Grid Metals Announces Positive Mineralogical Results at Falcon West, Engages SGS Canada for Ore Sorting Test Work, and Announces Investor Relations Agreements

Metallurgy & Processing Marketing Announcement

Grid Metals Announces Positive Mineralogical Results at Falcon

West, Engages SGS Canada for Ore Sorting Test Work, and

Announces Investor Relations Agreements

September 8, 2026 TORONTO -- Grid Metals Corp. (TSXV: GRDM; OTCQB: MSMGF) (“Grid”

or the “Company”) is pleased to report positive mineralogical results from the Lucy South

pegmatite at its Falcon West Property (the “Property”) in southeastern Manitoba. The results

confirm pollucite, the preferred mineral for cesium processing, as the main cesium host mineral

at Lucy South. Accordingly, Grid has engaged SGS Canada to complete an initial >300 kg ore

sorting test program to determine the potential of producing a marketable cesium-bearing pollucite

concentrate. Ore sorting using X -Ray Transmission (“XRT”) is the preferred method to recover

pollucite from ore and is a well -proven approach in the industry. This ore sorting test work will

allow Grid to supply pollucite concentrate to potential end users to test the amenability of the

concentrate for cesium chemical production.

Highlights

• Pollucite is the dominant cesium-bearing mineral in the Lucy South pegmatite.

• Strong liberation performance from the planned ore sorting (XRT) tests are expected

based on the mineralogical and grain size data.

• A strong positive correlation within the Lucy South pollucite zone exists between Cs 2O

grade and pollucite content (linear regression correlation coefficient = 0.98) with 30%

Cs2O equating to 80% pollucite.

• Pollucite is also present in the Lucy North pegmatite.

• A metallurgical study applying ore sorting technology will soon commence. The study will

help constrain the potential of producing a saleable Cs2O (pollucite) concentrate having a

grade in the range of 10-20% Cs2O.

Mineralogical Results

A total of 28 drill core samples from the Artdon and Lucy pegmatites have been analyzed using

QEMSCAN and MLAS semi-quantitative analysis. The analyses were performed at two different

laboratories over a period of 12 months. Twenty-four samples are from Lucy South. Of these, 15

samples are from the pollucite zone, one from the spodumene zone, one from the lepidolite zone,

one from the aplite zone, one from the wall zone, and 5 from the external contact zone where it

features intense biotite alteration and enhanced cesium contents. Three samples were analyzed

from the Lucy North pegmatite. One sample was analyzed from the Artdon pegmatite. Results

are presented in Table 1 below.

Results for the Lucy South pegmatite samples indicate that pollucite is by far the dominant Cs -

bearing phase in the pollucite zone. The only other C s-bearing phases identified within the

pollucite zone are muscovite and, to a le sser extent, biotite. Samples from Lucy South from the

adjacent spodumene, wall, aplite and lepidolite zones do not carry significant quantities of

pollucite. In contrast, some samples from the biotite-rich portions of the contact zones can locally

contain pollucite.

Ore Sorting Test Work

• 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.

• An initial >300 kg composite sample is being shipped to SGS Canada (Lakefield, Ontario)

for grinding, blending and assay. Three size fractions will be produced. These will be

shipped to the Tomra ore sorti ng test facility in Germany in order to determine Cs 2O

recoveries and concentrate grades for each fraction.

• Additional mineral concentration test work is being considered for the fall.

• A microprobe study to determine the chemistry and chemical variability of the pollucite in

the concentrates is also being considered.

About Falcon West

• The focus of the Falcon West joint venture between Grid (85%) and Avenir Minerals

Limited (15%) is to establish a producing cesium operation at the Lucy South cesium zone.

Cesium is a rare critical metal with a number of forward-facing industrial uses. The scope

of the project is to establish a small footprint operation that uses crushing and XRT ore

sorting (no water utilized or extensive infrastructure) in the production of a cesium-bearing

pollucite concentrate to be sold to downstream cesium chemical producers.

• Falcon West consists of 124 unpatented mining claims located 1 30 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 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 globally 1. 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.

About Grid Metals Corp.

The Company is one of the largest mineral rights holders in the Province of Manitoba with over

250,000 hectares of mineral claims and exploration licenses registered to Grid. The current focus

of Grid is its Falcon West Property which is an emerging cesium discovery. A summary of Grid’s

mineral properties in Manitoba include:

1) The Falcon West Property (Li-Cs) is located 130 km east of Winnipeg along the Trans-

Canada highway and contains highly anomalous cesium and lithium values in LCT

pegmatite including the Lucy South pegmatite dyke, the focus of Grid’s current exploration

efforts. The property is subject to a joint venture agreement with Avenir Minerals, which

has a 15% interest in the property.

2) The Makwa Property (Ni-Cu-PGM-Co), which is subject to an Option and Joint Venture

Agreement with Teck Resources Limited (“Teck”). Teck can earn up to a 70% interest

in Makwa by incurring a total of C$17.3 million, comprising project expenditures (C$15.7

million) and cash payments or equity participation (C$1.6 million) with Grid. Makwa is

located on the south arm of the Bird River Greenstone Belt and contains an indicated open

pit resource of 14.2 million tonnes grading 0.48% nickel, 0.11% copper, and 0.37 g/t

palladium2.

3) 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 an indicated

open pit resource of 32.0 million tonnes grading 0.40% copper, 0.16% nickel, and 0.13 g/t

palladium2.
