Located in La Rioja province, highlights include:
-
Upcoming 3,600m Phase II drill program to test a porphyry-type undrilled target with favorable structural, geochemical, and geophysical signatures.
-
Structurally-defined 3.0 by 2.0 km tract marked by structures, alteration patterns, and distinctive minor intrusions.
-
Numerous datasets assembled and integrated to generate a predictive-discovery exploration model in congruence with the district geology and deposits – mineral systems approach; clearly indicating a well-endowed region.
-
The model establishes the foundation for building a pipeline of exploration targets on Sendero’s sizeable land position in the Vicuña Belt. Aligned with the mineralizing trends responsible for major neighbouring deposits, confirming the district-scale potential of Peñas Negras.
Sendero Resources Corp. provided a strategic update for its Peñas Negras Project in the Vicuña Belt, which a series of world-class copper-gold discoveries, including Filo del Sol, Josemaría, and Lunahuasi. Sendero’s Peñas Negras Project occupies a propitious position inside the structural corridor where these deposits occur, sharing common geological settings and ease of access advantages.
Sendero successfully executed Phase I of its exploration program, which comprised 3,126 meters of core drilling in eight holes, 715 line kilometers of airborne magnetics and radiometrics, 10 square kilometers of IP lines, and 211 line kilometers of ground magnetics surveys. This work generated results which significantly raised the accuracy of structural interpretation and decidedly demonstrated presence of both porphyry and epithermal mineralization on the property, as is common at other deposits in the Vicuña Belt.
“2025 has been a transformative year for Sendero. With Phase 1 now complete, we have multiple high-quality targets in one of the newest and well-endowed gold-copper belts in the world,” said Alex Gostevskikh, Chief Executive Officer of Sendero Resources. “Our focus now shifts to drilling – the stage where true value is created. We believe Peñas Negras gives our shareholders rare exposure to the next discovery potential provides our shareholders with rare exposure to the next potential discovery in the Vicuña Belt”.
Some of the best drilling results of Phase 1 are outlined below:
-
Hole PNDH-001 at La Pena intersected 226 metres grading 0.22 g/t AuEq from surface;
-
Hole PNDH-002 at Tamberias intersected 168 metres grading 0.22 g/t AuEq from surface;
-
Hole PNDH-003 at La Ollita intersected 256 metres grading 0.53 g/t AuEq from 84 m;
-
Hole PNDH-004 at La Ollita intersected 266 metres grading 0.52 g/t AuEq from 96 m;
-
Hole PNDH-05 at La Ollita intersected 300 m grading 0.36 g/t AuEq from 122 m;
-
Hole PNDH-06 at La Ollita intersected 364.2 m grading 0.51 g/t AuEq from 33.8m;
The Company completed district-wide data integration and analysis and conducted a field program late 2024 and in January-February 2025 to ascertain geological settings, collect rock specimens for referencing remote spectral and magnetic data, and review historical core logs. These activities were an essential part of a re-compilation of geophysical, geochemical, spectral, drilling, trenching, and structural data and development of an integrated database for the Company’s areas of interest, as well as adjacent land packages.
