Collective Mining Exploration Update: Trap Drilling Underway and Short
Hole Drill Program at Apollo Delivers High-Grade Intercepts
o Drilling is now underway at the Guayabales Project’s Trap porphyry target (“Trap”) with the
objective of following up on the 2022 discovery hole TRC -1, which intersected 102.20
metres of gold- silver-copper mineralization averaging @ 1.53 g/t gold equivalent.
o Trap is located approximately three kilometres to the northeast of the Company’s flagship
Apollo porphyry system (“Apollo”) and is significantly larger than Apollo in dimensions
measuring approximately 2 kilometres by 2 kilometres in area .
o The mineralization styles and geochemical signatures encountered at Trap are very similar
to those observed at the Apollo system, namely porphyry vein and alteration systems being
overprinted by subsequent carbonate base metal (“CBM”) sheeted vein systems.
o High-grade assay results have been received from a short hole drill program at Apollo. The
aim of the program was designed to provide important data for block modelling by infilling
the shallowest portion of the dip of the system as it moves under cover , with results
including :
o 130.45 metres @ 2.17 g/t gold equivalent from 119.90 metres downhole in APC-80.
o 98.75 metres @ 2.71 g/t gold equivalent from 132.35 metres downhole in APC-82.
o Drilling in the south ern part of Apollo into the porphyry halo located outside of the high -
grade brecciated porphyry system has cut shallow, lower grade mineralization while
extending the maximum known dimensions of the brecciated porphyry to 560 metres
(previously 520 metres) . The system remains open to the west, north and at depth . Assay
results includ e:
o 109.15 metres @ 0.46 g/t gold equivalent from 7 metres downhole in APC -75.
o Drilling continues at the Guayabales project with four rigs currently in operation and a
backlog of assay results expected in short order . Assay r esults outstanding include a
series of direction al drill holes at Apollo as well as initial results from the ME target area.
Ari Sussman, Executive Chairman commente d: “Trap is an extremely exciting target, one which
we did not appreciate appropriately when the discovery hole was drilled in mid -2022 as our
geological knowledge of the Guayabales project was only in its infancy . After careful review , it is
now clear that t he 2022 Trap discovery hole is hosted in a long and continuous zone of quartz
diorite porphyry with overprinting styles of mineralization similar to those observed at Apollo. Trap
possesses all the characteristics of a potentially large porphyry system, and we look forward to
seeing what transpires from our drilling program now underway.”
Toronto, Ontario, November 22, 2023 - Collective Mining Ltd. (TSX: CNL, OTCQX:
CNLMF) (“Collective” or the “Company”) is pleased to announce t hat is has commenced drilling
at the Trap target (“Trap”) and assay results for seven holes drilled in the Apollo porphyry system
(“Apollo ). Apollo and Trap are both targets within t he Company’s flagship Guayabales project
located in Caldas, Colombia. Presently, there are four diamond drill rigs operating at the
Guayabales project as part of the Company’s planned 42,000 metre drilling program for 2023.
Details (See Table 1-4 and Figures 1-2)
This press release outlines details of the Trap target and results from seven holes drilled within and
peripheral to the Apollo system.
Trap Target
The Company announces that drilling is now underway at the Trap target in the northern portion of the
Guayabales project. Trap is located approximately three kilometres to the northeast of the Apollo
Porphyry system in the largest porphyry intrusion centre outlined to date at the Guayabales project.
On September 27, 2022, grass roots reconnaissance drilling at Trap resulted in a porphyry discovery
with drill hole TRC-1 assaying 102.20 metres @ 1.53 g/t gold equivalent (Table 1) including:
• 16.10 metres @ 2.63 g/t gold equivalent from 250.20 metres downhole related to a copper-
gold-silver porphyry style mineralization (Table 2).
• 14.70 metres @ 2.00 g/t gold equivalent from 289.00 metres downhole related to gold-
silver rich CBM style mineralization (Table 3).
Mineralization styles and metal geochemistry at Trap is very similar to the Apollo porphyry system in
terms of gold, silver, and copper (see Tables 2 and Table 3). Hole TRC-1 intersected porphyry style
mineralization (see Table 2, downhole depths from 250.2 metres to 26 6.30 metres) with secondary
biotite, hydrothermal magnetite (up to 0.5%) in veinlets, albite, chlorite, chalcopyrite (up to 1.0 % and
replacing the magnetite) and pyrite (up to 1.3%). Below this at 289.00 metres downhole, the hole
entered into a polymetallic, CBM mineralization phase enveloped by strong sericite alteration. The
sheeted carbonate veins host gold, silver, lead and zinc with sulphides including sphalerite (up to
0.5%), galena (up to 0.2%), pyrite (up to 2.0%), copper oxides, quartz, and carbonates.

Apollo Drilling
Three holes were drilled from Pad 12 in order to better outline the shallowest portion of the dip of the
system for block modelling. H igh-grade and shallow brecciated porphyry mineralization w as
intersected in holes APC-80, APC-82 and APC-84 (see Table 4) and was fringed to the north by lower
grade and peripheral mineralization. These three holes have added grade and volume at shallow
levels to the Apollo system with assay results as follows:
o 130.45 metres @ 2.17 g/t gold equivalent from 119.90 metres downhole in APC-80.
o 98.75 metres @ 2.71 g/t gold equivalent from 132.35 metres downhole in APC-82.
o 53.70 metres @ 0.67 g/t gold equivalent from 120.00 metres downhole in APC-84.
Additionally, from Pad 3, drillhole APC-75, APC-77 and APC-79 (see Table 4) were fanned in southerly
directions to test for the potential of the low -grade halo of mineralization surrounding the main
brecciated high-grade Apollo system . These holes were drilled so that the Company can begin to
assess the potential of the low-grade halo and its potential to positively impact future mining scenarios
as well as determining the eastern boundary of the Apollo intrusion. Assay results are as follows:
o 109.15 metres @ 0.46 g/t gold equivalent from 7.00 metres downhole in APC-75.
o 36.10 metres @ 0.36 g/t gold equivalent from 52.40 metres downhole in APC-77.
As a result of drill holes APC -75 and APC-77, the maximum known strike of the Apollo system has
been extended by 40 metres and now measures 560 metres in length.
Finally, a seventh hole, APC-76 was drilled to the west from Pad 5 with the objective of intersecting a
deep zone of the brecciated porphyry. Unfortunately, the hole was abandoned at a shallow depth
before reaching the target zone when it entered a fault zone and encountered mechanical problems.

Exploration Drill Program and Assay Update
Diamond drilling at the Guayabales project now totals 123 drill holes (approximately 48,751 meters)
completed and assayed. The 2023 Phase II drilling program is advancing on schedule with assay
results reported for 52 holes and an additional ten holes awaiting assay results from the lab.
The Company now has four diamond drill rigs operating within the Guayabales project area with the
following objectives for the remainder of 2023:
1. Expanding the Apollo porphyry system both laterally and vertically. The Company is currently
advancing with directional drilling utilizing two rigs aimed at expanding the Apollo system at
depth, to the west and north.
2. Drill test the Trap target in the northern portion on the Guayabales project. Three widely
spaced reconnaissance holes were completed at Trap in 2022 with the discovery hole, TRC-
1 assaying 102.2 metres @ 1.53 g/t gold equivalent and containing similar mineralizatio n to
the Apollo porphyry system. Follow up drilling is now underway and initial assay results are
expected in due course.
