Collective Mining to Begin Drilling at Orion,
a Newly Defined 2026 Target; Drilling at Victory Target to Follow in Q4-2026
- Exploration fieldwork in 2026 has defined the Orion target,
located approximately one kilometer east of the Apollo system and 300 meters east of the Plutus target
- Surface work at Orion has outlined a 350-meter by 300-meter
mineralized footprint with strong gold and silver geochemistry; rock samples returned values of up to 7.43 g/t gold, 230 g/t silver, 0.26%
copper, and 85 ppm molybdenum
- Reinterpretation of 2022 drilling results from the Victory
target has defined a new copper-gold-molybdenum porphyry-breccia target
- Both Orion and Victory locate coincident with discrete magnetic
high anomalies interpreted to represent potential intrusion sources at depth
- Drilling at Orion is set to commence this week, followed by
drilling at Victory in Q4-2026
MIAMI, Sept. 3, 2026 /CNW/ -- Collective Mining
Ltd. (NASDAQ: CNL) (TSX: CNL) ("Collective" or the "Company") is pleased to announce that generative
exploration fieldwork and a systematic review of satellite targets surrounding the Apollo system at the Guayabales Project in Caldas,
Colombia, has advanced the newly discovered Orion target to drill-ready status. The Company has also completed a reinterpretation of previous
exploration data at Victory, generating new porphyry-breccia and precious metal targets scheduled for drilling in Q4-2026.
Ari Sussman, Executive Chairman, commented: "Our
exploration team continues to demonstrate the significant prospectivity of the Guayabales Project. Orion is particularly compelling because
of the combination of sheeted and stockwork veining, strong gold and silver surface geochemistry and a discrete magnetic anomaly all occurring
within a favorable structural setting just one kilometer east of Apollo and 2 kilometers northwest of Aris Mining's Marmato mine. At Victory,
a fresh review of our previous drilling and exploration data has also generated an important new porphyry-breccia target that we plan
to test later this year.
With thirteen drill rigs now on site, a strong treasury
and a favorable commodity price backdrop, the time is right to push hard in exploration by continuing to grow our flagship Apollo system,
drilling the Trap system and testing earlier stage targets."
Details - Orion Porphyry Center (See Figures 1-2)
Orion is located approximately one kilometer east
of the Apollo system and 300 meters east of the Plutus target (see Figure 1). At surface, Orion is defined by a 350-meter by 300-meter
inlier of argillic- and sericite-altered quartz diorite containing moderate to high-density auriferous quartz-iron oxide sheeted and stockwork
veining. The target remains concealed beyond the currently mapped exposures by debris and colluvial cover, limiting the observable surface
footprint.
Orion is located within an interpreted zone of structural
complexity, where the northwest-trending Apollo-Marmato structural corridor intersects the prospective east-west striking Gustavo Fault
and its associated parallel splays. At surface, this structural intersection is expressed through abrupt changes to local stream directions
and uneven topography.
Reconnaissance surface sampling of the altered quartz
diorite and associated vein development has returned elevated gold, silver, copper and molybdenum values coincident with a discrete magnetic
susceptibility high. Results from surface sampling at Orion include:
- Gold in rock values up to 7.43 g/t, and gold in soil values of
up to 4.00 g/t;
- Silver in rock values up to 230 g/t and silver in soil values
of up to 21 g/t;
- Copper in rock values up to 0.26%, and copper in soil values up
to 0.06%; and
- Molybdenum in rock values up to 85 ppm, and molybdenum in soil
values up to 49 ppm
Surface mapping has identified porphyry-related mineralization
expressed as high-level sheeted and stockwork veining hosted within a magnetite-depleted argillic- and sericite- altered quartz diorite.
The mapped alteration occurs above a discrete magnetic susceptibility high, which is interpreted to represent a potential intrusion source
at depth.
Drilling at Orion is expected to commence this week
and will initially test beneath the strongest coincident surface geochemistry, alteration, veining and magnetic response.
Details – Victory Target (See Figures 1 &
3)
Review and reinterpretation of previous exploration
completed at the Victory target has generated new copper-gold-molybdenum porphyry-breccia and precious metal vein targets for follow-up
drilling. In 2022, Collective completed two diamond drill holes, VICW-1 and VICW-2, (See 2022 NI 43-101 Guayabales Technical Report) targeting
an interpreted copper-gold porphyry system beneath outcropping polymetallic veining and a discrete magnetic anomaly. Both holes intersected
multiple zones of high-grade precious metals veining, representing the at depth extensions of auriferous veins mapped at surface. Significant
intercepts included:
- 5.85 meters @ 2.95 g/t Au from 198.50 meters and 1.00 meter @
13.94 g/t Au from 261.40 meters in discrete vein zones from VICW-1
- 3.75 meters @ 3.21 g/t Au from 64.95 meters and 0.85 meters @
7.90 g/t Au from 307.75 meters in discrete vein zones from VICW-2
Importantly, drilling also intersected potassic alteration
characteristic of a higher-temperature porphyry environment. VICW-1 intersected K-feldspar-magnetite-quartz alteration with chalcopyrite
and molybdenite occurring within veins and breccia infill hosted in diorite porphyry between approximately 401 meters and 414 meters downhole.
This interval returned anomalous copper values of up to 0.12% and molybdenum values of up to 180 ppm. A similar altered diorite carrying
elevated copper and molybdenum was intersected in VICW-2 between 345 meters to 354 meters down hole.
Collective interprets these high-temperature alteration
assemblages and associated copper-molybdenum mineralization as potential vectors toward a more proximal porphyry source at depth. Follow-up
drilling will target interpreted continuation of the potassic-altered diorite and productive porphyry-breccia mineralization in Q4-2026.

Figure 2: Plan and Interpreted Sectional View of the Orion Target
The plan view highlights the mapped auriferous quartz-iron
oxide sheeted and stockwork vein development which is coincident with a gold-in-soil geochemistry anomaly and a magnetic high anomaly.
Surface gold geochemistry, related to the quartz-iron oxide stockwork veins, is also highlighted.
The A-A' sectional view illustrates the interpreted
depth extension of the surface alteration and vein development toward a potential porphyry source coincident with a discrete zone of elevated
magnetics. These positions will form the initial focus of drill testing as early as this week.

Figure 3: Plan and Interpreted Sectional View of the Victory Target
The plan view highlights the surface gold geochemistry
associated with quartz-magnetite-iron oxide veins within a sericite alteration halo, together with coincident elevated copper and
molybdenum in soils. The locations of historical drill holes VICW-1 and VICW-2 are also shown.
The B-B' sectional view illustrates the depth continuation
of surface alteration and vein development and also shows the zones of K-feldspar-magnetite-quartz alteration with chalcopyrite and molybdenite
intersected in VICW-01 and VICW-02. The interpreted continuation of this higher-temperature alteration and mineralization at depth will
form a primary target for follow-up drilling in Q4-2026.

Technical Information
Samples were cut by Company personnel at Collective
Mining's core facility in Caldas, Colombia. Diamond drill core was sawed and then sampled in maximum 2-meter intervals, stopping at geological
boundaries. Drill hole core diameter is a mix of PQ, HQ and NQ depending on the depth of the drill hole. Core samples have been prepared
and analyzed at ALS laboratory facilities in Medellin, Colombia and Lima, Peru for copper, gold and silver assays, and multi-element ICP.
ALS is an accredited laboratory which is independent of the Company. Gold assays are obtained by fire assay fusion with AAS finish on
a 50g sample (Au-AA24). Any samples returning > 10 g/t were then reanalyzed by fire assay with gravimetric finish on a 50g sample (Au-GRA22).
Copper and silver were assayed by inductively Coupled Plasma - Atomic Emission Spectroscopy (ICP-AES) and Mass Spectrometry (ICP-MS) following
a 4-acid digestion. Samples were also analyzed for a suite of 48 elements with ME-MS61 plus mercury and a sequential copper leach analysis
was completed on each sample with copper greater than 10,000 parts per million. Blanks, duplicates, and certified reference standards
are inserted into the sample stream to monitor laboratory performance. Crush rejects and pulps 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.
