Star Metro - Algo Grande Appoints Monica Ospina as ESG Advisor and Advances Digbee ESG Disclosure Submission

Ms. Ospina brings extensive experience in ESG strategy, external affairs, governance, government and Indigenous relations and critical minerals development across the Americas. Throughout her career, she has worked at the intersection of responsible mining, socio-economic inclusion and community engagement, helping integrate ESG considerations into resource projects from the earliest stages of development.

Her work has been recognized across the industry through her role as founder of O Trade, a socio-economic consultancy firm; her position as Social Performance Advisor for the Americas at Rio Tinto; her contribution to the IFC/World Bank Early Stakeholder Engagement Guideline for mineral projects; and her recognition in the WIM100 2022, which highlights leading women shaping the global mining industry.

In conjunction with Ms. Ospina's appointment, Algo Grande is also pleased to announce that the Company is in the final stages of completing its inaugural ESG disclosure submission through the Digbee ESG Platform, a mining-focused ESG disclosure and assessment framework utilized by mining companies, investors and industry stakeholders globally.

Digbee ESG is a mining-specific ESG disclosure and ratings platform designed to help mining companies measure, manage and communicate ESG performance using standardized frameworks aligned with major global ESG standards and investor expectations. The platform is widely used within the mining industry to improve transparency, strengthen ESG governance and support responsible project development. Digbee's framework is specifically designed for mining companies and incorporates independent expert assessment methodologies intended to support comparability and credibility across the sector.

Enrico Gay, CEO of Algo Grande Copper, commented: "Creating positive outcomes for communities, protecting the environment and building long-term relationships are core priorities for Algo Grande as we advance the Adelita Project. We are grateful for the positive relationships already established with the communities surrounding the Adelita Project, but our ambition is to go beyond the minimum requirements typically associated with exploration and land use agreements. We believe the mining industry has a unique opportunity to create lasting benefits for the people and communities closest to these projects, and our goal is to build a true win-win model for everyone involved. I am confident Monica's experience will help strengthen this vision as Algo Grande continues building a modern copper exploration company focused on responsible growth and long-term value creation."

Ms. Ospina commented: "The mining industry plays a critical role in the global energy transition and the development of resilient critical mineral supply chains. What drew me to Algo Grande is the Company's commitment to embedding responsible mining principles from the earliest stages of project development, sending a strong signal to stakeholders and communities that ESG performance will be proactively managed and that progress toward operational readiness will be grounded in trust and long-term value creation. I look forward to supporting the development of the Adelita Project."

About Algo Grande Copper Corp.

Algo Grande Copper Corp. is a growth-focused mineral exploration company advancing the Adelita Project, a district-scale, multi-system copper-silver-gold opportunity positioned in the prolific Arizona-Sonora copper belt.

Algo Grande is dedicated to unlocking the full mineral potential of this under-explored corridor through disciplined data-driven exploration, technical excellence, and a firm commitment to value creation for shareholders. The 5,895-hectare Adelita Project is anchored by the high-grade Cerro Grande Cu-Ag-Au skarn discovery, which exhibits strong continuity along a defined corridor extending over 6 kilometers. Reprocessing of legacy geophysical data and field mapping indicate the presence of a potential porphyry system at depth, suggesting a classic skarn-porphyry mineralization model similar to major deposits found throughout northwestern Mexico.
