Krakatoa Resources Ltd identifies extension of pegmatite complex at Dalgaranga Critical Metals project in WA

Krakatoa Resources Ltd (ASX:KTA) has completed resource drilling on its 100% owned Dalgaranga Critical Metals project, approximately 70 kilometers from Mt Magnet in Washington state.

The company drilled 32 reverse circulation (RC) holes over 3,045 meters in May and June, targeting a suite of mineralized pegmatites rich in rubidium, tantalum, cesium, niobium and lithium.

This program has highlighted additional areas of thick pegmatite outside the historic exploration footprint, which remain open to the north and south, while infill drilling has reaffirmed the existing drilling pattern.

Target rubidium

The infill drilling at Dalgaranga has been designed to target rubidium, which is believed to be present in highly anomalous values ​​compared to previous work, and will allow the calculation of a first mineral resource.

Rubidium (as rubidium carbonate) has many industrial uses and generally improves stability and durability while reducing conductance.

It is mainly used in specialized eyewear such as fiber optic cables for telecommunications systems and plays an important role in GPS systems, night vision devices, medical equipment and quantum computing.

Rubidium mineralization is not obviously visible so it is not possible to infer grades at this stage, but thick pegmatite intersections have been consistently encountered at expected depths and the existing geological model has proven accurate.

Around 1,400 samples are on their way to the lab for analysis with results expected in due course.

Extension drilling indicates an open strike

A number of step-out drilling has been added to the program with very promising results, allowing the company to add significant tonnage to the pegmatite model and, importantly, also indicating that the system has not yet been closed.

At this point there is insufficient data to infer the continuity of the pegmatites along the 650 meter strike length, but future drilling plans will seek to test this theory.

Reconnaissance drilling to the south intersected shallow pegmatites with up to 16 meters encountered in the upper 30 meters in one hole.

All samples are in the laboratory for analysis.

“Enhanced potential”

Krakatoa CEO Mark Major said: “The potential of the Dalgaranga project has been bolstered with growing demand and the expectation of further increases in demand and prices for the critical and strategic metals identified in this pegmatite complex.

“The company has recognized the potential of the project and the ongoing drilling has demonstrated this, with extensions of the main pegmatite being identified and remaining open.

“This complements the thick shallow pegmatite already intersected in reconnaissance holes to the south.

“All things considered, the drilling was very successful and we now await the assay results with some excitement. We believe the project has substantial benefits, which could be a great outcome for shareholders.

Next steps

The Dalgaranga zone is considered promising for tantalum, lithium, niobium, tungsten, tin and rubidium. Historic mechanized mining produced tantalum, beryl, tin, and tungsten from a shallow open pit in 2001 and 2002.

Work is underway to model the pegmatites in detail and compile additional data to support an initial mineral resource estimate.

Once the company can define the resource with certainty, it will undertake metallurgical testing to identify the appropriate product suites in the different zones of the pegmatite complex.

Krakatoa believes the current demand for the currently identified specialty metals can make potential mining viable.

The expansion of land ownership in Krakatoa has also brought the company closer to this ambition.
