Andina Copper Reports 620 m @ 0.45% Cu, 79 ppm Mo from

62 m, including 146 m @ 0.76% Cu, 107 ppm Mo

(TSX-V:ANDC) (FSE:FIR) (OTCQB:PMMCF) For Immediate Release

February 17, 2026 – Vancouver, British Columbia.

Andina Copper Corporation (TSX -V: ANDC | FSE: FIR | OTCQB: PMMCF) is pleased to report

outstanding drill intercepts from the second hole of its maiden diamond drilling program at the

Company’s Cobrasco copper-molybdenum project in Chocó, Colombia.

Following on from the recent high-grade copper-molybdenum intersections in drillhole CDH003

(352m @ 0.68% Cu, 112 ppm Mo; Incl. 118m @ 1.17% Cu, 193 ppm Mo (refer News Release

dated 5 February 2026 )), results from subsequent drillhole CDH004 have reported further

intercepts of strong mineralization.

HIGHLIGHTS:

• Significant wide intercepts of Cu-Mo mineralization reported in drillhole CDH004:

• Sporadic occurrences of gold mineralization of up to 1.06 g/t in CDH004 support a

possible gold-rich intrusive phase within the broader Cobrasco system.

• Strong copper mineralization logged in drillhole CDH005. CDH005 was designed to

expand the mineralized footprint to the southwest of holes CDH003 and CDH004 and

completed to 934.00m. Results expected shortly.

• Step-out d rillhole CDH006 targeting potential for large extensions of the mineralized

system currently underway.

• Potential for a large -scale porphyry Cu-Mo deposit with significant volumes of high-

grade mineralization evident, supported by ongoing drilling and geological observations.

Andina Copper’s President and CEO Joseph van den Elsen commented:

“Following recent results from CDH003, the wide intercepts of high -grade copper mineralization

reported in CDH004 further validate the size, scale and grade of the Cobrasco system. We see

the potential for a globally significant deposit(s) at Cobrasco, and mobilization of a second drill rig

to expedite rapid exploration and evaluation is planned. Ongoing step-out drilling will now seek to

systematically expand the footprint of the system, add volume to the copper grade shells an d

define the lateral extents of the system”.

Geology and Mineralization CDH004

Following the successful completion of drillhole CDH003, which returned long intercepts of high -

grade copper-molybdenum mineralization (refer Table 1: Cobrasco Significant Drill Intercepts ),

hole CDH004 was completed to a final depth of 900.25 m.

CDH004 was collared from the same platform as CDH002 and CDH003 but oriented to the south-

west (Az: 225°, Dip: -60°) to drill in-section, broadly parallel to CDH001 and the surface soil grid

and IP geophysics, and to cross-cut the dominant regional NW structural trend.

The upper 56 m intersected a sequence of intermediate composition porphyries characterized by

disseminated magnetite, a characteristic dark color due to the mafic content, and crowded crystal

textures consistent with deeper emplacement and slower cooling. The lower portion of this interval

(44–56 m) returned anomalous copper and silver values of up to 0.39% Cu and 393 ppm Ag.

From 56 to 579 m, CDH004 intersected multiple phases of early to late -mineral rhyolite,

rhyodacite and dacite with felsic affinities. These units display glassy aphanitic groundmass,

quartz phenocrysts (“quartz eyes”) and local flow banding, interpreted to reflect rapid magma

decompression and emplacement within a flow -dome complex. The felsic sequence is cut by

multiple thin intermediate composition porphyry intrusions that are mineralized and demonstrate

favorable host rock characteristics.

The interval from 579 to 686 m contains the strongest copper grades and is associated with

intensely fractured magmatic-hydrothermal breccias. These intermineral breccias are interpreted

to have developed along contacts between successive porphyry phases and above early

intermineral intrusions. They comprise a fine -grained igneous matrix hosting sub -angular

fragments of earlier porphyries and vein clasts. The intense fracturing suggests effective fluid

focusing, making this interval a significant contributor to the mineralized system. The breccia zone

returned an average grade of 0.75% Cu over the 579–686 m interval, including a peak 2 m assay

value of 1.70% Cu.

The final interval from 686 m to end of hole at 900.25 m is characterized by phreatomagmatic

breccias displaying tuffaceous matrix with juvenile crystal fragments and polymict clast

assemblages with poor sorting. These are interpreted as a late-stage event in the genesis of the

deposit and returned comparatively low copper grades, averaging 215 ppm Cu, with a maximum

2 m value of 0.20% Cu. Similar late-mineral phreatomagmatic breccias were recognized at depth

in CDH001 and are considered low -grade to barren, and will represent a boundary or delimiting

lithology unit for ongoing drill planning.

Geology and Mineralization CDH005 (assays pending)

CDH005 was collared from the same drill pad as holes CDH002 – CDH004 (Az: 180°, Dip: -50°)

as a shallow-angle, deep hole designed to test the southern extensions of the Cobrasco Central

mineralized system and evaluate the geological controls on magnetic response and host lithology.

Unlike the earlier holes, CDH005 targeted an area characterized by high magnetic intrusive

sequences at surface, transitioning into a magnetic low embayment at depth. To date, stronger

mineralization has been associated with felsic intrusive host rocks (predominantly rhyolites and

ANDINA COPPER 4

rhyodacites) displaying coincident magnetic lows, making this hole an important test of both

southern continuity and exploration model assumptions.

The hole was collared within intermediate diorite porphyry (as described for CDH004) and

remained within this phase to approximately 170 m downhole before intersecting fine -grained

dacite–andesite intrusive units. These subvolcanic porphyries exhibit visua lly significant

chalcopyrite-dominant sulphide mineralization, accompanied by weak to moderate sericitic

alteration overprinting earlier potassic assemblages — consistent with mineralized porphyry

systems observed elsewhere within the district.

The dacite–andesite units are intruded by thin apophyses of intermineral rhyolite porphyry and

extend to approximately 630 m downhole, where the hole intersected a younger intermineral

rhyolite porphyry that continued to end of hole at 934 m. The lower sec tions display epidote –

chlorite alteration consistent with a propylitic assemblage, interpreted to represent the outer zones

of the Cobrasco Central hydrothermal system.

The continuity of intrusive phases, alteration styles and sulphide mineralization throughout the

hole supports the interpretation of a large and long -lived mineralizing system extending south of

the currently defined drill footprint.

Detailed geological and geotechnical logging is ongoing, with assays pending and expected

shortly.

QAQC

CDH004 was collared with a HQ size drill string, with drill core extracted from the core barrel by

the drill contractor under the supervision of Andina Copper personnel and placed in core boxes

with appropriate depth markers and padding added. Full core boxes were then sealed before

being transported by helicopter and pickup truck to the Cobrasco core-cutting facility in Quibdó.

Core was cleaned, marked-up and photographed, prior to undergoing the required geotechnical

and geological logging. All core was c ut by diamond saw by Andina Copper technicians, other

than the top saprolite intervals that could be cut by spatula. All sampling was conducted in nominal

2m intervals and in all cases, the cut -line was marked by the supervising geologists to ensure

representative sampling. Samples were placed in plastic bags with non -repeatable sample tags

and bagged in polyweave bags ready for transport.

The core trays with the remaining half-core are stored at the Andina Copper facility in Quibdó for

ongoing geotechnical (Terraspec spectral analysis, magsus magnetic measurements, density

measurements and follow-up detailed geological logging. From Quibdó core samples were sent

to the ALS preparation facility in Medellin, an accredited laboratory which is independent of the

Company. Prepared sample pulps were then sent to the ALS laboratory in Lima, Peru for gold

(Au-AA23), multi-elements (ME-MS61), and overlimits limits analysis (ME-OG62 including copper

Cu-OG62). Coarse and fine rejects are returned by ALS Medellin for storage at the Andina Copper

storage facility.
