Surface grab samples collected at multiple locations over approximately 2 km within the broader Kremer-2 geophysical corridor confirm nickel-copper-cobalt-bearing sulphide mineralization at surface

GATINEAU, QUEBEC – TheNewswire - July 22, 2026 – Ni-Co Energy Inc. (“Ni-Co Energy”, “Ni-Co” or the “Company”) (TSXV: NICE) is pleased to announce certified assay results from 36 grab samples collected in October 2025 during a brief prospecting campaign in the Kremer-2 and Kremer-3 areas. These areas form part of the Kremer critical and strategic minerals project, focused on nickel, copper and cobalt, 100% owned by Ni-Co Energy Inc. and located in the ZEC Lavigne, approximately 90 km north of downtown Montréal, Québec.

Kremer-2 is located southeast of the Kremer-1 zone, a mineralized zone drilled in 2023. Kremer-2 represents the Company’s highest-priority undrilled exploration target. The 2025 ground program was designed to follow up TDEM electromagnetic targets through prospecting, BeepMat and MaxMin electromagnetic surveys to identify conductive sulphide-rich rocks at surface.

The results confirm nickel-, copper- and cobalt-rich sulphide mineralization at multiple verified surface locations at Kremer-2. Eleven of the 33 Kremer-2 samples returned more than 0.5% Ni, including one sample grading 1.21% Ni and one sample grading 1.03% Ni. Ten Kremer-2 samples also returned more than 0.20% Cu; one additional Kremer-3 sample returned 0.25% Cu.

Highlights

• 1.21% Ni, 0.14% Cu and 0.10% Co in sample 07248;

• 1.03% Ni, 0.30% Cu and 0.18% Co in sample 07235;

• 0.89% Ni, 0.15% Cu and 0.10% Co in sample 07244;

• 0.85% Ni, 0.11% Cu and 0.12% Co in sample 07238;

• 0.85% Ni, 0.05% Cu and 0.10% Co in sample 07257;

• 0.83% Ni, 0.23% Cu and 0.14% Co in sample 07219;

• 0.69% Ni, 0.37% Cu and 0.23% Co in sample 07223;

• 0.65% Ni, 0.13% Cu and 0.07% Co in sample 07245;

• 0.64% Ni, 0.16% Cu and 0.08% Co in sample 07218;

• 0.64% Ni, 0.25% Cu and 0.18% Co in sample 07224;

• 0.55% Ni, 0.15% Cu and 0.08% Co in sample 07220;

• 19 of the 36 Kremer-2 and Kremer-3 samples returned 500 ppm Co or more, including 2,036 ppm Co (0.20% Co) in sample 07234 and 2,294 ppm Co (0.23% Co) in sample 07223;

• most of the samples were collected at multiple locations over approximately 2 km within the broader Kremer-2 geophysical corridor;

• three samples were collected farther southeast in the Kremer-3 area;

• field observations locally indicate limited overburden, with sulphide-rich rocks exposed at or near surface in certain areas;

• numerical modelling of the Kremer-2 ground TDEM survey defined northeastern and southwestern conductive axes located within the Morin Anorthosite. To date, all of these conductive axes are associated with nickel-, copper- and cobalt-rich sulphide mineralization;

• gravity and magnetic surveys also indicate the presence of a denser and more magnetic geological body in the Kremer-2 area, interpreted as a possible mafic intrusion;

Management Comments

Alain Tremblay, President and Chief Executive Officer of Ni-Co Energy, stated:

“These initial laboratory results from Kremer-2 are important because they confirm that the target area is no longer only a geophysical anomaly: it now includes multiple occurrences of nickel-copper-cobalt-bearing mineralization confirmed by laboratory assays. Eleven of the 33 Kremer-2 grab samples returned more than 0.5% nickel, including one sample grading more than 1.2% nickel and another grading more than 1.0% nickel. The copper and cobalt values are also encouraging. Kremer-2 remains an early-stage target, and the next step will be to test by drilling whether this surface mineralization has continuity, thickness and significant grades at depth.”

Marc Boivin, P.Geo., Vice-President, Exploration of Ni-Co Energy and the Company’s Qualified Person, added:

“The Kremer-2 results are consistent with our geological interpretation of the area and support the planned drilling on this target. The samples were collected mainly at Kremer-2, at multiple locations over approximately 2 km, along the modelled TDEM conductive axes. Numerical modelling suggests a moderate southwest dip of the conductors. Planning for the next campaign prioritizes Kremer-2, where a dense and magnetic body has been interpreted as a shallow mafic intrusion. The campaign also aims to test the Kremer-1 conductors using a more appropriate geometry in order to better determine the true thicknesses of the mineralized zones intersected in 2023. Borehole electromagnetic surveys are planned to trace and characterize conductive mineralized zones intersected in the holes or to detect nearby zones.”

Kremer Exploration Context

The Kremer Project is interpreted as a nickel-copper-cobalt-bearing sulphide system located within the Morin Anorthosite, near the contact with Grenvillian metasedimentary rocks. Work completed at Kremer-1 has confirmed sulphides containing nickel, copper and cobalt in drill core and at surface. Kremer-2, located southeast of Kremer-1, was prioritized because of coincident surface mineralized showings, electromagnetic conductors, and magnetic and gravity responses.

Assay and Quality Assurance/Quality Control Procedures

Of the 36 rock samples presented in this news release, 19 were submitted to Impact Global Solutions Inc. (“IGS”) and 17 to AGAT Laboratories. Multi-element analyses, including nickel, copper and cobalt, were performed by four-acid digestion with ICP-OES and/or ICP-MS finish.

IGS and AGAT are independent of the Company. The laboratories’ internal quality assurance and quality control procedures included certified reference materials and duplicate analyses. The Company is reviewing its field QA/QC procedures for future programs, including the insertion of field blanks, duplicates and certified reference materials as exploration advances.
