(TSX-V:ANDC) (FSE:FIR) (OTCQB:PMMCF) For Immediate Release
February 5, 2026 – Vancouver, British Columbia.
Andina Copper Corporation ( TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) is pleased to report
assay results for its maiden diamond dril lhole CDH003 at the Cobrasco copper -molybdenum
project located in the Chocó Department, Colombia.
Since commencing field exploration in early October 2025, the Company has completed a total
of three diamond drill holes for 2609 m, with a fourth hole currently underway.
HIGHLIGHTS:
• CDH003 intersected significant copper mineralization from surface to final depth (774.8m).
High-grade intersections include1:
352 m @ 0.68% Cu, 112 ppm Mo, 1.55 g/t Ag (0.78% CuEq2) from 144 m;
Incl. 118 m @ 1.17% Cu, 193 ppm Mo, 2.35 g/t Ag (1.33% CuEq) from 246 m
• Drilling continues at Cobrasco, with 3 holes completed to date for 2609 m.
• CDH004 and CDH005 were completed to depths of 900 m and 934 m respectively, with
assay results for CDH004 expected shortly.
• Drill rig mobilized to a platform ~410 m NW of CDH005 and 390 m SW of CDH001.
• Surface reconnaissance along the northern extensions of the minerali zed trend ha s
confirmed outcrops of early-stage A-type stockwork veining and limonites after sulphides,
over 1km from the area currently being drilled.
• Sporadic gold mineralization reported in CDH003, suggestive of a possible gold rich
intrusive phase within the broader Cobrasco system.
Andina Copper’s President and CEO Joseph van den Elsen commented:
“These exceptional assay results from our very first drillhole validate Cobrasco as a globally
significant Cu-Mo porphyry system and clearly demonstrate potential for large tonnages of high-
grade mineralization. Ongoing drilling is expected to further expand the multi-kilometer footprint
of mineralization both northward and south along the well-defined structural corridor.

2026 promises to be an exciting time for Andina Copper shareholders, as we are now in a catalyst
rich period with strong, exploration driven news flow being generated across all three of our
projects. The 2025-26 field season is well underway at Piuquenes and exploration is continuing
at pace at Cobrasco, with results from CDH004 expected shortly. Follow-up exploration will also
shortly commence at Mantau.”

Assay results for CDH004 are expected shortly, with samples from CDH005 to be dispatched
imminently to the ALS laboratory in Medellin.
CDH006 has been mobilized and gradual step -outs will continue in a NW direction, testing the
areas of known mineralization and enlarging the mineralization footprint laterally and vertically
with increased drilling.

Geology and Mineralization CDH003
Drilling at Cobrasco was resumed on hole CDH003, previously suspended at 300.60 m by Rugby
Resources in late 2022, and continued to a final depth of 774.80 m.
Hole CDH003 was originally designed to test a near-surface mineralized intercept in hole CDH001
at depth and drilled some 325 m vertically underneath CDH001. Significant copper mineralization
continued to the end of hole, with an unconstrained interval of 0.37% Cu (0.44% CuEq) from
surface to 774.80 m.
The upper portions of CDH 003 (up to 66 m) are marked by several early pulses of intermediate
porphyry types. These intrusions are generally dark-coloured due to their elevated mafic content
and disseminated magnetite commonly exceeding 1% . Crowded porphyritic textures are
consistent with deeper emplacement and slower cooling. These units may represent remnants of
roof pendants of the early intermediate porphyry units.
Later phases of light -coloured felsic porphyries including rhyolite, rhyodacite, dacite and
granodiorite have been identified at increasing depth. They typically display an open texture
characterized by aphanitic and locally vitreous groundmass, commonly containing diagnostic
large quartz phenocrysts. Microscopic features observed in these lithologies , including aphanitic
groundmass with flow banding and fractured phenocrysts , are indicative of rapid magma
decompression and related to the emplacement of a dome complex.
At a depth of 640 m, dark coloured, fine-grained andesitic subvolcanic lithologies were
encountered in sheared contact with felsic porphyries. This interval marks the first appearance of
ANDINA COPPER 5
what are interpreted to be the La Equis Formation andesite host sequence intersected in the
drilling. These intermediate volcanic units of Lower Eocene age were intruded by the main Mande
Batholith and associated family of porphyry units, which characteristically occur as flow dome
complexes along the western margins of the batholith.
The central portion of the drill hole is characteri zed by an early rhyolite porphyry which exhibits
strong magmatic -hydrothermal brecciation and is a preferred host for high-grade copper
mineralization assayed in CDH003.
Mineralization at Cobrasco is controlled by multiple, recurrent hydrothermal events associated
with the emplacement and subsequent progressive cooling of the intermediate to felsic porphyry
intrusions, consistent with the evolution of a large porphyry system. Potassic alteration is well-
developed in both , intermediate and felsic porphyries, and multiple generations of veining ,
including A-type early quartz veins and B-type quartz-molybdenite veins. The creation of a dense
network of microfractures and dissolution voids resulted in the necessary space for the invasion
and subsequent precipitation of Cu-bearing fluids, principally chalcopyrite in veinlets and infills in
what has been classified as C-type veins.
Chalcopyrite and bornite occur as veinlets, disseminations, fracture fillings and, locally, as breccia
infill. Bornite commonly replaces chalcopyrite and is typically associated with pervasive green -
grey sericite alteration. Later anhydrite -chalcopyrite veins crosscut both intermediate and felsic
porphyry phases, with veins ranging from a few centimetres to tens of centimetres. Where closely
spaced, these veins can define metre-scale zones of elevated Cu grades (refer Fig 3).
Strong A- and B-type early veining observed in multiple outcrops on the northern reaches of the
concessions, are associated with Cu and Mo soil and rock geochemical anomalism. Veining
associated with ubiquitous outcropping iron oxides after sulphides (limonites) and high copper
rock grades (>0.5% Cu) was observed, confirming an extension of the rhyolite-dacite intrusive
dome complex and known mineralization over a kilometer from the location of current drilling.
Such targets will be followed up in the short-term, in preparation of mobilizing a second drill rig.

QAQC
CDH003 was collared with a HQ size, with drill core extracted from the core tubes by the drill
contractor under the supervision of Andina Copper, marked for consistent orientation and
placed in core boxes with appropriate depth markers added. Full core boxes were then sealed
before being transported by Andina Copper to the Cobrasco core-cutting facility in Quibdó. Core
was processed, quick logged, checked for recovery, photographed, and marked for assays.
Core trays were weighed before being cut using a diamond saw by Andina Coppper. Andina
Copper supervising geologist double-checked the selected two-meter sample intervals, placed
the samples in sealed bags ,and ensured that the same side of the core was consistently
sampled. Reference numbers were assigned to each sample and each sample was weighed.
The core trays with the remaining half-core were weighed and photographed and are stored at
the Andina Copper facility in Quibdó. From Quibdó samples were sent to the ALS preparation
facility in Medellin, an accredited laboratory which is independent of the Company. Prepared
samples were then sent to the ALS laboratory in Lima, Peru for gold (Au-AA23), copper (Cu-
OG62), and multi-element ICP (ME-MS61) analysis. No data quality issues were detected by
the QA/QC program.
