Grid Metals Corp. (TSX-V:GRDM) (OTCQB:MSMGF) is pleased to announce additional high-grade cesium assays from the Lucy South target zone at its 100%-owned Falcon West cesium property. The current drill program is defining a high-grade near surface zone of pollucite-hosted cesium mineralization. Cesium is a globally scarce critical metal vital to a number of emerging high-tech applications. It was recently classified as a critical metal by Canada and the United States.

Program Highlights

• High-grade cesium intercepts, including 4.0m at 10.4% Cs₂O with 1.2m at 27.1% Cs₂O (LU25-08) and 3.45m at 16.8% Cs₂O (LU25-09), are amongst the highest Cs₂O drill intercepts reported globally, in recent years.
• Reported drill holes confirm near surface high-grade pollucite-hosted cesium mineralization as well as high-grade lithium and rubidium. Pollucite is a highly sought-after cesium mineral that is the principal feedstock for cesium chemical production.
• Drilling is targeting the southeastern part of the Lucy pegmatite where it forms a flat-lying, near surface and highly fractionated LCT-type (lithium-cesium- and tantalum-enriched) pegmatite that is approximately ten (10) metres thick. A total of 67 drill holes (3,035 metres) were completed in the first phase of the program. Assay results from the remaining 56 drill holes are pending.
• High-grade cesium intercepts are now defined over a strike length of approximately 100 metres, and the cesium enrichment trend remains open in multiple directions, with phase 2 of the drilling campaign expected to commence in mid-January, 2026.

Drill Results Discussion

Highlights from the second batch of assays (holes 6-11) include 4.04 metres with 10.4% Cs₂O and 0.76% Li₂O (LU25-08; from 21.8 metres) and 3.45 metres at 16.8% Cs₂O and 0.86% Li2O (LU25-09; from 15.6 metres).The highest-grade intercept to date in the program was a sub-interval of 1.24m grading 27.1% Cs₂O in drill hole LU25-08.

The initial phase of the current drill program focused on defining the distribution of pollucite within a 150m x 40m near surface target area (Figure 1) using closely-spaced drill hole pierce points into the southeastern part of the Lucy pegmatite.All holes reported to date have intersected a highly fractionated section of the Lucy pegmatite including variably developed subzones enriched in cesium (pollucite +/- mica, feldspar), lithium (spodumene +/- lepidolite), rubidium (feldspar and mica) and tantalum (tantalite). Pollucite, where present, is typically concentrated in the middle of the pegmatite.

The pollucite-enriched part of the southeastern target area is fully open to the north for a distance of over 100 metres and is partly open to the northwest and southeast. Phase 2 of the current drilling program is expected to commence in January and will focus on these adjoining, high potential areas.

Project and Cesium Overview

The Falcon West Cesium Project is one of only three known high-grade cesium exploration projects under development globally. Cesium-rich pollucite ore can be crushed and ore sorted to a high-value pollucite concentrate which is the principal feedstock for cesium chemical production. As such, the capital intensity of producing a high-grade cesium concentrate from near surface material could be extremely low as a conventional mill and tailings facility would not be required.

Cesium is an extremely high-value material with the current price of cesium carbonate trading for US$218,000/t¹, approximately twenty times the value of lithium carbonate. Its unique properties mean it has a wide variety of industrial applications in the oil and gas, optical, medical and next-generation solar industries.

About Grid Metals Corp.

Grid Metals is focused on exploration and development in southeastern Manitoba with four key projects in the Bird River area.

1. The Makwa Property (Ni-Cu-PGM-Co), which is subject to an Option and Joint Venture Agreement with Teck Resources Limited. Teck can earn up to a 70% interest in Makwa by incurring a total of CAD$17.3 million, comprising project expenditures (CAD$15.7 million) and cash payments or equity participation (CAD$1.6 million) with Grid. Makwa is located on the south arm of the Bird River Greenstone Belt.
2. The Mayville Property (Cu-Ni) is located on the north arm of the Bird River Greenstone Belt. The property is owned subject to a minority interest. The project contains a NI 43-101 compliant open pit resource of 32 million tonnes grading 0.61% CuEq.
3. The Falcon West Property (Li-Cs) is located 110 km east of Winnipeg along the Trans-Canada highway and contains highly anomalous cesium values including 3.0 m at 14.0% Cs₂O and 3.5 m at 16.8% Cs₂O.
4. The Donner Property (Li-Cs) is adjacent to the Mayville Property, and Grid owns 75% of the project. The project contains a NI 43-101 compliant resource of 6.8 million tonnes grading 1.39% Li₂O.

All of the Company’s southeastern Manitoba projects are located on the ancestral lands of the Sagkeeng First Nation with whom the Company maintains an Exploration Agreement.
