Koba Resources Limited (ASX: KOB) is an emerging Australian exploration company advancing a stronge portfolio of high-potential critical minerals projects. The company is actively progressing two high-grade tin-tungsten projects in Queensland the Stannary Hills & Mt Garnet Projects alongside the large-scale Yarramba Uranium Project in South Australia – one of the world’s premier uranium jurisdictions. Strategically positioned in proven mining regions, Koba combines district-scale exploration upside with a clear focus on minerals vital to clean energy and advanced technology, delivering compelling value for shareholders in Australia’s dynamic resources sector.
Our Projects
Stannary Hills and Mt Garnet Tin-Tungsten Projects – Queensland
The Stannary and Mt Garnett projects provide exposure to an increasing tin price back by strong market fundamentals due to:
- Supply-side disruptions in three of the worlds leading tin producing counties in Myanmar, Indonesia and the DRC
- Increasing demand as tine benefits from a strong role in new technologies
- A global tin market deficit of ~14,000 tonnes in Q1 2025 which is forecast to widen through to 2030
Part of the Herberton Tin Field, known for its rich tin mining history
- With over 2,400 historical mines it is the second largest tin producing district in Australia
Location of the historic mines within the Herberton Tin Field and the boundaries of Koba’s projects in North Queensland
Extensive mineralisation across the Project
- Significant high-grade mineralisation
- Strong potential for larger, lower-grade bulk tonnage tin
Considerable opportunities for discovery by drilling below, between and along strike from high-grade historical mines that have seen limited modern exploration. Including the Kitchener trend where 7 -high-grade mines produced ~ 120,000 tonnes of ore at ~2.3% Sn over 1.3 of strike
A 1.3km section of the Kitchener Trend, comprises 7 high-grade historic mines, significant unmined mineralisation remains
open at depth and along strike
Yarramba Uranium Project – South Australia
The Yarramba Project is located 17km north of the Honeymoon Uranium Operation – resources total 71.6Mlbs of U₃O₈ at 620ppm U₃O₈; and 120km southeast of the Beverley Uranium Operation – with production of >40Mlbs of U₃O₈ during 20 years of continuous operation and where defined resources comprise 165Mlbs @ 2,766ppm U₃O₈.
- During 2024-25 Koba completed 141 holes for ~14,600m and made 4 high-grade discoveries including:
- Berber Prospect – 1.6m @ 1,026ppm eU₃O₈
- Delord Prospect – 0.5m @ 1,045ppm eU₃O₈
- Chivas Prospect – 0.5m @ 1,028ppm eU₃O₈
- Everest Prospect – 0.4m @ 1,001ppm eU₃O₈
- These high-grade discoveries confirm the significant potential at the Yarramba Project, with over 250km of mineralised palaeochannels to explore across approximately 5,000km² of highly-prospective tenure. Considerable potential remains for further discoveries.
