YINNETHARA

Morrissey Hill
Lithium


The Morrissey Hill Project is strategically located between large Gascoyne Lithium Projects (Delta Lithium & Minerals 260) boasting high grade results from outcropping pegmatites along strike from Delta Lithium.

​
The Maiden drilling program on initial lithium targets commenced in September 2023 with  results due mid-October 2023.
 

Mapping at Morrissey Hill has now identified more than 50 previously unrecognised pegmatites with a combined cumulative strike length in excess of 10km.
 

Highlights

​

  • Lithium mineralisation confirmed with rock chip assays up to 2.3% Li₂O (lithium oxide); 4295ppm Cs (caesium) and 705.8ppm Ta₂O₅ (tantalum oxide). *
     

  • Phase 1 drilling intersected multiple thick, stacked pegmatites up to 30m thick at the Bonzer Prospect to depths of ~400m (down hole), Morrissey Hill.**
     

  • At least one of the larger pegmatites intersected at depth appears to be “blind”.
     

  • Phase 1 has drill tested just one of several prospective pegmatite zones in the right geological setting.

Wabli Creek
Niobium

Highlights
​

  • Latest surface eluvial and rock samples (28June 2023) taken at the Wabli Creek rare element (NYF) pegmatite field returned high grade niobium of 10.3% Nb₂O₅ (23RRRK243) and 2.6% Nb₂O₅ (23RRRK244).
     

  • Samples from latest program (28/6/2023) taken up to 400m east of the previously mapped (1/6/2023) north-west pegmatite trend spanning ~1.5km, which returned results up to 14.3% Nb₂O₅, 6.7% Ta₂O₅, 3689ppm TREO with 70.3% HREO
     

  • 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
     

  • Latest results indicate a potential stacked pegmatite sequence and/or a new niobium/REE mineralisation source. 

​​

  • 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

Camel Hill
REE

Highlights

​

  • New tenement E09/2388 (Camel Hill) has historical rock-chip samples with total rare earth oxide (TREO) results of up to 1,357 ppm.

​

  • A ~3.5-km long REE soil anomaly (>500 ppm REE) untested by drilling.

​

  • Recorded REE anomalies correspond with thorium radiometric highs.

​

  • The new acquisition combined with tenement E09/2377 increases the land holding for this project area to168 sq km.
