Director nominees

Dr. Jannas

Dr. Jannas is a globally recognized economic geologist with over 40 years of experience specializing in the exploration of large-scale hydrothermal mineral systems, including porphyry copper-gold and high-sulphidation environments. He has led and advised exploration teams responsible for the discovery and advancement of several world-class deposits, including Pascua Lama, El Morro and the Valeriano (formerly Cortadera) porphyry copper-gold project in Chile, which was discovered and advanced during his tenure as president and chief executive officer of Atex Resources Inc.

Dr. Jannas has held senior technical and executive roles with Atex Resources Inc., Gold Fields, Barrick Gold, LAC Minerals, Hochschild Mining and Metallica Resources, where he played a pivotal role in building high-performance technical teams, designing disciplined exploration strategies, and advancing Tier 1-scale porphyry copper discoveries from concept through resource definition. Most notably, his leadership at Atex Resources helped establish the company as a recognized explorer focused on deep, high-quality porphyry systems within the Andean copper belt.

He holds a PhD in economic geology from Harvard University and is widely regarded as one of the industry's leading authorities on porphyry and high-sulphidation hydrothermal systems. As a director, Dr. Jannas will contribute deep technical insight, strategic perspective and disciplined oversight as Algo Grande advances the Adelita project and evaluates its potential within a broader district-scale hydrothermal copper-gold system.

About Algo Grande Copper Corp.

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

The company is dedicated to unlocking the full mineral potential of this underexplored 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 copper-gold-silver skarn discovery, which exhibits strong continuity along a defined corridor extending over six kilometres. 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.
