Lundin Gold Discovers Two New Copper-Gold Porphyries and Targets Early 2027 Maiden Resource Estimate for Sandia Porphyry
Lundin Gold Inc. announced continued success from its copper-gold porphyry exploration programs at its 100%-owned Fruta del Norte district in southeast Ecuador. Following the discovery of Sandia in 2025 and continued drilling success across the district, the Company now targets a maiden mineral resource estimate for the Sandia copper-gold porphyry in early 2027, marking an important milestone in advancing the first of the Company's identified porphyry systems toward the resource stage. Recent drilling continues to expand the Sandia deposit while also resulting in the discovery of two new mineralized porphyry systems, Sandia Northeast and Sandia Southeast, increasing the number of porphyry centres identified across the Fruta del Norte district from five to seven. Drilling at Sandia Northeast and Sandia Southeast has identified two additional copper-gold porphyry systems, increasing the total number of porphyry discoveries on the Fruta del Norte concessions to seven. The deposit footprint has now grown to approximately 1,600 m strike x 700 m width x 1,000 m depth and remains open to the north, east and at depth. Sandia is currently the largest and highest-grade porphyry system identified on the Fruta del Norte concessions. Sandia Maiden Resource Estimate is targeted for early 2027. Drill hole SND-2026-502 intersected 0.42% Cu, 0.08 g/t Au, 1.62 g/t Ag, and 17.05 ppm Mo (0.50% CuEq) over 551.30 m from 67.00 m, including 0.51% Cu, 0.11 g/t Au, 1.71 g/t Ag, and 14.14 ppm Mo (0.61% CuEq) over 307.95 m. Drill hole SND-2026-510 intersected 0.38% Cu, 0.06 g/t Au, 1.93 g/t Ag, and 39.06 ppm Mo (0.46% CuEq) over 909.45 m from 29.00 m, including 0.45% Cu, 0.08 g/t Au, 2.38 g/t Ag, and 34.05 ppm Mo (0.56% CuEq) over 401.10 m. Drill hole SND-2026-498 intersected 0.22% Cu, 0.11 g/t Au, 0.82 g/t Ag, and 9.97 ppm Mo (0.31% CuEq) over 454.00 m from 278.70 m, including 0.26% Cu, 0.14 g/t Au, 0.90 g/t Ag, and 8.74 ppm Mo (0.37% CuEq) over 236.75 m. Drill hole TRL-2026-439 intersected 0.22% Cu, 0.05 g/t Au, 1.43 g/t Ag, and 19.20 ppm Mo (0.28% CuEq) over 172.40 m from 254.25 m, including 0.31% Cu, 0.07 g/t Au, 1.82 g/t Ag, and 14.84 ppm Mo (0.38% CuEq) over 52.45 m. Located approximately two kilometres from Fruta del Norte, Sandia is the Company's most advanced porphyry discovery and is expected to become the first porphyry system on the Fruta del Norte concessions to support a mineral resource estimate. Drilling has now outlined a mineralized footprint measuring approximately 1,600 metres along strike, 700 metres in width and 1,000 metres vertically, while remaining open to the north, east and at depth. Recent drilling continues to expand the deposit and reinforce confidence in the geological model. In the northern sector of the deposit, drill hole SND-2026-502 extended the higher-grade domain and indicates further growth potential in that direction. In the central portion of the system, drill hole SND-2026-510 expanded mineralization to the east and at depth. A total of 16,920 metres in 24 drill holes has now been completed at Sandia. Geological modelling is underway and all drilling results received to date are being incorporated into the model that will support the maiden mineral resource estimate targeted for early 2027. Four drill rigs are currently active at Sandia. Located approximately 500 metres northeast of Sandia, scout drilling testing a large Cu-Mo geochemical anomaly has led to the discovery of a new copper-gold porphyry system. The broad mineralized interval intersected in drill hole SND-2026-498 is associated with characteristic porphyry-style potassic alteration and A-type quartz veining, supporting the interpretation of another mineralized porphyry centre within the Sandia area. One drill rig is currently active at Sandia Northeast. Sandia Southeast is located between the Sandia and Trancaloma deposits in a previously undrilled area. Recent drilling intercepted copper-gold mineralization associated with a porphyry-style hydrothermal alteration and supports the interpretation of another mineralized porphyry centre within the district. The sector highlights the exploration potential of the area between the two deposits and provides another target for follow-up drilling.
