14.3% Niobium & 70.3% HREO Assays Returned From Samples Associated With Rare-Element (NYF) Pegmatite


Reach Resources Limited (ASX: RR1 & RR1O) (“Reach” or “the Company”) is pleased to announce further laboratory assay results following the Company’s recent sampling program undertaken at its 100% owned Yinnetharra projects, located in the emerging Gascoyne Mineral Field, Western Australia #. The Rare Earth Elements (REE) results from Wabli Creek follow the recently reported high grade lithium results of up to 2.3% Li2O (ASX Announcement – 15 May 2023) and high‐grade Copper results of up to 33% Cu (ASX Announcement – 18 May 2023), both at the Company’s Morrissey Hill project.


Importantly, the receipt of these high‐grade assays from the sampling program at Wabli Creek of 14.3 % Nb2O5, 6.7% Ta2O5, 3689 ppm TREO with 70.3% HREO (Figure 4) build upon previously reported results at this tenement.

HIGHLIGHTS:

  • Sensational high‐grade results from surface eluvial samples at Wabli Creek, Yinnetharra
    • 14.3 % Nb2O5, 6.7% Ta2O5, 3689 ppm TREO with 70.3% HREO
  • 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
  • Results outlined above follow previously announced high‐grade results from Wabli Creek:‐
    • 6.78 % Nb2O5, 3.71 % Ta2O5, 2.57% TREO with 88% HREO (ASX: RR1 Announcement 13/12/22)
    • 32 % Nb2O5, 12.4% Ta2O5 (ASX: RR1 Announcement 29/11/21)
  • 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


* The result is from grab samples of surface eluvium and may not reflect the average in‐situ grade of the host pegmatite.No drill testing of any of the pegmatites within the Wabli Creek Pegmatite Field has been undertaken. The subsurface dimensions of the pegmatites and the extent and continuity of any mineralisation within them currently remains unknown.

Western Australian METS Companies Awarded AU$1.25 Million in Funding

The Minerals Research Institute of Western Australia (MRIWA) said on Wednesday (October 30) that it is awarding five companies with research funding through its Mining Equipment, Technology and Services (METS) Innovation Program.

The funding totals AU$1.25 million, with Aquirian (ASX:AQN), Total Marine Technology, Big Roller Overland Conveyor Company, Electric Power Conversions Australia and CMG Operations receiving AU$250,000 each.

The WA government said it prioritizes “projects that will directly accelerate the development of companies, products and new markets benefiting the Western Australian economy” for the METS Innovation Program.

Aquirian, the only publicly listed company receiving the grant, will allocate the funding for developing automation for its existing Collar Keeper system. This would allow the driller to stay inside the cab, reducing personnel risk in drilling.
