VANCOUVER, BC, Nov. 3, 2025 /CNW/ - Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) (OTCQX: LUGDF) ("Lundin Gold" or the "Company") is pleased to announce positive results from its near-mine exploration drilling programs at its 100% owned Fruta del Norte ("FDN") gold mine in southeast Ecuador.
Highlights from drilling programs at Sandia, Trancaloma, and Castillo are outlined below, with detailed results provided in Appendix 1.
Ron Hochstein, President and CEO, commented, "I am pleased to announce additional exciting drill results from Lundin Gold's 2025 drilling program, which highlight significant exploration potential along the recently discovered porphyry systems trend. The latest results not only confirm the continuity of mineralization at Sandia and Trancaloma but also indicate a much larger scale porphyry system along this main corridor. The discovery of higher-grade intervals at Sandia and Castillo is meaningful and highlights further opportunities within these large porphyry systems for both additional scale and higher grade. Seventeen rigs, eleven on surface and six underground, are currently turning on our exploration programs and a minimum of 108,000 metres of drilling will be completed in 2025, representing the largest drilling program ever conducted on the land package that hosts FDN".

SANDIA-TRANCALOMA CORRIDOR - LARGE SCALE EXPLORATION POTENTIAL
Since the recognition of the exploration potential for copper gold porphyry mineralization late last year, an extensive and systematic program employing geochemical and geophysical surveys, geological mapping, and scout drilling resulted in the discovery of a large porphyry intrusive complex with shallow wide mineralized zones recognized in distinct sectors. The most advanced discoveries, Trancaloma and Sandia, together currently define a five kilometre continuous corridor that hosts additional unexplored targets exhibiting porphyry type hydrothermal alteration associated with geochemical anomalies and reveals a much larger scale exploration potential than previously recognized along this trend (See Figure 1 and 2).
SANDIA
Located less than two kilometres northeast from FDN, Sandia sits in the north of the main porphyry corridor and is represented by shallow, continuous copper gold mineralization with higher grade zones. It remains open for expansion in all directions. Since the discovery only a few months ago (see press release dated August 5, 2025), all completed step out drill holes in the period confirmed a continuous mineralized zone for almost 1,000 metres along the northwestern strike, 500 metres width and 800 metres at depth (See Figures 1, 2 and 3).
The Sandia copper gold mineralization is mainly represented by A-type quartz (chalcopyrite) ± magnetite veinlets hosted mainly by quartz monzonite porphyry with a well-developed K-feldspar-magnetite alteration. A highlight to the program thus far is drill hole SND-2025-335 (606.70m @ 0.59% CuEq [0.49% Cu, 0.10 g/t Au]) that intercepted a shallow and wide mineralized zone and indicates that the mineralization remains open along the east and west directions. Also of note, drill hole SND-2025-326 (202.0m @ 0.90% CuEq [0.75% Cu, 0.18 g/t Au]) returned the highest-grade interval ever intercepted on these porphyry systems and suggests further exploration potential toward the north. The most recent assay results from the drilling program undertaken at Sandia are presented in Table 1. Currently, three surface drill rigs are exploring at Sandia.
TRANCALOMA
Since the discovery of Trancaloma earlier this year, drilling has defined a wide and continuous copper gold mineralized zone at surface that extends for almost 1,000 metres along northwestern strike, 650 metres width and 1,000 metres at depth (See Figures 1, 2 and 4).
The mineralization at Trancaloma is a well zoned porphyry related hydrothermal alteration, with the phyllic zone upward represented by sericitic alteration and chlorite-sericite-pyrite chalcopyrite alteration transitioning at depth to the potassic zone represented by K-feldspar, biotite and magnetite alteration and A-type quartz ± magnetite veining. The drill holes TRL-2025-315 (774.60m @ 0.38% CuEq [0.30 % Cu, 0.09 g/t Au], incl. 270.90m @ 0.60% CuEq [0.47% Cu, 0.15 g/t Au]) and TRL-2025-319 successfully expanded the limits of the mineralized zone, which remains completely open for growth along the northwestern direction toward the Sandia porphyry.
On the western side of Trancaloma, now named Trancaloma West, the drill hole TRL-2025-307 (512.40m @ 0.38% CuEq [0.30 % Cu, 0.09 g/t Au] incl. 100.65m @ 0.63% CuEq [0.49% Cu, 0.16 g/t Au]) confirmed another copper-gold mineralized zone for further step out. The most recent assay results from the drilling program undertaken at Trancaloma are presented in Table 1. Currently, two surface drill rigs are exploring Trancaloma.
CASTILLO
At Castillo, located two kilometres south of FDN and along the west border of Bonza Sur, the drilling program intercepted a shallow high grade copper gold mineralization covered by approximately 100 metres of conglomerates of the Suarez Basin (see Figure 1). The drill hole CAS-2025-329 (224.15m @ 0.71% CuEq [0.57% Cu, 0.19 g/t Au], incl. 35.55m @ 2.79 % CuEq [2.12% Cu, 0.92 g/t Au]) showed high values of copper and gold associated with intervals of massive quartz-magnetite-chalcopyrite veining and highlight significant exploration potential in this sector. The most recent assay results from the drilling program undertaken at Castillo are presented in Table 1. Currently, one surface drill rig is exploring Castillo.
Qualified Persons and Technical Notes
The technical information contained in this News Release has been reviewed and approved by Andre Oliveira, P. Geo, Vice President, Exploration of the Company, who is a Qualified Person in accordance with the requirements of National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
Samples consist of half HQ and NQ-size diamond core that are split by diamond saw on site, prepared at the ALS laboratory in Quito, and analyzed by 50g fire assay and multi-element (ICP-AES/ICP-MS) at the ALS Laboratory in Lima, Peru. The quality assurance-quality control (QA-QC) program of Lundin Gold includes the insertion of certified standards of known gold content, blank and duplicate samples. The remaining half core is retained for verification and reference purposes. For further information on the assay, QA-QC, and data verification procedures, please see Lundin Gold's most recent Annual Information Form ("AIF").
Copper equivalent (CuEq) for drill intersections is calculated based on US$4.00/lb Cu, US$1,800/oz Au, US$30/oz Ag. and US$25/oz Mo. The formula is: CuEq % = Cu % + (0.6562 * Au g/t) + (0.0109 * Ag g/t) + (0.0006 * Mo ppm). Metallurgical recoveries and net smelter returns are not considered.
