What Krakatoa Resources does

Krakatoa Resources Limited (ASX: KTA) is an Australian public mineral exploration company headquartered in Perth, Western Australia, with an operational office in Tbilisi, Georgia. The company is pre-revenue and focused on acquiring, exploring, and developing critical and precious metals projects. Its portfolio comprises six assets: the flagship Zopkhito Antimony-Gold Project in Georgia (option to acquire up to 80%), the Mt Clere Rare Earth Project in Western Australia (100%), the King Tamba Speciality Metals Project in Western Australia (100%) targeting lithium, tantalum, niobium, rubidium, and tin, and three 100%-owned gold projects in New South Wales — Belgravia Porphyry, Turon Gold, and Rand Gold. Krakatoa's Zopkhito asset holds a foreign mineral resource estimate of 225Kt at 11.6% Sb (26,000+ tonnes contained antimony) and 7.1Mt at 3.7 g/t Au (800,000+ ounces of gold) under Soviet GKZ classification, positioning it among the highest-grade antimony deposits globally.

The company's core technology stack centres on conventional mineral exploration methods — diamond drilling, IP/AMT geophysical surveys, LiDAR surveys, 3D wireframe vein modelling, and metallurgical testwork. Flotation testwork at Zopkhito has demonstrated a single selective stibnite route producing a 56% Sb concentrate at 87% recovery, with rougher recovery exceeding 90% on high-grade samples. Mt Clere's Tower deposit delivered a maiden JORC 2012 resource of 101MT at 840ppm TREO within seven months of discovery, with 40% classified as Indicated.

Krakatoa has no current revenue stream and its business model is oriented toward advancing exploration-stage assets to a stage where they can attract strategic partners, off-takers, or acquirers. Future revenue is expected from mining operations extracting and selling antimony, gold, rare earth elements, and other critical and precious metals, with Zopkhito positioned as a potential European source of antimony. The company is led by Executive Chairman Colin Locke (30+ years in mining and financial services) and CEO Mark Major (25+ years of international mineral exploration, with prior senior roles at Barrick, BHP, Glencore, Rio Tinto, and WMC), supported by two non-executive directors. A A$3.1 million placement was completed in December 2025 to fund ongoing exploration.

Core offering

Krakatoa Resources is a publicly listed (ASX: KTA) mineral exploration and development company focused on acquiring, exploring, and advancing high-value critical and precious metals projects. Its flagship asset is the Zopkhito high-grade antimony and gold project in Georgia, supported by a portfolio of Australian projects targeting rare earth elements, lithium, rubidium, tantalum, niobium, tin, and gold. The company is currently pre-revenue and intends to become a prominent producer of critical and precious metals through future mining operations.

Product overview

Krakatoa Resources Limited is a diversified mineral exploration company with a portfolio of six advanced and early-stage resource projects. The flagship asset is the Zopkhito Antimony-Gold Project in Georgia (option to acquire up to 80%), one of the highest-grade antimony deposits globally. The company operates three Australian projects: the Mt Clere REE Project (100%, Western Australia) with the Tower clay-hosted rare earth resource, the King Tamba Speciality Metals Project (100%, Western Australia) targeting lithium, tantalum, rubidium, niobium and tin, and three gold projects in NSW — Belgravia Porphyry (Au-Cu), Turon Gold, and Rand Gold. The projects collectively target critical metals (antimony, rare earths, lithium) and precious metals (gold) essential for energy transition and technology applications.

Products and services

• Zopkhito Antimony-Gold Project
• Mt Clere Rare Earth Project Rare earth elements and heavy mineral sands project located approximately 200km northwest of Meekatharra in Western Australia, covering 1,060 km². The project contains the Tower REE Resource with a maiden JORC 2012 mineral resource estimate of 101MT @ 840ppm TREO, of which 40% is classified as Indicated. Intended for future supply of rare earth concentrates to downstream REE processors.
• King Tamba Speciality Metals Project Critical metals project located 80km northwest of Mount Magnet in Western Australia, with mineralisation including lithium, tantalum, niobium, rubidium, and tin. The project includes a JORC mineral resource of 5MT @ 0.14% rubidium oxide and 0.05% lithium oxide credits. Intended for future supply of speciality critical metals to industrial buyers.
• Belgravia Porphyry Project
• Turon Gold Project Gold exploration project covering 120 km² in the East Lachlan Fold Belt, NSW, Australia. The project is positioned 50km east of the Belgravia project and 60km northeast of Newcrest Mining's Cadia Valley Mine, and is prospective for high-grade slate belt orogenic gold. Owned 100% by Krakatoa Resources.
• Rand Gold Project Gold project covering 580 km² in the Central Lachlan Fold Belt, NSW, Australia, owned 100% by Krakatoa Resources. The project captures the historical Bulgandry Goldfield, with historical mines producing gold at grades up to 265 g/t, and covers a 40km structural corridor prospective for further gold discoveries.

Direct peers

• Perpetua Resources: US-listed developer of the Stibnite gold-antimony project in Idaho. A direct antimony-gold peer with an advanced resource and active engagement with US strategic funding for domestic antimony supply.
• Arafura Resources: ASX-listed developer of the Nolans rare earth project in the Northern Territory. Comparable as an Australian clay/host-rock REE developer at a similar pre-construction stage with NdPr-focused economics.
• Larvotto Resources: ASX-listed junior explorer advancing the Hillgrove antimony-gold project in NSW. Closest Australian analogue to Krakatoa's Zopkhito, with a similar antimony-gold critical minerals thesis at a comparable stage of development.
• Trigg Minerals: ASX-listed antimony-focused explorer with Australian critical minerals projects. Directly comparable as a small-cap antimony pure-play positioned around strategic supply themes.
• Variscan Mines: ASX-listed junior with European (Spanish) base and critical metals exposure, including zinc and antimony interests. Comparable as a small-cap European-jurisdiction critical minerals developer.
• King River Resources: ASX-listed explorer advancing both rare earth and antimony critical minerals projects in Australia. Overlaps with Krakatoa's combined REE/antimony critical minerals strategy and similar early-to-mid-stage profile.
• Mandalay Resources: TSX-listed producer operating the Costerfield antimony-gold mine in Victoria, Australia. The only current producing antimony-gold operation at scale, providing a benchmark for project economics and processing flowsheets.

Emerging players

• Northern Minerals: ASX-listed heavy rare earth explorer/developer at Browns Range in Western Australia. Comparable as a small-cap Australian REE developer targeting dysprosium and terbium rather than light REE.

Broad incumbents

• Australian Strategic Materials: ASX-listed critical minerals producer with rare earth, zirconium and hafnium operations including the Dubbo project. Broad incumbent in the Australian critical minerals space with relevant downstream and offtake experience.
• Lynas Rare Earths: ASX-listed world's largest non-China producer of separated rare earths from Mt Weld. Relevant as a benchmark for REE project economics, processing flowsheets and offtake dynamics that will affect Mt Clere's future valuation.
