Grid Metals Intersects High-Grade Cesium at the Falcon West Cesium Project including 14.0% Cs2O over 3.01mTORONTO, ONTARIO / ACCESS Newswire / November 20, 2025 / Grid Metals Corp. (TSXV:GRDM)(OTCQB:MSMGF) ("Grid" or the "Company") is pleased to announce the first five assays from its 2025 cesium-focused drill program at the 100%-owned Falcon West Cesium property (the "Property"). The Property is located approximately 110 km east of Winnipeg, Manitoba. The drill target at Falcon West is pollucite-hosted cesium mineralization within the Lucy South lithium-cesium-tantalum ("LCT") pegmatite. Lucy South is a highly fractionated, shallow, and flat-lying pegmatite which is located approximately 500 metres off the Trans-Canada highway. Initial 2025 drilling has intersected the Lucy South pegmatite including a strongly fractionated core zone carrying high grades of cesium, lithium and rubidium.Highlights from the first five drill holes include:1.73 metres with 14.0% Cs2O, 1.71% Li2O and 0.36% Rb2O (LU25-01; from 27.1 metres) including 0.42 metres with 27.4% Cs2O3.01 metres with 14.0% Cs2O and 0.50% Rb2O (LU25-03; from 31.5 metres) including 0.61 metres with 24.2% Cs2O and 0.50 metres with 24.7% Cs2O2.90 metres with 9.6% Cs2O and 1.85% Li2O (LU25-04; from 25.8 metres) including 0.85 metres with 19.6% Cs2OThe Company is in the process of completing approximately 70 drill holes, focused on delineating the initial near-surface strike and extent of the Lucy South pegmatite and the distribution of cesium within it. The current drill program is the first concerted effort to define the potential for a cesium resource at the Property. The Company is pleased to note that the cesium mineralization in the first five drill holes appears to be primarily associated with the mineral pollucite, the preferred mineral for cesium chemical processing.Dr. Dave Peck, P. Geo., Grid's Vice President of Exploration, stated "Our Falcon West cesium drill program is off to a great start with hole LUC25-03 returning the highest cesium grade-thickness intercept ever recorded at the Property and one of the highest grade-thickness cesium intercepts reported in recent years, globally. Cesium grades north of 20% in drill core are exceptionally rare, marking the Lucy South pegmatite and the Falcon West property as a notable geological target."Robin Dunbar, CEO of Grid Metals, commented, "Cesium is one of the rarest and most sought-after critical metals with a growing number of strategic applications. In the last several months, it has been designated a critical metal by both the U.S. and Canadian governments. The cesium market is facing a global shortfall of feedstock to supply a growing number of applications including defense applications and next-generation solar panels. We are off to a positive start in our efforts to demonstrate that Falcon West has the potential to develop into a globally significant cesium project to support a North American focused cesium supply chain."Drill Results DiscussionThe current area of exploration interest is the near-surface portion of the Lucy South pegmatite where several recent exploration campaigns identified high cesium values. The initial area of interest is an approximate 150x40 m area where the Lucy South pegmatite is within ~35 m of surface. In this initial phase, a substantial portion of the target area will be drilled at closely spaced centres.To date, drilling has identified a distinct zonation pattern of mineralization within the Lucy South pegmatite. Zonation consists of a wall zone on the margins of the pegmatite with variably developed internal subzones enriched in cesium (pollucite +/- biotite), lithium (spodumene +/- lepidolite), rubidium (feldspar +/- biotite) and tantalum (presumed to be associated with columbo-tantalite). The discrete nature of the pegmatite and the distinctive mineral assemblage provides a well-defined exploration target for the ongoing and future drill programs.Figure 1: Map of Lucy South target area with interpreted pierce points into the top of the flat-lying Lucy South LCT pegmatite projected to surface for holes LU25-01 to LU25-05 and previous holes completed in this area. Figure 2: Drill-defined locations of the Lucy South and Artdon LCT pegmatites overlain on a total field magnetic image based on the Company's fall 2024 fixed-wing magnetic and radiometric survey. The dotted white line identifies the current regional exploration target that follows an extensive magnetic low anomaly that hosts both the Artdon and Lucy South pegmatites. The latter two areas may be part of a single LCT pegmatite - but are separated by several hundred metres where no drilling has yet occurred. Next StepsAs discussed, the Company is planning to complete approximately 70 drill holes by the end of 2025 with all holes targeting Lucy South within approximately 35 m of surface. Based on the success of the current program, a follow-up program would likely commence in January 2026.Table 1: Analytica
