WINDFALL GEOTEK DELIVERS FINAL AI-DRIVEN NICKEL, COPPER AND COBALT TARGETS ON THE CONIAGAS BATTERY METALS' GRAAL PROJECT IN QUEBEC

Windfall Geotek Inc. has used its machine learning AI (artificial intelligence) system to provide high-probability nickel, copper and cobalt exploration targets over the Coniagas Battery Metals' (TSX Venture Exchange: COS) Graal project, located in the Saguenay region, Quebec.

The Graal property is strategically located north of Saguenay-Lac St. Jean, in an area with favourable 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 18 nickel targets, 19 copper targets and 14 cobalt targets over the Graal Ni-Cu-Co project. These exploration targets are identified by the four AI models based on level of similarity of 85 per cent to 90 per cent for nickel, of 80 per cent to 85 per cent for copper and 80 per cent to 90 per cent for cobalt. Three areas are highlighted simultaneously by all AI models. These group target zones can be considered as the priority target areas for the Graal Ni-Cu-Co project.

Michel Fontaine, president and chief executive officer 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 data sets. 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 Inc.

Coniagas Battery Metals (TSX-V: COS) is a Canadian junior mining company focused on nickel, copper, cobalt and platinum group metals in Quebec. Coniagas's 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-per-cent-owned Graal project near Saguenay, Que., 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 six-kilometre 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 National Instrument 43-101 resource report, metallurgical testing and consultations with first nations.

About Windfall Geotek Inc.

Backed by over 41 client discoveries, Windfall Geotek's AI-driven exploration platform is redefining target generation. Through dual-signature modelling, the company ranks and prioritizes zones using the highest similarity scores across independent predictive models. With over two decades of R&D (research and development) investment and a fully cloud-powered infrastructure, the company is now able to compress what traditionally takes months into just days. This integrated approach combining AI, geophysics and geological expertise from senior geologists -- positions Coniagas Battery Metals to dramatically reduce its exploration footprint by up to 99 per cent and focus capital exclusively on the most prospective targets.
