LUNDIN GOLD REPORTS EXCEPTIONAL DRILLING RESULTS AT FDNS AND FDN EAST WITH
FDNS ADVANCING TOWARDS INTEGRATION INTO MINE PLAN
Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) (OTCQX: LUGDF) ("Lundin Gold" or the "Company") is pleased to
announce positive results from its conversion and near-mine exploration drilling programs at its 100% owned Fruta del
Norte (“FDN”) gold mine in southeast Ecuador . Notable conversion drilling results at Fruta del Norte South ("FDNS")
confirmed the deposit’s continuity and identified additional mineralized zones. Mine engineering studies are underway
aiming to integrate the FDNS deposit into the FDN long term mine plan. Concurrently, further high-grade results at FDN
East continue to underscore the target’s substantial growth potential. Highlights from the drilling programs at FDNS and
FDN East are outlined below. Detailed results can be found in Appendix 1.
Ron Hochstein, President and CEO, commented, “Conversion drilling on FDNS continues to yield some of the highest-grade
results to date alongside the discovery of a new mineralize d vein that lies outside the existing inferred resource . With
significant advances in our engineering studies, we remain on track to integrate a portion of the FDNS mineralization in
FDN’s long-term mine plan, just a year since its maiden resource announcement . In addition, recent drill results at FDN
East continue to underscore its excellent exploration potential , located in close proximity to our existing underground
development.”
FDNS Conversion Drilling Highlights (not true widths):
• Drill hole FDN -C25-238 intersected 139.53 grams per tonne (“g/t”) of gold (“Au”) over 9.05m from 62.20m,
including:
o 1,720 g/t Au over 0.70m
• Drill hole FDN-C25-234 intersected 220.32 g/t Au over 4.20m from 93.70m, including:
o 520.18 g/t Au over 1.75m
• Drill hole FDN-C25-245 intersected 43.77 g/t Au over 9.85m from 102.70m, including:
o 74,70 g/t Au over 3.80m
• Drill hole FDN-C25-205 intersected 31.63 g/t Au over 8.10m from 38.60m, including:
o 101.35 g/t Au over 1.40m
These conversion drilling results have confirmed the continuity of the mineralization at FDNS, with several higher -grade
zones identified within the deposit. High -grade drill holes outside the current geological model demonstrate significant
potential for further resource expansion. In addition, engineering studies are progressing well with the objective of
integrating FDNS into FDN’s long-term mine plan.
FDN East Drilling Highlights (not true widths):
• Drill hole UGE-E-25-207 intersected 6.61 g/t Au over 10.00 m from 497.15m including:
o 13.16 g/t Au over 3.95 m
• Drill hole FDNE-2025-279 intersected 11.52 g/t Au over 3.10m from 170.65m, including:
o 23.80 g/t Au over 1.30m
Drill results at FDN East have successfully expanded gold mineralization along the north extension and indicated potential
areas for further growth.

DRILLING PROGRAMS
The Company’s near -mine exploration strategy focuses on extending the mine life at FDN through the expansion of
Mineral Resources and the delineation of new discoveries in close proximity to the operation. Over the past three years,
exploration programs at FDN have significantly contributed to resource growth and successfully discovered new
mineralized sectors. In recent months, the near mine underground drilling has prioritized the FDNS Mineral Resource
conversion while simultaneously advancing exploration along the extensions of FDNS and at FDN East.
The 2025 drilling program is currently estimated to be a minimum of 108,000 metres consisting of 83,000 metres of
exploration drilling and 25,000 metres of conversion drilling. Seventeen rigs are currently turning across the conversion
and near-mine exploration programs.
FDNS
Since January, the underground drilling program at FDNS has focused on converting Inferred Mineral Resources to the
Indicated category. The objective of the conversion program is to integrate the deposit into FDN’s long-term mine plan
in 2026. The program also continues to explore distinct sectors within FDNS. Delineated in 2024, the FDNS deposit is an
epithermal vein system located along the southern limit of FDN, currently estimated to contain an Inferred Resource of
approximately 2.09 million ounces ( Moz) from 12.35 million tonnes (Mt) with an average grade of 5.25 g/t. For more
information on the FDN Mineral Reserve and Resource estimate as at December 31, 2024, please refer to the Company’s
Annual Information Form dated March 17, 2025 (the “AIF”) under the Company’s profile at www.sedarplus.ca.
During the second quarter , the conversion drilling program completed a total of 7,085 metres of underground drilling
across 50 drill holes . The majority of these drill holes confirmed mineralization continuity with several outstanding
intercepts which defined higher-grade zones within the vein system (see Figure 1 and 2). Notably drill holes FDN-C25-238
(139.53 g/t Au over 9.05m) and FDN-C25-234 (220.32 g/t Au over 4.20m) represent some of the highest-grade intercepts
ever recorded at FDNS. Assay results from the drilling undertaken at FDNS are presented in Table 1.
The conversion drill holes also indicate additional gold mineralization extending beyond currently defined zones .
Highlights include drill hole FDN-C25-205 (31.63 g/t Au over 8.10m) which is related to a mineralized zone in the central
portion of FDNS (See Figure 2). In the eastern limit , drill hole FDN-C25-227 (18.86 g/t Au @ 9.60m) revealed a new
mineralized vein that lies outside the existing inferred resource, indicating further expansion potential towards the south
(See Figure 1 and 2). Three underground rigs are currently dedicated to the conversion drilling program at FDNS.
The FDNS deposit remains open for expansion along its north and south extensions. Since June, three rigs have been
exploring the expansion potential of the deposit with several exploration drill holes completed during this period with
assays pending.
Mine planning work is underway on FDNS to evaluate geotechnical, mine design, metallurgical characteristics and
infrastructure needs with the goal of integrating the Mineral Resource estimate at FDNS into FDN’s updated long -term
mine plan.

FDN EAST
At FDN East, the exploration program continues to define and expand this new buried epithermal mineralized system
located only 100 metres east of FDN. Since its discovery, the drilling program has advanced our understanding of the main
geological controls, leading to the delineation of subparallel mineralized veins oriented north to south in the central part
of the target (see Figure 3).
The most recent drilling results intercepted the continuity of this new system in the north ern portion of the sector,
indicating promising areas for further expansion potential (Figure 3). Highlights include drill holes UGE-E-25-207 (4.84 g/t
Au over 3.05m and 6.61 g/t Au over 10.00m) and drill hole FDNE-2025-279 (11.52 g/t Au over 3.10m), which confirm that
mineralization remains open along the north extension . Assay results from the drilling undertaken at FDN East are
presented in Table 2. Currently, one underground rig is turning at FDN East.
