• High-grade gold, copper, silver and tungsten assay results have been received for the further six holes from the shallow drilling program designed to outline and expand the zone of mineralization with highlighted results as follows:
  • 397.50 metres @ 2.62 g/t gold equivalent (1.20 g/t gold, 60 g/t silver, 0.33% copper and 0.07% WO₃) from surface (APC-122) with a grade accumulation of 1,041 gram x metres. The hole bottomed while still in strong mineralization.
  • 135.20 metres @ 2.71 g/t gold equivalent (0.66 g/t gold, 50 g/t silver, 0.67% copper, and 0.15% WO₃) from surface (APC-119)

Collective Mining Ltd. (NYSE: CNL) (TSX: CNL) is pleased to announce assay results for six diamond drill holes designed to better outline and expand the shallow portion of gold-silver-copper-tungsten mineralization at the Apollo system. Apollo, which begins at surface and is strongly mineralized over 1,200 vertical metres and open at depth, is the most advanced discovery made to date within the Company’s multi-target, Guayabales project in Caldas, Colombia.

The Company currently has nine drill rigs operating as part of its fully funded 70,000 metre drill program for 2025 with seven rigs operating at the Guayabales Project and two rigs turning at the San Antonio Project. Drilling in the Guayabales Project is focusing on defining the shallow mineralization, high-grade sub-zones, expanding the high-grade Ramp Zone at depth and testing a series of Apollo look-alike gravity targets which were announced recently (see press release dated June 30, 2025). Two additional deep capacity rigs are being mobilized to resume testing the high-grade Ramp Zone with the first of these rigs expected to begin operations by early August 2025.

Approximately 129,500 metres of diamond drilling has been completed to date at the Guayabales Project, including 91,000 metres at Apollo. There are currently twenty-five drill holes in the lab with assay results for most of these holes expected in the near term.

Ari Sussman, Executive Chairman commented: “Drilling at Apollo continues to intercept impressive mineralization which begins at surface, extends over more than 1,200 vertical metres and is still open at depth. The second half of the year is going to be exciting as we are positioning the Company to deliver the next leg of growth.  Firstly, and importantly, the first of two, deep penetrating rigs has just arrived in Colombia and will soon be mobilized to Apollo where it will begin an expansion program of the high-grade Ramp Zone located at the bottom of Apollo. Secondly, exploratory drilling is underway on the series of Apollo look-alike gravity anomalies located within 2 kilometres of Apollo and on trend from the Marmato mine. Finally, our second rig at the San Antonio Project is now turning as we follow up on promising earlier drill results indicating the potential to discover a large porphyry system.”

Details (see Table 1 and Figures 1-3)

• Six drill holes drilled from Pad 22 and Pad 23 intersected high-grade gold, silver, copper and tungsten mineralization at or near surface in intervals ranging between 50 and 400 metres, with results as follows:
  • APC-122: 397.50 metres @ 2.62 g/t gold equivalent from surface and bottoming in high-grade mineralization including:
    • 57.70 metres @ 4.00 g/t gold equivalent from 17.40 metres
    • 40.55 metres @ 4.00 g/t gold equivalent from 293.25 metres
    • 34.80 metres @ 4.13 g/t gold equivalent from 348.20 metres

The intercept in hole APC-122 yielded 1,041 g/t gold equivalent on a gram X metre basis and is the eighteenth gold equivalent accumulation drilled at Apollo at over 1,000 grams x metres.

• • 135.20 metres @ 2.71 g/t gold equivalent from surface and including 43.85 metres @ 3.15 g/t gold equivalent (APC-119 drilled in a northwest direction from Pad 22).
  • 152.10 metres @ 2.06 g/t gold equivalent from surface and including 23.0 metres @ 3.19 g/t gold equivalent (APC-120 drilled to the south from Pad 22).
  • 73.75 metres @ 1.69 g/t gold equivalent from 7.25 metres downhole and including 19.85 metres @ 3.04 g/t gold equivalent (APC-116 drilled to the northwest from Pad 23).
  • 72.85 metres @ 2.01 g/t gold equivalent from 15.0 metres downhole and 20.30 metres @ 2.61 g/t gold equivalent from 113.65 metres downhole (APC-118 drilled in a northeast direction from Pad 23).
  • 68.30 metres @ 1.58 g/t gold equivalent from 42.50 metres and including 23.0 metres @ 3.31 g/t gold equivalent (APC-121 drilled in a northeast direction from Pad 23).
• Over two thirds of the 33-hole infill drill program have now been completed with assays still pending for eight holes. To date, drill intercepts from the shallow program have expanded the volume of the shallow mineralized area by approximately 5 percent. Once the shallow drilling infill program has been completed, the average drill hole spacing will be 35 metres from surface to a vertical depth of 150 metres.

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% interests 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 are to improve the overall grade of the Apollo system by systematically drill testing newly modeled potentially high-grade sub-zones, expand the Apollo system by stepping out along strike to the north and expanding the newly discovered high-grade Ramp Zone along strike and to depth and drill a series of less advanced or newly generated targets including Trap, the Knife and X. Additionally, the Company has launched its largest drilling campaign in history at the San Antonio Project as it hunts for a large bulk-tonnage porphyry system.

Management, insiders, a strategic investor and close family and friends own 44.5% of the outstanding shares of the Company and as a result, are fully aligned with shareholders. The Company is listed on both the NYSE and TSX under the trading symbol “CNL”.
