Preliminary Mineralogy Confirms Spodumene as the Dominant Li-

bearing Mineral at the CV5 Pegmatite, Preliminary Metallurgical

Program Initiated, Corvette Property, Quebec

Vancouver, BC, Canada

Highlights

• Initial mineralogy completed on select samples from drill holes CF21 -001 and 002 (CV5

Pegmatite), 004 (CV6 Pegmatite), and 014 (CV12 Pegmatite), indicate:

o Spodumene is the dominant lithium-bearing mineral present – of the samples probed

grading >0.4% Li2O, spodumene accounts for 86-99% of the lithium deportment

o No significant petalite, lithium-phosphate minerals, or apatite present

o Columbite/tantalite are the dominant tantalum-bearing minerals present

• Preliminary Metallurgical program initiated at SGS Canada (Lakefield) supported by 225 kg

of sample drill core from holes CF21-001 and 002 at the CV5 Pegmatite

o Primary objective is to develop preliminary f lowsheet to produce spodumene

concentrate – grading >6% Li2O – at high recovery

o Focused on head sample characterization and mineralogy, grindability, heavy liquid

separation (HLS), dense media separation (DMS), magnetic separation, and flotation

June 7, 2022 – Patriot Battery Metals Inc. (the “Company” or “Patriot”) (CSE: PMET) (OTCQB:

PMETF) (FSE: R9GA) is pleased to announce the results of initial mineralogical characterization of drill

core samples from the Company’s wholly owned Corvette Property (the “Pro perty”), as well as the

commencement of a preliminary metallurgical test program. The Property is located proximal to the

regional and all-weather Trans-Taiga Road and powerline infrastructure, within the James Bay Region of

Quebec.

Initial mineralogical work was completed by SGS Canada on twenty -two (22) drill core analytical reject

samples collected across four (4) of the first five (5) drill holes to target lithium pegmatite in 2021 –

CF21-001 and 002 (CV5 Pegmatite), CF21- 004 (CV6 Pegmatite), and CF21- 014 (CV12 Pegmatite). All

samples were analyzed by XRD ( X-ray diffraction) for modal mineralogy, four (4) samples by TIMA-X

(Quantitative Evaluation of Materials by Scanning Electron Microscopy) for mineral associations and

elemental deportment, and four (4) samples by Electron Probe Micro-Analysis (EPMA) and Laser Ablation

by Inductively Coupled Plasma Mass Spectrometry (LA by ICP-MS) for mineral chemistry. The purpose

of the mineralogy work is to provide a preliminary characterization of the lithium pegmatite at Corvette,

and to orient ahead of preliminary metallurgical (mineral processing) test work.

The modal mineralogies for the pegmatites, as determined by XRD, support geological core logging. The

major minerals include quartz, feldspar (albite, microcline) , and spodumene, with minor to accessory

muscovite and tourmaline. Uncommon accessory minerals (typically <3% if present) include lepidolite,

chlorite, biotite, and beryl.

The combined results of the mineralogy and mineral chemistry indicate that spodumene is the domina nt

lithium-bearing mineral at Corvette. No petalite or lithium phosphate minerals were observed from XRD;

although, trace to minor lepidolite (Li mica) and lithium bearing muscovite and tourmaline are present in

some samples. However, where spodumene is present, it is the dominant lithium -bearing mineral .

Moreover, of the samples probed grading >0.4% Li2O, spodumene accounts for 86-99% of the lithium

deportment, further supporting that lithium grade is carried by spodumene. Collectively, these preliminary

results indicate that the mineral spodumene carries the vast majority of the lithium at Corvette and supports

the visual observations by the field geologists.

An additional suite of core billets and analytical rejects are being compiled for follow -up mineralogical

analysis that will include XRD, TIMA-X, EPMA, LA by ICP-MS, as well as thin section analysis. The

work will improve the understanding of the pegmatites at Corvette and guide metallurgical test programs.

In addition to the initial mineralogical work, a preliminary metallurgical test program is now underway at

SGS Canada’s Lakefield, ON, facilit y. Approximately 225kg of quarter -core NQ samples, comprising

mineralized intervals from drill holes CF21 -001 and 002, have been received by the lab for the initial

testwork. Material preparation has recently been completed and test work begun.

The testing is anticipated to include head sample characterization and mineralogy, grindability, heavy liquid

separation (HLS), dense media separation (DMS), magnetic separation, and flotation. The primary

objective of the preliminary metallurgical program is to evaluate the beneficiation performance of the

Corvette material using a conventional lithium pegmatite flowsheet, and to produce a spodumene

concentrate of >6% Li2O and <1% Fe2O3, while maximizing lithium recovery.

About the CV Lithium Trend

The CV Lithium Trend is an emerging spodumene pegmatite district discovered by the Company in 2017

and spans the FCI West, FCI East, and Corvette claim blocks. The core area includes an approximate 2 km

long corridor (the CV5-1 Corridor), which is part of the more than 25-km long CV Lithium Trend extending

across the Property. It consists of numerous spodumene pegmatite occurrences, which include the CV1,

CV2, CV3, CV5, CV6, CV7, and CV11 pegmatites and has returned drill intercepts of 0.94% Li2O and 117

ppm Ta2O5 over 155.1 m (CF21- 002), and 2.22% Li 2O over 70.1 m, including 3.01% Li2O over 40.7 m

(CV22-017). Drilling to date indicates a principal pegmatite body of significant size and has been traced by

drilling over a distance of at least 1.4 km, and therefore, is considerably larger than that observed in outcrop.

The high number of well -mineralized pegmatites in this core area of the trend indicate a strong potential

for a series of relati vely closely spaced/stacked, sub -parallel, and sizable spodumene -bearing pegmatite

bodies, with significant lateral and depth extent, to be present.
