NIOBIUM

Wabli Creek

Pegmatites at Wabli Creek were evaluated cursorily by Great Mines Ltd, Kookynie Resources NL and Nickel Mines Ltd whilst targeting calcrete hosted uranium deposits between 1974 and 1983. Two mineralised pegmatites have been the focus of exploration to date at Wabli. The No1 vein has been mapped over 10m in a pit and has potential of extending further underneath soil cover. Reconnaissance assays indicate significant levels of critical element like Nb and Ta.

Highlights

​​

  • Sensational high‐grade results from surface eluvial samples at Wabli Creek, Yinnetharra

    • 14.3 % Nb2O5​

    • 6.7% Ta2O5

    • 3689 ppm TREO

    • 70.3% HREO

​

  • HREO results 2 :

    • 7226 ppm Yttrium oxide

    • 3430 ppm Dysprosium oxide

    • 4880 ppm Ytterbium oxide

    • 2760 ppm Erbium oxide

    • 450 ppm Terbium oxide​

​

  • Results outlined above follow previously announced high‐grade results from Wabli Creek:

    • 6.78 % Nb2O5, 3.71 % Ta2O5, 2.57% TREO with 88% HREO​

    • 32 % Nb2O5, 12.4% Ta2O5

​

  • The Wabli Creek Niobium and Total Rare Earth Oxides (TREO) target zone has a potential strike length of up to 1.5km.

​

  • Significantly, all three of the Company’s granted tenements have returned highly anomalous TREO results >500ppm to a maximum of 25,652 ppm or 2.57% TREO.

​

  • Independent geological experts RSC have advised that the consistent high‐grade niobium and HREO is associated with a ~2.5km long rare element pegmatite swarm identified from historical records at Wabli Creek

​

  • Importantly the mineralisation likely extends under cover (Jacobson et al, 2007)  Source of high‐grade niobium and heavy rare earth oxide (HREO) results confirmed as a rare element pegmatite swarm with niobium, yttrium, fluorine (NYF) geochemical signature

​

  • Rare element (NYF) pegmatites are characterised by their unusual enrichment of niobium and heavy rare earth elements (HREE), in contrast to clay hosted or carbonatite deposits which predominantly contain light rare earth elements (LREE)

​

  • Confirmation of a rare element pegmatite system increases the likelihood of identifying additional high‐grade niobium and HREE which are listed as critical minerals by governments worldwide

​

  • Historical records show that one tonne of eluvial samarskite was scraped from one of the pegmatites within the Wabli Creek pegmatite swarm in the 1980’s (no drilling has been undertaken on the tenement). Samarskite is a niobium, yttrium and HREE dominant mineral, further suggesting that this pegmatite swarm could provide a source of high‐grade niobium, yttrium and other HREE such as Dysprosium and Terbium  

​

  • The RR1 team has mapped the rare element (NYF) pegmatite swarm over 1.5km (Figure 1 & 2)  

​

  • This type of mineralisation is rare and presents a unique exploration opportunity for RR1
