THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES FOR DISSEMINATION IN THE UNITED STATES

VANCOUVER, BC / ACCESS Newswire / August 26, 2026 / Algo Grande Copper Corp. ("Algo Grande" or the "Company") (TSXV:ALGR)(OTCID:ALGRF)(FRA:KM00) announces that in response to strong demand, it has upsized its previously announced non-brokered private placement (the "Upsized Offering") of common shares in the capital of the Company (the "Shares") originally announced on August 13, 2026.

The Upsized Offering raises the maximum aggregate gross proceeds from the sale of the Shares from $3,000,000 to up to $5,000,000. The Upsized Offering will now consist of up to 8,333,333 Shares at a price of $0.60 per Share. The use of proceeds from the Upsized Offering will be used to fund ongoing drilling and exploration on the Company's 100%-owned Adelita Project in Sonora, as well as for the payment of additional operating costs and general working capital requirements.

In connection with the Upsized Offering, the Company may pay certain eligible finders (each, a "Finder") a cash commission equal to 6% of the aggregate gross proceeds raised from those purchasers introduced by such Finder and issue that number of common share purchase warrants (each, a "Finder Warrant") equal to 6% of the number of Shares purchased by those purchasers introduced by such Finder. Each Finder Warrant will entitle the holder thereof to acquire a Share (each, a "Finder's Warrant Share") at an exercise price of $0.75 per Finder's Warrant Share for a period of 24 months from the date of issuance.

Securities issued in the Upsized Offering will be subject to a four-month hold period in accordance with applicable securities laws, which will expire four months and one day from the date of closing of the Upsized Offering. The Upsized Offering is not subject to a minimum aggregate number of subscriptions. The Upsized Offering is subject to certain conditions including, but not limited to, receipt of all necessary approvals, including approval of the TSX Venture Exchange.

The Company expects that certain insiders of the Company (the "Insiders") may participate in the Upsized Offering. The participation of Insiders may constitute a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company intends to rely on exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or any state securities laws, and may not be offered or sold within the United States or to U.S. persons unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.

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-gold-silver opportunity positioned in the prolific Arizona-Sonora copper belt.

Algo Grande is dedicated to unlocking the full 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-Au-Ag 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.
