Sendero Resources (TSX‑V:SEND) has reported drilling results from its reconnaissance program at the Peñas Negras Project in Argentina.
Three diamond holes totalling 396.3m were completed on the southwestern margin of the target area, with all holes returning near‑surface gold and silver mineralisation.
Hole PNDH‑201 returned 1.04 grams per tonne gold (Au) over 1.5m from 14.0m, within a broader halo of elevated gold grades extending from surface to 46.0m.
The same hole delivered 48g/t silver (Ag) over 1.5m from 14m and 28.2g/t Ag over 1m from 57m.
The drilling confirmed Sendero’s porphyry‑epithermal geological model and identified multiple pathfinder elements including antimony, arsenic, copper, molybdenum, lead, and zinc, reinforcing the presence of a significant hydrothermal system.
“These results provide strong validation of our geological model for Peñas Negras. This important step forward in defining the district scale potential of our strategic land package,” CEO Alex Gostevskikh says.
“The three holes completed to date, together with historical Anglo American drilling, confirm the presence of a substantial high-sulphidation epithermal system, although its full dimensions remain to be defined.”
An extensive leached cap was identified in all three holes, considered integral to a significant high‑sulphidation epithermal system. The full lateral and vertical extent remains to be determined.
The Penas Negras project covers 211.77km² in the Vicuna belt, approximately 12km north‑northeast of the Josemaria resource area.
Sendero Resources is a Canadian junior explorer focused on copper-gold exploration in Argentina’s Vicuña Belt.
