Grid Metals Continues to Expand Cesium Mineralization at Falcon West

TORONTO, ON / ACCESS Newswire / February 3, 2026 / Grid Metals Corp. (TSXV:GRDM)(OTCQB:MSMGF) ("Grid" or the "Company") is pleased to report additional assays from the Lucy South target zone at its 100%-owned Falcon West cesium property (the "Property"). The Phase 1 drill program was focused on defining a near-surface zone of pollucite-hosted cesium mineralization in the Lucy South pegmatite, which is a highly-fractionated, shallow- to moderately-dipping, lithium+ cesium+tantalum enriched ("LCT") pegmatite dyke that is approximately 10 metres thick. The cesium is largely contained within the mineral pollucite, which is the preferred mineral for processing into cesium chemicals.

Highlights (Drill Holes LU25-12 to 39):

• High-grade cesium intercepts from holes LU25-12 to LU25-39 (see Table 1) include:

  • 7.4m at 6.0% Cs₂O with 3.9 at 10.6% Cs₂O (LU25-18, from 20.75 metres)

  • 8.1m at 5.0% Cs₂O with 2.8m at 13.4% Cs₂O (LU25-21, from 18.35 metres)

  • 12.5m at 5.2% Cs₂O with 3.0m at 20.5% Cs₂O (LU25-36, from 26.55 metres)

• The cesium mineralization has now been defined over an initial area of 100 m x 30 m with an average thickness of approximately five (5) metres. The initial target area remains open in a number of directions.

• High-grade lithium intercepts in the reported drill holes include 4.4m at 3.1% Li₂O (LU25-25) and 5.5 m at 4.7% Li₂O (LU25-32). Most of the known lithium mineralization in the Lucy South pegmatite is associated with spodumene, as confirmed by visual logging and UV light fluorescence testing.

A total of 39 holes have now been reported from the Phase 1 program, in which 67 holes totalling 3,035 metres were completed. A Phase 2 drill program recently commenced and will include both infill and extension drilling around the known pollucite intersections.

Dr. Dave Peck, P. Geo., Grid's Vice President of Exploration, stated "We are pleased to continue to report positive cesium and lithium drill results at Lucy South. We are highly encouraged that the near-surface cesium mineralization appears to be showing good continuity within the initial 100 metre long and 30 metre wide target area. We are also pleased with the continuity and grade of associated lithium (spodumene) mineralization at Lucy South, which is spatially associated with the known pollucite intercepts. With both the cesium and lithium mineralization open in a number of directions, we look forward to testing the open-pit potential of Lucy South with our Phase 2 program."
