• Adit core sampling imminent to obtain JORC-acceptable samples from high-grade antimony veins and gold-rich alteration zones
• Two diamond rigs advancing 7,000-10,000 metre maiden drilling program to validate and expand historic foreign resource estimate
• Extensive stibnite-bearing vein systems mapped, confirming strong structural continuity and guiding current drilling and JORC resource definition work

Krakatoa Resources Limited (ASX: KTA) is pleased to provide an update on the progress of its maiden drilling and underground sampling programs at the Zopkhito Antimony-Gold Project in Georgia, Eastern Europe. The company is advancing its exploration rapidly, with adit core sampling set to commence this week to obtain JORC-acceptable samples from the high-grade antimony veins and gold-rich alteration zones. Additionally, Krakatoa's 7,000 - 10,000 metre diamond drilling campaign continues to accelerate, with two rigs operating concurrently across multiple high-priority targets between historical adits. The current program is designed to validate and expand the historical foreign resource estimate of 225,000 tonnes at 11.6% Sb (26,000 tonnes contained antimony) and 7.1 million tonnes at 3.7 g/t Au (815,119 ounces gold), moving toward a maiden JORC-compliant Mineral Resource. Detailed underground mapping and sampling have validated multiple continuous stibnite-rich quartz veins, confirming strong structural continuity and directly guiding current drilling and JORC resource definition work. With approximately 90% of global antimony supply controlled by China, Zopkhito provides rare exposure to a critical mineral asset positioned to support EU and US supply chain diversification across energy storage, defence, and advanced material sectors. Ongoing drilling and underground sampling will deliver regular operational updates, with initial batch of core samples expected to be assayed in late Q4 2025.

Krakatoa remains focused on converting and extending the historic foreign resource estimate to a JORC-compliant Mineral Resource. The combination of dual-rig drilling and adit core sampling continues to accelerate field progress, positioning Krakatoa for a steady stream of operational updates and analytical results through late 2025.
