Grid Metals Commissions Mineral Resource Estimate for
Falcon West; Announces Final Assays from Phase 2 Drill
Program
TORONTO, ON / ACCESS Newswire / August 6, 2026 / Grid Metals Corp. (TSXV:GRDM)(OTCQB:MSMGF) ("Grid"
or the "Company") is pleased to announce that it is proceeding with a maiden cesium and lithium mineral resource estimate
("MRE") for the Lucy South pegmatite at its Falcon West Property (the "Property") in southeastern Manitoba. The Property is
subject to a joint venture between Grid Metals and Avenir Minerals Limited ("Avenir"). SGS Canada Inc. has been engaged to
complete the mineral resource estimate in compliance with National Instrument 43-101. The results of the estimate are expected
to be announced this fall. Final assays from the winter 2025/26 Lucy South resource delineation drill program are also contained
below.
On July 31, 2026, Grid announced TSX Venture approval of a definitive joint venture agreement with Avenir where Grid sold
15% of the Falcon West Property to Avenir for C$3,750,000. Following the announcement of a mineral resource estimate, Avenir
will have the right to subscribe for up to 19.99% of Grid's common shares (up from its current 9.9% shareholding). Avenir also
has the right to acquire an additional 15% interest (for a total of 30%) in the Property upon the completion of a Preliminary
Economic Assessment or adoption of a mine plan.
Mineral Resource Estimate
The Company has engaged SGS Canada Inc. to prepare a mineral resource estimate for the Lucy South pegmatite and to
complete a technical report in support of the estimate prepared in compliance with National Instrument 43-101 and the Canadian
Institute of Mining's guidelines for mineral resource estimation. SGS has extensive experience in resource estimation across
multiple ore types and commodities. The mineral resource will be based upon Grid's recent drilling results for the Lucy South
pegmatite.
Falcon West Drill Program
Recent drilling completed at the Property consists of: (1) 26 holes for 2,820.7 metres in the 2024 exploration program; (2)
67 holes for 3,035 metres in Phase 1 of the now concluded resource delineation program; and, (3) 67 holes for 3,075 metres
in Phase 2 of the delineation program. A majority of this drilling targeted the Lucy South pegmatite and, specifically, its
highly-fractionated Cs-Li-Ta-enriched core. The Lucy South pegmatite is one of three occurrences of Cs-Li-Ta
mineralization identified on three contiguous mineral claims located in the northeastern part of the Property. These claims
cover a >1 km x 250 metres target trend referred to as the Artdon-Lucy or ADL trend.
The Lucy South pegmatite intrudes older mafic metavolcanic and gabbroic intrusive rocks. It is approximately 10 meters
thick, relatively flat-lying and has a drill-defined depth from surface ranging from <2 metres to 40 metres.
Resource delineation drilling was focused on the ~5 metre thick, Li-Cs-Ta-enriched core zone and, more specifically, on a
semi-continuous <1m to 4m thick subzone - the Lucy South cesium zone, that is enriched in the primary cesium-bearing
mineral, pollucite.
With its high concentration of cesium (can contain greater than 30% cesium oxide), pollucite is the mineral of choice for
extraction of cesium for processing into value-added cesium chemicals.
Drilling has delineated the core zone of the Lucy South pegmatite over an area of 120 x 50 metres. The resource
delineation holes have an average spacing of 5 to 10 metres.
Final assays were received from the 2026 drilling program (holes LU26-51 to LU26-67) that included short step-out holes
around the perimeter of the Lucy South cesium zone and some infill holes within this zone. Notable intercepts include:
0.63 m grading 3.53% Cs2O and 3.36% Li2O (LU26-51; from 16.0 metres)
2.45 m grading 1.00% Cs2O (LU26-55; from 23.0 metres) including 0.10 m with 4.02% Cs2O and 4.60% Li2O
(also, 4.06% Li2O over 2.9m; from 23.0 metres)
0.88 m of 2.53% Cs2O (LU26-57; from 11.5 metres) including 0.14 m grading 12.5% Cs2O
2.75 m grading 5.44% Cs2O and 1.52% Li2O (LU26-60; from 19.6 metres) including 1.55 m with 8.49% Cs2O
and 0.60 m with 14.4% Cs2O
1.65 m grading 0.99% Cs2O and 3.37% Li2O (LU26-67; from 31.7 metres)
Eight (8) of the 17 drill holes drilled intercepted pollucite mineralization and twelve (12) intercepted spodumene
mineralization.

About Falcon West
Falcon West consists of 124 unpatented mining claims located 130 km east of Winnipeg and is transected by the Trans
Canada Highway. Most of Grid's exploration efforts have focused on the Lucy claims in the northeastern part of the
property.
Starting in October 2025, Grid commenced resource delineation drilling for cesium and lithium targeting the core zone of
the Lucy South pegmatite located at the eastern end of the ADL trend. This campaign concluded in February of 2026.
The Lucy South pegmatite is a ~10 metre-thick, near surface, highly fractionated cesium-lithium-tantalum-enriched
pegmatite body containing a discrete pollucite-rich zone (Lucy South cesium zone). Resource drilling has defined this
cesium zone over an area of ~120 metres x ~50 metres. The known pollucite mineralization occurs over a true thickness of
<1m to 4 metres. The zone remains partially open to the north, east and south.
The pollucite mineralization is interpreted to have formed in the partially crystallized core zone during the last stages of
solidification of the host Lucy South pegmatite, post-dating an overlapping and more continuous zone of spodumene
mineralization.
Exploration potential in the project area remains high with a number of occurrences of spodumene and pollucite
mineralization noted in the immediate project area of >1 km by ~250 metres. Of note is a large gap in historical drilling
between the Artdon LCT pegmatite occurrence in the west and the Lucy South and Lucy North pegmatites in the east. This
800-metre-wide gap remains a high priority target for the next phase of drilling at the Property.
About Cesium and the Cesium Market
Cesium is defined as a critical metal by both Canada and the U.S. It is used in a number of important energy and security related
applications. There are currently no western controlled cesium producing operations in the world. There is currently believed to
be a significant shortage of cesium feedstock globally1. Pollucite has historically been the mineral of choice for cesium extraction
given its high cesium content.
Quality Assurance and Quality Control
The Company's ongoing exploration program at the Falcon West cesium/lithium property is being supervised by Dave Peck,
P.Geo. Grid Metals applies best practice quality assurance and quality control ("QAQC") protocols on all of its exploration
programs. For the current program, all core was logged and sampled at the Company's core facility located on its Makwa nickel
property. Generally, 1.0 metre sample lengths were used. Samples were bagged and tagged and then transported by secure carrier
to the Activation Laboratories facility in Ancaster, Ontario for sample preparation and analysis for lithium, cesium, rubidium,
tantalum and selected major and trace element abundances using a sodium peroxide fusion total digestion method followed by
ICP-OES and ICP-MS analysis. The Company is using two rare metal certified reference materials ("CRMs") and an analytical
blank for the program to monitor analytical accuracy and check for cross contamination between samples. The blank and CRM
results for the reported intervals were determined to fall within the accepted range of deviation from the certified values. A check
assay program using a similar sodium peroxide fusion digestion method has recently been initiated with check samples being
analyzed at AGAT laboratories in Thunder Bay, Ontario.
