ALGO GRANDE COPPER CLOSES OVERSUBSCRIBED $6.52 MILLION FINANCING AND STRENGTHENS BOARD AT AGM

Algo Grande Copper Corp. has closed its previously announced non-brokered private placement. Three new directors were elected at the company's annual general meeting, held on Feb. 25, 2026.

Pursuant to its news releases dated Feb. 11, 2026, and Feb. 19, 2026, the company has closed its previously announced non-brokered private placement of common shares in the capital of the company, at a deemed price of 65 cents per share. The offering consisted of 10,037,020 shares for aggregate gross proceeds of $6,524,063.

The offering will finance the next phase of exploration at the company's 100-per-cent-owned Adelita project in Sonora, Mexico, focused on a phase II drill program. Phase I drilling at the Cerro Grande skarn intersected multiple stacked Cu-Au-Ag (copper-gold-silver) skarn horizons at depth, including skarn zones that had not been identified by historic drilling. The upcoming program will target expansion drilling at Cerro Grande and first-pass drilling along an approximately six-kilometre prospective limestone corridor hosting multiple, undrilled, outcropping skarn targets. Proceeds from the offering will also be used for additional operating costs and general working capital requirements.

Commenting on the opportunity at Adelita, newly elected director Raymond Jannas stated: "The Adelita project exhibits many of the characteristics we look for in emerging district-scale systems, high-grade skarn mineralization with clear geological vectors toward a deeper potential porphyry source. What excites me most is the combination of compelling geology and a focused, determined team that is executing with discipline. With capital in place and a clear exploration road map, Algo Grande is well positioned to unlock the broader potential of this system."

In connection with the closing of the offering, the company paid certain eligible finders aggregate cash commissions of $169,605.44, being equal to 7 per cent of the aggregate gross proceeds raised from those purchasers introduced by such finders, and issued 355,863 common share purchase warrants, being equal to 7 per cent of the number of shares purchased by those purchasers introduced by such finders. Each finder's warrant entitles the holder thereof to acquire a share at an exercise price of 65 cents per finder's warrant share until the date that is three years after issuance.

Additionally, Canaccord Genuity Corp. acted as financial adviser to the company in connection with the offering. The company paid Canaccord a corporate finance fee of $50,000. The corporate finance fee was settled through the issuance of 76,923 shares at a deemed price of 65 cents per share.

Securities issued in the offering are 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 offering. The 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 also announces that at its annual general meeting, held on Feb. 25, 2026, shareholders approved all matters brought before the meeting, including the election of three new directors, namely Raymond Jannas, Hunter Scharfe and Enrico Gay.

The appointments follow the company's previously announced board strengthening initiatives (see news release dated Feb. 11, 2026).

Certain directors of the company subscribed for an aggregate of 77,155 shares for aggregate gross proceeds of $50,150.75 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 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 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 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.
