Dakota Minerals - Final Results: Phase One Drilling at Lynas Find Project

Dakota Minerals has posted final results from phase 1 drilling at the Lynas Find lithium project in the Pilgangoora region of WA, with preparations for the phase 2 program under way, with the aim of defining a maiden resource. New high grade results included 20m @ 2.61% and 17m @ 1.72% Li2O, with the overall weighted average grade from Central Pegmatite of 1.73% Li2O. Lynas Find appears to be a high grade sector of the Pilgangoora district, currently the 2nd largest hard rock deposit globally.


Highlights:

  • inal drilling analyses provide further confirmation of high grades at Lynas Find, including 20m @ 2.61% Li2O
  • Overall weighted average grade of all mineralised intersections at Lynas Find Central Pegmatite 1.73% Li2O
  • Mineralisation still open along strike and down-dip
  • Anomalous mineralisation at >1% Li2O noted in drilling of pegmatites along strike
  • Rock-chipping from other, newly discovered pegmatites in the vicinity yields grades of up to 3.98% Li2O, as Lynas Find known area of mineralisation continues to grow
  • Follow-up drilling expected to commence late May, aiming to define a maiden resource

Dakota Minerals Limited (“Dakota”, “DKO”, or “Company”) is pleased to announce the final results from its phase one drilling programme at the Lynas Find Lithium Project, in the Pilgangoora region of Western Australia. Further high grade resultsinclude 20m @ 2.61% and 17m @ 1.72% Li2O, giving an overall weighted average grade from mineralised drill intercepts at Lynas Find Central Pegmatite of 1.73% Li2O. Rockchipping of other, newly discovered pegmatites in the vicinity yielded grades of up to 3.98% Li2O, indicating a possible structural repeat of Lynas Find Central to the south.

Dakota Minerals Managing Director David Frances commented: “Preparations for the phase two drill programme are already well under way, with the aim of defining a maiden resource at Lynas Find, which appears to be a high grade sector of the Pilgangoora Lithium District, and is currently the second largest known hard rock lithium deposit in the world and growing rapidly.”

Lynas Find Lithium Project: Drilling Programme Details

From the maiden reverse circulation (RC) drilling campaign at Dakota’s Lynas Find Lithium Project, all 26 holes have now been analysed. The drilling was mainly focused on initial testing of the Lynas Find Central pegmatite, with some reconnaissance holes also drilled in the north-east and western extensions. Drilling totalled 1,670m, less than initially planned, due to a lower angle of dip of mineralisation than expected. This is considered to be a positive result, as it lowers exploration cost, and improves the economics of any potential open pit mining scenario. A total of 877 samples, including QA/QC, were dispatched to the lab, all of which have been reported. All of the 21 holes drilled at Lynas Find contained lithium mineralisation, with the overall weighted average grade of the significant intercepts being 1.73% Li2O. The latest results included further high grade intercepts, including 20m @ 2.61 % Li2O (Table 1). The overall results are indicative of a higher grade deposit in Dakota’s Lynas Find Project compared to the regional average in the Pilgangoora Lithium District. High grade mineralisation is still open along strike and down dip, and will be targeted in the next round of drilling. Five holes were also drilled at exploration targets to the north-east and south-west of Lynas Find Central Pegmatite, two of which intersected lithium anomalism above 0.4% Li2O. Further work at Lynas Find will include drilling to expand and define the known area of lithium mineralisation, and testing interpreted potential dilational zone “repeats” to the south of the main Lynas Find zone - expected to commence at the end of May. Preparations for the next round of drilling have commenced.

Lynas Find Lithium Project: Rock-chip Sampling Details

Mapping and sampling of the area surrounding the main Lynas Find Central pegmatite continued in April. Twelve rock-chip samples were taken from new pegmatites mapped to the south of Lynas Find Central, which yielded grades of up to 3.98% Li2O. It is thought that these areas represent structural “repeats” of the dilational zone at the main Lynas Find Central pegmatite, and are therefore priority targets for exploration drilling in the coming months.

Lynas Find Lithium Project

Dakota’s Lynas Find lithium project, to which Dakota has 100% rights, is located on and in the vicinity of an extensive lithium-tantalum bearing pegmatitic dyke swarm. Peer activity in the immediate area known as Pilgangoora, includes Pilbara Minerals Limited (ASX:PLS) and Altura Mining Limited (ASX:AJM), which have both discovered significant lithium and tantalum resources in recent times. Pilbara Minerals has identified a total Indicated and Inferred resource of 80.2Mt @ 1.26% Li2O and 32.9Mt @ 0.022% Ta2O5. On a neighbouring property, Altura Mining has identified an Indicated and Inferred resource of 35.7Mt @ 1.05% Li2O. Following recent exploration activity, the Pilgangoora area has been confirmed to contain one of the world’s largest hardrock lithium deposits, mostly in the form of the mineral spodumene.
