PMET Resources Announces New High-Grade Lithium, Caesium, and Tantalum Pegmatite Discoveries in Surface Exploration Works

About this update from Pmet Resources Inc.

PMET's premier James Bay - Quebec geology delivers further exploration success with 2.94% Li2O, 16.43% Cs2O, and 3,768ppm Ta2O5 in surface samples at its Pontois, Shaakichiuwaanaan, and Pontax properties, respectively. HIGHLIGHTS New high-grade caesium pegmatite discovery ("Cosma") situated ~22 km west of the cornerstone CV5 Pegmatite Deposit on the Shaakichiuwaanaan Property: Outcrop grab assay of 9.42% Cs2O and 267 ppm Ta2O5. Channel assay of 4.4 m at 3.61% Cs2O and 609 ppm Ta2O5, including 0.5 m at 16.43% Cs2O. Emerging spodumene pegmatite discovery ("Felix"), located near the western margins of Shaakichiuwaanaan, proximal to the recently acquired Pikwa Property and its Drakkar spodumene pegmatite: Outcrop assays including 1.80% Li2O and 1.21% Li2O. Multiple mineralized outcrops over ~450 m trend.  Drakkar Pegmatite (2.45% Li2O) situated ~550 m to the southwest. Collectively, the Cosma, Felix, and Drakkar Li-Cs-Ta ("LCT") pegmatite clusters extend the prospective Mickel Trend to ~10.5 km in length – from CV9 to Drakkar, with only ~450 m of strike drill tested at CV9. New spodumene pegmatite discovery ("Skald") at the Pontois Property, with outcrop assay of 2.94% Li2O. New caesium pegmatite discovery ("Overload") at the Pontax Property, with outcrop assay of 7.53% Cs2O and 3,768 ppm Ta2O5. Darren L. Smith, Executive Vice President Exploration for the Company, comments: "The recent surface exploration at Shaakichiuwaanaan has delivered multiple new discoveries with strong results that continue to support the scale and growth potential for lithium, caesium, and tantalum across the Property. The discovery of a new caesium-rich LCT pegmatite occurrence (Cosma), located along the highly prospective Mickel Trend – which also hosts the CV9, CV10, CV14, and CV15 pegmatites – supports the presence of a large, highly-evolved, and fertile LCT pegmatite system within the western area of the Property, which has seen only limited drill testing to date. Additionally, the presence of well-mineralized LCT pegmatites at Pikwa, Pontois, and Pontax demonstrates the strength and prospectivity of the Company's broader portfolio of properties," added Mr. Smith.
