Grit Metals Identifies New Spodumene-Boulder Targets and Confirms Highly Fractionated Pegmatite System Through Recent Drill Program at Central Finland Lithium Project

Vancouver, British Columbia--(Newsfile Corp. - July 28, 2026) - Grit Metals Corp. (TSXV: FIN) (FSE: K9T) (OTCQB: EUEMF) ("Grit" or the "Company") is pleased to announce results from its ongoing surface exploration and maiden diamond drilling program at the Company's 100%-owned Central Finland Lithium Project.

Highlights

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.

Boulder Sampling Results

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 (see Figure 1), with multiple assays returning >0.5% Li₂O, in addition to high grade samples of 2.0% and 2.4% Li₂O (Figure 2), 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.
