2.2% TREYO Rock Chip Assay at Leatherback, Byro East Project
11 April 2024


WA Byro East Project

  • High-grade rock chip assays up to 2.20% 1TREYO (33% NdPr) (BY23A0067) have been received from the Leatherback L1 mineralised trend. Results significantly surpass previous high of 1.09% TREYO (BY23K0360) collected from the L2 trend.

  • Multiple new assays > 0.5% TREYO further substantiate the Leatherback L1 & L2 mineralised trends as drill targets with possible extension in multiple directions under transported cover.

  • A fifth REE mineralised trend (L5) identified in the NW of the Leatherback Alkaline complex sub parallel to the Leatherback magnetic high producing a visual geophysical horizon to explore along.

  • L1 – L5 surface mineralisation now spanning 2.5km in strike.

  • Micro XRF analysis of selected REE mineralised rock chips identify LREE & HREE mineralisation to primary Monazite and Xenotime respectively.

  • Nickel Laterite sample BY23A0339 collected from a gossanous lateritic sub-crop within a dominantly flat alluvial cover setting returned a grade of 0.54% Nickel (Ni) & 0.78% Chrome (Cr). Sample is located 170m east of single low priority VTEM conductor pick and 1100m north of a cluster of 5, high priority bedrock conductor picks.
