Ophir Metals drills 1 m of 0.92% Cs2O at Pilipas

Executive Summary

• Ophir Metals released assay results from 16 drill holes (936 m total) of its 2025 drill program at the HW3 cesium pegmatite on the Pilipas lithium property, confirming high‑grade cesium mineralization (up to 0.92 % Cs₂O over 1.0 m).
• Significant tantalum grades were also intersected, including a peak of 1,248 ppm Ta₂O₅ over 0.5 m, underscoring the multicommodity potential (cesium‑lithium‑tantalum) of the pegmatite corridor.
• The results support continuity of surface cesium mineralization into depth and highlight further exploration upside along the 4.2 km HW1–HW3 trend.

Key Details

• Drill Program Scope: 16 holes, 936 m total, completed mid‑June 2025; tight grid targeting HW3 surface expression at depth and along strike.
• Key Cesium Intercepts:
• Hole PLP25‑027 – 2.5 m @ 0.41 % Cs₂O (including 1.0 m @ 0.92 % Cs₂O).
• Hole PLP25‑028 – 0.5 m @ 0.26 % Cs₂O within pegmatite.
• Holes PLP25‑025 & PLP25‑037 – basalt margins returned 1.5 m @ 0.46 % Cs₂O and 1.4 m @ 0.21 % Cs₂O respectively.
• Tantalum Highlights:
• Hole PLP25‑032 – peak 1,248 ppm Ta₂O₅ over 0.5 m (within a larger 375 ppm Ta₂O₅ over 3.8 m interval).
• Additional high‑grade intervals: 328 ppm Ta₂O₅ over 4.0 m (PLP25‑037) and 375 ppm Ta₂O₅ over 3.8 m (PLP25‑032).
• Overall Cesium Frequency: 16 separate samples > 0.06 % Cs₂O; multiple intervals > 0.20 % Cs₂O across the pegmatite system.
• Lithium Context: Prior 2024 drilling at HW1 returned 53.2 m @ 1.22 % Li₂O, reinforcing multicommodity potential.
• Pollucite Observation: Visual logging noted mineralization consistent with pollucite in PLP25‑027 coincident with elevated Cs grades; XRD confirmation pending.
• Geochemical Prospectivity: Favorable K/Rb, Nb/Ta, Zr/Hf and Mg/Li ratios from 2024 grab samples indicate additional LCT (lithium‑cesium‑tantalum) potential along the corridor.
• QA/QC Protocol: Half‑core sent for analysis; SGS Canada performed sodium peroxide fusion ICP‑AES/MS for multielements and fire assay for Au; certified reference materials, blanks, and duplicates inserted at ~5 % each. No significant QA/QC issues identified.
• Qualified Person: Kaylyn Niemetz, P.Geo., Dahrouge Geological Consulting Ltd., NI 43‑101 qualified person, reviewed and approved all technical content.
