Drill Results

Collective Mining Reports a New Precious Metal Discovery at its

Guayabales Project by Drilling 136.45 Metres at 1.31 g/t Gold

Equivalent at the Plutus Target

• Drill hole PNC-2 was drilled in the western portion of the Plutus Northern Corridor

which forms part of the large Plutus porphyry centre. The hole was designed to pass

through the previously drilled Donut breccia (now part of the Plutus North Corridor)

in order to drill test below a newly discovered mineralized breccia outcrop.

• PNC-2 cut three mineralized intervals with the first and third intersecting new zones

of mineralization. Importantly, the third zone intersected 136.45 metres @ 1.31 g/t

gold equivalent in a new porphyry related breccia discovery with an abundance of

CBM vein sulphides flooding the matrix. The hole was terminated prematurely in an

area of complicated faulting.

• The geochemical signature of the mineralization encountered in PNC-2 i s

interpreted to be at the edge of a major new porphyry system in the Plutus target

area.

• Mineralization defined to date in the Plutus Northern Corridor measures 285 metres

in strike by 250 metres width by 375 metres vertical and remains open to the east,

south, southwest and at depth.

• Five drills are currently in operation at the Guayabales project with three rigs drilling

at the Apollo porphyry system, one rig drilling at the Plutus target and the final rig

drilling initial reconnaissance holes at the Marmato Extension target (“ME target”).

Additionally, drilling is expected to begin in Q4 2023 at the Trap target, which

displays similar mineralization styles as the Apollo porphyry system. Fourteen new

diamond drill holes have recently been completed with assays pending in the near

term.

Ari Sussman, Executive Chairman commented: “Making a new discovery in only the second hole

drilled in the Plutus Northern Corridor as part of the 2023 exploration program is a testament to

both the tenacity of our operating team on the ground and the robust geology of the intrusion

complex at the Gu ayabales project . We remain steadfast in our goal of being aggressive with

drilling to unlock as much value as we can in what we firmly believe is an emerging mining district .

The area in which we operate has all the earmarks of evolving into a series of important and

strategic deposits for Colombia and we are honored to help push this initiative forward for our

stakeholders and shareholders. ”

Toronto, Ontario, October 11 , 2023 - Collective Mining Ltd. (TSX: CNL, OTCQX: CNLMF)

(“Collective” or the “Company”) is pleased to announce assay results for two diamond holes drilled

into the Plutus Northern Corridor, which is one of a series of targets at the Guayabales Project located

in Caldas, Colombia. The Plutus Northern Corridor forms part of the la rger Plutus porphyry centre

(“Plutus”) and is located approximately 1,000 metres east of the Apollo porphyry system.

Plutus measures approximately 1,000 metres by 720 metres as outlined by a magnetic high which is

coincident with copper and molybdenum soil anomalies measuring greater than 300 ppm and 20 ppm

respectively. The Plutus Northern Corridor, situated within the northern portion of Plutus, hosts

brecciated porphyry and overprinting CBM vein mineralization within a NE-SW trending corridor. The

Plutus Northern Corridor target zone is coincident with the transitional area between a magnetic high

and a magnetic low as seen in magnetic susceptibility sections. It is worth noting that the Apollo

porphyry system, as well as the area currently being dr illed for the first time by the Company at the

ME target, are also located in the same magnetic transition zone.

Details (See Table 1 and Figures 1-3)

This press release outlines results from two holes designed to test below new recently defined

outcropping targets within the Plutus Northern Corridor.

PNC-2 was drilled southwest from a new pad, PPad 1, to a maximum downhole depth of 579.40

metres (450 meters vertical due to topography). The hole entered a 35.10 metre mineralized zone at

65.30 metres downhole and is hosted in diorite and quartz diorite porphyry rocks with multiple quartz,

magnetite, chalcopyrite, and molybdenum veinlets (up to 2% veinlet density) being observed. At a

downhole depth of 143.20 metres, the hole intercepted a continuous zone of hydrothermal breccia for

185.80 metres with the cement matrix hosting 0.1% chalcopyrite, 1% pyrite, 0.2% sphalerite, and 0.1%

pyrrhotite. At 369.35 metres downhole, the hole entered a new zone of mineralization located below a

recently identified outcrop and cut 136.45 metres of continuous hydrothermal breccia with overprinting

CBM veinlets. This new mineralized zone hosts a sulphide cement matrix of chalcopyrite (up to 0.3%),

pyrite (up to 1.5%), sphalerite (up to 0.6%), galena (up to 0.5%) and pyrrhotite (up to 0.7%) with assay

results as follows:

• 35.10 metres @ 0.41 g/t gold equivalent from 65.30 metres downhole (consisting of 0.20

g/t gold, 2 g/t silver and 0.10% copper) in mineralized porphyry;

• 185.80 metres @ 0.81 g/t gold equivalent from 143.20 metres downhole (consisting of

0.59 g/t gold, 13 g/t silver and 0.02% copper) in hydrothermal breccia, and;

• 136.45 metres @ 1.31 g/t gold equivalent from 369.35 metres downhole (consisting of

0.97 g/t gold, 20 g/t silver and 0.04% copper) in hydrothermal breccia including:

o 42.95 metres @ 2.39 g/t gold equivalent from 462.35 metres downhole in breccia

with overprinting sheeted CBM veinlets.

PNC-1 was drilled south-southwest from PPad 1 to a maximum downhole depth of 594.95 metres (490

meters vertical due to topography) and encountered diorites and quartz diorite porphyry rocks with

secondary biotite alteration and veinlets of quartz, magnetite, chalcopyrite, and molybdenum with

assay results as follows:

• 22.45 metres @ 0.32 g/t gold equivalent from surface (consisting of 0.19 g/t gold, 1 g/t

silver and 0.04% copper);

• 85.05 metres @ 0.31 g/t gold equivalent from 53.00 metres downhole (consisting of 0.18

g/t gold, 1 g/t silver and 0.06% copper);

• 39.35 metres @ 0.35 g/t gold equivalent from 169.75 metres downhole (consisting of

0.11 g/t gold, 4 g/t silver and 0.09% copper);

• 24.40 metres @ 0. 35 g/t gold equivalent from 254.90 metres downhole (consisting of

0.11 g/t gold, 5 g/t silver and 0.07% copper) and;

• 31.35 metres @ 0.5 3 g/t gold equivalent from 312.10 metres downhole (consisting of

0.25 g/t gold, 6 g/t silver and 0.09% copper).

Based on drilling, the known mineralized dimensions of the Plutus Northern Corridor measures 285

metres in strike by 250 metres width by 375 metres vertical and remains open in most directions for

expansion.

Exploration Drill Program and Assay Update

The 2023 Phase II drilling program is advancing on schedule with assay results reported for 41 holes

and an additional 14 holes awaiting assay results from the lab.

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

objectives:

1. E xpanding the Apollo porphyry system both laterally and vertically. The Company is currently

advancing with directional drilling for the first time with the initial fan of four holes now complete.

Additionally, the Company is drilling a series of short holes from surface targeting extensions

to the sheeted CBM vein systems located above and peripheral to the Apollo brecciated

porphyry. Three drill rigs are actively drilling at Apollo.

2. Drill test the Marmato Extension (“ME”) porphyry centre for the first time in search of both a

high-grade sheeted CBM vein system at shallow elevations and a potential buried porphyry

system at depth. One drill rig is currently active at ME.

3. 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 mineralization to

the Apollo porphyry system.

4. Fly airborne geophysics on the Plutus target ahead of first phase drilling of the large and

untested coincidental copper and molybdenum in soil anomaly covering the central and

southern portion of the target area.

metal prices of Cu – US$3.85/lb, Ag – $24/oz Mo - US$25/lb and Au – US$1,475/oz and recovery rates of 97% for Au, 88% for Ag,

85% for Mo, and 90% for Cu. Recovery rate assumptions are speculative as limited metallurgical work has been completed to date.

True widths are unknown, and grades are uncut.
