UQAC Research Partnership Advances Understanding of Ni -Cu

Mineralization at Coniagas' Graal Property

Vancouver, BC – August 20, 2025 – Coniagas Battery Metals Inc. (TSXV: COS) (“Coniagas” or the

“Company”), today announced its cooperation with Université du Québec à Chicoutimi (UQAC) to

investigate metallogenic processes responsible for nickel-copper sulfide formation at the Company’s

Graal Property, located within the Lac-Saint-Jean Anorthositic Suite (SALSJ). Laurentia Exploration

continues to manage exploration activities while advancing the permitting process.

This work represents a significant academic contribution to understanding Proterozoic anorthositic

mineralization in Quebec's Grenville Province, deposits increasingly recognized for their critical and

strategic metal content. The economic potential of Ni-Cu deposits has been demonstrated by world-

class discoveries like Voisey's Bay in Labrador.

Research Initiative

The master's project at UQAC, led by Professors S. Dare and R-L Simard, focuses on the northern

margin of the Lac-Saint-Jean Anorthositic Suite, in the Lac à Paul region hosting the Discovery, Gravi,

and MHY mineralized zones discovered on Coniagas’s Graal Property.

Having previously mapped and studied petrographic and geochemical data from these showings in

2024, three members of the research team examined and sampled drill core from these zones at the

Company's core shack last month. Their work on petrogeochemical characterization and mapping of

anorthositic facies will help better define geological control and mechanisms responsible for the

genesis and emplacement of these and other Ni-Cu occurrences in the area and will provide essential

knowledge to improve exploration models across the region.

"This partnership exemplifies how academic research can accelerate mineral discovery," states Frank

Basa, Coniagas CEO. "UQAC's work provides critical geological insights while we advance a project

containing nickel, copper, cobalt, and platinum group metals in one of North America's most stable

mining jurisdictions. Quebec offers clean hydroelectric power, established infrastructure, and proximity

to both traditional and emerging markets for these minerals."

2025 Exploration Program

Key activities planned for the coming months include:

• Completion of airborne EM-mag survey with detailed coverage in areas of known prospectivity

• Initiation of diamond drilling campaign

• Integration of UQAC research findings into exploration targeting

• Continued advancement of permitting and stakeholder engagement

The collaboration between industry and academia at Graal demonstrates Quebec's emergence as a

center for critical minerals research and development. As global supply chains reconfigure and

demand for secure, ethically sourced minerals intensifies, projects with strong technical foundations

and academic validation are increasingly valued by investors and end-users alike.

Academic Research: A Foundation for Success

Partnerships with academic research institutions have proven invaluable in shaping the direction and

effectiveness of exploration using:

• Refined models for magmatic sulfide formation and associated metal zonation

• New interpretations of the local geotectonic setting, drawing on deep geophysical data

• New applications of machine learning for anomaly detection in exploration data

Currently, a team from Université de Québec à Chicoutimi (UQAC) is conducting detailed mapping

and studying the petrogeochemical characterization of anorthositic facies and associated

mineralization in the northern margin of the Lac -Saint-Jean Anorthositic Suite in the vicinity of the

Discovery, Gravi, and MHY Ni-Cu mineralized zones.

Proterozoic anorthositic massifs are abundant in the Grenville Province of Quebec and host

mineralization rich in critical and strategic metals.

The master's project at the Université du Québec à Chicoutimi (UQAC), aims to better understand the

metallogenic processes responsible for the formation of Ni-Cu sulfide mineralization associated with

the Lac-Saint-Jean Anorthositic Suite (SALSJ). The study f ocuses on the northern margin of the

SALSJ, more specifically in the Lac à Paul region, which hosts the Discovery, Gravi and MHY

mineralized zones. These studies will provide key information to improving exploration models for such

deposits (Bounour, O., Dare, S., Simard, R-L., Moukhsil, A. 2025. Cartographie à l’aide du XRF portatif

Strategic Context

The global landscape for critical minerals continues to evolve rapidly. While electric vehicle

applications remain important, demand drivers now encompass aerospace alloys, advanced

manufacturing, telecommunications infrastructure, and various industrial applications requiring high-

performance materials. Recent developments in copper -nickel alloy research highlight expanding

applications beyond traditional uses. Quebec's advantages for critical mineral development include:

• Established mining infrastructure and skilled workforce

• The Québec Plan for the Development of Critical and Strategic Minerals 2020-2025

• Proximity to the St. Lawrence Seaway providing ocean access

• Integration with North American manufacturing corridors

• Stable regulatory environment with clear permitting pathways

Commitment to Environmental Responsibility and Community Engagement

Incorporating academic research goes hand-in-hand with our commitment to responsible resource

development. Stakeholder engagement remains a cornerstone of the project, with regular

consultations involving First Nation communities, and local governments. Academic partners are

contributing to knowledge-sharing and public education, fostering a culture of transparency and mutual

respect.

Frank Basa, Coniagas CEO states, “This is a new era of mineral exploration where science,

technology, and community values are equally prioritized. This cooperation between our exploration

team and academic researchers is unlocking new opportunities and setting new standards for the

industry.”

Dr Renée-Luce Simard, Department of Applied Sciences, Université du Québec à Chicoutimi said “We

hope that our findings will offer a clearer picture of the processes that formed copper and nickel

deposits at Graal. This knowledge is crucial for guiding exploration and ensuring sustainable resource

development.”

As the world accelerates toward a low -carbon future, the Graal Cu -Ni Property stands at the

intersection of innovative exploration and academic excellence. The ongoing collaboration between

industry and academia is not only advancing the science of mineral discovery but also ensuring that

resource development proceeds with integrity and respect for the environment and local communities.

The coming year promises to be a defining chapter in the project’s history, setting the stage for

responsible resource development in a changing world.
