Ophir Metals Corp. (TSX-V: OPHR) (OTCQB: OPHRF) (FSE: 80M) is pleased to announce assay results for 16 drillholes from the 2025 drill program on the Pilipas Lithium Property, located in the Eeyou Istchee James Bay region, Quebec. The Project is located proximal to existing hydroelectric power that flanks the Property to the east, and an all-season road that crosses the western side of the Property.
“Drilling at HW3 has confirmed cesium mineralization grading nearly 1% over one meter in the subsurface. Combined with the ~11 m by 4 m zone of elevated cesium values returned from surficial channel sampling at HW3 (See news release dated February 3, 2025), and the lithium-bearing pegmatite identified at HW1 that returned 53.2 m at 1.22% Li2O from drilling in 2024 (See news release dated December 11, 2024), these results highlight the strong multi-commodity potential at Pilipas. Few pegmatite fields worldwide demonstrate both cesium and lithium mineralization, and we believe this provides a strong foundation for follow-up exploration,” comments Shawn Westcott, CEO of Ophir.
Highlights:
The 2025 drill program concluded in mid-June with the completion of 16 drill holes totaling 936 m at the HW3 Cesium Pegmatite (Table 2). The analytical results reported herein represent all drill holes completed as part of the exploration program. Drillholes were planned on a tight grid spacing targeting the surface expression at depth and along strike.
Drilling in 2025 confirmed that the HW3 Pegmatites are present to moderate depth and capable of hosting strong cesium mineralization, as demonstrated by the intercept of 0.92% Cs₂O over 1.0 m (Figure 1). The cesium enrichment is not limited to a single intercept, with sixteen separate samples from 2025 drillholes returning values >0.06% Cs₂O. Intervals such as 0.26% Cs₂O over 0.5 m and 0.21% Cs₂O over 1.42 m demonstrate that the system is highly anomalous in cesium mineralization across multiple horizons.
Strongly anomalous to high-grade tantalum results were also returned from the pegmatites at HW3, with thirty-one (31) samples returning >50 ppm Ta2O5, the highest of which returned 1,248 ppm Ta₂O₅ over 0.5 m (Table 1). Additional intervals of 328 ppm Ta2O5 over 4.0 m and 375 ppm Ta2O5 over 3.8 m were returned from drillholes PLP25-037 and PLP25-032, respectively. These results highlight the multi-commodity potential of the system, extending beyond cesium and lithium.
Although pollucite in drill core has yet to be confirmed by X-ray diffraction (XRD), visual logging noted minerals consistent with pollucite in one interval of PLP25-027 (Figure 1), coincident with elevated cesium grades. This zone is consistent with the pollucite-bearing material confirmed by XRD in 2024 surface channel samples from the same outcrop area, supporting continuity of cesium mineralization from surface into the subsurface. Pollucite, the principal mineralized material cesium, is globally rare, and its occurrence at HW3 is significant. The 2025 drill program results demonstrate that the pegmatites at Pilipas are highly fractionated, consistent with the processes that concentrate cesium, lithium, and tantalum. Much of the 4.2 km corridor between HW1 and HW3 showings has limited outcrop exposure, providing scope for additional discoveries along the pegmatite trend.
Additionally, other areas of the Pilipas Property remain highly prospective for hosting Lithium-Cesium-Tantalum (“LCT”) mineralization for follow-up work, as indicated by strong geochemical fertility ratios obtained in pegmatite grab samples collected in 2024 (See news release dated May 21, 2025). The geochemical ratios of K/Rb, Nb/Ta, Zr/Hf, and Mg/Li are commonly used to assess the potential for pegmatites to host LCT mineralization. Fertile pegmatites (and their source melts) typically have ratios of K/Rb < 150, Nb/Ta < 5, Zr/Hf < 18, and Mg/Li < 10. The more of these indices that are met, the higher the likelihood that a given pegmatite could host LCT mineralization (See Figure 2).

Quality Assurance / Quality Control
Drill core was saw-cut with half-core sent for geochemical analysis and half-core remaining in the box onsite. All core samples were securely transported by field staff to SGS Canada’s laboratory in Radisson, QC for standard sample preparation (code PRP90) which includes drying at 105°C, crush to 90% passing 2 mm, riffle split 250 g and pulverize 85% passing 75 microns. The pulps were then shipped to SGS Canada’s laboratory in Burnaby, BC where they were subsequently analyzed for multi-element (including Li, Cs and Ta) using sodium peroxide fusion with ICP-AES/MS finish (code GE_ICM91A50). Gold analysis was performed using Au by fire assay (Code GE_FAA30V5). A Quality Assurance/Quality Control protocol was incorporated into the program and included the insertion of certified reference materials and silica blanks at a rate of approximately 5% and 5%, respectively. Additional analysis of pulp-split and reject-split sample duplicates was also completed at a rate of approximately 5% to assess analytical precision at different stages. SGS Canada is independent of the Company.
