Collective Mining Announces a 200 Metre Strike Extension at the Ramp Zone with Results Including 50.50 Metres at 5.66 g/t Gold and 13 g/t Silver

Executive Summary

• Two new drill holes (APC103‑D6 and APC106‑D2) intersected the high‑grade Ramp Zone, extending it ~200 m along strike and confirming continuity of mineralization.
• Hole APC103‑D6 returned 50.50 m @ 5.66 g/t Au and 13 g/t Ag (including 8.80 m @ 10.56 g/t Au).
• Hole APC106‑D2, the deepest to date, returned 70.00 m @ 2.00 g/t Au and 5 g/t Ag (including 8.00 m @ 3.52 g/t Au).

Key Details

• Ramp Zone Extension:
• APC103‑D6 extended the zone laterally ~50 m NE; APC106‑D2 extended it ~200 m east and deeper to ~1,300 m below surface.

• Overall defined area now ≈275 m strike × 200 m vertical, open in all directions.

• Assay Results – Hole APC103‑D6:

• Total intersect: 50.50 m @ 5.66 g/t Au, 13 g/t Ag (526.10–576.60 m).

• Sub‑intervals:

  • 8.80 m @ 10.56 g/t Au, 23 g/t Ag (528.20–537.00 m)
  • 17.95 m @ 9.48 g/t Au, 18 g/t Ag (545.05–563.00 m)

• Assay Results – Hole APC106‑D2:

• Total intersect: 70.00 m @ 2.00 g/t Au, 5 g/t Ag (693.80–763.80 m).

• Sub‑intervals:

  • 8.00 m @ 3.52 g/t Au, 8 g/t Ag (711.00–719.00 m)
  • 25.05 m @ 3.44 g/t Au, 7 g/t Ag (738.75–763.80 m)

• Program Status:

• Treasury: ≈US$70.6 M as of Q2‑2025.
• Fully funded 2025 drill program: 70,000 m total; 10 rigs active (7 at Guayabales, 3 at San Antonio).

• To date: ~137,000 m drilled at Guayabales (97,000 m at Apollo); 16 holes in lab with results pending.

• Future Drilling Intent:

• Two large‑capacity rigs currently drilling; first directional hole (APC‑140D1) already intersected potential mineralization.

• Goal: extend Ramp Zone an additional ≥200 m vertically and laterally.

• Comparative Context:

• Company likens Ramp Zone to Aris Mining’s Marmato Deeps deposit (≈3.76 Moz Au measured‑indicated).

• Early grades at Ramp Zone are higher than those at Marmato Deeps, attributed to breccia host and overprinting high‑grade porphyry veins.

• Surface & Mineral Rights Acquisition:

• Additional surface rights secured for infrastructure; payment schedule US$4.75 M (Q4‑2025) + US$0.9375 M annually through 2029.

• New mineral titles acquired; payment schedule US$2.8 M (Q4‑2025) + US$1.48 M annually through 2030.

• Qualified Person: David J. Reading, QP under NI 43‑101, reviewed and approved technical information.

Notable Quotes

“We are highly encouraged by the results today and are optimistic that drilling will continue to validate our thesis that the Ramp Zone could have dimensions similar to Aris Mining's multi‑million‑ounce Marmato Deeps deposit.” – Ari Sussman, Executive Chairman
