  • Geometallurgical test results indicate good copper liberation, low pyrite association, and favorable metallurgical recoveries, validating the technical potential of the ore under operating conditions.
  • The updated resource estimate is expected in September, while complete Cu-Au assay results will be available by the end of August.
  • Some of the main intercepts in quartz-diorite porphyry are shown in Table 1, with significant copper and gold grades.
  • Andean Belt Resources engaged SRK Consulting to develop a Preliminary Economic Assessment (PEA) in accordance with NI 43-101 standards.
  • The QP, Mr. Jose Luis Bello Soto, confirms that the scientific and technical content of this news release has been reviewed and approved.

Statistics:

  • 12 diamond drill holes were executed in the 2025 drilling campaign, totaling 5,810 meters.
  • The updated resource estimate is due in September.
  • 20% of the geochemical results have been received.
  • Average recoveries of 92.6% Cu and 74.9% Au were achieved in rougher flotation tests.
