 92.90m, with:
  • 4.58 /t Au over 20.50m
• Drill hole BLP-2024-173 intersected 1.22 g/t Au over 133.20 m from 31.90 m including:
  • 2.54 g/t Au over 49.80 m from 113.40m, with:
  • 17.29 g/t Au over 2.9m

Ron Hochstein, President and CEO, commented, “The significant and rapid advance of Bonza Sur from an early-stage exploration target to a mineral deposit is an exciting time for Lundin Gold.  Our drilling program continues to highlight the meaningful potential of this new discovery.  Recent results have defined a much larger mineralized system close to surface that extends over 2.6 kilometres and remains open for further expansion.  The Company plans to release an initial mineral resource at Bonza Sur mid-year 2025 and drilling is ongoing.”

NEAR-MINE PROGRAM

The ongoing near-mine exploration program continues to unlock the significant potential of Lundin Gold’s world-class land package.  2024 marks the largest drilling program ever undertaken on the concessions that host the FDN mine.  To date, approximately 56,110 metres of drilling have been completed, with a target of at least 65,000 metres in 2024, primarily focused on the Bonza Sur deposit.

Over recent months, the program has focused on efforts to define and expand Bonza Sur and a total of 43 drill holes across 17,315 metres have been completed.  Assay results for these holes are provided in Tables 1 and 2 of this release.  Drilling is ongoing, and results for some holes are still pending.

Bonza Sur

Initially discovered through drilling a geochemical soil anomaly one kilometre south of the FDN mine, Bonza Sur continues to evolve as a substantial mineral deposit.  The resource envelope now extends over 2.6 kilometres along strike, is 150 metres wide, and reaches at least 500 metres deep (see Figures 1, 2, and 3).  Since its 2023 discovery, over 90 drill holes have been completed, and results consistently point to further growth potential.

Bonza Sur is interpreted as a shallow, disseminated gold-silver epithermal system situated east of the East Fault, a critical structural control at FDN. Gold mineralization is characterized by a broad hydrothermal halo with a higher-grade core associated with quartz-chalcedony-manganoan-carbonate veins and veinlets, enveloped by a lower-grade gold zone with silica-illite and sulfides.

The recent drilling program, detailed in Tables 1 and 2, has expanded Bonza Sur in all directions.  In the south, drilling has extended mineralization by 800 metres to 2.6 kilometres, with potential for further growth.  Drill hole AMN-2024-156 (2.35 g/t Au over 100.30m from 333.2m) is a prime example of these strong results.  In the central area, drilling has expanded Bonza Sur laterally by 150 metres to the east.  In the north, drill holes have intersected a high-grade gold zone near the surface, surrounded by a wider disseminated gold halo, confirming the mineral envelope in this sector.

All drilling data is being integrated into a new geological model for Bonza Sur, and a metallurgical study is underway.  An initial mineral resource estimate is expected by mid-2025.  Currently, four drill rigs are active at Bonza Sur, focused on expanding the deposit both along strike and at depth.
