Certain insiders of the company subscribed for an aggregate of 123,333 shares for aggregate gross proceeds of $73,998 in the offering. The insiders' participation constitutes a related-party transaction within the meaning of Multilateral Instrument 61-101 (Protection of Minority Security Holders in Special Transactions). The company is relying on the exemption from the valuation requirements and minority shareholder approvals in MI 61-101 pursuant to subsections 5.5(a) and 5.7(1)(a) of MI 61-101, respectively, as the value of the insiders' participation in the offering does not represent more than 25 per cent of the company's market capitalization, as determined in accordance with MI 61-101.

About Algo Grande Copper Corp.

Algo Grande 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 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.
