What Koba Resources Limited does

Koba Resources Limited (ASX: KOB) is an Australian critical minerals exploration company that is pre-revenue and focused on advancing a diversified portfolio of early-stage projects across three commodities: uranium, tin-tungsten, and cobalt-copper. The company was incorporated and listed on the ASX in May 2022 and is headquartered in Subiaco, Western Australia, with operational assets in South Australia, Queensland (Australia), and Idaho (United States). Its flagship is the Yarramba Uranium Project in South Australia's Frome Embayment — a world-class uranium district where the company holds an 80% interest over more than 4,900km² and more than 250km of prospective palaeochannels; the project includes the Oban Uranium Deposit with a JORC 2004 Resource Estimate of 8.2Mt @ 260ppm U3O8 for 4.6Mlbs. In October 2025 Koba added the Stannary Hills and Mt Garnet Tin-Tungsten Projects in Queensland's Herberton Tin Field, and earlier it acquired the Blackpine and Colson Cobalt-Copper Projects in the Idaho Cobalt Belt.

Koba employs conventional mineral exploration methods — reverse-circulation and diamond drilling, soil and rock-chip geochemistry, induced polarisation (IP) geophysics, and gamma logging — to delineate mineralised targets. The company's go-to-market model is investor-driven and event-led: as a pre-revenue explorer, it relies on ASX continuous disclosure, equity placements (most recently a A$4.35M raise in October 2025), investor conferences, and media coverage to communicate progress and attract capital. The commercial pathway is to advance projects to resource definition and then monetise through farm-out, joint venture, acquisition, or production — with potential partnership discussions already flagged with Boss Energy at Yarramba and infrastructure-sharing opportunities implicit in the proximity to Jervois Global's Idaho Cobalt Operation. There is no current product revenue, no offtake agreements, and no production.

The company is led by Managing Director and CEO Benjamin Vallerine (ex-Black Range Minerals, Caspin Resources, Renegade Exploration) and Non-Executive Chairman Michael Haynes (former Managing Director of Black Range Minerals for over 10 years, ex-BHP Minerals and Billiton), supported by Non-Executive Director Scott Funston (Chartered Accountant, ex-CFO of Avanco Resources acquired by Oz Minerals) and Company Secretary Ian Cunningham (ex-Adamus Resources and Deloitte). Funding history is consistent with an early-stage ASX-listed explorer, and the strategic positioning combines district-scale land packages with adjacency to operating critical minerals infrastructure.

Revenue model

1. Mineral Exploration (Pre-Revenue): Koba Resources is a pre-revenue exploration company. It has no current production or revenue. The company is advancing projects toward resource definition and ultimately production or offtake/partnership with third parties. Revenue would ultimately derive from sale of mineral products (uranium, tin, tungsten, cobalt) or via project-level transactions (farm-outs, acquisitions).

Core offering

Koba Resources Limited is a pre-revenue Australian mineral exploration company that acquires, advances, and seeks to develop critical minerals projects across uranium, tin-tungsten, and cobalt-copper. The company funds exploration through ASX equity raises, advances projects using conventional drilling, geochemical, and geophysical methods, and targets monetisation through eventual production, offtake agreements, farm-out arrangements, or acquisition by larger producers.

Product overview

Koba Resources Limited is an Australian critical minerals exploration company with a diversified portfolio of exploration projects spanning uranium, tin-tungsten, and cobalt-copper. The company's primary assets include the Yarramba Uranium Project in South Australia (with the advanced Oban Deposit), the Stannary Hills and Mt Garnet Tin-Tungsten Projects in Queensland's Herberton Tin Field, and the Blackpine and Colson Cobalt-Copper Projects in the Idaho Cobalt Belt, USA. The company operates as a single-portfolio exploration business focused on advancing these critical minerals projects rather than offering software products or platforms.

Products and services

• Yarramba Uranium Project Uranium exploration project located in South Australia's Frome Embayment, covering over 4,900 km² of tenure. Includes the advanced Oban Uranium Deposit with a JORC 2004 Resource Estimate of 8.2Mt @ 260ppm U₃O₈ for 4.6Mlbs U₃O₈. Targets sand-hosted uranium mineralisation amenable to in-situ recovery (ISR) extraction in a world-class uranium district adjacent to Boss Energy's Honeymoon and the Beverley operation.
• Stannary Hills Tin-Tungsten Project Tin-tungsten exploration project covering 79km² in North Queensland within the Herberton Tin Field. Includes over 100 historical tin mines with mineralisation along the Kitchener Trend and Atlanta Trend, with significant high-grade and bulk-tonnage tin potential.
• Mt Garnet Tin-Tungsten Project Tin-tungsten exploration project covering approximately 353km² in North Queensland. Hosts over 300 historical tin mines including the Gilmore Tin Mine and features high-grade tin and tungsten mineralisation at the Boulder Prospect and Stannex Prospect.
• Blackpine Cobalt-Copper Project Cobalt-copper exploration project in the Idaho Cobalt Belt, USA. Spans 517 hectares covering approximately 6km of prospective strike with high-grade cobalt, copper, and gold mineralisation across ten major prospects including the historic Blackpine Mine. Uses IP geophysics combined with soil geochemistry to delineate sulphide targets.
• Colson Cobalt-Copper Project Cobalt-copper exploration project in the Idaho Cobalt Belt, USA. Contains the historic Salmon Canyon Mine with strong IP anomalism and coincident cobalt and copper soil geochemistry across multiple high-priority drill-ready targets, covering 1,550 hectares.

Partnerships

Two partnerships are on record, tiered potential / flagged and adjacent / regional.

• Boss Energy Limitedpotential / flaggedStrategic or Co-development Partner · 2 March 2026Koba Resources flagged a potential partnership with Boss Energy at the Yarramba Uranium Project. Boss Energy operates the adjacent Honeymoon Uranium Operation (71.6Mlbs @ 620ppm U₃O₈), located 17km south of Koba's Yarramba Project. A potential collaboration could involve shared infrastructure, toll treatment, or joint exploration within the Yarramba paleochannel system.
• Jervois Global Limitedadjacent / regionalOthersJervois Global is developing the Idaho Cobalt Operation at the Ram Deposit within the Idaho Cobalt Belt, approximately 15km northwest of Koba's Blackpine Project. The Blackbird District (including Jervois' operations) has estimated endowment of 17Mt @ 0.74% Co, 1.4% Cu, 1.0 g/t Au. Koba's proximity to Jervois' developing infrastructure may provide future toll-milling or shared infrastructure opportunities.
