Collective Mining Announces the Initiation of Drilling at the Box Target, a Large and

Mineralized Outcropping Gold-Rich Porphyry System

Toronto, Ontario, October 5, 202 1 – Collective Mining Ltd. (TSX V: CNL) (“Collective” or the

“Company”) is pleased to announce, as part of its 7,500-meter maiden drill program, that it is mobilizing

a second diamond drill rig to the Guayabales Project, Colombia. The new drill rig is expected to begin

operating before the end of October 2021 and will be targeting a grass-root generated large-scale and

mineralized outcropping gold-rich porphyry system within the Bo x target area (“Box”). Box is one of

the five major grass-root drill-ready target areas identified at the Guayabales Project by the Company

in 2021. The Guayabales Project is situated contiguous and imme diately along strike and to the

northwest of Aris Gold’s multi-million-ounce deposit. The Comp any interprets the abundant precious

metal mineralization encountered throughout the Guayabales proj ect to be related to multiple

mineralized styles that include gold-copper-molybdenum porphyries and associated breccia as well

as high grade, precious and base metal vein systems that are su perimposed on and enrich the

porphyry bodies.

Highlights (Table 1 and Figures 1 to 5)

 The porphyry zone (“CPZ”) within the Box is a coincidental str ong gold, silver, copper and

molybdenum soil anomaly characteriz ed by high-grade veins overp rinting porphyry

mineralization. In turn, the mi neralization is situated directl y within coincidental magnetic

chargeability and resistivity geophysical anomalies typical of a porphyry system.

 The surface area for the CPZ at Box measures 500 metres by 400 metres and is open in all

directions for expansion.

 The CPZ has returned channel and grab sampling from three diff erent styles of mineralization;

polymetallic veins, porphyry stockwork and disseminated sulphide. Samples for the high-grade

veins returned a range of intercepts grading up to 14.8 g/t gold and 276 g/t silver. These high-

grade veins are superimposed on porphyry veinlets, stockwork an d disseminated sulphide

mineralized systems with grades ranging from 0.4 g/t to 1 g/t gold with select results as follows:

“The deep penetrating, high resolution IP work when combined with our exploration data has been an

effective targeting tool in defin ing multiple targets consistin g of different mineralization styles at the

Guayabales Project. As a result, the Company is now beginning a robust drill program to test our initial

five targets over the balance of the year and into 2022. Importantly, we expect that initial assay results

from drilling at the Donut target, which commenced in September, will be available prior to the end of

October,” commented Ari Sussman, Executive Chairman.

Details

The CPZ within the Box is in the western portion of the Guayaba les Project and is hosted within

multiple porphyritic diorites which intrude into carbonaceous s chist and siltstone country rocks.

Previously, the Company announc ed channel and rock sample resul ts from small porphyry and

polymetallic vein outcrops within the Box target (see press release dated July 29, 2021). The Company

has now undertaken extensive additional surface work and geophy sical surveys at the Box target

which define a central, mineralized porphyry zone, referred to as the impregnated zone and enveloped

by high grade, polymetallic veins to the north, west and south of the porphyry body (see Figure 1).

The CPZ contains gold mineraliz ed stockwork and sheeted vein sy stems hosting quartz-pyrite-

molybdenite-magnetite-chalcopyrite assemblages that are associa ted with potassic alteration. The

mineralized vein systems are coi ncident with soil anomalies for copper (>500ppm), molybdenum

(>3ppm) and gold (>100 ppb) and cover an area of 500 meters by 400 meters. The mineralized

porphyry system is impregnated by late stage polymetallic veins which host gold, silver, sphalerite,

and galena sulphides. Located to the North and South of the por phyry zone are additional zones of

polymetallic veins which fringe the main porphyry bodies and ar e associated with extensive sericite-

chlorite alteration. The polyme tallic veins locate within inter secting structures and have northeast,

northwest and east-west orientations.

Outcrop exposure within Box is limited due to extensive landslides and colluvium cover. Geophysical

surveys were therefore undertaken to assist in target definitio n and included airborne magnetics and

a deep penetrating, ground IP survey. Three-dimensional modelling of all this data has highlighted the

presence of a zone of chargeabilit y highs associated with inter mediate resistive bodies which are

coincident with an intermediat e magnetic anomaly. The geophysic al anomalies demonstrate an

excellent coincidence with the CP Z as defined by geological map ping, soil and rock sampling. The

magnetic survey also highlights a clear, NE-SW trending structu ral corridor which is interpreted to

have facilitated emplacement of the CPZ and vein systems in between the various country rocks.
