Project Overview

Piuquenes is located in San Juan, Argentina, within the Central Andes Miocene Porphyry Belt — one of the world’s premier copper–gold porphyry districts, and ranked the #1 mining jurisdiction in Latin America by the Fraser Institute (2019). The project sits in a zone that hosts some of the world’s largest copper deposits and is surrounded by Tier-1 projects operated by major mining companies. This exceptional geological setting makes Piuquenes a standout address for copper exploration.

Tier 1 Location

Central Andes Miocene Porphyry Belt, San Juan Province (Argentina).

Immediately adjacent to giant >2Bt Altar deposit.

Proximate to some of the world’s biggest copper deposits:

  • Los Pelambres (Antofagasta PLC) – 335–350 Kt Cu annual production.
  • Los Azules (McEwen Mining) – 2.1 Bt @ 0.40% Cu.
  • Altar (Aldebaran Resources) – 2.40 Bt @ 0.42% Cu, 0.07 g/t Au, 1.22 g/t Ag.
  • El Pachón (Glencore) – 1.6 Bt @ 0.55% Cu.

Region consistently ranked as a top global mining jurisdiction (Fraser Institute).

Drilling to Date

7.1 km of diamond drilling has been completed across 8 holes (PIU-01 to PIU-08) at Piuquenes Central and Piuquenes East, confirming a gold-rich porphyry Cu system at Central and a second porphyry system at East.

Standout intercepts – Piuquenes Central (Cu-Au):

  • PIU-03: 801 m @ 0.40% Cu, 0.51 g/t Au, 2.87 g/t Ag from 54 m, incl. 518 m @ 0.53% Cu, 0.73 g/t Au.
  • PIU-01: 422 m @ 0.48% Cu, 0.61 g/t Au, incl. 132 m @ 0.71% Cu, 0.85 g/t Au.
  • PIU-02: 448 m @ 0.42% Cu, 0.46 g/t Au, incl. 126 m @ 0.66% Cu, 0.74 g/t Au.
  • PIU-05 (step-out): 152 m @ 0.40% Cu, 0.23 g/t Au from 530 m (hole to 1,104.5 m).
  • PIU-08 (step-out): 570 m @ 0.39% Cu, 0.24 g/t Au from 188 m, incl. 298 m @ 0.54% Cu, 0.39 g/t Au.
  • (Historical re-assay): 558.2 m @ 0.38% Cu, 0.42 g/t Au from 362 m, incl. 180 m @ 0.71% Cu, 0.61 g/t Au.

New discovery – Piuquenes East (Cu-Au):

  • PIU-06 (maiden hole): 208 m @ 0.31% Cu, 0.13 g/t Au from 292 m, incl. 98 m @ 0.49% Cu, 0.16 g/t Au.

Geological significance:

  • Central: Gold-rich porphyry with bornite present, >800 m vertical extent, mineralization open in multiple directions.
  • East: Stand-alone porphyry–breccia system less than 1 km from Central. Multi-phase alteration with SCC/phyllic/advanced argillic overprints, open north, west, and east.

Andina Copper’s Maiden Drill Program

  • 3 diamond drill holes completed in Q2 2024 confirmed:
    • Highly significant Cu grades well above global average for new Cu projects.
    • Multi-phase system with intense porphyry A type quartz stockwork hosting chalcopyrite and bornite copper mineralization.
    • Presence of abundant bornite indicates significant potential for underlying bornite rich core to deposit.
  • Defined dimensions to date at Piuquenes Central ~350 x 250 x 800m (SW-NE-Depth).
  • High-grade Cu and Au open to depth in multiple directions, indicative of significant upside potentia.
  • Gold rich porphyry system.
  • Strong gold endowment, largely co-incident with copper mineralization.
  • Gold mineralization from surface. Historical drill hole DDH02 intersected 0.32% Cu, 0.6 g/t Au in oxidized rock from surface to end of hole at 161m.
  • Gold grades >0.5g/t delineated over 800m of vertical extent with coherent >0.7g/t Au high-grade core from ~200-600m open.
  • Gold and copper mineralization remains open in multiple directions.

Significant Upside

All available historical technical data has been compiled into an integrated geological model. This highlights Piuquenes as a district-scale porphyry system with multiple untested targets.

Key Upside Potential:

  • Possible deposit cluster: Desktop data confirms a northeast trend indicating multiple porphyry centres across the property.
  • Piuquenes East – standout new target: An outcropping porphyry stockwork with a 400 × 300 m Cu–Au soil anomaly, intermediate chargeability, and resistivity features—drilling is now underway.
  • Electrical geophysical anomalies: IP, resistivity, and MT surveys define high chargeability and resistivity zones at both Central and East, including buried pipe-like resistivity features—excellent first-pass targeting for new centres.
  • Larger, underexplored land package: The tenement area was expanded (~34%), but most of it remains without systematic exploration—field mapping and targeting are just beginning.
  • Bornite-rich core potential: Drilling at Central shows multi-phase mineralization with bornite presence, indicating the potential for a higher-grade core well at depth.
