Ophir to Drill High-Grade Cesium Discovery at the Pilipas Property, James Bay, Quebec
Vancouver, May 21, 2025 - Ophir Metals Corp. (TSXV: OPHR) (OTCQB: OPHRF) (FSE: W0J) ("Ophir" or the "Company") is pleased to announce that planning is underway for a drill program targeting the high-grade cesium discovery at the HW3 Pegmatite on the Pilipas Lithium Property (the "Property" or "Project"). Pilipas is located in Eeyou Istchee region of James Bay, Quebec, proximal to existing hydroelectric power that flanks the Property to the east, and an all-season highway that bisects the western side of the Property.
"Our high-grade cesium discovery at HW3 has the unique potential to meet part of the reported worldwide shortage in cesium supply, which is just 50 m from the main transport highway through the region. HW3 is one of only a select few pegmatites in the James Bay region to host high-grade cesium, which makes HW3 both very rare and an incredibly attractive drill target," comments Shawn Westcott, CEO of Ophir Metals.
The drill program is currently planned to commence during the first week of June. The program will be approximately 1,000 m and will be focused on testing the known cesium zone at depth and to the south, where the pegmatite remains open. The surface area of the cesium enrichment within the HW3 outcrop is at least approximately 11 x 4 m (Figure 1) as identified from the recently completed channel sampling program.
HW3 Cesium Pegmatite Highlights (See news release dated February 3rd, 2025)
- Well-mineralized channel intervals at the HW3 Pegmatite
- 1.4 m at 6.00% Cs2O including 0.5 m at 12.40% Cs2O - PCH24-001 (Figure 2)
- 5.0 m at 1.46% Cs2O, including 1.0 m at 5.30% Cs2O PCH24-002
- 4.0 m at 1.81% Cs2O, including 2.0 m at 2.30% Cs2O - PCH24-003 (Figure 2)
- 14.2% Cs2O and 4.24% Cs2O from outcrop grab samples
- HW3 Pegmatite remains open in multiple directions
- Pollucite mineralization confirmed by Quantitative XRD analysis
The HW3 Pegmatite is approximately 15 m by 23 m in size with the southern extent plunging under cover of swamp with no defined contact observed, therefore remaining open in several directions.

Cesium is listed as a "Critical Mineral" in Canada and other jurisdictions around the world (Canada's Critical Minerals). To qualify as a "critical mineral", the commodity must have a supply chain that is threatened and a reasonable chance of being produced in Canada. It must also meet one of the following criteria: be essential to Canada's economic or national security, be required for the transition to sustainable low carbon and digital economy and/or position Canada as a sustainable or strategic partner within global supply chains.
Cesium has multiple commercial applications from environmentally friendly drilling fluids to a variety of chemical and electrical applications. Cesium isotopes are used as an atomic frequency standard within atomic clocks, and plays a vital role in global positioning systems (GPS), aircraft guidance systems and the implementation of 5G internet and cellular telephone transmissions (USGS - Mineral Commodity Summary).
Due to the lack of global supply, the only primary cesium mine in operation, the Tanco mine in Manitoba (owned by Tantalum Mining Corporation of Canada), has faced international competition for the supply of the mine's cesium. The Tanco mine is also evaluating options for long-term redevelopment in order to extract the remaining cesium that is contained within the mine. (CBC Reporting on the Tanco Mine in Manitoba).

Other areas of the Pilipas Property also remain highly prospective for hosting pollucite mineralization, as indicated by strong geochemical fertility ratios obtained in pegmatite grab samples. 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 Lithium-Cesium-Tantalum ("LCT") mineralization.
Eighty-one (81) surface samples collected during the 2024 work programs met all four of these fertility criteria, while an additional one hundred and seventy-two (172) samples met three out of the four criteria (Figure 3). All of the surface and channel samples containing visible Cs and/or Li mineralization meet all four of the criteria, along with numerous other samples from outcrops lacking visible mineralization. This indicates a highly fractionated parental magma with strong potential for additional pegmatite outcrops to host Cs-Li mineralization, particularly those surrounding the HW2 and HW3 areas.

Ophir also announces that, pursuant to its stock option plan, it has granted an aggregate of 200,000 options to purchase common shares in the capital of the Company to certain consultants of the Company, exercisable at a price of $0.10 per share for a period of 5 years from the date of grant.
Quality Assurance / Quality Control
All channel samples were collected in the field using a hammer and chisel after using a gas-powered diamond saw to cut 3-4" deep channels. Channel locations were obtained using a handheld GPS with samples placed in pre-labelled sample bags. Metal tags with the sample numbers were left within the sample meter cuts. Samples were securely transported by field staff to SGS Canada's laboratory in Val d'Or, 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 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) and cesium overlimit analysis completed by acid digest for alkaline elements (code GC_AAS49C). A Quality Assurance/Quality Control protocol was incorporated into the program and included the insertion of certified reference material at and blanks at a rate of approximately 5% and 5%, respectively. SGS Canada is independent of the Company.
Management cautions that prospecting surface rock samples and associated assays, as discussed herein, are selective by nature and represent a point location, and therefore may not necessarily be fully representative of the mineralized horizon sampled.
