🚨 Rigs mobilizing at Trap – new drill campaign launching in May!

Our team is on the ground at the Trap Target, just 3.5 km northeast of Apollo, preparing two diamond rigs for a major new program.

Trap was discovered through ~18,000 m of prior drilling that delivered standout results, including:
* 40.50 m @ 4.01 g/t AuEq from 164.90m down hole (TRC-30)
* 632.25m @ 1.10 g/t AuEq from 172.65m down hole (TRC-7A)
* 301.50m @ 1.01 g/t AuEq from 19.50m down hole (TRC-2)

Now we’re stepping out aggressively to test:
* A potential 850 m northwest extension to the 1,400 m high-grade sheeted-vein corridor (open in all directions)
* A new large-scale gold-copper porphyry anomaly with strong coincident mineralization

Another shot at a high-impact catalyst for $CNL shareholders as we unlock Trap’s full potential.

Stay tuned — drilling starts this month!

💡Collective Mining’s Apollo system continues to deliver strong drill results, with 18 intercepts exceeding 1000 g/t AuEq on a gram x metre basis, the most of any active gold explorer globally since 2022.

- In January 2026, hole APC143-D3 entered the top-5 when we intercepted 58.13m @ 21.33g/t Au (1,239 g/t Au (gram x metres), the highest gram x metre intercept drilled at the Ramp Zone to date.

- Apollo has now been defined over approximately 1,050m of strike, 400m width and 1,450m vertical extent, and remains open in multiple directions.

Wrapping up #PDAC2026 with great engagement from investors and industry peers.

The Collective Mining team was pleased to showcase drill core from the Apollo discovery and discuss ongoing exploration activities at the Guayabales Project in Colombia.

Thank you to everyone who took the time to stop by and connect with our team.

Ari Sussman, Executive Chairman of Collective Mining, presented an update to investors on the Apollo discovery during a session hosted by PowerOne Capital Markets during #PDAC2026 in Toronto.

The presentation highlighted ongoing drilling success at Apollo, and the potential exploration upside across the Guayabales Project in Colombia.

We are officially live at #PDAC2026! We invite investors, geologists, and industry partners to visit Collective Mining at our two key locations:

- Core Shack (Booth 3114A): Get a close-up look at the recent drill core from the Apollo System and examine the mineralization firsthand.

- Investor Exchange (Booth 2138): Connect with our leadership team to discuss our latest operational milestones and 2026 outlook.

Come see the physical evidence of our work in Colombia. We look forward to seeing you there!

$CNL | Collective Mining is pleased to display drill core from the high-grade Ramp Zone at the upcoming #PDAC2026 Core Shack Session. ✅ Highlighted results include 58.10m @ 21.33 g/t Au from the deepest hole ever drilled at the project.

Visit us at Booth 3114A on March 1–2. We look forward to connecting in Toronto!

🎙️ We are pleased to share that our Chairman, Ari Sussman (@Ariski73), was interviewed today by Trevor Hall (@TrevAHall) on Mining Stock Daily. The discussion covered key developments and upcoming catalysts at our Guayabales and San Antonio projects.

A standout highlight from the interview is Ari's emphasis on the remarkable results from recent drilling. Notably, step-out hole APC-159 intersected high-grade mineralization at surface, yielding 30.70 meters @ 17.35 g/t AuEq within a broader interval of 165.75 meters @ 5.65 g/t AuEq (announced today).

Additionally, we encountered very high-grade mineralization approximately 1.4 km below surface in the Ramp Zone, where hole APC-143-D3 cut 58.10 meters @ 21.33 g/t gold (announced January 27).

[Ari Sussman @Ariski73]

The positive surprises keep on coming for $CNL. We decided to step out with the final hole on the drill pad and hit shallow, very high-grade mineralization, while extending the Apollo breccia body to the NE.

31.70m @ 17.35 g/t AuEq Within 165.75m @ 5.35 g/t AuEq from 8.85m

This is a virgin area for drilling (red circle on the image), and we intend to quickly move a rig into the zone and look to extend the high-grade both within the breccia and outside it in the Hanging Wall Vein Zone!

[Ari Sussman @Ariski73]

Today we ($CNL) announced our highest-grade assay to date from a step-out hole at depth in the Ramp Zone by intersecting:

58.10m @ 21.33 g/t Au including;
27.00m @ 43.13 g/t Au

Many of you have reached out for more details on the revised geological model we introduced in the release, which suggests the Ramp Zone could extend around the circumference of our large breccia system. Let's dig in:

1. If the breccia model is correct, we have tested 300m of strike with potential for an additional 1,200m to find more mineralization

2. Ramp Zone gold is primarily hosted in crackle breccia, typically located along the outer/upper margins of large breccia systems.

3. To clarify: We've conducted zero drilling elsewhere around the breccia margins at the Ramp Zone's elevation. The plan view shared is at 750 MASL, with the circumference projected from shallower holes—only future drilling can confirm the exact boundaries.

4. Since the upper Apollo system is mineralized throughout, there's strong potential for the outer breccia margins at Ramp Zone depths to be similarly mineralized.

5. In the mother drill holes for Ramp (which have intersected the breccia's northern margin at shallower elevations above Ramp's start), trace element assays (e.g., bismuth and tellurium) show early windows of Ramp-style mineralization. We're optimistic these could develop into higher-grade zones at 1000 MASL or deeper, which is the elevation for which Ramp Zone begins.

🚀 As we kick off 2026, Collective Mining is geared up to expand the Guayabales project’s Apollo system in the Ramp Zone & Northern Hanging Wall Zone. We’ll revisit the Trap target with fresh drilling, and keep pushing at the San Antonio project, site of our 2025 copper and silver rich discoveries! Fully funded for 100,000m+ of drilling. Check out Chairman Ari Sussman (@Ariski73) live from site in the video!

[Collective Mining - CNL on the NYSE & TSX @CollectiveCNL]

After a blockbuster 2025 full of high-grade discoveries (including the highest-grade intercept ever at Apollo: 24.8m @ 29.42 g/t Au!), 2026 is all about scale.

The deeper Ramp Zone reactivation is fueling potential growth — with a fully funded ~100,000m drill program ahead and a more advanced maiden resource on the horizon.
