Since we announced Apollo’s maiden Mineral Resource on September 8, shareholders have been asking me: where does Apollo grow from here?

This cross section shows why we’re excited about the potential. The highlighted spaces between the model blocks reflect limited or no drilling—areas where further drilling could unlock growth. Also, as everyone knows, we are growing at depth in the Ramp Zone. Check out the cross section image 👇 $CNL

Today’s results include a new high-grade tungsten-gold discovery outside the Apollo breccia: 8.15m @ 0.40% WO₃ and 8.47 g/t gold.

With the U.S. and Colombia recently signing a framework to strengthen critical-mineral supply chains, finding more tungsten in Colombia is especially timely.

Plus 13 new high-grade veins, 7 of which are outside the block model including:

• 1.15m @ 57.98 g/t AuEq
• 1.25m @ 28.73 g/t AuEq

The next chapter is in the drilling: 13 rigs turning across Guayabales and 96 drill holes awaiting assays.

$CNL has just announced Apollo’s maiden mineral resource… a proud day for our team, but certainly not a moment to stand still.

What excites me is not simply the scale of this first estimate… it is the combination of scale, grade, a surprising large, high-grade open pit with a low strip ratio, the high-grade at the Ramp Zone, and the opportunity to keep growing.

We see a favorable backdrop in Colombia… and we are positioning Collective to seize that opportunity. We deliberately accelerated this maiden Mineral Resource so we could, in turn, accelerate the project’s path toward licensing—with submission of our environmental licence application now targeted for H2 2027. We are not waiting to finish discovering before doing the work needed to advance responsibly toward development.

And there is plenty more discovery work ahead… approximately 40,000 metres of additional drilling have already been completed since the March 31, 2026 database cut-off. None are included in today’s estimate.

With 13 rigs operating across Guayabales, we are pursuing that opportunity aggressively. Exploration, engineering and environmental work are advancing together… growing the resource while building the foundation for the project’s next chapter.

For our shareholders, our team and our partners in Colombia, today is a milestone worth celebrating. For me, it is also a powerful incentive to push harder.

Many have asked me what Colombia's mining sector will look like under the new government. It's go time. Colombia is about to become LatAm's latest hot mining destination.

Vice President Restrepo just put mining back where it belongs: a strategic sector for development, employment, and investment, done responsibly. Collective Mining ($CNL) is going to be one of the key pillars of Colombia's economic growth engine and the first hard rock producer of tungsten, a key critical mineral.

What a nice surprise while visiting $CNL in Caldas, Colombia — the assay results for Apollo’s new northern breccia extension arrived while I was there.

Watch the video for the full story, but a few quick highlights from today’s release:

• 100-metre northern extension to the Apollo breccia body at ~1,000 MASL

• 141.40m @ 4.88 g/t AuEq, including 38.00m @ 15.46 g/t AuEq

• A 170-metre vertical extension to the Apollo system

• Follow-up hole APC180-D1 has already cut up to 100m of prospective visual mineralization ~100m to the west — assays pending

And the best part? We weren’t even targeting this new breccia extension. The holes were on their way to test the Ramp Zone (assay results pending).

Apollo continues to surprise us.

Collective Mining reports 54.55 m at 7.04 g/t as ramp expands toward 2027 resource | Ari Sussman

@CollectiveMini1 (TSX: CNL; NYSE American: CNL) Executive Chair Ari Sussman says new drilling at the Ramp Zone within the Guayabales Project in Colombia continues to confirm high-grade continuity as the company advances toward a maiden mineral resource estimate targeted for the first half of 2027...

🎙️ 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).

This one has the ear marks of another big system in the making.

Lots more to come!

For those loving the #tungsten bull market underway with prices hitting decade+ highs at $500/MTU we at $CNL announced what must be one of the best tungsten drill intercepts this cycle cutting 37.15m @ 0.73% WO3, 2.19 g/t Au, 0.92% Cu & 89 g/t Ag

[Ari Sussman @Ariski73]

Two shareholders asked me why is $CNL drilling the San Antonio project (2 rigs) when we have a major discovery in Apollo (Guayabales project)?

Answer: How can we ignore a potentially giant system located next to the Pan American highway and hydroelectric power lines only a few km’s away from Guayabales?

San Antonio is without question a big & intensely altered system with porphyry style mineralization traced for more than 3km with the following attributes:

1. Multiple styles of porphyry related mineralization encountered through drilling incl. copper and gold porphyry mineralization, late stage CBM veins and sulfosalts.

2. Hole SAC-11 discovered a porphyry system by intersecting 290.2m @ 0.58 g/t Au, 3 g/t Ag and 0.17% Cu. We are hunting for the source of this mineralization

3. We continue to cut potential mineralization in subsequent follow up holes. See the video below of drill core tray from a recent hole cutting intense altered rocks enriched in sulphides. Caution** wait for assay results, which are expected in August.

The prize at San Antonio is potentially very large, a nice complement to our Apollo system. If we find a deposit at San Antonio, could it feed the same mill as Apollo?
