Drill Program Update:
Drill holes CV22-063 and 066, with 39.9 m and 113.4 m core length intercepts of spodumene-bearing pegmatite, respectively, have extended the strike length of the principal lithium pegmatite to at least 2,000 m, as tested by drilling, spanning laterally from drill hole CF21-004 through CV22-063/066
As of August 24th, 2022, a total of 15,497 m over fifty-three (53) holes have now been completed over the 2022 drill campaign – 4,345 m over 20 holes in the winter program, and 11,152 m over thirty-three (33) holes in the summer program.
Nineteen (19) drill holes currently en route to or in process at the analytical lab
Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX-V: PMET) (OTCQB: PMETF) (FSE: R9GA) is pleased to announce core assay results for an additional six (6) drill holes (CV22-037, 038, 039, 042, 043, and 044) completed as part of the summer phase of the 2022 drill campaign at its wholly owned Corvette Property (the “Property”), located in the James Bay Region of Quebec. The target drill area – at the CV Lithium Trend – is located approximately 13.5 km south of the regional and all-weather Trans-Taiga Road and powerline infrastructure.
The Company is pleased to announce some of the strongest lithium mineralized intervals of the drill campaign to date at Corvette, including the strongest based on a lithium grade-times-width metric – CV22-042. This drill hole returned a continuous pegmatite interval (core length) of 159.7 m grading 1.65% Li2O, including 9.0 m of 4.12% Li2O, and was completed as follow-up along strike eastwardly of the 2.22% Li2O over 70.1 m intercept in drill hole CV22-017 (see news release dated May 24, 2022) (Figures 1 and 2). Additionally, drill hole CV22-044 was completed as a step-back to CV22-017 to test the high-grade zone at depth and returned 86.2 m grading 2.13% Li2O, including 18.0 m of 3.07% Li2O (Figure 3). Collectively, both drill holes (CV22-042 and 044) have extended the high-grade lithium zone – first intersected in CV22-017 – along strike and to depth, respectively.
Ken Brinsden, Non-Executive Chairman and Director, comments: “The scope of lithium mineralization at Corvette is incredible, with further strong intercepts from the summer program continuing to demonstrate the scale and grade of the mineralized envelope. Remaining open to the east, west, and to depth, in addition to the numerous other lithium pegmatite targets on the Property, the Corvette Project remains highly prospective beyond what we have found to date. Corvette is one of the world’s great lithium raw materials discoveries with full credit to the team as we continue to realize its potential.”
Drill holes CV22-042 and 044 highlight the high-grade nature of the lithium pegmatite located at the eastern end of the drill area, proximal to the CV1 Pegmatite outcrop. Over the 159.7 m (1.65% Li2O) pegmatite intercept in drill hole CV22-042, a total of twenty-eight (28) samples, with intervals ranging from 1.0 m to 1.15 m, assayed greater than 3.0% Li2O, seven (7) over 4.0% Li2O, and four (4) over 5.0% Li2O, to a peak of 6.74% Li2O over 1.15 m. With respect to drill hole CV22-044, over its 86.2 m (2.13% Li2O) pegmatite intercept, a total of twenty-seven (27) samples assayed greater than 3.0% Li2O, eight (8) over 4.0% Li2O, to a peak of 5.83% Li2O, over individual sample intervals of 0.9 m to 1.23 m.
Additionally, drill holes CV22-063 and 066, targeting the principal pegmatite approximately 100 m along strike of the high-grade intersection in CV22-042, have returned spodumene-bearing pegmatite intercepts (core length) of 39.9 m and 113.4 m, respectively, and are currently being processed at site. These drill holes (CV22-063 and 066) have extended the strike length of the principal spodumene-bearing pegmatite body to at least 2,000 m, as tested by drilling, spanning laterally from drill hole CF21-004 through CV22-063/066 (Figure 1). The principal spodumene-bearing pegmatite body remains open at both ends along strike, and at depth.
Drill holes CV22-038 and 043 were completed as step-outs westwardly from the CV5 Pegmatite outcrop towards the CV6 Pegmatite outcrop (Figure 1). Both drill holes returned strong lithium mineralization over a wide and continuous pegmatite interval, assaying 1.42% Li2O over 59.3 m, including 2.06% Li2O over 7.2 m (CV22-038), and 1.68% Li2O over 22.7 m, including 3.13% Li2O over 7.0 m (CV22-043). A total of four (4) samples assayed greater than 4% Li2O in drill hole CV22-043, to a peak of 5.49% Li2O over 1.0 m. Lithium mineralization is characterized by large spodumene crystals hosted within a typical quartz-feldspar pegmatite with accessory muscovite and is typical of the primary mineralization style observed in drill core from the central and eastern portions of the overall pegmatite body(s) (Figures 4 and 5).
Drill holes CV22-038 and 043 are the westernmost drill holes completed to date from 2022 in which core assays have been received and are situated approximately 1.7 km along strike of the eastern most drill holes with assays received to date, highlighted by CV22-042 (1.65% Li2O over 159.7 m). The strong lithium grades encountered in CV22-038 (1.42% Li2O over 59.3 m) and 043 (1.68% Li2O over 22.7 m), coupled with similar mineralogy and textures in distal drill holes located along strike (e.g., CV22-017, 028, 030, 042, and 043), confirm that the high-grade nature of the lithium mineralization is present at significant lateral distance along the principal pegmatite body and collectively emphasize the considerable size of the system.
As of August 24th, 2022, a total of 15,497 m (53 holes) have been completed over the 2022 drill campaign, including 11,152 m (33 holes) as part of the summer program – drill holes CV22-035 through 067. Core assay results are announced herein for drill holes CV22-037, 038, 039, 042, 043, and 044. A summary of the summer program’s lithium (and tantalum) intercepts for which core analysis has been reported, including the six (6) drill holes reported herein, is presented in Table 1 and drill hole locations in Figure 1. Select core photos are presented in Figures 2, 3, 4, and 5. A summary of the 2021 and 2022 winter drill results may be found on the Company’s website.

Drill holes CV22-037 and 039 were completed at a tighter spacing – 50 m compared to the typical 100 m – at the eastern portion of the current drill area, targeting pegmatite at shallow depths. The objectives of these two (2) drill holes were to further the understanding of the CV1 Pegmatite outcrop and local geology near-surface at this location and to ascertain its relationship with the principal pegmatite body at depth. The drill holes returned relatively wide pegmatite intercepts with variable levels of mineralization; 0.41% Li2O and 129 ppm Ta2O5 over 52.0 m, including 1.49% Li2O and 169 ppm Ta2O5 over 5.2 m (CV22-037), and 0.56% Li2O and 158 ppm Ta2O5 over 40.5 m, including 1.55% Li2O and 179 ppm Ta2O5 over 10.8 m (CV22-039). Lithium pegmatites are commonly zoned, and although less mineralized than adjacent holes where assays have been received, both drill holes demonstrate high-grade potential with 3.95% Li2O over 0.5 m (CV22-037) and 3.34% Li2O over 1 m (CV22-039). Both CV22-037 and 039 overlie the high-grade lithium zone intersected in drill holes CV22-017 and 044, which is interpreted to extend east-west and begin at moderate depth (~100 m vertical depth).
Additionally, the drill data received from CV22-037 and 039 provide a strong indication that the CV1 Pegmatite outcrop represents the surface expression of separate pegmatite body trending sub-parallel and in close proximity to the principal pegmatite body (Figure 1).
Strong grades of tantalum continue to be present in the drilled pegmatite at Corvette, and also continue to be more prevalent over the eastern areas. In addition to the high-grade lithium in drill holes CV22-042 and 044, grades of tantalum include 193 ppm Ta2O5 (1.65% Li2O) over 159.7 m (CV22-042), and 163 ppm Ta2O5 (2.13% Li2O) over 86.2 m (CV22-044). Additionally, the grades of tantalum appear to increase along with the grades of lithium in these two drill holes – 209 ppm Ta2O5 (3.04% Li2O) over 37.0 m (CV22-042), and 265 ppm Ta2O5 (3.07% Li2O) over 18.0 m (CV22-044). Additionally, drill hole CV22-042 returned 2,570 Ta2O5 (1.29% Li2O) over 1 m, which is the highest grade of tantalum returned to date at the CV5-1 pegmatite corridor. Tantalum continues to be a secondary commodity of strong interest at Corvette and recovery into a marketable concentrate will continue to be explored as flowsheet development advances.
The summer phase of the 2022 drill campaign began in early June with two diamond drill rigs operating along the CV5-1 pegmatite corridor. A barge and third drill rig began operating at the site in August and is targeting the mineralized pegmatite(s) from the overlying shallow lake. In early September, one of the drill rigs is planned to move to the recently discovered CV13 pegmatite cluster, located approximately 4.3 km on strike to the southwest of the current drill area, for initial drill testing of that local trend, which extends for more than two (2) km (see news release dated August 10, 2022).

Quality Assurance / Quality Control (QAQC)
A Quality Assurance / Quality Control protocol following industry best practices was incorporated into the program and included systematic insertion of quartz blanks and certified reference materials into sample batches, as well as collection of quarter-core duplicates, at a rate of approximately 5%. Additionally, analysis of pulp-split and course-split sample duplicates were completed to assess analytical precision at different stages of the laboratory preparation process, and external (secondary) laboratory pulp-split duplicates were prepared at the primary lab for subsequent check analysis and validation.
All core samples collected were shipped to SGS Canada’s laboratory in Lakefield, ON, for standard sample preparation (code PRP89) which includes drying at 105°C, crush to 75% passing 2 mm, riffle split 250 g, and pulverize 85% passing 75 microns. The pulps were shipped by air to SGS Canada’s laboratory in Burnaby, BC, where the samples were homogenized and subsequently analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (code GE_ICM91A50).
About the CV Lithium Trend
The CV Lithium Trend is an emerging spodumene pegmatite district discovered by the Company in 2017 and spans more than 25-km across the Corvette Property. The core area includes an approximate 2 km long corridor hosting numerous spodumene pegmatites, highlighted by the large CV1 and CV5 pegmatite outcrops, and has returned drill intercepts of 1.65% Li2O and 193 ppm Ta2O5 over 159.7 m (CV22-042), 1.22% Li2O and 138 ppm Ta2O5 over 152.8 m (CV22-030), 2.13% Li2O and 163 ppm Ta2O5 over 86.2 m (CV22-044), and 2.22% Li2O and 147 ppm Ta2O5 over 70.1 m, including 3.01% Li2O and 160 ppm Ta2O5 over 40.7 m (CV22-017). Drilling to date indicates a principal spodumene-bearing pegmatite body of significant size and has been traced by drilling over a distance of at least 2.0 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 relatively closely spaced/stacked, sub-parallel, and sizable spodumene-bearing pegmatite bodies, with significant lateral and depth extent, to be present.
