Krakatoa Resources (ASX:KTA) restarts Zopkhito drilling with a maiden JORC resource in sight

Converting a 26,000-tonne antimony foreign estimate into JORC is the catalyst that re-rates this stock

Krakatoa Resources (ASX:KTA) has kicked off its 2026 surface diamond drilling program at the Zopkhito Antimony-Gold Project in Georgia. The bigger story here is not that drills are turning. It is what those drills are turning for.

Zopkhito sits on a foreign resource estimate of 225Kt at 11.6% antimony for 26,000 contained tonnes, plus 7.1Mt at 3.7g/t for 815,119 ounces of gold. That number is not currently JORC compliant, which means most institutional investors cannot put it in a valuation model. Converting it is what this season is really about.

Antimony has quietly become one of the most strategically sensitive critical minerals on the planet. China controls the bulk of global supply, export restrictions have tightened, and Western buyers are scrambling for non-Chinese tonnes. A 26,000-tonne European antimony resource, if validated, lands in a market that is short of credible options.

The 2026 program is designed to deliver resource definition drilling, metallurgical optimisation and preliminary mining studies. Underground drilling and bulk adit sampling are expected to start in the coming weeks.

Why the JORC conversion is the only number that matters this year

Foreign resource estimates are a legacy of Soviet-era reporting standards. They contain real data but cannot be relied on under ASX rules, which is why Krakatoa has to flag the cautionary statement every time.

The 2026 drilling is targeted at panels where mineralised antimony and gold veins were already intersected through the 27 kilometres of historical adits. That is sensible. Drill where the rock has already shown its hand, then box it into a number that complies with JORC 2012.

If management can deliver a maiden JORC resource that is in the same neighbourhood as the foreign estimate, the stock gets to be valued on a real number rather than a footnote. That is the catalyst worth watching.

Antimony’s geopolitical premium is doing real work here

Antimony is used in defence applications, flame retardants and increasingly in solar glass and grid-scale batteries. China has progressively tightened exports, and prices have moved accordingly. A European-sourced antimony deposit at 11.6% head grade is a genuinely rare asset.

We think the strategic angle is what gives Zopkhito optionality beyond the standard junior explorer playbook. A meaningful JORC antimony resource in Georgia, with a mining licence valid to 2042, is the kind of asset a European processor or defence-aligned offtaker might pay attention to well before first production.

The 815,000-ounce gold credit is not the headline, but at current prices it materially improves project economics if the metallurgy holds up.

Georgia is the unsexy reason this project is fundable

Junior explorers often die on jurisdiction. Krakatoa has chosen a country that ranks #7 globally for ease of doing business and recently granted a two-year extension on the exploration period under the active extraction licence.

That matters because the typical risk discount applied to emerging-market resource projects does not bite as hard here. Georgia has free trade access into the EU through the DCFTA, which is precisely where the antimony demand sits.

The skeptical read is that Krakatoa still only holds an option to acquire up to 80% of the project, not the asset itself. Investors should understand that distinction before assuming the resource sits on the balance sheet.

The Investors Takeaway for Krakatoa Resources

The investment case here is binary in a useful way. Either the 2026 drilling validates the foreign estimate and Krakatoa ends the year with a maiden JORC antimony-gold resource of genuine scale, or it does not. Everything else, including the Georgia narrative and the antimony tailwind, hangs off that single deliverable.

We would want to see first assays land within the next two quarters, alongside clarity on the metallurgical work and bulk sampling results from the adits. Investors can find more in-depth coverage of ASX-listed critical minerals juniors at stocksdownunder.

If Krakatoa delivers the JORC number and the underground program confirms continuity, the project moves from speculative to fundable. That is the rerating path.
