Darren L. Smith, Govt Vice President Exploration, feedback: “The 2025 drill marketing campaign at Shaakichiuwaanaan was expansive in scope and accomplished amongst a backdrop of two (2) Mineral Useful resource Estimate updates and a maiden Feasibility Examine for lithium on the CV5 Pegmatite. The marketing campaign included drill testing of latest targets, infill and step-out holes proximal to outlined Li-Cs-Ta Mineral Sources, in addition to condemnation and geomechanical holes in help of growth. I’m pleased to report that, by the groups’ efforts, the Firm achieved its key drilling goals on schedule and underneath funds with the Challenge now additional derisked in direction of growth in addition to a number of new high-potential lithium and caesium zones found.”  

“The emergence of caesium-rich mineralization throughout a number of areas of the Property underscores the robustness and extremely developed nature of the LCT Pegmatite system at Shaakichiuwaanaan. The presence of such high-value mineralization strengthens our confidence within the broader system and its capability to proceed producing discoveries at scale which have the potential to reinforce long-term shareholder worth.” added Mr. Smith.

PMET Sources Inc. (the “Firm” or “PMET”) (TSX: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is happy to announce outcomes from its in depth 2025 drill marketing campaign on the Firm’s wholly-owned Shaakichiuwaanaan Property (the “Property” or “Challenge”), positioned within the Eeyou Istchee James Bay area of Quebec.

The Property hosts one of many largest pegmatite Mineral Sources¹ (Li, Cs, Ta) and Mineral Reserves² (Li) on the planet, located roughly 13 km south of the regional and all–climate Trans-Taiga Highway and powerline infrastructure hall, and is accessible year-round by street. The Firm not too long ago introduced a strong Feasibility Examine for the CV5 Pegmatite, which outlined the Challenge as a possible North American important mineral powerhouse (see information launch dated October 20, 2025).

The 2025 drill marketing campaign on the Property was expansive in nature and included drill testing of a number of Li-Cs-Ta (“LCT”) pegmatite prospects (CV4, CV8, CV12), step-out drilling at CV5 and CV13, infill drilling at CV13, in addition to condemnation and geomechanical drilling in help of growth at CV5 and CV13, respectively. Over the course of the marketing campaign, which was concluded in October, a complete of 57,024 m (245 holes) of diamond drilling was accomplished, of which, outcomes for 41,943 m (173 holes) are reported herein (see Determine 1, and Desk 1 by Desk 7).

CV4 Pegmatite

The CV4 Pegmatite, characterised at floor by a number of LCT pegmatite outcrops, is located roughly 1.5 km alongside geological development to the east of the CV5 Pegmatite. The 2025 marketing campaign marked the maiden drill testing of the prospect with a complete of 7,513 m (17 holes) accomplished, of which, outcomes for 3,259 m (9 holes) are introduced herein (see Determine 2, Desk 1, and Desk 7).  

A drill fence was accomplished throughout the interpreted strike of the pegmatite outcrops after which continued south in an effort to intersect a possible extension of the principal pegmatite at CV5. The preliminary outcomes point out the outcrops have solely restricted depth extent; nevertheless, the drill fence efficiently intersected vital widths of well-mineralized spodumene pegmatite at depth. Drill outcomes embody:

• 27.0 m at 1.14% Li₂O together with 19.2 m at 1.45% Li₂O; and 13.0 m at 1.37% Li₂O (CV25-1013).
• 11.5 m at 1.27% Li₂O (CV25-950).
• 13.6 m at 0.90% Li₂O; and 20.2 m at 0.75% Li₂O together with 7.9 m at 1.41% Li₂O (CV25-942).

A preliminary assessment of the core signifies that the mineralization fashion in CV4 drill holes is just like that of the principal pegmatite at CV5, characterised by massive spodumene crystals hosted inside a quartz-feldspar pegmatite (Determine 3). The spodumene mineralization consists of off-white to pale-green crystals of centimetre to decimetre scale, that are comparatively freed from inclusions resembling one of many widespread spodumene mineralization types at CV5. This means potential amenability to dense media separation (“DMS”) course of strategies, which in depth testwork at CV5 has demonstrated to be very efficient.

The discovery is important and, coupled with down-ice boulder discoveries within the space (see information launch dated March 25, 2025) and observations in core, is interpreted to signify a possible 1.5 km extension of the CV5 Pegmatite to the east. As such, the invention expands potential for extra underground sources alongside strike of the present underground Mineral Reserves on the CV5 Pegmatite.

CV12 Pegmatite

The CV12 Pegmatite, characterised at floor by a number of LCT pegmatite outcrops, is located roughly 2.4 km alongside geological development to the northwest of the CV13 Pegmatite. The 2025 marketing campaign adopted up on a single drill gap (2021) on the prospect, with a complete 10,102 m (51 holes) accomplished and all outcomes introduced herein (see Determine 4, Desk 2, and Desk 7).

The drilling was profitable, tracing the pegmatite over a strike size of roughly 850 m, with a number of large and well-mineralized lithium intercepts. Of explicit curiosity are the very excessive grades in extra of two.5% Li₂O over intervals higher than 10 m obtained in two (2) holes, and that are paying homage to the high-grade Vega and Nova zones on the CV13 and CV5 pegmatites, respectively. Drill outcomes embody:

• 29.0 m at 1.31% Li₂O, together with 12.5 m at 2.76% Li₂O (CV25-875).
• 29.4 m at 1.28% Li₂O, together with 11.9 m at 2.86% Li₂O (CV25-894).
• 41.3 m at 0.88% Li₂O, together with 27.5 m at 1.20% Li₂O (CV25-922).

A preliminary assessment of the core signifies that the mineralization fashion in CV12 drill holes is just like that of the pegmatites at CV13, CV5, and CV4, characterised by massive spodumene crystals hosted inside a quartz-feldspar pegmatite. The spodumene mineralization consists of off-white to pale-green crystals of centimetre to decimetre scale, that are comparatively freed from inclusions (Determine 5). This means potential amenability to dense media separation (“DMS”) course of strategies, which in depth testwork at CV5 has demonstrated to be very efficient. Moreover, grades of tantalum in drill gap at CV12 are very sturdy (see Desk 2).

Moreover, drilling has outlined a new caesium zone discovery at CV12 with intercepts together with 3.0 m at 5.82% Cs₂O inside a wider anomalous zone of 23.0 m at 0.98% Cs₂O (CV25-875). Different intercepts embody 1.5 m at 3.30% Cs₂O (CV25-944), 1.4 m at 1.77% Cs₂O (CV25-923), 2.6 m at 1.02% Cs₂O (CV25-894), and 4.4 m at 0.90% Cs₂O (CV25-902). The caesium mineralization was intercepted at shallow depths (sometimes <15 to 50 m vertical depth from floor) and has been traced in a number of holes over an approximate 200 m strike size at ~1 to 4 m thickness. Pollucite, the best caesium host mineral – on account of its excessive caesium content material and ease of restoration – was additionally visually recognized in a number of drill holes (Determine 6). Extra drilling is required to constrain the zone; nevertheless, its shallow depth, lengthy strike size, and powerful grades are very encouraging.

CV13 Pegmatite

The 2025 drilling on the CV13 Pegmatite included infill and step-out holes, and geomechanical drilling in help of growth. A complete of 23,451 m (106 holes) have been accomplished, of which, outcomes for 9,771 m (59 holes) are introduced herein (see Determine 7, Desk 3, and Desk 7). Assays stay pending for a number of infill and step-out holes on the CV13 Pegmatite, together with the high-grade (Li, Cs, Ta) Vega Zone. 

The drilling efficiently prolonged the CV13 Pegmatite northeast roughly 0.7 km in direction of the CV5 Pegmatite with drill intercepts together with 14.6 m at 1.04% Li₂O (CV25-802), 11.7 m at 1.16% Li₂O (CV25-796), and 10.9 m at 1.00% Li₂O together with a really high-grade zone 2.1 m at 3.95% Li₂O (CV25-806). A caesium intercept of 0.9 m at 1.42% Cs₂O (CV25-802) was additionally returned on this space, highlighting the potential for extra caesium enriched lenses to be delineated at CV13. The strike-length of the CV13 Pegmatite now extends roughly 3.2 km and stays open in a number of instructions.

A roughly 100-150 m spaced drill gap fence was accomplished an extra 250 m alongside strike to the northeast, testing the highest 150-200 m from floor; nevertheless, didn’t intersect any materials pegmatite intervals. This means the pegmatite physique might slender and/or deflect (probably to depth under 150-200 m) sooner or later alongside the hall.

Step-out drilling to the northwest of the Vega Zone efficiently prolonged the pegmatite at the least 200 m. The pegmatite intervals in these holes are weakly mineralized in lithium and caesium; nevertheless, carry high-grade tantalum together with 3.8 m at 4,058 Ta₂O₅ ppm (CV25-791). A preliminary interpretation, supported by drill gap and geophysical knowledge, suggests a possible fault on this space, which can have probably offset the Vega Zone northerly the place it stays to be drill examined. The Vega Zone stays open in a number of areas with outcomes for a number of infill and step-out holes pending.

Along with the exploration drilling, a geomechanical drill program on the CV13 Pegmatite was accomplished to help growth and financial research. In collaboration with impartial engineering consultants, a complete of 3,961 m (21 holes, HQ) have been accomplished throughout the realm focusing on each pegmatite and host rock. Samples have been collected for subsequent geomechanical lab testing and downhole optical/ acoustic televiewer surveys accomplished to help mine design and geological modelling. Assay outcomes for pegmatite intervals in these holes stay to be reported.

CV5 Pegmatite

The 2025 drilling on the CV5 Pegmatite and areas proximal in help of its growth included step-out holes to the southwest in addition to condemnation holes of proposed waste rock stockpiles and different key infrastructure areas. A complete of 13,591 m (60 holes) have been accomplished with all outcomes introduced herein (see Determine 7, Desk 4, Desk 5, and Desk 7).

Drilling to check a southwestern extension of CV5 (7,101 m over 18 holes) was profitable and traced the pegmatite roughly 0.4 km additional alongside strike on this path. Outcomes embody 24.9 m at 1.34% Li₂O, together with 11.2 m at 2.16% Li₂O (CV25-879), 9.4 m at 1.13% Li₂O (CV25-885), and 15.1 m at 0.98% Li₂O (CV25-885). The strike-length of the CV5 Pegmatite now extends roughly 5.0 km and stays open in a number of instructions.

Moreover, a high-grade caesium intercept of 1.0 m at 9.1% Cs₂O was returned in drill gap CV25-855 over the extension. The interval included the highest-grade particular person caesium pattern collected up to now at CV5 (0.5 m at 17.9% Cs₂O) with huge pollucite visually recognized (Determine 8). This discovery is open in a number of instructions and highlights the potential for well-mineralized pods of caesium (by way of the mineral pollucite) at CV5 as a co-product to lithium and tantalum.

The 2025 drill marketing campaign additionally included condemnation drilling of waste rock Stockpiles 001 and 002 (5,465 m  over 36 holes) in addition to on the underground ramp and air flow shaft (1,025 m  over 6 holes) areas proposed within the not too long ago accomplished lithium-only Feasibility Examine on the CV5 Pegmatite (see information launch dated October 20, 2025) (Determine 2). This drilling achieved its goals of characterizing the native geology in addition to condemning key areas, and can inform the pending Environmental and Social Impression Evaluation (“ESIA”), and deliberate bulk pattern for the Challenge.

CV8 Pegmatite

The CV8 Pegmatite, characterised at floor by a number of LCT pegmatite outcrops, is located roughly 0.5 km south of the CV12 Pegmatite on a sub-parallel development. A complete of 2,523 m (11 holes) have been accomplished, of which, outcomes for 1,312 m (6 holes) are introduced herein (see Determine 4, Desk 6, and Desk 7).

One of the best outcomes from the holes introduced herein on the CV8 Pegmatite are 3.1 m at 1.52% Li₂O and 3.5 m at 1.26% Li₂O – each from drill gap CV25-940A. These intervals additionally returned high-grade tantalum at 321 ppm Ta₂O₅ and 295 ppm Ta₂O₅, respectively.

The goal stays potential and warrants additional drilling given the affiliation with ultramafic rocks proximal (typically strongly related to the widest spodumene pegmatite our bodies on the Property), the massive variety of particular person pegmatite intercepts in drill gap (suggests quantity potential), and the presence of spodumene within the system (lithium funds is current).

Subsequent Steps

The geology workforce is at present decoding and dealing with the brand new drill gap knowledge to advance the host rock and pegmatite geological fashions for the Challenge. The work is concentrated on the CV5 and CV13 pegmatites forward of updates that may feed into up to date block fashions, culminating right into a revised financial research scheduled for the second half of 2026. The information may also inform an underground bulk pattern of mineralized pegmatite at CV5, which is at present being permitted.

Outcomes stay to be reported for 15,081 m (72 holes), of which the overwhelming majority are from infill and step-holes on the CV13 Pegmatite, together with the high-grade (Li-Cs-Ta) Vega Zone. Remaining assay certificates are anticipated to be obtained over the vacations and subsequently outcomes for the ultimate drill holes of the 2025 marketing campaign shall be reported within the new 12 months.
