17.65% Niobium & Exceptional REE Results from In-Situ Source at Wabli Creek Project

Reach Resources Limited (ASX: RR1 & RR1O) (“Reach” or “the Company”) is pleased to advise that assay results from the latest field program at Wabli Creek have identified a primary source of high grade Nb/REE mineralisation previously only found in surface eluvial samples on site (Figure 2).

HIGHLIGHTS

• In-situ or bedrock source of high-grade Niobium (Nb) and Rare Earth Elements (REE) has been discovered during the latest program of rock chip sampling at Wabli Creek, Gascoyne, W.A.
• The recently identified ovoid late-stage intrusive feature (ASX Announcement 28 May 2024) is considered the likely parental source of the Nb-Y-Ta-Ti-REE enriched pegmatites at Wabli Creek. Further, geochemistry indicates that a carbonatite association cannot be ruled out in addition to the pegmatites.
• This ovoid intrusive feature is younger than the surrounding country rock, with a diameter in excess of 3km’s and a circumference greater than 8km’s.
• Granitic pegmatite is now confirmed as a primary source of mineralisation with in-situ assay results including:
  • 17.65% Nb2O5, 0.15% Y2O3, 10.81% Ta2O5, 31.39% TiO2, 0.37% TREO (24WRCK049)
  • 13.22% Nb2O5, 0.13% Y2O3, 6.27% Ta2O5, 18.97% TiO2, 1.13% TREO (24WRCK046)
• These outstanding results have been chipped straight off bedrock (in-situ) and hold similar concentrations to the previously reported high grade weathered surface material (eluvial samples previously reported 32% Nb2O5 and 2.57% TREO -ASX Announcement 21 December 2023). Importantly, the in-situ assay results taken straight from the bedrock were taken approximately 0.5km from the historically reported 32% Nb2O5.
• The majority of the ovoid intrusive feature most prospective for Nb-Y-Ti-REE mineralisation (the margin zone), is poorly exposed and remains under-explored.
• Detailed airborne magnetic and radiometric surveys recently acquired are currently being interpreted by Southern Geoscience to identify and refine key priority targets for further exploration.
• The Company is actively progressing its heritage discussions with the Native Title custodians of the land and will return to site for additional sampling in the short term.

Most importantly, these latest high-grade assay results (17.65% Nb2O5 and 13.22% Nb2O5) confirm that the hard rock source material holds the same or similar high-grade concentrations as the weathered surface material (eluvial material), previously reported by the Company (32% Nb2O5 and 2.57% TREO - ASX Announcement 21 December 2023). Further, the in-situ samples have been chipped straight off the bedrock (in-situ) approximately 0.5km from the previously reported sample returning 32% Nb2O5.

Located in the highly prospective Gascoyne Province of Western Australia, approximately 150km north of Gascoyne Junction, the Wabli Creek project has previously reported high grade niobium and TREO eluvial results up to 32% Nb2O5 and 2.57% TREO (ASX Announcement 21 December 2023).

These latest in-situ results, in addition to the large ovoid intrusive feature (ASX Announcement 28 May 2024), provide a fundamental change in the prospectivity at Wabli Creek.

During the Company’s current program, a total of 49 rock chip samples were taken from Wabli Creek (E09/2377), during May 2024. Sampling was focused on the Priority 1 geochemical targets outlined by Sugden Geoscience (ASX Announcement 21 December 2023).
