VANCOUVER, BC, Aug. 5, 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. Recent drilling at Trancaloma has confirmed the continuity and expanded the at surface copper-gold porphyry system. Additionally, drilling at Sandia, approximately four kilometres ("km") to the north of Trancaloma, has uncovered a new copper-gold porphyry system with mineralization beginning at surface, establishing a highly prospective exploration corridor adjacent to FDN. Highlights from the Trancaloma and Sandia drilling programs are outlined below, with detailed results provided in Appendix 1. PDF Version
LUNDIN GOLD EXPANDS TRANCALOMA MINERALIZATION AND DISCOVERS NEW COPPER-GOLD PORPHYRY SYSTEM AT SANDIA (CNW Group/Lundin Gold Inc.)
Ron Hochstein, President and CEO, commented, "We are very pleased to report these additional exciting drill results from our 2025 program, which continue to demonstrate the significant untapped exploration potential around FDN. Follow-up drilling at Trancaloma has successfully confirmed the continuity of the at surface copper-gold mineralization and indicates further expansion potential. The discovery of a new copper-gold porphyry system at Sandia, which also hosts mineralization at surface, further defines an emerging and highly prospective porphyry corridor currently delineated as 5 km long and adjacent to FDN."
Trancaloma Drilling Highlights (not true widths):
Drill hole TRL-2025-290 intersected 667.1m of 0.44% CuEq (0.32% Cu, 0.12 g/t Au, 2.61 g/t Ag, and 17.21 ppm Mo) from 367.5 m, including:
226.0m of 0.58% CuEq (0.41% Cu, 0.16 g/t Au, 5.09 g/t Ag, and 14.03 ppm Mo)
Drill hole TRL-2025-272 intersected 876.7m of 0.34% CuEq (0.27% Cu, 0.07 g/t Au, 1.07 g/t Ag, and 22.7 ppm Mo) from 0.00 m, including:
272.7m of 0.50% CuEq (0.40% Cu, 0.12 g/t Au, 1.47 g/t Ag, and 11.29 ppm Mo)
Results confirm the lateral and vertical continuity of the Trancaloma system, extended the main mineralized zone, and provided areas for further expansion.
Sandia Drilling Highlights (not true widths):
Drill hole SND-2025-298 intersected 730.9m of 0.35% CuEq (0.28% Cu, 0.06 g/t Au, 1.39 g/t Ag, and 27.79 ppm Mo) from 0.0 m, including:
35.7m of 0.57% CuEq (0.49% Cu, 0.05 g/t Au, 2.28 g/t Ag, and 42.45 ppm Mo)
153.0m of 0.43% CuEq (0.35% Cu, 0.07 g/t Au, 1.85 g/t Ag, and 19.84 ppm Mo)
With the discovery of another copper-gold porphyry system, a highly prospective near mine corridor adjacent to the epithermal gold deposits has emerged.
NEAR MINE EXPLORATION PROGRAM-TARGETING NEW DISCOVERIES
The near-mine exploration program continues to build on the unique potential of Lundin Gold's world class land package with 2025 being the largest drilling program ever conducted on the land package that hosts FDN. One of the key components of this program is the scout drilling targeting unexplored sectors within this highly potential geological environment. This year, the near-mine drilling program has already completed more than 48,000 metres of drilling and the majority has been dedicated to finding new mineral deposits in new sectors.
A POTENTIAL PORPHYRY CORRIDOR IS EMERGING
Since the discovery of FDN, the occurrence of porphyry systems has been recognized around FDN with limited exploration carried out. In 2025 a systematic program of geochemical and geophysical surveys, geological mapping, and scout drilling has defined a 5 km long corridor with significant potential for porphyry-type deposits adjacent to the gold epithermal systems that host FDN. The first drill holes in this program completed on this corridor resulted in the discovery of the Trancaloma and Sandia systems, with other potential sectors remaining to be tested (See Figure 1).
TRANCALOMA
Following the initial discovery of Trancaloma earlier this year, the Company initiated a systematic step-out drilling program. This program has successfully extended the main copper-gold mineralized zone and confirms continuous mineralization from surface, with a wide, higher-grade core that remains open in all directions and at depth.
The Trancaloma mineralization is characterized by a well-developed and zoned porphyry related hydrothermal alteration, with chalcopyrite and pyrite associated with quartz (B-veins), magnetite and chalcopyrite veins, and disseminated sulfides. Drill hole TRL-2025-290 (667.1m @ 0.44% CuEq [0.32% Cu, 0.12 g/t Au], incl. 226.0m @ 0.58% CuEq [0.41% Cu, 0.16 g/t Au]) demonstrated wide intervals of sulfide-rich brecciated zones, suggesting shallow potential for expansion along the northwestern direction.
In the western portion of Trancaloma, exploratory drill hole TRL-2025-291 confirmed another copper-gold mineralized zone that remains open (see Figure 2). The most recent assay results from the drilling program undertaken at Trancaloma are presented in Table 3. Currently, three surface drill rigs are exploring Trancaloma.
SANDIA
Located less than two kms east of FDN and four kms north of Trancaloma, the Sandia target was tested by a drill hole focused on a wide geochemical soil copper-gold-molybdenum anomaly. The drilling successfully intercepted shallow copper-gold mineralization from surface, confirming another porphyry system (see Figure 1 and 3).
The mineralization is associated with typical porphyry zoning and hydrothermal alteration, containing variable amounts of chalcopyrite and pyrite with quartz (B-veins) throughout the entire length of the hole. This system remains open in all directions. A second drill hole was concluded along the down-dip extension with assays pending. Currently, two surface drill rigs are exploring Sandia.

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 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.
