Grid Metals Corp. Provides Update on Makwa Nickel-Copper-PGE Project

June 9, 2026 TORONTO -- Grid Metals Corp. (TSXV:GRDM; OTCQB:MSMGF) ("Grid" or the

"Company") is pleased to provide an update at its Makwa Ni-Cu-PGE project in southeastern

Manitoba which is subject to an Option and Joint Venture Agreement (the “Agreement”) with Teck

Resources Limited (“Teck”) that was announced in December 2024 . Under the terms of the

Agreement, Teck can earn up to a 70% project interest by incurring $ 15.7 million in work

expenditures and making $ 1.6 million in cash payments to Grid (of which $1 million can be

completed through a subscription of shares at Teck’s election) . The Agreement defines cumulative

exploration expenditures of $3.7M due by May 31 , 2027. To May 31 , 2026, Teck has incurred

expenditures of >$2M, including all committed expenditures. The target model is a footwall-hosted

Ni-Cu-PGE deposit similar to the Eagle ’s Nest deposit 1 located in Ontario’s 'Ring of Fire ’ mineral

district.

Highlights

• Results from d rilling completed in Q4 2025 at the Pavo Anomaly at Makwa intersected

several narrow intervals of massive, semi -massive and net -textured magmatic sulphide

mineralization over a strike length of ~250 metres and to a depth of ~150 metres.

• A deeper electromagnetic (“EM”) anomaly at Pavo (“Pavo Deep”) was identified from

borehole geophysics and has yet to be tested. Pavo Deep is located within the interpreted

main feeder structure on the Property, and the target is modelled as having higher nickel

tenors based on geochemical vectors derived from drill core assays.

• In Q1 2026, ground EM was completed over the Ore Fault deposit 2 which identified a

significant EM anomaly modelled as two highly conductive plates with significant depth

extent of at least 300 to 400 metres. Only two historical drill holes have tested the modelled

east/west striking plate on the outermost edge while n o historical drilling has pierced the

deeper north/south striking plate. The ground EM plate models combined with historical

drilling results indicate the potential for discovering high tenor massive nickel sulphide

mineralization outside of the current limits of the Ore Fault Deposit. Historical drilling at the

Ore Fault deposit includes:

o 15.00 metres with 1.71% Ni and 1.76 g/t Pd in hole MF08-102 (from 187.0m) within a

broader mineralized intersection of mainly disseminated sulphides extending for

53.00 metres averaging 0.82% Ni and 1.15 g/t Pd

o 11.10 metres with 1.98% Ni, 0.57% Cu, 1.96% Zn and 39 g/t Ag in in hole BRM69 -16

(from 2.50m), including 6.80 metres of 2.95% Ni containing a 1.60 metre interval

averaging 9.13% Ni3.

• A decision on future drilling at Pavo Deep and Ore Fault is pending.

Pavo Anomaly Drilling

In Q4 2025, the company completed 8 drill holes totalling 1,954 metres targeting the Pavo Anomaly.

Drilling tested the eastern half of this several hundred-metre-long conductive trend including a

coincident magnetic high. The anomaly extends due west from the interpreted north-south trending

feeder conduit (Ore Fault Corridor) to the regionally extensive Bird River Sill mafic-ultramafic

intrusive complex and its associated disseminated and massive magmatic sulphide deposits and

occurrences. Prospecting along the Pavo Anomaly in May of 202 5 led to the discovery of massive

magmatic sulphide mineralization, referred to as the Blaze Showing (see the Company’s August 11,

2025 news release). The 2025 drilling program intersected multiple, narrow intervals of magmatic

sulphide mineralization typically hosted within several metre - to tens of metres -thick, fine - to

medium-grained mafic intrusive rocks. The mineralization appears to form discrete , discontinuous

sheets that parallel the easterly strike and steep northerly dip of the host mafic intrusive bodies.

The latter intruded a series of felsic to intermediate plutonic rocks and derivative orthogneiss and,

locally, mafic to intermediate metavolcanic rocks . Pavo was an entirely new discovery in the

footwall to the Bird River Sill and validated the model that the Ore Fault Corridor was an important

feeder conduit system to the sill.

The results of the drilling are included in Appendix 1. Maximum grade-thickness is 4.13 metres with

0.85% Ni (hole PAV25 -05 from 102.6 metres) , and maximum nickel grade for individual samples is

1.58% Ni over 0.48 metres (also intersected in hole PAV25 -05 from 105.4 metres). Peak sample

grades reach 1.5% Ni but most of the logged massive to semi -massive magmatic sulphide intervals

contain <1% Ni. This mineralization is also characterized by having background concentrations of

other chalcophile metals including Cu, Pd, Pt and Au. Several mineralized core samples from the

2025 Pavo drill holes were analyzed by Teck’s mineral processing laboratory in Trail, BC. The

mineralogical study identified three distinctive assemblages at Pavo, including a primary magmatic

sulphide population, a high -grade metamorphic mineral assemblage and a lower -temperature

hydrothermal assemblage. Unlike most of the magmatic sulphide occurrences associated with the

Bird River Sill and its interpreted magmatic feeder structures, the Pavo mineralization is

characterized by having much higher proportions of magnetite and pyrite relative to the typical

assemblage of pyrrhotite, pentlandite and chalcopyrite.

The currently favoured interpretation for the Pavo mineralization is that it was downgraded due to

a combination of hydrothermal alteration -causing selective removal of Cu, PGM and Au ; and

equilibration of the primary sulphides with a relatively nickel-poor gabbroic magma - causing the

relatively low nickel grades and tenors compared to th ose associated with most of the magmatic

sulphide deposits in this part of the Bird River Belt . Calculated metal tenors for the Pavo drill core

samples, based on both whole-rock and portable XRF analyses, shows a trend towards the Ore Fault

Corridor of increasing nickel tenor from west to east and top to bottom across the area drilled.

Borehole EM and ground EM surveys were also completed as part of the Q4 exploration program at

Pavo. These surveys confirmed the position of the airborne EM anomalies that motivated the drill

program and also identified a previously unrecognized and untested, highly conductive EM anomaly

near the junction of the Pavo Anomaly and the Ore Fault Corridor (“Pavo Deep”). The nickel tenor

vector discussed above predicts that this plate could be related to h igher grade , massive nickel

sulphide mineralization. This new conductor remains a priority for future exploration efforts at

Pavo.

Ore Fault Target

In Q1 2026, a ground EM survey using the UTEM-5 system operated by Lamontagne Geophysics was

completed over the historic Ore Fault Deposit, located 3 km to the south of the Pavo anomaly within

the Ore Fault Corridor feeder structure. The Ore Fault deposit includes both an ultramafic -hosted

Ni+Cu+Pd+Pt+Co-enriched zone (Nickel Zone) and a directly adjacent Zn+Cu+Ag-enriched zone (Zinc

Zone). Both zones include thicker intervals (e.g. tens of metres thick) of disseminated sulphide

mineralization and narrower intervals (e.g. <1 to several metres thick) of conductive massive, semi-

massive and net-textured sulphides. Maximum grades from historical drilling are >10% Ni, >1% Cu

and >4 g/t Pd in the nickel zone and >10% Zn, >6% Cu and >200 g/t Ag in the zinc zone 2,3,4. In

addition, outcropping massive magmatic sulphide mineralization sampled and analyzed by the

Company in 2024 returned up to 5.97% Ni and 2.04 g/t Pd 5. The new ground EM survey identified

two intersecting conductors including: (1) A steeply east dipping and, north-south striking anomaly

with a high modeled conductance of 2,000 Siemens; (2) A steeply south dipping and east -west

striking anomaly with modeled conductance of 2,050 Siemens. Both anomalies are modeled as

having significant depth extent ranging from 300 to 400 metres. Depth to the tops of the anomalies

is modelled as <50 metres for the East -West conductor and >150 metres for the North -South

conductor. The outermost (and less conductive) edge of the shallower of the two anomalies appears

to have been intersected by two historical drill holes. One of these holes (MF08 -031) encountered

a >30-metre-thick zone of sparsely disseminated magmatic sulphide mineralization within an altered

ultramafic body but did not intersect any conductive massive sulphide mineralization . Historical

drilling adjacent to, but not intersecting the modeled plates for these two conductors encountered

ultramafic-hosted semi-massive to massive sulphide mineralization with peak grade x thickness of

11.10 metres with 1.98% Ni and 0.57% Cu in hole BRM69 -164 and 15.00 metres with 1.71% Ni and

1.76 g/t Pd in hole MF08 -102. Peak grades in these two holes were 1.60 metres with 9.13% Ni in

hole BRM69-16 and 1.00 metres with 4.87% Ni and 3.29 g/t Pd in hole MF08-10.

The ground EM plate models combined with historical drilling results indicate the potential for

discovering high tenor massive nickel sulphide mineralization outside of the current limits of the Ore

Fault Deposit. Detailed evaluation of this geophysical target is being undertaken and a decision on

further follow up work is anticipated in the coming months. In the immediate term , additional

fieldwork and geophysical interpretations are ongoing.

About the Makwa Property

The Makwa Property is one of two copper -nickel-PGM sulphide properties owned by Grid and

located in the Archean -age Bird River greenstone belt in southeastern Manitoba. The project has

excellent infrastructure, e.g., all season roads, local hydro-electric power, proximity to major trans-

continental rail and trucking arteries. The Bird River belt is a direct analogue of the Ring of Fire

district in northwestern Ontario in terms of the variety of mineral deposits types and geology, scale

and structure. The primary target rocks at Makwa are ultramafic cumulates of the >30 km long Bird

River Sill, which represents a dynamic intrusive complex featuring a wide range of intrusion shapes,

sizes and structural associations. Despite its excellent pedigree as a past nickel producer, it was not

until 2023 when Grid completed its consolidation of the nickel -copper sulphide properties in the

belt, that a comprehensive district-scale magmatic sulphide exploration program could be enacted.

In particular, a historical property boundary severely hampered exploration for high -grade massive

sulphide deposits within an interpreted >5 km long feeder system ( Ore Fault Corridor). Prior

exploration efforts were also impaired by the limited depth of penetration of historical geophysical

surveys.

The Makwa project features two past producing nickel sulphide mines, three pit-constrained nickel

sulphide resources (Makwa, Ore Fault and Page deposits, see map – below) and numerous high -

grade nickel - and/or copper -rich magmatic sulphide surface showings. The Company recently

published an updated pit-constrained mineral resource estimate for the Makwa deposit comprising

14.2 MMt of 0.75% Ni Eq grade including a higher -grade core of 4.8 MMt with 1.26% Ni Eq grade 6.

A key aspect of the Makwa mineralization is its high nickel and palladium tenors – making it very

amenable to the production of a high-value nickel sulphide concentrate.

Quality Assurance and Quality Control

Grid Metals applies best practice quality assurance and qual ity control ("QAQC") protocols i n all of

its exploration programs. For the Pavo prospecting program, grab samples were cleaned of obvious

weathering and bagged and tagged in the field. The samples were then transported by secure carrier

to the Actlabs (Thunder Bay) laboratory for sample preparation and analysis for nickel, copper,

cobalt and selected major and trace element abundances using a multi -acid digestion method

followed by ICP-OES analysis. Samples were also analyzed for Pd, Pt and Au using a lead collection

30 g fire assay method followed by ICP-OES analysis. The Company is using several different certified

reference materials ("CRMs") and one analytical blank for the Makwa pro ject to monitor analytical

accuracy and check for cross contamination between samples. The analytical results for the CRMs

and the blank for the new analytical results reported here did not show any significant bias

compared to the certified values and fell within the acceptable limits of variability.
