Drilling on track12 Jan 2026 11:49
This is a big moment for Ajax and one that really deserves attention. Drilling has officially started at the Eureka Gold and Copper Project in Jujuy, Argentina, and for context, this is a project with around 400 years of documented copper and gold production that has never been drill tested with modern methods. That alone puts Eureka in a very rare category.
The initial programme is fully funded, fully permitted and relatively tight at around 1,500 metres across roughly 10 diamond drill holes. The targets make a lot of sense technically. Ajax is testing a mix of shallow geochemical and IP anomalies alongside a deeper chargeability feature highlighted by SRK Consulting back in 2014, which could mark the transition into a sulphide-rich part of the system. In simple terms, this is exactly where you would want to be drilling first.
The drilling is happening close to Mina Eureka itself, the historic mine at the heart of the project. Despite centuries of production, no one has ever properly drilled beneath it. On top of that, surface work across the wider project area has already confirmed high-grade copper oxides, including historical samples up to 6.1% copper and plenty above 0.5% copper. Those are not marginal numbers and they strongly support the geological model being tested.
There is also a solid body of historical work that adds colour here. Minera Peñoles and Codelco both identified what appears to be a large copper system, and Mantos Blancos, now part of Anglo American, went as far as underground mapping and bulk sampling, declaring a historical, non-compliant gold resource of around 52,000 ounces. None of this can be treated as a modern resource, but it does explain why Eureka has remained on the radar of serious operators over the years.
Crucially, Ajax is doing this the right way. The programme is funded, focused, and being run with proper environmental, safety, and community standards in place. This isn’t promotional drilling, it’s a first proper test of a project that has all the hallmarks of something much bigger.
With initial assay results expected by the end of Q1 2026, the company has now moved from theory to execution. For shareholders, this is the point where a historically productive but underexplored asset starts to reveal what it can actually deliver.
