About this update from Grid Metals Corp.
TORONTO, ON / ACCESS Newswire / May 5, 2026 / Grid Metals Corp. (TSXV:GRDM) (OTCQB:MSMGF) ("Grid" or the "Company") is pleased to report additional cesium and lithium values from drilling at its 100% owned Falcon West Property (the "Property"). The focus of the Phase 2 drill program is to expand the limits of the Lucy South cesium target area and to complete step-out drill holes within the immediate project area. Cesium is designated a critical metal in both the US and Canada and, at the current time, the potential sources of cesium-bearing pollucite globally are considered extremely limited. Drilling Highlights Notable cesium intercepts from holes LU26-12 to LU26-50 in the Lucy South target area include: 3.65 m grading 2.51% Cs2O including 0.35 m grading 15.1% Cs2O (LU26-19; from 26.1 metres) 2.20 m grading 3.15% Cs2O including 0.56m @ 6.57% Cs2O (LU26-21; from 31.3 metres) 2.25 m grading 2.87% Cs2O (LU26-24; from 18.1 metres) 1.73 m grading 2.44% Cs2O (LU26-25; from 23.3 metres) 2.54 m grading 1.84% Cs2O (LU26-26; from 25.7 metres) 1.78 m grading 1.50% Cs2O (LU26-27; from 15.5 metres) 2.70 m grading 4.34% Cs2O (LU26-33; from 22.2 metres) Drilling also intersected cesium mineralization 75 m north of the Lucy South target area with hole LU26-50 returning 1.24 m grading 2.40% Cs2O (from 20.4 metres). Elevated grades of lithium were also observed in a number of holes (see Appendix 1) including 6.40 m grading 2.95% Li2O (LU26-21), 6.14 m with 2.95% Li2O (LU26-28), 4.25m with 3.81% Li2O (LU26-32), 3.00 m with 3.68% Li2O (LU26-35), 15.4 m with 1.30% Li2O (LU26-37), and 8.30 m with 1.39% Li2O (LU26-49). Grid expects to commence work on an initial cesium resource estimate for Lucy South immediately following receipt of all assays from the Phase 2 program (17 holes are pending). The Company expects to complete the maiden resource in Q3/26.
