Collective Mining Drills 534 g/t Gold & 40 g/t

Silver Over 0.65 Metres at the ME Target and

Commences Drilling on Multiple Apollo Look-

alike Targets Outlined by a New Gravity

Survey

A new high-grade vein system has been discovered in hole MEC-2 at the ME target

(located southeast of

Apollo

) with assay results as follows:

0.65 metres @ 534.0 g/t gold from 274.5 metres downhole and

0.90 metres @ 47.2 g/t gold from 291.8 metres downhole

Shortly after completing hole MEC-2 and at the onset of hole MEC-3, drilling was halted

as the preliminary results from the new gravimetric survey were received by the

Company, indicating that these holes were drilled outside of the gravity high. The

Company interprets the new discovery in hole MEC-2 to be high-grade vein leakage from

a potentially large, mineralized breccia body located within the gravity high to its

immediate south. Drilling has recommenced at ME targeting the gravity high with

additional results expected in due course.

A new gravimetric survey was completed over a two-square-kilometre portion of the

Guayabales Project covering the corridor running from the

Apollo

system to the

concession boundary with Aris Mining's Marmato mine with compelling highlights as

follows:

Confidence in the survey is robust as it proved extremely effective in identifying

Apollo

as a gravity-high due to the high concentration of breccia hosted

sulphides in the system.

Seven new gravity anomalies, with near-identical gravimetric features to

Apollo

,

have been identified within the survey corridor including one located directly

southwest of

Apollo

named Apollo South, three in the ME target area, one in the

X target area and two in the Plutus target area.

Diamond drilling with two rigs to test both the ME and X gravimetric high

anomalies will commence immediately with the balance of the gravity targets to

be tested shortly thereafter.

/CNW/ -

Collective Mining Ltd.

(NYSE: CNL) (TSX: CNL)

("Collective"

or the "Company")

is pleased to announce that it has discovered a high-grade vein system at the

ME target and the completion of a gravimetric survey on the southeastern portion of Guayabales

Project surrounding the

Apollo

system ("Apollo"). The aim of the survey was to highlight potential

targets with

Apollo

style mineralization within the northwest trending

Apollo

-to-Marmato corridor.

Apollo

is the most advanced discovery made to date within the Company's multi-target, Guayabales

Project in Caldas,

Colombia

.

The Company currently has nine drill rigs operating as part of its fully funded 70,000 metre drill

program for 2025 with seven rigs operating at the Guayabales Project and two rigs turning at the

San Antonio Project. Two additional deep capacity rigs are being mobilized to the Guayabales

Project to resume testing the high-grade Ramp Zone located at the bottom of the

Apollo

system in

Q3, 2025.

Approximately 128,000 metres of diamond drilling has been completed to date at the Guayabales

Project, including 90,000 metres at

Apollo

. There are currently twenty-nine drill holes in the lab with

assay results for most of these holes expected in the near term.

Ari Sussman

, Executive Chairman commented: "The results from the gravity survey are truly exciting.

In fact, I believe that the gravity survey is the key breakthrough required to find another

Apollo

system as large porphyry related funnel breccia bodies (like

Apollo

) are almost always found in

clusters. We are going to aggressively drill as many of the gravity targets as feasible this year and

are hopeful that we will be able to deliver another discovery before the end of 2025. The high-grade

veins encountered through drilling at the early-stage ME target are very encouraging as they are

indicative of a fertile environment for metal deposition. I am excited to be drilling the ME gravity

anomaly due south of this hole as our team believes we have a chance at finding a bulk tonnage,

mineralized breccia body. With giant hydrothermal systems encompassing both our Guayabales and

San Antonio

projects and nine rigs turning across the portfolio, our chances of making the next big

discovery to complement

Apollo

have never been stronger."

ME Target Drilling

Diamond Hole MEC-2 was drilled to the northeast from Pad ME3 and was directed to intercept the

projection of a high-grade geochemical signature encountered at surface. The hole discovered a new

high-grade vein system hosted within porphyry quartz diorite and diorite and encountered some

sections of crackle and brecciated textures permeated with a mix of sulphides including chalcopyrite,

pyrite, sphalerite and galena. Significant assays result for hole MEC-2 are presented below:

0.65 metres @ 534.0 g/t Au and 40 g/t Ag and

0.90 metres @ 47.20 g/t Au and 8 g/t Ag

After completion of drill-hole MEC-2 and at the early onset of hole MEC-3, the Company received

preliminary results of the gravimetric survey (details provided in the section below) which show that

hole MEC-2 drilled into a gravity low located just outside a large gravity high anomaly now known as

the ME gravity anomaly. As a result, drilling of MEC-3 was immediately terminated due to it being

directed outside of the gravimetric target. The Company believes that the gravimetric target is a

potentially large breccia body enriched in sulphides. Follow up drilling has commenced with results

expected in due course.

Gravimetric Survey Details

A gravimetric geophysical program was completed by ARCE GEOFICOS SAC in

June 2025

and

covered a total area of 2 km

2

with 414 stations arranged on 50 metres east-west by 100 metres

north-south grid. The primary objective of the program was to detect high-density sulphide bearing

bodies, similar to

Apollo

from surface to the maximum depth detection limit of 800 metres.

The method consists of measuring variations in the Earth's gravitational field to detect anomalies

associated with changes in the density of sub-surface rocks enabling inference of known mineralized

bodies like

Apollo

.

The initial phase of the gravimetric survey was focused on the Company's flagship

Apollo

discovery,

and as expected a high-density gravity signature was found which represents the high-grade,

sulphide rich, Au-Ag-Cu-W breccia system. Due to the excellent and clear definition of the gravity

high at

Apollo

, the survey was extended to over a two-kilometre square area covering the northwest

trending corridor from the

Apollo

system to the concession boundary with Aris Mining's multi-million-

ounce Marmato mine.

The second phase of the gravimetric survey expanded the coverage area to encompass the

northwest corridor beginning from the concession boundary with the Marmato mine and culminating

slightly northwest of

Apollo

. Results of the total gravimetric survey highlight seven additional and

similar gravimetric anomalies to

Apollo

, all of which are undrilled and commence from or near the

surface.

Seven new major gravimetric highs have been identified with near identical properties to the

gravimetric high at

Apollo

. Like

Apollo

, each of these new gravimetric highs begins at or near surface

and continues down vertically to the survey depth limit. The names of these new gravity targets are

Apollo South, X, ME, ME South 1, ME South 2, Plutus 1 and Plutus 2. The Company is prioritizing

two diamond rigs to test all the newly generated gravity anomalies with drilling at the ME target now

underway and drilling at X expected to commence shortly.

A detailed summary of the various gravimetric targets is as follows:

The Apollo South gravity anomaly is a new target located a mere 250 metres southwest

of the Company's flagship

Apollo

system. The gravimetric characteristics of the anomaly

are identical to

Apollo

with Apollo South potentially being the other half of the

Apollo

system.

The X gravity anomaly is another greenfield target located 1 km south of

Apollo

within

the X Target area. A maiden drill program at the X target is expected to commence in

two weeks with drilling to target an outcropping mineralized breccia body on the flank of

the gravimetric high anomaly.

The ME gravity anomaly and the two ME South gravity anomalies are located between

0.6 kilometre and 1 kilometre to the southeast of

Apollo

. All three anomalies share

similar characteristics to the gravity anomaly covering the

Apollo

system with drilling

now underway to test the ME gravity anomaly.

The greenfield Plutus gravity anomalies 1 and 2 are located up to one kilometre east of

Apollo

. The Plutus 1 anomaly is of particular interest given its large size and continuity

of over 700 vertical metres. Previous surface sampling above the anomaly has

encountered strong quartz diorite hosted gold-copper porphyry mineralization.

Other

The Company completed three diamond drill holes into the Tower target area and failed to encounter

any significant mineralization. Additionally, it is now clear from the gravimetric survey that the Tower

target locates in a gravity low. As a result, the Tower target has been downgraded, and no further

drilling is contemplated in the future.
