**Collective Mining Expands Apollo System's Ramp Zone Along Strike and at Depth with High-Grade Drill Results Including 23.35 Metres @ 8.24 g/t Gold Within 76.10 Metres @ 3.26 g/t Gold**

***Three new drill holes confirm broad and continuous intervals of reduced intrusion-related gold mineralization extending the Ramp Zone to 300 metres of strike by 270 metres vertical - open in all directions***

TORONTO, Dec. 3, 2025 /CNW/ - **Collective Mining Ltd.** (NYSE: CNL) (TSX: CNL) **("Collective" or the "Company")** is pleased to announce assay results for three orthogonal diamond drill holes designed to continue expanding the high-grade Ramp Zone ("Ramp") along strike northwards and depth. The Ramp Zone is located at the bottom of the Apollo system ("Apollo") beginning at approximately 1,000 meters above sea level. Apollo is a large, partially Reduced Intrusion Related System enriched in gold, silver, copper, and tungsten. Drilling to date at Apollo has outlined continuous mineralization from surface to **more than 1,370 vertical metres**, where the high-grade **Ramp Zone remains open in all directions**. Apollo anchors the Company's flagship Guayabales Project - a district-scale, multi-target, and infrastructure-rich project in Caldas, Colombia.

Ari Sussman, Executive Chairman commented: "These latest drill results continue to highlight the Ramp Zone's impressive scale and high-grade potential. Hole APC143-D1, our deepest intercept to date in this area, not only extends the zone along strike and at depth but also demonstrates consistent mineralization over substantial widths. With additional rigs now on site and more assays pending (including two holes with significant visible gold flakes logged), we're excited to accelerate our exploration efforts and unlock further value at Apollo."

**Key Highlights (see Table 1 and Figures 1-6)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Hole APC143-D1: The deepest and northeastern most hole drilled into the Ramp Zone to date, intersected 23.35 meters @ 8.24 g/t gold and 8 g/t silver within a broader interval of 76.10 meters @ 3.26 g/t gold and 4 g/t silver from 409.60 meters downhole. This intercept has expanded the Ramp Zone's dimensions beginning approximately 1,000 meters above sea level to 300 meters of strike by 270 meters vertical (previously 275 meters strike by 200 meters vertical). The Ramp Zone remains open in all directions.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Hole APC140-D2: Locally extended the Ramp Zone by 50 meters to the northwest by cutting 16.40 meters @ 8.44 g/t gold and 19 g/t silver within 55.10 metres @ 3.06 g/t gold and 7 g/t silver from 243.1 meters downhole.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Pending Assays: Two additional drill holes into the Ramp Zone (APC143-D2 and APC143-D3) have collectively intersected 18 sightings of visible gold. These holes were specifically designed to further extend Ramp Zone's strike and depth. In comparison, no visible gold was observed in the drill holes reported today.** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **A third deep-capacity diamond rig is now turning at Ramp with an 850-meter mother hole complete and a series of directed daughter holes about to begin; two additional deep capacity rigs are also under contract for mid-Q1 2026 arrival to site.** 

To date, Collective Mining has completed **150,000 metres** of diamond drilling across the Guayabales and San Antonio projects, including **105,000 metres** at the flagship Apollo system. **Ten rigs** are currently turning, with multiple high-priority holes at both projects pending assays.

With **US$135 million** in cash (as of December 1, 2025), the Company is fully funded for its planned, aggressive **2026 program**, which targets up to **100,000 metres** of additional drilling.

**Details (see Table 1 and Figures 1-6)**

APC143-D1 was drilled as a wedge hole from new mother hole APC-143D from Pad 19 in a southerly direction and successfully extended the Ramp Zone 70 metres vertically beyond all prior drilling with assays results as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **76.10 metres @ 3.26 g/t gold, 4 g/t silver from 409.60 metres downhole including 23.35 metres @ 8.24 g/t gold, 8 g/t silver from 427.30 metres downhole** 

APC140-D1 and APC140-D2 were drilled as wedge holes from new mother hole APC-140D from Pad 29 to the south and southwest, respectively, at the same elevation and 50 metres apart. APC140-D2 is the northwesternmost hole ever drilled at Ramp and intersected the Ramp Zone 50 metres to the northwest from drillhole APC140-D1 with assays results as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **47.70 metres @ 1.98 g/t gold, 5 g/t silver from 527.40 meters downhole including 15.15 meters @ 3.00 g/t gold, 8 g/t silver from 559.95 metres downhole and 14.15 metres @ 2.13 g/t gold, 4 g/t silver from 598.55 meters downhole (APC140-D1)** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **55.10 metres @ 3.06 g/t gold, 7 g/t silver from 243.10 metres downhole including 16.40 metres @ 8.44 g/t gold, 19 g/t silver from 248.75 meters downhole (APC140-D2)** 

The aim of the current drill program at Ramp is to try and extend the system by multi-hundreds of metres in dimensions both vertically and laterally.

The continued presence of Ramp Zone mineralization at least 270 metres beneath the initial discovery at 1,000 MASL underscores the strong potential for expansion at depth and supports the view that drilling to date may have only tested the top of a large intrusion related gold system that shares similarities in mineralogy with the multi-million ounce, Marmato Deeps Zone located 1.75 km SE of Apollo.

*True widths have been estimated to be between 85%-98% of the total length with no grade capping applied. Internal dilution of up to 15% below a cutoff grade of 0.30 g/t Au may be included within intervals with the dilution not exceeding 5% continuously within the total interval.*

**About Collective Mining Ltd.**

To see our latest corporate presentation and related information, please visit www.collectivemining.com.

Founded by the team that developed and sold Continental Gold Inc. to Zijin Mining for approximately $2 billion in enterprise value, Collective is a gold, silver, copper and tungsten exploration company with projects in Caldas, Colombia. The Company has options to acquire 100% interest in two projects located directly within an established mining camp with ten fully permitted and operating mines.

The Company's flagship project, Guayabales, is anchored by the Apollo system, which hosts the large-scale, bulk-tonnage and high-grade gold-silver-copper-tungsten Apollo system. The Company's objectives at the Guayabales Project are to expand the newly discovered high-grade Ramp Zone along strike and to depth and drill a series of greenfield generated targets on the property.

Additionally, the Company has launched its largest drilling campaign in history at the San Antonio Project as it hunts for new discoveries and looks to expand upon the newly discovered porphyry system at the Pound target. The San Antonio Project is located between two to five kilometers east-northeast of the Guayabales Project and could potentially share infrastructure given their proximity to each other.

Management, insiders, a strategic investor and close family and friends own 45.3% of the outstanding shares of the Company and as a result, are fully aligned with shareholders. The Company is listed on both the NYSE American and TSX under the trading symbol "CNL".
