Koba’s drilling delivers pleasing bouquet with high-grade uranium notes at Berber and Chivas

Special Report: Drilling continues to prove there’s plenty of uranium still to be found at Koba Resources’ Yarramba project in South Australia with high-grade mineralisation intersected at the Berber and Chivas prospect.

Limited initial follow-up drilling extended high-grade mineralisation at Berber over a strike of >700m and discovered high-grade mineralisation at Chivas.

This comes after returning hits such as 1.6m grading 1026 parts per million (ppm) eU3O8 from 91.5m (including 1m at 1413ppm eU3O8 from 91.8m) at Berber, and 1m at 629ppm eU3O8 from 83.1m at Chivas.

What makes the finds even more exciting for Koba Resources (ASX:KOB) is that Berber remains open in all directions while Chivas is completely open and undrilled to east, meaning that mineralisation could grow further with more drilling.

It also demonstrates there’s significant room for growth given the success of very limited drilling.

“Our drilling program continues to show strong potential for resource growth through discovery at the Yarramba uranium project in South Australia, with significant high-grade mineralisation discovered in follow-up drilling at both the Berber and Chivas prospects,” managing director Ben Vallerine said.

He added that discovering high-grade mineralisation in two new areas so soon after starting exploration drilling and confirming considerable mineralisation at the Oban deposit provided the company with strong encouragement to find multiple additional high-grade deposits across the 5000km² of tenure and 250km of palaeochannels.

Yarramba project

The Yarramba project sits within a world-class uranium district in South Australia and is just 17km north of Boss Energy’s (ASX:BOE) 71.6Mlbs Honeymoon operation, which recently started mining with the first drum of yellowcake produced in April 2024, and 120km southeast of the Beverley uranium mine, which has been producing continuously for 20 years.

Yarramba itself has an existing uranium resource at the Oban deposit, though this conforms to the older JORC 2004 standard and will require more work to bring up to the current JORC 2012 standard.

KOB’s initial drilling at Oban returned significant intersections such as 3.9m at 805ppm eU3O8 from 87m and 2.1m at 1069ppm eU3O8 from 86.3m.

There are also plenty more targets to test.

Besides Berber, Chivas and the soon-to-be drilled Mt John, historical broad space drilling has also identified the Yarramba North, Bingelly, Yalkalpo and Bingelly North prospects.

Next steps

KOB is currently mobilising the drill rig to test the highly prospective Mt John prospect, which hosts ~15km of the highly endowed Yarramba Palaeochannel, which also hosts BOE’s Jason deposit and its producing Honeymoon mine.

Inaugural passive seismic surveying is also underway at Mt John to help map the extents of the Yarramba Palaeochannel to help refine drill targets.

Additionally, the company is planning for further follow-up drilling at Berber and Chivas in early 2025.

“Berber remains very sparsely drilled and we believe there is considerable opportunity to delineate high-grade resources,” Vallerine noted.

He added that Chivas is also very exciting as mineralisation remains completely open to the east, so this is now a very high-priority target area for follow-up drilling in early 2025.
