Patriot Files NI 43-101 Technical Report on the
Shaakichiuwaanaan Mineral Resource Estimate, Quebec,
Canada
August 29, 2025 – Montréal, QC, Canada August 30, 2025 – Sydney, Australia
Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX: PMET) (ASX: PMT)
(OTCQX: PMETF) (FSE: R9GA) is pleased to announce it has filed on SEDAR+ a technical
report (the “Technical Report”), prepared in accordance with National Instrument 43-101 –
Standards of Disclosure for Mineral Projects (“NI 43-101”), titled “ Mineral Resource Estimate for
the Shaakichiuwaanaan Project, James Bay Region, Québec, Canada”, with an Issue Date of August 28,
2025, and Effective Date of June 20, 2025. The filing follows the July 20, 2025, news release of a
updated Mineral Resource Estimate for the Shaakichiuwaanaan Project’s CV5 and CV13 LCT
Pegmatites, including the Rigel and Vega caesium zones.
The Technical Report has been prepared by BBA Inc., with contributions from Primero Group
Americas Inc., both consulting groups independent of the Company, in accordance with NI 43-101.
The report is available on SEDAR+ and will shortly be available on the Company’s website.
Clarification Regarding the Mineral Resource Estimate Updates in 2025
Since the beginning of the 2025, the Company has disclosed two updates of the Mineral Resource
Estimate (“MRE”) at the Property, the results of which are included in the Technical Report. The
Company would like to provide the following clarifications regarding these updates.
The first update, announced on May 12, 2025, in the press release titled “Significant Mineral Resource
Upgrade at Shaakichiuwaanaan Lithium Project to Underpin Impending Feasibility Study ” (the “May 12
PR”), disclosed an updated Consolidated MRE at the Property focused on the CV5 and CV13
spodumene pegmatites. While the May 12 PR constituted material information warranting timely
disclosure, a careful assessment by the Company of its impact on operational planning, economic
outlook, and strategic direction led management to conclude that it did not constitute a “material
change” in respect of the Company for Canadian securities law purposes. While the resource
category tonnes upgrade from inferred to the indicated category were important, they did not
alter the Project’s execution timeline, capital allocation priorities, or underlying technical
assumptions to that already described in the public domain. As a result, the Company determined
that it was not required to file an updated technical report under NI 43-101 in connection with
the May 12 PR.
Conversely, the Company considers the updates contained in its press release dated July 20, 2025,
titled “ World’s Largest Pollucite-Hosted Caesium Pegmatite Mineral Resource Defined at
Shaakichiuwaanaan” (the “ July 20 PR ”), to be material given that the Company disclosed for the
first time a maiden caesium resource at the Rigel and Vega zones which was concluded to be the
world’s largest known pollucite-hosted caesium pegmatite Mineral Resource. The July 20 PR
therefore triggered the obligation under NI 43-101 to file this Technical Report within 45 days of
its release.

2 The Consolidated MRE cut-off grade is variable depending on the mining method and pegmatite (0.40% Li 2O
open-pit, 0.60% Li2O underground CV5, and 0.70% Li2O underground CV13). A grade constraint of 0.50% Cs 2O
was used to model the Rigel and Vega caesium zones, which are entirely within the CV13 Pegmatite’s open-pit
mining shape. The Effective Date of the MREs is June 20, 2025 (through drill hole CV24-787). Mineral Resources
are not Mineral or Ore Reserves as they do not have demonstrated economic viability.
