Grit Metals Reports Results from Surface Exploration and Maiden Diamond Drilling Program At Central Finland Lithium Project
Grit Metals Corp. has announced results from its ongoing surface exploration and maiden diamond drilling program at the Company's 100%-owned Central Finland Lithium Project. New spodumene-bearing boulder discoveries in previously untested areas of the Jylhä target, including samples returning assays >2% Li2O. Surface exploration has expanded the known distribution of high-grade spodumene mineralisation at Jylhä and generated new priority areas for bedrock source targeting. Maiden drilling intersected multiple geochemically evolved and highly fractionated pegmatite bodies, confirming a fertile Lithium-Cesium-Tantalum ("LCT") pegmatite system within the Project area. Combined surface and drill results have materially advanced the Company's exploration model and provide new geological and geochemical vectors for the next phase of targeting. During the recent field campaign, the Company completed a focused surface boulder sampling program at Jylhä. The team successfully identified new spodumene-bearing pegmatite boulders in previously untested areas of the permit, with multiple assays returning >0.5% Li2O, in addition to high grade samples of 2.0% and 2.4% Li2O, respectively. Of particular interest is a developing cluster of high-grade and anomalous lithium-bearing boulders east of the Mörkylä area, further expanding the known distribution of spodumene mineralisation at Jylhä and providing a new priority area for follow-up exploration. An additional anomalous cluster in the central part of the permit was also discovered, reinforcing the effectiveness of the Company's systematic boulder prospecting strategy and ability to generate new targets across the broader permit package. Table 1 summarises results of significant samples. A more extensive boulder sampling campaign is planned to further explore the entirety of the Grit licence package, and follow up work programs will take place to advance these new targets. Initial drilling successfully intersected multiple pegmatite bodies and confirmed the presence of a geochemically evolved and highly fractionated pegmatite system within the Project area and at both drilling targets. Geochemical results from the drill intersections demonstrate enrichment in key LCT pathfinder elements and fractionation indicators, including lithium ("Li"), cesium ("Cs"), tantalum ("Ta"), beryllium ("Be"), providing important confirmation of a fertile pegmatite-generating system and strengthening the Company's geological and exploration model. The Company has incorporated these results into a proprietary geochemical targeting model used to vector toward potentially more evolved portions of the pegmatite system. Drilling at Kyrölä identified a muscovite-rich pegmatite horizon in holes KY26-012, KY26-017, KY26-018 and KY26-019. The geological character of these pegmatites is comparable to muscovite-rich pegmatites reported in close spatial association with modelled spodumene-bearing pegmatite lenses at Keliber's Rapasaari and Emmes deposits. Additionally, drilling intersected multiple intervals of altered albite- and quartz-rich pegmatite, displaying textural similarities to pegmatites documented at the nearby historic Drägbäcken lithium occurrence, located approximately 6.5 km northwest of Kyrölä and currently held by Arvo Metals. At Drägbäcken, the central portions of the pegmatite have returned lithium assays exceeding 10,000 ppm Li. The comparatively lower lithium tenor of the Kyrölä intersections may indicate that drilling tested a more marginal or less evolved portion of the pegmatite system; however, the geometry, internal zoning and potential extent of these pegmatites remain to be determined through further exploration. As a result of these two styles of pegmatite intrusion at Kyrölä, analysis of key fractionation elements and their respective geochemical relationships has significantly improved the Company's understanding of pegmatite evolution and geochemistry across the target. Developing this geochemical framework is fundamental to effective future exploration and provides the Company with an increasingly refined basis for vectoring towards more evolved and prospective for LCT pegmatite-hosted lithium mineralisation. At Mörkylä, drillhole MK26-007 intersected a 2.90 m alteration interval averaging 250 ppm Li, together with elevated caesium, tin and beryllium values of 46.2 ppm Cs, 27.5 ppm Sn and 5.9 ppm Be. While the interval is not considered economically mineralised, its geochemical signature suggests the hole may have intersected an alteration halo or less evolved part of the system, providing an important spatial vector for follow-up exploration towards potentially more fractionated and lithium-enriched pegmatites in the surrounding and up-ice target area. MK26-007 was the eastmost hole drilled. Combining the assay results with new high grade Li boulders, it is suggestive of an NE geochemical vector for future testing. The degree of pegmatite fractionation and associated LCT pathfinder geochemistry provide valuable vectors toward potentially more evolved and lithium-enriched portions of the pegmatite system. When considered alongside the continued discovery of high-grade spodumene-bearing boulders at surface, the results support Grit's interpretation of a broader fertile LCT pegmatite system and have materially advanced the Company's understanding of the Project and refined the targeting model for the next phase of exploration. Samples were submitted to and prepared at Sodankylä in Finland and analysed at Loughrea in Ireland by ALS Laboratories, an independent commercial laboratory. ALS inserted internal standards, blanks and pulp duplicates within each sample batch as part of their own internal monitoring of quality control protocols. Grit Metals monitors precision and bias performance by inserting certified lithium standards (OREAS 750b, OREAS 754 and GTA-05) as well as blanks and half core duplicates into each batch submitted to ALS at a rate of 1:20. The major element oxides and trace elements including Li, Cs, Ta and Be were analysed by ALS analytical package ME-MS89L involving digestion by Na2O2 fusion followed by ALS's super trace ICP-MS methodology. QAQC results to date do not indicate any analytical accuracy issues with all standards returning values Li values within 3 standard deviations of their certified mean and blanks returning expected values.
