Windfall Geotek Delivers Final AI-Driven Nickel, Copper and Cobalt Targets on the Graal Project in Quebec

Coniagas Battery Metals Inc. (TSXV: COS) (“Coniagas” or the “Company”) is pleased to announce with Windfall Geotek Inc. (CSE: WIN; OTCQB: WINKF) ("Windfall"), a pioneer in Artificial Intelligence (AI)-driven mineral exploration since 2005, that Windfall has used its Machine Learning AI System to provide high probability nickel, copper and cobalt exploration targets over the Coniagas Graal project, located in the Saguenay region, Quebec.

The Graal property is strategically located north of Saguenay-Lac St. Jean, in an area with favorable geology for hosting nickel, copper, and cobalt magmatic mineralization associated with the Lac-Saint-Jean Anorthositic Suite (SALSJ).

During the months of March 2026 through to April 2026, hundreds of variables including magnetic, gravimetric, electromagnetic and topographic data along with nickel, copper and cobalt assays data, covering the CONIAGAS Graal Ni-Cu-Co Project, were subjected to an AI evaluation by the Windfall Geotek AI System.

WINDFALL GEOTEK generated a total of eighteen (18) nickel targets, nineteen (19) copper targets and fourteen (14) cobalt targets over the Graal Ni-Cu-Co Project (Figure 1). These exploration targets are identified by the four AI Models based on level of similarity of 85%-90% for nickel, of 80%-85% for copper and 80%-90% for cobalt. Three (3) areas are highlighted simultaneously by all AI Models (Figure 1). These group target zones can be considered as the priority target areas for the Graal Ni-Cu-Co Project.

Michel Fontaine, President and CEO of Windfall Geotek, commented:

"We are thrilled to collaborate with Coniagas Battery Metals on the Graal project. The application of our AI-driven exploration platform, enabled Coniagas to significantly reduce its exploration footprint and focus capital exclusively on the most prospective nickel, copper, and cobalt targets. This collaboration underscores our commitment to providing innovative solutions that accelerate the discovery of essential resources for the global energy transition."

Frank Basa, President and CEO of Coniagas Battery Metals, commented:

"The AI targeting study by Windfall Geotek has reinforced our geological model for the Graal project and sharpened the priority ranking of targets our team had identified from the existing geophysical and geochemical datasets. Having independent, data-driven confirmation of our highest-priority zones gives us added confidence as we plan the next phase of exploration."

About Coniagas Battery Metals

Coniagas Battery Metals Inc. (TSX-V: COS) is a Canadian junior mining company focused on nickel, copper and cobalt and platinum group metals in Québec. Coniagas' strategy is to create value for shareholders through the development of its mineral properties, with the intention to develop Coniagas into a critical metals supplier to the electric vehicle (EV) market. At its 100% owned Graal project near Saguenay, Quebec, Coniagas has conducted successful exploration involving geophysics as well as shallow drilling that hit mineralization in almost every hole. It has confirmed an open-pit deposit model at Graal along a 6 km strike length of high-grade nickel and copper with cobalt, platinum and palladium byproducts. The Company plans in the near-term to conduct additional drilling leading to the production of a Ni 43-101 resource report, metallurgical testing and consultations with First Nations."
