Collective Mining Drills High-Grade Gold and Tungsten from Surface, Including 111.15 Metres at 5.48 g/t Gold Equivalent at Apollo

• High-grade gold, tungsten, silver and copper mineralization have been confirmed from surface in four new drill holes demonstrating strong vertical continuity within the upper levels of the Apollo system. Key intercepts include:
  
  
  • 111.15 metres @ 5.48 g/t gold equivalent (4.63 g/t gold, 0.17% WO₃, 14 g/t silver and 0.11% copper) from 2.00 metres including a high-grade subzone of 10.85 metres @ 41.45 g/t gold equivalent (38.52 g/t gold, 0.82% WO₃, 36 g/t silver and 0.22% copper) (APC-154)­
    
    
  • 113.65 metres @ 2.66 g/t gold equivalent (1.28 g/t gold, 0.22% WO₃, 25 g/t silver and 0.15% copper) from 4.60 metres including 55.40 metres @ 4.72 g/t gold equivalent (2.09 g/t gold, 0.45% WO₃, 43 g/t silver and 0.26% copper) (APC-152)
    
    
• All four holes announced today have intercepted higher gold and tungsten grades than those observed within the internal block model, which should in turn, positively impact locally on the upcoming maiden mineral resource estimate scheduled for early 2027.

Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) ("Collective" or the "Company") is pleased to announce assay results for four diamond drill holes targeting the high-grade, outcropping tungsten-rich zone at the summit of the Apollo system ("Apollo"). Apollo forms part of a large, partially reduced intrusion related system enriched in gold, silver, copper and tungsten. Drilling to date has delineated continuous mineralization from surface to depths exceeding 1,400 vertical metres, where the high-grade Ramp Zone remains open for further expansion. 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 exceptional near-surface results from Pad 33 significantly enhance the grade and continuity of the gold and tungsten-rich crown at Apollo. The impressive intercepts, including standout high-grade zones with visible scheelite (tungsten) and gold in some pending assay results, underscore the system's potential to deliver substantial value in both precious and critical metals. With strong tungsten grades complementing the gold, silver and copper endowment, Apollo continues to stand out as a unique and compelling discovery."

To date, Collective has completed 165,500 metres of diamond drilling across the Guayabales and San Antonio projects, including 109,000 metres at the flagship Apollo system.

With US$135 million in cash (as of December 1, 2025), the Company is fully funded for its planned 2026 program, which envisions up to 100,000 metres of additional drilling. Up to fourteen rigs are anticipated to be operating across both projects before the end of Q1, 2026, with numerous high-priority holes pending assay results.

Details (see Table 1 and Figures 1-5)

• Four drill holes collared from Pad 33 intersected high-grade gold, tungsten, silver and copper mineralization starting at or almost at surface with results as follows:
  
  
  • 94.75 metres @ 0.27% WO₃Eq from 3.20 metres down hole (APC-149) including:
    • 20.85 metres @ 0.55% WO₃Eq from 46.15 metres down hole
      
      
  • 113.65 metres @ 2.66 g/t AuEq from 4.60 metres down hole (APC-152) including:
    • 55.40 metres @ 4.72 g/t AuEq from 54.90 metres down hole
      
      
  • 168.00 metres @ 2.11 g/t gold equivalent from 4.50 metres down hole (APC-153) including:
    • 19.45 metres @ 3.01 g/t gold equivalent from 25.10 metres down hole
    • 18.00 metres @ 3.11 g/t gold equivalent from 59.00 metres down hole
    • 14.60 metres @ 3.01 g/t gold equivalent from 150.05 metres down hole
      
      
  • 111.15 metres @ 5.48 g/t gold equivalent from 2.00 metres down hole (APC-154) including:
    • 42.25 metres @ 12.13 g/t gold equivalent from 64.85 metres down hole
    • 10.85 metres @ 41.45 g/t gold equivalent from 64.85 metres down hole
      
      
• The shallow intercepts from Pad 33 have increased the local gold and tungsten grades by up to 25% in this area and successfully closed drilling gaps within the internal block model. Drill spacing in this area, from surface down to 150 metres depth, now measures 35 metres.
  
  
• An additional six diamond drill holes from the same shallow drilling program are in the lab awaiting results. Visible scheelite (a tungsten mineral) and visible gold have been observed in some of these additional holes (See Figure 3 and Figure 4 for further details).

These results reinforce Apollo's status as a robust exploration discovery with multi-metal upside. The Company remains focused on aggressive expansion and delineation drilling to unlock further value ahead of a planned maiden mineral resource estimate in early 2027.

X Target

Drilling at the X target has intersected narrow silver rich zones of veins with results as follows:

• XTC-3:
  • 1.05 metres @ 72 g/t silver equivalent from 163.15 metres down hole and
  • 3.25 metres @ 123 g/t silver equivalent from 190.95 metres down hole
    
    
• XTC-4:
  • 25.80 metres @ 75 g/t silver equivalent from 202.00 metres down hole including
    • 5.00 metres @ 165 g/t silver equivalent and
    • 3.15 metres @ 260 g/t silver equivalent
      
      
• Drill Hole XTC-5:
  • 1.20 metres @ 138 g/t silver equivalent from 34.60 metres down hole and
  • 1.30 metres @ 121 g/t silver equivalent from 189.55 metres down hole

Although results indicate a new mineralized system is present at X, the density of the veins is not robust enough to delineate a large deposit and as such no additional drilling is planned in the near term.

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 metres 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.
