Gold Hart Copper Acquires Mantocobre Gold-Copper IOCG Asset

Toronto, Ontario--(Newsfile Corp. - October 15, 2026) - Gold Hart Copper Corp. (TSXV: HART) ("Gold Hart" or "HART") is pleased to announce that it has acquired the Mantocobre copper-gold IOCG asset. This adds another highly prospective asset to Gold Hart Copper's portfolio of prime properties in Chile. Gold Hart Copper - Mantocobre Asset Highlights Large asset (4,000 hectares / 40km2) strategically located south of Capstone's Mantoverde Property sits directly within 2 parallel mineral belts, Chile's IOCG Belt & the Atacama Fault System, home to world class copper and gold assets Numerous zones of visible copper minerals such as chrysocolla and malachite across the property Several historically mined areas for gold and copper including one 145m long vein, indicating near-surface mineralization Excellent candidate for expedited exploration and development given the visible near-surface mineralization combined with the property's accessibility (paved highway directly to site) Gold Hart CEO Isaac Maresky commented, "Another excellent asset added to the Gold Hart Copper portfolio, with numerous areas of visible mineralization on surface, several historic high grade gold and copper mining pits, genuine potential for expedited development, owned 100% outright with no royalties, with all value accruing to HART shareholders." Gold Hart VP Rodrigo Diaz added, "Mantocobre shows clear evidence of mineralization, hosting numerous copper-gold veins, some of which were historically exploited by artisanal miners, including one up to 145m long. The asset is strategically located in a highly prospective area, approximately 20 km south of Capstone Copper's Mantoverde mine and 60 km north of Copiapó. The property lies within Chile's coastal IOCG belt, and along the Atacama Fault System, which hosts numerous world-class mineral deposits and operating mines. Significant portions of the property are under sediment cover, potentially concealing mineralization that has not been tested by conventional surface exploration and explaining the relatively limited exploration. Most interestingly, in almost every area where the cover is protruded, we are seeing alteration and/or copper minerals of interest." The Company already has geologists and geophysicists on site conducting preliminary geochemical and geophysical surveys, and hopes to be in a position to report on results in the very near future. Although it has had prior owners, Mantocobre was acquired by Gold Hart directly from the government, with little cost to the Company.

All properties are controlled 100% with no royalties whatsoever: https://www.goldhartcopper.com/assets/. Gold Hart Copper Continues to Advance Gold Copper Silver Application ("Pedimento") for Copioso Asset - Historic Mine - to Expand Its Portfolio of Properties In Chile Per the Company's prior announcement, Gold Hart reported that the Company filed an application ("pedimento") for a gold-copper-silver exploration mining concession (the "Application") referred to as the Copioso Asset, to expand its portfolio of prime properties in Chile. The Company reported that it has continued to make progress and has received additional positive confirmations from the Chilean courts, although the process is still not completely finalized. The Company still hopes to be in a position to provide an update in the very near future. Copioso was a historic mine for gold, copper and silver, and the Company has already begun planning various scenarios for exploration and development should the acquisition be completed successfully. Please refer to the Company's prior announcement (May 20, 2026) for more information: https://www.newsfilecorp.com/release/298175/Gold-Hart-Copper-Provides-Updates-on-Drilling-at-Flagship-Tolita-Asset-in-Vicua-District-Geochemical-Survey-at-Nessa-Properties-in-Domeyko-Fault-System-and-New-Property-Application-for-Historic-Gold-Copper-Silver-Asset-Former-Mine Corporate Update & Options Update Per the Company's prior announcement, Gold Hart has added certain key advisors. Given the Company's desire to retain and incentivize exceptional talent while simultaneously minimizing cash salaries, the Company believes stock options to be an integral mechanism for incentivizing and aligning key executives, directors, and advisors. To that end, and per the Company's Stock Option Plan (Rolling 10%), the Company is issuing 14,500,000 options exercisable at $0.20 for 5 years, subject to requisite approvals, bringing total ESOP outstanding to 7.5% of shares with 2.5% remaining available for future issuance(s). Gold Hart has updated its Team page on its website at: https://www.goldhartcopper.com/our-team/ About Gold Hart Copper Gold Hart Copper is one of the largest independent land owners surrounding major miners where the famous Maricunga Gold Belt meets the emerging Vicuña Copper Belt in Chile. HART is actively acquiring, exploring and developing its portfolio of gold, copper & silver properties adjacent to the largest gold and copper assets on the continent2. HART has rolled-up a portfolio of historically significant assets surrounding majors, in some cases personally staked by the very same geologists who made the adjacent mega-discoveries, since the early 1990s. Some of the Gold Hart properties have already undergone a first phase of drilling, with highly encouraging results of gold, copper, silver, and molybdenum. Gold Hart properties are controlled 100% and not subject to any royalties whatsoever. HART believes it may be sitting on one of the only fully-preserved untested large-scale gold-copper-silver porphyry targets in the Vicuña District - an asset that was first recognized for its uniquely high grades of gold and copper on surface - and staked by one of the Maricunga-Vicuña district's pioneering geologists3 in 1993. Gold Hart Copper is fully funded for its planned drill campaign. HART's team of geologists were personally involved in pioneering exploration in the region, leading to some of its greatest gold, copper, and silver deposits, and include the country's former Geological Survey National Deputy Manager Dr. Professor José Frutos. Specifically, senior Gold Hart geologists were personally involved in the Escondida copper discovery, now the largest copper mine in the world5 controlled by Rio Tinto and BHP, as well as Norte Abierto / Cerro Casale, the largest gold-copper discovery in Chile2 acquired by Barrick and Newmont (GoldCorp) with reserves and resources of 50.6-million ounces of gold (0.53g/t), 13.4-billion pounds of copper (0.20%) and 218-million ounces of silver (2.3g/t). In addition to its large land position in the Vicuña District, Gold Hart recently acquired the Nessa properties just northwest on Chile's Paleocene-Eocene Belt on the famous Domeyko Fault System, which is home to some of Chile's largest gold, copper, and silver assets including Escondida, Chuquicamata and Collahuasi. The Nessa properties host several historic gold and copper artisanal mines with high grades of gold, copper, and silver on surface, with a large alteration and magnetic anomaly extending approximately 6km. Kinross' La Coipa Gold Mine sits just east of Nessa. Gold Hart Copper also controls the Mantocobre copper-gold IOCG property, which sits just south of Capstone's Mantoverde Copper Mine, with numerous areas of historic mining pits and mineralization on surface.
