GOLDSTRIKE / COPPER-X ANNOUNCES EXPLORATION AT JUPITER COPPER PROJECT / ANTOFAGASTA, CHILE

Guyana Goldstrike Inc., doing business as Copper-X Mining Inc., has commenced exploration at the Jupiter copper project for the purpose of completing a National Instrument 43-101 technical report.

A team, inclusive of the company's independent qualified person, has arrived on site at the Jupiter project located 90 kilometres south of Antofagasta, Chile. Initial exploration will include geochemical sampling and geological mapping. Focus will be on areas of historical sampling of known copper (Cu) mineralization in rock outcrop, primarily follow-up exploration to work completed in 2021 (Petrogaia). Initial assays will be delivered to the lab as early as next week. Desktop review of historical geological and geotechnical work has commenced.

Jupiter copper project

Multiple historic rock samples assayed copper values in excess of 2 per cent copper per tonne. The main area of focus surrounds the north-central area of samples 5 and 6, which is correlated to the edge of a magnetometer low (see press release dated Aug. 2). This will be the main focus of exploration moving forward, with the goal of identifying drill pad locations. The continuing exploration program is planned to include:

1. Drone-based mapping;
2. Geotechnical sampling of approximately 300 samples;
3. Detailed geological mapping of primary zones of interest;
4. To be determined, satellite remote sensing study inclusive of:
   1. Orthographical photo;
   2. Detailed topography;
   3. Infrared reflectivity image detailing soil, clay and rock zones.
5. Identification of eight to 10 drill sites for follow-up drilling (no permit required under 20 drill pads and 20,000 metres).

Project highlights:

• Property size of 4,000 hectares.
• Targets 1 and 2 host copper in proximity to historic workings and mine developments.
• Target 1 has evidence of copper mineralization in a corridor of three km by two km.
• Airborne MAG shows that mineralization is consistent with low mag, indicating several untested areas.
• The abundant microdioritic dikes are interpreted to be feeders of high-grade copper mineralization in both gabbro and andesites.
• Numerous targets are interpreted to be present in proximity to contact zones of mafic intrusives and La Negra Fm volcanics -- favourable for hosting hydrothermal solutions rich in copper.
• The main alteration associated with Cu mineralization is albite-epidote-magnetite.
• Mineralization is observed as disseminations and in quartz-albite-epidote veins in fractures as oxide Cu (atacamite-chrysocolla-malachite black oxides).

Project description

The Jupiter project is accessible by paved road 90 km south of Antofagasta city, the major mining hub in northern Chile, with access to renewable power and adjacent to the ocean, to secure access to sea water. The underexplored Jurassic volcanic/IOCG (iron oxide-copper-gold) belt is host to world-class mine operations, including Michilla, Antofagasta's Antucoya, Mantos Copper's Mantoverde and Mantos Blanco, Teck's Carmen de Andacollo, Lundin's Candelaria, Anglo American's El Soldado, and major projects, including Marimaca Copper Corp.'s Marimaca, Hot Chili's Productora-Cortadera and Capstone's Santo Domingo.
