Andina Copper Reports 232m at 0.68% Cu, 75ppm Mo from 38m
(TSX-V:ANDC) (FSE:FIR) (OTCQB:PMMCF) For Immediate Release
April 14, 2026 – Vancouver, British Columbia.
Andina Copper Corporation (TSX -V: ANDC | FSE: FIR | OTCQB: PMMCF) is pleased to report
another outstanding drill intercept from hole CDH006, the first hole from a new step-out drill pad
at the Cobrasco Project in Chocó, Colombia.
Following the high-grade Cu-Mo intersections reported in recent drillholes CDH003 to CDH005,
drillhole CDH006 was collared on a step-out platform located approximately 400m northwest of
the previous drill pads. The hole was designed to test the northwest extension of the
mineralized system and is the first of several holes planned from this location.
Assay results from CDH006 are highly encouraging, with near -surface mineralization
commencing at 38m within weathered saprolite and continuing through multiple anomalous
intervals in rhyodacitic porphyries to a faulted contact at 808m. Two additional holes have since
been completed from the same drill platform in rapid succession. Visible mineralization has been
observed in both holes, and assay results are pending.
HIGHLIGHTS:
• CDH006 confirms the continuity of the Cobrasco Central Cu-Mo mineralization system to
the NW.
486m @ 0.42% Cu, 51ppm Mo, 1.20g/t Ag
Including 336m @ 0.51% Cu, 53ppm Mo, 1.50g/t Ag
Including 232m @ 0.68% Cu, 75ppm Mo, 2.0g/t Ag from 38m
• Additional step-out drillholes CDH007 and CDH008 have been completed from same drill
platform testing extensions to mineralization in NE and N orientations (assays pending).
• Ongoing program of drilling has added to the known mineralization footprint at Cobrasco
Central, with every drillhole completed to date returning significant porphyry Cu -Mo
mineralization from surface or near-surface to depths of approximately 600m.
• Systematic step-out drilling continues to expand the known mineralization footprint within
the upper 600m , already covering a lateral extent of approximately 950 x 525m , which
remains open in all directions.
• Significant porphyry complex, comprising multiple intrusive phases, subvolcanic flow -
domes and mineralization events demonstrated at Cobrasco Central . The mineralized
system currently remains open in all directions and will continue to be targeted in Andina’s
ongoing drill program.

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 525m within the emerging Cobrasco Central mineralization.
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. A new program of
surface mapping and geochemical sampling is being prepared to run concurrently with this
drilling and is intended to delineate multiple targets for follow-up sampling and drilling.
Preparations are also underway for the mobilization of a second drill rig, which will support both
the definition of new mineralized targets and in-fill drilling across the widely spaced scout holes
completed to date”.

Geology and Mineralization - Drillhole CDH006
Previous drillhole CDH005 was planned as a large step-out to the south, testing the extension of
the Cobrasco Central mineralized footprint towards the southern limits of the concession
boundary. This drillhole was notable for wide intervals of moderate-grade mineralization in a new
intermediate porphyry unit of daci -andesitic composition (r efer Table 1: Cobrasco Project -
Significant Drill Intercepts ). The discovery of large intercepts of Cu -Mo mineralization in this
distinct magnetic host unit has opened b road areas for ongoing surface and down -hole
exploration in the southern portions of the Cobrasco concession (refer to Figure 1).

Drillhole CDH006 was collared approximately 400m NW of the previous drill pad #4 (CDH002 –
CDH005) and approximately 300m SW of pad #1 (CDH001). This new location (pad #3) will be
used to drill a fan of holes testing the overall NW-extension of the mineralization footprint.
Hole CDH006 (Az: 225 o Dip: -60º Depth: 898.90m), being the first hole from this drill pad was
collared to test a SW section, parallel to holes CDH001 and CDH004, covering approximately
500m in the horizontal and 750m in the vertical planes. In broad terms, the lithologies intersected
in CDH006 correspond to felsic porphyries of rhyodacite composition with mineralized intervals
related to chalcopyrite sometimes replaced by bornite in intensely fractured rocks.
Hydrothermal alteration is strong argillic in the upper portions of the drillhole, progressing to phyllic
and ubiquitous grey -green-sericite (GGS) which has been associated with the bulk of the
mineralization defined thus far.

The importance of structural controls to the observed mineralization is more evident in drillhole
CDH006 than in the previous holes. Here we can see a clear association between the structural
preparation of the host units (shearing and brecciation - related permeability) and the resulting
degrees of alteration and mineralization.
In general terms, the upper ~46m of the drill core are strongly weathered and characterized by
saprolites with strong oxidation and clay formation. A low-angle fault-structure (sub-parallel to drill
axis) at this point marks the introduction of high copper and molybdenum grades (e.g. sample
G517536: 46 – 48m 4.6% Cu, 1495ppm Mo). The rocks bounding this structure are friable, with
strong argillic alteration, with mineralization being predominantly pyrite-chalcopyrite with traces of
bornite. At greater depth s, lithology is characterized by more competent units of rhyolite and
rhyodacite with local occurrences of quartz -sulphide veining. Alteration is typically weak to
moderate GGS increasing to phyllic alteration particularly over zones of brecciation. A well -

marked zone of magmatic brecciation in the felsic porphyry units extends to 270m, typically
characterized by an increase in A -veins and high Cu -Mo grades. Th e interval 38m to 270m
contains the stand-out mineralized intercept reported in this announcement (232m at 0.68% Cu,
75ppm Mo from 38m).
Refer to Figure 3 which describes characteristic examples of host lithologies, alteration and
mineralization in the upper 270m of drillhole CDH006.

mineralized interval.
A faulted contact at 808m marks the end of the magmatic-hydrothermal brecciation in the drillhole
and the start of a distinct polymictic intrusive breccia showing matrix -supported sub-angular to
sub-rounded rhyolite to microdiorite fragments in a pyritic matrix. Mineralization decreases

markedly although sporadic mineralized intervals continue to the end of hole (e.g. Sample
G543022: 894 – 896m 0.48% Cu, 58ppm Mo).
Refer to Figure 4 which describes a selection of characteristic samples from the deeper (> 270m)
sections of drillhole CDH006.

CDH006 was collared with a PQ size drill string to a depth of 138m, continued with HQ/HQ3 to
678.10m and completed to a final depth of 898.90m with NQ/NQ3 diameter rods. In all cases the
drill core was 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 (core blocks) and
padding added for extra protection during transport. 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 where required , marked -up and photographed, prior to undergoing
geotechnical and geological logging. All core was cut by diamond saw by Andina Copper
technicians, other than the top saprolite intervals that could be cut and sampled by hand tools. All
sampling was conducted in nominal 2m intervals with cut -lines marked by the supervising
geologists to ensure representative sampling. Samples were placed in plastic bags with non -
repeatable sample tags and bagged in polyweave sacks 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, magnetic susceptibility readings, rock 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” analysis (ME-OG62 including copper Cu-
OG62). Coarse and fine rejects are returned by ALS Medellin for storage at the Andina Copper
storage facility.
