American Marconi Wireless News - Grid Metals Corp. Provides Update on Eagle Copper Exploration Program and Upcoming Copper, Nickel and Cesium Exploration Initiatives

The next planned Grid drill program in the Bird River area is at the Makwa nickel/copper property. Permitting for exploration drilling is well advanced and an ongoing field program at Makwa is focused on the highest priority geophysical targets from the recently completed Geotech Ltd. VTEM™ MAX electromagnetic survey. The Makwa property is subject to an option and joint venture agreement currently funded by Teck Resources Limited.

The Company is also in the process of permitting exploration drilling at the Falcon West property for cesium. The most recent drilling at the Lucy pegmatite (Q1 2024) by Grid intersected 3.20m of 4.6% Cs₂O in a >100-metre-long cesium-enrichment trend. The drill target at Lucy is a near-surface, flat-lying cesium and lithium-enriched portion of the larger Lucy Pegmatite in which most of the cesium is believed to be associated with the primary cesium ore mineral, pollucite. Pollucite is the preferred feedstock to the cesium chemicals industry, including the nearby Tantalum Mining Corporation of Canada Ltd.'s cesium chemical plant. The next phase of drilling at the Lucy Pegmatite will be designed to test the distribution of pollucite within this specific target area.

Eagle Gabbro Exploration Highlights

• New airborne EM surveys completed in Q4 2024 have defined numerous, strong EM anomalies at the Mayville project that could reflect massive magmatic sulfide accumulations.

Dr. Dave Peck, P.Geo., Grid's Vice President of Exploration, stated "The new drill results confirm the mineralized nature at the Eagle gabbro, which is located ~10 km from Grid's existing 32 Mt indicated open-pit, copper-rich Mayville deposit². We are now looking at a ~20 km long mineralized mafic-ultramafic complex having demonstrated potential to expand on the Mayville resource. Moreover, the results from the recent, deep penetrating EM surveys have highlighted the potential for high-grade massive sulfide deposits on the Property. In the future, adding new high-grade resources to the known near-surface disseminated sulfide deposits is seen as the best path forward for this project."

Location of the 1) Mayville Deposit (yellow); 2) the top-ranked and untested conductor anomalies potentially associated with massive Cu-Ni sulfide mineralization at the Mayville project; and 3) the Eagle gabbro area. The map shows the interpreted limits of the Mayville-Eagle Complex (black outline) on a tilt derivative total magnetic intensity background image.

¹ The Mayville deposit is located ~10 km to the west of the Eagle gabbro and is estimated to contain 32.0 million tonnes of indicated resources averaging 0.40% Cu and 0.16% Ni (see the Company's May 6, 2024 news release for details)

² Cu Eq is the copper equivalent grade, calculated as follows: CuEq (%) = Cu% + ((Ni% x NiR x NiP) + (Co% x CoR x CoP) + (Pt g/t x PtR x PtP) + (Pd g/t x PdR x PdP) + (Au g/t x AuR x AuP))/(CuR x CuP) where R = metal recovery and P = metal price. The following fixed metallurgical recoveries were assumed, guided by metallurgical test results reported by Micon International in the current Technical Report for the property (June 2024 - see Company website for details): Cu - 85%; Ni and Co - 60%; Pd, Pt and Au - 70%. The following long-term metal prices in US dollar amounts were assumed: Cu - $4.00/lb; Ni - $9.00/lb; Co - $22.50/lb; Pd - $1,100/oz; Pt - $1,100/oz; Au - $2,200/oz.

³ The New Manitoba deposit has a historical resource estimate of 2.0 million short tons averaging 0.75% Cu and 0.33% Ni (Manitoba Mineral Inventory Card #217). The Company has not been able to verify the historical estimate as relevant and the historical estimate should not be relied on.

Magnetic high anomalies are indicated by warmer colours.

Drill Program and Detailed Results
A total of 4,132 metres were drilled in 25 holes during the Q4 2024 drill program at the Eagle gabbro (Figure 1). Three discrete targets were tested along a ~2 km segment of the Eagle gabbro. These included 11 holes targeting the historical New Manitoba deposit in the south (holes EAG24-01 to 11); 4 holes at a linear magnetic anomaly located ~500m north of the New Manitoba deposit ('E15' target; holes EAG24-13, 14, 16 and 17); and 6 holes at a previously untested disseminated sulfide occurrence at the Acme target area, located 1.2 km north of E15 (holes EAG24-20-25). Two holes were drilled on a conductor (EAG24-016) and a flanking magnetic anomaly (EAG24-17) located ~1 km east of the Eagle gabbro. One hole tested an unmapped magnetic anomaly located along the east side of the Eagle gabbro (EAG24-12). One hole was abandoned (EAG24-15).

All but one of the holes that intersected the Eagle gabbro encountered a steeply-dipping, several metre- to ~40-metre-thick interval of Cu-rich disseminated sulfide mineralization (the 'Eagle Cu Zone'). The average grades and metal tenors for the Eagle Cu Zone closely resemble those characterizing the Mayville deposit. Most of these new drill intersections are shallow (

Table 1. Highlights for the Q4 2024 Eagle drilling program. The true thickness of the drill intersections reported here are estimated to represent 40 - 90% of the interval lengths. Results for drill holes EAG24-01 to 06 were previously reported (see the Company's Dec. 2, 2024 news release).

Geophysical Surveys
Two new airborne EM surveys were completed during the fall and winter of 2024 at the Mayville project area. Geotech Ltd. completed a 143 line km time domain VTEM™ MAX survey over a 3.3 by 4.5 km area at a nominal line spacing of 100 metres and covering the Eagle gabbro in the eastern part of the project area. Geotech also completed a 258 line km deep-penetrating frequency domain EM survey over an 6.8 by 10.4 km area at a nominal 300 metre line spacing covering the central and eastern part of the Mayville-Eagle project area using their proprietary heli-borne ZTEM™ system. Preliminary modeling of the new survey results has identified several strongly conductive anomalies coincident with mapped or interpreted (from magnetics) parts of the 20 km long Mayville-Eagle Complex and with interpreted northeast-striking feeder structures to the complex.

A 5-line pole-dipole IP survey was also completed during the past winter over an area of ~800 metres x 900 metres that covers the historical New Manitoba deposit. The results of the survey highlight a large chargeability anomaly associated with the deposit but extending east and north beyond the known limits of the deposit. The new results highlight an opportunity to expand the historical resources estimated at New Manitoba.

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 current Eagle drilling program, core was logged and sampled at the Company's core facility located on the Makwa property. Standard 1.0 metre sample lengths were used. Samples were bagged and tagged and 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 program 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 the fell within the acceptable limits of variability.
