Exploration History
Figure 2
- Privately held, minimal exploration since initial drilling in 1990’s
- Inmet Mining (acquired by First Quantum 2013) completed 1,900m of drilling in late 90’s. Cu-Au intersections included:
- 413.5m from 167m @ 0.47% Cu, 0.52 g/t Au
- 158m from 3m @ 0.32% Cu, 0.60 g/t Au
- Anglo American single 920m drill hole in 2016 reported:
- 558.2 m from 362m @ 0.38% Cu, 0.42 g/t Au, 2.4 g/t Ag
- Incl. 180m @ 0.71% Cu, 0.61 g/t Au, 3.8 g/t Ag.
- Pampa Metals completed 3 drill holes (2,592m) in the 23/24 field season. High grade Cu-Au intersections included:
- 801m from 54m @ 0.40% Cu, 0.51 g/t Au, 2.87 g/t Ag
- Incl. 518m @ 0.53% Cu, 0.73 g/t Au, 3.45 g/t Ag

- 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 potential
- 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 database and initial 3D geology and mineralization models produced Drill hole data was combined with surface geology, geochemistry and geophysics and re-interpreted
Key findings:
- Data suggests a northeast trend to the Piuquenes system with the potential for a cluster of deposits
- The Piuquenes Central deposit is defined in geophysics by a distinct resistivity high. 1km to the south-east at Piuquenes East, a similar magnitude resistivity anomaly is considered a standout target
- Outside of the Piuquenes Central and Piuquenes East targets, the tenement package has not been subject to any systematic exploration
