Aug. 2, 2023 – TheNewswire - Vancouver, Canada - Guyana Goldstrike Inc. (the “Company” or “Goldstrike”) (TSXV:GYA), dba Copper-X Mining Inc., is pleased to announce that the Company has acquired geophysical data from the Government of Chile for use in mineral exploration.  The data includes geophysics showing both regional and property wide magnetic lows (inverse) correlated with copper mineralized zones.  

The property wide magnetic data shows a direct correlation with medium and high-grade copper samples and magnetic lows (the blue zone), particularly near the contact with the medium resistivity readings (the green zone) (see Fig. 1 and 2).  Multiple historic rock samples assayed copper values including in excess of 2.0% copper per tonne (see Fig. 2).  This area, the south-eastern area of Target 1 will be the main focus of exploration.

Both Target 1 and Target 2 have high exploration potential similar to that discovered at Marimaca (see Fig. 3 cross section A-A’ in Target 1). NW-SE trending major structures appear to be conduits/feeders for high-grade copper mineralization forming mantos or stratabound horizons in receptive Andesitic volcanics adjacent to gabbro-microdiorite intrusives.

Exploration Plan

Exploration is expected to commence August 15th, 2023.  The south-eastern area of Target 1 will be the main focus and planned exploration will include:

1. drone based mapping; 

2. geotechnical sampling of approximately 200 samples; 

3. detailed geological mapping of primary zones of interest; 

4. identification of 8-10 drill sites for immediate (no permit required) follow-up drilling; 

5. Completion of a National Instrument 43-101 Technical Report– September 15th, 2023; 

6. to be determined, satellite remote sensing study inclusive of:  

        a. orthographical photo

        b. detailed topography

        c. infrared reflectivity image detailing soil, clay, and rock zones.

Project Highlights

• Property size of 4,000 Hectares 

• Targets 1 & 2 host copper in proximity to historic workings and mine developments. 

• Target 1 has evidence of copper mineralization in a corridor of 3 x 2 kms.  

• Airborne MAG shows that mineralization is consistent with low mag, indicating several untested areas.  

• The abundant microdioritic dykes 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 90kms 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 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.
