Vancouver, British Columbia--(Newsfile Corp. - December 18, 2025) - Algo Grande Copper Corp. ("Algo Grande"), formerly Kenadyr Metals Corp. (TSXV: ALGR) (OTC: KNDYF), announces the successful acquisition (the "Acquisition") of 100% ownership of the 5,895-hectare Adelita Copper-Gold-Silver Project (the "Project"). Algo Grande acquired an 80% stake in the Project from Infinitum Copper Corp., and the remaining 20% interest from Minaurum Silver Inc. (TSXV: MGG) (OTCQX: MMRGF). The Project is in the Sonora-Arizona Copper Belt, anchored by the high-grade Cu-Au-Ag Cerro Grande skarn discovery, multiple untested skarn targets along a 6 km corridor, and a 4.5 km porphyry anomaly.

Enrico Gay, CEO of Algo Grande Copper Corp., commented: "Completing the acquisition of 100% of the Adelita Project and securing our reactivation marks an important milestone for Algo Grande. Over the past months, our team has undertaken a rigorous technical review: reprocessing legacy geophysics, rebuilding the geological model, and integrating new data into a modern exploration framework. With this foundation in place, we are now executing a disciplined, data-driven program designed to delineate the scale of both the high-grade skarn system and the porphyry potential at depth. Supported by strong in-country operational partners, and a growing team we are entering this next phase with confidence and clarity of vision."

Conversion of Subscription Receipts

Algo Grande confirms, further to news releases dated August 18, 2025, September 15, 2025, September 26, 2025, and December 15, 2025, that the escrow release conditions for the conversion of 10,198,402 subscription receipts of Algo Grande (the "Subscription Receipts") offered at a price of $0.375 per Subscription Receipt, have been fulfilled. Each Subscription Receipt has converted into one common share of Algo Grande (each a "Share") in accordance with its terms. The proceeds of the Subscription Receipt financing (the "Financing") were being held in escrow pending satisfaction of the escrow release conditions. The proceeds have now been released from escrow and will be used to fund payment obligations and exploration expenditures relating to the Project and for general working capital purposes.

Acquisition of the Project

Algo Grande completed the Acquisition pursuant to the terms and conditions of (a) a share purchase agreement dated June 13, 2025 (the "Infinitum Agreement") with Infinitum Copper Corp. ("Infinitum), pursuant to which Algo Grande acquired 100% of Exploraciones Margarita S.A. de C.V. ("EM"), a private Mexican company holding an 80% interest in the Project, and (b) an asset purchase agreement dated August 12, 2025 (the "Minaurum Agreement") with Minaurum Silver Inc. and Minera Minaurum Gold, S.A. de C.V. ("Minaurum"), a private Mexican company, pursuant to which Algo Grande acquired the remaining 20% interest in the Project from Minaurum.

Under the terms of the Infinitum Agreement, Algo Grande acquired EM in exchange for:

• $100,000 in cash; and
• 1,842,719 Shares, which are subject to voluntary resale restrictions with releases occurring over a period of 18 months.

Infinitum will also receive a post-closing payment of an additional 901,600 Shares in connection with the completion of the Financing.

Under the terms of the Minaurum Agreement, Algo Grande acquired the remaining 20% interest in the Project in exchange for:

• 313,953 Shares; and
• a 1% net smelter return royalty from the sale of any ores, minerals, mineral substances, metals, or concentrates derived from the Property.

All securities issued pursuant to the Acquisition are subject to a statutory hold period of four (4) months plus one (1) day from the date of issuance, in accordance with applicable securities legislation.

Reactivation on the TSX Venture Exchange

The completion of the Acquisition was one of the conditions required by the TSX Venture Exchange (the "TSXV") for Algo Grande's reactivation from the NEX Board of the TSXV onto Tier 2 of the TSXV (the "Reactivation"). Algo Grande expects to receive final approval of the Reactivation upon completion of the remaining filings with the TSXV. The Shares are expected to commence trading on the TSXV on or about December 23, 2025 under the symbol "ALGR" and Algo Grande's classification will change from NEX to Tier 2.

Board and Management Changes

In connection with the Reactivation, Algo Grande wishes to announce changes to its executive leadership team and board of directors (the "Board"). As previously announced, Enrico Gay has been named the Chief Executive Officer of Algo Grande. Additionally, Algo Grande welcomes the appointment of Gord Neal to the Board effective on closing of the Acquisition. Mr. Neal has more than 30 years of management experience in the metals and mining sector, beginning his career as VP of Corporate Development at MAG Silver Corp. and has raised over $750M for various resource companies.

About The Adelita Project

The Adelita Project is anchored by the Cerro Grande Skarn discovery, a high-grade copper-gold-silver system that remains open along strike and to depth. The project benefits from more than US$8 million in historical exploration, including ~7,000 metres of drilling, license-wide VTEM, IP, and magnetic surveys, surface sampling, and detailed geological mapping. Recent reprocessing of these legacy datasets, combined with new modelling, indicates that the skarn system likely continues down-dip beyond 350 metres and extends around a structural fold toward the northwest, outlining a potential 1.2 km mineralized trend from the currently defined 300 m corridor.

Importantly, multiple technical indicators-including potassic feldspar veining, feldspar-porphyry dikes, a high-resistivity magnetic core beneath the skarn, and zoned geochemistry suggest the presence of a porphyry feeder system at depth beneath Cerro Grande. This aligns with classic porphyry-skarn architectures found across northwestern Mexico, including at nearby Piedras Verdes and Alamo Dorado.

To advance this potential, Algo Grande is executing a triangulated Phase 1 program that integrates:

• Oriented-core drilling to define structural controls and geometry;
• A detailed ground magnetic survey to map magnetite-rich horizons and intrusive centers;
• A 50×50 m soil geochemistry program to refine near-surface targets and identify concealed skarn extensions; and
• Reprocessed 3D geophysical inversions to strengthen porphyry target definition.

These datasets will collectively be used to design a Phase 2 drill program planned for Q2 2026, aimed at materially expanding high-grade skarn mineralization along strike and at depth, while also conducting the first deep tests of the interpreted porphyry source. With multi-system potential across a district-scale land package-including skarn, porphyry, and hydrothermal Cu-Zn-Au targets-Adelita represents a rare, underexplored opportunity in the prolific Arizona-Sonora copper belt.
