ALGO GRANDE COPPER ANNOUNCES UPSIZING OF PRIVATE PLACEMENT

Algo Grande Copper Corp., in response to strong demand, has upsized its previously announced non-brokered private placement of common shares in the capital of the company, originally announced on Aug. 13, 2026.

The upsized offering raises the maximum aggregate gross proceeds from the sale of the shares from $3-million to up to $5-million. The upsized offering will now consist of up to 8,333,333 shares at a price of 60 cents per share. The use of proceeds from the upsized offering will be used to finance continuing drilling and exploration on the company's 100-per-cent-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 cash commissions equal to 6 per cent of the aggregate gross proceeds raised from those purchasers introduced by such finders and issue that number of common share purchase warrants equal to 6 per cent of the number of shares purchased by those purchasers introduced by such finders. Each finder's warrant will entitle the holder thereof to acquire a share at an exercise price of 75 cents 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 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. The company intends to rely on exemptions from the formal valuation and minority shareholder approval requirements of 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.

Algo Grande 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 Cu-Au-Ag (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.

We seek Safe Harbor.
