Collective Mining Ltd. has delivered a maiden Mineral Resource for the Apollo deposit at its Guayabales Project in Caldas, Colombia, establishing an initial inventory of 37.0 million tonnes grading 2.17 g/t gold equivalent in the Indicated category and 48.2 million tonnes at 1.83 g/t in the Inferred category.

The estimate incorporates 114,520 meters of diamond drilling across 265 holes based on a database cut-off date of March 31, 2026.

Apollo’s layout includes an open-pit component containing 22.5 million tonnes at 2.06 g/t gold equivalent Indicated for 1.49 million ounces, alongside an Inferred open-pit inventory of 25.9 million tonnes at 0.86 g/t for 0.71 million ounces at a 3.4:1 strip ratio. Underground resources feature a zone above the 1,000-meter elevation holding 13.2 million tonnes at 2.10 g/t Indicated and 16.2 million tonnes at 2.06 g/t Inferred. Below that level, the high-grade Ramp Zone contains 1.29 million tonnes at 4.74 g/t Indicated and 6.04 million tonnes at 5.37 g/t Inferred.

Silver, copper and tungsten contribute approximately 50 percent of the calculated gold-equivalent grade within the Indicated open-pit resource.

"The scale and grade of Apollo's maiden Mineral Resource establish a strong foundation for what we believe will become a major mining project," said Ari Sussman, Executive Chairman. "Importantly, this is the largest new mineral resource stage discovery in Colombia since we discovered Buriticá for Continental Gold more than a decade ago."

The company excluded roughly 40,000 meters of drilling completed since the database cut-off from the maiden estimate. Those post-cut-off holes have intersected extensions to mineralization at multiple elevations. Thirteen rigs currently operate across Guayabales to test further extensions and increase resource confidence.

"We see a favorable backdrop for advancing Apollo, both in Colombia and across the commodities represented in the deposit," Sussman added. "That outlook supports our decision to accelerate environmental baseline work, engineering, and permitting studies alongside exploration, with the aim of submitting an environmental license application in the second half of 2027."

Collective Mining targets the start of construction on an underground exploration adit at Guayabales in the fourth quarter of 2026. An updated Apollo Mineral Resource incorporating post-cut-off drilling is scheduled for release in the first quarter of 2028.
