EXPLORATION TARGET FOR THE SHAAKICHIUWAANAAN LITHIUM PROJECT OUTLINES DISTRICT SCALE OPPORTUNITY, QUEBEC, CANADA

Patriot Battery Metals Inc. has outlined a maiden exploration target for its 100-per-cent-owned Shaakichiuwaanaan property -- formerly known as Corvette -- located in the Eeyou Istchee James Bay region of Quebec, which is accessible year-round by all-season road and is proximal to major regional power line infrastructure.

Highlights:

• Significant exploration target outlines the potential for additional tonnage at the Shaakichiuwaanaan property (formerly known as Corvette);
• Approximately 146 million tonnes to 231 million tonnes at 1.0 per cent to 1.5 per cent Li2O (lithium oxide);
• The potential quantity and grade of the exploration target are conceptual in nature; there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the exploration target being delineated as a mineral resource; the exploration target has been determined based on the interpretation of a consolidated data set of surface rock sample descriptions and assays, outcrop mapping and descriptions, drill hole logs and core sample assays, geophysical surveys, and remote sensing data;
• Exploration target is in addition to (does not include) the Shaakichiuwaanaan mineral resource estimate announced concurrently;
• Exploration target only considers the CV lithium trend and immediately proximal areas;
• Completed by BBA Engineering Ltd., a consultant independent of the company.

Darren L. Smith, vice-president of exploration, commented: "This exploration target highlights the scale of potential remaining to be assessed by the drill bit at the Shaakichiuwaanaan project. The project hosts eight distinct lithium pegmatite clusters along the CV lithium trend, of which only three have had meaningful drill testing (CV5, CV13 and CV9), with each remaining open at depth and along strike. The potential for additional lithium pegmatite mineral resource the project continues to hold, as captured by the exploration target, is truly remarkable on the global stage."

Ken Brinsden, president, chief executive officer and managing director, commented: "As expected, this exploration target gives clear guidance to the market with respect to the untested potential present at the Shaakichiuwaanaan project. A significant amount of drilling will be required in order to confirm the presence of mineralized pegmatite and further advance the level of confidence towards a mineral resource estimate. However, the potential for further discovery of significance is clear and present."

The exploration target (also known as a target for further exploration) for the Shaakichiuwaanaan project is approximately 146 million tonnes to 231 million tonnes at 1.0 per cent to 1.5 per cent Li2O.

The potential quantity and grade of the exploration target are conceptual in nature. There has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource. The exploration target has been determined based on the interpretation of a consolidated data set of surface rock sample descriptions and assays, outcrop mapping and descriptions, drill hole logs and core sample assays, geophysical surveys, and remote sensing data (refer to methodology of determination for the exploration target for more information about the base on which the disclosed potential quantity and grade have been determined).

The exploration target has been completed in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, and the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves, 2012 edition (JORC). BBA Engineering Ltd., a consultant who is independent of the company, completed the exploration target.

The exploration target for the project is exclusive of (does not include) the Shaakichiuwaanaan mineral resource estimate, announced concurrently by the company (see news release dated Aug. 5, 2024) and only considers the CV lithium trend and immediately proximal areas. The exploration target has been presented as an approach to assess the potential endowment of the project or the potential to host additional mineral resources of lithium pegmatite, subject to the success of future mineral exploration at the property and outside of that already defined.

In its second MRE (80.1 million tonnes at 1.44 per cent Li2O indicated and 62.5 million tonnes at 1.31 per cent Li2O inferred; see news release dated Aug. 5, 2024), the Shaakichiuwaanaan project is already firmly established -- by a wide margin -- as the largest lithium pegmatite MRE in the Americas and eighth largest globally. With the determination of this accompanying exploration target, which is exclusive of (does not include) the MRE, the project has been further distinguished on the global stage with respect to its district-scale lithium pegmatite potential to drive exploration in future years.

The company intends to test the validity of the exploration target in future exploration programs at the project, beginning in 2025 and extending over a several-year period. Systematic diamond drilling (NQ core size) of the known spodumene pegmatite clusters and corridors between and proximal, which collectively form the basis of the exploration target, will be the primary method of exploration.

Methodology of determination for the exploration target

The exploration target has been completed by BBA Engineering Ltd., a consultant independent of the company. The basis on which the quantity and grade of the exploration target has been determined includes a review and interpretation of an extensive property-scale data set of surface rock sample descriptions and assays (greater than 1,500 grab, chip and channel samples), pegmatite outcrop mapping and descriptions (greater than 1,000 outcrops/observations), drill hole logs and core sample assays, geophysical surveys (magnetics, induced polarization/resistivity), and remote sensing data (lidar and orthophoto).

BBA's method of determination included a detailed review of the consolidated data set followed by 3-D modelling to create a conceptual volume for all implied LCT (lithium/cesium/tantalum) pegmatite bodies within and proximal to the CV lithium trend. To estimate a tonnage the pegmatite, specific gravity (SG) used was approximately 2.626 based on the same linear regression formula as the latest MRE (SG equals 0.0688 times Li2O per cent plus 2.625). An associated grade was then applied. The implied tonnage of each volume was then reduced by a factor to account for the likelihood of being mineralized at a reasonable grade, which was then further discounted to arrive at a final range of tonnage and lithium grade. The estimated tonnage was then rounded to the nearest million tonnes and the grade rounded to the nearest 0.1 per cent Li2O.

The 3-D modelling of the implied pegmatite volumes was also constrained by the known spodumene pegmatite clusters at the property, including their interpreted corridors of potential along strike. The volumes were further capped at a vertical depth from surface of 200 metres. The areas of the CV lithium trend with defined mineral resources (the CV5 and CV13 pegmatites, a collective 6.9 kilometres of trend) were not included in the determination of the exploration target. Therefore, the exploration target for the Shaakichiuwaanaan project is exclusive of (does not include) the mineral resources presently defined at the project.
