Rare Earth Trends Emerging at Byro East Project
31 January 2024



Highlights

WA Byro East Project

  • 12 Priority Assays targeting Rare Earth Element (REE) mineralisation have been received with grades up to 0.79% ¹TREYO in rock chip sample BY23A0144 located at the Leatherback Carbonatite Alkaline Complex.

  • Four REE mineralised trends are emerging at the Leatherback Alkaline Complex with possible extensions in multiple directions under transported cover.

  • These REE mineralised trends are coincident with the Leatherback magnetic and gravity highs, interpreted to represent the geophysical extent of Leatherback Alkaline Silicate-Carbonatite Complex over 3.5km in strike.

  • A total of 375 rock chip samples were collected across the central four Byro East tenements (>600km2 ) during the months of October to December 2023. Rock chips aimed to assess 21 of 70 REE-Ba-Sr-Nb-Ca-Ni-Cr-Mg geochemical soil anomalies with 26 samples taken from areas prospective for magmatic Ni-Cu-PGE mineralisation.

  • Selection of samples for both REE and magmatic Ni-Cu-PGE styles of mineralisation were submitted for micro XRF analysis to determine element distribution and mineralogy.

  • Remaining rock chip assays and micro XRF results due mid-February.
