Nobel Resources identifies copper system at Cuprita

Executive Summary

• Nobel Resources Corp. has identified a new mineralized copper porphyry system at its Cuprita project in northern Chile, marking the first diamond drill program on this highly prospective target.
• Drill hole CUP004 intersected over 100 meters of copper-bearing mineralized porphyry, with significant portable XRF readings indicating high-grade copper potential within a sulphide-rich interval.
• The discovery is underpinned by the identification of an extensive lithocap (silica-rich matrix with pyrite boxwork) over an area of at least 1,000m x 300m, which serves as a key geological signature for porphyry copper systems in the region.

Key Details

• Drill Hole CUP004 Intercepts:
  • Intersected more than 100 metres of copper-bearing, mineralized porphyry.
  • 218m depth: Marked increase in tourmaline veins; rock transitions into intrusive breccia with porphyry clasts.
  • Breccia Zone: Portable XRF copper values up to 1,700 ppm (parts per million).
  • 285.5m to 382m: Sulphide-rich interval characterized by increasing density of quartz-sulphide veins, disseminated pyrite, chalcopyrite, and locally bornite.
  • Alteration: Sericite-chlorite with moderate to strong intensity.
  • High-Grade XRF Readings: Copper values up to 2.9% in chrysocolla-bearing veinlets and 2.6% Cu in pyrite-chalcopyrite veinlets within the 285.5m–382m interval.
  • 382m to 408.8m: Post-mineralization dike, barren of sulphide minerals.
  • Below 408.8m: Weakly mineralized porphyry intercepted.
  • Total Depth: Hole stopped at 460.6 metres.
• Drill Hole CUP003:
  • First hole to appear to clip the edge of the system.
  • Intercepted weakly mineralized porphyry.
  • Provided important vectors based on alteration observed.
• Geological Context & Lithocap:
  • Target area centered around an extensive lithocap identified via surface mapping in 2025.
  • Lithocap characteristics: Strongly silicified rock, resistant silica-rich matrix, abundant cavities from leaching, pyrite boxwork textures.
  • Lithocap dimensions: Mapped over at least 1,000 metres in length and 300 metres in width.
  • Potential extent: Access road construction revealed outcrops beyond mapped dimensions; actual extent possibly extends over 2km by 1km under overburden.
  • Soil Anomaly: Cu values above 200 ppm, reaching a maximum of 9,000 ppm Cu in soils.
• Geological Assumptions & Targeting:
  • Located within the Paleocene porphyry copper belt.
  • Presence of extensive leach cap (lithocap) commonly associated with porphyry copper deposits.
  • Extensive tourmaline breccia zones identified as pathfinders.
  • Induced polarization anomaly and magnetic low associated with target area.
  • Structural setting similar to major regional deposits (El Salvador, Cerro Colorado, Spence, Sierra Gorda, Fortuna).
  • Vertical alteration zoning confirmed in CUP-003 and CUP-004: transitioning from argillic to phyllic and propylitic alteration.
• Technical Notes:
  • Portable XRF measurements are point-source estimates for drill hole planning and are not representative of average grade; full assays are pending.
  • XRF analyzer calibrated for altitude and activated with standardization coin check sample.
• Quality Assurance/Quality Control (QA/QC):
  • Samples collected over 1-2 metre intervals.
  • Certified reference materials, blanks, and duplicates inserted systematically (1 standard per 20 samples; 1 blank/duplicate per 50 samples).
  • Samples transported by company personnel to Andes Analytical Assays (independent lab) in compliance with NI 43-101.
• Qualified Person:
  • David Gower, PGeo, reviewed and approved the scientific and technical information.

Notable Quotes

• "Based on my over 35 years of exploring in the Chile for these types of deposits, it is very rare to find such an extensive new lithocap with associated mineralization and geophysical anomalies that has never been drilled. This is an exciting start to the program." — Vernon Arseneau, Chief Operating Officer of Nobel
