Mineros S.A. reported initial results from its 2026 diamond drilling campaign at the Nicaragua Property, highlighting a new high‑grade vein system at the Xiloa target and confirming exceptionally high grades at the Leticia vein system. The data, released by the company’s Vice President of Exploration, underscores ongoing resource expansion efforts within the existing mining infrastructure.
Mineros Announces New High‑Grade Vein System at Xiloa
The 2026 drilling program intersected an 8.3 m core at Xiloa delivering 17.3 g/t Au and 11.9 g/t Ag from 329.7 m depth, including a 0.6 m sub‑interval of 58.7 g/t Au and 25.9 g/t Ag. Follow‑up holes (BBONDD_26_0053 and BBONDD_26_0051) returned 5.2 m at 6.7 g/t Au and 2.2 m at 6.2 g/t Au, confirming lateral continuity. To date, five holes define the zone over roughly 400 m of strike and 150 m of vertical extent, with the system open in all directions. Located 1.2 km northeast of the active Pioneer Mine, Xiloa sits within reach of existing roads and processing facilities, positioning it as a near‑term resource addition.
Step‑out drilling will continue through Q3 2026 to test strike and depth extensions. Mineros plans a total of 75,000 m of drilling this year, operating ten rigs (eight owned, two contracted) at a reported cost below $100 / m, among the lowest in Latin America.
Leticia Vein System Confirms Exceptional Grades
At the Leticia target, hole BLDDH_26_050 intersected 1.2 m of 271.3 g/t Au and 80.7 g/t Ag from 90.8 m depth, and a deeper 1.9 m of 74.6 g/t Au (including 0.9 m of 133.0 g/t Au) from 218.6 m depth—both reported as uncut. Additional intercepts at the Leticia North footwall splay (0.9 m at 16.4 g/t Au) define a new structural corridor open along strike. These results reinforce the high‑grade nature of the Porvenir Polymetallic District, which already supports approximately 736 Koz AuEq in Proven and Probable reserves and 406 Koz AuEq in Measured and Indicated resources.
Infill and Step‑Out Drilling Bolsters Existing Mine Plans
Infill drilling at Panamá Mine returned 4.4 m at 8.9 g/t Au and 78.6 g/t Ag from 250.5 m depth, including a 1.0 m high‑grade core of 18.4 g/t Au and 122.0 g/t Ag, confirming grade continuity within current mining blocks. At Pioneer Mine, step‑out holes in the La Reforma vein system extended mineralization 100 m deeper, with a 1.5 m intercept of 15.3 g/t Au and 14.0 g/t Ag from 213.4 m depth.
These campaigns aim to increase mineral resource confidence near existing operations, extend main vein systems, and test brownfield targets across the 151,389‑hectare land package.
Key Takeaways
- Xiloa’s initial hole returned 8.3 m at 17.3 g/t Au, defining a new high‑grade vein system open in all directions and located 1.2 km from Pioneer Mine infrastructure.
- Leticia delivered a 1.2 m intercept of 271.3 g/t Au, confirming exceptionally high grades within the Porvenir Polymetallic District.
- Infill drilling at Panamá Mine showed 4.4 m at 8.9 g/t Au and 78.6 g/t Ag, supporting grade continuity for near‑term reserve estimation.
EnergyInsyte's Take
The results expand Mineros’ near‑term resource base while leveraging existing infrastructure, which could streamline future development timelines. However, true vein widths remain unknown and the grades are reported uncut, so additional work will be needed to convert these intercepts into measured resources and reserves. Executives should monitor the upcoming step‑out results at Xiloa and the ongoing infill program at Panamá for clearer indications of reserve growth and mine‑plan integration.
