High Grade REE and Niobium Confirmed at Lyons

Lanthanein Resources Ltd (ASX: LNR) (Lanthanein or the Company) is pleased to announce assay results from the recent drilling completed at the Lyons Rare Earths Project in Western Australia (Lyons Project). The drill program targeted high-grade rare earth mineralisation discovered at the outcropping ironstones at Lyons 11, 12, 13 and 27 (Figures 6 and 7).

• Over 1km strike length of economic TREO mineralisation intersected and remains open
• Extremely high Neodymium and Praseodymium grades make up to 55% of Total Rare Earth Oxides (TREO), more than 3 times the world average¹
• Significant Niobium intersections on margins of Lyons Magnetic Intrusive Complex, related to carbonatites under cover to be drill tested in Q1, 2023
• Widths of main ironstone REE mineralisation intersected at Lyons prospects are 1 – 5m thick, analogous to Hastings Technology Metals main REE deposits Simons Find, Frasers and Bald Hill ~2.5km away¹. Significant intercepts include;
  • LYRC047: 5m at 0.69% TREO from 20m, including 2m at 1.06% TREO (41% NdPr:TREO) from 21m
  • LYRC036: 3m at 0.82% TREO from 30m, including 1m at 1.67% TREO (55% NdPr:TREO) from 31m
  • LYRC018: 3m at 0.57% TREO from 6m, including 1m at 1.11% TREO (51% NdPr:TREO) and 0.79% Nb2O5 from 8m
  • LYRC039: 1m at 1.01% TREO (53% NdPr: TREO) from 49m
  • LYRC025: 1m at 0.71% TREO (47% NdPr:TREO) and 1.20% Nb2O5 from 34m
• Carbonatite targets and kilometre scale potential ironstones undercover still to be drill tested
• Further assay results expected over December and January

• LYRC036: 3m at 0.82% TREO from 30m, including 1m at 1.67% TREO (55% NdPr:TREO) from 31m (Figure 2)
• LYRC018: 3m at 0.57% TREO from 6m, including 1m at 1.11% TREO (51% NdPr:TREO) and 0.79% Nb2O5 from 8m (Figure 3)
• LYRC039: 1m at 1.01% TREO (53% NdPr: TREO) from 49m (Figure 4)
• LYRC025: 1m at 0.71% TREO (47% NdPr:TREO) and 1.20% Nb2O5 from 34m

Significant intersections (Table 1) at the Lyons 27 prospect (Figure 7 and 8) include:

• LYRC047: 5m at 0.69% TREO from 20m, including 2m at 1.06% TREO (41% NdPr:TREO) from 21m (Figure 6)
• LYRC048: 2m at 0.22% TREO (43% NdPr:TREO) • LYRC045: 1m at 0.21% TREO (38% NdPr:TREO)
• Assay results are still pending for 5 of the six holes drilled at Lyons 27 (Table 2)

Potential remains for further discoveries of ironstones and carbonatites (Figures 5, 6) within the Company’s tenure where no historical REE exploration has occurred.
