Krakatoa Resources commences underground drilling at Zopkhito

• Underground core sampling drilling underway for second season
• Drilling targeting known mineralised veins
• Program focused on resource definition drilling and metallurgical optimisation
• Exploration program designed to convert current foreign resource estimate into a JORC MRE

Krakatoa Resources (ASX:KTA) has commenced its second field season at the Zopkhito antimony-gold project, located in Georgia.

The program includes a major focus on converting the current foreign resource estimate into a JORC mineral resource estimate (MRE).

Zopkhito contains a foreign resource estimate of 225,000 tonnes at 11.6% stibnite (antimony) for a contained 26,000 tonnes of antimony and 7.1 million tonnes (Mt) 3.7  grams per tonne (g/t) for 815,119 ounce of gold.

CEO, Mark Major, said the project benefits from extensive historical exploration, including approximately 27km of underground exploration adits, over 15,000 historical channel and geochemical samples and prior LiDAR and IP geophysical surveys.

“It is exciting for the company to have commenced the 2026 field season at Zopkhito, with access and site preparation completed,” Mr Major said.

“This work program is designed to support the delivery of a maiden JORC-compliant Mineral Resource Estimate and advance early mine development studies.

“The 2025 drilling program validated the high-grade nature of the antimony and gold mineralisation, as well as the extension potential at Zopkhito, and we believe the 2026 program will build on the high-grade results.

“With antimony emerging as a strategically critical mineral, Zopkhito has the potential to become a rare and significant European source of antimony, and we are looking forward to a very busy year ahead for Krakatoa.”

In 2025, Krakatoa’s drill testing program confirmed both high grade mineralisation within the historical adits and the presence of an extended gold alteration system, in addition to the high-grade quartz-antimony vein development. Drilling successfully intersected mineralisation across multiple target zones, providing the Company with strong geological validation of the historical model.

The results from 2025, combined with the historical underground development, including 27km of underground workings and an exploration database with more than 15,000 historical samples, provide Krakatoa with a significant advantage by utilising previous work to support drill targeting and resource definition.

The company is also planning to undertake additional metallurgical optimisation test work and preliminary mining studies as part of its broader development strategy for Zopkhito.

Additionally, Krakatoa anticipates commencing adit bulk sampling programs in the near term.

Environmental baseline studies and permitting activities continue concurrently to provide further support for future project advancement.
