Investor Webinar – Caesium: Mineral Resource Estimate Update

MONTREAL, July 20, 2025 /PRNewswire/ – SYDNEY, Australia – July 21, 2025 – Patriot Battery Metals (TSX: PMET, ASX: PMT, OTCQX: PMETF, FSE: R9GA) is gearing up to discuss a significant milestone with investors: the maiden Mineral Resource Estimate (MRE) for caesium at its promising Shaakichiuwaanaan Property in Quebec’s Eeyou Istchee James Bay region.

CEO Ken Brinsden will host a live investor webinar to break down the implications of this caesium discovery at the Rigel and Vega zones, both wholly owned by Patriot Battery Metals. The timing is strategic, as interest in critical minerals ramps up globally.

But the caesium news isn’t the only item on the agenda. Brinsden will also update investors on the progress of the Definitive Feasibility Study (DFS) focusing purely on lithium resources, specifically at the CV5 Shaakichiuwaanaan deposit, outlining key milestones the company expects to achieve. This dual focus underscores Patriot’s ambitions in both the lithium and caesium markets.

Shareholders and investors are invited to participate in a live Q&A session during the webinar, giving them direct access to the leadership team’s insights.

Webinar Details:

Mark your calendars: the webinar kicks off at 8:00 am Australian Western Standard Time / 10:00 am Australian Eastern Standard Time (July 22nd) / 8:00 pm Canadian Eastern Daylight Time (July 21st). Expect roughly 45 minutes of market-moving insights. Investors can register via this link:
