COLLECTIVE MINING ANNOUNCES INCLUSION IN THE GDXJ INDEX AND RELOCATION OF HEADQUARTERS TO THE U.S.; BOLSTERING CONNECTIVITY TO OPERATIONS IN COLOMBIA

Collective Mining Ltd. will be added to the Junior Gold Miners Index (the GDXJ) effective at market close on March 20, 2026, pursuant to the index's most recent review and rebalance. Collective also has relocated its executive headquarters from Toronto, Ont., to Miami, Fla. The company's jurisdiction of incorporation will remain in Canada, and its dual listings on the NYSE American and the Toronto Stock Exchange remain unchanged.

Ari Sussman, executive chairman, commented: "Inclusion in the GDXJ marks an important milestone for the company, as it reflects our continued progress in developing a world-class mineral district in Colombia, and reinforces the compelling investment case for Collective. The relocation of the company's executive headquarters to Miami is another important step in our evolution. Miami has rapidly emerged as a leading global financial centre, with a strong institutional capital markets presence and strategic connectivity to Colombia and Latin America. We believe this move will support our long-term growth strategy by increasing investor visibility, broadening our shareholder base and unlocking additional stock market index eligibility."

Miami's geographical location and connectivity to Colombia were central to this decision. Several daily direct flights place management in closer proximity to the company's operations. This move is expected to support more efficient coordination with Collective's internal teams, suppliers, contractors and consultants at a pivotal time, as the company continues to execute on its 2026 exploration program and further advances the derisking and development of its flagship Guayabales project.

The United States represents the deepest and most liquid market for resource equities, and the company notes that an executive office in the United States may enhance Collective Mining's future eligibility for inclusion in certain U.S. equity indices, which are tracked by significant passive and rules-based investment strategies.

About Collective Mining Ltd.

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's two projects are located directly within an established mining camp with 10 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, drill test the new hangingwall vein zone and drill a series of greenfield generated targets on the property.

Additionally, the company is drilling its optioned San Antonio project (can earn up to 100-per-cent interest) as it hunts for new discoveries and looks to aggressively extend to the south the recently discovered high-grade silver system made at the Pound target. The San Antonio project is located between two to five kilometres 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 per cent 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 Toronto Stock Exchange under the trading symbol CNL.
