Andina Copper Corporation (TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) has reported another outstanding drill intercept from hole CDH006 at its Cobrasco Project in Chocó, Colombia. The hole, collared on a new step-out drill pad approximately 400 meters northwest of previous pads, was designed to test the northwest extension of the mineralized system. Assay results confirm continuity of the Cobrasco Central Cu-Mo mineralization system, with near-surface mineralization commencing at 38 meters within weathered saprolite and continuing through multiple anomalous intervals in rhyodacitic porphyries to a faulted contact at 808 meters.
Highlights from CDH006 include 486 meters at 0.42% Cu, 51ppm Mo, and 1.20g/t Ag, including 336 meters at 0.51% Cu, 53ppm Mo, and 1.50g/t Ag, and further including 232 meters at 0.68% Cu, 75ppm Mo, and 2.0g/t Ag from 38 meters. This intercept demonstrates the high-grade nature of the mineralization near surface. Two additional step-out drillholes, CDH007 and CDH008, have been completed from the same drill platform testing extensions to the northeast and north, with assays pending.
Andina Copper’s President and CEO Joseph van den Elsen commented: “Every scout drillhole completed to-date has intersected significant intervals of Cu-Mo mineralization, further extending the mineralization footprint. This footprint now covers an area of at least 950 x 525 meters within the emerging Cobrasco Central mineralization.” He added that broadly spaced, systematic scout drilling will continue to define the limits of mineralization, which remains open in all directions, and to test newly developed targets. Preparations are also underway for the mobilization of a second drill rig to support both definition of new mineralized targets and in-fill drilling across the widely spaced scout holes completed to date.
The geology of CDH006 reveals a clear association between structural controls and mineralization. The upper 46 meters are strongly weathered saprolites, with a low-angle fault structure marking the introduction of high copper and molybdenum grades (e.g., sample G517536: 46-48m at 4.6% Cu, 1495ppm Mo). Below this, more competent rhyolite and rhyodacite units host quartz-sulphide veining and brecciation, with alteration progressing from argillic to phyllic and grey-green-sericite (GGS). A zone of magmatic brecciation extends to 270 meters, characterized by increased A-veins and high Cu-Mo grades. The interval from 38 to 270 meters contains the standout intercept of 232 meters at 0.68% Cu and 75ppm Mo.
The Company’s ongoing drilling program continues to expand the known mineralization footprint, which already covers a lateral extent of approximately 950 x 525 meters within the upper 600 meters and remains open in all directions. A new program of surface mapping and geochemical sampling is being prepared to run concurrently with drilling, intended to delineate multiple targets for follow-up sampling and drilling.

The technical information in this news release has been reviewed and approved by Francisco Montes, a consultant of Andina Copper Corp and a Qualified Person as defined in National Instrument 43-101. The QAQC procedures for drillhole CDH006 included PQ size drill string to 138m, continued with HQ/HQ3 to 678.10m, and completed with NQ/NQ2 to 898.90m. Core samples were sent to ALS preparation facility in Medellin and subsequently to ALS laboratory in Lima, Peru for analysis. The Company holds significant discoveries along the Andean porphyry belt in Argentina and Colombia, and a copper-gold target in Chile.
