Krakatoa Resources Limited (ASX: KTA) has completed a successful resource drilling campaign at its 100% owned Dalgaranga critical metals project located approximately 70km from Mt Magnet, Western Australia.
“The potential of the Dalgaranga project has been strengthened with rising demand and prediction of further demand and price increases of critical and strategic metals identified within this pegmatite complex,” CEO, Mark Major, said.
“The company recognised the projects potential, and the current drilling has highlighted this with extensions of the main pegmatite being identified and remaining open. This compliments the thick shallow pegmatite already intersected in the reconnaissance holes to the south.
“All things considered the drilling has been very successful and we now await the assay results with some excitement. We believe the project has substantial upside which could be a great result for the shareholders.”
The company drilled 32 RC drillholes for a total of 3045m during May and June 2022. The programme targeted a suite of mineralized pegmatites which are enriched in rubidium, tantalum, caesium, niobium and lithium and was designed to infill existing drilling to a nominal 40 x 40m spacing to allow calculation of a maiden mineral resource.
Rubidium was the primary target of the drilling with previous work having returned highly anomalous values over a large areal extent. The rubidium mineralisation is not obviously visible therefore it is not possible to infer grades at this stage, however thick intersections of pegmatite were regularly encountered at the expected depths and the existing geology model was shown to be accurate.
Approximately 1400 samples have been shipped to ALS for assaying, with results expected in due course. Whilst the drilling was mainly infill, a number of extensional holes were added to the program with very promising results.
Drillhole DAL033 encountered 32m of pegmatite from 33-65m downhole, which extended the known boundary of the central pegmatite north by 65m. Similarly, drillhole DAL004 encountered 12m of pegmatite from 46m downhole and extends the central pegmatite south by 30m. These extensional drillholes allow us to add significant tonnage to the pegmatite model and importantly they also indicate that the system has not been closed out yet.
Farther south on the tenure and beyond any existing drilling, three exploration holes (DAL027 – DAL029) were drilled to test an area where geological mapping had indicated pegmatite at surface.
Mr Major said the results from these holes were particularly pleasing, with DAL029 returning 16m of pegmatite from three lenses in the first 30m of the drillhole and additional pegmatite below 74m.
DAL029 is located 650m south of our existing wireframes and 200m south of the previous southernmost hole. At this stage there is insufficient data to infer continuity of the pegmatites along the full 650m of strike extent, however future drilling plans will seek to test this theory.
All drillhole data including the pegmatite intersections are detailed in Table 1. The reference to pegmatite does not necessarily reflect the presence the critical metals or a mineralised zone. It only represents the geological lithology in which the mineralisation has been recorded and evidenced from by previous exploration
The first interval of 4.0 metres starting at 32 metres and a second wider intersection of 22 metres from 70m downhole.
DAL018 encountered 44 metres of pegmatite from 33 metres downhole. Within these pegmatite zones several zones of associated critical metals mineralisation are thought to be present. No grade or associated mineralisation is determination is given or assumed and will be forthcoming once the laboratory analysis is complete.
