Andina Copper Extension Drilling Intersects 198 m at 0.51% Cu, 78 ppm Mo within 454 m at 0.43% Cu, 66 ppm Mo
Executive Summary
- Andina Copper reported a significant intercept from hole CDH005, confirming a large southerly extension of the Cu‑Mo‑Ag mineralized system at its Cobrasco Project.
- The drillhole tested ~600 m laterally and 700 m vertically, terminating at 934 m depth, with all reported mineralized intervals applying a 0.2 % Cu cut‑off.
- Step‑out holes CDH006 and CDH007 have been completed (assays pending) and drilling of hole CDH008 is underway to target the northern extension of the system.
Key Details
- Hole CDH005 – Collared on the same platform as previous holes (CDH002‑CDH004), oriented due south (Az 180°, Dip –50°).
- Tested ~600 m of lateral extent and ~700 m of vertical extent; terminated at a downhole depth of 934 m.
- Intersected mineralized diorite to dacite‑andesite porphyries with visible chalcopyrite‑dominant sulphide mineralization.
- Mineralization remains open to the south; no phreatomagmatic breccias observed (contrast to earlier SW‑trending holes).
-
All reported intercepts use a 0.2 % Cu cut‑off and maximum dilution of 10 m.
-
Geological Highlights – Presence of intermediate intrusive phases consistently mineralized over broad intervals; transition from quartz‑rich rhyolitic/dacitic subvolcanic dome complex to intermediate dacite‑andesite porphyries.
-
Drilling Program Status
- CDH006 & CDH007: Step‑out holes completed, assays pending.
- CDH008: Currently underway, targeting northern extension of the Cu‑Mo system.
-
Overall systematic drilling has defined mineralization over a ~2 500 m × 1 000 m target area; to date ~1 000 m × 750 m tested (less than half the potential footprint).
-
Assay & QA/QC – Core extracted with HQ/NQ drill strings, sampled at nominal 2 m intervals, processed by ALS laboratories in Medellín and Lima for Au, multi‑elements, and Cu analyses.
-
Environmental Work – Baseline environmental program initiated across the project area; further geological mapping and surface sampling planned to support ongoing targeting.
Notable Quotes
“Ongoing drilling at Cobrasco continues to demonstrate the large‑scale and relatively shallow nature of Cobrasco Central… we see the potential for a globally significant copper deposit(s) at Cobrasco.” – Joseph van den Elsen, President & CEO
Materiality Assessment: Material – Positive (the drill results materially expand the known mineralized envelope, indicating significant upside to the project’s resource potential).
