Grid Metals Corp. Provides Update on Makwa Nickel-Copper-PGE Project
TORONTO, ON / ACCESS Newswire / June 9, 2026 / 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 deposit1 located in Ontario's 'Ring of Fire' mineral district.
Highlights
Results from drilling 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 deposit2 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 no 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:
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
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 2025 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 those 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 higher 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 zone2,3,4. 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 Pd5. 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 grade6. 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 quality control ("QAQC") protocols in 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 project 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.
