Today's results from $CNL @CollectiveCNL mark a meaningful step in growing the footprint of the Apollo system.
We stepped out ~340 meters into a previously untested portion of the Ramp Zone's northwest breccia margin and intersected high-grade gold:
APC164-D4: 12.10 m @ 11.33 g/t AuEq
APC164-D3: 54.00 m @ 2.84 g/t AuEq, including 23.65 m @ 4.54 g/t AuEq
The Ramp Zone is a reduced intrusion-related gold system. Late-stage gold-rich veins fill the crackle breccia matrix. Because the crackle breccia phase is porous, gold-bearing fluids have more space to release their metal content, resulting in the high grades at Ramp. Importantly, today's intercepts indicate that the same mineralizing process responsible for the high-grade southeast Ramp Zone extends to the west and northwest margins of the breccia.
The key point of the news today: our geologists interpret these holes as having intersected only the upper portion of the system. Approximately 80 meters deeper, APC180-D4 logged 19 occurrences of visible gold over 62 metres of core. Assays are pending, and visual observations are not a substitute for assay results.
We also encountered new high-grade veins in untested ground that are not captured in any existing geological or block model, including 1.30 m @ 74.58 g/t AuEq in APC164-D4.
To date, approximately 590 meters of the 1.5 km breccia circumference has been tested, and only about 315 meters is included in the maiden resource.
With 13 rigs turning and assays pending for 95 holes (19 holes from the Ramp Zone), Apollo continues to flex its muscles as a rapidly expanding AuEq deposit. We will keep drilling until the geology shows us where the system ends, and every round of drilling so far has pushed that boundary further out.

Colombia's Interior Minister calls this one of the most important economic announcements in years… he may be understating it.
Under a draft decree, prior consultation and environmental licensing would advance in parallel instead of in sequence. Same technical standards, same respect for communities, but years taken out of the critical path.
Sequential approvals are the quiet reason new mines in Canada and the United States so often take a decade or more to permit. Each step waits for the last to finish, and the clock runs while the world needs more copper, gold and energy than ever.
In resources, time is the hidden cost of capital. Countries that run approvals in parallel, without lowering the bar, will win the next decade of investment… and Colombia is signalling it intends to be one of them.
@jrestrp @fabio_arjona @ANMColombia @CollectiveCNL @Collective_Col
Esta es una de las noticias económicas más importantes de los últimos años!
A partir de este decreto todos los grandes proyectos de inversión del país pueden arrancar inmediatamente!
Con @fabio_arjona presentamos el borrador de decreto de Ambiente que permite que la consulta previa y el licenciamiento ambiental avancen al mismo tiempo.
Lo que cambia: un proyecto ya no tiene que esperar años a que termine la consulta para empezar a tramitar su licencia ambiental. Puede avanzar en paralelo, sin rebajar la calidad técnica de los estudios.
El impacto es concreto:
• Sirius (el mayor hallazgo de gas de Colombia) puede adelantar su licencia mientras cierra las ~120 consultas previas.
• La Línea Colectora y los proyectos de energía de La Guajira dejan de perder años por el mismo cuello de botella.
• Obras de infraestructura vial y energética de todo el país pueden ahorrarse hasta dos años.
La consulta previa se respeta.
El tiempo perdido y el represamiento, no.
Esto es competitividad, seguridad energética y más oportunidades para Colombia. 🇨🇴

Scotiabank’s daily Mining Scoop from Mining Forum Americas just listed an “improving business environment in Colombia” among its key takeaways from corporate interactions.
That is how a jurisdiction goes mainstream… when the sell-side starts writing it down without hedging.
At $CNL we are not waiting for the narrative to catch up. Thirteen rigs are turning at Guayabales right now, including seven on the Ramp Zone. Dozens of holes are either underway or already drilled and awaiting assays.
Underground exploration adit construction is targeted for Q4 2026. Environmental license application in H2 2027. Updated Apollo resource in Q1 2028. PEA in H2 2028. Feasibility mid-2029. Early works and construction targeted for H2 2029.
When the backdrop improves, you accelerate. That is the plan.

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.

Colombia tiene una oportunidad histórica en el gobierno del presidente @ABDELAESPRIELLA: convertir nuestros minerales críticos en industria, empleo, desarrollo y oportunidades para nuestras comunidades.
Así lo expuse en la Cumbre de @ConcordiaSummit en Nueva York. América Latina vive un nuevo momento. Es hora de aprovechar nuestros recursos, impulsar una adición energética responsable y construir una economía más moderna y competitiva.
Eso es lo que significa la #MisiónCrecer. 👏🏼

Geology without governance is a museum. Governance without geology is a speech.
Colombia has both tracks aligned.
Robust geological potential with real money being spent to unlock future deposits, agile project development, and a clear invitation by the Vice President of Colombia @jrestrp to private capital - delivered to investors in New York today.
The time for Colombia to join the world's mining ranks is now!
@acmineriacol @CollectiveCNL ($CNL)
Uno de los primeros pronunciamientos del vicepresidente José Manuel Restrepo en su agenda con inversionistas en Nueva York tuvo lugar en el Concordia Annual Summit, donde destacó el potencial de Colombia para convertirse en un actor relevante dentro de las nuevas cadenas de suministro de minerales críticos.
El país ha dejado claro su compromiso de avanzar del potencial geológico al desarrollo ágil de proyectos, con reglas claras, participación privada y condiciones que aseguren inversiones sostenibles de largo plazo.

Collective Mining Delivers Maiden Resource Estimate Totaling More Than 5 Million Ounces AuEq, Market Unimpressed robertsinn.substack.com/p/co…
For junior mining companies, publishing a maiden mineral resource estimate (MRE) can be a blessing and a curse. On the plus side, it’s a key step in legitimizing your deposit(s) and helps to attract institutional investors who now have numbers to look at. However, the negative side is that it is virtually always a sell the news event in the market. In addition, some investors see the publishing of an MRE as confirmation that the company is moving into the feasibility/permitting stage of the Lassonde Curve—the dreaded “orphan period”.
The typical trading pattern is to buy the stock up ahead of the MRE or PEA, and then to sell the stock once the resource estimate or economic study is published. So far, trading in @CollectiveCNL (Nasdaq:CNL) is following this standard junior mining script.... $CNL

The positive momentum for Colombia (read through to $CNL) continues.
Yesterday, President Abelardo De La Espriella and U.S. Secretary of State Marco Rubio signed a critical minerals MOU between the two countries.
Relevant to this new MOU, @collectivemining plans to submit its environmental license application for the Apollo deposit in 2027. If approved, Apollo would be the first new mine in Colombia with critical minerals copper, silver, and tungsten to potentially feed the seemingly insatiable appetite of the U.S.
.@SecRubio signs two memoranda of understanding with Colombia about critical minerals and strategic civil nuclear cooperation.

El mantra en minería debe ser explorar, explorar y explorar.
Solo el 2,5 % del territorio está titulado para minería. En el resto, el 97%, sabemos que hay mucho potencial, pero no lo conocemos en detalle.
Para explorar se requieren reglas claras, garantizar condiciones de seguridad, combatir sin tregua la extracción ilegal y que los trámites ambientales no se conviertan en un palo en la rueda para la actividad legal.

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.

Just returned from Colombia after visiting $CNL’s Guayabales Project.
A lot is happening on the ground:
• Our exploration adit is on the cusp of beginning construction
• Drilling is going well, with plenty of assays due from the lab imminently
• Our maiden MRE is nearing completion for a September release
In this video, we’re walking the road to the future exploration adit portal location—an exciting next step as we prepare to take exploration underground.
The Balance of 2026 is going to be exciting at Guayabales. Stay tuned.

Today we ($CNL) reported very robust metallurgical recovery rates for our Apollo system. A shareholder reached out to me asking why were the copper recoveries only 85%
Answer is simple: the master composite grade (see image) for copper was low at only 0.08%! In the copper zone covering the top 500m of the Apollo system, the avg grade is significantly higher. In fact, when copper grades avg above 0.15%, we recover well over 90% in test work. Our copper mineral is only chalcopyrite with very low impurities.
