Andina Copper Reports 620 m @ 0.45% Cu, 79 ppm Mo from 62 m, including 146 m @ 0.76% Cu, 107 ppm Mo
(TheNewswire)
February 16, 2026 – TheNewswire - Vancouver,British Columbia. Andina Copper Corporation(TSX-V: ANDC | FSE: FIR | OTCQB: PMMCF) is pleased to reportoutstanding drill intercepts from the second hole of its maidendiamond drilling program at the Company’s Cobrasco copper-molybdenumproject in Chocó, Colombia.
Following on from the recent high-gradecopper-molybdenum intersections in drillhole CDH003 (352m @ 0.68% Cu, 112 ppmMo; Incl. 118m @ 1.17% Cu, 193 ppm Mo (refer News Releasedated 5 February 2026)), results fromsubsequent drillhole CDH004 have reported further intercepts of strongmineralization.
HIGHLIGHTS:
Significant wide intercepts of Cu-Momineralization reported in drillhole CDH004:
Sporadic occurrences of goldmineralization of up to 1.06 g/t in CDH004support a possible gold-rich intrusive phase within the broaderCobrasco system.
Strong copper mineralization loggedin drillhole CDH005. CDH005 was designed toexpand the mineralized footprint to the southwest of holes CDH003 andCDH004 and completed to 934.00m. Results expected shortly.
Step-out drillhole CDH006targeting potential for large extensions of themineralized systemcurrentlyunderway
Potential for a large-scale porphyryCu-Mo deposit withsignificant volumes of high-grade mineralization evident, supported by ongoing drilling and geologicalobservations.
Andina Copper’s President and CEO Joseph van denElsen commented:
“Following recent results fromCDH003, the wide intercepts of high-grade copper mineralizationreported in CDH004 further validate the size, scale and grade of theCobrasco system. We see the potential for a globally significantdeposit(s) at Cobrasco, and mobilization of a second drill rig toexpedite rapid exploration and evaluation is planned. Ongoing step-outdrilling will now seek to systematically expand the footprint of thesystem, add volume to the copper grade shells and define the lateralextents of the system”.

Geology and MineralizationCDH004
Following the successful completion of drillholeCDH003, which returned long intercepts of high-grade copper-molybdenummineralization (refer Table1: Cobrasco Significant Drill Intercepts), holeCDH004 was completed to a final depth of 900.25 m.
CDH004 was collared from the same platform as CDH002and CDH003 but oriented to the south-west (Az: 225°, Dip: -60°) todrill in-section, broadly parallel to CDH001 and the surface soil gridand IP geophysics, and to cross-cut the dominant regional NWstructural trend.
The upper 56 m intersected a sequence of intermediatecomposition porphyries characterized by disseminated magnetite, acharacteristic dark color due to the mafic content, and crowdedcrystal textures consistent with deeper emplacement and slowercooling. The lower portion of this interval (44–56 m) returnedanomalous copper and silver values of up to 0.39% Cu and 393 ppmAg.
From 56 to 579 m, CDH004 intersected multiple phases ofearly to late-mineral rhyolite, rhyodacite and dacite with felsicaffinities. These units display glassy aphanitic groundmass, quartzphenocrysts (“quartz eyes”) and local flow banding, interpreted toreflect rapid magma decompression and emplacement within a flow-domecomplex. The felsic sequence is cut by multiple thin intermediatecomposition porphyry intrusions that are mineralized and demonstratefavorable host rock characteristics.
The interval from 579 to 686 m contains the strongestcopper grades and is associated with intensely fracturedmagmatic-hydrothermal breccias. These intermineral breccias areinterpreted to have developed along contacts between successiveporphyry phases and above early intermineral intrusions. They comprisea fine-grained igneous matrix hosting sub-angular fragments of earlier porphyries and vein clasts. The intensefracturing suggests effective fluid focusing, making this interval asignificant contributor to the mineralized system. The breccia zonereturned 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 900.25m is characterized by phreatomagmatic breccias displaying tuffaceousmatrix with juvenile crystal fragments and polymict clast assemblageswith poor sorting. These are interpreted as a late-stage event in thegenesis of the deposit and returned comparatively low copper grades,averaging 215 ppm Cu, with a maximum 2 m value of 0.20% Cu. Similarlate-mineral phreatomagmatic breccias were recognized at depth inCDH001 and are considered low-grade to barren, and will represent aboundary or delimiting lithology unit for ongoing drillplanning.

Geology and Mineralization CDH005(assays pending)
CDH005 was collared from the same drill pad as holesCDH002 – CDH004 (Az: 180°, Dip: -50°) as a shallow-angle, deephole designed to test the southern extensions of the Cobrasco Centralmineralized system and evaluate the geological controls on magneticresponse and host lithology.
Unlike the earlier holes, CDH005 targeted an areacharacterized 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 hostrocks (predominantly rhyolites and rhyodacites) displaying coincidentmagnetic lows, making this hole an important test of both southerncontinuity and exploration model assumptions.
The hole was collared within intermediate dioriteporphyry (as described for CDH004) and remained within this phase toapproximately 170 m downhole before intersecting fine-graineddacite–andesite intrusive units. These subvolcanic porphyriesexhibit visually significant chalcopyrite-dominant sulphidemineralization, accompanied by weak to moderate sericitic alterationoverprinting earlier potassic assemblages — consistent withmineralized porphyry systems observed elsewhere within thedistrict.
The dacite–andesite units are intruded by thinapophyses of intermineral rhyolite porphyry and extend toapproximately 630 m downhole, where the hole intersected a youngerintermineral rhyolite porphyry that continued to end of hole at 934 m.The lower sections display epidote–chlorite alteration consistentwith a propylitic assemblage, interpreted to represent the outer zonesof the Cobrasco Central hydrothermal system.
The continuity of intrusive phases, alteration stylesand sulphide mineralization throughout the hole supports theinterpretation of a large and long-lived mineralizing system extendingsouth of the currently defined drill footprint.
Detailed geological and geotechnical logging isongoing, with assays pending and expected shortly.

QAQC
CDH004 was collared with a HQ size drill string, with drill coreextracted from the core barrel by the drill contractor under thesupervision of Andina Copper personnel and placed in core boxes withappropriate depth markers and padding added. Full core boxes were thensealed before being transported by helicopter and pickup truck to theCobrasco core-cutting facility in Quibdó. Core was cleaned, marked-upand photographed, prior to undergoing the required geotechnical andgeological logging. All core was cut by diamond saw by Andina Coppertechnicians, other than the top saprolite intervals that could be cutby spatula. All sampling was conducted in nominal 2m intervals and inall cases, the cut-line was marked by the supervising geologists toensure representative sampling. Samples were placed in plastic bagswith non-repeatable sample tags and bagged in polyweave bags ready fortransport.
The core trays with the remaining half-core are stored at the AndinaCopper facility in Quibdó for ongoing geotechnical (Terraspecspectral analysis, magsus magnetic measurements, density measurementsand follow-up detailed geological logging. From Quibdó core sampleswere sent to the ALS preparation facility in Medellin, an accreditedlaboratory which is independent of the Company. Prepared sample pulpswere then sent to the ALS laboratory in Lima, Peru for gold (Au-AA23),multi-elements (ME-MS61), and overlimits limits analysis (ME-OG62including copper Cu-OG62). Coarse and fine rejects are returned by ALSMedellin for storage at the Andina Copper storage facility.
Mineralized intercepts reported for CDH004 have applied a 0.2% Cucut-off and maximum dilution of 20m.
