(TSX-V:EVNI) (\"EVNi\" or the \"Company\") is pleased to announce positive results from a continuous pilot-scale bioleaching and downstream metals recovery test program conducted on flotation concentrates from its W4 Nickel Project near Timmins, Ontario (see press releases dated May 2, 2023 and September 26, 2023).Bioleaching is a processing technology that eliminates the need for expensive smelters, roasters, autoclaves, and acid plants required for other processing operations. This significantly reduces upfront capital costs and lowers operating expenses by avoiding high energy consumption, maintenance, and complex materials handling. Traditional processing requires shipping concentrate long distances to third-party facilities whereas, bioleaching can be performed on site, reducing transportation costs and allows producers to retain the smelting margin rather than paying treatment and refining charges.Bioleaching uses naturally occurring bacteria to extract nickel at ambient temperatures and pressures, producing substantially lower greenhouse gas emissions than the current energy-intensive alternatives avoiding sulfur dioxide emissions, slag generation, and the high acid consumption.Bioleaching produces intermediate products such as nickel sulphate and nickel MHP suitable for conversion into battery-grade materials and creates a more direct and transparent pathway to electric vehicle battery manufacturers. EVNi's advances in nickel bioleaching are now demonstrating scalability and reliability, positioning it as a compelling alternative for future nickel projects.\"After more than four years of development and testing, the results being reported today demonstrate that EV Nickel is ready to adv...
