Mineros S.A. Reports Initial Results from 2026 Diamond Drilling Campaign At Nicaragua Property
Mineros S.A. reported initial results from its 2026 diamond drilling campaign at the Nicaragua Property. Results cover four target areas: Xiloa in the Pioneer Mine environs; the Leticia and Apoyo vein systems in the Porvenir Polymetallic District; La Reforma at the Pioneer Mine; and infill delineation at the Panamá Mine. The 2026 campaign is Mineros' most intensive drilling program to date at the Nicaragua Property, with 75,000 metres planned with ten rigs operating simultaneously, eight company-owned and two contracted. The program drives new-target drilling at Xiloa, step-out drilling at Leticia and La Reforma, and infill delineation at Panamá and Pioneer. The Xiloa Vein System was delineated by surface mapping and sampling as part of the Company's brownfield exploration program and drill-tested for the first time in 2026. Xiloa is located approximately 1.2 kilometres northeast of the active Pioneer Mine. The first hole drilled in 2026, BXIDDH_26_001, returned 8.3 m at 17.3 g/t Au and 11.9 g/t Ag from 329.7 m depth (including 0.6 m at 58.7 g/t Au and 25.9 g/t Ag). Follow-up holes BBONDD_26_0053 (5.2 m at 6.7 g/t Au and 11.2 g/t Ag) from 206.0 m depth and BBONDD_26_0051 (2.2 m at 6.2 g/t Au and 9.2 g/t Ag) from 212.8 m depth confirm lateral continuity of the mineralization. The five holes drilled to date preliminarily define the Xiloa zone over approximately 400 metres of strike length and 150 metres of vertical extent; the system remains open laterally and at depth in all directions. Step-out drilling at Xiloa will continue through the second and third quarters of 2026, with holes targeting strike and depth extensions of the high-grade mineralization identified. Table 1. Xiloa Target – 2026 Initial Drilling Results: BXIDDH_26_001: 329.7-338.0 m, 8.3 m, 17.3 g/t Au, 11.9 g/t Ag; including 332.9-333.6 m, 0.6 m, 58.7 g/t Au, 25.9 g/t Ag. BBONDD_26_0053: 205.9-211.1 m, 5.2 m, 6.7 g/t Au, 11.2 g/t Ag; including 209.2-209.7 m, 0.5 m, 16.7 g/t Au, 14.0 g/t Ag. BBONDD_26_0054: 381.2-381.7 m, 0.5 m, 6.5 g/t Au, 5.8 g/t Ag. BBONDD_26_0051: 212.8-215.0 m, 2.2 m, 6.2 g/t Au, 9.2 g/t Ag; including 214.2-214.6 m, 0.4 m, 20.7 g/t Au, 15.6 g/t Ag. BBONDD_26_0052: 331.6-336.5 m, 4.9 m, 3.7 g/t Au, 4.5 g/t Ag; including 334.5-335.5 m, 1.0 m, 8.2 g/t Au, 5.9 g/t Ag. The Porvenir Polymetallic District is one of the most significant growth platforms within the Mineros Nicaragua Property — an emerging epithermal gold-silver-zinc system where recent exploration has defined a district-scale mineralized corridor spanning multiple spatially related deposits and targets. The district currently supports approximately 736 Koz AuEq in Proven and Probable Mineral Reserves, 406 Koz AuEq in Measured and Indicated Mineral Resources (exclusive of Mineral Reserves), and a further 313 Koz AuEq in the Inferred Resource category. The Leticia and Apoyo vein systems, located less than 500 metres from the Porvenir Project, represent the leading edge of that expansion. The 2026 program has returned high-grade intercepts across three vein systems within the district. At Leticia, hole BLDDH_26_050 returned the strongest results, intersecting 1.2 m at 271.3 g/t Au and 80.7 g/t Ag from 90.8 m depth and, deeper in the same hole, 1.9 m at 74.6 g/t Au (including 0.9 m at 133.0 g/t Au and 28.1 g/t Ag) from 218.6 m. At the Leticia North footwall splay, hole BLDDH_26_052 returned 1.5 m at 20.4 g/t Au and 7.9 g/t Ag from 85.4 m depth (including 0.6 m at 55.2 g/t Au and 21.1 g/t Ag) and hole BLDDH_26_051 cut 0.9 m at 16.4 g/t Au and 13.9 g/t Ag from 69.1 m depth. At the Apoyo Vein System, hole BAPDDH_26_011 intersected 0.9 m at 3.6 g/t Au and 20.0 g/t Ag from 231.1 m depth, and hole BAPDDH_26_013 returned 5.9 m at 3.0 g/t Au and 10.3 g/t Ag from 232.0 m depth. All three vein systems remain open along strike and at depth. Table 2. Porvenir Polymetallic District – Leticia North, Leticia and Apoyo Vein Systems – 2026 Drilling Results: BLDDH_26_050: 90.8-92.0 m, 1.2 m, 271.3 g/t Au, 80.7 g/t Ag, Leticia. BLDDH_26_052: 85.5-87.0 m, 1.5 m, 20.4 g/t Au, 7.9 g/t Ag, Leticia North; including 86.5-87.0 m, 0.5 m, 55.3 g/t Au, 21.1 g/t Ag. BLDDH_26_051: 69.1-70.1 m, 0.9 m, 16.4 g/t Au, 13.9 g/t Ag, Leticia North. BLDDH_26_051: 72.4-73.7 m, 1.2 m, 3.2 g/t Au, 5.3 g/t Ag, Leticia North. BLDDH_26_050: 218.6-220.6 m, 1.9 m, 74.6 g/t Au, 15.6 g/t Ag, Leticia (New Split); including 218.6-219.6 m, 0.9 m, 133.0 g/t Au, 28.1 g/t Ag. BLDDH_26_051: 312.0-313.4 m, 1.4 m, 2.8 g/t Au, 18.5 g/t Ag, Leticia. BAPDDH_26_011: 231.0-231.9 m, 0.9 m, 3.6 g/t Au, 20.0 g/t Ag, Apoyo. BAPDDH_26_013: 232.0-237.8 m, 5.9 m, 3.0 g/t Au, 10.3 g/t Ag, Apoyo; including 237.1-237.8 m, 0.7 m, 4.2 g/t Au, 2.8 g/t Ag. BAPDDH_26_012: 174.9-176.3 m, 1.4 m, 3.4 g/t Au, 8.7 g/t Ag, Apoyo; including 175.8-176.3 m, 0.5 m, 8.1 g/t Au, 16.4 g/t Ag. Step-out drilling at Pioneer Mine is systematically extending the La Reforma vein system below its current resource boundary, and advancing the mineralized corridor at depth, while a focused infill drilling campaign at Panamá Mine is tightening drill spacing across known ore blocks. Step-out drilling at the La Reforma Vein System is delivering compelling results at depth. Hole BLRDDH_26_003 cut 1.5 m at 15.3 g/t Au and 14.0 g/t Ag from 213.4 m within the La Reforma NE structure. Supporting step-out holes BPIODD_26_2267 (1.4 m at 11.3 g/t Au and 12.1 g/t Ag) from 261.0 m depth and BLRDDH_26_002 (2.2 m at 5.1 g/t Au and 30.1 g/t Ag from 287.0 m depth, including 0.7 m at 8.2 g/t Au) together extend the La Reforma mineralization by approximately 100 metres at depth. Infill drilling within the main La Reforma vein continues to return results consistent with the established grade distribution. Holes BPIODD_26_2270 (0.9 m at 6.4 g/t Au and 16.0 g/t Ag from 183.8 m depth), BPIODD_26_2271 (2.0 m at 4.5 g/t Au and 4.5 g/t Ag from 449.1 m depth, including 0.5 m at 14.0 g/t Au and 12.8 g/t Ag), and BPIODD_26_2272 (1.1 m at 4.3 g/t Au and 9.9 g/t Ag from 223.7 m depth). Infill drilling at the Panamá Mine is tightening drill spacing across the Capitán FW and Atlas vein corridors, with the objective of converting Inferred Mineral Resources to the Indicated Mineral Resource classification and providing the data density required to support Mineral Reserve estimation. Hole BPANUDD_26_1171 returned 4.4 m at 8.9 g/t Au and 78.6 g/t Ag from 250.5 m depth — including a high-grade core of 1.0 m at 18.4 g/t Au and 122.0 g/t Ag — and hole BPANUDD_26_1172 intersected 2.4 m at 8.3 g/t Au and 31.8 g/t Ag from 270.8 m depth, including 0.6 m at 24.0 g/t Au and 47.3 g/t Ag. Both intercepts confirm the grade continuity expected within the active mining blocks.
