Collective Mining Expands Apollo to the Southwest and at Depth by

Intersecting 389.45 Metres at 1.36 g/t Gold Equivalent up to 935 Metres

Below Surface

o Four directional holes drilled into the Apollo Porphyry System (“Apollo”) have expanded the

wireframed envelope to the southwest , intercepted high -grade mineralization at the deepest

vertical depth drilled to date and improved upon the grade profile below 1,500 metres elevation

in a sparsely drilled area.

o APC70-D4 intersected 389.45 metres @ 1.36 g/t gold equivalent up to 9 35 metres below

surface with the final 21.8 metres of this intercept grad ing 4.41 g/t gold equivalent . APC70-

D4 has locally extended the system by 100 metres to the southwest and intercepted the

deepest mineralization ever encountered at Apollo.

o APC70-D1, which was drilled to the south across the Apollo system at a near true angle,

intersected 199.40 metres @ 1.65 g/t gold equivalent , including 26.5 metres @ 3.48 g/t gold

equivalent to a max imum vertical depth of 745 metres below surface .

o APC70-D2, which was drilled to the southeast also at a near true angle to the Apollo system,

intersected 168.20 metres @ 1.32 g/t gold equivalent , including 21.35 metres @ 3.11 g/t gold

equivalent to a maximum vertical depth of 625 metres below surface .

o APC70-D3, which was drilled to the southwest, intersected 168.80 metres @ 1.82 g/t gold

equivalent to a maximum vertical depth of 654 m etres below surface. The hole bottomed

while still in mineralization with the final 4.7 0 metres grading 1.4 0 g/t gold equivalent

indicating potential for further expansion of the mineralized envelope .

o Visual logging of recently completed directional drill hole APC70 -D5 and APC88 -D1 have

intercepted a potential expansion at depth for Apollo as well as a new porphyry unit located

north of Apollo under the Olympus system. Assay results for both holes are expected in

January.

o Drilling continues at the Guayabales project with four rigs, two operating at the Apollo and

Trap targets respectively and a backlog of assay results expected in the near future.

Ari Sussman, Executive Chairman commente d: “Our directional drill program is off to an excellent

start by demonstrating that orthogonal drilling improves the grade profile locally due to an

abundance of zones flooded with mineralized CBM vein fluid . Additionally , directional drilling is

making it much easier for the Company to test and expand the Apollo envelope by allowing the

Company to quickly reach areas that are not possible to drill from surface due to topography. V isual

observations of holes APC70-D5 (Pad 1) and APC88- D1 (Pad 14) notes intercepts of more than

500 metres (APC70-D5) and 500 metres plus a second zone of more than 200 metres (APC -88-

D1) indicating that a potential material size increase to the envelope of the system will be

forthcoming upon receipt of assays in early Q1, 2024 .”

Toronto, Ontario, December 11 , 2023 - Collective Mining Ltd. (TSX: CNL, OTCQX:

CNLMF) (“Collective” or the “Company”) is pleased to announce a ssay results from the first

four directional drill holes into the Apollo porphyry system (“Apollo ”). Apollo hosts an outcropping

high-grade, bulk tonnage gold -silver- copper-tungsten porphyry system measuring 520 metres x

395 metres x 935 metres (previously 915 metres) which remains o pen for further expansion.

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 and Figures 1-5)

This press release outlines the first results from the mother hole (APC-70) and four directional holes

(APC70-D1 to D4) drilled from the end of the mother hole and designed to test for grade continuity at

depth as well as western extensions to the Apollo porphyry system. APC-70 was drilled due south

from Pad 1 and its directional holes form a fan pattern from southeast to southwest , intersecting the

Apollo system more perpendicularly than prior drilling.

APC-70 was the mother hole for this first directional program and was drilled steeply to the south from

Pad 1 to a final downhole depth of 293.30 metres. The principal objective of this hole was to reach the

optimal depth to commence the directional drillholes . T he hole intersected shallow minerali zation

related to carbonate and base metal (“CBM”) veining at 83.30 metres downhole for 22.70 metres with

assays results as follows:

• 22.70 metres @ 1.18 g/t gold equivalent from 83.30 metres downhole.

APC70-D1 was the first deflection from the mother hole and was drilled due south to a final directional

downhole depth of 624.10 metres (745 metres vertical from surface due to depth of mother hole). The

hole entered brecciated porphyry at 229.30 metres downhole and continued in minerali zation for

199.40 metres . The minerali zed breccia zone consists of a sulphide matrix cement hosting

chalcopyrite (up to 0.4%), pyrite (up to 1.6%) and pyrrhotite (up to 0.8%) as well as later and

overprinting CBM vein sulphides such as sphalerite (up to 0.8%), galena (up to 0.3%) and trace

amounts of fine, free gold with assay results as follows:

• 199.40 metres @ 1.65 g/t gold equivalent from 229.30 metres downhole (consisting of

1.46 g/t gold, 11 g/t silver and 0.04% copper) including:

o 32.90 metres @ 2.32 g/t gold equivalent from 281.40 metres downhole and;

o 26.50 metres @ 3.48 g/t gold equivalent from 402.20 metres downhole.

APC70-D1 encountered better grades than previously modelled in this area from drill holes APC-17

and APC-49 and as a result will improve the grade block model in this location. Directional drilling

perpendicular to the breccia body has also identified multiple zones of sheeted CBM veins which were

intersected from downhole depths of 229.30 metres, 281.40 metres and 402.2 metres over intersection

lengths ranging from 22.3 metres to 32.90 metres with grades between 2.32 g/t gold equivalent to 3.48

g/t gold equivalent.

APC70-D2 was drilled in a southeast direction from the mother hole to a maximum downhole deflection

depth of 501.80 metres (625 metres vertical from surface due to depth of mother hole) . The hole

encountered sheeted CBM vein zones at 15.00 metres and 181.40 metres downhole depths fo r

intervals of 11.70 metres and 5.90 metres, with grades of 1.52 g/t gold equivalent and 1.78 g/t gold

equivalent, respectively. The hole entered brecciated porphyry at 213.10 metres depth and intersected

168.20 metres of mineralization consisting of a sulphide cement matrix hosting chalcopyrite (up to

0.3%), pyrite (up to 1.5%) and pyrrhotite (up to 1.0%) with CBM vein sulphides such as sphalerite (up

to 0.3%) and galena (up to 0.2%). The following assay results are highlighted:

• 11.70 metres @ 1.52 g/t gold equivalent from 15.00 metres downhole (consisting of 1.38

g/t gold, 10 g/t silver and 0.02% copper) and;

• 168.20 metres @ 1.32 g/t gold equivalent from 213.10 metres downhole (consisting of

1.14 g/t gold, 11 g/t silver and 0.03% copper) including:

o 21.35 metres @ 3.11 g/t gold equivalent from 240.00 metres downhole.

APC70-D2 also encountered better grades than previously modelled in this area due to the presence

of multiple zones hosting sheeted CBM veins (see Table 1) and as a result will improve upon the grade

block model in this location.

APC70-D3 was drilled southwest to a maximum directional depth of 481.10 metres (654 metres

vertical from surface due depth of mother hole) . At the beginning of the hole, sheeted CBM vein

mineralization was intersected over intervals between 5.10 metres and 28.45 metres with grade s of

up to 3.33 g/t gold equivalent. Beginning at 245 metres downhole, brecciated porphyry mineralization

was intercepted over a total of 168.80 metres. The sulphide mineralization in the breccia matrix in this

interval consists of chalcopyrite (up to 0.3%), pyrite (up to 1.1%), sphalerite (up to 0.6%), galena (up

to 0.8%) and pyrrhotite (up to 1.5%). The following assay results are highlighted:

• 168.80 metres @ 1.82 g/t gold equivalent from 245.50 metres downhole

(consisting of 1.59 g/t gold, 14 g/t silver and 0.03% copper) including:

o 21.65 metres @ 2.27 g/t gold equivalent from 247.95 metres downhole and;

o 108.80 metres @ 2.21 g/t gold equivalent from 305.50 metres downhole.

The APC70-D3 intercept has extended the Apollo system locally for a further 25 metres to the

southwest into an area with no previous drilling. Furthermore, the hole bottomed in

mineralization with the final 4.7 metres grading 1.4 g/t gold equivalent, opening the opportunity

for further mineralization extensions in this area.

APC70-D4 was drilled southwest to a maximum directional downhole depth of 728.25 metres (9 35

metres vertical from surface due to depth of mother hole). APC70-D4 is the deepest hole drilled to

date at Apollo, reaching depths of 935 metres below surface (1,075 RL).

From 45.25 metres to 197.80 meters the hole encountered a series of sheeted CBM vein intervals

hosted within quartz diorite porphyry . Beginning at 268.55 metres downhole, the hole intersected

389.45 metres of brecciated porphyry mineralization with sulphide matrix cement hosting chalcopyrite

(up to 0.2%), pyrite (up to 3.0%), sphalerite (up to 0.5%), galena (up to 0.2%) and pyrrhotite (up to

1.3%). The following assay results are highlighted:

• 4.25 metres @ 14.35 g/t gold equivalent from 119.35 metres downhole (consisting of

13.87 g/t gold, 60 g/t silver and 0.02% copper) and;

• 389.45 metres @ 1.36 g/t gold equivalent from 268.55 metres downhole (consisting of

1.17 g/t gold, 11 g/t silver and 0.03% copper) including:

o 84.25 metres @ 1.88 g/t gold equivalent from 456.25 metres downhole and;

o 21.80 metres @ 4.41 g/t gold equivalent from 636.20 metres downhole.

The results of directional hole APC70-D4 confirm the discovery of a 100-metre southwest depth

extension to the Apollo Porphyry system . Apollo remains open to the west for further

expansion and recent visual logging of new, westerly directed, directional hole APC70-D5 has

confirmed the discovery of over 500 metres of brecciated porphyry mineralization in this area.

Exploration Drill Program and Assay Update

Diamond drilling at the Guayabales project currently totals 128 drill holes (approximately 51,3 80

meters) completed and assayed. The 2023 Phase II drilling program is advancing on schedule with

assay results reported for 57 holes and an additional ten holes awaiting assay results from the

laboratory.

With f our diamond drill rigs now operating at site, the Company is advancing with the following

objectives:

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 to

the north, west and at depth.

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 (see press release dated September 7,

2022) and containing similar mineralization to the Apollo porphyry system. Follow up drilling is

now underway and initial assay results are expected in due course.

The Apollo area, as defined to date by surface mapping, rock sampling and copper and molybdenum

soil geochemistry covers a 1,000 metres X 1,200 metres area and represents a large and unusually

high-grade gold- silver-copper tungsten porphyry system. Mineralization styles include early -stage

porphyry veins, inter -mineral brecciated porphyry mineralization and multiple zones of late stage,

sheeted, carbonate -base metal veins with high gold and silver grades. The Apollo area is still

expanding as the Company’s geologists have found multiple additional outcrop areas with porphyry

veining, breccia, and late stage, sheeted, carbonate base metal veins. (See press release dated April

18, 2023)
