Step Out Drilling Materially Expands the Overall Dimensions of

Collective Mining’s Main Breccia Discovery at Apollo

• Visual observations from two step-out diamond drill holes within the Company’s Main

Breccia discovery at the Apollo target have intersected the most cumulative

mineralization in drill hole s completed to date a s well as significantly expanded the

known dimensions of this exciting new discovery.

• Hole APC-17, which was drilled due north from Pad 3, cut more than 600 metres in total

of favourable mineralization before terminating at approximately 913 metres while still

in mineralization. This is the most mineralization encountered in a drill hole to date at

the Apollo target.

• Hole APC-22, which was drilled to the northeast from Pad 3, cut more than 400 metres

in total of favourable mineralization before terminating at 734 metres while still in

mineralization.

• As a result of both new holes, the potential total volume of rock hosting the Main

Breccia discovery within it has approximately tripled in size with the dimensions now

measuring 385 metres along strike by 350 metres width by 825 metres depth versus

prior dimensions of 385 metres x 190 metres x 500 metres. The discovery remains wide

open for expansion and further step-out holes are currently being designed.

• Three rigs continue to drill at Apollo with additional assay results anticipated in the near

term.

Toronto, Ontario, October 11, 2022 – Collective Mining Ltd. (TSXV: CNL) (OTCQX: CNLMF)

(“Collective” or the “Company”) is pleased to announce visual observations from two step out holes

drilled into the Apollo target (“Apollo”) which is located within the Guayabales project in Caldas,

Colombia. The Main Breccia discovery at Apollo is a high -grade, bulk tonnage copper -gold-silver

porphyry-related breccia target with previously announced intercepts including:

Hole Intercept (m) Au (g/t) Ag (g/t) Cu % Zn % Pb % Mo % AuEq (g/t) *

APC-2 207.15 1.46 45 0.31 0.08 0.05 0.002 2.68

APC-8 265.75 1.26 55 0.22 0.07 0.05 0.045 2.44

APC-12 237.70 1.15 72 0.38 0.08 0.07 0.001 2.88

* See press releases dated August 10th, September 13th and October 6th respectively.

As part of its fully funded 20,000+ metre drill program for 2022, there are currently three diamond drill

rigs operating at the Apollo target.

“These two new diamond drill holes are incredibly exciting as we have significantly expanded the size

of the Main Breccia discovery at Apollo and while doing so, we have cut the longest intercepts of both

total and continuous mineralization completed to date. Importantly, the system remains open to the

north and northeast as both holes bottomed in mineralization. We look forward to continued aggressive

drilling in order to see how much more this exceptional discovery can grow,” commented Ari Sussman,

Executive Chairman.

Details (See Figures 1–4)

Fourteen diamond drill holes with accompanying assay results have now been announced at Apollo

and a further eleven holes are outstanding. The Company recently completed two northerly directed

diamond drill holes, APC-17 and APC-22, from its southernmost drill pad (Pad 3), which were designed

to test for mineralized extensions to the Main Breccia discovery. The following visual observations are

highlighted from the two step out holes:

• Hole APC-17 was drilled approximately due north to a maximum depth of 912.60 metres. The

hole intersected more than 70 metres of mineralization beginning at 119 metres down hole

(100m vertical) and another 545 metres of mineralization from 365 metres down hole (330m

vertical) to the end of the hole (825m vertical). Total mineralization in this diamond drill

hole exceeded 600 metres and is the most mineralization drilled in a single hole to date

into the Main Breccia discovery at Apollo. The shallow intercept is hosted within angular

porphyry related breccia containing chalcopyrite (1-2%) with pyrite and pyrrhotite and is

located directly beneath recently discovered mineralization outcropping at surface. The deeper

and longer intercept is also hosted within angular porphyry related breccia with the matrix filled

with pyrite, chalcopyrite and overprinting carbonate base metal veins (“CBM”). The hole was

terminated at 912.6 metres while still in mineralized breccia.

• Hole APC -22 was drilled to the n ortheast to a maximum depth of 734.8 metres and

intercepted three zones yielding more than 400 metres of total breccia mineralization.

The two shallow zones are located directly beneath surface outcrops and the initial 37 metre

intercept commenced at 100 metres downhole (60m vertical), while the second shallow 19

metre intercept began at 167 metres down hole (100m vertical). Mineralization is hosted within

angular porphyry breccia with a matrix of chalcopyrite (1-2%) and pyrrhotite and overprinting

zones of sheeted CBM veins. The deeper intercept commenced at 308 metres downhole

(276m vertical) and continued within mineralized porphyry related angular breccia until the

hole was terminated at 734.8 metres.

• Visual logging of APC-17 and APC-22 have significantly increased the overall maximum

potential volume of rock hosting the Main Breccia discovery, which now measures up

to 385 metres along strike by 350 metres width by 825 metres depth (prior dimensions

were 385 metres x 190 metres x 500 metres). The system remains open for expansion.

• Three rigs continue to drill at Apollo with additional assay results anticipated in the near term.

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

molybdenum soil geochemistry, covers an 800 metres X 700 metres area. The Apollo target

area hosts the Company’s new Main Breccia discovery plus a vein system flanking its

eastern side. Multiple additional untested breccia, porphyry and vein targets have been

generated and will be drilled in due course. Lastly, the overall Apollo target area also remains

open for further expansion.
