Collective Mining Outlines Multiple, High-Grade Vein Systems at Olympus with Assay Results

from Channel Sampling of up to 137 g/t Gold and 563 g/t Silver

Toronto, Ontario, June 1, 2022 – Collective Mining Ltd. (TSXV: CNL) (“Collective” or the

“Company”) is pleased to announce high-grade gold and silver channel sample assay results from its

grassroots generated Olympus target (“Olympus”) located within the Guayabales project

(“Guayabales”), Colombia. Olympus is centrally situated within the four-by-four kilometre porphyry

cluster where to date, the Company has generated eight drill targets through grassroots prospecting.

Four of these targets have been drill tested yielding three significant discoveries including the Olympus

target where the Company recently announced near surface discovery holes of 302 metres @

1.11 g/t gold equivalent and 216.7 metres @ 1.08 g/t gold equivalent (refer to press release dated

March 15, 2022 and May 9, 2022, respectively). As part of its fully funded 20,000+ metre program for

2022, Collective presently has three diamond drill rigs operatin g at Guayabales with drills turning at

the Trap and Apollo targets and a fourth rig expected to kick off a phase II drilling program at Olympus

at the beginning of Q3, 2022.

Highlights (Table 1 and Figures 1, 2 and 3)

x Assay results of chip channel samples taken from veins located within historical, shallow

underground workings from Olympus continue to confirm the prese nce of a high-grade

carbonate base metal (“CBM”) sheeted vein system into the south west portion of the target

area with results as follows:

*Channel chip samples reported above are over true horizontal sampling widths of between 0.1 and 1 metre. Sample grades are unca pped. Channel samples are

representative of 2-dimensional space and as a result should not be relied upon as being representative of average grades anticipated in any future resource estimate

or mining scenario. Assay results for base metals are still pending for all samples listed.

x Multiple CBM veins were sampled at Olympus, over an area measuring 250 metres x 250

metres from limited and partial exposures of rock in old tunnels. The CBM veins are sulphide

rich and associated with intense sericite alteration superimpos ed on porphyry diorite and

mineralized, hydrothermal breccia. Porphyry-related CBM veins c an demonstrate robust

continuity over significant vertical and lateral dimensions and the Company will assess through

drilling whether those characteristics apply to the Olympus vein system.

x Drilling, underground sampling and surface mapping to date hav e expanded Olympus to a

target area measuring more than 1,400 metres by 900 metres, whi ch hosts over 50

artisanal mines with over 25 veins mapped from available exposures. The Company

believes that the probability is high that additional veins wil l be discovered as exploration

ramps up. The Olympus target is open to the east, west, northwest, south and at depth.

x Olympus now includes two mineralized zones. Both zones contain multiple porphyry and

overprinting CBM veins associated with intense pyrite-sericite-carbonate alteration and hosted

in a porphyry diorite (Eastern zone) and within schist country rocks intruded by porphyritic

diorite (Western zone).

x The highest-grade samples collected to date at Olympus come from areas that have yet

to be drill tested by the Company. Diamond drilling completed to date has only focused on

a small northern portion of the Eastern and Western zones while recent surface and

underground mapping has expanded the Western zone to the west and southwest.

x The Company reconfirms that it is on track with construction of underground drill

chambers with the first rig anticipated to commence drilling in July 2022 followed by a

second rig shortly thereafter.

Technical Information

Rock samples have been prepared and analyzed at SGS laboratory facilities in Medellin, Colombia

and Lima, Peru. Blanks, duplicates, and certified reference sta ndards are inserted into the sample

stream to monitor laboratory performance. Crush rejects and pul ps are kept and stored in a secured

storage facility for future assay verification. No capping has been applied to sample composites. The

Company utilizes a rigorous, industry-standard QA/QC program.

About Collective Mining Ltd.

Collective Mining is an exploration and development company foc used on identifying and exploring

prospective mineral projects in South America. Founded by the t eam that developed and sold

Continental Gold Inc. to Zijin Mining for approximately $2 billion in enterprise value, the mission of the

Company is to repeat its past success in Colombia by making a significant new mineral discovery and

advancing the projection to production. Management, insiders an d close family and friends own

approximately 40% of the outstanding shares of the Company and as a result, are fully aligned with

shareholders. Collective currently holds an option to earn up to a 100% interest in two projects located

in Colombia. As a result of an aggressive exploration program at both the Guayabales and San Antonio

projects a total of eleven major targets have been defined. The Company is fortuitous to have made

significant grassroots discoveries on both projects with discovery holes of 302 metres @ 1.1 g/t AuEq

and 163 metres @ 1.3 g/t AuEq at the Guayabales project and 710 metres @ 0.53 AuEq at the San

Antonio project. (See press releases dated October 18th and 27th, 2021 and March 15, 2022, for AuEq

calculations.)
