Andina Copper Intersects 164m at 0.70% Cu, 0.44g/t Au within 468m at 0.50% Cu, 0.30g/t Au in initial discovery drilling at Piuquenes North
Andina’s Piuquenes North assays confirm a third porphyry with 468m at 0.50% Cu and a high-grade core.

Andina Copper Corporation (ANDC) has released assay results from two diamond drill holes, PIU12 and PIU13, at the Piuquenes North target in San Juan, Argentina. This initial drilling targeted a large magnetotelluric (MT) anomaly.
Hole PIU13 intersected a broad mineralized interval of 468 m averaging 0.50% Cu, 0.30 g/t Au, and 3.04 g/t Ag from 700 m depth. This included a higher-grade core of 164 m at 0.70% Cu, 0.44 g/t Au, and 4.19 g/t Ag from 924 m. Hole PIU12, drilled 600 m east-northeast, encountered only peripheral mineralization, consisting of 14 m at 0.38% Cu.
The company interprets these results as confirming a new multiphase porphyry copper-gold system, which adds a third center to the Piuquenes district. The MT anomaly, measuring 800 m by 700 m, remains largely untested, and follow-up drilling is currently being designed.
Andina Copper Corporation (ANDC), a pre-revenue explorer with a market capitalization of approximately $304 million, announced a new porphyry discovery that the company considers material. The assay results, while positive, are not expected to dramatically re-rate the deposit. Previous drilling at Cobrasco yielded higher-grade intercepts, and the stock has previously traded at higher levels, reaching $1.43.
Market sentiment appeared to anticipate positive assays from Piuquenes North following the visual discovery in May. The stock’s subsequent pullback to $1.13 suggests that expectations had cooled prior to the announcement. The reported intercept of 164 meters at 0.70% copper with gold is likely to serve as a positive catalyst. However, due to the depth of the hole, a lack of true width, and the weak performance of the step-out hole, the result is not considered transformational.
Andina Copper Corporation (TSX-V: ANDC) is a South America-focused copper explorer that holds three projects: the Cobrasco Cu-Mo porphyry in Colombia, the Piuquenes Cu-Au porphyry district in Argentina, and the Mantau early-stage Cu-Au target in Chile. The Piuquenes district contains three known centers: Central, East, and North.
The company currently has no revenue and relies on equity financing, having raised $27.5M in early 2026. Drilling at Cobrasco and Piuquenes has generated news flow, but no resource estimates have been produced yet.
