Andina Copper (TSX‑V:ANDC) has intersected 206m @ 0.67% copper (Cu) from 32m within a broader interval of 400m @ 0.46% Cu at its Cobrasco porphyry copper‑molybdenum discovery in Choco, Colombia.
Hole CDH011 confirms the vertical continuity of mineralisation within the central portion of the Cobrasco system.
The ‘higher‑grade’ upper zone extends to 276m downhole, while moderate‑grade copper‑molybdenum mineralisation continues to approximately 592m downhole.
The 400m interval @ 0.46% Cu also returned 60ppm molybdenum and 1.1 grams per tonne silver (Ag) from 32m.
‘Higher‑grade’ subintervals include 40m @ 0.87% Cu and 70 parts per million (ppm) molybdenum (Mo) from 32m, and 54m @ 0.76% Cu and 59ppm Mo from 184m. Below the ‘higher‑grade’ zone, CDH011 intersected an additional 290m @ 0.25% Cu and 93ppm Mo from 302m.
“All 11 drill holes reported at Cobrasco have intersected significant near-surface copper-moly mineralisation, with CDH011 including one of the highest-grade near-surface intervals to date of 206m at 0.67% copper,” CEO Joseph van den Elsen says.
The initial 11 diamond holes reported to date have delineated a mineralised footprint of approximately 1,200m by 550m to 700m, which remains open in multiple directions.
Andina is advancing a wide‑spaced scout drilling program using substantial step‑outs to test the extent and limits of the mineralised system. A second drill rig is expected to mobilise shortly to accelerate the evaluation.
Andina Copper holds two significant discoveries along the Andean porphyry belt in Argentina and Colombia, and a copper‑gold target in Chile’s Coastal Cordillera.
