LUNDIN GOLD ACHIEVES A NEW HIGH OF CONTAINED GOLD OUNCES IN MINERAL

RESERVES AND MINERAL RESOURCES AT FRUTA DEL NORTE

Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) (OTCQX: LUGDF) ("Lundin Gold" or the "Company")

today reports its updated estimates of Mineral Reserves and Mineral Resources as at December 31, 2024 for

its Fruta del Norte gold mine (“FDN”) in Ecuador. The tables of the updated estimates of Mineral Reserves and

Resources can be found at the end of this release.

Highlights

• Based on contained gold ounces, the 2024 estimates are the highest ever published at FDN for Mineral

Reserves and Resources.

• Inferred Resources increased by 59% to 2.36 million ounces (“ Moz”) of contained gold from 13.95

metric tonnes (“Mt”) with an average grade of 5.27 grams per tonne (“g/t”) net of conversion of 0.65

Moz to Measured and Indicated.

o FDN South (“FDNS”) was the lead contributor to the Inferred Resource growth increasing

contained ounces from 0.73 Moz in 2023 to 2.09 Moz from 12.35 Mt with an average grade of

5.25 g/t.

• Measured and Indicated Mineral Resources increase d to 7.06 Moz of contained gold from 30.62 Mt

with an average grade of 7.17 g/t.

• Proven and Probable Mineral Reserves increased to 5.54 Moz of contained gold from 22.06 Mt with an

average grade of 7.81 g/t, after 2024 mining depletion of 0.54 Moz.

Ron Hochstein, President and CEO, commented, "I am extremely pleased to announce our year -end 2024

Mineral Reserve and Resource estimate, marking another year of significant growth for FDN. This latest update

represents the largest Reserve and Resource statement in the Company’s history based on contained gold

ounces. In addition to increasing our Mineral Reserves after mining depletion, our 2024 near-mine exploration

success at FDN and mainly FDNS has resulted in notable additions to our Inferred Resources, growing them by

1.7 Moz through the drill bit. With continued conversion and exploration programs planned for 2025, I am very

excited about the potential for further growth, including our plans to publish an initial resource for Bonza Sur

later this year."

Inferred Mineral Resources Update

The 202 4 near mine exploration drilling program was successful at finding new ounces with the main

contribution coming from FDNS. Inferred Resources increased by 59% to 2.36 Moz of contained gold from

13.95 Mt with an average grade of 5.27 g/t net of conversion of 0.65 Moz to Measured and Indicated. FDNS

contributed 2.09 Moz to the Inferred Resource from 12.35 Mt with an average grade of 5.25 g/t with most of

this Mineral Resource showing grades above 7 g/t as illustrated in Table 1 below. A more conservative resource

2

model was developed by applying cut-off grades and mining parameters to Inferred Resources, which resulted

in engineering reductions but increased the accuracy of future conversion potential. The FDNS Inferred

Resource will be a focus of the 2025 conversion drilling program.

Measured and Indicated Mineral Resources Update

The 2024 conversion drilling campaign was successful at reclassifying Inferred Resources to Indicated in areas

immediately beyond the current Reserve boundary. The new areas of Indicated Resources are illustrated in

Figure 3, and include extensions to the north, at depth, and to the south of the FDN deposit.

Annual Information Form dated March 26, 2024 under the Company’s profile on SEDAR+ at www.sedarplus.ca.

Mineral Reserves Update

Proven and Probable Mineral Reserves increased to 5.54 Moz of contained gold from 22.06 Mt with an average

grade of 7.81 g/t after 2024 mining depletion of 0.54 Moz. The addition of 2.03 Mt was achieved at a grade of

8.01 g/t which is higher than the average 2023 Mineral Reserve grade of 7.89 g/t and was offset by 2024 mining

depletion of 1.67 Mt at 10.01 g/t.

Increases to the Reserve estimate are primarily due to successful conversion drilling, modifications to the mine

design, and some changes to technical parameters. Mine design modifications include replacement of drift

and fill with longhole stoping and improvements in mining dilution and recovery estimates. Technical

parameter modifications include minor changes in cut -off grade estimates. The assumed gold price was

increased to $1,500/oz from $1,400/oz from the year prior.
