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 /PRNewswire/ - 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.

TORONTO , Nov. 10, 2025 /PRNewswire/ - Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) ("Collective" or the "Company") is excited to report that a multi-hole drill program is now in full swing, targeting the high-grade, outcropping tungsten-rich zone crowning the Apollo system ("Apollo").

TORONTO , Oct. 20, 2025 /PRNewswire/ - Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) ("Collective" or the "Company") is pleased to provide an exploration update and announce that visual inspection of new drill core from step-out drilling at the Guayabales Project's Ramp Zone (located at the bottom of the Apollo system) and the San Antonio Project's Pound target indicates that potentially significant mineralization has been intersected.

Two new holes have tested the high-grade Ramp Zone by intersecting wide and continuous intervals of reduced intrusion related gold mineralization. The Ramp Zone locates at the bottom of the Apollo system.

Two maiden holes drilled to the north and northwest respectively at the X target were directed to intercept robust soil and geophysical anomalies. Both holes cut multiple zones of silver dominant veins over a broad area measuring approximately 500 metres by 500 metres resulting in a new silver-rich discovery for the Company.

Latest drill results at San Antonio into the Pound target have expanded the footprint of the recently discovered porphyry system and intersected multiple mineralized zones: Hole SAC-18, located two hundred and fifty metres south of previously announced discovery hole SAC-11, was drilled vertically into a mineralized porphyry system and intersected: 172.40 metres @ 1.88 g/t gold equivalent (1.40 g/t Au, 0.16% Cu, 17 g/t Ag, 68 ppm Mo) including: 28.50 metres @ 3.32 g/t AuEq (2.05 g/t Au, 0.20% Cu, 62 g/t Ag, 12 ppm Mo) and 60.75 metres @ 2.27 g/t AuEq (2.05 g/t Au, 0.17% Cu, 4 g/t Ag, 98 ppm Mo) The hole was terminated prematurely while in strong mineralization due to the limitation of the rig with the final 1.60 metres averaging 2.03 g/t AuEq Hole SAC-15 was drilled to the south from the same pad as SAC-18 at a flatter angle and also intersected the same mineralized system returning: 154.20 metres @ 1.22 g/t gold equivalent (1.12 g/t Au, 0.03% Cu, 11 g/t Ag) including: 58.00 metres @ 2.15 g/t AuEq (1.95 g/t Au, 0.03% Cu, 21 g/t Ag) 16.05 metres @ 2.17 g/t AuEq (2.03 g/t Au, 0.08% Cu, 12 g/t Ag) SAC-15 also bottomed in strong mineralization due to the depth capacity limit of the rig with the final 9.90 meters averaging 3.18 g/t AuEq (2.99 g/t Au, 0.11% Cu, 17 g/t Ag). Three porphyry related mineralized phases have now been identified at the Pound target as follows: Phase 1 is a large, three by three-kilometre area covering the entirety of the San Antonio project displaying a phyllic altered, porphyry halo zone, which hosts low grade gold (0.2 g/t Au-0.5 g/t Au), extends from surface to a minimum of 700 metres depth and is open in all directions.

High-grade gold, copper, silver and tungsten assay results have been received for four holes from its ongoing shallow drilling program designed to outline and expand the near surface zone of mineralization at the Apollo system with highlighted results as follows : 183.70 metres @ 3.01 g/t gold equivalent  (0.86 g/t gold, 44 g/t silver, 0.83% copper and 0.14% WO3) from 37.30 metres downhole (APC-134) 37.15 metres @ 7.05 g/t gold equivalent  (2.19 g/t gold, 89 g/t silver, 0.92% copper, and 0.73% WO3) from 118.10 downhole (APC-136) The second large capacity diamond drill rig to test the Ramp Zone has arrived on site and is expected to begin operating within the next two weeks.
