Recent staking more than doubles the Graal property to 148 km², with new claims targeting electromagnetic anomalies that align with known magmatic mineralization
Vancouver, BC May 5, 2026 - TheNewswire Coniagas Battery Metals Inc. (TSXV: COS,OTC:CNBMF) ("Coniagas" or the "Company") is pleased to announce that, following the recent completion of a helicopter-borne time-domain electromagnetic (HTDEM) survey over its wholly-owned Graal property, the Company has staked an additional 8,724 hectares of contiguous ground. The acquisition more than doubles the Graal property to a total of 14,837 hectares (148.4 km²) and consolidates Coniagas's position over a magmatic copper-nickel-cobalt sulphide system in the Saguenay-Lac-Saint-Jean region of Quebec.
The expanded property lies within an emerging critical-minerals district supported by established hydroelectric power, road and rail access, and the deep-water Port of Saguenay. Mineralization at Graal occurs as magmatic copper-nickel-cobalt sulphides with platinum and palladium credits, distributed along a known 6-kilometre strike length on Gravi and MHY zone, over which earlier shallow drilling consistently encountered mineralization.
Additionally, the EM inversion made with this survey confirms the interpretation that the massive sulfide mineralisation is forming a low-dipping bowl shape toward the center of the property at MHY-Gravi zones (dipping approximatively 200 to 400 ) with the mineralisation open at depth.
The HTDEM survey covered the 6,113-hectare original claim block at 200-metre line spacing, tightening to 100-metre spacing over the immediate extensions of the known zones, for a total of 468 line-kilometres flown. The resulting electromagnetic responses coincide with the known mineralized trend (figures 1 and 2), refining drill targeting along that trend and identifying additional isolated targets within the existing property. Equally significantly, the survey identified several other untested isolated anomalies within the property and defined extensions at Lac Suzanne-NO located in the north part of the property as well as at Nourricier A and Nourricier B in the south. Comparable signatures in adjacent regional data, of the same character as those over known mineralization, led to the new staking which was selected to bring that ground under a single contiguous land position.
"The HTDEM survey did what we asked of it. It confirmed the targets we already knew about and showed us where the system potentially extends beyond our claim boundary. Doubling the property in response was the disciplined move. We now have a 148-square-kilometre footprint over a magmatic copper-nickel system in one of Quebec's most active critical-minerals corridors, and the next phase of drilling has a clearer map to work from as we advance toward a maiden mineral resource estimate," said Frank J. Basa, Chief Executive Officer of Coniagas.

With drill permits in place, Coniagas plans to advance further work on the established zones and on the new conductors identified by the survey. The following selected intercepts from previous drilling at Graal illustrate the character of the mineralization being targeted:

About Coniagas Battery Metals Inc.
Coniagas Battery Metals Inc. is a Canadian junior mining company focused on the exploration and development of copper, nickel, cobalt and platinum group metals in Québec. The Company is advancing the Graal project through systematic drilling and metallurgical test work toward a maiden NI 43-101 mineral resource estimate, with the longer-term objective of becoming a Quebec-based supplier of critical metals to North American battery and energy-transition supply chains.
At its 100%-owned Graal project in the Saguenay-Lac-Saint-Jean region of Quebec, Coniagas controls 14,837 hectares (148.4 km²) over a magmatic copper-nickel-cobalt sulphide system. Drilling has identified a potential open-pit deposit model along a 6-kilometre mineralized strike length, supported by drill permits and access to regional infrastructure. The Company's near-term work program at Graal includes continued drilling on the targets refined by the HTDEM survey, advancement toward a maiden NI 43-101 mineral resource estimate, metallurgical test work, and ongoing engagement with First Nations. Further information regarding the Graal project is set out in the "NI 43-101 Technical Report Graal Nickel & Copper Project, Saguenay-Lac-St-Jean, Quebec, Canada" dated January 17, 2024, available on the Company's website at https://coniagas.com/.
