Capacitor Metals Corp. Announces Initiation of Metallurgical Test Program

(via TheNewswire)

July 2, 2026 – TheNewswire - Capacitor Metals Corp. (the “Company” or “Capacitor”) is pleased to announce the initiation of the metallurgical program on material from the Upper Fir Tantalum & Niobium Deposit in British Columbia at SGS Burnaby under the direction of Michel Robert (M.Sc.). The goal of the program is to process raw material from the Upper Fir Deposit through to the production of a tantalum-niobium (Ta-Nb) flotation concentrate. Historic recovery rates for the flotation concentrate are +75%. It is intended that this concentrate will then be used to test the extraction and production of separated final tantalum and niobium oxides for delivery to industry.

The Company intends to transport 2 tonnes of crushed rock from the 2,000-tonne Upper Fir Deposit bulk sample to SGS Canada Burnaby, from the ~120 tonnes in storage in Richmond. It is expected that the pilot plant program will run until fall 2026.

The historic Preliminary Economic Assessment (PEA) completed by AMEC in 2011 for the Upper Fir Tantalum & Niobium Deposit was based upon the process design flow sheet producing a commercially marketable tantalum/ niobium concentrate. In subsequent work, estimated overall recovery rates increased to 77.2% for tantalum and 75.1% for niobium, over the base case of 65-70% in the PEA. Within the rougher and cleaner flotation circuit the recoveries achieved in open circuit exceeded 96% for tantalum and 92% for niobium.

The Upper Fir Tantalum & Niobium Deposit is one of the world’s largest defined resources of tantalum, with a current indicated resource of 48.4 M tonnes at 197 ppm tantalum and 1,610 ppm niobium, and an inferred resource of 5.4 M tonnes at 191 ppm tantalum and 1,760 niobium. The indicated resource amounts to 21M pounds of tantalum and 171M pounds of niobium. The inferred resource amounts to 2.2M pounds of tantalum and 21M pounds of niobium.

About Capacitor Metals Corp.

Capacitor Metals Corp. is a British Columbia Incorporated Company focused on the development of the Blue River Tantalum-Niobium Property located in British Columbia, Canada. The Company is positioned to be one of the lowest cost tantalum-niobium producers globally, with a specific focus on being a long-term supplier of tantalum and niobium to the global market.

The Blue River Property is a fully serviced site in mining-friendly British Columbia, Canada with excellent infrastructure close at hand, including rail, paved road, water, and power adjacent to project site.

The Property contains three defined deposits of tantalum and niobium, the Verity, the Fir and the Upper Fir, and an additional 20+ mineralized known exploration targets.

The Upper Fir Tantalum & Niobium Deposit is advanced with significant work already completed. CAD$34M+ has been spent to date, including +59,000 meters drilled in 271 drill holes, an historical Preliminary Economic Assessment (“PEA”), community consultations, and preliminary metallurgical and environmental work.

Within the Blue River Property, the Upper Fir deposit has a significant historical indicated resource of 9.6M kg contained tantalum and 77.8M kg contained niobium plus an historical inferred resource of 1.0M kg contained tantalum and 9.6M kg contained niobium.
